Merck and Gilead Provide Update on Phase 3 KEYNOTE-D46/EVOKE-03 StudyJune 8, 2026 4:30 PM
Business Wire Merck (NYSE: MRK), known as MSD outside of the United States and Canada, and Gilead Sciences, Inc. (Nasdaq: GILD) today announced the discontinuation of the Phase 3 KEYNOTE-D46/EVOKE-03 study investigating Gilead’s Trodelvy® (sacituzumab govitecan-hziy) in combination with KEYTRUDA® (pembrolizumab), Merck’s anti-PD-1 therapy, compared to KEYTRUDA monotherapy in certain patients with previously untreated metastatic non-small cell lung cancer, whose tumors expressed PD-L1 (tumor proportion score [TPS] ≥50%). The decision is based on the recommendation from the external Data Monitoring Committee (eDMC) following their review of the data from the pre-specified final analysis of progression-free survival (PFS) and interim analysis of overall survival (OS). This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260608789974/en/ A numerical improvement in PFS was observed, but did not reach statistical significance. The probability of achieving statistically significant OS is unlikely at the planned final analysis. The safety profile of Trodelvy in combination with KEYTRUDA was consistent with the known safety of each agent. No new safety signals were identified with the combination. These data will be presented at a future medical meeting. Regulatory authorities have been informed. Merck will inform study investigators of the recommendation from the DMC and advise patients in the study to speak to their physician regarding treatment. There are no changes to ongoing Trodelvy or Merck studies. The companies are grateful to the patients, families, and healthcare professionals who participated in the KEYNOTE-D46/EVOKE-03 study and contributed to this important work.

About Metastatic Non-Small Cell Lung Cancer Lung cancer is one of the most common cancers worldwide, with an estimated 2.5 million new cases reported globally in 2022. Non-small cell lung cancer (NSCLC) accounts for approximately 80% to 85% of lung cancers, and nearly half of these NSCLC patients are diagnosed only after the disease has spread, when treatment options are more limited and long-term survival remains low. Despite treatment advances, the 5-year survival rate for metastatic NSCLC is less than 10%. While immunotherapy, with or without chemotherapy, is a standard first treatment option, it does not work for everyone, and new treatment options are needed. About KEYNOTE-D46/EVOKE-03 The KEYNOTE-D46/EVOKE-03 study is a global, open-label, randomized Phase 3 trial, sponsored by Merck, evaluating the efficacy and safety of Trodelvy (sacituzumab govitecan-hziy) in combination with KEYTRUDA (pembrolizumab) compared with KEYTRUDA monotherapy in patients with previously untreated metastatic non-small cell lung cancer (mNSCLC) whose tumors express PD-L1 with a tumor proportion score (TPS) ≥50% and do not have sensitizing EGFR, ALK or ROS1 genomic alterations. Approximately 620 patients were enrolled across study sites worldwide. Patients were randomized 1:1 to receive either Trodelvy (10 mg/kg intravenously on Days 1 and 8 of a 21-day cycle) plus KEYTRUDA (200 mg intravenously on Day 1 of a 21-day cycle), or KEYTRUDA monotherapy (200 mg intravenously on Day 1 of a 21-day cycle). KEYTRUDA was administered for up to 35 cycles, and Trodelvy was continued until disease progression, death, unacceptable toxicity or another treatment discontinuation criterion was met. The dual primary endpoints of the study are progression-free survival (PFS) as assessed by blinded independent central review (BICR) according to RECIST v1.1, and overall survival (OS). Secondary endpoints include objective response rate (ORR), duration of response (DOR), patient-reported outcomes (PROs) and safety. More information about the study is available at ClinicalTrials.gov: NCT05609968. About Trodelvy Trodelvy (sacituzumab govitecan-hziy) is a first-in-class Trop-2-directed antibody-drug conjugate. Trop-2 is a cell surface antigen highly expressed in multiple tumor types, including in more than 90% of breast and lung cancers. Trodelvy is intentionally designed with a proprietary hydrolyzable linker attached to SN-38, a topoisomerase I inhibitor payload. This unique combination delivers potent activity to both Trop-2 expressing cells and the tumor microenvironment through a bystander effect. Trodelvy is currently approved in more than 60 countries for second-line or later metastatic triple-negative breast cancer (TNBC) and in more than 50 countries for certain patients with pre-treated HR+/HER2- metastatic breast cancer (mBC). Healthcare professionals have well-established experience with Trodelvy, which has shown generally consistent outcomes across both clinical trials and real-world use in more than 75,000 breast cancer patients across 60+ countries. Trodelvy is currently being evaluated in multiple ongoing Phase 3 trials across a range of tumor types with high Trop-2 expression. These studies with Trodelvy, both in monotherapy and in combination with pembrolizumab, involve earlier lines of treatment for TNBC and HR+/HER2- breast cancer—including in curative settings—as well as in small cell lung and gynecologic cancers, where previous proof-of-concept studies have demonstrated clinical activity. Indications for Trodelvy TRODELVY® (sacituzumab govitecan-hziy) is a Trop-2-directed antibody and topoisomerase inhibitor conjugate indicated for the treatment of adult patients with: Unresectable locally advanced or metastatic triple-negative breast cancer (mTNBC) who have received two or more prior systemic therapies, at least one of them for metastatic disease. Unresectable locally advanced or metastatic hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative (IHC 0, IHC 1+ or IHC 2+/ISH–) breast cancer who have received endocrine-based therapy and at least two additional systemic therapies in the metastatic setting. U.S. Important safety information FOR TRODELVY BOXED WARNING: NEUTROPENIA AND DIARRHEA TRODELVY can cause severe, life-threatening, or fatal neutropenia. Withhold TRODELVY for absolute neutrophil count below 1500/mm3 or neutropenic fever. Monitor blood cell counts periodically during treatment. Primary prophylaxis with G-CSF is recommended for all patients at increased risk of febrile neutropenia. Initiate anti-infective treatment in patients with febrile neutropenia without delay. TRODELVY can cause severe diarrhea. Monitor patients with diarrhea and give fluid and electrolytes as needed. At the onset of diarrhea, evaluate for infectious causes and, if negative, promptly initiate loperamide. If severe diarrhea occurs, withhold TRODELVY until resolved to ≤ Grade 1 and reduce subsequent doses. CONTRAINDICATIONS Severe hypersensitivity reaction to TRODELVY. WARNINGS AND PRECAUTIONS Neutropenia: Severe, life-threatening, or fatal neutropenia can occur as early as the first cycle of treatment and may require dose modification. Neutropenia occurred in 64% of patients treated with TRODELVY. Grade 3-4 neutropenia occurred in 49% of patients. Febrile neutropenia occurred in 6%. Neutropenic colitis occurred in 1.4%. Primary prophylaxis with G-CSF is recommended starting in the first cycle of treatment in all patients at increased risk of febrile neutropenia, including older patients, patients with previous neutropenia, poor performance status, organ dysfunction, or multiple comorbidities. Monitor absolute neutrophil count (ANC) during treatment. Withhold TRODELVY for ANC below 1500/mm3 on Day 1 of any cycle or below 1000/mm3 on Day 8 of any cycle. Withhold TRODELVY for neutropenic fever. Treat neutropenia with G-CSF and administer prophylaxis in subsequent cycles as clinically indicated or indicated in Table 2 of USPI. Diarrhea: Diarrhea occurred in 64% of all patients treated with TRODELVY. Grade 3-4 diarrhea occurred in 11% of patients. One patient had intestinal perforation following diarrhea. Diarrhea that led to dehydration and subsequent acute kidney injury occurred in 0.7% of all patients. Withhold TRODELVY for Grade 3-4 diarrhea and resume when resolved to ≤ Grade 1. At onset, evaluate for infectious causes and if negative, promptly initiate loperamide, 4 mg initially followed by 2 mg with every episode of diarrhea for a maximum of 16 mg daily. Discontinue loperamide 12 hours after diarrhea resolves. Additional supportive measures (e.g., fluid and electrolyte substitution) may also be employed as clinically indicated. Patients who exhibit an excessive cholinergic response to treatment can receive appropriate premedication (e.g., atropine) for subsequent treatments. Hypersensitivity and Infusion-Related Reactions: TRODELVY can cause serious hypersensitivity reactions including life-threatening anaphylactic reactions. Severe signs and symptoms included cardiac arrest, hypotension, wheezing, angioedema, swelling, pneumonitis, and skin reactions. Hypersensitivity reactions within 24 hours of dosing occurred in 35% of patients. Grade 3-4 hypersensitivity occurred in 2% of patients. The incidence of hypersensitivity reactions leading to permanent discontinuation of TRODELVY was 0.2%. The incidence of anaphylactic reactions was 0.2%. Pre-infusion medication is recommended. Have medications and emergency equipment to treat such reactions available for immediate use. Observe patients closely for hypersensitivity and infusion-related reactions during each infusion and for at least 30 minutes after completion of each infusion. Permanently discontinue TRODELVY for Grade 4 infusion-related reactions. Nausea and Vomiting: TRODELVY is emetogenic and can cause severe nausea and vomiting. Nausea occurred in 64% of all patients treated with TRODELVY and Grade 3-4 nausea occurred in 3% of these patients. Vomiting occurred in 35% of patients and Grade 3-4 vomiting occurred in 2% of these patients. Premedicate with a two or three drug combination regimen (e.g., dexamethasone with either a 5-HT3 receptor antagonist or an NK1 receptor antagonist as well as other drugs as indicated) for prevention of chemotherapy-induced nausea and vomiting (CINV). Withhold TRODELVY doses for Grade 3 nausea or Grade 3-4 vomiting and resume with additional supportive measures when resolved to Grade ≤ 1. Additional antiemetics and other supportive measures may also be employed as clinically indicated. All patients should be given take-home medications with clear instructions for prevention and treatment of nausea and vomiting. Increased Risk of Adverse Reactions in Patients with Reduced UGT1A1 Activity: Patients homozygous for the uridine diphosphate-glucuronosyl transferase 1A1 (UGT1A1)*28 allele are at increased risk for neutropenia, febrile neutropenia, and anemia and may be at increased risk for other adverse reactions with TRODELVY. The incidence of Grade 3-4 neutropenia was 58% in patients homozygous for the UGT1A1*28, 49% in patients heterozygous for the UGT1A1*28 allele, and 43% in patients homozygous for the wild-type allele. The incidence of Grade 3-4 anemia was 21% in patients homozygous for the UGT1A1*28 allele, 10% in patients heterozygous for the UGT1A1*28 allele, and 9% in patients homozygous for the wild-type allele. Closely monitor patients with known reduced UGT1A1 activity for adverse reactions. Withhold or permanently discontinue TRODELVY based on clinical assessment of the onset, duration and severity of the observed adverse reactions in patients with evidence of acute early-onset or unusually severe adverse reactions, which may indicate reduced UGT1A1 function. Embryo-Fetal Toxicity: Based on its mechanism of action, TRODELVY can cause teratogenicity and/or embryo-fetal lethality when administered to a pregnant woman. TRODELVY contains a genotoxic component, SN-38, and targets rapidly dividing cells. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with TRODELVY and for 6 months after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with TRODELVY and for 3 months after the last dose. ADVERSE REACTIONS In the pooled safety population, the most common (≥ 25%) adverse reactions including laboratory abnormalities were decreased leukocyte count (84%), decreased neutrophil count (75%), decreased hemoglobin (69%), diarrhea (64%), nausea (64%), decreased lymphocyte count (63%), fatigue (51%), alopecia (45%), constipation (37%), increased glucose (37%), decreased albumin (35%), vomiting (35%), decreased appetite (30%), decreased creatinine clearance (28%), increased alkaline phosphatase (28%), decreased magnesium (27%), decreased potassium (26%), and decreased sodium (26%). In the ASCENT study (locally advanced or metastatic triple-negative breast cancer), the most common adverse reactions (incidence ≥25%) were fatigue, diarrhea, nausea, alopecia, constipation, vomiting, abdominal pain, and decreased appetite. The most frequent serious adverse reactions (SAR) (>1%) were neutropenia (7%), diarrhea (4%), and pneumonia (3%). SAR were reported in 27% of patients, and 5% discontinued therapy due to adverse reactions. The most common Grade 3-4 lab abnormalities (incidence ≥25%) in the ASCENT study were reduced neutrophils, leukocytes, and lymphocytes. In the TROPiCS-02 study (locally advanced or metastatic HR-positive, HER2-negative breast cancer), the most common adverse reactions (incidence ≥25%) were diarrhea, fatigue, nausea, alopecia, and constipation. The most frequent serious adverse reactions (SAR) (>1%) were diarrhea (5%), febrile neutropenia (4%), neutropenia (3%), abdominal pain, colitis, neutropenic colitis, pneumonia, and vomiting (each 2%). SAR were reported in 28% of patients, and 6% discontinued therapy due to adverse reactions. The most common Grade 3-4 lab abnormalities (incidence ≥25%) in the TROPiCS-02 study were reduced neutrophils and leukocytes. DRUG INTERACTIONS UGT1A1 Inhibitors: Concomitant administration of TRODELVY with inhibitors of UGT1A1 may increase the incidence of adverse reactions due to potential increase in systemic exposure to SN-38. Avoid administering UGT1A1 inhibitors with TRODELVY. UGT1A1 Inducers: Exposure to SN-38 may be reduced in patients concomitantly receiving UGT1A1 enzyme inducers. Avoid administering UGT1A1 inducers with TRODELVY. Please see full Prescribing Information, including BOXED WARNING. About KEYTRUDA® (pembrolizumab) injection for intravenous use, 100 mg KEYTRUDA is an anti-programmed death receptor-1 (PD-1) therapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells. Merck has the industry’s largest immuno-oncology clinical research program. There are currently more than 2,800 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient's likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers. Selected KEYTRUDA® (pembrolizumab) Indications in the U.S. Non-Small Cell Lung Cancer KEYTRUDA, in combination with pemetrexed and platinum chemotherapy, is indicated for the first-line treatment of patients with metastatic nonsquamous non-small cell lung cancer (NSCLC), with no EGFR or ALK genomic tumor aberrations. KEYTRUDA, in combination with carboplatin and either paclitaxel or paclitaxel protein-bound, is indicated for the first-line treatment of patients with metastatic squamous NSCLC. KEYTRUDA, as a single agent, is indicated for the first-line treatment of patients with NSCLC expressing PD-L1 [Tumor Proportion Score (TPS) ≥1%] as determined by an FDA-authorized test, with no EGFR or ALK genomic tumor aberrations, and is: Stage III where patients are not candidates for surgical resection or definitive chemoradiation, or metastatic. KEYTRUDA, as a single agent, is indicated for the treatment of patients with metastatic NSCLC whose tumors express PD-L1 (TPS ≥1%) as determined by an FDA-authorized test, with disease progression on or after platinum-containing chemotherapy. Patients with EGFR or ALK genomic tumor aberrations should have disease progression on FDA-approved therapy for these aberrations prior to receiving KEYTRUDA. KEYTRUDA is indicated for the treatment of patients with resectable (tumors ≥4 cm or node positive) NSCLC in combination with platinum-containing chemotherapy as neoadjuvant treatment, and then continued as a single agent as adjuvant treatment after surgery. KEYTRUDA, as a single agent, is indicated as adjuvant treatment following resection and platinum-based chemotherapy for adult patients with Stage IB (T2a ≥4 cm), II, or IIIA NSCLC. See additional selected KEYTRUDA indications in the U.S. after the Selected Important Safety Information. Selected Important Safety Information for KEYTRUDA Severe and Fatal Immune-Mediated Adverse Reactions KEYTRUDA is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death receptor-1 (PD-1) or the programmed death ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, can affect more than one body system simultaneously, and can occur at any time after starting treatment or after discontinuation of treatment. Important immune-mediated adverse reactions listed here may not include all possible severe and fatal immune-mediated adverse reactions. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Early identification and management are essential to ensure safe use of anti–PD-1/PD-L1 treatments. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. For patients with TNBC treated with KEYTRUDA in the neoadjuvant setting, monitor blood cortisol at baseline, prior to surgery, and as clinically indicated. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate. Withhold or permanently discontinue KEYTRUDA depending on severity of the immune-mediated adverse reaction. In general, if KEYTRUDA requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose adverse reactions are not controlled with corticosteroid therapy. Immune-Mediated Pneumonitis KEYTRUDA can cause immune-mediated pneumonitis. The incidence is higher in patients who have received prior thoracic radiation. Immune-mediated pneumonitis occurred in 3.4% (94/2799) of patients receiving KEYTRUDA, including fatal (0.1%), Grade 4 (0.3%), Grade 3 (0.9%), and Grade 2 (1.3%) reactions. Systemic corticosteroids were required in 67% (63/94) of patients. Pneumonitis led to permanent discontinuation of KEYTRUDA in 1.3% (36) and withholding in 0.9% (26) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Pneumonitis resolved in 59% of the 94 patients. Pneumonitis occurred in 8% (31/389) of adult patients with cHL receiving KEYTRUDA as a single agent, including Grades 3-4 in 2.3% of patients. Patients received high-dose corticosteroids for a median duration of 10 days (range: 2 days to 53 months). Pneumonitis rates were similar in patients with and without prior thoracic radiation. Pneumonitis led to discontinuation of KEYTRUDA in 5.4% (21) of patients. Of the patients who developed pneumonitis, 42% interrupted KEYTRUDA, 68% discontinued KEYTRUDA, and 77% had resolution. Pneumonitis occurred in 7% (41/580) of adult patients with resected NSCLC who received KEYTRUDA as a single agent for adjuvant treatment of NSCLC, including fatal (0.2%), Grade 4 (0.3%), and Grade 3 (1%) adverse reactions. Patients received high-dose corticosteroids for a median duration of 10 days (range: 1 day to 2.3 months). Pneumonitis led to discontinuation of KEYTRUDA in 26 (4.5%) of patients. Of the patients who developed pneumonitis, 54% interrupted KEYTRUDA, 63% discontinued KEYTRUDA, and 71% had resolution. Immune-Mediated Colitis KEYTRUDA can cause immune-mediated colitis, which may present with diarrhea. Cytomegalovirus infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Immune-mediated colitis occurred in 1.7% (48/2799) of patients receiving KEYTRUDA, including Grade 4 (

Gilead and Merck Announce Positive Topline Results From Two Phase 3 Studies Evaluating Islatravir/Lenacapavir, an Oral Once-Weekly HIV TreatmentJune 8, 2026 4:35 PM
Business Wire – Novel Investigational Combination Pairs Merck’s Islatravir, a Next-Generation Nucleoside Analog with Distinct Mechanisms of Action, Including Reverse Transcriptase Translocation Inhibition, with Gilead’s Lenacapavir, a First-in-Class Capsid Inhibitor that Disrupts HIV at Multiple Stages of its Lifecycle – – Islatravir/Lenacapavir has the Potential to be the First Approved Long-Acting Oral HIV Treatment Taken Once-Weekly – Gilead Sciences, Inc. (Nasdaq: GILD) and Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today announced that the primary efficacy endpoint at Week 48 was met in both the Phase 3 ISLEND-1 and ISLEND-2 trials with the investigational oral once-weekly single-tablet HIV treatment regimen of islatravir/lenacapavir. The ISLEND trials are evaluating the efficacy and safety of islatravir 2 mg/lenacapavir 300 mg (ISL/LEN) in people with HIV who are virologically suppressed and switched from BIKTARVY® (bictegravir 50 mg/emtricitabine 200 mg/tenofovir alafenamide 25 mg tablets, B/F/TAF) (ISLEND-1) or standard of care antiretroviral regimens (ISLEND-2). The safety profile of ISL/LEN was generally comparable to the comparator regimens studied in the ISLEND trials, and no new safety concerns were identified. Gilead and Merck plan to file the Phase 3 data from the ISLEND trials with regulatory authorities globally and submit the detailed findings for presentation at a future scientific congress. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260608276598/en/ “Long-acting oral therapies represent a new wave of transformational innovation in HIV drug development, with the potential to reshape the landscape of care,” said Jared Baeten, MD, PhD, Senior Vice President, Clinical Development, Virology Therapeutic Area Head, Gilead Sciences. “Innovative oral HIV treatment options that allow for less frequent dosing may make a meaningful difference in the lives of people living with the virus, potentially offering more flexibility and discretion.” The primary efficacy endpoint of ISLEND-1 and ISLEND-2 was the percentage of participants with HIV-1 RNA levels ≥ 50 copies/mL at Week 48, defined by the FDA snapshot algorithm. In the double-blind ISLEND-1 trial, the once-weekly, single-tablet regimen of ISL/LEN was found to be statistically non-inferior to BIKTARVY. In the open-label ISLEND-2 trial, ISL/LEN was found to be statistically non-inferior to standard of care daily oral antiretroviral therapy regimens. The safety profile of ISL/LEN was generally comparable to BIKTARVY in ISLEND-1 and to standard of care antiretroviral regimens in ISLEND-2. “These results underscore the shared focus and commitment that we and our collaborators at Gilead have on continuing research to help people living with HIV. By advancing this investigational novel once-weekly oral regimen of islatravir and lenacapavir, we aim to bring forward a new long-acting oral option that, if approved, would represent the first of its kind with less frequent dosing and further expand options for people living with HIV,” said Dr. Eliav Barr, Senior Vice President, Head of Global Clinical Development and Chief Medical Officer, Merck Research Laboratories. The combination of islatravir and lenacapavir targets multiple stages of HIV-1 replication, potentially offering people with HIV who are virologically suppressed a novel, long-acting oral single-tablet regimen. The potency and pharmacokinetic profiles of islatravir and lenacapavir enable long-acting dosing as a once-weekly tablet for HIV treatment, if approved. Islatravir and lenacapavir in combination are investigational and not approved for use. There is currently no cure for HIV or AIDS. About ISLEND-1 ISLEND-1 (NCT06630286) is a Gilead-sponsored, multicenter Phase 3 randomized, double-blind, active-controlled trialdesigned to evaluate the safety and efficacy of switching to a once-weekly tablet of islatravir/lenacapavir (ISL/LEN) versus continuing treatment with BIKTARVY (bictegravir/emtricitabine/tenofovir alafenamide) in people with virologically suppressed HIV (HIV-1 RNA levels < 50 copies/mL) on BIKTARVY for ≥ 6 months prior to screening. Participants were randomized 1:1 to receive initial doses of ISL/LEN on Day 1 and Day 2 followed by once-weekly ISL/LEN from Day 8 to Week 96 plus placebo-to-match BIKTARVY daily, or BIKTARVY daily plus placebo-to-match initial doses of ISL/LEN on Day 1 and Day 2 and placebo-to-match once-weekly ISL/LEN from Day 8 to Week 96. The primary endpoint was the proportion of participants with HIV-1 RNA ≥ 50 copies/mL at Week 48, as determined by the US FDA-defined snapshot algorithm. Key secondary endpoints included the proportion of participants with HIV-1 RNA ≥ 50 copies/mL at Week 96, as determined by the US FDA-defined snapshot algorithm; the proportion of participants with virologic suppression (HIV viral load < 50 copies/mL per US FDA Snapshot) at Week 48 and Week 96; change from baseline in CD4 cell count at Week 48 and Week 96; and the proportion of participants treated with ISL/LEN who discontinued treatment due to treatment-emergent adverse events. About ISLEND-2 ISLEND-2 (NCT06630299) is a Gilead-sponsored, multicenter Phase 3 randomized, open-label, active-controlled trialevaluating the safety and efficacy of switching to a once-weekly tablet of ISL/LEN versus continuation of standard of care treatment in people with virologically suppressed HIV (HIV-1 RNA levels < 50 copies/mL) on a stable standard of care antiretroviral regimen for ≥ 6 months prior to screening. A standard of care regimen included two or three antiretroviral medicines, including integrase strand transfer inhibitors (INSTI), nucleoside reverse transcriptase inhibitors (NRTIs), boosted protease inhibitors (PI) and non-nucleoside reverse transcriptase inhibitors (NNRTI). Participants either received an initial dose of ISL/LEN followed by once-weekly ISL/LEN from Day 8 to Week 96, or continued their standard of care treatment with two/three antiretroviral medicines up to Week 96. The primary endpoint is the proportion of participants with HIV-1 RNA ≥ 50 copies/mL at Week 48 by FDA-defined Snapshot Algorithm. Key secondary endpoints included the proportion of participants with HIV-1 RNA ≥ 50 copies/mL at Week 96, as determined by the US FDA-defined snapshot algorithm; the proportion of participants with virologic suppression (HIV viral load < 50 copies/mL per US FDA Snapshot) at Week 48 and Week 96; change from baseline in CD4 cell count at Week 48 and Week 96; and the proportion of participants treated with ISL/LEN who discontinued treatment due to treatment-emergent adverse events. About Lenacapavir The multi-stage mechanism of action of lenacapavir is distinguishable from other approved classes of antiretroviral agents. While most antiretrovirals act on one stage of viral replication, lenacapavir is designed to inhibit HIV at multiple stages of its lifecycle and has no known exhibited cross-resistance in vitro to other existing drug classes. Lenacapavir is being evaluated as a long-acting option in multiple ongoing and planned early and late-stage clinical studies in Gilead’s HIV treatment and prevention research program. Lenacapavir is being developed as a foundation for potential future HIV therapies to offer both long-acting oral and injectable options with several dosing frequencies, in combination or as a mono-agent, that help address the individual needs and preferences of people and communities affected by HIV.

About Islatravir (MK-8591) Islatravir (MK-8591) is Merck’s potent, next-generation nucleoside analog that blocks HIV-1 replication by multiple mechanisms including inhibition of reverse transcriptase translocation, resulting in immediate chain termination, and induction of structural changes in the viral DNA (delayed chain termination). Islatravir is anchoring multiple ongoing early and late-stage clinical trials of two-drug regimens in combination with other Merck antiretrovirals for potential treatments for HIV-1. Islatravir is being studied in Phase 3 in combination with Merck’s doravirine (DOR/ISL) as a once-daily pill for treatment of HIV-1 infection in adults with no prior antiviral treatment history and in Phase 2b in combination with Merck’s investigational non-nucleoside reverse transcriptase inhibitor (NNRTI) ulonivirine (MK-8507) as an oral once-weekly treatment for HIV-1.

Tech Sector Pressure Points to Lower Start for Wall Street: Dow Jones, S&P, Nasdaq, FuturesJune 5, 2026 9:16 AM
IH Market News U.S. stock futures indicated a weaker opening on Friday, with technology stocks expected to remain under pressure following renewed concerns over valuations and growth expectations in the semiconductor sector. The negative tone was particularly evident in Nasdaq 100 futures, which declined 1.3%, signaling potential weakness among large-cap technology names at the opening bell. Chip Stocks Continue to Weigh on Sentiment Selling pressure in semiconductor stocks remained a key focus after investors reacted negatively to Broadcom’s (NASDAQ:AVGO) latest outlook. Although the company delivered quarterly results ahead of expectations, its guidance failed to satisfy investors accustomed to increasingly ambitious projections tied to artificial intelligence demand. Daniela Hathorn, Senior Market Analyst at Capital.com, said: “The market is no longer asking whether AI demand is strong, that has largely been established.” She added: “Instead, investors are beginning to question how much of that growth is already reflected in valuations.” According to Hathorn, “In that sense, Broadcom’s results may not have been disappointing, but they were perhaps not enough to justify another leg higher immediately after such a powerful rally.” Strong Jobs Data Raises Interest Rate Concerns Futures extended their losses after the release of the latest U.S. employment report, which showed job creation significantly exceeding market expectations in May. The Labor Department reported that nonfarm payrolls increased by 172,000 positions during the month, following an upwardly revised gain of 179,000 jobs in April. Economists had forecast an increase of 85,000 jobs, compared with the originally reported gain of 115,000 in the prior month. The stronger-than-expected labor market data pushed Treasury yields higher as investors reassessed the likelihood that the Federal Reserve could maintain elevated interest rates for longer than previously anticipated. Dow Reaches New Record Despite Tech Weakness Despite technology sector headwinds, U.S. equities finished mostly higher on Thursday. The Dow Jones Industrial Average led the gains, rising 874.86 points, or 1.7%, to close at a record 51,561.93. The S&P 500 advanced 30.63 points, or 0.4%, ending at 7,584.31. Meanwhile, the Nasdaq Composite lagged behind its peers, slipping 23.02 points, or 0.1%, to finish at 26,830.98. UnitedHealth Drives Dow Higher A major contributor to the Dow’s strong performance was UnitedHealth (NYSE:UNH), whose shares jumped 5.2%. The rally followed an upgrade from Bank of America, which raised its recommendation on the health insurer to Buy from Neutral. Other Dow components also posted solid gains, including American Express (NYSE:AXP), Goldman Sachs (NYSE:GS) and Merck (NYSE:MRK). Broadcom Sell-Off Hits Technology Stocks Technology shares remained under pressure throughout Thursday’s session, largely because of Broadcom’s sharp decline. The semiconductor company fell 12.6% despite reporting fiscal second-quarter earnings that exceeded analyst forecasts. Investors appeared disappointed that Chief Executive Officer Hock Tan did not increase the company’s projection for annual AI-related chip sales, which remains at $100 billion. AJ Bell Head of Markets Dan Coatsworth commented: “Broadcom may have emerged as a key player in the booming AI infrastructure market, with a particular expertise in the custom chips increasingly being used by the likes of Alphabet and Meta.” He added: “However, just like its rival Nvidia, Broadcom is finding that meeting and even slightly beating forecasts is not enough when the market is holding it to such a high standard.” Financial and Healthcare Shares Outperform While technology struggled, several other sectors posted strong gains. Banking stocks rallied sharply, lifting the KBW Bank Index by 3.7% to its highest closing level in nearly four months. Healthcare and pharmaceutical shares also performed strongly, with the NYSE Arca Pharmaceutical Index rising 3.5% and the Dow Jones U.S. Health Care Index advancing 3%. Brokerage firms, biotechnology companies and commercial real estate stocks also finished higher, helping offset weakness in semiconductor and computer hardware shares.

Moderna and Merck Present 5-Year Data for Intismeran Autogene in Combination With KEYTRUDA (pembrolizumab) in Patients With High-Risk Stage III/IV Melanoma Following Complete Resection at the 2026 ASCO Annual MeetingJune 1, 2026 8:00 AM
ACCESS NewswireAt a median 5-year (60.3 months) planned follow-up of the Phase 2b KEYNOTE-942/mRNA-4157-P201 study, intismeran autogene in combination with KEYTRUDA demonstrated a 49% reduction in the risk of recurrence or death and a 59% reduction in the risk of distant metastasis or death compared to KEYTRUDA aloneIntismeran autogene in combination with KEYTRUDA demonstrated an encouraging trend toward overall survival in an exploratory analysis compared to KEYTRUDA alone (HR=0.471; [95% CI, 0.165-1.345])CAMBRIDGE, MA AND RAHWAY, NJ / ACCESS Newswire / June 1, 2026 / Moderna, Inc. (NASDAQ:MRNA) and Merck (NYSE:MRK), known as MSD outside of the United States and Canada, today announced detailed results from a planned five-year follow-up analysis of the Phase 2b randomized KEYNOTE-942/mRNA-4157-P201 study evaluating intismeran autogene (mRNA-4157 or V940), an investigational mRNA-based individualized neoantigen therapy (INT), in combination with KEYTRUDA® (pembrolizumab), Merck's anti-PD-1 therapy, in patients with high-risk melanoma (stage III/IV) following complete resection. These data will be presented today at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting (May 29-June 2) and published simultaneously in ASCO's Journal of Clinical Oncology.With a median follow-up of 60.3 months (range, 50.5-76.4), adjuvant treatment with intismeran autogene in combination with KEYTRUDA continued to prolong recurrence-free survival (RFS), the study's primary endpoint, reducing the risk of recurrence or death by 49% (HR=0.51; [95% CI, 0.294-0.887]) compared to KEYTRUDA alone. Intismeran autogene in combination with KEYTRUDA also continued to demonstrate a meaningful improvement in distant metastasis-free survival (DMFS), a key secondary endpoint of the study, reducing the risk of distant metastasis or death by 59% (HR=0.411; [95% CI, 0.200-0.843]) compared to KEYTRUDA alone. The exploratory endpoint of overall survival (OS) also demonstrated an encouraging trend toward improved OS (HR=0.471; [95% CI, 0.165-1.345]; n=14) with intismeran autogene in combination with KEYTRUDA compared to KEYTRUDA alone. Together, these findings indicate a sustained improvement in RFS and DMFS at five years."With each year of continued follow-up of our Phase 2b study, we gain a more complete picture of the durability of intismeran autogene in combination with KEYTRUDA. Now, with a median follow-up of five years, the sustained recurrence-free survival and distant metastasis-free survival demonstrate the potential long-term benefit of intismeran autogene in combination with KEYTRUDA in melanoma patients at high risk of recurrence," said David Berman, M.D., Ph.D., Chief Development Officer of Moderna. "These findings add to our confidence in the potentially transformative impact of this novel, personalized approach to cancer care made possible by mRNA technology.""The risk of disease recurrence remains high for patients with stage III/IV melanoma following surgery, so we are encouraged by these long-term findings showing that intismeran autogene in combination with KEYTRUDA provided sustained and durable reductions in the risk of recurrence," said Dr. Majorie Green, Senior Vice President and Head of Oncology, Global Clinical Development, Merck Research Laboratories. "These data further reinforce the potential of this individualized approach to address critical gaps in the adjuvant setting and reflect our continued commitment to advancing innovative therapies for patients."The safety profile of intismeran autogene in combination with KEYTRUDA remained consistent with prior analyses. The most common adverse events attributed to intismeran autogene in combination with KEYTRUDA were fatigue (59.6%), injection site pain (59.6%), and chills (51.0%). The majority of the adverse events attributed to intismeran autogene were Grade 1 (31.7%) and Grade 2 (51.9%), with fatigue being the most common Grade 3 event (4.8%) and no Grade 4-5 events. Immune-related adverse events occurred in 45.2% of patients receiving the combination and 44% receiving KEYTRUDA alone. Intismeran autogene in combination with KEYTRUDA did not result in potentiation of immune-related AEs.The findings build on the primary analysis and supportive analysis at an approximately three-year follow-up (34.9 months), presented at the 2024 ASCO Annual Meeting, in which intismeran autogene in combination with KEYTRUDA resulted in a 49% RFS risk reduction and 62% DMFS risk reduction compared to KEYTUDA alone.Additional subgroup and translational dataData from an exploratory subgroup analysis continued to indicate that improvement in RFS was maintained with intismeran autogene in combination with KEYTRUDA across subpopulations, including age, sex, disease state (Stage III/IV), programmed death-ligand 1 (PD-L1) status, BRAF status, tumor mutation burden (TMB) or circulating tumor DNA (ctDNA) status, compared to KEYTRUDA alone.Intismeran autogene plus KEYTRUDA increased T-cell clonal expansion and promoted the emergence of new T-cell clonotypes compared with KEYTRUDA alone. At long-term follow-up, patients receiving the combination demonstrated an approximately 2-fold higher proportion of novel expanded T-cell clonotypes versus KEYTRUDA monotherapy (0.030 vs 0.016 median summed frequency). Higher magnitude increases of these novel T-cell clones was associated with remaining recurrence-free; recurrence-free patients in the combination arm had approximately twice the number of unique novel expanded clonotypes at long-term follow-up (median number 42 vs 20 in recurrence-free vs recurrence patients, respectively). Additional data presented at ASCO (abstract #9564) found that, in a subset of melanoma patients receiving adjuvant combination therapy, these novel clonotypes were linked to intismeran-encoded neoantigens, supporting intismeran's proposed mechanism of action and association with clinical benefit.[1]Ongoing clinical development programsModerna and Merck have nine total Phase 2 and Phase 3 clinical trials underway investigating intismeran autogene in combination with KEYTRUDA across multiple tumor types, including melanoma, non-small cell lung cancer (NSCLC), bladder cancer and renal cell carcinoma. This includes the recent initiation of a Phase 3 study of intismeran autogene as a monotherapy and in combination with KEYTRUDA for the treatment of high-risk Stage I NSCLC (INTerpath-014, NCT07513376).The Phase 3 clinical trial for adjuvant melanoma (INTerpath-001, NCT05933577) and a randomized Phase 2 study for adjuvant renal cell carcinoma (INTerpath-004, NCT06307431) are fully enrolled. Two NSCLC Phase 3 studies, evaluating adjuvant treatment in patients with completely resected NSCLC (INTerpath-002, NCT06077760) and evaluating adjuvant treatment for patients with resectable NSCLC after receiving neoadjuvant KEYTRUDA plus platinum-based chemotherapy (INTerpath-009, NCT06623422), are enrolling. Randomized Phase 2 studies for patients with resected muscle invasive bladder cancer (INTerpath-005, NCT06305767) and resected non-muscle invasive bladder cancer (INTerpath-011, NCT06833073) are enrolling, a Phase 2 study of first-line treatment for patients with metastatic melanoma (INTerpath-012, NCT06961006) and a Phase 2 study of first-line treatment for patients with metastatic squamous NSCLC (INTerpath-013, NCT07221474) are also enrolling.About intismeran autogene (mRNA-4157 or V940)Intismeran autogene is a novel investigational messenger RNA (mRNA)-based individualized neoantigen therapy (INT) consisting of a synthetic mRNA coding for up to 34 neoantigens that is designed and produced based on the unique mutational signature of the DNA sequence of the patient's tumor. Upon administration into the body, the algorithmically derived and RNA-encoded neoantigen sequences are endogenously translated and undergo natural cellular antigen processing and presentation, a key step in adaptive immunity. Individualized neoantigen therapies are designed to train and activate an antitumor immune response by generating specific T-cell responses based on the unique mutational signature of a patient's tumor.About KEYNOTE-942/mRNA-4157-P201 (NCT03897881)KEYNOTE-942 is an ongoing randomized, open-label Phase 2b trial that enrolled 157 patients with high-risk stage III/IV melanoma. Following complete surgical resection, patients were assigned 2:1 (stratified by stage) to receive intismeran autogene (1 mg every three weeks for nine doses) and KEYTRUDA (200 mg every three weeks up to 18 cycles [for approximately one year]) versus KEYTRUDA alone for approximately one year until disease recurrence or unacceptable toxicity. The primary endpoint is RFS, defined as the time from first dose of KEYTRUDA until the date of first recurrence (local, regional or distant metastasis), a new primary melanoma, or death from any cause in the intention-to-treat population. Secondary endpoints include distant metastasis-free survival and safety, and exploratory endpoints include distribution of TMB expression in baseline tumor samples across study arms and their association with the primary RFS endpoint.Key eligibility criteria for the trial included: patients with resectable cutaneous melanoma metastatic to a lymph node and at high risk of recurrence, patients with complete resection within 13 weeks prior to the first dose of KEYTRUDA, patients were disease free at study entry (after surgery) with no loco-regional relapse or distant metastasis and no clinical evidence of brain metastases, patients had a formalin fixed paraffin embedded (FFPE) tumor sample available suitable for sequencing, Eastern Cooperative Oncology Group (ECOG) Performance Status 0 or 1 and patients with normal organ and marrow function reported at screening.About melanomaMelanoma, the most serious form of skin cancer, is characterized by the uncontrolled growth of pigment-producing cells. The rates of melanoma have been rising over the past few decades, with more than 330,000 new cases diagnosed worldwide in 2022. In the U.S., skin cancer is one of the most common types of cancer diagnosed, and melanoma accounts for a large majority of skin cancer deaths. It is estimated there will be about 112,000 new cases of melanoma diagnosed and over 8,500 deaths resulting from the disease in the U.S. in 2026.About KEYTRUDA® (pembrolizumab) injection for intravenous use, 100 mgKEYTRUDA is an anti-programmed death receptor-1 (PD-1) therapy that works by increasing the ability of the body's immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.Merck has the industry's largest immuno-oncology clinical research program. There are currently more than 2,800 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient's likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.Selected KEYTRUDA® (pembrolizumab) Indications in the U.S.MelanomaKEYTRUDA is indicated for the treatment of patients with unresectable or metastatic melanoma.KEYTRUDA is indicated for the adjuvant treatment of adult and pediatric (12 years and older) patients with Stage IIB, IIC, or III melanoma following complete resection.See additional selected KEYTRUDA indications in the U.S. after the Selected Important Safety Information.Selected Important Safety Information for KEYTRUDASevere and Fatal Immune-Mediated Adverse ReactionsKEYTRUDA is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death receptor-1 (PD-1) or the programmed death ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, can affect more than one body system simultaneously, and can occur at any time after starting treatment or after discontinuation of treatment. Important immune-mediated adverse reactions listed here may not include all possible severe and fatal immune-mediated adverse reactions.Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Early identification and management are essential to ensure safe use of anti-PD-1/PD-L1 treatments. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. For patients with TNBC treated with KEYTRUDA in the neoadjuvant setting, monitor blood cortisol at baseline, prior to surgery, and as clinically indicated. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.Withhold or permanently discontinue KEYTRUDA depending on severity of the immune-mediated adverse reaction. In general, if KEYTRUDA requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose adverse reactions are not controlled with corticosteroid therapy.Immune-Mediated PneumonitisKEYTRUDA can cause immune-mediated pneumonitis. The incidence is higher in patients who have received prior thoracic radiation. Immune-mediated pneumonitis occurred in 3.4% (94/2799) of patients receiving KEYTRUDA, including fatal (0.1%), Grade 4 (0.3%), Grade 3 (0.9%), and Grade 2 (1.3%) reactions. Systemic corticosteroids were required in 67% (63/94) of patients. Pneumonitis led to permanent discontinuation of KEYTRUDA in 1.3% (36) and withholding in 0.9% (26) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Pneumonitis resolved in 59% of the 94 patients.Pneumonitis occurred in 8% (31/389) of adult patients with cHL receiving KEYTRUDA as a single agent, including Grades 3-4 in 2.3% of patients. Patients received high-dose corticosteroids for a median duration of 10 days (range: 2 days to 53 months). Pneumonitis rates were similar in patients with and without prior thoracic radiation. Pneumonitis led to discontinuation of KEYTRUDA in 5.4% (21) of patients. Of the patients who developed pneumonitis, 42% interrupted KEYTRUDA, 68% discontinued KEYTRUDA, and 77% had resolution.Pneumonitis occurred in 7% (41/580) of adult patients with resected NSCLC who received KEYTRUDA as a single agent for adjuvant treatment of NSCLC, including fatal (0.2%), Grade 4 (0.3%), and Grade 3 (1%) adverse reactions. Patients received high-dose corticosteroids for a median duration of 10 days (range: 1 day to 2.3 months). Pneumonitis led to discontinuation of KEYTRUDA in 26 (4.5%) of patients. Of the patients who developed pneumonitis, 54% interrupted KEYTRUDA, 63% discontinued KEYTRUDA, and 71% had resolution.Immune-Mediated ColitisKEYTRUDA can cause immune-mediated colitis, which may present with diarrhea. Cytomegalovirus infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Immune-mediated colitis occurred in 1.7% (48/2799) of patients receiving KEYTRUDA, including Grade 4 (

FDA Grants Breakthrough Therapy Designation for Calderasib (MK-1084), an Investigational KRAS G12C Inhibitor, for Certain Patients with Newly Diagnosed Metastatic KRAS G12C-Mutant Non-Small Cell Lung Cancer (NSCLC)May 29, 2026 6:45 AM
Business Wire First Breakthrough Therapy designation for calderasib, supported by positive data from the Phase 1 KANDLELIT-001 trial Calderasib is an investigational, highly potent and specific next-generation KRAS G12C covalent inhibitor Merck (NYSE: MRK), known as MSD outside of the United States and Canada, announced that calderasib (MK-1084), an investigational oral specific KRAS G12C inhibitor, in combination with KEYTRUDA® (pembrolizumab), Merck’s anti-PD-1 therapy, has been granted Breakthrough Therapy designation by the U.S. Food and Drug Administration (FDA) for the first-line treatment of patients with advanced or metastatic non-small cell lung cancer (NSCLC) with KRAS G12C-mutation and expressing PD-L1 (tumor proportion score [TPS] ≥1%). This is the first Breakthrough Therapy designation for calderasib and was supported by positive data from the Phase 1 KANDLELIT-001 trial. “As our understanding of cancer biology and precision medicine continues to advance, we’re encouraged by the potential of new approaches, like calderasib, to help address the underlying drivers of cancer growth,” said Dr. Shweta Jain, vice president, global clinical development, Merck Research Laboratories. “The Breakthrough Therapy designation for calderasib underscores the promising potential of this medicine and unmet need for certain patients with KRAS G12C-mutated NSCLC.” The KRAS G12C mutation is the most frequently observed KRAS mutation in patients, occurring in approximately 14% of patients with NSCLC (adenocarcinoma). The FDA’s Breakthrough Therapy designation is granted to expedite the development and review of medicines that are intended to treat serious or life-threatening conditions. To qualify for this designation, preliminary clinical evidence must indicate that the product may demonstrate substantial improvement on a clinically significant endpoint(s) over available therapies. The benefits of this Breakthrough Therapy designation include more intensive guidance from the FDA on an efficient development program, organizational commitment involving senior managers and experienced review staff, rolling review and potential eligibility for Priority Review. The KANDLELIT clinical development program for calderasib includes five Phase 3 trials across a range of tumor types and stages, including: KANDLELIT-004, evaluating calderasib in combination with KEYTRUDA for patients with newly diagnosed metastatic NSCLC with KRAS G12C-mutation and PD-L1 TPS ≥50%. KANDLELIT-007, evaluating calderasib in combination with KEYTRUDA QLEX (pembrolizumab and berahyaluronidase alfa-pmph) in patients with newly diagnosed advanced or metastatic nonsquamous NSCLC with KRAS G12C-mutation, regardless of PD-L1 expression. KANDLELIT-012, evaluating calderasib in combination with cetuximab and mFOLFOX6 for the first-line treatment of certain patients with locally advanced unresectable or metastatic CRC who have KRAS G12C-mutated tumors. KANDLELIT-013, evaluating calderasib in combination with KEYTRUDA QLEX for certain patients with locally advanced KRAS G12C-mutated NSCLC following receipt of either neoadjuvant KEYTRUDA plus chemotherapy or adjuvant chemotherapy. KANDLELIT-015, evaluating calderasib in combination with durvalumab in certain patients with locally advanced, KRAS G12C-mutated NSCLC after chemotherapy and radiation therapy. Calderasib is being developed through a collaboration with Taiho Pharmaceutical Co. Ltd. and Astex Pharmaceuticals (UK), a wholly owned subsidiary of Otsuka Pharmaceutical Co., Ltd. This collaboration was announced in January 2020. About calderasib
Calderasib (MK-1084) is an investigational, highly potent and specific next-generation KRAS G12C covalent inhibitor. Mutations in KRAS are among the most prevalent mutations found in cancer, occurring with high frequency in non-small cell lung cancer (NSCLC), pancreatic, urogenital and colorectal cancers. The KRAS G12C mutation is the most frequently observed KRAS mutation in patients, occurring in approximately 14% of patients with NSCLC (adenocarcinoma). Despite decades of research and recognition of the therapeutic importance of targeting KRAS, the development of small molecule inhibitors targeting KRAS mutations has been challenging. About lung cancer
Lung cancer is the leading cause of cancer death worldwide. In 2022 alone, there were approximately 2.4 million new cases and 1.8 million deaths from lung cancer globally. Non-small cell lung cancer is the most common type of lung cancer, accounting for about 80% of all cases. In 2025, the overall five-year survival rate for patients diagnosed with lung cancer was nearly 30% in the United States. Improved survival rates are due, in part, to earlier detection and screening, reduction in smoking, advances in diagnostic and surgical procedures, as well as the introduction of new therapies. Early detection and screening remain an important unmet need, as 43% of lung cancer cases are not found until they are advanced. About KEYTRUDA® (pembrolizumab) injection for intravenous use, 100 mg
KEYTRUDA is an anti-programmed death receptor-1 (PD-1) therapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells. Merck has the industry’s largest immuno-oncology clinical research program. There are currently more than 2,800 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient's likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers. About KEYTRUDA QLEX™ (pembrolizumab and berahyaluronidase alfa-pmph) injection for subcutaneous use, 165 mg + 2,000 units/mL
KEYTRUDA QLEX is a fixed-combination drug product of pembrolizumab and berahyaluronidase alfa. Pembrolizumab is a programmed death receptor-1 (PD-1) blocking antibody and berahyaluronidase alfa enhances dispersion and permeability to enable subcutaneous administration of pembrolizumab. KEYTRUDA QLEX is administered as a subcutaneous injection into the thigh or abdomen, avoiding the 5 cm area around the navel, over one minute every three weeks (2.4 mL) or over two minutes every six weeks (4.8 mL). Selected KEYTRUDA® (pembrolizumab) and KEYTRUDA QLEX™ (pembrolizumab and berahyaluronidase alfa-pmph) Indications in the U.S. Non-Small Cell Lung Cancer KEYTRUDA and KEYTRUDA QLEX are each indicated, in combination with pemetrexed and platinum chemotherapy, for the first-line treatment of adult patients with metastatic nonsquamous non–small cell lung cancer (NSCLC), with no EGFR or ALK genomic tumor aberrations. KEYTRUDA and KEYTRUDA QLEX are each indicated, in combination with carboplatin and either paclitaxel or paclitaxel protein-bound, for the first-line treatment of adult patients with metastatic squamous NSCLC. KEYTRUDA and KEYTRUDA QLEX, as single agents, are each indicated for the first-line treatment of adult patients with NSCLC expressing PD-L1 [tumor proportion score (TPS) ≥1%] as determined by an FDA-authorized test, with no EGFR or ALK genomic tumor aberrations, and is: stage III where patients are not candidates for surgical resection or definitive chemoradiation, or metastatic. KEYTRUDA and KEYTRUDA QLEX, as single agents, are each indicated for the treatment of adult patients with metastatic NSCLC whose tumors express PD-L1 (TPS ≥1%) as determined by an FDA-authorized test, with disease progression on or after platinum-containing chemotherapy. Patients with EGFR or ALK genomic tumor aberrations should have disease progression on FDA-approved therapy for these aberrations prior to receiving KEYTRUDA or KEYTRUDA QLEX. KEYTRUDA and KEYTRUDA QLEX are each indicated for the treatment of adult patients with resectable (tumors ≥4 cm or node positive) NSCLC in combination with platinum containing chemotherapy as neoadjuvant treatment, and then continued as a single agent as adjuvant treatment after surgery. KEYTRUDA and KEYTRUDA QLEX, as single agents, are each indicated as adjuvant treatment following resection and platinum-based chemotherapy for adult patients with stage IB (T2a ≥4 cm), II, or IIIA NSCLC. Colorectal Cancer KEYTRUDA and KEYTRUDA QLEX are each indicated for the treatment of adult patients with unresectable or metastatic MSI-H or dMMR colorectal cancer (CRC) as determined by an FDA-authorized test. See additional selected KEYTRUDA indications in the U.S. after the Selected Important Safety Information. Selected Safety Information for KEYTRUDA and KEYTRUDA QLEX Contraindications KEYTRUDA QLEX is contraindicated in patients with known hypersensitivity to berahyaluronidase alfa, hyaluronidase or to any of its excipients. Severe and Fatal Immune-Mediated Adverse Reactions KEYTRUDA and KEYTRUDA QLEX are monoclonal antibodies that belong to a class of drugs that bind to either the programmed death receptor-1 (PD-1) or the programmed death ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, can affect more than one body system simultaneously, and can occur at any time after starting treatment or after discontinuation of treatment. Important immune-mediated adverse reactions listed here may not include all possible severe and fatal immune-mediated adverse reactions. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Early identification and management are essential to ensure safe use of anti–PD-1/PD-L1 treatments. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. For patients with TNBC treated with KEYTRUDA or KEYTRUDA QLEX in the neoadjuvant setting, monitor blood cortisol at baseline, prior to surgery, and as clinically indicated. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate. Withhold or permanently discontinue KEYTRUDA and KEYTRUDA QLEX depending on severity of the immune-mediated adverse reaction. In general, if KEYTRUDA and KEYTRUDA QLEX require interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose adverse reactions are not controlled with corticosteroid therapy. Immune-Mediated Pneumonitis KEYTRUDA and KEYTRUDA QLEX can cause immune-mediated pneumonitis. The incidence is higher in patients who have received prior thoracic radiation. Immune-mediated pneumonitis occurred in 3.4% (94/2799) of patients receiving KEYTRUDA, including fatal (0.1%), Grade 4 (0.3%), Grade 3 (0.9%), and Grade 2 (1.3%) reactions. Systemic corticosteroids were required in 67% (63/94) of patients. Pneumonitis led to permanent discontinuation of KEYTRUDA in 1.3% (36) and withholding in 0.9% (26) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Pneumonitis resolved in 59% of the 94 patients. Immune-mediated pneumonitis occurred in 5% (13/251) of patients receiving KEYTRUDA QLEX in combination with chemotherapy, including fatal (0.4%), Grade 3 (2%), and Grade 2 (1.2%) adverse reactions. Pneumonitis occurred in 7% (41/580) of adult patients with resected NSCLC who received KEYTRUDA as a single agent for adjuvant treatment of NSCLC, including fatal (0.2%), Grade 4 (0.3%), and Grade 3 (1%) adverse reactions. Patients received high-dose corticosteroids for a median duration of 10 days (range: 1 day to 2.3 months). Pneumonitis led to discontinuation of KEYTRUDA in 26 (4.5%) of patients. Of the patients who developed pneumonitis, 54% interrupted KEYTRUDA, 63% discontinued KEYTRUDA, and 71% had resolution. Immune-Mediated Colitis KEYTRUDA and KEYTRUDA QLEX can cause immune-mediated colitis, which may present with diarrhea. Cytomegalovirus infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Immune-mediated colitis occurred in 1.7% (48/2799) of patients receiving KEYTRUDA, including Grade 4 (

Merck Receives Positive EU CHMP Opinion for KEYTRUDA® (pembrolizumab) Plus Padcev® (enfortumab vedotin-ejfv) as Perioperative Treatment for Adults With Cisplatin-Ineligible Resectable Muscle-Invasive Bladder CancerMay 22, 2026 7:55 AM
Business Wire Opinion granted based on positive event-free survival, overall survival and pathologic complete response rate results from the Phase 3 KEYNOTE-905 trial If approved, this combination would become the first and only PD-1 inhibitor plus antibody-drug conjugate regimen for this patient population in the European Union Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today announced the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion recommending approval of KEYTRUDA® (pembrolizumab), Merck’s anti-PD-1 therapy, in combination with Padcev® (enfortumab vedotin-ejfv), an antibody-drug conjugate (ADC), as neoadjuvant treatment and then continued after radical cystectomy as adjuvant treatment, for adults with resectable muscle-invasive bladder cancer (MIBC) who are ineligible for cisplatin-containing chemotherapy. This recommendation, which also includes KEYTRUDA SC® [known as KEYTRUDA QLEX™ (pembrolizumab and berahyaluronidase alfa-pmph) in the U.S.], will now be reviewed by the European Commission (EC) for marketing authorization in the European Union (EU), Iceland, Liechtenstein and Norway, and a final decision is expected by the third quarter of 2026. “Patients in Europe with resectable muscle-invasive bladder cancer who are ineligible for cisplatin-containing chemotherapy have limited treatment options and are at high risk for disease recurrence,” said Dr. Marjorie Green, senior vice president and head of oncology, global clinical development, Merck Research Laboratories. “This positive CHMP recommendation brings us closer to a new chapter of patient care – one that could address this significant unmet need by offering a KEYTRUDA-based regimen both before and after surgery, based on the compelling results from KEYNOTE-905.” The recommendation is based on results from the Phase 3 KEYNOTE-905 trial (also known as EV-303), which was conducted in collaboration with Pfizer and Astellas. In the study, KEYTRUDA plus Padcev, as perioperative treatment, demonstrated statistically significant and clinically meaningful improvements in event-free survival (EFS), overall survival (OS) and pathologic complete response (pCR) rate versus surgery alone in patients with MIBC who are not eligible for or declined cisplatin-based chemotherapy. The KEYTRUDA plus Padcev regimen reduced the risk of EFS events by 60% (HR=0.40 [95% CI, 0.28-0.57]; p

Merck Announces TroFuse-005 Trial Evaluating Sacituzumab Tirumotecan (Sac-TMT) Met Primary Endpoints of Overall Survival (OS) and Progression-Free Survival (PFS) in Certain Patients With Advanced or Recurrent Endometrial CancerMay 18, 2026 6:45 AM
Business Wire Sac-TMT is the first TROP2 ADC to improve OS and PFS compared to chemotherapy in patients with advanced or recurrent endometrial cancer who have progressed after platinum-based chemotherapy and anti-PD-1/L1 immunotherapy in a global Phase 3 study Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today announced the pivotal Phase 3 TroFuse-005 trial evaluating sacituzumab tirumotecan (sac-TMT), an investigational TROP2-directed antibody-drug conjugate (ADC) being developed in collaboration with Kelun-Biotech, met its primary endpoints of overall survival (OS) and progression-free survival (PFS) in certain patients with advanced or recurrent endometrial cancer. TroFuse-005 is the first global Phase 3 trial to demonstrate statistically significant improvement in both OS and PFS compared to chemotherapy for these patients and the first and only ADC to do so for patients with endometrial cancer in this setting. At a pre-specified interim analysis, sac-TMT demonstrated a statistically significant and clinically meaningful improvement in OS and PFS compared to treatment of physician’s choice (TPC, consisting of doxorubicin or paclitaxel) for patients with endometrial cancer who have previously received platinum-based chemotherapy and anti-PD-1/L1 immunotherapy either together or separately. The study also reached its key secondary endpoint of objective response rate. These data will be presented at an upcoming medical meeting and discussed with regulatory authorities worldwide. The safety profile was consistent with what has been observed in previously reported studies of sac-TMT; no new safety signals were observed. “These results show sac-TMT may be able to address a critical unmet need for certain patients with advanced endometrial cancer, one of the only cancers increasing in both incidence and mortality worldwide,” said Dr. Domenica Lorusso, the study’s global lead investigator, lead investigator for ENGOT and professor of Obstetrics and Gynecology at Humanitas University and Humanitas San Pio X, Milan. “Despite recent advances, patients whose disease progresses following treatment with platinum and immunotherapy are urgently in need of new options, and these findings show for the first time that a TROP2 ADC may be an effective option in this setting.” “The scale and ambition of our expansive TroFuse program reflects our deep commitment to advancing one of the industry’s leading ADC pipelines to make a difference for more people facing cancer and builds on our legacy of leadership in gynecologic cancer research,” said Dr. Dean Y. Li, president, Merck Research Laboratories. “These findings reinforce our belief that sac-TMT, with its proprietary bifunctional linker designed with the intent to maximize payload delivery to tumors while minimizing impact on healthy cells in the body, has the potential to become a cornerstone in the treatment of certain patients with advanced endometrial cancer. We thank the patients and investigators for participating in our studies as well as our collaborators at Kelun-Biotech for helping us advance this important treatment.” TroFuse-005 also marks the first positive Phase 3 results from Merck’s TroFuse clinical development program for sac-TMT. The program currently consists of 17 ongoing global Phase 3 trials across multiple tumor types, the broadest range of disease and treatment settings compared to any TROP2-directed ADC to date, including 10 Phase 3 trials in women’s cancers. The program is evaluating sac-TMT across a diverse range of tumor types, including endometrial, bladder, breast, cervical, gastric, non-small cell lung and ovarian cancers, and it spans early-to-late-stage disease as both monotherapy and in combination with immunotherapies. This includes the ongoing TroFuse-033 trial in first line mismatch repair proficient endometrial cancer. About TroFuse-005 TroFuse-005 is a randomized, active-controlled, open-label, multicenter, global Phase 3 trial (ClinicalTrials.gov, NCT06132958) evaluating sac-TMT versus TPC in patients with endometrial carcinoma and carcinosarcoma who have received prior platinum-based chemotherapy and anti-PD-1/anti-PD-L1 immunotherapy either together or separately. The trial enrolled 776 patients who were randomized to receive either sac-TMT or TPC, consisting of doxorubicin or paclitaxel. Sac-TMT (4 mg/kg) was administered on Day 1 of each two-week treatment cycle. Doxorubicin (60 mg/m²) was administered on Day 1 of each three-week treatment cycle and paclitaxel (80 mg/m²) was administered on Days 1, 8 and 15 of each four-week treatment cycle. The study has dual primary endpoints: PFS by blinded independent central review (BICR), defined as the time from randomization to the first documented disease progression or death from any cause, and OS, defined as the time from randomization to death from any cause. A key secondary endpoint is objective response rate, and other secondary endpoints include duration of response, incidence of adverse events, treatment discontinuation due to adverse events and change from baseline in global health status/quality-of-life scores. About sacituzumab tirumotecan (sac-TMT) Sac-TMT is an investigational TROP2-directed ADC with a belotecan-derived topoisomerase I inhibitor payload and a bifunctional linker designed with the potential to maximize payload delivery to tumor cells and minimize payload loss while circulating in the body. Sac-TMT is the only TROP2 ADC designed with a focus on both ends of the linker. TROP2 is overexpressed on tumor cells compared to healthy cells in many common cancers, and through the TroFuse clinical development program, Merck is evaluating sac-TMT in 17 ongoing global Phase 3 trials across multiple tumor types, the broadest range of disease and treatment settings compared to any TROP2-directed ADC to date. The TroFuse development program spans early-to-late-stage disease in more than nine disease areas and includes more than 15,000 patients worldwide. Numerous Phase 3 trials are exploring sac-TMT as monotherapy and in combination with immunotherapies, aiming to improve survival and quality of life for patients with advanced and earlier-stage cancers. About endometrial cancer Endometrial cancer (also referred to as endometrial carcinoma) begins in the inner lining of the uterus, which is known as the endometrium, and is the most common type of cancer in the uterus. More than 90% of uterine body cancers occur in the endometrium. In the U.S., it is estimated there will be approximately 68,270 patients diagnosed with endometrial cancer and approximately 14,450 patient deaths from the disease in 2026. Globally, endometrial cancer is the sixth most common cancer in women and the 15th most common cancer overall. Following primary treatment, patients face a risk of their cancer returning, often as distant metastasis, which is associated with poorer outcomes. About Merck’s research in women’s cancers Merck is advancing research aimed at expanding treatment options for certain breast and gynecologic (ovarian, cervical and endometrial) cancers, with a goal of improving outcomes for more patients affected by these diseases. Breast cancer and gynecologic cancers are the first and second most commonly occurring cancer types among women worldwide, respectively, and Merck aims to provide options to patients facing these devastating diseases. With more than 20 clinical trials in nearly 20,000 patients around the world, Merck is driving innovative research to purposefully advance standards of care in women’s cancers. Merck’s research efforts include trials focused on evaluating its medicines in earlier stages, as well as identifying novel mechanisms and new combinations with these treatments.

Next-Generation GLP-1 Innovation Could Unlock Massive Metabolic Healthcare Market OpportunitiesMay 13, 2026 9:00 AM
InvestorsHub NewsWireNext-Generation GLP-1 Innovation Could Unlock Massive Metabolic Healthcare Market OpportunitiesBioMedWire Editorial Coverage: Obesity and type 2 diabetes mellitus ("T2DM") rank among the most urgent and costly healthcare problems facing the world today, contributing to surging rates of cardiovascular disease, fatty liver disease, kidney complications and ballooning healthcare expenses. What once represented a specialized class of diabetes treatments has grown into one of the most consequential therapeutic categories in modern medicine, with GLP-1 receptor agonists now fundamentally restructuring how obesity, metabolic disease and potentially even neurodegeneration are treated. Operating in this environment is SureNano Science Ltd. (CSE: SURE) (OTCQB: SURNF) (Profile), which through its subsidiary GlucaPharm Inc. is developing a distinct next-generation GLP-1 platform built around GEP-44, a novel triple agonist peptide engineered to improve efficacy, tolerability, and delivery flexibility within one of the most commercially dynamic pharmaceutical markets in history. SureNano is one of the emerging microcap companies active in the GLP-1 space, operating alongside established leaders including Merck & Co. Inc. (NYSE: MRK), AbbVie Inc. (NYSE: ABBV), Viking Therapeutics Inc. (NASDAQ: VKTX) and Altimmune Inc. (NASDAQ: ALT).SureNano Science is developing GEP-44 as a patented next-generation metabolic therapy designed to address the limitations of first-generation GLP-1 drugs.The commercial potential tied to GLP-1 therapies is expanding quickly, with the global GLP-1 market forecast to potentially reach $190 billion by 2035.SureNano Science is also eyeing differentiated drug-delivery technologies designed to improve patient accessibility and long-term adherence.Preclinical data from SureNano Science suggest that GEP-44 may offer substantive differentiation relative to earlier-generation GLP therapies.Beyond its primary GLP-1 metabolic platform, SureNano Science is also evaluating early-stage opportunities that could expand the long-term scope of its therapeutic and delivery technology portfolio.Click here to view the custom infographic of the SureNano Science editorial. Rewriting the Rules of Metabolic MedicineThe global obesity crisis shows no sign of plateauing. According to the World Health Organization ("WHO"), a reported one billion people globally are currently living with obesity, while type 2 diabetes rates continue to climb across both high-income and developing economies. The WHO further notes that obesity increases the risk of cardiovascular disease, stroke and T2DM, while further research has linked obesity to chronic kidney disease and rising healthcare expenditures, placing substantial and growing pressure on health systems around the world.GLP-1 receptor agonists have rapidly risen to become one of the defining breakthroughs in metabolic medicine. Originally introduced to manage blood glucose levels in diabetes patients, these drugs are now recognized for their capacity to drive meaningful weight reduction and deliver broad improvements in metabolic health. Market leaders Novo Nordisk A/S and Eli Lilly and Company have come to dominate the space through their blockbuster injectable franchises, including Ozempic(R), Wegovy(R), Mounjaro(R) and Zepbound(R).Commercial momentum in this space is increasing. JPMorgan Chase & Co. forecasts that the general obesity drug market could reach $200 billion by 2030 as global adoption expands and indications stretch beyond diabetes and weight management. Additional industry projections suggest GLP-1 therapies are on track to become one of the most commercially successful drug categories ever, with annual sales projections of $150 billion or more by the end of the decade.The industry is already pivoting toward the next generation of incretin therapies, with a focus on improved efficacy, tolerability and patient convenience. Needle-free, including oral, formulas, expanded indications and combination metabolic approaches have emerged as major priorities across the sector. SureNano Science is positioning itself in this scenario as a nimble participant pursuing differentiated innovation through GEP-44, a patented triple agonist peptide licensed from Syracuse University and designed to advance through the U.S. Food and Drug Administration ("FDA") regulatory route.A Next-Gen Candidate Built for Better OutcomesSureNano Science is developing GEP-44 as a patented next-generation metabolic therapy designed to address the limitations of first-generation GLP-1 drugs, positioning this up-and-coming microcap as a small but strategically focused company moving through the FDA process. Unlike traditional GLP-1 agonists, which act on a single receptor pathway, GEP-44 functions as a triple agonist targeting GLP-1 alongside peptide YY receptors Y1 and Y2. This combined mechanism is designed to simultaneously regulate glucose metabolism, reduce appetite and improve tolerability within a single therapeutic molecule.The compound originated at Syracuse University and has generated promising results in preclinical settings. According to research, GEP-44 produced meaningful reductions in food intake and decreased body weight while also enhancing glycemic control in preclinical models. In addition, the compound did not trigger the nausea, malaise and gastrointestinal adverse effects commonly seen with many first-generation GLP-1 therapies, a distinction that could become increasingly significant as patient populations and adherence demands grow.The broader pharmaceutical industry is investing aggressively in incretin therapies that can address tolerability and long-term adherence challenges. PwC reports that the next segment of the obesity drug market will most likely be characterized by expanded indications, more patient-friendly delivery formats and therapies with stronger adherence profiles. This lends itself to a supportive environment for companies pursuing second-generation GLP innovation.Despite being smaller than more-established pharmaceutical players, SureNano Science operates with a lean development model and cost-efficient structure built for flexibility and development speed. The company is involved in substantial research in Australia, where government incentive programs may provide research tax credits of up to 43.5% on qualifying expenditures. Should GEP-44 continue producing favorable results through clinical development, the company could emerge as an attractive acquisition, licensing or partnership candidate within the fast-expanding GLP ecosystem.Market Scale and the Commercial Case for GLP-1 InnovationThe commercial potential tied to GLP-1 therapies is expanding quickly. According to Morgan Stanley, the global GLP-1 market could reach $190 billion by 2035 as patient adoption broadens and therapeutic applications extend into new disease areas. Industry forecasts from BCC Research also forecast significant long-term growth, with the GLP-1 analogue market estimated to reach $268.4 billion by 2030.Patient uptake estimates that between 25 and 30 million Americans could be using GLP-1 therapies by 2030, up from approximately 10 million in 2026. Increasing insurance coverage along with obesity prevalence and growing physician familiarity are all driving the rapid mainstreaming of these treatments.At the same time, the competitive setting is shifting toward the next wave of products. IQVIA calls 2026 the "year of the orals," with oral GLP-1 formulations projected to meaningfully enhance accessibility, compliance and long-term maintenance therapy adoption. The anticipated off-patent expansion of semaglutide across major global markets is also expected to intensify competition while broadening overall patient access.As GEP-44 advances through IND-enabling studies and moves toward eventual phase 1 trials, SureNano Science stands as one of a small number of microcap public companies offering direct exposure to the expanding GLP-1 market. This positioning may represent a meaningful valuation gap relative to large-cap pharmaceutical incumbents and late-stage obesity therapy developers, particularly if the company achieves key clinical and regulatory milestones.Delivery Innovation as a Second Engine of ValueAlongside its core therapeutic development efforts, SureNano Science is also eyeing differentiated drug-delivery technologies designed to improve patient accessibility and long-term adherence. The company's platform strategy includes evaluating oral, sublingual and intranasal delivery approaches that could eventually reduce reliance on injectable administration.Convenience and adherence have emerged as increasingly important competitive dimensions within the GLP-1 market. The dominant therapies today are injection-based, creating barriers for some patients due to administration complexity, refrigeration requirements and long-term compliance challenges. Noninvasive and oral alternatives are widely regarded as representing one of the most significant near-term commercial opportunities in obesity and diabetes treatment.Industry analysts increasingly view delivery innovation as potentially as consequential as efficacy improvements. IQVIA notes that oral obesity therapies could substantially boost long-term maintenance adoption while simplifying supply chains by removing cold-chain requirements, factors that could meaningfully expand patient access in international markets.By combining therapeutic development with delivery innovation, SureNano Science is working to build a vertically integrated metabolic disease platform rather than advancing a single injectable drug candidate. This broader strategy may generate additional long-term optionality and commercial flexibility as the obesity treatment market continues to evolve.Preclinical Data Point to a Meaningful Competitive EdgePreclinical data from SureNano Science suggest that GEP-44 may offer substantive differentiation relative to earlier-generation GLP therapies. According to the company, the compound demonstrated approximately 15% weight loss in preclinical testing, compared with roughly 9% observed with liraglutide, while food intake reductions reached approximately 39% versus around 20% for the comparator.In addition to weight reduction, GEP-44 produced improvements in glycemic control while reportedly avoiding nausea and vomiting during testing. Gastrointestinal side effects remain among the most frequently cited challenges associated with currently marketed GLP-1 therapies and represent a significant driver of discontinuation. Improved tolerability could therefore become a meaningful competitive advantage if these preclinical findings are validated in human studies.The pharmaceutical industry continues to pour resources into next-generation obesity therapies capable of delivering better outcomes and patient experiences. The Pharma Letter reports that obesity drug pipelines are increasingly oriented toward differentiation through combination receptor pathways, improved tolerability profiles, and expanded delivery options as the competitive field intensifies.While GEP-44 remains in preclinical development, these early findings place SureNano Science within a strategically important segment of the obesity treatment landscape. If subsequent studies continue to support these results, the company could establish itself as a distinctive participant in one of the largest and most rapidly expanding therapeutic categories in contemporary healthcare.Exploring Broader Platform Opportunities for Long-Term GrowthBeyond its primary GLP-1 metabolic platform, SureNano Science is also evaluating early-stage opportunities that could expand the long-term scope of its therapeutic and delivery technology portfolio. These discussions include nonbinding opportunities involving ibogaine-related intellectual property concentrated on formulation and delivery technologies.While still exploratory and not considered a core asset at this stage, the initiative reflects a broader strategic aim of building diversified platform capabilities across multiple high-growth therapeutic areas. Scientific and investor interest in ibogaine and related psychedelic-derived therapeutics has grown considerably in recent years, as researchers examine their potential applications in addiction treatment, mental health conditions, and neurological disorders.CNN recently reported on the growing scientific and regulatory attention being directed at ibogaine research, particularly in areas related to opioid addiction and treatment-resistant mental health conditions. The U.S. Food and Drug Administration has also signaled increasing openness to accelerating development pathways for treatments targeting serious mental illnesses and areas of significant unmet medical need.SureNano's interest in formulation and delivery technologies within these emerging areas fits naturally with the company's broader emphasis on drug-delivery innovation and platform versatility. Rather than treating ibogaine-related opportunities as a standalone commercial priority, the company appears to be assessing how specialized delivery technologies and intellectual property could complement its existing capabilities in metabolic therapeutics and nontraditional administration. This kind of optionality may provide incremental long-term strategic value if the regulatory landscape surrounding psychedelic-based therapies continues to evolve.These initiatives remain early stage and are subject to meaningful scientific, clinical and regulatory uncertainty. However, by selectively evaluating expansion opportunities alongside its primary GLP-1 development program, SureNano Science is aligning itself with a broader trend toward diversified therapeutic platforms capable of competing across multiple large and evolving healthcare markets. As pharmaceutical innovation increasingly converges around metabolic health, neuroscience, and advanced delivery technologies, strategic flexibility may prove to be a growing differentiator for emerging biotechnology companies.Advances Continue Across the GLP-1 LandscapeMomentum across the GLP-1 and metabolic disease sector continues to accelerate as leading biotechnology and pharmaceutical companies expand development programs targeting obesity, diabetes, liver disease and broader cardiometabolic conditions. Recent news from the GLP-1 space highlights continued investment in next-generation therapies, late-stage clinical development, strategic partnerships and regulatory progress as the rapidly evolving space remains one of the most closely watched areas in healthcare and biotechnology.Merck & Co. Inc. (NYSE: MRK) expanded into the GLP-1 and obesity-treatment market through an exclusive global licensing agreement with Hansoh Pharma for an investigational oral GLP-1 receptor agonist. Merck stated that the candidate is being developed for cardiometabolic diseases and described the agreement as part of the company's strategy to strengthen its presence in metabolic disorders. The company noted that it will receive exclusive rights outside China to develop, manufacture and commercialize the therapy, reflecting a growing industry focus on oral GLP-1 treatments for obesity and related conditions.AbbVie Inc. (NYSE: ABBV) announced positive topline results from a phase 1 multiple ascending dose study evaluating ABBV-295, its long-acting amylin analog being developed for obesity and metabolic disease treatment. AbbVie reported that ABBV-295 demonstrated "clinically meaningful" body weight reduction ranging from approximately 7.75% to 9.79% over the treatment period, while also showing a "favorable tolerability profile" with no serious adverse events reported. The company emphasized that the data support continued advancement of its metabolic disease pipeline amid increasing interest in next-generation obesity therapies that may complement or compete with GLP-1 drugs.Viking Therapeutics Inc. (NASDAQ: VKTX) reported completion of enrollment in its phase 3 VANQUISH-2 trial evaluating VK2735, its dual GLP-1/GIP receptor agonist candidate for obesity treatment. Viking stated that the study is assessing subcutaneous VK2735 in adults with obesity and type 2 diabetes, while concurrent phase 3 development is also ongoing in broader obesity populations. The company noted that VK2735 is being developed in both oral and injectable formulations for metabolic disorders, underscoring its position in the rapidly expanding GLP-1 obesity-treatment landscape.Altimmune Inc. (NASDAQ: ALT) announced that pemvidutide received FDA Breakthrough Therapy designation for the treatment of MASH, further advancing development of the company's GLP-1/glucagon dual receptor agonist platform. Altimmune stated that pemvidutide has demonstrated improvements in liver fat reduction, weight loss and fibrosis-related measures, while the company plans to initiate a Phase 3 trial evaluating multiple doses over a 52-week treatment period. The announcement reinforces Altimmune's ongoing efforts to position pemvidutide within the broader GLP-1 and metabolic disease sector spanning obesity, liver disease and related cardiometabolic conditions.Collectively, these developments underscore the growing importance of GLP-1-related therapies as companies compete to address some of the world's largest and fastest-growing chronic health challenges. With ongoing advances in oral formulations, combination therapies and expanded metabolic disease applications, the sector continues to attract significant scientific, clinical and investor attention while reshaping the future landscape of obesity and cardiometabolic treatment.For further information about SureNano Science Ltd., visit the SureNano Science profile.About BioMedWireBioMedWire ("BMW") is a specialized communications platform with a focus on the latest developments in the Biotechnology (BioTech), Biomedical Sciences (BioMed) and Life Sciences sectors.

7 In collaboration with Daiichi Sankyo About intismeran autogene (mRNA-4157 or V940) Intismeran autogene is a novel investigational messenger RNA (mRNA)-based individualized neoantigen therapy (INT) consisting of a synthetic mRNA coding for up to 34 neoantigens that is designed and produced based on the unique mutational signature of the DNA sequence of the patient’s tumor. Upon administration into the body, the algorithmically derived and RNA-encoded neoantigen sequences are endogenously translated and undergo natural cellular antigen processing and presentation, a key step in adaptive immunity. Individualized neoantigen therapies are designed to train and activate an antitumor immune response by generating specific T-cell responses based on the unique mutational signature of a patient’s tumor. About sacituzumab tirumotecan (sac-TMT) Sac-TMT is an investigational TROP2-directed ADC with a belotecan-derived topoisomerase I inhibitor payload and a bifunctional linker designed with the potential to maximize payload delivery to tumor cells and minimize payload loss while circulating in the body. Sac-TMT is the only TROP2 ADC designed with a focus on both ends of the linker. TROP2 is overexpressed on tumor cells compared to healthy cells in many common cancers, and through the TroFuse clinical development program, Merck is evaluating sac-TMT in 17 ongoing global Phase 3 trials across multiple tumor types, the broadest range of disease and treatment settings compared to any TROP2-directed ADC to date. The TroFuse development program spans early-to-late-stage disease in more than nine disease areas and includes more than 15,000 patients worldwide. Numerous Phase 3 trials are exploring sac-TMT as monotherapy and in combination with immunotherapies, aiming to improve survival and quality of life for patients with advanced and earlier-stage cancers. About raludotatug deruxtecan (R-DXd) Raludotatug deruxtecan is an investigational, potential first-in-class CDH6 directed ADC. Designed using Daiichi Sankyo’s proprietary DXd ADC Technology, raludotatug deruxtecan is comprised of a humanized anti-CDH6 IgG1 monoclonal antibody attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers. About KEYTRUDA® (pembrolizumab) injection for intravenous use, 100 mg KEYTRUDA is an anti-programmed death receptor-1 (PD-1) therapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells. Merck has the industry’s largest immuno-oncology clinical research program. There are currently more than 2,800 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient's likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.

See additional selected KEYTRUDA indications in the U.S. after the Selected Important Safety Information. Selected Important Safety Information for KEYTRUDA Severe and Fatal Immune-Mediated Adverse Reactions KEYTRUDA is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death receptor-1 (PD-1) or the programmed death ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, can affect more than one body system simultaneously, and can occur at any time after starting treatment or after discontinuation of treatment. Important immune-mediated adverse reactions listed here may not include all possible severe and fatal immune-mediated adverse reactions. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Early identification and management are essential to ensure safe use of anti–PD-1/PD-L1 treatments. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. For patients with TNBC treated with KEYTRUDA in the neoadjuvant setting, monitor blood cortisol at baseline, prior to surgery, and as clinically indicated. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate. Withhold or permanently discontinue KEYTRUDA depending on severity of the immune-mediated adverse reaction. In general, if KEYTRUDA requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose adverse reactions are not controlled with corticosteroid therapy. Immune-Mediated Pneumonitis KEYTRUDA can cause immune-mediated pneumonitis. The incidence is higher in patients who have received prior thoracic radiation. Immune-mediated pneumonitis occurred in 3.4% (94/2799) of patients receiving KEYTRUDA, including fatal (0.1%), Grade 4 (0.3%), Grade 3 (0.9%), and Grade 2 (1.3%) reactions. Systemic corticosteroids were required in 67% (63/94) of patients. Pneumonitis led to permanent discontinuation of KEYTRUDA in 1.3% (36) and withholding in 0.9% (26) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Pneumonitis resolved in 59% of the 94 patients. Pneumonitis occurred in 8% (31/389) of adult patients with cHL receiving KEYTRUDA as a single agent, including Grades 3-4 in 2.3% of patients. Patients received high-dose corticosteroids for a median duration of 10 days (range: 2 days to 53 months). Pneumonitis rates were similar in patients with and without prior thoracic radiation. Pneumonitis led to discontinuation of KEYTRUDA in 5.4% (21) of patients. Of the patients who developed pneumonitis, 42% interrupted KEYTRUDA, 68% discontinued KEYTRUDA, and 77% had resolution. Pneumonitis occurred in 7% (41/580) of adult patients with resected NSCLC who received KEYTRUDA as a single agent for adjuvant treatment of NSCLC, including fatal (0.2%), Grade 4 (0.3%), and Grade 3 (1%) adverse reactions. Patients received high-dose corticosteroids for a median duration of 10 days (range: 1 day to 2.3 months). Pneumonitis led to discontinuation of KEYTRUDA in 26 (4.5%) of patients. Of the patients who developed pneumonitis, 54% interrupted KEYTRUDA, 63% discontinued KEYTRUDA, and 71% had resolution. Immune-Mediated Colitis KEYTRUDA can cause immune-mediated colitis, which may present with diarrhea. Cytomegalovirus infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Immune-mediated colitis occurred in 1.7% (48/2799) of patients receiving KEYTRUDA, including Grade 4 (

Merck Scientists Publish Landmark Paper on Novel Method for Large-Scale Biocatalytic Synthesis of Investigational Oral PCSK9 Inhibitor, Enlicitide DecanoateMay 7, 2026 2:05 PM
Business Wire Publication in Science magazine outlines blueprint for the scalable synthesis of complex orally available macrocyclic peptides Enlicitide, a novel macrocyclic peptide, has the potential to be the first approved oral PCSK9 inhibitor Merck (NYSE: MRK), known as MSD outside the United States and Canada, announced today the publication of work describing the large-scale synthesis of enlicitide decanoate, the company’s investigational oral PCSK9 inhibitor, using a tailored suite of enzymes in the latest issue of the peer reviewed journal Science. “Macrocyclic peptides have the potential to unlock new opportunities to develop oral treatment options for challenging therapeutic targets and broaden patient access,” said Dr. Dean Y. Li, president, Merck Research Laboratories. “The scalable production process for enlicitide described in this publication showcases Merck’s scientific capabilities and underscores our sustained commitment to helping address the global cardiovascular epidemic.” In this publication, Merck scientists detail the biocatalytic assembly of enlicitide using a suite of enzymes that catalyze selective peptide fragment formation, coupling, and macrocyclization. Together with efficient purifications using crystallization, this strategy enabled the manufacture of a product that would not be possible with traditional synthetic methods. The method described offers a sustainable blueprint for the scalable development of complex macrocyclic peptide therapeutics, environmental advantages and manufacturing efficiencies that support efforts to expand patient access. About biocatalysis Biocatalysis describes the process of using enzymes to conduct chemical synthesis. Biocatalysis offers environmental sustainability advantages over chemical catalyst methods. For more than 25 years Merck has invested in the development of biocatalysis including the generation of novel enzymes for the synthesis and novel manufacturing of pharmaceutical products at scale. About macrocyclic peptides Over a decade ago, an interdisciplinary team of Merck scientists were challenged to create a type of medicine that may provide the potency and selectivity of a biologic therapy but in the form of a pill. Macrocyclic peptides are intricate ring-shaped molecules with the ability to target and disrupt protein-protein interactions while retaining oral bioavailability. For more information regarding our approach to macrocyclic peptides, visit merck.com About enlicitide and PCSK9 Enlicitide has the potential to be the first approved oral PCSK9 inhibitor. It is designed to lower LDL-C via the same biological mechanism as currently approved monoclonal antibody, injectable PCSK9 inhibitors but in a daily pill form. Enlicitide is a novel macrocyclic peptide candidate that binds to PCSK9 and inhibits the interaction of PCSK9 with LDL receptors. PCSK9 plays a key role in cholesterol homeostasis by regulating levels of the LDL receptor, which is responsible for the uptake of cholesterol into cells. Inhibition of PCSK9 is designed to prevent the interaction of PCSK9 with LDL receptors. This results in greater numbers of LDL receptors available on the cell surface to remove LDL cholesterol from the blood. About the CV epidemic and atherosclerotic cardiovascular disease The silent CV epidemic is the leading cause of deaths globally, contributing to the majority of heart attacks and strokes, and deaths related to CV continue to rise. ASCVD accounts for 85% of CV deaths. It is caused by the buildup of plaque within the arteries, leading to narrowed or blocked blood vessels that can result in serious CV events such as heart attacks and strokes as well as coronary artery disease, peripheral artery disease and cerebrovascular disease. About Merck At Merck, known as MSD outside of the United States and Canada, we are unified around our purpose: We use the power of leading-edge science to save and improve lives around the world.

For the first quarter of 2026, Generally Accepted Accounting Principles (GAAP) loss / earnings per share (EPS) assuming dilution was a loss per share of $1.72 and non-GAAP loss per share was $1.28. Both the GAAP and non-GAAP loss per share were due to a charge for the acquisition of Cidara Therapeutics, Inc. (Cidara) of $3.62 per share.


Non-GAAP EPS excludes acquisition- and divestiture-related costs and costs related to restructuring programs, as well as income and losses from investments in equity securities.

Decline primarily due to unfavorable impact of revenue-hedging activities and lower revenue from third-party manufacturing arrangements, partially offset by higher milestones received for out-licensing arrangements and higher royalty income.








*Alliance revenue for this product represents the Company’s share of profits, which are product sales net of cost of sales and commercialization costs.








**Other revenues are comprised primarily of revenues from third-party manufacturing arrangements and miscellaneous corporate revenues, including revenue-hedging activities.







In addition, Koselugo alliance revenue was $161 million for the first quarter of 2026 compared with $44 million for the first quarter of 2025. The increase was due to a $150 million payment received in the first quarter of 2026 in connection with an amendment to the collaboration agreement with AstraZeneca in 2025, which (subject to an annual election by AstraZeneca) discontinued the provisions whereby the Company shared revenue and costs with AstraZeneca, and revised the payment structure.

GAAP Expense, EPS and Related Information

Gross margin was 74.2% for the first quarter of 2026 compared with 78.0% for the first quarter of 2025. The decrease was primarily due to higher amortization of intangible assets, higher restructuring costs, the recognition of inventory fair value step-up related to the 2025 Verona Pharma acquisition and the unfavorable impact of foreign exchange, partially offset by favorable product mix.


Selling, general and administrative (SG&A) expenses were $2.7 billion in the first quarter of 2026, an increase of 6% compared with the first quarter of 2025. The increase was primarily due to higher administrative costs and the unfavorable impact of foreign exchange.


Research and development (R&D) expenses were $12.6 billion in the first quarter of 2026 compared with $3.6 billion in the first quarter of 2025. The increase was primarily due to a $9.0 billion charge for the acquisition of Cidara, higher clinical development spending, the unfavorable impact of foreign exchange and restructuring costs, partially offset by a $200 million reduction in R&D expenses as part of the funding agreement with Blackstone Life Sciences (Blackstone) and a $100 million charge in the first quarter of 2025 for the achievement of a developmental milestone related to the 2024 acquisition of EyeBiotech Limited (EyeBio).


Other (income) expense, net, was $138 million of expense in the first quarter of 2026 compared with $35 million of income in the first quarter of 2025. The unfavorability was primarily due to higher net interest expense, partially offset by higher net income from investments in equity securities.


The income tax provision for the first quarter of 2026 was $709 million on a pretax loss of $3.5 billion, resulting in an effective income tax rate of (20.1)%. This effective income tax rate includes a 33.1 percentage point unfavorable impact of the charge for the acquisition of Cidara, for which no tax benefit was recorded.


GAAP loss per share was $1.72 for the first quarter of 2026 compared with earnings per share of $2.01 for the first quarter of 2025, primarily driven by a $3.62 per share charge included in the first quarter of 2026 for the acquisition of Cidara.


Non-GAAP Expense, EPS and Related Information

Non-GAAP gross margin was 81.9% for the first quarter of 2026 compared with 82.2% for the first quarter of 2025. The decrease was primarily due to the unfavorable impact of foreign exchange, partially offset by favorable product mix.


Non-GAAP SG&A expenses were $2.7 billion in the first quarter of 2026, an increase of 5% compared with the first quarter of 2025. The increase was primarily due to higher administrative costs and the unfavorable impact of foreign exchange.


Non-GAAP R&D expenses were $12.6 billion in the first quarter of 2026 compared with $3.6 billion in the first quarter of 2025. The increase was primarily due to a $9.0 billion charge for the acquisition of Cidara, higher clinical development spending and the unfavorable impact of foreign exchange, partially offset by a $200 million reduction in R&D expenses as part of the funding agreement with Blackstone and a $100 million charge in the first quarter of 2025 for the achievement of a developmental milestone related to the 2024 acquisition of EyeBio.


Non-GAAP other (income) expense, net, was $318 million of expense in the first quarter of 2026 compared with $75 million of expense in the first quarter of 2025. The unfavorability was primarily due to higher net interest expense.


The non-GAAP income tax provision for the first quarter of 2026 was $957 million on a pretax loss of $2.2 billion, resulting in a non-GAAP effective income tax rate of (43.5)%. This effective income tax rate includes a 57.6 percentage point unfavorable impact of the charge for the acquisition of Cidara, for which no tax benefit was recorded.


Non-GAAP loss per share was $1.28 for the first quarter of 2026 compared with earnings per share of $2.22 for the first quarter of 2025, primarily driven by a $3.62 per share charge included in the first quarter of 2026 for the acquisition of Cidara.

Pipeline and Portfolio Highlights

In the first quarter, the Company continued to advance its pipeline, achieving significant regulatory and clinical milestones across a broad range of therapeutic areas.



Oncology:


U.S. Food and Drug Administration (FDA) approved KEYTRUDA and KEYTRUDA QLEX plus paclitaxel, with or without bevacizumab, for the treatment of certain adults with PD-L1+ (combined positive score [CPS] ≥1) platinum-resistant ovarian cancer, based on Phase 3 KEYNOTE-B96 trial.


The European Commission (EC) also approved this KEYTRUDA regimen for this population.






In April, FDA approved a label update for KEYTRUDA QLEX based on results from Phase 2 MK-3475A-F11 trial, which evaluated patient-reported preference for subcutaneous administration of KEYTRUDA QLEX over intravenous administration of KEYTRUDA in participants with multiple tumor types.



In April, FDA granted priority review for ifinatamab deruxtecan (I-DXd) for certain adults with previously treated extensive-stage small cell lung cancer, based on Phase 2 Ideate-Lung01 trial. I-DXd is part of the Company’s collaboration with Daiichi Sankyo.


FDA set Prescription Drug User Fee Act (PDUFA) date of Oct. 10, 2026.






FDA accepted for priority review supplemental applications for WELIREG in combination with KEYTRUDA or KEYTRUDA QLEX for the adjuvant treatment of certain patients with RCC, based on the Phase 3 LITESPARK-022 trial.


FDA set PDUFA date of June 19, 2026.






FDA accepted supplemental applications for WELIREG plus Lenvima in certain previously treated patients with advanced RCC, based on the Phase 3 LITESPARK-011 trial. Lenvima is being developed as part of a collaboration with Eisai Co., Ltd (Eisai).


FDA set PDUFA date of Oct. 4, 2026.






Announced positive results from Phase 3 KEYNOTE-B15 trial (also known as EV-304) demonstrating KEYTRUDA plus Padcev reduced the risk of event-free survival (EFS) events by 47% and reduced the risk of death by 35% in cisplatin-eligible patients with muscle-invasive bladder cancer (MIBC) when given before and after surgery.


KEYNOTE-B15 is the sixth study demonstrating overall survival (OS) with a KEYTRUDA-based regimen in an earlier-stage cancer.






In April, FDA granted priority review for KEYTRUDA and KEYTRUDA QLEX, each with Padcev, for cisplatin-eligible patients with MIBC, based on the Phase 3 KEYNOTE-B15 trial.


FDA set PDUFA date of Aug. 17, 2026.






In a pre-specified interim analysis of the Phase 3 LITESPARK-012 study, compared to KEYTRUDA plus Lenvima, the triplet combination therapy of KEYTRUDA plus Lenvima plus WELIREG, as well as the combination of MK-1308A (an investigational fixed dose coformulation of KEYTRUDA and the anti-CTLA-4 antibody quavonlimab) plus Lenvima, did not show a statistically significant improvement in the primary endpoints of progression-free survival and OS in patients with advanced clear cell RCC.



In the Phase 3 KEYNOTE-975 study, compared to placebo plus definitive chemoradiotherapy (dCRT), KEYTRUDA plus dCRT did not show a statistically significant improvement in the primary endpoint of EFS in certain patients with locally advanced unresectable esophageal carcinoma.



In a prespecified interim analysis of the Phase 3 KEYNOTE-866 study, compared to perioperative placebo plus neoadjuvant chemotherapy, perioperative KEYTRUDA plus neoadjuvant chemotherapy did not show a statistically significant improvement in the primary endpoint of EFS in patients with cisplatin-eligible MIBC who underwent radical cystectomy and pelvic lymph node dissection.







Vaccines and Infectious Diseases:


In April, FDA approved once-daily IDVYNSO, an oral, two-drug, single-tablet regimen of doravirine/islatravir (DOR/ISL) for the treatment of certain adults with virologically suppressed HIV-1, based on Phase 3 MK-8591A-051 and MK-8591A-052 trials. IDVYNSO was also approved in Japan for these patients in March.



Presented data from three Phase 3 trials evaluating DOR/ISL at the 33rd Conference on Retroviruses and Opportunistic Infections (CROI), including:


Results from Phase 3 MK-8591A-053 trial demonstrated that DOR/ISL is the first two-drug regimen that does not include an integrase strand transfer inhibitor to demonstrate non-inferiority and similar safety profile at Week 48 versus bictegravir/emtricitabine/tenofovir alafenamide6 [(50 mg/200 mg/25 mg) (BIC/FTC/TAF)] in adults living with HIV-1 who had not previously received antiretroviral treatment.



Results from the Phase 3 MK-8591A-052 and MK-8591A-051 trials demonstrated that DOR/ISL maintained virologic suppression at Week 96 in adults with virologically suppressed HIV-1 who switched from other antiretroviral therapies, including BIC/FTC/TAF.






In April, EC approved ENFLONSIA for the prevention of respiratory syncytial virus (RSV) lower respiratory tract disease in newborns and infants during their first RSV season, based on Phase 2b/3 CLEVER and Phase 3 SMART trials.



Announced positive second RSV season results from Phase 3 SMART trial evaluating the safety, efficacy and pharmacokinetics of ENFLONSIA in infants and children at increased risk for severe RSV disease over two RSV seasons.



European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) adopted positive opinion for an expanded indication for CAPVAXIVE for active immunization against invasive pneumococcal disease and pneumococcal pneumonia in certain children and adolescents at increased risk of pneumococcal disease.







Cardiometabolic and Respiratory:


Presented new data at the American College of Cardiology’s Annual Scientific Session and Expo (ACC.26) including:


Positive results from Phase 3 CORALreef AddOn trial demonstrated significantly greater LDL-C reductions at eight weeks compared to guideline-recommended oral non-statin therapies when added to background statins. This is the third positive Phase 3 study of enlicitide.



Positive data from Phase 2 CADENCE trial provided definitive proof-of-concept for WINREVAIR in adults with the syndrome of combined post- and precapillary pulmonary hypertension and heart failure with preserved ejection fraction (CpcPH-HFpEF). Totality of evidence supports advancing development of WINREVAIR for this distinct patient population into a registrational Phase 3 study.










Animal Health:


FDA approved NUMELVI for dogs, the first and only second-generation Janus kinase (JAK) inhibitor indicated for the control of pruritus associated with allergic dermatitis in dogs 6 months of age and older.







Business Development:


Announced an agreement to acquire Terns Pharmaceuticals, Inc. (Terns) through a subsidiary.


Expands hematology pipeline with the addition of TERN-701, an investigational oral allosteric BCR::ABL1 tyrosine kinase inhibitor currently in Phase 1/2 development for certain patients with chronic myeloid leukemia (CML).



Transaction expected to close in May.

***Includes a one-time charge of $3.62 per share for the acquisition of Cidara.







The Company has not provided a reconciliation of forward-looking non-GAAP gross margin, non-GAAP operating expenses, non-GAAP other (income) expense, net, non-GAAP effective income tax rate and non-GAAP EPS to the most directly comparable GAAP measures, given it cannot predict with reasonable certainty the amounts necessary for such a reconciliation, including intangible asset impairment charges, legal settlements, and income and losses from investments in equity securities either owned directly or through ownership interests in investment funds, without unreasonable effort. These items are inherently difficult to forecast and could have a significant impact on the Company’s future GAAP results.


The Company now anticipates full-year 2026 sales to be between $65.8 billion and $67.0 billion, including a positive impact from foreign exchange of approximately 1% at mid-April 2026 exchange rates.


The Company continues to expect the full-year non-GAAP effective income tax rate to be between 23.5% and 24.5% including the impact of the non-tax-deductible one-time charge for the acquisition of Cidara.


The Company now expects full-year 2026 non-GAAP EPS to be between $5.04 and $5.16, including a positive impact from foreign exchange of approximately $0.10 per share at mid-April 2026 exchange rates. This range includes a one-time charge of $9.0 billion, or $3.62 per share, related to the acquisition of Cidara. In 2025, non-GAAP EPS of $8.98 was negatively impacted by one-time charges of $0.20 per share in the aggregate related to certain business development transactions.


In April 2026, the Company announced a tender offer to acquire Terns. The Company’s financial outlook does not reflect this transaction, which is expected to be accounted for as an asset acquisition and result in a one-time charge of approximately $5.8 billion, or approximately $2.35 per share. In addition, taking into consideration operational investment to advance TERN-701, as well as the cost of financing the transaction, the Company also anticipates EPS will be negatively impacted by approximately $0.12 over the remainder of 2026 following the close, which is expected in May.


The financial outlook does not assume additional significant potential business development transactions.

3 The Company is providing certain 2026 and 2025 non-GAAP information that excludes certain items because of the nature of these items and the impact they have on the analysis of underlying business performance and trends. Management believes that providing this information enhances investors’ understanding of the Company’s results because management uses non-GAAP results to assess performance. Management uses non-GAAP measures internally for planning and forecasting purposes and to measure the performance of the Company along with other metrics. In addition, annual employee compensation, including senior management’s compensation, is derived in part using a non-GAAP pretax income metric. This information should be considered in addition to, but not as a substitute for or superior to, information prepared in accordance with GAAP. For a description of the non-GAAP adjustments, see Table 2a attached to this release.








4 Reflects expenses related to business combinations, including the amortization of intangible assets, intangible asset impairment charges, and expense or income related to changes in the estimated fair value measurement of liabilities for contingent consideration. Also includes integration, transaction and certain other costs associated with acquisitions and divestitures, as well as amortization of intangible assets related to collaborations, licensing arrangements and asset acquisitions, and recognition of fair value step-up to inventories for asset acquisitions.








5 Includes the estimated income tax impacts on the reconciling items based on applying the statutory rate of the originating territory of the non-GAAP adjustments for all periods presented.
