FDA Approves Pfizer’s IBRANCE Regimen for HR+, HER2+ Metastatic Breast Cancer Frontline MaintenanceJune 24, 2026 2:10 PM
Business Wire First and only CDK4/6 inhibitor approved for HR+ metastatic disease regardless of HER2 status Approval based on data from the collaborative Phase 3 PATINA trial, which showed a 24% risk reduction in disease progression for IBRANCE added to anti-HER2 and endocrine therapies Continues decade-long legacy of IBRANCE helping transform the treatment for HR+ metastatic breast cancer Pfizer Inc. (NYSE: PFE) today announced the U.S. Food and Drug Administration (FDA) approved IBRANCE® (palbociclib) in combination with trastuzumab, with or without pertuzumab, and endocrine therapy for the maintenance treatment of adult patients with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-positive (HER2+) locally advanced or metastatic breast cancer (MBC) following induction treatment. The approval is based on positive results from the Alliance Foundation Trials, LLC (AFT)-sponsored Phase 3 PATINA trial. “Over the past decade, IBRANCE has helped transform metastatic breast cancer treatment, establishing CDK4/6 inhibition as a cornerstone of care,” said Aamir Malik, Chief U.S. Commercial Officer and Executive Vice President, Pfizer. “With today’s FDA approval, IBRANCE becomes the first and only CDK4/6 inhibitor indicated for patients with HR+ metastatic breast cancer regardless of HER2 status, extending its impact to patients who continue to face challenges with treatment resistance. This milestone strengthens confidence in IBRANCE as a CDK4/6 inhibitor backbone across combination regimens, reflecting Pfizer's ongoing leadership in delivering meaningful advances for people with breast cancer.” The PATINA trial demonstrated a 24% reduction in the risk of progression or death following induction treatment with the addition of IBRANCE to anti-HER2 (trastuzumab or trastuzumab plus pertuzumab) and endocrine therapies compared to anti-HER2 and endocrine therapies alone (HR: 0.76 [95% CI, 0.59, 0.97]; one-sided p=0.0134). The safety and tolerability of IBRANCE in PATINA were consistent with its known safety profile. The most commonly reported adverse events with IBRANCE were hematologic toxicities, such as white blood cell decreased and neutrophil count decreased. Non-hematologic adverse events included diarrhea, infections, stomatitis, and fatigue, which were generally mild to moderate in severity. Results from the trial were previously published by AFT in the New England Journal of Medicine and presented at the 2024 San Antonio Breast Cancer Symposium. “Resistance to dual anti-HER2 and endocrine therapy remains a central clinical challenge for patients with HR+, HER2+ metastatic breast cancer – even after an excellent response to initial treatment,” said Otto Metzger, M.D., principal investigator of the trial for Alliance Foundation Trials and Medical Oncologist at the Dana-Farber Cancer Institute. “Based on the results from the PATINA study, the addition of IBRANCE in the maintenance phase can meaningfully extend the time patients go without their disease progressing. This approval gives oncologists a new, evidence-based option to optimize maintenance therapy for their patients with HR+, HER2+ disease.” Approximately 10% of all breast cancers are HR+, HER2+,i which is sometimes referred to as double-positive or triple-positive breast cancer. Historically, there has been limited research specifically focused on the HR+, HER2+ subtype in MBC, and PATINA is the first registrational study to explore the potential of CDK4/6 inhibition in this subtype. Since its initial regulatory approval in 2015, IBRANCE continues to be a standard-of-care first-line treatment for HR+, HER2- MBC and has been prescribed to more than 900,000 patients and approved in more than 100 countries. About the PATINA Trial PATINA (AFT-38) was a randomized, open-label global Phase 3 study to evaluate the efficacy and safety of IBRANCE® (palbociclib) in combination with anti-HER2 therapy (trastuzumab or trastuzumab plus pertuzumab) and endocrine therapy compared to anti-HER2 therapy and endocrine therapy alone as a first-line maintenance therapy (following induction treatment) for patients with HR+, HER2+ MBC. While Pfizer provided funding support for the trial, PATINA was also supported by an academic collaboration led by Alliance Foundation Trials, LLC (AFT) as the global sponsor in partnership with six international cancer research groups in the U.S.(PrECOG), France (French Breast Cancer Intergroup Unicancer), Germany (GBG), Italy (Fondazione Michelangelo), Portugal and Spain (SOLTI), and Australia and New Zealand (Breast Cancer Trials). Study participants who received a median of 6 cycles of induction treatment were randomized to receive IBRANCE, in addition to anti-HER2 therapy and endocrine therapy (n=261), or anti-HER2 therapy and endocrine therapy alone (n=257). The primary endpoint was progression-free survival (PFS) as assessed by the investigator. Overall survival is a secondary endpoint and is not yet mature. About IBRANCE® (palbociclib) IBRANCE is an oral inhibitor of CDKs 4 and 6,ii which are key regulators of the cell cycle that trigger cellular progression.iii,iv In the U.S., IBRANCE is indicated for the treatment of adult patients with HR+, HER2- advanced or metastatic breast cancer in combination with an aromatase inhibitor as initial endocrine-based therapy; or with fulvestrant in patients with disease progression following endocrine therapy. IBRANCE is indicated in combination with inavolisib and fulvestrant for the treatment of adult patients with endocrine-resistant, PIK3CA-mutated, HR-positive, HER2-negative, locally advanced or metastatic breast cancer, as detected by an FDA-approved test, following recurrence on or after completing adjuvant endocrine therapy. IBRANCE is also indicated in combination with trastuzumab, with or without pertuzumab, and endocrine therapy for the maintenance treatment of adult patients with HR-positive, HER2-positive locally advanced or metastatic breast cancer following induction treatment. IMPORTANT SAFETY INFORMATION Neutropenia was the most frequently reported adverse reaction in PALOMA-2 (80%) and PALOMA-3 (83%). In PALOMA-2, Grade 3 (56%) or 4 (10%) decreased neutrophil counts were reported in patients receiving IBRANCE plus letrozole. In PALOMA-3, Grade 3 (55%) or Grade 4 (11%) decreased neutrophil counts were reported in patients receiving IBRANCE plus fulvestrant. In PATINA, neutropenia was the most frequently reported adverse reaction with an incidence of 78%, and Grade ≥3 neutropenia was reported in 61% of patients receiving IBRANCE in combination with trastuzumab, with or without pertuzumab, and endocrine therapy. Based on laboratory findings, 93% had a decrease in neutrophil counts including 47% with Grade 3 and 3.1% with Grade 4. Febrile neutropenia has been reported in 1.8% of patients exposed to IBRANCE across PALOMA-2 and PALOMA-3. One death due to neutropenic sepsis was observed in PALOMA-3. Febrile neutropenia has been reported in 0.8% of patients exposed to IBRANCE in the PATINA study. Inform patients to promptly report any fever. Monitor complete blood count prior to starting IBRANCE, at the beginning of each cycle, on Day 15 of first 2 cycles and as clinically indicated. Dose interruption, dose reduction, or delay in starting treatment cycles is recommended for patients who develop Grade 3 or 4 neutropenia. Severe, life-threatening, or fatal interstitial lung disease (ILD) and/or pneumonitis can occur in patients treated with CDK4/6 inhibitors, including IBRANCE when taken in combination with endocrine therapy. Across clinical trials (PALOMA-1, PALOMA-2, PALOMA-3), 1% of IBRANCE-treated patients had ILD/pneumonitis of any grade, 0.1% had Grade 3 or 4, and no fatal cases were reported. In PATINA, 1% of IBRANCE-treated patients had ILD/pneumonitis of any grade and no Grade 3, 4, or fatal cases were reported. Additional cases of ILD/pneumonitis have been observed in the post-marketing setting, with fatalities reported. Monitor patients for pulmonary symptoms indicative of ILD/pneumonitis (e.g., hypoxia, cough, dyspnea). In patients who have new or worsening respiratory symptoms and are suspected to have developed pneumonitis, interrupt IBRANCE immediately and evaluate the patient. Permanently discontinue IBRANCE in patients with severe ILD or pneumonitis. Based on the mechanism of action, IBRANCE can cause fetal harm. Advise females of reproductive potential to use effective contraception during IBRANCE treatment and for at least 3 weeks after the last dose. IBRANCE may impair fertility in males and has the potential to cause genotoxicity. Advise male patients to consider sperm preservation before taking IBRANCE. Advise male patients with female partners of reproductive potential to use effective contraception during IBRANCE treatment and for 3 months after the last dose. Advise females to inform their healthcare provider of a known or suspected pregnancy. Advise women not to breastfeed during IBRANCE treatment and for 3 weeks after the last dose because of the potential for serious adverse reactions in nursing infants. The most common adverse reactions (≥10%) of any grade reported in PALOMA-2 for IBRANCE plus letrozole vs placebo plus letrozole were neutropenia (80% vs 6%), infections (60% vs 42%), leukopenia (39% vs 2%), fatigue (37% vs 28%), nausea (35% vs 26%), alopecia (33% vs 16%), stomatitis (30% vs 14%), diarrhea (26% vs 19%), anemia (24% vs 9%), rash (18% vs 12%), asthenia (17% vs 12%), thrombocytopenia (16% vs 1%), vomiting (16% vs 17%), decreased appetite (15% vs 9%), dry skin (12% vs 6%), pyrexia (12% vs 9%), and dysgeusia (10% vs 5%).

Serious adverse reactions occurred in 24% of patients in INAVO120 who received IBRANCE plus inavolisib and fulvestrant. Serious adverse reactions occurring in ≥1% of patients receiving IBRANCE plus inavolisib and fulvestrant included anemia (1.9%), diarrhea (1.2%), and urinary tract infection (1.2%). Fatal adverse reactions occurred in 3.7% of patients in INAVO120 who received IBRANCE plus inavolisib and fulvestrant, including (0.6% each) acute coronary syndrome, cerebral hemorrhage, cerebrovascular accident, COVID-19 infection, and gastrointestinal hemorrhage. The most (≥20%) common adverse reactions occurring in INAVO120, including laboratory abnormalities, for IBRANCE plus inavolisib and fulvestrant vs IBRANCE plus placebo and fulvestrant were decreased neutrophils (95% vs 97%), decreased hemoglobin (88% vs 85%), increased fasting glucose (85% vs 43%), decreased platelets (84% vs 71%), decreased lymphocytes (72% vs 68%), stomatitis (51% vs 27%), diarrhea (48% vs 16%), decreased calcium (42% vs 32%), fatigue (38% vs 25%), decreased potassium (38% vs 21%), increased creatinine (38% vs 30%), increased alanine aminotransferase (34% vs 29%), alkaline phosphatase increased (31% vs 23%), nausea (28% vs 17%), decreased sodium (28% vs 19%), decreased magnesium (27% vs 21%), rash (26% vs 19%), decreased appetite (24% vs 9%), COVID-19 infection (23% vs 10%), and headache (22% vs 14%).

Serious adverse reactions in ≥1% of patients receiving IBRANCE in combination with trastuzumab, with or without pertuzumab, and endocrine therapy included infections (8%), headache and pyrexia (1.5% each), and femur fracture (1.2%). Fatal adverse reactions occurred in 1.2% of patients in PATINA who received IBRANCE in combination with trastuzumab, with or without pertuzumab, and endocrine therapy including (0.4% each) death, hepatic hemorrhage, and sepsis. The most common adverse reactions (≥20%) occurring in PATINA, including laboratory abnormalities, for IBRANCE in combination with trastuzumab, with or without pertuzumab, and endocrine therapy vs trastuzumab, with or without pertuzumab, and endocrine therapy were white blood cell decreased (94% vs 25%), neutrophil count decreased (93% vs 19%), creatinine increased (92% vs 87%), hemoglobin decreased (81% vs 47%), diarrhea (70% vs 37%), infections (64% vs 43%), platelet count decreased (59% vs 6%), stomatitis (44% vs 11%), aspartate aminotransferase increased (39% vs 25%), decreased calcium (39% vs 30%), alanine aminotransferase increased (38% vs 28%), decreased potassium (33% vs 17%), fatigue (32% vs 21%), alkaline phosphatase increased (31% vs 23%), nausea (30% vs 15%), asthenia (27% vs 21%), headache (26% vs 18%), rash (22% vs 17%), pruritus (21% vs 17%), and muscle spasms (20% vs 11%). Other Clinical Trials Experience: venous thromboembolism has been reported as an adverse reaction following administration of IBRANCE. Avoid concurrent use of strong CYP3A inhibitors. If patients must be administered a strong CYP3A inhibitor, reduce the IBRANCE dose to 75 mg. If the strong inhibitor is discontinued, increase the IBRANCE dose (after 3-5 half-lives of the inhibitor) to the dose used prior to the initiation of the strong CYP3A inhibitor. Grapefruit or grapefruit juice may increase plasma concentrations of IBRANCE and should be avoided. Avoid concomitant use of strong CYP3A inducers. The dose of sensitive CYP3A substrates with a narrow therapeutic index may need to be reduced as IBRANCE may increase their exposure. For patients with severe hepatic impairment (Child-Pugh class C), the recommended dose of IBRANCE is 75 mg. The pharmacokinetics of IBRANCE have not been studied in patients requiring hemodialysis.

Next-Generation DNA Repair Inhibitors Could Capture Billions in Emerging MarketJune 24, 2026 9:00 AM
InvestorsHub NewsWireNext-Generation DNA Repair Inhibitors Could Capture Billions in Emerging MarketBioMedWire Editorial Coverage: Oncology research is moving through one of its most active stretches in years. DNA Damage Response ("DDR") inhibitors, a category of drugs that work by blocking cancer cells' capacity to fix their own damaged DNA, are growing well beyond the poly ADP ribose polymerase ("PARP") inhibitor that first defined the category. DDR-inhibiting therapies generated an estimated $7 billion-plus in worldwide sales in 2025, and the wider oncology, diagnostics and precision medicine markets are expected to approach about $750 billion by 2030. A fresh wave of inhibitor classes is now taking shape as the next major opportunity. Standing at the leading edge of this shift is Onco-Innovations Limited (CBOE CA: ONCO) (OTCQB: ONNVF) (Profile), a Canadian clinical-stage oncology company developing ONC010(TM), a nanoparticle-encapsulated PNKP inhibitor designed to target a DNA repair enzyme that participates in several distinct repair pathways. As the industry works toward the next generation of synthetic lethality assets, Onco-Innovations occupies a distinctive niche as it builds out its position within the biopharmaceutical and biotechnology space, alongside other established companies such as Merck & Co. Inc. (NYSE: MRK), Pfizer Inc. (NYSE: PFE), GSK plc (NYSE: GSK) and Gilead Sciences Inc. (NASDAQ: GILD), all of which are focused on developing therapies for serious illnesses, including cancer.PARP inhibitors reshaped oncology when they first reached patients some 10 years ago, but they represent just one entry point into a much larger and more intricate biological network.Onco-Technologies owns exclusive worldwide rights to a foundational set of PNKP inhibitor technologies.The company's preclinical program has generated concrete, measurable outcomes that support the biological case for PNKP inhibition in solid tumors.Onco-Innovations holds global rights across three separate layers of protection, with each layer reinforcing the others.Click here to view the custom infographic of the Onco-Innovations editorial.DNA Repair Science Expands Past the PARP EraPARP inhibitors reshaped oncology when they first reached patients some 10 years ago. They put into practice a concept known as synthetic lethality, in which cancers carrying particular DNA repair defects could be selectively destroyed by disabling a secondary repair pathway. The effect was striking in BRCA-mutated cancers, and the drug class has since grown into a market worth billions of dollars. Yet PARP inhibitors represent just one entry point into a much larger and more intricate biological network.The DNA Damage Response system involves dozens of proteins and pathways that cancer cells depend on to withstand chemotherapy, radiation and other forms of cellular stress. Researchers have spent years systematically charting this network in search of new drug targets. A field once confined to academic circles is now attracting serious investment and clinical interest. Artios Pharma, for instance, closed a $115 million Series D financing round late last year to advance mid-stage studies of experimental cancer drugs targeting DNA repair mechanisms beyond PARP, one of the strongest signals yet that this segment has matured into an investable category.The clinical pipeline backs up that narrative. Last month, Artios dosed its first patient in a randomized phase 2 trial of ART6043, a DNA polymerase theta inhibitor, in patients with gBRCA-mutated, HER2-negative breast cancer, advancing a non-PARP DDR target into mid-stage, biomarker-guided development. Also last month, MD Anderson released phase 1 proof-of-concept results for RO7589831, a Werner helicase inhibitor, in cancers exhibiting high microsatellite instability. These are not minor announcements; they demonstrate that novel DDR mechanisms can produce real clinical responses in actual patients.Interest from potential partners in DDR assets has remained resilient even amid broader market turbulence. Last year, Repare Therapeutics out-licensed lunresertib to Debiopharm in a deal worth $10 million upfront, plus up to $257 million tied to milestones. Debiopharm went on to secure U.S. Food and Drug Administration ("FDA") Fast Track designation for a lunresertib combination in April 2026, converting a licensing arrangement into a formal regulatory achievement. The takeaway for investors appears straightforward: Biomarker-defined DDR assets backed by a credible scientific mechanism can still attract partners and earn regulatory recognition, even when funding conditions remain cautious.Polynucleotide Kinase Phosphatase, or PNKP, is a DNA repair enzyme that functions across numerous repair pathways, addressing both single-strand and double-strand break repair. This broader scope gives PNKP inhibitors a potentially wider therapeutic reach than PARP inhibitors, which act primarily on single-strand break repair. Inhibiting PNKP has already shown preclinical activity in colorectal, lung, breast, prostate, ovarian and blood cancers. With worldwide PARP inhibitor revenue forecast to total roughly $12 billion by 2030, PNKP inhibitors are surfacing as a significant drug class positioned to capture share within the expanding DNA Damage Response segment. Onco-Innovations has established itself as the recognized leader for this novel DDR target.Holding First-Mover Ground in Wide-Open CategoryMost competitive space in oncology drug development becomes crowded quickly. PARP inhibitors, PD-1 checkpoint drugs and CDK4/6 inhibitors each drew dozens of rivals once their commercial promise became evident. PNKP inhibitors stand apart from that pattern. The target has been described in academic literature for years, yet the drug-development community has been slow to act on it. That hesitancy created an opening, and Onco-Innovations has moved directly into it.The company owns exclusive worldwide rights to a foundational set of PNKP inhibitor technologies. This encompasses the core inhibitor compounds, the nanoparticle delivery science needed to carry those compounds effectively to tumors, and the synthetic lethality applications that define how the therapy is meant to function. Holding rights across molecular design, delivery mechanism and therapeutic application simultaneously is uncommon at this stage of oncology development.The competitive value of this position becomes clearer with added information. Once a new DDR target draws widespread industry attention, patent landscapes become congested, valuations climb and the window for first movers closes. Onco-Innovations entered the PNKP space while that window was still open. The company's patents cover the PNKP inhibitor technology as well as the ONC010 program, extending protection across the small molecule inhibitors themselves, the delivery system and the clinical applications, which together form a wide and durable competitive barrier.The broader DDR market supplies the commercial backdrop. Per the company, DDR-inhibiting products surpassed $7 billion in global sales last year. The global oncology market overall is forecast to approach $500 billion by 2032, representing growth of 131% across a 10-year span. Within that landscape, PNKP inhibitors occupy a category with no approved competitor and no entrenched incumbent. Rather than fighting for share in an already mature market, the company is effectively building the market itself.Laboratory Evidence Lays Groundwork for Clinical TrialsAmong the central risk factors in early-stage oncology investing is the distance separating laboratory findings from clinical reality. Onco-Innovations has worked methodically to close that gap. The company's preclinical program has generated concrete, measurable outcomes that support the biological case for PNKP inhibition in solid tumors.The standout finding from animal studies relates to survival outcomes in colorectal cancer. Published preclinical data show that the company's novel nanoparticle formulation, ONC010, extended median survival to 60 days in mice with PTEN-deficient colorectal cancer, compared with 23 days in untreated animals, more than double the survival duration. The same body of research showed substantial tumor growth reduction relative to placebo, paired with a favorable toxicity profile.The lack of observed toxicity in animal models carries particular weight. DDR inhibitors have generally run into off-target effects that constrain their clinical usefulness. Onco-Innovations' nanoparticle delivery system was built specifically to deal with this challenge. By pairing the active pharmaceutical ingredient A83B4C63 with a polymer-based micellar carrier, the platform extends circulation time and encourages preferential buildup within tumor tissue while reducing exposure to healthy cells.The company has continued advancing its Chemistry, Manufacturing and Controls program alongside its preclinical research. Onco-Innovations is carrying out manufacturing scale-up and formulation development with Dalton Pharma Services, while running IND-enabling studies, including pharmacokinetic and biodistribution work, with Nucro-Technics. The company recently reported successful API process development and intermediate-scale production for its PNKP inhibitor technology, the kind of key manufacturing announcements that reduce risk on the path toward a first-in-human trial.The company has also set up a subsidiary in Australia to back anticipated phase 1 development through the Therapeutic Goods Administration regulatory pathway. Activation of a first-in-human phase 1 trial is planned later this year. The anticipated clinical approach is underpinned by validated preclinical data, a clear regulatory roadmap and the possibility of pursuing Fast Track designation, considering the substantial unmet need across the target indications.Intellectual Property Designed to Protect ExclusivityIntellectual property forms the foundation of value in early-stage drug development. Without critical IP, clinical achievements fail to result in commercial exclusivity. Onco-Innovations has constructed its IP portfolio with that principle firmly in place. The company owns global rights across three separate layers of protection, with each layer reinforcing the others.The first layer covers the core PNKP inhibitor molecules, the foundational drug candidates from which ONC010 and future programs are derived. The second layer covers the nanoparticle delivery science, specifically the polymer-based micellar carrier system that enables effective tumor-targeted delivery of the inhibitors. This delivery technology is not a peripheral feature; it is central to the program's ability to achieve efficacy without unacceptable toxicity. The third layer protects synthetic lethality applications, which outlines how the therapy is matched to specific tumor biology to maximize selective destruction of cancer cells.Collectively, these patents provide comprehensive protection for the PNKP technology and the ONC010 program. The portfolio is designed to included not just the current lead compound but the main platform itself, supporting the company's specified objective of increasing its PNKP inhibitor technology across additional cancer types.For example, the company has wrapped up a collaborative project with Kuano, applying a quantum-based computational chemistry platform to generate insights aimed at optimizing PNKP inhibitor technology, further reinforcing the molecular foundation underlying the program.Causal AI Speeds Up Precision-Focused Trial DesignDrug development remains costly and slow. The typical oncology drug requires more than a decade and over $1 billion to reach the market, and most candidates that enter clinical trials ultimately fail. Artificial intelligence is being applied with growing frequency to improve those odds, not by substituting for biology but by making it easier to identify the right patients, design more effective trials and interpret results more rapidly.With this in mind, last year Onco-Innovations acquired Inka Health Corp. Inka Health's SynoGraph(TM) platform prototype is a proprietary causal AI engine built specifically for oncology applications. Unlike standard machine learning, which identifies statistical correlations, causal AI is designed to reason about cause-and-effect relationships, a difference that carries significant weight in clinical research, where the gap between association and true causation can be the reason a drug appears effective or ineffective.The SynoGraph offering is designed to support patient stratification, clinical trial design, translational decision-making and evidence generation. The exclusive prototype will combine real-world data, clinical evidence and molecular insights to help predict trial outcomes, treatment efficacy and safety, as well as adverse events. For a company preparing to launch a first-in-human trial, the ability to pinpoint the right patient population before the trial even begins represents a meaningful reduction in clinical risk rather than a mere convenience.Inka Health is also working with both AstraZeneca and GlaxoSmithKline in collaborations centered on predictive modeling, real-world evidence and AI-enabled cancer study. These companies are far from minor partners. And last month, Inka Health started a research partnership within PROmAI, additionally broadening the range of applications for the SynoGraph platform.Folding SynoGraph into the ONC010 development program means Onco-Innovations can use AI-driven patient stratification across its planned clinical studies. This provides the potential to shorten enrollment timelines, enhance the signal within early efficacy data and increase the overall potential for success. Precision-focused trial design is increasingly becoming a significant differentiator within oncology, and Onco-Innovations is working to build that capability internally.Biotech Innovation Continues Advancing Patient CareRecent developments across the biotechnology industry highlight continued progress in the development of innovative therapies and preventive treatments for a wide range of serious diseases. Companies are achieving important regulatory milestones, reporting encouraging clinical trial results and advancing next-generation treatment approaches designed to improve patient outcomes.Merck & Co. Inc. (NYSE: MRK) announced that the FDA has approved an expanded indication for CAPVAXIVE(R) (Pneumococcal 21-valent Conjugate Vaccine). The indication will include children and adolescents aged 2 through 17 years who have completed a primary pediatric pneumococcal vaccination series and have one or more chronic medical conditions that put them at an increased risk for pneumococcal disease. With this approval, CAPVAXIVE is the only PCV specifically indicated and studied in the United States for use in this patient population.Pfizer Inc. (NYSE: PFE) announced that the FDA has approved an expanded indication for HYMPAVZI(R) (marstacimab-hncq). The expanded indication includes the treatment of patients, diagnosed with hemophilia A or B, who are 12 years and older with inhibitors and pediatric patients (ages 6 to 11 years) with or without inhibitors. HYMPAVZI is now indicated in the United States for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adults and pediatric patients 6 years of age and older with hemophilia A (congenital factor VIII deficiency) with or without factor VIII inhibitors, or hemophilia B (congenital factor IX deficiency) with or without factor IX inhibitors.GSK plc (NYSE: GSK) is reporting interim phase 2 data from the global phase 2/3 ROSETTA Lung-02 clinical trial. The trial evaluated the investigational PD-L1xVEGF-A bispecific immunomodulator pumitamig, also known as BNT327 or BMS-986545, plus chemotherapy in patients with previously untreated advanced non-small cell lung cancer ("NSCLC"). The data showed encouraging anti-tumor activity, with high response rates observed in both nonsquamous and squamous NSCLC and at each PD-L1 expression level. The data was presented at the 2026 American Society of Clinical Oncology Annual Meeting.Gilead Sciences Inc. (NASDAQ: GILD) 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(R) (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.As scientific innovation continues to accelerate, the biotechnology sector remains at the forefront of transforming healthcare through novel medicines, advanced biologics and precision treatment strategies. These achievements reflect a growing pipeline of therapies that have the potential to reshape treatment standards and deliver meaningful benefits to patients across diverse disease areas.For further information about Onco-Innovations, visit the Onco-Innovations 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.

Pfizer Announces Topline Phase 3 Results for Sigvotatug Vedotin in Previously Treated Metastatic Non-Squamous Non-Small Cell Lung CancerJune 22, 2026 4:30 PM
Business Wire Pfizer Inc. (NYSE: PFE) today announced topline results from the Phase 3 SigVie-002 study (previously known as Be6A Lung-01) evaluating sigvotatug vedotin, an investigational, potential first-in-class integrin beta-6 (IB6) directed antibody-drug conjugate (ADC). The study enrolled adults with locally advanced, unresectable or metastatic non-squamous non-small cell lung cancer (NSCLC) who had received one or more lines of prior therapy. In the overall population, sigvotatug vedotin did not show a statistically significant improvement in the primary endpoint of overall survival (OS) compared to docetaxel. The safety profile of sigvotatug vedotin was manageable and consistent with prior studies. Encouragingly, in patients who received only one prior line of systemic therapy, which represents two-thirds of the study population, a stronger trend was observed for OS and progression-free survival (PFS) for sigvotatug vedotin over docetaxel. In the exploratory analysis, no clear IB6 expression-response relationship was observed. Detailed results from SigVie-002 will be submitted for presentation at a future medical congress. “Patients with previously treated advanced NSCLC are a historically difficult-to-treat population, and there is clearly more work to be done to improve the outcomes for this population,” said Jeff Legos, Chief Oncology Officer, Pfizer. “Although the overall study results did not demonstrate superiority over docetaxel, it is encouraging that second-line patients treated with sigvotatug vedotin achieved strong efficacy outcomes compared to an established standard of care, alongside a manageable safety profile. This observed clinical benefit, along with our Phase 1 combination data in the first-line setting, reinforces our confidence in the potential of the sigvotatug vedotin program, including an ongoing Phase 3 trial in combination with pembrolizumab in first-line advanced NSCLC.” “It is important not to underestimate the activity of docetaxel as a comparator in this setting. Patients enrolled in this trial were heavily pre-treated, with most having previously received both platinum-based chemotherapy and immunotherapy, yet docetaxel continues to provide meaningful clinical benefit. Although the study did not meet its overall survival endpoint, in second-line patients the data suggest a clinically meaningful survival benefit for sigvotatug vedotin over docetaxel, supporting continued scientific evaluation of sigvotatug vedotin in earlier lines in combination with immunotherapy,” said Solange Peters, M.D., PhD, Chair of Medical Oncology & Thoracic Cancers Clinic, Lausanne University Hospital, Switzerland. “The ability of sigvotatug vedotin to induce immunogenic cell death provides a strong rationale for combination approaches with immunotherapy, particularly in earlier treatment settings where immune competence is better preserved. In this context, the promising phase 1 efficacy signals observed in treatment-naïve patients with high PD-L1 expression warrant further evaluation and may represent a more effective clinical application of this strategy.” In NSCLC, IB6 is expressed on approximately 90% of tumors. IB6 is associated with poor prognosis. Sigvotatug vedotin is a novel ADC designed for high target selectivity of IB6 and rapid internalization, which may help limit binding to other integrins more likely to be expressed in normal tissues and potentially reduce off-target toxicity. Pfizer is evaluating sigvotatug vedotin in several ongoing studies across multiple stages and patient populations in NSCLC and other solid tumors, including: An ongoing Phase 3 study evaluating sigvotatug vedotin + pembrolizumab in 1L NSCLC with PD-L1 tumor proportion score (TPS) ≥50%; and Exploration of sigvotatug vedotin in novel combinations, including with PF’4404, the novel bispecific antibody targeting PD-1 and VEGF, in early-stage lung cancers and other IB6-expressing tumors. Since the acquisition of Seagen, Pfizer has continued to advance a broad ADC portfolio spanning marketed medicines and pipeline programs. Pfizer is progressing multiple differentiated ADC candidates, including fetrastobart vedotin, a PD-L1–directed ADC currently in Phase 3 in NSCLC, additional IB6-targeted ADCs with alternate payloads, and early-stage candidates exploring novel targets and payloads, including topoisomerase I (Topo1) inhibitors and novel auristatin-based payloads. This breadth reinforces the strength of Pfizer’s Oncology pipeline, including the potential for novel combinations with its investigational PD-1xVEGF bispecific antibody (PF-08634404), supporting the company’s goal of delivering 8 potential Oncology breakthroughs by 2030. About the SigVie-002 Trial SigVie-002 (NCT06012435) is an ongoing, open-label randomized, Phase 3, global study evaluating sigvotatug vedotin compared with docetaxel in adult participants with previously treated locally advanced, unresectable or metastatic non-small cell lung cancer (NSCLC). Patients were randomized to receive sigvotatug vedotin administered intravenously on Days 1 and 15 of each 28-day cycle or docetaxel administered intravenously on Day 1 of each 21-day cycle. The primary endpoint of this trial is overall survival (OS). The study enrolled 703 participants. Descriptive, secondary endpoints include progression-free survival (PFS), confirmed objective response rate (ORR) and duration of response (DOR) per RECIST v1.1 as assessed by blinded independent central review (BICR). For more information, visit ClinicalTrials.gov and reference NCT06012435. About Pfizer Oncology At Pfizer Oncology, we are at the forefront of a new era in cancer care.

Robust Phase 2b Efficacy and Favorable Tolerability Support Monthly Dosing for Pfizer’s GLP-1 RA BerobenatideJune 6, 2026 9:00 AM
Business Wire Results from multiple Phase 2b dose finding studies for berobenatide (PF’3944) highlight a potential first-in-class monthly GLP-1 receptor agonist (GLP-1 RA) peptide, and support the planned Phase 3 low, medium and high dosing strategy VESPER-1 achieved a non-placebo-adjusted weight loss of almost 16% with no plateau observed at 32 weeks on 2.4 mg weekly berobenatide Pfizer plans to advance 10 Phase 3 studies for berobenatide in 2026 for chronic weight management and obesity-related comorbidities including knee osteoarthritis and obstructive sleep apnea, as part of a broader program of 20+ obesity trials Pfizer Inc. (NYSE: PFE) today presented detailed results from multiple Phase 2b studies of berobenatide (PF’3944), an investigational, potential first-in-class monthly GLP-1 receptor agonist (GLP-1 RA) peptide, during a late-breaking expert symposium at the 86th Scientific Sessions of the American Diabetes Association (ADA). The objectives for the Phase 2 studies were to identify the right doses for Phase 3 and to test escalation schemes. Across both weekly and monthly dosing in participants with obesity or overweight, with and without type 2 diabetes, the data from the Phase 2b VESPER-1, 2 and 3 studies: provide proof of concept for berobenatide as a potential first-in-class monthly GLP-1 RA peptide that can deliver competitive weight loss; show favorable tolerability for berobenatide, including low gastrointestinal (GI) adverse events and discontinuations despite rapid dose escalation and no allowed step-down; and highlight the potential for monthly delivery in a patient-friendly presentation with a very low 0.5 mL injection volume that provides convenience and scalability advantages. The first clinical experience with the top weekly dose for berobenatide is being presented today for the first time. Results from a 32-week exploratory extension (Part B) of the Phase 2b VESPER-1 study showed a non-placebo-adjusted weight loss of 15.9%* with no plateau observed at 32 weeks on berobenatide (Week 60 of the overall study), in participants who escalated from placebo to 2.4 mg weekly berobenatide. VESPER-1 is evaluating once-weekly berobenatide in adults with obesity or overweight, including Part B to assess the durability of weight loss and the impact of transitioning from once-weekly to less frequent dosing regimens, including once-monthly. "In Phase 2b studies, berobenatide delivered continuous, uninterrupted weight loss at all doses selected for Phase 3, while preserving a tolerable profile as people transitioned from a weekly to a monthly maintenance dose,” said Jim List, MD, PhD, Chief Internal Medicine Officer, Pfizer. “These data highlight the potential for berobenatide to be the first approved monthly GLP-1 RA peptide and support our extensive Phase 3 program that includes 10 studies for chronic weight management and obesity-related comorbidities. With berobenatide as a potential foundational metabolic medicine, both as a single agent and as a combination backbone, Pfizer is advancing a differentiated pipeline with multiple mechanisms and modalities designed to meet the many needs of people living with obesity and related conditions.” Detailed results from the previously reported Phase 2b VESPER-3 study are also being presented today, which is evaluating monthly maintenance dosing of berobenatide in adults with obesity or overweight without type 2 diabetes. In addition, data from the Phase 2b VESPER-2 study, which evaluated weekly dosing of berobenatide in adults with obesity or overweight and type 2 diabetes, showed dose dependent reductions from baseline were observed with berobenatide for both body weight and HbA1c. Of note, there was a 2.2%** reduction in HbA1c achieved with berobenatide 1.6 mg weekly at week 28 (on treatment [efficacy] estimand), compared to a reduction of 0.2% in the placebo group. "Weight management is a lifelong commitment, and the barriers to staying on therapy long-term are just as important as the therapy itself,” said John B. Buse, MD, PhD, Professor of Medicine at the University of North Carolina School of Medicine, Chapel Hill. “The growing body of evidence shows berobenatide delivering meaningful weight loss with a well-tolerated profile following a switch from weekly to monthly dosing in Phase 2b studies. If approved, berobenatide has the potential to not only be effective, but practical and sustainable in real life." The VESPER-6 pivotal Phase 3 study investigating monthly maintenance dosing for berobenatide in adults with obesity or overweight is open for enrollment, as well as the SOLIS-1 Phase 2b study investigating weekly and monthly maintenance dosing of an ultra-long-acting amylin analog (PF'3945) as a monotherapy and in combination with berobenatide. An investor slide presentation with more information about the VESPER clinical development program and the clinical trial results contained in this release will be available on Pfizer’s web site at 10:00 a.m. CT / 11:00 a.m. ET at www.pfizer.com/investors. About Berobenatide and Pfizer’s Cardiometabolic Pipeline Pfizer plans to advance 20+ trials for obesity and related comorbidities in 2026. This includes 10 ongoing and planned Phase 3 trials for berobenatide (PF’3944), an investigational, potential first-in-class monthly GLP-1 receptor agonist (GLP-1 RA) peptide being studied for chronic weight management and obesity-related comorbidities including knee osteoarthritis and obstructive sleep apnea. The growing body of evidence supports advancing an extensive development program for berobenatide as a monotherapy and in combination with various Nutrient-Stimulated Hormone (NuSH) peptides including amylin analogs. About the VESPER Clinical Development Program The VESPER clinical development program is a comprehensive global program evaluating berobenatide across a range of patient populations and dosing regimens in chronic weight management. Phase 2b VESPER studies include: VESPER-1: A Phase 2b trial in adults with obesity or overweight evaluating once-weekly berobenatide, including a 32-week exploratory extension (Part B) assessing the durability of weight loss and the impact of transitioning from once-weekly to less frequent dosing regimens, including once-monthly administration. Part A was the initial 28-week double-blind placebo-controlled portion of the study. VESPER-2: A Phase 2b randomized, double-blind, placebo-controlled trial evaluating once- weekly berobenatide in adults with obesity or overweight and type 2 diabetes, designed to assess weight loss, glycemic control and safety in this population. VESPER-3 is an ongoing 64-week, randomized, double-blind, placebo-controlled study in participants with obesity or overweight without type 2 diabetes. The study is designed to evaluate weekly (QW) titration phase to monthly (QM) dosing of berobenatide in four different titration and QM dose arms, compared to placebo. Phase 3 VESPER studies include: VESPER-4 is an ongoing Phase 3 pivotal study investigating once-weekly berobenatide in adults with obesity or overweight and without type 2 diabetes. VESPER-5 is an ongoing Phase 3 pivotal study investigating once-weekly berobenatide in adults with obesity or overweight and type 2 diabetes. A higher weekly dose of berobenatide (2.4 mg) is currently being evaluated in Phase 3. VESPER-6 is a Phase 3 pivotal study investigating once-monthly berobenatide in adults with obesity or overweight. The study is now open for enrollment. Seven additional planned Phase 3 studies of berobenatide are designed to target comorbidities and increase patient optionality and access. About Obesity Obesity is a growing global epidemic. In 2015, it was estimated that approximately 1.9 billioni people were living with obesity or considered overweight, and this number is expected to grow to more than 2.9 billion by 2030.ii Obesity is a complex metabolic disease, often defined in adults as having a body mass index (BMI) greater than or equal to 30.iii It is associated with more than 200 health conditions,iv contributing to significant chronic disease burden, shortened lifespans, and growing healthcare costs. Despite recent advances in care, for many patients, current therapies are not sufficient—whether due to limited efficacy, tolerability issues that impact adherence, co-morbidities that weight loss alone doesn’t address, or barriers to access and affordability. New waves of innovation that better meet the diverse needs of patients are critical to effectively address this epidemic.

Pfizer’s BRAFTOVI Regimen Nearly Doubles Median Progression-Free Survival in Metastatic Colorectal CancerMay 31, 2026 8:00 AM
Business Wire Cohort 3 analysis from the Phase 3 BREAKWATER study showed a 56% reduction in the risk of disease progression or death compared to traditional chemotherapy regimen Overall survival benefit was also observed, with a 44% reduction in the risk of death BRAFTOVI in combination with cetuximab and fluorouracil-based chemotherapy is the only approved targeted regimen for BRAF V600E-mutant metastatic colorectal cancer Pfizer Inc. (NYSE: PFE) today announced detailed progression-free and overall survival results from Cohort 3, a randomized cohort of the Phase 3 BREAKWATER trial, evaluating BRAFTOVI® (encorafenib) in combination with cetuximab (marketed as ERBITUX®) and FOLFIRI (fluorouracil, leucovorin, and irinotecan) versus FOLFIRI with or without bevacizumab in patients with previously untreated metastatic colorectal cancer (mCRC) with a BRAF V600E mutation. These results will be presented today in a late-breaking oral presentation (Abstract LBA3503) at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting and simultaneously published in the Annals of Oncology. As previously reported, Cohort 3 met its primary endpoint of objective response rate (ORR) by blinded independent central review (BICR). Results for the key secondary endpoint of progression-free survival (PFS) by BICR, being presented at ASCO, show median PFS was nearly doubled with the BRAFTOVI combination regimen (15.2 months) versus the comparator (8.3 months). A clinically meaningful and statistically significant 56% reduction in the risk of disease progression or death was observed for patients treated with the BRAFTOVI combination regimen versus the comparator (Hazard Ratio [HR] of 0.44; 95% Confidence Interval [CI], 0.27–0.70; p=0.0002). Updated overall survival (OS), a descriptive secondary endpoint, showed a 44% reduction in the risk of death for patients treated with the BRAFTOVI combination regimen versus the comparator (HR of 0.56; 95% CI, 0.34–0.94) with a median follow-up of approximately 20 months for both arms. At 18 months, 72% of patients receiving the BRAFTOVI combination regimen were expected to be alive compared to 54.5% of patients receiving the comparator. Median OS was not reached for the BRAFTOVI combination regimen versus a median of 20.3 months for the comparator. “For people with BRAF V600E-mutant metastatic colorectal cancer – a disease that historically has had no targeted treatment options and poor outcomes – these results strengthen confidence in how we can treat this disease,” said Scott Kopetz, M.D., Ph.D., FACP, Professor and Deputy Chair of Gastrointestinal Medical Oncology at The University of Texas MD Anderson Cancer Center and co-principal investigator of the BREAKWATER trial. “A nearly 60% reduction in risk of disease progression or death, combined with prolonged overall survival, reinforces the role of encorafenib in combination with cetuximab and FOLFIRI as a standard of care in the first-line setting for this patient population.” "These compelling results add to a robust body of evidence demonstrating the efficacy of the BRAFTOVI combination treatment across two different established chemotherapy regimens in BRAF V600E-mutant metastatic colorectal cancer,” said Jeff Legos, Chief Oncology Officer, Pfizer. “These findings reaffirm the established role of the BRAFTOVI combination regimen as a cornerstone of first-line treatment for patients and families facing this challenging diagnosis.” In this Cohort 3 analysis, the safety profile of BRAFTOVI in combination with cetuximab and FOLFIRI continued to be consistent with the known safety profile of each respective agent in the regimen, and no new safety signals were identified. The most common adverse events (AEs) (≥25%) in the BRAFTOVI regimen were nausea, diarrhea, vomiting, anemia, alopecia, fatigue, decreased neutrophil count, constipation, decreased appetite, neutropenia, arthralgia, asthenia, and abdominal pain. Grade ≥3 AEs (all causality) occurred in 70.4% of patients receiving BRAFTOVI in combination with cetuximab and FOLFIRI compared to 80.9% of patients receiving FOLFIRI with or without bevacizumab. Treatment discontinuation occurred in 15.5% of patients receiving the BRAFTOVI combination compared to 10.3% for those receiving FOLFIRI. Based on the totality of the Phase 3 and Cohort 3 data in the BREAKWATER study, BRAFTOVI in combination with cetuximab and fluorouracil-based chemotherapy received full approval with an expanded indication from the U.S. Food and Drug Administration (FDA) for patients with BRAF V600E-mutant mCRC in February 2026, offering flexibility in chemotherapy regimen used. Pfizer is continuing its commitment to help non-scientists understand the latest findings with the development of abstract plain language summaries (APLS) for company-sponsored research being presented, which are written in non-technical language. Those interested in learning more can visit www.Pfizer.com/apls to access the summaries. About BREAKWATER
BREAKWATER is a Phase 3, randomized, active-controlled, open-label, multicenter trial of BRAFTOVI with cetuximab, alone or in combination with chemotherapy (mFOLFOX6 or FOLFIRI) in participants with previously untreated BRAF V600E-mutant mCRC. Patients were randomized to receive BRAFTOVI 300 mg orally once daily in combination with cetuximab (discontinued after randomization of 158 patients), BRAFTOVI 300 mg orally once daily in combination with cetuximab and mFOLFOX6 (n=236) or mFOLFOX6, FOLFOXIRI, or CAPOX, with or without bevacizumab (control arm) (n=243). The dual primary endpoints for these study groups are ORR and PFS as assessed by BICR. OS is a key secondary endpoint. In Cohort 3, patients were randomized to receive BRAFTOVI 300 mg orally once daily in combination with cetuximab and FOLFIRI (n=73) or FOLFIRI, with or without bevacizumab (control-arm) (n=74). The primary endpoint of Cohort 3 is ORR as assessed by BICR. PFS as assessed by BICR is a key secondary endpoint; OS is a secondary endpoint. About Colorectal Cancer (CRC)
CRC is the third most common type of cancer in the world, with approximately 1.8 million new diagnoses in 2022.1 It is the second leading cause of cancer-related deaths.2 Overall, the lifetime risk of developing CRC is about 1 in 24 for men and 1 in 26 for women.2 In the U.S. alone, an estimated 158,850 people will be diagnosed with cancer of the colon or rectum in 2026, and approximately 55,000 are estimated to die from the disease each year.3 For 20% of those diagnosed with CRC, the disease has metastasized, or spread, making it harder to treat, and up to 50% of patients with localized disease eventually develop metastases.4 BRAF mutations are estimated to occur in 8-12% of people with mCRC and are associated with a poor prognosis for these patients.5 The BRAF V600E mutation is the most common BRAF mutation, and the risk of mortality in CRC patients with the BRAF V600E mutation is more than double that of patients with no known mutation present.5-7 Despite the high unmet need in BRAF V600E-mutant mCRC, prior to the BRAFTOVI accelerated FDA approval in this indication on December 20, 2024, there were no approved biomarker-driven therapies specifically indicated for people with previously untreated BRAF V600E-mutant mCRC.8,9 About BRAFTOVI® (encorafenib)
BRAFTOVI is an oral small molecule kinase inhibitor that targets BRAF V600E. Inappropriate activation of proteins in the MAPK signaling pathway (RAS-RAF-MEK-ERK) has been shown to occur in certain cancers, including CRC. Pfizer has exclusive rights to BRAFTOVI in the U.S., Canada, Latin America, Middle East, and Africa. Ono Pharmaceutical Co., Ltd. has exclusive rights to commercialize the product in Japan and South Korea, Medison has exclusive rights to commercialize the product in Israel, and Pierre Fabre Laboratories has exclusive rights to commercialize the product in all other countries, including Europe and Asia (excluding Japan and South Korea). INDICATION AND USAGE
BRAFTOVI® (encorafenib) is indicated, in combination with cetuximab and fluorouracil-based chemotherapy, for the treatment of adult patients with metastatic colorectal cancer (mCRC) with a BRAF V600E mutation, as detected by an FDA-authorized test. Limitations of Use: BRAFTOVI is not indicated for treatment of patients with wild-type BRAF CRC. IMPORTANT SAFETY INFORMATION
Refer to the prescribing information for cetuximab and individual product components of mFOLFOX6 and FOLFIRI for recommended dosing and additional safety information. WARNINGS AND PRECAUTIONS New Primary Malignancies: New primary malignancies, cutaneous and noncutaneous, can occur. In the BREAKWATER trial, the following cutaneous malignancies occurred in patients receiving BRAFTOVI in combination with cetuximab and mFOLFOX6: melanocytic nevus in 5.6%, skin papilloma in 3%, basal cell carcinoma in 1.3%, squamous cell carcinoma of skin in 0.9%, keratoacanthoma in 0.4% and malignant melanoma in situ in 0.4%. In patients who received BRAFTOVI in combination with cetuximab and FOLFIRI, skin papilloma occurred in 2.8% and keratoacanthoma in 1.4% of patients. Perform dermatologic evaluations prior to initiating treatment, every 2 months during treatment, and for up to 6 months following discontinuation of treatment. Manage suspicious skin lesions with excision and dermatopathologic evaluation. Dose modification is not recommended for new primary cutaneous malignancies. Based on its mechanism of action, BRAFTOVI may promote malignancies associated with activation of RAS through mutation or other mechanisms. Monitor patients receiving BRAFTOVI for signs and symptoms of noncutaneous malignancies. Discontinue BRAFTOVI for RAS mutation-positive noncutaneous malignancies. Monitor patients for new malignancies prior to initiation of treatment, while on treatment, and after discontinuation of treatment. Tumor Promotion in BRAF Wild-Type Tumors: In vitro experiments have demonstrated paradoxical activation of MAP-kinase signaling and increased cell proliferation in BRAF wild-type cells exposed to BRAF inhibitors. Confirm evidence of BRAF V600E or V600K mutation using an FDA-authorized test prior to initiating BRAFTOVI. Cardiomyopathy: Cardiomyopathy manifesting as left ventricular dysfunction associated with symptomatic or asymptomatic decreases in ejection fraction, has been reported in patients. Assess left ventricular ejection fraction (LVEF) by echocardiogram or multigated acquisition (MUGA) scan prior to initiating treatment, 1 month after initiating treatment, and then every 2 to 3 months during treatment. The safety has not been established in patients with a baseline ejection fraction that is either below 50% or below the institutional lower limit of normal (LLN). Patients with cardiovascular risk factors should be monitored closely. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction. Hepatotoxicity: Hepatotoxicity can occur. In the BREAKWATER trial, the incidence of Grade 3 or 4 increases in liver function laboratory tests in patients receiving BRAFTOVI in combination with cetuximab and mFOLFOX6 was 2.6% for alkaline phosphatase, 1.3% each for ALT and AST. In patients receiving BRAFTOVI in combination with cetuximab and FOLFIRI, the incidence of Grade 3 or 4 increases in liver function laboratory tests was 1.5% each for ALT and AST. Monitor liver laboratory tests before initiation of BRAFTOVI, monthly during treatment, and as clinically indicated. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction. Hemorrhage: Hemorrhage can occur. In the BREAKWATER trial, hemorrhage occurred in 34% of patients receiving BRAFTOVI in combination with cetuximab and mFOLFOX6; Grade 3 or 4 hemorrhage occurred in 3% of patients. In patients receiving BRAFTOVI in combination with cetuximab and FOLFIRI, hemorrhage occurred in 21% of patients. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction. Uveitis: Uveitis, including iritis and iridocyclitis, has been reported in patients treated with BRAFTOVI. In BREAKWATER, the incidence of uveitis among patients who received BRAFTOVI in combination with cetuximab and mFOLFOX6 was 0.4%. Assess for visual symptoms at each visit. Perform an ophthalmological evaluation at regular intervals and for new or worsening visual disturbances, and to follow new or persistent ophthalmologic findings. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction. QT Prolongation: BRAFTOVI is associated with dose-dependent QTc interval prolongation in some patients. In the BREAKWATER trial, an increase of QTcF >500 ms was measured in 4% (9/226) of patients receiving BRAFTOVI in combination with cetuximab and mFOLFOX6. In patients receiving BRAFTOVI in combination with cetuximab and FOLFIRI, an increase of QTcF >500 ms was measured in 1.5% (1/65) of patients. Monitor patients who already have or who are at significant risk of developing QTc prolongation, including patients with known long QT syndromes, clinically significant bradyarrhythmias, severe or uncontrolled heart failure and those taking other medicinal products associated with QT prolongation. Correct hypokalemia and hypomagnesemia prior to and during BRAFTOVI administration. Withhold, reduce dose, or permanently discontinue for QTc >500 ms. Embryo-Fetal Toxicity: BRAFTOVI can cause fetal harm when administered to pregnant women. BRAFTOVI can render hormonal contraceptives ineffective. Advise females of reproductive potential to use effective nonhormonal contraception during treatment with BRAFTOVI and for 2 weeks after the final dose. Risks Associated with Combination Treatment: BRAFTOVI is indicated for use as part of a regimen in combination with cetuximab and mFOLFOX6 or FOLFIRI. Refer to the prescribing information for cetuximab and individual product components of mFOLFOX6 and FOLFIRI for additional risk information. Lactation: Advise women not to breastfeed during treatment with BRAFTOVI and for 2 weeks after the final dose. Infertility: Advise males of reproductive potential that BRAFTOVI may impair fertility. ADVERSE REACTIONS BRAF V600E mutation-positive mCRC, in combination with cetuximab and mFOLFOX6 Serious adverse reactions occurred in 46% of patients who received BRAFTOVI in combination with cetuximab and mFOLFOX6. Serious adverse reactions in >3% of patients included intestinal obstruction (4.7%), pyrexia (3.9%), sepsis (3.4%), and abdominal pain (3.4%) Fatal intestinal obstruction occurred in 0.9%, and fatal large intestinal perforation and gastrointestinal perforation occurred in 0.4% (each) in patients who received BRAFTOVI in combination with cetuximab and mFOLFOX6 Most common adverse reactions (≥25%, all grades) in the BRAFTOVI with cetuximab and mFOLFOX6 arm compared to the control arm (mFOLFOX6 ± bevacizumab or FOLFOXIRI ± bevacizumab or CAPOX ± bevacizumab), and a subset of the control arm (mFOLFOX6 ± bevacizumab), respectively were: peripheral neuropathy (64% vs 53% and 57%), nausea (54% vs 50% and 44%), fatigue (53% vs 41% and 45%), diarrhea (42% vs 50% and 44%), decreased appetite (38% vs 27% and 30%), rash (36% vs 6% and 5%), vomiting (36% vs 22% and 17%), hemorrhage (34% vs 21% and 15%), abdominal pain (32% vs 31% and 30%), arthralgia (32% vs 6% and 7%), pyrexia (29% vs 16% and 17%), and constipation (27% vs 23% and 25%) Most common laboratory abnormalities(≥10%, grade 3 or 4) in the BRAFTOVI with cetuximab and mFOLFOX6 arm compared to the control arm (mFOLFOX6 ± bevacizumab or FOLFOXIRI ± bevacizumab or CAPOX ± bevacizumab), and a subset of the control arm (mFOLFOX6 ± bevacizumab), respectively were: increased lipase (53% vs 28% and 23%), decreased neutrophil count (37% vs 35% and 33%), decreased hemoglobin (19% vs 6% and 7%), decreased white blood cell count (12% vs 8% and 6%), and increased glucose (11% vs 2% and 1%) BRAF V600E mutation-positive mCRC, in combination with cetuximab and FOLFIRI Serious adverse reactions occurred in 39% of patients who received BRAFTOVI in combination with cetuximab and FOLFIRI. Serious adverse reactions in >3% of patients included febrile neutropenia (5.6%) and infusion related reaction (4.2%) Fatal gastrointestinal perforation occurred in 1.4% of patients who received BRAFTOVI in combination with cetuximab and FOLFIRI Most common adverse reactions (>25%, all grades) in the BRAFTOVI with cetuximab and FOLFIRI arm compared to the control arm (FOLFIRI ± bevacizumab) were nausea (61% vs 57%), diarrhea (55% vs 49%), fatigue (47% vs 50%), vomiting (47% vs 31%), alopecia (35% vs 22%), constipation (31% vs 29%), abdominal pain (30% vs 22%), decreased appetite (30% vs 32%), and rash (27% vs 1.5%) Most common laboratory abnormalities (≥10%, grade 3 or 4) in the BRAFTOVI with cetuximab and FOLFIRI arm compared to the control arm (FOLFIRI ± bevacizumab) were: decreased neutrophil count (30% vs 32%), increased lipase (22% vs 12%), decreased white blood cell count (20% vs 6%), and decreased hemoglobin (10% vs 3%) DRUG INTERACTIONS
Strong or moderate CYP3A4 inhibitors: Avoid coadministration of BRAFTOVI with strong or moderate CYP3A4 inhibitors, including grapefruit juice. If coadministration is unavoidable, reduce the BRAFTOVI dose. Strong CYP3A4 inducers: Avoid coadministration of BRAFTOVI with strong CYP3A4 inducers. Sensitive CYP3A4 substrates: Avoid the coadministration of BRAFTOVI with CYP3A4 substrates (including hormonal contraceptives) for which a decrease in plasma concentration may lead to reduced efficacy of the substrate. If the coadministration cannot be avoided, see the CYP3A4 substrate product labeling for recommendations. Dose reductions of drugs that are substrates of OATP1B1, OATP1B3, or BCRP may be required when used concomitantly with BRAFTOVI. Avoid coadministration of BRAFTOVI with drugs known to prolong QT/QTc interval. View the full Prescribing Information. About Pfizer Oncology

TALZENNA Plus XTANDI Improves Radiographic Progression-Free Survival by More Than 50% in Metastatic Prostate CancerMay 30, 2026 8:00 AM
Business Wire First PARP inhibitor + ARPI combination to show consistent rPFS improvement in HRR gene-altered metastatic hormone-sensitive prostate cancer, including both BRCA and non-BRCA alterations There was an estimated 77% probability of remaining progression-free at three years with TALZENNA plus XTANDI Detailed results from pivotal TALAPRO-3 study presented at ASCO 2026 and published in The New England Journal of Medicine Pfizer Inc. (NYSE: PFE) today announced detailed results from the pivotal Phase 3 TALAPRO-3 study of TALZENNA® (talazoparib), an oral poly ADP-ribose polymerase (PARP) inhibitor, in combination with XTANDI® (enzalutamide), an androgen receptor pathway inhibitor (ARPI), in men with homologous recombination repair (HRR) gene-mutated metastatic castration-sensitive prostate cancer (mCSPC), also known as metastatic hormone-sensitive prostate cancer (mHSPC). These results will be presented today in a late-breaking oral presentation (Abstract LBA5007) at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting and simultaneously published in The New England Journal of Medicine. TALZENNA plus XTANDI demonstrated a 52% reduction in the risk of radiographic progression or death compared to placebo plus XTANDI (Hazard Ratio [HR] of 0.48; 95% Confidence Interval [CI], 0.36–0.65; p ? 0.0001). At three years, radiographic progression-free survival (rPFS) rates were estimated at 77% in patients treated with TALZENNA plus XTANDI versus 56% in patients treated with placebo plus XTANDI. With a median follow-up of over 37 months, median rPFS was not reached in the TALZENNA plus XTANDI arm and was 46 months with placebo and XTANDI. The rPFS benefit observed with TALZENNA plus XTANDI was consistent across pre-specified groups with various patient and disease characteristics, including age, Gleason score, geographic region, prostate-specific antigen (PSA) level, and BRCA vs. non-BRCA HRR gene alteration status. At three years, rPFS rates were estimated at 77% vs. 49% in patients with cancer harboring BRCA alterations (HR, 0.37; 95% CI, 0.22–0.61) and 76% vs. 60% in patients with cancer with non-BRCA alterations (HR, 0.57; 95% CI, 0.39–0.82), compared with placebo plus XTANDI. “Delaying progression to castration-resistant disease, the most symptomatic and lethal phase of prostate cancer, remains a significant challenge to patients with mCSPC – especially to those with HRR gene alterations, who often experience poorer outcomes,” said Neeraj Agarwal, M.D., FASCO, Presidential Chair of Cancer Research at Huntsman Cancer Institute at the University of Utah and global lead investigator for TALAPRO-3. “With more than three years of follow-up and median radiographic progression-free survival not reached, TALZENNA plus XTANDI demonstrated durable disease control across a broad HRR-altered population, including patients with BRCA and non-BRCA alterations. These findings underscore the importance of genetic testing as part of routine care and highlight the potential for TALZENNA plus XTANDI to meaningfully improve the outcomes of patients with HRRm mCSPC.” Interim overall survival (OS) results showed a strong trend toward improved OS, a key secondary endpoint, with median OS not reached in either treatment arm (HR, 0.77; 95% CI, 0.56–1.04; p = 0.09). TALZENNA plus XTANDI also improved time to PSA progression (HR, 0.51; 95% CI, 0.37–0.71; p < 0.0001) and time to subsequent anti-cancer therapy (HR, 0.51; 95% CI, 0.38–0.70; p < 0.0001) vs. placebo plus XTANDI. The trial remains ongoing, and OS will be formally assessed at the final analysis. In TALAPRO-3, the safety profile of TALZENNA plus XTANDI was consistent with the known profiles of each agent, and no new safety signals were identified. The most common treatment-emergent adverse events (TEAEs) in the TALZENNA plus XTANDI group were anemia, fatigue, decreased neutrophil count, and asthenia. The most common grade 3 or higher TEAE was anemia, reported by 51% in the TALZENNA plus XTANDI group and 3% in the control group. Five percent of patients discontinued TALZENNA due to anemia. TEAEs were generally manageable with dose modifications and supportive care as needed. “Men with HRR gene-mutated metastatic prostate cancer face significant challenges, with faster disease progression and limited treatment options, making it critical to intervene as early in the course of disease as possible,” said Jeff Legos, Chief Oncology Officer, Pfizer. “The benefit seen with TALZENNA plus XTANDI across a full spectrum of HRR gene alterations reinforces its potential to fundamentally change clinical practice, giving patients significantly more time before disease progression as compared to the current standard of care." Prostate cancer is the second most common cancer in men worldwide, with an estimated 1.5 million new cases diagnosed globally1 and 330,000 new cases anticipated in the United States in 2026.2 mCSPC is a form of advanced prostate cancer that has spread beyond the prostate but is still sensitive to androgen deprivation therapy.3 Approximately 5–10% of newly diagnosed cases are mCSPC,4,5 and up to 30% of these patients harbor HRR gene alterations.6 TALZENNA plus XTANDI in HRR gene-mutated mCSPC is an investigational treatment regimen. The results from TALAPRO-3 are being discussed with global health authorities to potentially expand the combination regimen’s existing indication. TALZENNA plus XTANDI is currently approved in more than 60 countries, including in the U.S. for adults with HRR gene-mutated mCRPC and in the European Union for adults with mCRPC in whom chemotherapy is not clinically indicated. Pfizer is continuing its commitment to help non-scientists understand the latest findings with the development of abstract plain language summaries (APLS) for company-sponsored research being presented at ASCO, which are written in non-technical language. Those interested in learning more can visit www.Pfizer.com/apls to access the summaries. About TALAPRO-3 The Phase 3 TALAPRO-3 trial is a multicenter, randomized, double-blind, placebo-controlled study that enrolled 599 patients with mCSPC (with ≤3 months of ADT [chemical or surgical] with or without an approved ARPI in the mCSPC setting) at sites in the U.S., Canada, Europe, South America, and the Asia-Pacific region. Patients with histologically/cytologically confirmed adenocarcinoma of the prostate without neuroendocrine differentiation, small cell, or signet cell features and with alterations in one or more HRR genes (as per HRR12 gene panel) in the trial were randomized to receive TALZENNA 0.5 mg/day plus XTANDI 160mg/day, or placebo plus XTANDI 160mg/day. The primary endpoint of the trial is investigator-assessed rPFS, defined as the time from the date of randomization to radiographic progression in soft tissue per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1), or in bone per Prostate Cancer Working Group 3 (PCWG3) criteria by investigator assessment, or death, whichever occurs first. Secondary endpoints include OS, objective response rate, duration of response, and patient-reported outcomes. For more information on the TALAPRO-3 trial (NCT04821622), go to www.clinicaltrials.gov. About TALZENNA® (talazoparib) TALZENNA is an oral inhibitor of poly ADP-ribose polymerase (PARP), which plays a role in DNA damage repair. Preclinical studies have demonstrated that TALZENNA blocks PARP enzyme activity and traps PARP at the site of DNA damage, leading to decreased cancer cell growth and cancer cell death. TALZENNA was initially approved in the U.S., EU, and multiple other regions as a single agent for the treatment of adult patients with deleterious or suspected deleterious gBRCAm HER2-negative locally advanced or metastatic breast cancer. TALZENNA in combination with XTANDI was approved by the U.S. Food and Drug Administration (FDA) for the treatment of adult patients with HRR gene-mutated mCRPC in June 2023. The combination was also approved by the European Commission in January 2024 for the treatment of adult patients with mCRPC in whom chemotherapy is not clinically indicated. TALZENNA in combination with XTANDI is approved in more than 60 countries, indications vary by country. TALZENNA® (talazoparib) Indication in the U.S. TALZENNA is a poly (ADP-ribose) polymerase (PARP) inhibitor indicated for: HRR gene-mutated mCRPC: In combination with enzalutamide for the treatment of adult patients with homologous recombination repair (HRR) gene-mutated metastatic castration-resistant prostate cancer (mCRPC). Breast Cancer: As a single agent, for the treatment of adult patients with deleterious or suspected deleterious germline BRCA-mutated (gBRCAm) HER2-negative locally advanced or metastatic breast cancer. Select patients for therapy based on an FDA-approved companion diagnostic for TALZENNA. TALZENNA® (talazoparib) Important Safety Information WARNINGS and PRECAUTIONS Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML), including cases with a fatal outcome, has been reported in patients who received TALZENNA. Overall, MDS/AML has been reported in 0.4% (3 out of 788) of solid tumor patients treated with TALZENNA as a single agent in clinical studies. In TALAPRO-2, MDS/AML occurred in 2 out of 511 (0.4%) patients treated with TALZENNA and enzalutamide and in 0 out of 517 (0%) patients treated with placebo and enzalutamide. The durations of TALZENNA treatment in these 5 patients prior to developing MDS/AML were 0.3, 1, 2, 3, and 5 years. Most of these patients had received previous chemotherapy with platinum agents and/or other DNA damaging agents including radiotherapy. Do not start TALZENNA until patients have adequately recovered from hematological toxicity caused by previous chemotherapy. Monitor blood counts monthly during treatment with TALZENNA. For prolonged hematological toxicities, interrupt TALZENNA and monitor blood counts weekly until recovery. If counts do not recover within 4 weeks, refer the patient to a hematologist for further investigations including bone marrow analysis and blood sample for cytogenetics. If MDS/AML is confirmed, discontinue TALZENNA. Myelosuppression consisting of anemia, neutropenia, and/or thrombocytopenia, have been reported in patients treated with TALZENNA. In TALAPRO-2, Grade ≥3 anemia, neutropenia, and thrombocytopenia were reported, respectively, in 48%, 19%, and 9% of patients receiving TALZENNA and enzalutamide. Forty-two percent of patients (216/511) required a red blood cell transfusion, including 25% (127/511) who required more than one transfusion. Discontinuation due to anemia, neutropenia, and thrombocytopenia occurred, respectively, in 8%, 3%, and 0.4% of patients. Withhold TALZENNA until patients have adequately recovered from hematological toxicity caused by previous therapy. Monitor blood counts monthly during treatment with TALZENNA. If hematological toxicities do not resolve within 28 days, discontinue TALZENNA and refer the patient to a hematologist for further investigations including bone marrow analysis and blood sample for cytogenetics. Embryo-Fetal Toxicity TALZENNA can cause fetal harm when administered to pregnant women. Advise male patients with female partners of reproductive potential or who are pregnant to use effective contraception during treatment and for 4 months following the last dose of TALZENNA. ADVERSE REACTIONS Serious adverse reactions reported in >2% of patients included anemia (9%) and fracture (3%). Fatal adverse reactions occurred in 1.5% of patients, including pneumonia, COVID infection, and sepsis (1 patient each). The most common adverse reactions (≥ 10%, all Grades), including laboratory abnormalities, for patients in the TALAPRO-2 study who received TALZENNA with enzalutamide vs patients receiving placebo with enzalutamide were hemoglobin decreased (79% vs 34%), neutrophils decreased (60% vs 18%), lymphocytes decreased (58% vs 36%), fatigue (49% vs 40%), platelets decreased (45% vs 8%), calcium decreased (25% vs 11%), nausea (21% vs 17%), decreased appetite (20% vs 14%), sodium decreased (22% vs 20%), phosphate decreased (17% vs 13%), fractures (14% vs 10%), magnesium decreased (14% vs 12%), dizziness (13% vs 9%), bilirubin increased (11% vs 7%), potassium decreased (11% vs 7%), and dysgeusia (10% vs 4.5%). Clinically relevant adverse reactions in 2%) in the XTANDI arm compared to placebo in the pooled, randomized, placebo-controlled studies are hemoglobin decrease, neutrophil count decreased, white blood cell decreased, hyperglycemia, hypermagnesemia, hyponatremia, hypophosphatemia, and hypercalcemia. Hypertension: In the combined data from five randomized placebo-controlled clinical trials, hypertension was reported in 14.2% of XTANDI patients and 7.4% of placebo patients. Hypertension led to study discontinuation in < 1% of patients in each arm. Drug Interactions Effect of Other Drugs on XTANDI Avoid coadministration with strong CYP2C8 inhibitors. If coadministration cannot be avoided, reduce the dosage of XTANDI. Avoid coadministration with strong CYP3A4 inducers. If coadministration cannot be avoided, increase the dosage of XTANDI. Effect of XTANDI on Other Drugs Avoid coadministration with certain CYP3A4, CYP2C9, and CYP2C19 substrates for which minimal decrease in concentration may lead to therapeutic failure of the substrate. If coadministration cannot be avoided, increase the dosage of these substrates in accordance with their Prescribing Information. In cases where active metabolites are formed, there may be increased exposure to the active metabolites.

Seven-Year Analysis from Pfizer’s LORBRENA CROWN Trial Shows Longest Progression-Free Survival Reported to Date in Advanced Non-Small Cell Lung CancerMay 29, 2026 8:00 AM
Business Wire Patients had a 55% likelihood of remaining alive without disease progression at seven years, and median progression-free survival was not reached with LORBRENA Updated follow-up analysis solidifies LORBRENA as a preferred standard of care, building upon five-year results Pfizer Inc. (NYSE: PFE) today announced unprecedented seven-year follow-up results from the Phase 3 CROWN trial evaluating LORBRENA® (lorlatinib, a third-generation ALK inhibitor, available in Europe under the brand name LORVIQUA®) versus XALKORI® (crizotinib) in people with previously untreated, anaplastic lymphoma kinase (ALK)-positive advanced or metastatic non-small cell lung cancer (NSCLC). At seven years, patients treated with LORBRENA had a 55% likelihood of remaining alive without disease progression (95% Confidence Interval [CI], 46-63) compared to 3% (95% CI, 1-8) in the XALKORI treatment arm. Further, an updated analysis at seven years of median follow-up showed that investigator-assessed median progression-free survival (PFS) had not been reached with LORBRENA, with an estimated Hazard Ratio (HR) of 0.19 (95% CI, 0.13-0.26), representing an 81% reduction in the risk of disease progression or death compared to XALKORI. Full results from the analysis will be presented today in an oral presentation at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting (Abstract #8502) and simultaneously published in Annals of Oncology. “The updated results from the CROWN trial show unprecedented long-term clinical benefit, with estimates indicating the majority of patients treated with LORBRENA remained alive and progression-free at seven years. While definitive conclusions cannot be drawn across studies, this appears to represent the longest observed progression-free survival reported to date in metastatic or advanced lung cancer,” said Jeff Legos, Chief Oncology Officer, Pfizer. “These findings further showcase Pfizer’s world-class discovery expertise and our commitment to developing breakthroughs that help improve care for people with advanced NSCLC.” Lung cancer is the leading cause of cancer-related deaths worldwide,1 and nearly 230,000 new cases are expected in the U.S. in 2026.2 NSCLC accounts for approximately 75-80% of lung cancers,2,3 with ALK-positive tumors occurring in about 3-5% of NSCLC cases.4 Approximately 25-40% of people with ALK-positive advanced NSCLC may develop brain metastases within two years from initial diagnosis, which are associated with poorer survival and can profoundly affect cognitive function and quality of life.5 LORBRENA was specifically designed and developed by Pfizer to inhibit tumor mutations that drive resistance to other ALK inhibitors and to penetrate the blood-brain barrier. Results from this seven-year follow-up showed that LORBRENA prevented and controlled brain metastases, with a 94% reduction in the risk of developing intracranial (IC) progression (HR, 0.06; 95% CI, 0.03-0.12) and no new IC progression events occurring after the first 30 months. The median time to IC progression was not reached (95% CI, NR-NR) with LORBRENA and was 16.4 months (12.7-21.9) with XALKORI. At the time of analysis, 44% of patients in the CROWN trial were still receiving LORBRENA compared to 3% of patients receiving XALKORI. “These seven-year outcomes from the CROWN study are remarkable not only for their durability of tumor response but for what they represent—a fundamental shift in what clinicians and patients might reasonably expect from treatment for advanced-stage NSCLC,” said Tony Shu-Kam Mok, BBS, Endowed Professor, Li Shu Fan Medical Foundation, Chairman of the Dept. of Clinical Oncology, Chinese University of Hong Kong, and Principal Investigator of the CROWN trial. “Observing this level of long-term benefit with a once-daily oral therapy, both in terms of sustained progression-free survival and prevention of brain metastases, would have been difficult to imagine when we first developed ALK-specific targeted therapy a decade ago and underscores the significance of these results for the lung cancer community.” “Behind every clinical trial is a person continuing to live their life—raising children, pursuing careers, making memories—without their cancer progressing,” said Kenneth Culver, M.D., Director of Research and Clinical Affairs at the non-profit organization ALK Positive. “These seven-year results provide compelling evidence that long-term disease control is possible, and we applaud Pfizer's dedication to advancing treatments that are changing what it means to live with ALK-positive lung cancer.” The safety profiles of LORBRENA and XALKORI were consistent with previous findings, with no new safety signals observed. In this analysis, the most frequent (≥20%) adverse events (AEs) of interest reported in patients treated with LORBRENA included edema, weight gain, peripheral neuropathy, cognitive effects, mood effects, diarrhea, dyspnea, arthralgia, hypertension, headache, cough, pyrexia, hypercholesterolemia, and hypertriglyceridemia. All-cause grade 3/4 AEs occurred in 77% of patients with LORBRENA and in 57% of patients with XALKORI. Treatment-related AEs led to permanent treatment discontinuation in 5% and 6% of patients in the LORBRENA and XALKORI arms, respectively. No new permanent discontinuations due to treatment-related AEs occurred after the first 26 months with LORBRENA. Pfizer is continuing its commitment to help non-scientists understand the latest findings with the development of abstract plain language summaries (APLS) for company-sponsored research being presented at ASCO, which are written in non-technical language. Those interested in learning more can visit www.Pfizer.com/apls to access the summaries. About the CROWN Trial CROWN is a Phase 3, randomized, open-label, parallel two-arm trial in which 296 people with previously untreated ALK-positive advanced NSCLC were randomized 1:1 to receive LORBRENA monotherapy (n=149) or XALKORI monotherapy (n=147). The primary endpoint of the CROWN trial was PFS based on Blinded Independent Central Review (BICR) with a key secondary endpoint of overall survival (OS) for which follow-up is ongoing and results will be reported in the future. Additional secondary endpoints include PFS based on investigator’s assessment, objective response rate (ORR), intracranial objective response rate (IC-ORR), and safety. Given that median PFS was not reached after three years of follow-up, and then later after five years of follow-up, unplanned post-hoc analyses were executed with the intent to further quantify long-term outcomes based on investigator tumor assessment from this trial. The present analysis was performed at a clinically meaningful landmark follow-up of seven years. About LORBRENA® (lorlatinib) LORBRENA is approved in the U.S. for the treatment of adults with metastatic NSCLC whose tumors are ALK-positive as detected by an FDA-approved test. In addition to the U.S., LORBRENA has received approval in more than 80 countries, including Australia, Canada, China, European Union, Japan, and South Korea.

IMPORTANT LORBRENA® (lorlatinib) SAFETY INFORMATION FROM THE U.S. PRESCRIBING INFORMATION Contraindications: LORBRENA is contraindicated in patients taking strong CYP3A inducers, due to the potential for serious hepatotoxicity. Risk of Serious Hepatotoxicity with Concomitant Use of Strong CYP3A Inducers: Severe hepatotoxicity occurred in 10 of 12 healthy subjects receiving a single dose of LORBRENA with multiple daily doses of rifampin, a strong CYP3A inducer. Grade 4 ALT or AST elevations occurred in 50% of subjects, Grade 3 in 33% of subjects, and Grade 2 in 8% of subjects. ALT or AST elevations occurred within 3 days and returned to within normal limits after a median of 15 days (7 to 34 days); median time to recovery in subjects with Grade 3 or 4 or Grade 2 ALT or AST elevations was 18 days and 7 days, respectively. LORBRENA is contraindicated in patients taking strong CYP3A inducers. Discontinue strong CYP3A inducers for 3 plasma half-lives of the strong CYP3A inducer prior to initiating LORBRENA. Central Nervous System (CNS) Effects: A broad spectrum of CNS effects can occur; overall, CNS effects occurred in 52% of the 476 patients receiving LORBRENA. These included seizures (1.9%, sometimes in conjunction with other neurologic findings), psychotic effects (7%; 0.6% severe [Grade 3 or 4]), and changes in cognitive function (28%; 2.9% severe), mood (including suicidal ideation) (21%; 1.7% severe), speech (11%; 0.6% severe), mental status (1.3%; 1.1% severe), and sleep (12%). Median time to first onset of any CNS effect was 1.4 months (1 day to 3.4 years). Overall, 2.1% and 10% of patients required permanent or temporary discontinuation of LORBRENA, respectively, for a CNS effect; 8% required dose reduction. Withhold and resume at same or reduced dose or permanently discontinue based on severity. Hyperlipidemia: Increases in serum cholesterol and triglycerides can occur. Grade 3 or 4 elevations in total cholesterol occurred in 18% and Grade 3 or 4 elevations in triglycerides occurred in 19% of the 476 patients who received LORBRENA. Median time to onset was 15 days for both hypercholesterolemia and hypertriglyceridemia. Approximately 4% and 7% of patients required temporary discontinuation and 1% and 3% of patients required dose reduction of LORBRENA for elevations in cholesterol and in triglycerides in Study B7461001 and Study B7461006, respectively. Eighty-three percent of patients required initiation of lipid-lowering medications, with a median time to onset of start of such medications of 17 days. Initiate or increase the dose of lipid-lowering agents in patients with hyperlipidemia. Monitor serum cholesterol and triglycerides before initiating LORBRENA, 1 and 2 months after initiating LORBRENA, and periodically thereafter. Withhold and resume at same dose for the first occurrence; resume at same or reduced dose of LORBRENA for recurrence based on severity. Atrioventricular (AV) Block: PR interval prolongation and AV block can occur. In 476 patients who received LORBRENA at a dose of 100 mg orally once daily and who had a baseline electrocardiography (ECG), 1.9% experienced AV block and 0.2% experienced Grade 3 AV block and underwent pacemaker placement. Monitor ECG prior to initiating LORBRENA and periodically thereafter. Withhold and resume at reduced or same dose in patients who undergo pacemaker placement. Permanently discontinue for recurrence in patients without a pacemaker. Interstitial Lung Disease (ILD)/Pneumonitis: Severe or life-threatening pulmonary adverse reactions consistent with ILD/pneumonitis can occur. ILD/pneumonitis occurred in 1.9% of patients, including Grade 3 or 4 ILD/pneumonitis in 0.6% of patients. Four patients (0.8%) discontinued LORBRENA for ILD/pneumonitis. Promptly investigate for ILD/pneumonitis in any patient who presents with worsening of respiratory symptoms indicative of ILD/pneumonitis (e.g., dyspnea, cough, and fever). Immediately withhold LORBRENA in patients with suspected ILD/pneumonitis. Permanently discontinue LORBRENA for treatment related ILD/pneumonitis of any severity. Hypertension: Hypertension can occur. Hypertension occurred in 13% of patients, including Grade 3 or 4 in 6% of patients. Median time to onset of hypertension was 6.4 months (1 day to 2.8 years), and 2.3% of patients temporarily discontinued LORBRENA for hypertension. Control blood pressure prior to initiating LORBRENA. Monitor blood pressure after 2 weeks and at least monthly thereafter. Withhold and resume at reduced dose or permanently discontinue based on severity. Hyperglycemia: Hyperglycemia can occur. Hyperglycemia occurred in 9% of patients, including Grade 3 or 4 in 3.2% of patients. Median time to onset of hyperglycemia was 4.8 months (1 day to 2.9 years), and 0.8% of patients temporarily discontinued LORBRENA for hyperglycemia. Assess fasting serum glucose prior to initiating LORBRENA and monitor periodically thereafter. Withhold and resume at reduced dose or permanently discontinue based on severity. Embryo-fetal Toxicity: LORBRENA can cause fetal harm. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use an effective non-hormonal method of contraception, since LORBRENA can render hormonal contraceptives ineffective, during treatment with LORBRENA and for at least 6 months after the final dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with LORBRENA and for 3 months after the final dose. Adverse Reactions: In the pooled safety population of 476 patients who received 100 mg LORBRENA once daily, the most frequent (≥ 20%) adverse reactions were edema (56%), peripheral neuropathy (44%), weight gain (31%), cognitive effects (28%), fatigue (27%), dyspnea (27%), arthralgia (24%), diarrhea (23%), mood effects (21%), and cough (21%). The most frequent (≥ 20%) Grade 3-4 laboratory abnormalities in patients receiving LORBRENA were hypercholesterolemia (21%) and hypertriglyceridemia (21%). In previously untreated patients, serious adverse reactions occurred in 34% of the 149 patients treated with LORBRENA; the most frequently reported serious adverse reactions were pneumonia (4.7%), dyspnea (2.7%), respiratory failure (2.7%), cognitive effects (2.0%), and pyrexia (2.0%). Fatal adverse reactions occurred in 3.4% of patients and included pneumonia (0.7%), respiratory failure (0.7%), cardiac failure acute (0.7%), pulmonary embolism (0.7%), and sudden death (0.7%). In the Phase 1/2 study, serious adverse reactions occurred in 32% of the 295 patients; the most frequently reported serious adverse reactions were pneumonia (3.4%), dyspnea (2.7%), pyrexia (2%), mental status changes (1.4%), and respiratory failure (1.4%). Fatal adverse reactions occurred in 2.7% of patients and included pneumonia (0.7%), myocardial infarction (0.7%), acute pulmonary edema (0.3%), embolism (0.3%), peripheral artery occlusion (0.3%), and respiratory distress (0.3%). Drug Interactions: LORBRENA is contraindicated in patients taking strong CYP3A inducers. Avoid concomitant use with moderate CYP3A inducers, strong CYP3A inhibitors, and fluconazole. If concomitant use of moderate CYP3A inducers cannot be avoided, increase the LORBRENA dose as recommended. If concomitant use with a strong CYP3A inhibitor or fluconazole cannot be avoided, reduce the LORBRENA dose as recommended. Avoid concomitant use of LORBRENA with CYP3A substrates and P-gp substrates, which may reduce the efficacy of these substrates. Lactation: Because of the potential for serious adverse reactions in breastfed infants, instruct women not to breastfeed during treatment with LORBRENA and for 7 days after the final dose. Hepatic Impairment: No dose adjustment is recommended for patients with mild (total bilirubin ≤ ULN with AST > ULN or total bilirubin >1 to 1.5 × ULN with any AST) to moderate (Child-Pugh B) hepatic impairment. In patients with severe hepatic impairment (Child-Pugh C), the recommended dosage of LORBRENA is 50 mg orally once daily. Renal Impairment: In patients with CLcr 15 to 3 times ULN with concurrent total bilirubin elevation >1.5 times ULN (in the absence of cholestasis or hemolysis); otherwise, temporarily suspend and dose-reduce XALKORI as indicated. Interstitial Lung Disease/Pneumonitis: Severe, life-threatening, or fatal interstitial lung disease (ILD)/pneumonitis can occur. Across clinical trials (n=1719), 2.9% of XALKORI-treated patients had any grade ILD, 1.0% had Grade 3/4, and 0.5% had fatal ILD. ILD generally occurred within 3 months after initiation of treatment. Monitor for pulmonary symptoms indicative of ILD/pneumonitis. Exclude other potential causes and permanently discontinue XALKORI in patients with drug-related ILD/pneumonitis. QT Interval Prolongation: QTc prolongation can occur. Across clinical trials (n=1616), 2.1% of patients had QTcF (corrected QT by the Fridericia method) ≥500 ms and 5% of 1582 patients had an increase from baseline QTcF ≥60 ms by automated machine-read evaluation of ECGs. Avoid use in patients with congenital long QT syndrome. Monitor ECGs and electrolytes in patients with congestive heart failure, bradyarrhythmias, electrolyte abnormalities, or who are taking medications that prolong the QT interval. Permanently discontinue XALKORI in patients who develop QTc >500 ms or ≥60 ms change from baseline with Torsade de pointes, polymorphic ventricular tachycardia, or signs/symptoms of serious arrhythmia. Withhold XALKORI in patients who develop QTc >500 ms on at least 2 separate ECGs until recovery to a QTc ≤480 ms, then resume at next lower dosage. Bradycardia: Symptomatic bradycardia can occur. Across clinical trials, bradycardia occurred in 13% of patients treated with XALKORI (n=1719). Avoid use in combination with other medications known to cause bradycardia. Monitor heart rate and blood pressure regularly. If bradycardia occurs, re-evaluate for the use of concomitant medications known to cause bradycardia. Permanently discontinue for life-threatening bradycardia due to XALKORI; however, if associated with concomitant medications known to cause bradycardia or hypotension, hold XALKORI until recovery to asymptomatic bradycardia or to a heart rate of ≥60 bpm. If concomitant medications can be adjusted or discontinued, restart XALKORI at 250 mg once daily with frequent monitoring. Severe Visual Loss: Across clinical trials, the incidence of Grade 4 visual field defect with vision loss was 0.2% of 1719 patients. Discontinue XALKORI in patients with new onset of severe visual loss (best corrected vision less than 20/200 in one or both eyes). Perform an ophthalmological evaluation. There is insufficient information to characterize the risks of resumption of XALKORI in patients with a severe visual loss; a decision to resume should consider the potential benefits to the patient. Vision Disorders: Most commonly visual impairment, photopsia, blurred vision or vitreous floaters, occurred in 63% of 1719 patients. The majority (95%) of these patients had Grade 1 visual adverse reactions. 0.8% of patients had Grade 3 and 0.2% had Grade 4 visual impairment. The majority of patients on the XALKORI arms in Studies 1 and 2 (>50%) reported visual disturbances which occurred at a frequency of 4-7 days each week, lasted up to 1 minute, and had mild or no impact on daily activities. Embryo-Fetal Toxicity: XALKORI can cause fetal harm when administered to a pregnant woman. Advise of the potential risk to the fetus. Advise females of reproductive potential and males with female partners of reproductive potential to use effective contraception during treatment and for at least 45 days (females) or 90 days (males) respectively, following the final dose of XALKORI. ROS1-positive Metastatic NSCLC: Safety was evaluated in 50 patients with ROS1-positive metastatic NSCLC from a single-arm study and was generally consistent with the safety profile of XALKORI evaluated in patients with ALK-positive metastatic NSCLC. Vision disorders occurred in 92% of patients in the ROS1 study; 90% of patients had Grade 1 vision disorders and 2% had Grade 2. Adverse Reactions: Safety was evaluated in a phase 3 study in previously untreated patients with ALK-positive metastatic NSCLC randomized to XALKORI (n=171) or chemotherapy (n=169). Serious adverse events were reported in 34% of patients treated with XALKORI, the most frequent were dyspnea (4.1%) and pulmonary embolism (2.9%). Fatal adverse events in XALKORI-treated patients occurred in 2.3% of patients, consisting of septic shock, acute respiratory failure, and diabetic ketoacidosis. Common adverse reactions (all grades) occurring in ≥25% and more commonly (≥5%) in patients treated with XALKORI vs chemotherapy were vision disorder (71% vs 10%), diarrhea (61% vs 13%), edema (49% vs 12%), vomiting (46% vs 36%), constipation (43% vs 30%), upper respiratory infection (32% vs 12%), dysgeusia (26% vs 5%), and abdominal pain (26% vs 12%). Grade 3/4 reactions occurring at a ≥2% higher incidence with XALKORI vs chemotherapy were QT prolongation (2% vs 0%), esophagitis (2% vs 0%), and constipation (2% vs 0%). In patients treated with XALKORI vs chemotherapy, the following occurred: elevation of ALT (any grade [79% vs 33%] or Grade 3/4 [15% vs 2%]); elevation of AST (any grade [66% vs 28%] or Grade 3/4 [8% vs 1%]); neutropenia (any grade [52% vs 59%] or Grade 3/4 [11% vs 16%]); lymphopenia (any grade [48% vs 53%] or Grade 3/4 [7% vs 13%]); hypophosphatemia (any grade [32% vs 21%] or Grade 3/4 [10% vs 6%]). In patients treated with XALKORI vs chemotherapy, renal cysts occurred (5% vs 1%). Nausea (56%), decreased appetite (30%), fatigue (29%), and neuropathy (21%) also occurred in patients taking XALKORI. Drug Interactions: Use caution with concomitant use of moderate CYP3A inhibitors. Avoid grapefruit or grapefruit juice which may increase plasma concentrations of crizotinib. Avoid concomitant use of strong CYP3A inducers and inhibitors. Avoid concomitant use of CYP3A substrates where minimal concentration changes may lead to serious adverse reactions. If concomitant use of XALKORI is unavoidable, decrease the CYP3A substrate dosage in accordance with approved product labeling. Lactation: Because of the potential for adverse reactions in breastfed children, advise women not to breastfeed during treatment with XALKORI and for 45 days after the final dose. Hepatic Impairment: Crizotinib concentrations increased in patients with pre-existing moderate (any AST and total bilirubin >1.5x ULN and ≤3x ULN) or severe (any AST and total bilirubin >3x ULN) hepatic impairment. Reduce XALKORI dosage in patients with moderate or severe hepatic impairment. The recommended dose of XALKORI in patients with pre-existing moderate hepatic impairment is 200 mg orally twice daily or with pre-existing severe hepatic impairment is 250 mg orally once daily. Renal Impairment: Decreases in estimated glomerular filtration rate occurred in patients treated with XALKORI. Administer XALKORI at a starting dose of 250 mg taken orally once daily in patients with severe renal impairment (CLcr

Pfizer Advances Pivotal Pediatric Pneumococcal Vaccine Program Following Strong Positive Phase 2 ResultsMay 20, 2026 5:05 AM
Business Wire Phase 2 data demonstrate robust immunogenicity, including enhanced response against serotype 3, alongside expanded protection across 25 serotypes; to achieve potential vaccine serotype coverage of 90% in the pediatric population An oral presentation at ISPPD highlighted an approximately 9 to 15-fold higher serotype 3 immunogenicity response after Dose 3 and 4 in infants receiving Pfizer’s 25-valent vaccine candidate (25vPnC) compared to PREVNAR 20® The investigational vaccine candidate was well-tolerated with no safety concerns identified in a Phase 2 study Based on these encouraging results from the Phase 2 program across serotypes and discussions with regulatory authorities, Pfizer initiated its Phase 3 25vPnC pediatric program Company advances adult program to fifth generation 35-valent vaccine candidate Pfizer Inc. (NYSE: PFE) today announced data from its Phase 2 study (NCT06524414) evaluating the safety, tolerability and immunogenicity of a four-dose series of its investigational 25-valent pneumococcal conjugate vaccine candidate PF-07872412 (25vPnC) in infants compared to four doses of PREVNAR 20 at months 2, 4, 6 and 12-15. Based on the strong immune responses observed for all 25vPnC serotypes from Phase 2, compared to PREVNAR 20, Pfizer is confident that the required non-inferiority thresholds may be achieved for the 25vPnG pediatric Phase 3 program. Key preliminary data from the broader Phase 2 study were presented today in an oral presentation at the 14th meeting of the International Society of Pneumonia & Pneumococcal Diseases in Copenhagen, Denmark (ISPPD). Results found: One month after Dose 3, geometric mean titers for serotype 3 were 8.8-fold higher with 25vPnC than with PREVNAR 20 (4.22 vs. 0.48). One month after Dose 4, geometric mean titers for serotype 3 were approximately 15-fold higher with 25vPnC than with Prevnar 20 (13.85 vs. 0.92). This vaccine candidate is expected to cover up to 90% of disease-causing serotypes in children under 5 years of age, which includes approximately 15% from serotype 3. “For more than 25 years, our vaccines have helped protect children from pneumococcal disease, yet significant disease burden remains,” said Annaliesa Anderson, Ph.D., Senior Vice President and Chief Vaccines Officer, Pfizer. “These Phase 2 results reinforce our confidence in a next-generation vaccine designed to expand protection across serotypes while improving responses to key residual disease drivers such as serotype 3. We are advancing our Phase 3 program with the goal of delivering broader and more durable protection for children.” The Phase 2 study is a randomized trial in healthy infants, with initial enrolment beginning in July 2024, evaluating 25vPnC compared with PREVNAR 20. Participants were randomized to receive 25vPnC or PREVNAR 20 at months 2, 4, 6 and 12–15 assessing the safety and tolerability, including local and systemic reactogenicity within seven days after each vaccination, as well as adverse events and serious adverse events in participants who receive at least one dose. The trial also assessed immunogenicity one month after Dose 3 and one month after Dose 4, compared to one month after Dose 3 and Dose 4 with PREVNAR 20. The safety and tolerability profile of 25vPnC was consistent with the currently approved and available pneumococcal vaccine. The most common local reactions were redness, swelling or pain at injection site similar to existing vaccines. Advancing Pediatric and Adult into Pivotal Phase 3 Studies Despite significant reduction in pneumococcal disease burden by the currently available 20-valent standard-of-care-vaccine, serotype 3 remains a notable cause of invasive pneumococcal disease and complicated pneumonia in children. Therefore, based on this Phase 2 data and discussions with regulatory authorities, Pfizer began a pivotal pediatric Phase 3 program in May 2026. The studies evaluate safety, tolerability and immunogenicity of 25vPnC in healthy children where participants receive either 25vPnC or PCV20 at 2, 4, 6 and 12 to 15 months of age. Participants will receive the same vaccine for all four vaccinations for up to 2,400 individuals comparing 25vPnC to the currently licensed 20-valent standard-of-care vaccine. The vaccine candidate covers 25 serotypes including serotype 3, adding five new serotypes to the established vaccine coverage for infants. If successful, this has the potential to broaden protection to about 90% of disease-causing serotypes in US children. Meanwhile, as the strongest opportunity to maintain the company’s current leadership in the adult market over the long term, Pfizer has decided to move directly to a fifth-generation vaccine candidate covering 35 serotypes. This fifth-generation adult candidate has the potential to increase serotype coverage while also improving immunogenicity for critical serotypes including serotype 3 with Pfizer’s proprietary next generation technology. The adult vaccine candidate is expected to enter clinical development by the end of 2026, pending alignment with regulatory authorities. About 25vPnC (25-valent pneumococcal conjugate vaccine candidate) Pfizer's 4th-generation pneumococcal conjugate vaccine candidate builds on the 20 serotypes already covered by PCV20 (PREVNAR 20). It adds five additional serotypes — 15A, 23A, 23B, 24F, and 35B that represents additional 25% coverage of IPD cases compared with PCV20 to broaden coverage to 25 serotypes total, including cross-reactivity. Beyond expanding serotype coverage, 25vPnC also aims to enhance protection against serotype 3, which remains a key driver of residual pneumococcal disease. To achieve this, 25vPnC utilizes next-generation technology specifically designed to elicit a more robust immune response against serotype 3.
