Verastem Oncology Announces U.S. FDA Fast Track Designation for VS-7375, an Oral and Potential Best-in-Class Investigational KRAS G12D (ON/OFF) Inhibitor for the Treatment of KRAS G12D-Mutated Locally Advanced or Metastatic Non-Small Cell Lung CancerJune 3, 2026 4:01 PM
Business Wire Phase 1 TARGET-D 101 dose escalation, dose expansion, and combination clinical trial ongoing with early data updates expected in the first half of 2026 and more mature data expected in the second half of 2026 Phase 2 registration directed, open label TARGET-D 202 clinical trial initiated for 2L/3L advanced non-small cell lung cancer (NSCLC) FDA Fast Track Designation previously granted for VS-7375 for KRAS G12D-mutated advanced or metastatic pancreatic cancer Verastem Oncology (Nasdaq: VSTM), a biopharmaceutical company committed to advancing new medicines for patients with RAS/MAPK pathway-driven cancers, today announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track Designation (FTD) to VS-7375, an oral and potential best-in-class investigational selective KRAS G12D (ON/OFF) inhibitor, for the treatment of adult patients with KRAS G12D-mutated unresectable locally advanced or metastatic non-small cell lung cancer (NSCLC) who have received platinum-based chemotherapy and an anti-PD-(L)1 antibody either concurrently or sequentially. FDA Fast Track Designation was previously granted for VS-7375 for the treatment of KRAS G12D-mutated advanced or metastatic pancreatic cancer. “Non-small cell lung cancer is the most prevalent lung disease with more than 8,000 patients in the U.S. diagnosed each year with KRAS G12D-mutations. Receiving Fast Track designation for VS-7375 reinforces both the significant unmet need and the potential of VS-7375 to improve outcomes for patients with KRAS G12D-mutated lung cancer,” said Michael Kauffman, M.D., Ph.D., president of development at Verastem Oncology. “We are continuing to accelerate the development of VS-7375 across multiple KRAS G12D-driven tumor types, including pancreatic, non-small cell lung, and colorectal cancers to bring a highly targeted, oral treatment option to patients as quickly as possible.” Non-small cell lung cancer (NSCLC) is the most prevalent type of lung cancer, accounting for approximately 80% to 85% of all cases. The majority of patients with NSCLC are diagnosed with advanced-stage disease, either locally advanced (30% to 35%) or metastatic (50% to 55%), which is inoperable. The KRAS G12D mutation occurs in five percent of NSCLC cases and patients with these mutations are known to have reduced responses to standard therapies and poor prognosis. Currently, no therapies are approved by the FDA specifically targeting KRAS G12D mutations in cancer. TARGET-D 202 is a Phase 2, open-label, multi-center study to evaluate VS-7375 900 mg oral dose once daily (QD) in patients with advanced NSCLC who have received one to two prior lines of therapy. Based on positive data in pre-clinical intracranial tumor models, the study is also evaluating VS-7375 in NSCLC patients with asymptomatic untreated brain metastases. In June 2025, Verastem initiated TARGET-D 101, its Phase 1/2 dose escalation, dose expansion and combination clinical trial evaluating VS-7375 in patients with advanced KRAS G12D-mutated solid tumors, including pancreatic, non-small cell lung, and colorectal cancers. Enrollment is ongoing with monotherapy dose escalation progressing from 400 mg through 900 mg once daily (QD) doses without dose-limiting toxicities or major safety concerns observed to date. The study is currently evaluating a 1200 mg QD monotherapy dose and a 900 mg QD cetuximab combination cohort. In the ongoing TARGET-D 101 study, data reported in March 2026 from 23 patients treated across the 400 mg, 600 mg and 900 mg QD dose levels, with a mean treatment duration of 1.6 months (range 0.7–5.6), showed VS-7375 was generally well tolerated, with no drug-related liver function test abnormalities or Grade >2 neutropenia observed as of the January 30, 2026 data cutoff, and lower reported rates of nausea, vomiting and diarrhea compared with data previously reported in China. Following feedback from the FDA, Verastem has further expanded the VS-7375 clinical program with the initiation of three Phase 2 registration-directed trials: TARGET-D 201 in metastatic pancreatic ductal adenocarcinoma, TARGET-D 202 in advanced non-small cell lung cancer, and TARGET-D 203 in metastatic colorectal cancer. About KRAS G12D KRAS G12D represents 26% of all KRAS mutations, making it the most prevalent KRAS mutation in human cancers. The KRAS G12D mutation occurs most commonly in pancreatic (37%), colorectal (12.5%), endometrial (8%), biliary tract (7-15%), and non-small cell lung (5%) cancers. Currently, no therapies are approved by the U.S. Food and Drug Administration (FDA) specifically targeting KRAS G12D mutations in cancer. About VS-7375, an Oral KRAS G12D (ON/OFF) Inhibitor VS-7375 is a potential best-in-class, potent, and selective oral KRAS G12D dual ON/OFF inhibitor. The mechanism of action of VS-7375 is unique in that it binds the active (ON) and inactive (OFF) states of KRAS G12D, with the potential to inhibit KRAS G12D signaling and tumor growth more completely than compounds that block KRAS G12D only in the OFF state or only in the ON state. In June 2025, Verastem initiated TARGET-D 101, a Phase 1/2 dose escalation, dose expansion, and combination clinical trial evaluating the safety and efficacy of VS-7375 in patients with advanced KRAS G12D mutant solid tumors. Verastem has further expanded the VS-7375 clinical program with the initiation of three Phase 2 registration-directed, open-label clinical trials: TARGET-D 201 in second-line advanced or metastatic pancreatic ductal carcinoma, TARGET-D 202 in second/third-line advanced or metastatic non-small cell lung cancer, and TARGET-D 203 in metastatic colorectal cancer. In July 2025, U.S. Food and Drug Administration (FDA) granted Fast Track Designation (FTD) to VS-7375 for the first-line treatment of patients with KRAS G12D-mutated locally advanced or metastatic adenocarcinoma of the pancreas and for the treatment of patients with KRAS G12D-mutated locally advanced or metastatic pancreatic ductal carcinoma who have received at least one prior line of standard systemic therapy. In December 2023, Verastem selected VS-7375 as its lead program from its collaboration with GenFleet Therapeutics, which aims to advance three oncology discovery programs related to RAS/MAPK pathway-driven cancers. The collaboration provides Verastem with an exclusive option to obtain a license for each of the three compounds in the collaboration after the successful completion of pre-determined milestones in a Phase 1 trial. In January 2025, Verastem exercised its license for VS-7375. The licenses would give Verastem development and commercialization rights outside the GenFleet markets of mainland China, Hong Kong, Macau, and Taiwan. GenFleet is developing VS-7375 as GFH375 in China.

Verastem Oncology Launches HCP and Patient Reimagine Campaign to Increase Awareness of AVMAPKI® FAKZYNJA® CO-PACK for KRAS-Mutated Recurrent Low-Grade Serous Ovarian CancerApril 30, 2026 7:30 AM
Business Wire
Low-grade serous ovarian cancer (LGSOC) is a rare ovarian cancer with a high rate of recurrence affecting more than 80% of patients
Integrated healthcare professional (HCP) and patient campaign features new websites and expanded digital resources about the first and only treatment specifically FDA-approved for KRAS-mutated recurrent LGSOC who have received prior systemic therapy
Verastem Oncology (Nasdaq: VSTM), a biopharmaceutical company committed to advancing new medicines for patients with RAS/MAPK pathway-driven cancers, today announced the launch of its Reimagine Recurrent Low-Grade Serous Ovarian Cancer (LGSOC) campaign for AVMAPKI® FAKZYNJA® CO-PACK (avutometinib capsules; defactinib tablets), the first and only treatment specifically approved by the U.S. Food and Drug Administration (FDA) for adult patients with KRAS-mutated recurrent LGSOC who have received prior systemic therapy. The integrated campaign encourages healthcare professionals (HCPs) and patients to rethink what may be possible at and beyond the earliest recurrence for people living with KRAS-mutated recurrent LGSOC.
This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260428101589/en/
LGSOC is a rare and distinct form of ovarian cancer, with unique biology and clinical behavior different from other ovarian cancers. Its tumor growth is primarily driven by the RAS/MAPK pathway with activating mutations, most commonly in the KRAS gene, found in many cancers that often correlate with poor prognosis. Approximately 30% of patients with LGSOC have a KRAS mutation, making it the most common type of gene mutation in the disease. Patients with LGSOC often experience delays in diagnosis and have historically had limited treatment options specifically for their disease.
“The Reimagine Recurrent LGSOC campaign shifts how we think about KRAS-mutated recurrent LGSOC treatment and supporting both patients and healthcare professionals in rethinking what may be possible at and beyond the earliest recurrence,” said Dan Paterson, president and chief executive officer at Verastem Oncology. “The FDA’s accelerated approval of AVMAPKI FAKZYNJA CO-PACK marked an important step forward for patients with KRAS-mutated recurrent LGSOC, underscoring the need for treatments specifically developed for this population. With this campaign, we’re building on that momentum to further inform treatment decisions and support patients throughout their care journey.”
The Reimagine campaign was informed by insights from patients and HCPs, highlighting the need for both emotional resonance and practical, accessible information. For HCPs, the campaign encourages re-evaluation of treatment approaches in the context of a treatment specifically approved by the FDA for KRAS-mutated recurrent LGSOC. For patients, it reflects a desire not only to manage their condition, but to envision a future shaped by progress and meaningful life milestones.
“Patients with KRAS-mutated recurrent LGSOC have historically had limited resources tailored to their specific experience,” said Linda Stamler, vice president of marketing at Verastem Oncology. “The Reimagine Recurrent LGSOC campaign was developed to help identify and support patients who may be appropriate for treatment with AVMAPKI FAKZYNJA CO-PACK. Through this campaign, we are offering resources such as patient stories, tools to help manage side effects, videos explaining mechanism of action and dosing, and guides to help set treatment expectations so patients and HCPs feel more informed and supported.”

About Low-Grade Serous Ovarian Cancer (LGSOC)
LGSOC is a rare ovarian cancer that is insidious and persistent. LGSOC is distinct and different from high-grade serous ovarian cancer (HGSOC) and requires different treatment. LGSOC is highly recurrent and less sensitive to chemotherapy compared to HGSOC. Approximately 6,000-8,000 women in the U.S. and 80,000 worldwide are living with this disease. LGSOC affects younger women with bimodal peaks of diagnosis at ages between 20-30 and 50-60 and has a median survival of approximately ten years. Approximately 70 percent of LGSOC shows RAS pathway-associated mutations, and 30 percent of people with LGSOC have a KRAS mutation. The majority of patients report a negative impact of LGSOC on their mental and physical health, fertility, and long-term quality of life.
About AVMAPKI and FAKZYNJA Combination Therapy
AVMAPKI (avutometinib) inhibits MEK kinase activity while also blocking the compensatory reactivation of MEK by upstream RAF. RAF and MEK proteins are regulators of the RAS/RAF/MEK/ERK (MAPK) pathway. Blocking RAF and/or MEK activates FAK, a key mediator of drug resistance. FAKZYNJA (defactinib) is a FAK inhibitor and together, the avutometinib and defactinib combination was designed to provide a more complete blockade of the signaling that drives the growth and drug resistance of RAS/MAPK pathway-dependent tumors.
The U.S. Food and Drug Administration (FDA) approved AVMAPKI® FAKZYNJA® CO-PACK (avutometinib capsules; defactinib tablets) for the treatment of adult patients with KRAS-mutated recurrent LGSOC who have received prior systemic therapy on May 8, 2025. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial. Verastem is conducting RAMP 301 (GOG-3097/ENGOT-ov81/GTG-UK) (NCT06072781), an international Phase 3 confirmatory trial evaluating the combination of avutometinib and defactinib versus standard chemotherapy or hormonal therapy for the treatment of recurrent low-grade serous ovarian cancer (LGSOC) with and without a KRAS mutation. Verastem is also evaluating avutometinib plus defactinib with standard-of-care chemotherapy as a potential treatment in the first-line for patients with advanced pancreatic cancer (RAMP 205; NCT05669482). Avutometinib and defactinib are not approved by the FDA or any other regulatory authority, either in combination or with other therapies, for any of these investigative uses. Neither avutometinib nor defactinib are approved by the FDA or any other regulatory authority on a stand-alone basis for any use.

Verastem Oncology Announces Two-Year Median Follow-Up Data on AVMAPKI® FAKZYNJA® Combination Therapy (avutometinib capsules; defactinib tablets) in Recurrent Low-Grade Serous Ovarian Cancer at the SGO 2026 Annual Meeting on Women’s CancersApril 10, 2026 7:00 AM
Business Wire
Patients in the Phase 2 RAMP 201 clinical trial demonstrated sustained clinical benefits across multiple efficacy measures highlighting durability of response with a median follow-up of two years
52% of patients with a KRAS mutation and 30% of patients with KRAS wild-type recurrent LGSOC remained on therapy for more than one year
After two years of follow-up, the combination therapy continued to demonstrate a well-tolerated safety profile, with no new safety signals and a low discontinuation rate due to adverse events
Poster presentation of new exposure response analysis demonstrates that the best therapeutic effect of avutometinib plus defactinib can be achieved when using the approved dose and schedule
Verastem Oncology (Nasdaq: VSTM), a biopharmaceutical company committed to advancing new medicines for patients with RAS/MAPK pathway-driven cancers, today announced two-year median follow-up data from the Phase 2 RAMP 201 clinical trial that evaluated AVMAPKI® FAKZYNJA® combination therapy (avutometinib capsules; defactinib tablets) in patients with recurrent low-grade serous ovarian cancer (LGSOC) will be presented today during an oral plenary session at the Society of Gynecologic Oncology (SGO) 2026 Annual Meeting on Women’s Cancers taking place in San Juan, Puerto Rico, April 10-13, 2026.
“Patients who remained on treatment with avutometinib plus defactinib for two years were able to maintain the same level of response and duration of therapy as seen in the primary analysis, suggesting that patients can stay on the combination for a long period of time, derive benefit and have manageable toxicity during long-term administration of these medications,” said Rachel Grisham, M.D., RAMP 201 Presenting Investigator, Section Head, Ovarian Cancer at Memorial Sloan Kettering Cancer Center (MSK) in New York, NY, and Global Lead Principal Investigator of GOG-3097/ENGOT-ov81/GTG-UK/RAMP 301. “As we approach the one-year FDA approval anniversary of avutometinib in combination with defactinib, this analysis reinforces progress in bringing a durable and clinically meaningful option to patients.”
In the updated analysis, with ongoing patients presenting a median follow-up of 24.9 months, efficacy measures, including median duration of response (mDOR) and median progression free survival (mPFS), and safety, are consistent with the primary analysis, which was conducted more than 13 months prior:

*The primary analysis was published in the Journal of Clinical Oncology (Banerjee et al, July 11, 2025).
Fifty percent of patients with KRAS-mutated and 30 percent with KRAS wild-type LGSOC remained on therapy for more than one year. Adverse events (AEs) were consistent with the primary analysis with no new safety signals observed, and a 12 percent discontinuation rate due to adverse events.
“With two years of follow-up demonstrating durable benefit, these analyses reinforce confidence in avutometinib plus defactinib in the real-world setting for patients living with recurrent LGSOC,” said Bradley Monk, M.D., FACOG, FACS, RAMP 201 Investigator and Gynecologic Oncologist with Florida Cancer Specialists & Research Institute and Director GOG-Partners. “Notably, seeing one-third of patients without KRAS mutations remain on therapy for over a year is clinically meaningful, especially in a patient population with limited treatment options. The data also underscore the combination’s manageable safety profile and how dose holds can be used effectively to maintain dose intensity, helping distinguish this treatment strategy from prior MEK-based approaches.”
Exposure-Response Analysis for Avutometinib in Combination with Defactinib in LGSOC
Efficacy analyses included patients with LGSOC (N=158) from the FRAME and RAMP 201 studies, while safety analyses included a broader population (N=303) from the FRAME, RAMP 201, and RAMP 202 studies.
All efficacy endpoints, including overall response rates, duration of response, and best target lesion response, suggest the best therapeutic effect is achieved with the FDA approved dose of avutometinib 3.2 mg twice weekly plus defactinib 200 mg twice daily. While a lower avutometinib dose may mitigate treatment emergent adverse events (TEAEs) (the most frequent being grade ≥2 skin disorders (39.9%; n=121), followed by grade ≥2 gastrointestinal toxicity (34.0%; n=103), grade ≥2 liver function tests (25.1%; n=76), and grade ≥3 creatine phosphokinase elevation (14.5%; n=44)), it may also compromise the efficacy. Importantly, these analyses demonstrated that TEAEs can be monitored and managed with dose interruptions, and subsequently resume treatment at the approved dose level, to allow patients to stay on treatment.
Verastem has an exhibition booth (#608) at the meeting to provide an overview of its approved therapy and ongoing cancer research. The full schedule and poster titles are available online at the SGO 2026 Annual Meeting on Women’s Cancer website.
About RAMP 201
RAMP 201 (ENGOTov60/GOG3052/NCRI) (NCT04625270) was an adaptive, two-part multicenter, parallel cohort, randomized, open-label Phase 2 registration-directed trial evaluating the efficacy and safety of avutometinib alone and in combination with defactinib in patients with recurrent low-grade serous ovarian cancer (LGSOC). The first part of the trial (Part A) determined the selection of the go-forward regimen, which was the combination of avutometinib and defactinib versus avutometinib alone, based on overall response rates. The expansion phases of the trial (Parts B and C) evaluated the safety and efficacy of the go-forward regimen of avutometinib 3.2 mg twice weekly and defactinib 200 mg twice daily. The Part D portion of the trial evaluated a low dose of the combination to inform individualized dose reduction.

FAKZYNJA (defactinib) is a FAK inhibitor and together, the avutometinib and defactinib combination was designed to provide a more complete blockade of the signaling that drives the growth and drug resistance of RAS/MAPK pathway-dependent tumors.
The U.S. Food and Drug Administration (FDA) approved AVMAPKI® FAKZYNJA® CO-PACK (avutometinib capsules; defactinib tablets) for the treatment of adult patients with KRAS-mutated recurrent LGSOC who have received prior systemic therapy on May 8, 2025. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial. Verastem is conducting RAMP 301 (GOG-3097/ENGOT-ov81/GTG-UK) (NCT06072781), an international Phase 3 confirmatory trial evaluating the combination of avutometinib and defactinib versus standard chemotherapy or hormonal therapy for the treatment of recurrent low-grade serous ovarian cancer (LGSOC) with and without a KRAS mutation. Verastem is also evaluating avutometinib plus defactinib with standard-of-care chemotherapy as a potential treatment in the first-line for patients with advanced pancreatic cancer (RAMP 205; NCT05669482). Avutometinib and defactinib are not approved by the FDA or any other regulatory authority, either in combination or with other therapies, for any of these investigative uses. Neither avutometinib nor defactinib are approved by the FDA or any other regulatory authority on a stand-alone basis for any use.

Verastem Oncology Announces Late Breaking and Regular Abstracts Accepted for Presentation at the AACR Annual Meeting 2026March 17, 2026 6:03 PM
Business Wire
Preclinical research with VS-7375 in combination with PRMT5 inhibitors demonstrated strong durable tumor regressions in KRAS G12D pancreatic cancer models
In preclinical pancreatic, lung, and colorectal cancer models, VS-7375 (dual ON/OFF inhibitor) showed deeper and more sustained tumor regression compared to ON-only G12D or pan-RAS inhibitors
Verastem Oncology (Nasdaq: VSTM), a biopharmaceutical company committed to advancing new medicines for patients with RAS/MAPK pathway-driven cancers, today announced multiple abstracts have been accepted for presentation at the American Association for Cancer Research (AACR) Annual Meeting to be held April 17-22, 2026, in San Diego, CA.
“Preclinical data accepted for presentation at the AACR Special Conference in Cancer Research: RAS Oncogenesis and Therapeutics and the AACR Annual Meeting highlight our highly differentiated investigational asset VS-7375, an oral, KRAS G12D (ON/OFF) inhibitor in clinical development for pancreatic, lung, colorectal and other cancers harboring a G12D mutation, the most prevalent KRAS mutation in human cancers,” said Jonathan Pachter, Ph.D., chief scientific officer at Verastem Oncology. “While most agents targeting KRAS G12D-driven cancers bind preferentially only to the “ON” (active) or “OFF” (inactive) state of KRAS, VS-7375 engages both active and inactive states with extremely high affinity and long residence time, which corresponds to superior efficacy across pre-clinical models of G12D mutated cancers.”
Late-Breaking Abstracts
Late-breaking abstracts will be available on the AACR Annual Meeting website on April 17, 2026, 12 p.m. PT.
Session: Late-Breaking Research: Experimental and Molecular Therapeutics 2
Abstract #: LB183 / 5
Title: Strong durable tumor regressions with the KRAS G12D ON/OFF inhibitor VS-7375 in combination with PRMT5 inhibition in MTAP-deleted/KRAS G12D-mutant pancreatic cancer
Date and Time: April 20, 2026, 2 p.m. - 5 p.m. PT
Session: Late-Breaking Research: Experimental and Molecular Therapeutics 2
Abstract #: LB197 / 19
Title: VS-7375, a non-covalent dual ON/OFF KRAS G12D inhibitor, displays superior activity to ON-only KRAS G12D inhibitors in preclinical models of pancreatic cancer
Date and Time: April 20, 2026, 2 p.m. - 5 p.m. PT
Regular Abstracts
The accepted abstracts are available on the AACR Annual Meeting website: AACR Annual Meeting 2026
Session: Novel Antitumor Agents 3
Abstract & Poster Details: Abstract/Poster #7100, Poster Section #13, Poster Board #20
Title: VS-7375: An oral, selective KRAS G12D dual ON/OFF inhibitor with potent anti-tumor activity as a single agent and in combination with other agents
Date and Time: April 22, 2026, 9 a.m. - 12 p.m. PT
In the KP4 KRAS G12D pancreatic cancer model, VS-7375 (50 mg/kg twice daily), zoldonrasib (100 mg/kg once daily) and daraxonrasib (25 mg/kg once daily), produced similar initial tumor regression through day nine. By approximately day 20, however, zoldonrasib and daraxonrasib lost anti-tumor activity with tumor outgrowth, (mean tumor volume >850 mm by day 30) whereas VS-7375 maintained sustained tumor regression (mean tumor volume ~80 mm by day 30), consistent with pharmacodynamic analyses showing durable pathway inhibition only with VS-7375. VS-7375 also showed deeper tumor regression compared to these RAS ON-only inhibitors in KRAS G12D-mutated lung and colorectal xenograft models.
Session: Therapies Targeting Metastasis
Abstract & Poster Details: Abstract/Poster #2232, Poster Section #32, Poster Board #7
Title: Investigating the combined inhibition of RAF, MEK, and FAK in melanoma molecular subtypes
Date and Time: April 20, 2026, 9 a.m. - 12 p.m. PT
In mutant BRAF-driven models, the combination of the FAK inhibitor VS-4718 and the RAF/MEK clamp avutometinib, with or without the mutant BRAF inhibitor encorafenib, significantly delayed tumor onset, induced regression of established tumors and brain metastases, and prolonged overall survival.
AACR Special Conference in Cancer Research: RAS Oncogenesis and Therapeutics
At the AACR Special Conference in Cancer Research: RAS Oncogenesis and Therapeutics held March 5-8, 2026, Dr. Jonathan Pachter, delivered a plenary oral presentation titled, “Anti-tumor efficacy of the selective oral KRAS G12D dual ON/OFF inhibitor VS-7375 as a single agent and in combination with targeted agents.” This presentation can be found on the Company’s website on the Resources page.
About VS-7375, an Oral KRAS G12D (ON/OFF) Inhibitor
VS-7375 is a potential best-in-class, potent, and selective oral KRAS G12D dual ON/OFF inhibitor. VS-7375 is the lead program from the Verastem Oncology discovery and development collaboration with GenFleet Therapeutics. Verastem initiated VS-7375-101, an international Phase 1/2 clinical trial, in June of 2025 in the U.S., that is evaluating the safety and efficacy of VS-7375 in patients with advanced KRAS G12D mutant solid tumors. In July 2025, U.S. Food and Drug Administration (FDA) granted Fast Track Designation (FTD) to VS-7375 for the first-line treatment of patients with KRAS G12D-mutated locally advanced or metastatic adenocarcinoma of the pancreas (PDAC) and for the treatment of patients with KRAS G12D-mutated locally advanced or metastatic PDAC who have received at least one prior line of standard systemic therapy.
About the GenFleet Therapeutics Collaboration
The collaboration with GenFleet Therapeutics aims to advance three oncology discovery programs related to RAS/MAPK pathway-driven cancers. The collaboration provides Verastem with an exclusive option to obtain a license for each of the three compounds in the collaboration after the successful completion of pre-determined milestones in a Phase 1 trial. Verastem selected VS-7375 (also known as GFH375), an oral KRAS G12D (ON/OFF) inhibitor, as its lead program in December 2023 and the license for VS-7375 that was exercised in January 2025 is the first one from this collaboration. The licenses would give Verastem development and commercialization rights outside the GenFleet markets of mainland China, Hong Kong, Macau, and Taiwan.

About RAMP 201
RAMP 201 (ENGOTov60/GOG3052/NCRI) (NCT04625270) was an adaptive, two-part multicenter, parallel cohort, randomized, open-label Phase 2 registration-directed trial evaluating the efficacy and safety of avutometinib alone and in combination with defactinib in patients with recurrent low-grade serous ovarian cancer (LGSOC). The first part of the trial (Part A) determined the selection of the go-forward regimen, which was the combination of avutometinib and defactinib versus avutometinib alone, based on overall response rates. The expansion phases of the trial (Parts B and C) evaluated the safety and efficacy of the go-forward regimen of avutometinib 3.2 mg twice weekly and defactinib 200 mg twice daily. The Part D portion of the trial evaluated a low dose of the combination to inform individualized dose reduction.
About Low-Grade Serous Ovarian Cancer (LGSOC)
LGSOC is a rare ovarian cancer that is insidious and persistent. LGSOC is distinct and different from high-grade serous ovarian cancer (HGSOC) and requires different treatment. LGSOC is highly recurrent and less sensitive to chemotherapy compared to HGSOC. Approximately 6,000-8,000 women in the U.S. and 80,000 worldwide are living with this disease. LGSOC affects younger women with bimodal peaks of diagnosis at ages between 20-30 and 50-60 and has a median survival of approximately ten years. Approximately 70 percent of LGSOC shows RAS pathway-associated mutations, and 30 percent of people with LGSOC have a KRAS mutation. The majority of patients report a negative impact of LGSOC on their mental and physical health, fertility, and long-term quality of life.
About AVMAPKI and FAKZYNJA Combination Therapy
AVMAPKI (avutometinib) inhibits MEK kinase activity while also blocking the compensatory reactivation of MEK by upstream RAF. RAF and MEK proteins are regulators of the RAS/RAF/MEK/ERK (MAPK) pathway. Blocking RAF and/or MEK activates FAK, a key mediator of drug resistance.

Verastem Oncology Reports Fourth Quarter and Full Year 2025 Financial Results and Highlights Recent Business UpdatesMarch 4, 2026 4:01 PM
Business Wire
AVMAPKI™ FAKZYNJA™ CO-PACK net product revenues of $17.5 million for the fourth quarter of 2025 and $30.9 million for the full year 2025, following accelerated U.S. FDA approval in May 2025
Based on FDA guidance, Company to develop Phase 2 registration-directed protocols to evaluate VS-7375, a highly selective, oral KRAS G12D (ON/OFF) inhibitor with best-in-class potential, in 2L PDAC, 2L/3L NSCLC and 2L+ CRC in combination with cetuximab
Cleared multiple dose levels of VS-7375 with no DLTs, continuing dose escalation to 1200 mg QD; cleared 600 mg QD dose level of VS-7375 in combination with cetuximab with no DLTs; continuing higher dose evaluations
Company cash, cash equivalents, and investments of $205 million as of December 31, 2025; pro-forma year-end cash, cash equivalents and investments of $234 million inclusive of net proceeds from exercise of expiring cash warrants; expected cash runway into first half of 2027
Verastem Oncology (Nasdaq: VSTM), a biopharmaceutical company committed to advancing new medicines for patients with RAS/MAPK pathway-driven cancers, today reported financial results for the three months and full year ended December 31, 2025, and highlighted recent progress.
“2025 was a transformative year for us, highlighted by the landmark FDA approval of AVMAPKI FAKZYNJA CO-PACK, the only medicine approved to specifically treat KRAS-mutated recurrent LGSOC. The launch is off to a strong start, and this novel-novel combination therapy is gaining positive response across the LGSOC community with gynecologic and medical oncologists in both academic and community settings increasingly turning to it when patients experience a first or subsequent recurrence. We also made considerable progress with VS-7375, our oral, KRAS G12D (ON/OFF) inhibitor with best-in-class potential for solid tumor cancers, clearing multiple dose levels across both monotherapy and cetuximab combination cohorts with no DLTs or major toxicities. Building on the insights from the China data, the tolerability profile that is emerging with VS-7375 in the U.S. has shown meaningful improvement and supports continued dose escalation,” said Dan Paterson, president and chief executive officer at Verastem Oncology. “In 2026, our priorities are to continue driving a strong launch of AVMAPKI FAKZYNJA CO-PACK to fuel sustainable growth, while we continue to accelerate the clinical development of VS-7375 and breakout Phase 2 registration-directed clinical trials in pancreatic, lung, and colorectal cancers.”
Fourth Quarter 2025 and Recent Highlights
AVMAPKI™ FAKZYNJA™ CO-PACK (avutometinib capsules; defactinib tablets) U.S. Launch
AVMAPKI FAKZYNJA CO-PACK generated net product revenues of $17.5 million for the fourth quarter of 2025 and $30.9 million for the full year 2025, following accelerated U.S. Food and Drug Administration (FDA) approval in May 2025, approximately two months ahead of its Prescription Drug User Fee Act (PDUFA) action date of June 30, 2025.
On February 4, 2026, the Company announced updated data for RAMP 201J in Japan with a data cutoff of January 30, 2026. Of the 16 patients enrolled with a median follow-up of 10 months, a confirmed overall response rate (ORR) of 38% (6/16) was achieved by investigator assessment. Among patients with KRAS-mutated recurrent low-grade serous ovarian cancer (LGSOC), the confirmed ORR was 57% (4/7) and the disease control rate (DCR) was 100% (7/7). Among patients with KRAS wild-type recurrent LGSOC, the confirmed ORR was 22% (2/9) and the DCR was 89% (8/9). Of the 16 patients enrolled, 11 patients remain on treatment. No patients discontinued due to an adverse event. The safety profile was similar to previously reported data outside of Japan. Steady-state exposures of avutometinib and defactinib in the RAMP 201J study were comparable to those seen in RAMP 201.
On February 25, 2026, the annual update of the National Comprehensive Cancer Network® (NCCN®) Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for Ovarian Cancer was released. The Guidelines did not expand the recommendation for avutometinib plus defactinib to include patients with recurrent LGSOC without a KRAS mutation. The Guidelines retained the category 2A recommendation for avutometinib plus defactinib for patients with KRAS-mutated recurrent LGSOC.
“We are disappointed for the patients with KRAS wild-type recurrent LGSOC, who currently have no targeted, FDA-approved treatment options specifically for their disease and face a particularly poor prognosis. Across three separate clinical trials (the FRAME study, RAMP 201, and RAMP 201J) we have observed what we believe are robust objective responses rates for patients with recurrent LGSOC with and without KRAS mutations. We remain committed to advancing the clinical evidence through longer term follow-up analyses from the RAMP 201 study planned for the SGO annual meeting, and completing our ongoing confirmatory RAMP 301 Phase 3 clinical trial, which includes patients with and without KRAS mutations, and look forward to sharing these data with the NCCN and the medical community to support future guideline consideration,” said John Hayslip, chief medical officer at Verastem Oncology.
Expected Key Milestones:
Maximize adoption of AVMAPKI FAKZYNJA CO-PACK in the U.S. as the treatment of choice at the earliest recurrence, leveraging its robust clinical data.
Report a topline readout of the primary endpoint in the RAMP 301 trial in mid-2027.
Continue to pursue regulatory paths for potential expansion into Europe and Japan.
VS-7375, an Oral KRAS G12D (ON/OFF) Inhibitor in Advanced Solid Tumors
The Company today announced an update on its progress with the VS-7375-101 Phase 1/2 study:
After clearing the 900 mg daily (QD) dose level with no dose-limiting toxicities (DLTs), the dose escalation phase will continue to 1200 mg QD to further interrogate the dose range and characterize the safety, tolerability, and efficacy profile of VS-7375.
The 600 mg QD dose level of VS-7375 in combination with cetuximab was cleared with no DLTs and higher doses are now being evaluated.
In a pharmacokinetics (PK) analysis, doses of VS-7375 at 600 mg QD and above, with feeding and anti-emetic prophylaxis, yielded similar exposures to fasted patients in China. The exposures achieved cover the exposures in preclinical models necessary for maximal anti-tumor efficacy.
As of the January 30, 2026 data cutoff, VS-7375 demonstrated an encouraging safety profile and was generally well-tolerated across all monotherapy dose levels evaluated to date. Patients (n=23) receiving VS-7375 at either 400 mg QD, 600 mg QD or 900 mg QD with a mean duration of therapy of 1.6 months (0.7-5.6), reported no drug related liver function test abnormalities. There was no drug-related neutropenia greater than Grade 2 and rates of nausea, vomiting and diarrhea remained lower than those reported by the Company’s partner in China. No DLTs have been reported to date, and the maximum tolerated dose has not been reached.
Following recent feedback from the FDA, the Company is amending the VS-7375-101 Phase 1/2 protocol to separate out disease-specific Phase 2 registration-directed trials for KRAS G12D mutated 2L pancreatic ductal adenocarcinoma (PDAC) and 2L/3L non-small cell lung cancer (NSCLC) (monotherapy) and 2L+ colorectal cancer (CRC) in combination with cetuximab.
In January 2026, the Company reported updates on its VS-7375-101 trial including that it had cleared the 400 mg QD, 600 mg QD and 900 mg QD dose levels with no DLTs and no major toxicities. The VS-7375 monotherapy expansion cohorts were initiated, and the cohort sizes were expanded in 2L PDAC, 2L/3L NSCLC, and 2L+ other KRAS G12D-mutated solid tumors. In the VS-7375 dose-escalation combination cohort, the 400 mg QD dose was cleared in combination with cetuximab with no DLTs. The combination dose escalation cohorts were initiated in 1L NSCLC and 2L PDAC at the end of 2025.
In October 2025, the Company announced a preliminary update on the Phase 1/2 monotherapy dose escalation trial of VS-7375 in patients with previously treated advanced KRAS G12D mutant solid tumors. In the study, VS-7375 cleared both the 400 mg QD and the 600 mg QD monotherapy doses with no DLTs observed. At the two dose levels evaluated in the U.S. cohort, no nausea, vomiting, or diarrhea greater than Grade 1 were reported. In addition, no new safety signals have been observed relative to earlier data presentations in both PDAC and NSCLC by GenFleet Therapeutics, the Company’s partner in China. Of the five efficacy evaluable patients in the VS-7375-101 study with at least one scan, four out of five patients have had a tumor reduction and were still on treatment.
The Company shared multiple updates from GenFleet and its ongoing evaluation of VS-7375, known as GFH375, in China:
On March 2, 2026, GenFleet announced that GFH375 was granted its first Breakthrough Therapy Designation in China for patients with KRAS G12D-mutated NSCLC who have received prior systemic therapy.
In December 2025, GenFleet announced the initiation of a registrational Phase 3 study for GFH375 in patients with pretreated KRAS G12D-mutated metastatic pancreatic cancer in China.
In October 2025, the Company announced updated data for GFH375 in PDAC featured in a late-breaking oral presentation at the European Society for Medical Oncology (ESMO) Congress. GenFleet shared additional analyses of this data set on October 27, 2025:
In a subgroup analysis, 12 patients with 2L PDAC at 600 mg QD achieved an ORR of 58.3% and a DCR of 100%. In the 3L+ setting, 47 PDAC patients receiving 600 mg QD achieved an ORR of 36.2% and a DCR of 95.7%. In the 2L subgroup, the median progression free survival (mPFS) and median overall survival (mOS) have not been reached. An additional analysis of gastrointestinal disorders, hematological toxicities, and liver enzyme abnormalities in 2L+ patients with PDAC (n=66) at 600 mg QD showed no adverse events Grade ≥3 occurred at rates above 8.0%.
In an analysis of pre-treated patients with NSCLC at 600 mg QD, the four-month PFS rate was greater than 75% and the mPFS has not been reached. The median follow-up time was 4.2 months.
In October 2025, GenFleet announced that the first patient has been dosed in a Phase 1b/2 study of GFH375 combined with cetuximab or chemotherapy for advanced solid tumors, including 1L PDAC, in China.
In August 2025, the Company announced data of GFH375 would be featured in a mini oral presentation at the IASLC 2025 World Conference on Lung Cancer (WCLC) on September 8, 2025. At the recommended Phase 2 dose (RP2D) of 600 mg QD, the ORR was 68.8% (11/16) (both confirmed and unconfirmed) and the DCR was 93.8% (15/16). Among the 26 evaluable patients with NSCLC treated across all dose levels, the ORR was 57.7% (15/26) (both confirmed and unconfirmed) and the DCR was 88.5% (23/26).
Expected Key Milestones:
Report early data from the VS-7375-101 trial in 1H 2026.
Select the RP2D with cetuximab and initiate the CRC combination expansion cohort in 1H 2026.
Complete enrollment in combination dose-escalation cohorts in mid-2026.
Complete enrollment in monotherapy expansion cohorts in 2H 2026.
Select the RP2D and plan to initiate the PDAC and NSCLC combination expansion cohorts in 2H 2026.
RAMP 205: Avutometinib Plus Defactinib in Combination with Chemotherapy in 1L Metastatic Pancreatic Cancer
In November 2025, the Company announced that enrollment was completed in the expansion cohort in Q3 2025.
Expected Key Milestone:
Report an update on the safety and efficacy of the RAMP 205 expansion cohort with at least six months of follow-up on all patients in Q2 2026.

Use of Non-GAAP Financial Measures
To supplement Verastem Oncology’s condensed consolidated financial statements, which are prepared and presented in accordance with generally accepted accounting principles in the United States (GAAP), the Company uses the following non-GAAP financial measures in this press release: non-GAAP adjusted net loss and non-GAAP net loss per share. These non-GAAP financial measures exclude certain amounts or expenses from the corresponding financial measures determined in accordance with GAAP.
Management believes this non-GAAP information is useful for investors, taken in conjunction with the Company’s GAAP financial statements, because it provides greater transparency and period-over- period comparability with respect to the Company’s operating performance and can enhance investors’ ability to identify operating trends in the Company’s business. Management uses these measures, among other factors, to assess and analyze operational results and trends and to make financial and operational decisions. Non-GAAP information is not prepared under a comprehensive set of accounting rules and should only be used to supplement an understanding of the Company’s operating results as reported under GAAP, not in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP. In addition, these non-GAAP financial measures are unlikely to be comparable with non-GAAP information provided by other companies. The determination of the amounts that are excluded from non-GAAP financial measures is a matter of management judgment and depends upon, among other factors, the nature of the underlying expense or income amounts. Reconciliations between these non-GAAP financial measures and the most comparable GAAP financial measures for the three months and year ended December 31, 2025, and 2024 are included in the tables accompanying this press release after the unaudited condensed consolidated financial statements.
About AVMAPKI and FAKZYNJA Combination Therapy
AVMAPKI (avutometinib) inhibits MEK kinase activity while also blocking the compensatory reactivation of MEK by upstream RAF. RAF and MEK proteins are regulators of the RAS/RAF/MEK/ERK (MAPK) pathway. Blocking RAF and/or MEK activates FAK, a key mediator of drug resistance. FAKZYNJA (defactinib) is a FAK inhibitor and together, the avutometinib and defactinib combination was designed to provide a more complete blockade of the signaling that drives the growth and drug resistance of RAS/MAPK pathway-dependent tumors.
The U.S. Food and Drug Administration (FDA) approved AVMAPKI™ FAKZYNJA™ CO-PACK (avutometinib capsules; defactinib tablets) for the treatment of adult patients with KRAS-mutated recurrent LGSOC who have received prior systemic therapy on May 8, 2025. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial. Verastem is conducting RAMP 301 (GOG-3097/ENGOT-ov81/GTG-UK) (NCT06072781), an international Phase 3 confirmatory trial evaluating the combination of avutometinib and defactinib versus standard chemotherapy or hormonal therapy for the treatment of recurrent low-grade serous ovarian cancer (LGSOC) with and without a KRAS mutation. Verastem is also evaluating avutometinib plus defactinib with standard-of-care chemotherapy as a potential treatment in the first-line for patients with advanced pancreatic cancer (RAMP 205; NCT05669482). Avutometinib and defactinib are not approved by the FDA or any other regulatory authority, either in combination or with other therapies, for any of these investigative uses. Neither avutometinib nor defactinib are approved by the FDA or any other regulatory authority on a stand-alone basis for any use.

Verastem Oncology Provides Preliminary Fourth Quarter and 2025 Revenue and Business Updates and Outlines 2026 Strategic Priorities for Novel Portfolio Targeting RAS/MAPK Pathway-Driven CancersFebruary 4, 2026 7:30 AM
Business Wire
Based on preliminary, unaudited results, Verastem expects AVMAPKI™ FAKZYNJA™ CO-PACK net product revenues of approximately $17.5 million for the fourth quarter of 2025 and approximately $30.9 million for the full year 2025, following U.S. FDA approval in May 20251
Company plans to continue rapidly advancing clinical development program for VS-7375, a highly selective, oral KRAS G12D (ON/OFF) inhibitor with best-in-class potential, in several advanced KRAS G12D solid tumor indications
Company sees preliminary unaudited cash, cash equivalents, and investments of $205 million as of December 31, 2025; pro-forma year-end cash, cash equivalents and investments of $234 million inclusive of net proceeds from exercise of expiring cash warrants; expected cash runway into first half of 2027
Leadership to participate in a fireside chat at the Guggenheim Emerging Outlook Conference in New York City on February 11, 2026
Verastem Oncology (Nasdaq: VSTM), a biopharmaceutical company committed to advancing new medicines for patients with RAS/MAPK pathway-driven cancers, today announced preliminary, unaudited fourth quarter and full year 2025 net product revenues for AVMAPKI™ FAKZYNJA™ CO-PACK, business updates, and 2026 priorities.
"2025 was a transformative year for Verastem Oncology and the patients we serve. We transitioned to a commercial-stage company with the launch of AVMAPKI FAKZYNJA CO-PACK, the first treatment specifically approved by the FDA for KRAS-mutated recurrent low-grade serous ovarian cancer (LGSOC). We also advanced multiple clinical programs across several RAS/MAPK pathway-driven solid tumor cancers,” said Dan Paterson, president and chief executive officer at Verastem Oncology. “In 2026, we are well-positioned to drive sustainable growth with our successful commercial launch and to accelerate our clinical path for VS-7375, our potential best-in-class oral KRAS G12D (ON/OFF) inhibitor, with several important data readouts and preparations for potential registration-directed clinical trials.”
Financial Update1
Based on preliminary, unaudited results, Verastem expects AVMAPKI FAKZYNJA CO-PACK net product revenues of approximately $17.5 million for the fourth quarter of 2025 and approximately $30.9 million for the full year 2025. Full year 2025 net product revenue reflects the launch period of May, following U.S. Food and Drug Administration (FDA) approval, through December 2025.
The Company also announced that as of January 25, 2026 outstanding cash warrants had been exercised, netting $29.4 million. No cash exercise warrants remain outstanding.
As of December 31, 2025, the Company had cash, cash equivalents, and investments (unaudited) of $205 million; on a pro forma basis, taking into consideration the net proceeds of the cash exercise warrants, cash, cash equivalents and investments were $234 million. With its ongoing product revenue, recent equity financing, and exercise of the remaining cash warrants, the Company expects its cash runway to extend into the first half of 2027.
Given the growth trajectory of the AVMAPKI FAKZYNJA CO-PACK, Verastem anticipates the LGSOC commercial launch and development program will be self-sustaining by the second half of 2026.
2026 Priorities
In 2026, Verastem will continue to focus on maximizing the commercial launch of AVMAPKI FAKZYNJA CO-PACK while advancing its differentiated pipeline targeting RAS/MAPK-pathway driven cancers to create sustainable long-term growth:
AVMAPKI FAKZYNJA CO-PACK (avutometinib; defactinib) – the first treatment specifically approved by the FDA for adults with KRAS-mutated recurrent LGSOC who have received prior systemic therapy. The combination is being evaluated in an ongoing international Phase 3 trial, RAMP 301, in recurrent LGSOC with or without a KRAS mutation. The trial is fully enrolled, as of December 2025, and will serve as a confirmatory study for the initial indication and has the potential to expand the indication regardless of KRAS mutation status. The results will also be leveraged for potential geographic expansion.
The Company announced today updated data from the ongoing RAMP201J Phase 2 clinical trial in Japan evaluating the combination in patients with LGSOC with or without a KRAS mutation. As of the data cutoff on January 30, 2026, 16 patients were efficacy evaluable by investigator assessment, having at least one post-baseline assessment with a median follow-up of 10 months. Of the 16 total patients, a confirmed overall response rate (ORR) of 38% (6/16) was achieved. Among patients with KRAS-mutated recurrent LGSOC, the confirmed ORR was 57% (4/7) and the disease control rate (DCR) was 100% (7/7). Among patients with KRAS wild-type recurrent LGSOC, the confirmed ORR was 22% (2/9) and the DCR was 89% (8/9). Of the 16 patients enrolled, 11 patients remain on treatment. No patients discontinued due to an adverse event. The safety profile was similar to previously reported data.
Verastem expects to:
Maximize adoption of AVMAPKI FAKZYNJA CO-PACK in the U.S. as the treatment of choice at the earliest recurrence, leveraging its robust clinical data.
Report a topline readout of the primary endpoint in the RAMP 301 trial in mid-2027.
Continue to pursue regulatory paths for potential expansion of the product launch into Europe and Japan.
VS-7375 – is an investigational, highly selective and oral KRAS G12D (ON/OFF) inhibitor being evaluated in an international Phase 1/2 trial in advanced KRAS G12D solid tumors. The trial continues to enroll in both the monotherapy dose-escalation and dose-expansion cohorts and multiple dose-escalation combination cohorts in various solid tumors including colorectal cancer (CRC), pancreatic ductal adenocarcinoma (PDAC), and non-small cell lung cancer (NSCLC).
As previously reported, the Company cleared the 400, 600, and 900 mg once daily (QD) dose levels with no dose-limiting toxicities (DLTs) and no major toxicities. The monotherapy expansion cohorts have been initiated, and the cohort sizes have been expanded in second-line (2L) PDAC, 2L/3L NSCLC, and 2L+ tumor agnostic solid tumors, including biliary tract cancer (BTC) and endometrial cancer. The Company cleared the 400 mg QD dose in combination with cetuximab with no DLTs and is currently evaluating the 600 mg QD dose level with cetuximab. The combination dose escalation cohorts were initiated in first-line (1L) NSCLC and 2L PDAC at the end of 2025.
Verastem expects to:
Report an interim update on the Phase 1/2 trial of VS-7375 in 1H 2026.
Select the recommended Phase 2 dose (RP2D) with cetuximab and initiate the CRC combination expansion cohort in 1H 2026.
Engage with the FDA in 1H 2026 to discuss its development path forward, including potential registration-directed clinical trials in PDAC, NSCLC, and CRC.
Complete enrollment in combination dose-escalation cohorts in mid-2026.
Complete enrollment in monotherapy expansion cohorts in 2H 2026.
Select the RP2D and plan to initiate the PDAC and NSCLC combination expansion cohorts in 2H 2026.
Avutometinib Plus Defactinib – is being evaluated in an ongoing RAMP 205 study in combination with standard-of-care chemotherapy in the front line for patients with metastatic PDAC. At the American Society of Clinical Oncology (ASCO) Annual Meeting in 2025, the Company reported that the first 12 patients enrolled to dose level 1 (DL1) in the RAMP 205 study reported an ORR of 83% (10/12). Seventeen additional patients were enrolled in the DL1 expansion between May and August 2025, and with a minimum follow-up of approximately 4 months, the majority of these patients remain on treatment as of January 2026.
Verastem expects to:
Report an update on the safety and efficacy of the RAMP 205 expansion cohort with at least six months of follow-up on all patients in Q2 2026.
1The information presented above is unaudited and reflects preliminary estimates subject to the completion of financial closing procedures and any adjustments that may result from the finalization of the quarter and annual review of the Company’s financial statements by external auditors. Verastem plans to report the final 4Q2025 and full year 2025 results during its fourth quarter 2025 earnings call in early March 2026.
Guggenheim Emerging Outlook: Biotech Summit
The Company’s leadership will participate in a fireside chat at the Guggenheim Emerging Outlook: Biotech Summit on Wednesday, February 11, 2026, at 2:00 pm ET in New York. A live webcast of the fireside chat can be accessed under “Events & Presentations” on the Company’s website at www.verastem.com. A replay of the webcast will be archived on the website for approximately 90 days following the presentation.
About AVMAPKI and FAKZYNJA Combination Therapy
AVMAPKI (avutometinib) inhibits MEK kinase activity while also blocking the compensatory reactivation of MEK by upstream RAF. RAF and MEK proteins are regulators of the RAS/RAF/MEK/ERK (MAPK) pathway. Blocking RAF and/or MEK activates FAK, a key mediator of drug resistance. FAKZYNJA (defactinib) is a FAK inhibitor and together, the avutometinib and defactinib combination was designed to provide a more complete blockade of the signaling that drives the growth and drug resistance of RAS/MAPK pathway-dependent tumors.
The U.S. Food and Drug Administration (FDA) approved AVMAPKI™ FAKZYNJA™ CO-PACK (avutometinib capsules; defactinib tablets) for the treatment of adult patients with KRAS-mutated recurrent LGSOC who have received prior systemic therapy on May 8, 2025. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial. Verastem is conducting RAMP 301 (GOG-3097/ENGOT-ov81/GTG-UK) (NCT06072781), an international Phase 3 confirmatory trial evaluating the combination of avutometinib and defactinib versus standard chemotherapy or hormonal therapy for the treatment of recurrent low-grade serous ovarian cancer (LGSOC) with and without a KRAS mutation. Verastem is also evaluating avutometinib plus defactinib with standard-of-care chemotherapy as a potential treatment in the first-line for patients with advanced pancreatic cancer (RAMP 205; NCT05669482). Avutometinib and defactinib are not approved by the FDA or any other regulatory authority, either in combination or with other therapies, for any of these investigative uses. Neither avutometinib nor defactinib are approved by the FDA or any other regulatory authority on a stand-alone basis for any use.

About VS-7375, an Oral KRAS G12D (ON/OFF) Inhibitor
VS-7375 is a potential best-in-class, potent, and selective oral KRAS G12D dual ON/OFF inhibitor. VS-7375 is the lead program from the Verastem Oncology discovery and development collaboration with GenFleet Therapeutics. Verastem initiated VS-7375-101, an international Phase 1/2 clinical trial, in June of 2025 in the U.S., that is evaluating the safety and efficacy of VS-7375 in patients with advanced KRAS G12D mutant solid tumors. Verastem announced in April 2025 that the U.S. Investigational New Drug (IND) application for VS-7375 was cleared.
About the GenFleet Therapeutics Collaboration
The collaboration with GenFleet Therapeutics aims to advance three oncology discovery programs related to RAS/MAPK pathway-driven cancers. The collaboration provides Verastem with an exclusive option to obtain a license for each of the three compounds in the collaboration after the successful completion of pre-determined milestones in a Phase 1 trial. Verastem selected VS-7375 (also known as GFH375), an oral KRAS G12D (ON/OFF) inhibitor, as its lead program in December 2023 and the license for VS-7375 that was exercised in January 2025 is the first one from this collaboration. The licenses would give Verastem development and commercialization rights outside the GenFleet markets of mainland China, Hong Kong, Macau, and Taiwan.
