BOSTON--(BUSINESS WIRE)--Verastem Oncology (Nasdaq: VSTM), a biopharmaceutical company committed to advancing new medicines for patients with RAS/MAPK pathway-driven cancers, today announced business updates and reported financial results for the third quarter ended September 30, 2025.
"Our performance in Q3, which was the first full quarter since our accelerated approval and launch of AVMAPKI FAKZYNJA CO-PACK, exceeded expectations with net revenue of over $11 million and demonstrated the strength of our growing commercial business and consistent adoption by both academic and community oncologists for the first treatment approved by the FDA specifically for patients with KRAS-mutated recurrent LGSOC,” said Dan Paterson, president and chief executive officer of Verastem Oncology. “As we continue to build on this momentum and the fundamentals we have put into place to guide our commercial business, we’re simultaneously advancing our broader strategic priorities, and are very pleased with the progress of our clinical pipeline programs. Particularly for our KRAS G12D (ON/OFF) inhibitor, VS-7375, preliminary safety, tolerability, and anti-tumor activity are promising, and we believe in line as a potential best-in-class option for patients with pancreatic, lung, and other KRAS G12D-mutated solid tumor cancers. As we move ahead with opening the combination cohort with VS-7375 and cetuximab, we look forward to several important data readouts in the first half of 2026 that we believe will further demonstrate the breadth of our RAS/MAPK pathway-driven approach.”
Third Quarter 2025 and Recent Updates
AVMAPKI™ FAKZYNJA™ CO-PACK (avutometinib in combination with defactinib) U.S. Launch
Achieved net product revenue of $11.2 million in the first full quarter of the launch.
Prescriptions for patients are being received from both academic and community centers, including both repeat prescriptions from physicians prescribing to multiple patients and refills for individual patients.
There has been broad payer coverage and reimbursement since launch.
Avutometinib and Defactinib Combination in Low-Grade Serous Ovarian Cancer (LGSOC)
In the ongoing Phase 3 RAMP 301 confirmatory trial, planned enrollment of the targeted 270 patients was completed a full quarter early.
A pre-planned Interim Analysis (IA) by an Independent Data Monitoring Committee (IDMC) was conducted for RAMP 301, and the IDMC recommended a modest one-time increase in enrollment. Based on the current total enrollment achieved to date, an additional 29 patients will be added across KRAS mutation status. The Company remains blinded to the IA results.
Preliminary safety and efficacy data from the Phase 2 RAMP 201J trial in Japan was accepted as an E-Poster (EP228/ #371) at the International Gynecologic Cancer Society (IGCS) 2025 Annual Meeting. In the published abstract, with a data extract date of April 11, 2025, no dose limiting toxicities were observed, and avutometinib and defactinib drug exposure levels were comparable to those observed in the global RAMP-201 study. Additional data, including efficacy (response rates) and updated safety will be available on November 5, 2025, when the embargo lifts.
Key Milestone:
Expect to complete patient enrollment of the IDMC recommended increase in Q1 2026.
VS-7375, an Oral KRAS G12D (ON/OFF) Inhibitor, in Advanced Solid Tumors
Announced a preliminary update on the Phase 1/2a monotherapy dose escalation trial of VS-7375 in patients with previously treated advanced KRAS G12D mutant solid tumors on Oct. 23, 2025. In the study, VS-7375 cleared both the 400 mg daily (QD) and the 600 mg QD monotherapy doses with no dose-limiting toxicities (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 pancreatic ductal adenocarcinoma ( PDAC ) and non-small cell lung cancer ( NSCLC) by our partner, GenFleet Therapeutics, in its ongoing Phase 1/2 clinical study in China evaluating VS-7375 (known as GFH375). The Company’s dose escalation study continues with evaluation of the monotherapy 900 mg QD dose level. 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 are still on treatment. The remaining patients receiving either the 400 mg QD or 600 mg QD doses have not yet reached their first response assessment.

The Company also announced it has initiated patient enrollment for the first dose escalation combination cohort evaluating VS-7375 with cetuximab in patients with advanced solid tumors, including colorectal cancer.
Announced updated data from partner GenFleet Therapeutics’ Phase 1/2 study of GFH375 in China that was featured in a late-breaking oral presentation at the European Society for Medical Oncology (ESMO) Congress on October 19, 2025. Among 59 heavily pre-treated patients with PDAC who received one or more prior lines of therapy, an overall response rate (ORR) of 41% was achieved at the monotherapy recommended Phase 2 dose (RP2D) of 600 mg QD. A disease control rate (DCR) of 96.7% (57/59) was also reported with the majority of patients (91.5%) experiencing a reduction in target lesions. Overall survival (OS) observed at month four was 92.2%. The median OS was not reached as of the data cutoff, with a median follow-up time of 5.65 months. The median progression-free survival (mPFS) was 5.52 months with a median follow-up time of 5.65 months and a 4-month PFS rate of 78.2%. At evaluation, 31 (47%) patients were still on treatment with the longest duration of treatment eclipsing one year (367 days). The safety profile in PDAC patients was consistent with the previously reported data at recent medical congresses.

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 and nine months ended September 30, 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 in combination with defactinib and other agents as a potential treatment for patients with advanced pancreatic cancer (RAMP 205; NCT05669482) and advanced KRAS G12C mutant non-small cell lung cancer (RAMP 203; NCT05074810). 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.
