Fourth Quarter 2023 and Recent Highlights

Avutometinib and Defactinib Combination in Low-Grade Serous Ovarian Cancer (LGSOC)

• Initiated international confirmatory Phase 3 RAMP 301 trial evaluating the avutometinib and defactinib combination versus standard of care chemotherapy or hormonal therapy for the treatment of recurrent LGSOC in December 2023 to support potential full approval.
• Reported results of a planned subgroup analysis of Part A of the Phase 2 RAMP 201 trial evaluating avutometinib and defactinib combination in recurrent LGSOC, which demonstrated promising efficacy in patients regardless of number and class of prior therapies including after poor response to prior therapy at the Annual Global Meeting of the International Gynecologic Cancer Society meeting in November 2023.
• Launched patient and healthcare professional programs, including Let’s Talk About LGSOC, to support clinicians in the diagnosis and management of LGSOC and provide information and resources to patients.
• Received Orphan Drug Designation from the U.S. Food and Drug Administration (FDA) in March 2024 for avutometinib alone or in combination with defactinib for the treatment of all patients with recurrent LGSOC.

Verastem anticipates the following milestones for avutometinib and defactinib combination in LGSOC in 2024:

• On track to submit a rolling New Drug Application (NDA) for Accelerated Approval for the avutometinib and defactinib combination in LGSOC in H1 2024. Preparations for a potential U.S. commercial launch in 2025 are ongoing and plans to initiate discussions with European and Japanese regulatory authorities to address patient needs outside the U.S. continue to advance.
• Plan to announce updated topline data from RAMP 201 trial in LGSOC in H1 2024.

Avutometinib in Combination with KRAS G12C Inhibitors in Non-Small Cell Lung Cancer (NSCLC)

• Received Fast Track designation from the FDA for avutometinib, in combination with Amgen’s G12C inhibitor, LUMAKRAS™ (sotorasib), for the treatment of patients with KRAS G12C-mutant metastatic NSCLC who have received at least one prior systemic therapy and have not been previously treated with a KRAS G12C inhibitor, in January 2024.
• Presented initial results from Phase 1/2 RAMP 203 trial evaluating the efficacy and safety of avutometinib and sotorasib in patients with KRAS G12C-mutant NSCLC who have or have not been previously treated with a KRAS G12C inhibitor at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics in October 2023. The confirmed objective rate of response (ORR) was 25% with responses observed in both KRAS G12C inhibitor resistant and naïve patients, and a recommended Phase 2 dose was selected.
• Added defactinib to RAMP 203 trial of avutometinib with sotorasib based on stronger tumor regressions in KRAS G12C-mutant NSCLC preclinical models when FAKi is added along with G12Ci + avutometinib.

Verastem anticipates the following milestones for avutometinib in combination with KRAS G12C inhibitors in 2024:

• Data updates from patients with KRAS G12C-mutant NSCLC in the Phase 1/2 RAMP 203 trial evaluating avutometinib and sotorasib and the Phase 1/2 RAMP 204 trial evaluating avutometinib and adagrasib are planned for mid-2024.

Avutometinib and Defactinib Combination in Frontline Metastatic Pancreatic Cancer

• Plan to present initial safety and efficacy results from RAMP 205 trial of avutometinib and defactinib in combination with current standard of care gemcitabine and nab-paclitaxel in frontline metastatic pancreatic cancer in H1 2024.

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, 2023 and 2022 are included in the tables accompanying this press release after the unaudited condensed consolidated financial statements.

About the Avutometinib and Defactinib Combination

Avutometinib is a RAF/MEK clamp that induces inactive complexes of MEK with ARAF, BRAF and CRAF potentially creating a more complete and durable anti-tumor response through maximal RAS/MAPK pathway inhibition. In contrast to currently available MEK-only inhibitors, avutometinib blocks both MEK kinase activity and the ability of RAF to phosphorylate MEK. This unique mechanism allows avutometinib to block MEK signaling without the compensatory activation of MEK that appears to limit the efficacy of other MEK-only inhibitors. The U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy designation for the combination of Verastem Oncology’s investigational RAF/MEK clamp avutometinib, with defactinib, a selective FAK inhibitor, for the treatment of all patients with recurrent LGSOC regardless of KRAS status after one or more prior lines of therapy, including platinum-based chemotherapy. Avutometinib alone or in combination with defactinib was also granted Orphan Drug Designation by the FDA for the treatment of LGSOC.

Verastem Oncology is currently conducting clinical trials with its RAF/MEK clamp avutometinib in RAS/MAPK driven tumors as part of its (Raf And Mek Program). RAMP 301 (NCT06072781) is a Phase 3 confirmatory trial evaluating the combination of avutometinib and defactinib versus standard chemotherapy or hormonal therapy for the treatment of recurrent LGSOC. RAMP 201 (NCT04625270) is a Phase 2 registration-directed trial of avutometinib in combination with defactinib in patients with recurrent LGSOC and enrollment has been completed in each of the dose optimization and expansion phases and the low-dose evaluation.

Verastem Oncology has established clinical collaborations with Amgen and Mirati to evaluate LUMAKRAS™ (sotorasib) in combination with avutometinib and defactinib and KRAZATI™ (adagrasib) in combination with avutometinib in KRAS G12C mutant NSCLC as part of the RAMP 203 (NCT05074810) and RAMP 204 (NCT05375994) trials, respectively. Supported by the “Therapeutic Accelerator Award” received from PanCAN, Verastem Oncology is conducting RAMP 205 (NCT05669482), a Phase 1b/2 clinical trial evaluating avutometinib and defactinib with gemcitabine/nab-paclitaxel in patients with front-line metastatic pancreatic cancer.

About GFH375 (VS-7375)

GFH375 (VS-7375) is a potential best-in-class, potent and selective oral KRAS G12D (ON/OFF) inhibitor, identified as the lead program from the Verastem Oncology discovery and development collaboration with GenFleet Therapeutics. GenFleet plans to submit an IND in China for GFH375 (VS-7375) in the first half of 2024, and upon approval GenFleet is expected to initiate a Phase 1 trial in China in the second half of 2024. The collaboration includes three discovery programs, the first being the KRAS G12D inhibitor, and will provide Verastem Oncology with exclusive options to obtain licenses to each of the three compounds in the collaboration after successful completion of pre-determined milestones in Phase 1 trials. The licenses would give Verastem Oncology development and commercialization rights outside of the GenFleet territories of mainland China, Hong Kong, Macau, and Taiwan.
