Verastem, Inc. (Nasdaq: VSTM) (also known as Verastem Oncology), a biopharmaceutical company committed to advancing new medicines for patients battling cancer, today reported financial results for the three months and full year ending December 31, 2020, and highlighted its key corporate objectives for 2021 and early 2022.

“We are encouraged as we continue to gain greater understanding of the profile of our RAF/MEK inhibitor VS-6766 and its role in blocking multiple nodes in the RAS pathway without the resistance and tolerability issues that have historically been challenges. Based on its unique profile, we believe that VS-6766 could play a significant role in combination therapy across multiple tumor types and where patients need better options,” said Brian Stuglik, Chief Executive Officer of Verastem Oncology. “We have a strong balance sheet to execute on our corporate objectives and report across multiple key catalysts. Our annual spend is projected to be approximately $50 million for 2021, and we still anticipate being comfortably funded until at least 2024.”

In Q4 2020, the Company advanced VS-6766 into two Phase 2 registration-directed clinical studies: RAMP 201 in patients with recurrent low-grade serous ovarian cancer (LGSOC) and RAMP 202 in patients with KRAS-G12V mutant non-small cell lung cancer (NSCLC). Both are evaluating VS-6766 with the Company’s FAK inhibitor, defactinib. The combination of VS-6766 and defactinib had been found to be clinically active in patients with KRAS mutant tumors through an ongoing investigator-initiated Phase 1/2 FRAME study. The FRAME study is evaluating the combination in patients with recurrent LGSOC, KRAS mutant NSCLC, KRAS-G12V mutant NSCLC, pancreatic cancer and KRAS mutant endometrioid cancer.

“In the FRAME study, additional patients with recurrent LGSOC have now responded to treatment with clinically meaningful results for patients with KRAS wild-type tumors, which represents approximately 70% of all LGSOC patients. The results add to the robust and durable responses that have been demonstrated for patients with KRAS mutations,” said Jonathan Pachter, Chief Scientific Officer of Verastem Oncology. “The majority of LGSOC cases are RAS pathway-driven, and these new data support the premise that VS-6766 could be a treatment for all LGSOC patients. Therefore, we are expanding the selection phase of our company-sponsored RAMP 201 study to now include both patient populations (KRAS mutant and KRAS wild-type) to determine the optimal go-forward regimen for both.”

In an updated December 2020 read-out of the FRAME study LGSOC cohort (n=24), the overall response rate (ORR) is 52% (11 of 21 response evaluable patients), with KRAS mutant ORR at 70% (7 of 10 response evaluable patients), KRAS wild-type ORR at 44% (4 of 9 response evaluable patients) and KRAS status undetermined ORR at 0% (0 of 2 response evaluable patients). As reported previously, the most common side effects seen in the study were rash, creatine kinase elevation, nausea, hyperbilirubinemia and diarrhea, most being NCI CTC Grade 1/2 and all were reversible. The data from the LGSOC cohort are anticipated to be presented at a major medical meeting during the second half of 2021.

Recent Corporate Highlights

• Phase 2 registration-directed (RAMP 201) study underway investigating VS-6766 alone and in combination with defactinib for the treatment of patients with recurrent LGSOC.
  
  
  • Supportive updated data from LGSOC cohort of the investigator-sponsored Phase 1/2 FRAME study continues to show encouraging clinical activity, durability and a favorable safety profile in both the overall patient population and in the subgroup of patients with KRAS mutant LGSOC, including patients who had previously progressed following treatment with a MEK inhibitor.
    
    
  • Ongoing data from the FRAME study are demonstrating clinically meaningful results in patients with KRAS wild-type LGSOC in addition to those with KRAS mutation as more patients have had an opportunity to respond to treatment.

• Phase 2 registration-directed (RAMP 202) study underway investigating VS-6766 alone and in combination with defactinib for the treatment of patients with recurrent KRAS-G12V mutant NSCLC.

• Closed COPIKTRA sale to Secura Bio, Inc. (Secura) in a deal valued at up to $311 million, plus royalties.

• Ended 2020 with $147.2 million in cash, cash equivalents and investments.

Upcoming Milestones and Key Priorities for 2021-2022

LGSOC

• Amend RAMP 201 protocol to add enrollment of patients with KRAS wild-type LGSOC in selection phase.
• Report top-line results from the selection phase of RAMP 201 and commence expansion phase during the first half of 2022.
• Report updated data from Phase 1/2 FRAME study LGSOC cohort, including the KRAS wild-type population, during the second half of 2021.

NSCLC

• Report top-line results from the selection phase of RAMP 202 and commence expansion phase during the first half of 2022.
• Updated data from the Phase 1/2 FRAME study NSCLC cohort will be presented by the investigator at the 2021 American Association for Cancer Research (AACR) Annual Meeting. The presentation will include an update on all variants of mutant KRAS, including further updates on the KRAS G12V NSCLC patients who had been previously highlighted. As no new KRAS G12V patients were enrolled in the original FRAME study, a KRAS G12V-specific NSCLC cohort of FRAME has been opened in addition to the Company-sponsored RAMP 202 registration-directed trial.

Corporate and Financial

• Expect 2021 annual operating expenses of approximately $50 million.

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, 2020 and 2019 are included in the tables accompanying this press release after the unaudited condensed consolidated financial statements.

About VS-6766

VS-6766 (formerly known as CH5126766 and RO5126766) is a unique inhibitor of the RAF/MEK signaling pathway. In contrast to other MEK inhibitors in development, VS-6766 blocks both MEK kinase activity and the ability of RAF to phosphorylate MEK. This unique mechanism allows VS-6766 to block MEK signaling without the compensatory activation of MEK that appears to limit the efficacy of other inhibitors.

About Defactinib

Defactinib (VS-6063) is an oral small molecule inhibitor of FAK and PYK2 that is currently being evaluated as a potential combination therapy for various solid tumors. The Company has received Orphan Drug designation for defactinib in ovarian cancer and mesothelioma in the US, EU and Australia. Preclinical research by Verastem Oncology scientists and collaborators at world-renowned research institutions has described the effect of FAK inhibition to enhance immune response by decreasing immuno-suppressive cells, increasing cytotoxic T cells, and reducing stromal density, which allows tumor-killing immune cells to enter the tumor.1,2

About the VS-6766/Defactinib Combination

RAS mutant tumors are present in ~30% of all human cancers, have historically presented a difficult treatment challenge and are often associated with significantly worse prognosis. Challenges associated with identifying new treatment options for these types of cancers include resistance to single agents, identifying tolerable combination regimens with MEK inhibitors and new RAS inhibitors in development addressing only a minority of all RAS mutated cancers.

The combination of VS-6766 and defactinib has been found to be clinically active in patients with KRAS mt tumors. In an ongoing investigator-initiated Phase 1/2 FRAME study, the combination of VS-6766 and defactinib is being evaluated in patients with LGSOC, KRAS mt NSCLC and colorectal cancer (CRC). The FRAME study was expanded to include new cohorts in pancreatic cancer, KRASmt endometrioid cancer and KRAS-G12V NSCLC. Verastem Oncology is also supporting an investigator-initiated Phase 2 trial evaluating VS-6766 with defactinib in patients with metastatic uveal melanoma.

Verastem Oncology has initiated Phase 2 registration-directed trials of VS-6766 with defactinib in patients with recurrent LGSOC and in patients with recurrent KRAS-G12V NSCLC as part of its RAMP (Raf And Mek Program).
