Clinical Collaborations and Investigator-Sponsored Trial Programs Ongoing in Additional Areas of High Unmet Need

BOSTON--(BUSINESS WIRE)--Mar. 28, 2022-- Verastem Oncology (Nasdaq: VSTM), a biopharmaceutical company committed to advancing new medicines for patients with cancer, today reported financial results for the three months and full year ended December 31, 2021, and highlighted recent progress.

“We anticipate a catalyst-driven year and are well-positioned to maximize the potential of VS-6766 as a backbone therapy across RAS pathway-driven solid tumors in order to bring new solutions to patients in areas of high unmet need. Our recent debt facility adds flexibility to our financial strength and is expected to support the continued development and potential commercial launches of VS-6766 and defactinib, including building on our breakthrough therapy designation in low-grade serous ovarian cancer,” said Brian Stuglik, Chief Executive Officer of Verastem Oncology. “We plan to report results from the selection phase of RAMP 201, our lead program in patients with low-grade serous ovarian cancer, regardless of KRAS status, during the second quarter. And, as part of our non-small cell lung cancer program, we are targeting KRAS mutant patient subpopulations across four clinical trials and we are anticipating initial readouts from three NSCLC studies, including RAMP 202 with defactinib, the investigator-sponsored study with everolimus, and RAMP 203 with LUMAKRAS^TM (sotorasib) this year.”

Fourth Quarter 2021 and Recent Highlights

Verastem’s lead drug candidate VS-6766 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 pathway inhibition.

Low Grade Serous Ovarian Cancer (LGSOC)

• Planned enrollment is complete in the selection phase (Part A; n=64) of the registration-directed Phase 2 RAMP 201 study investigating VS-6766 alone or in combination with defactinib for the treatment of recurrent LGSOC. Verastem remains on track to report topline results from Part A during the second quarter of 2022, following discussions with regulatory authorities.
• Enrollment has commenced in the expansion phase (Part B) of RAMP 201, with both treatment arms (VS-6766 alone and in combination with defactinib) currently advancing in all patients. Verastem expects to complete enrollment in Part B during the second half of 2022.

KRAS Mutant Non-Small Cell Lung Cancer (NSCLC)

• Planned enrollment is now complete in the selection phase (Part A; n=32) of the registration-directed RAMP 202 study investigating VS-6766 alone and in combination with defactinib in patients with KRAS G12V mutant NSCLC. The Company expects to report topline results from Part A and initiate Part B during the second half of 2022, following discussions with regulatory authorities.
• Based on preclinical rationale, Verastem has added BRAF mutant cohorts to the RAMP 202 study in order to efficiently evaluate VS-6766 with defactinib in BRAF-mutant NSCLC. In Part A of the study, the Company expects to enroll two cohorts comprised of 15 patients each to evaluate the combination in patients with V600E or non-V600E BRAF mutations, respectively. These cohorts are open and enrolling.
• The Company entered into two clinical agreements to study VS-6766 in combination with KRAS G12C inhibitors in patients with KRAS G12C-mutant NSCLC, including patients who have progressed on a KRAS G12C inhibitor. Initial results from the ongoing Phase 1/2 RAMP 203 study evaluating VS-6766 in combination with Amgen’s LUMAKRAS^TM (sotorasib) are expected to be reported during the second half of 2022. Initiation of the Phase 1/2 RAMP 204 study evaluating VS-6766 in combination with Mirati’s adagrasib is expected during the second quarter of 2022.

Corporate Updates

• Secured debt facility with Oxford Finance LLC for up to $150 Million. Under the terms of the credit facility with Oxford Finance LLC, Verastem drew an initial $25 million term loan at closing. The Company has the ability to access up to an additional $125 million in a series of tranches, $75 million of which are based on certain pre-determined milestones and $50 million at the lender’s discretion.

• With the credit facility and expected milestones related to the sale of COPIKTRA® (duvelisb) to Secura Bio Inc. (Secura) in 2020, the Company expects to have a cash runway through 2025 to support the continued development and potential commercial launches of VS-6766 and defactinib.

• In the first quarter of 2022, Secura Bio Inc.’s (Secura) sublicensee, CSPC Pharmaceutical Group Limited, obtained drug registration approval for duvelisib granted by the National Medical Products Administration of the People’s Republic of China for the treatment of adult patients with relapsed or refractory follicular lymphoma after at least two prior systematic therapies. This entitles Verastem to a $2.5 million milestone payment from Secura, pursuant to the sale of COPIKTRA® (duvelisb) to Secura in 2020.

• Appointed Michelle Robertson to join the Verastem Board of Directors. Ms. Robertson is the Chief Financial Officer at Editas Medicine and brings more than 25 years of finance and commercial operations leadership to the Board. Timothy Barberich will be retiring from the Board as of March 31, 2022. Verastem appreciates his significant contributions since his appointment in March, 2014.

• Appointed Channing Der, PhD, Sarah Graham Kenan Distinguished Professor at the University of North Carolina at Chapel Hill to the Company’s Scientific Advisory Board.

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) income and non-GAAP net (loss) income 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, 2021 and 2020 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 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 pathway inhibition. VS-6766 is currently in late-stage development.

In contrast to other MEK inhibitors, 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. The U.S. Food and Drug Administration granted Breakthrough Therapy designation for the combination of Verastem Oncology’s investigational RAF/MEK inhibitor VS-6766, with defactinib, its FAK inhibitor, for the treatment of all patients with recurrent low-grade serous ovarian cancer (LGSOC) regardless of KRAS status after one or more prior lines of therapy, including platinum-based chemotherapy.¹

Verastem Oncology is conducting Phase 2 registration-directed trials of VS-6766 alone and with defactinib in patients with recurrent LGSOC and in patients with recurrent KRAS G12V-mutant NSCLC as part of its RAMP (Raf And Mek Program) clinical trials, RAMP 201 and RAMP 202, respectively. Verastem Oncology has also established clinical collaborations with Amgen and Mirati to evaluate LUMAKRAS™ (sotorasib) and adagrasib in combination with VS-6766 in KRAS G12C-mutant NSCLC as part of the RAMP 203 and RAMP 204 trials, respectively.
