Brian Stuglik will retire from the CEO role and remain a member of the Board of Directors. These changes will be effective August 1, 2023, allowing for a smooth leadership transition.

“On behalf of the Board of Directors, I would like to thank Brian for his leadership during which the Company emerged as a recognized innovator in the development of RAS pathway treatments,” stated Michael Kauffman, Chairman of the Board of Directors. “As part of the Board’s succession planning for Brian’s retirement, we recognized Dan’s extensive biopharmaceutical leadership experience, his significant role in the progress of the Company and his vision for the future. We are pleased to announce this well-deserved promotion to Chief Executive Officer.”

Dan Paterson joined Verastem Oncology in 2011 and has served as Chief Operating Officer since 2014 and President since 2019. He has more than 30 years of experience at healthcare and biotechnology companies. At Verastem Oncology, he spearheaded the acquisition of lead compound avutometinib and strategic direction to accelerate the program’s advancement. The combination of avutometinib and defactinib received Breakthrough Therapy Designation from the U.S. Food and Drug Administration (FDA) for recurrent low-grade serous ovarian cancer (LGSOC) and is in late-stage development.

“I am energized to build on the accomplishments we have made as a management team and to lead Verastem Oncology forward in establishing avutometinib as a backbone therapy for RAS pathway-driven tumors,” said Dan Paterson. “As we are dedicated to bringing new oncology treatments to patients with high unmet medical need, our ability to deliver on that purpose will continue to be what’s most important at Verastem Oncology. Having worked closely with Brian and the Board of Directors, I look forward to continuing our collaboration as we prepare for potential commercialization in LGSOC. I am proud to work with our dedicated team to ensure progress is made as quickly and effectively as possible.”

Brian Stuglik has been the CEO of Verastem Oncology since 2019 and a member of the Board of Directors since 2017. He has been instrumental in the transformation of the organization to become a leader in the development of RAS-pathway treatments with a strong pipeline and financial position. As part of his role on the Board, he will also now be leading the Commercialization Committee.

“It's been a privilege to lead Verastem Oncology alongside the experienced management team in setting the foundation to be a leader in the treatment of RAS pathway cancers. I look forward to continuing to support the Company’s future success as a member of its Board of Directors,” said Brian Stuglik, CEO of Verastem Oncology. “As the Company moves toward the first potential FDA approval of a therapy for LGSOC and further advances its pipeline, Dan’s experience and leadership will be instrumental in delivering on the next phase of Verastem Oncology’s trajectory.”

About Avutometinib (VS-6766)

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 pathway inhibition. Avutometinib is currently in late-stage development.

In contrast to other MEK 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 inhibitors. The U.S. Food and Drug Administration granted Breakthrough Therapy designation for the combination of Verastem Oncology’s investigational RAF/MEK clamp avutometinib, 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.

Verastem Oncology is currently conducting clinical trials with its RAF/MEK clamp avutometinib in RAS pathway-driven tumors as part of its (Raf And Mek Program). RAMP 201 is a registration-directed trial of avutometinib alone and in combination with defactinib in patients with recurrent LGSOC. Verastem Oncology has established clinical collaborations with Amgen and Mirati to evaluate LUMAKRAS™ (sotorasib) and KRAZATI™ (adagrasib) in combination with avutometinib in KRAS G12C mutant NSCLC as part of the RAMP 203 and RAMP 204 trials, respectively. Supported by the “Therapeutic Accelerator Award” Verastem Oncology received from PanCAN, the Company is conducting RAMP 205, a Phase 1b/2 clinical trial evaluating avutometinib and defactinib with gemcitabine/nab-paclitaxel in patients with front-line metastatic pancreatic cancer.
