The data are being presented in an oral session at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting (see Abstract #4013 and accompanying presentation) by Peter Vu, M.D., M.H.A., Associate Professor of Medicine and Medical Director, Cancer Quality, GI Medical Oncology, Experimental Therapeutics & Cellular and Regenerative Medicine at UC San Diego Moores Cancer Center. The presentation showcases data from an expanded cohort totaling 55 first-line pancreatic cancer patients. “As pancreatic cancer clinicians, we are urgently seeking therapies capable of meaningfully extending survival while preserving patients’ quality of life,” said Daniel Ahn, D.O., Mayo Clinic Arizona, an investigator on the Phase 2a trial of atebimetinib. “The median overall survival of 17.3 months observed in this study is incredibly encouraging relative to historical outcomes in first-line metastatic pancreatic cancer. Equally important, atebimetinib demonstrated a notably favorable tolerability profile, with limited severe treatment-related toxicities and encouraging indicators of preserved functional status, including weight stability – key characteristics for treatments balancing durable clinical benefit and patient experience. Data from this expanded cohort reinforce atebimetinib’s strong potential in first-line pancreatic cancer.” This open-label, single-arm Phase 2a trial eva...
