Mirati Therapeutics Reports Collab With Sanofi For Phase 1/2 Study Evaulating Combo Of Adagrasib With SHP2 Inhibitor In KRAS G12C-Mutated Lung Cancer

Mirati Therapeutics, Inc. (NASDAQ:MRTX), a clinical-stage targeted oncology company, today announced a non-exclusive clinical collaboration agreement with Sanofi to evaluate the combination of adagrasib, the Company's investigational KRASG12C inhibitor, with Sanofi's investigational SHP2 inhibitor SAR442720, also known as RMC-4630. The Phase 1/2 dose escalation and expansion study will evaluate the combination in patients with previously-treated non-small cell lung cancer (NSCLC) and KRASG12C mutations.

"Mirati is aggressively advancing a broad adagrasib development program, which includes pursuing novel combination approaches including through this collaboration with Sanofi," said Charles M. Baum, M.D., Ph.D., president, founder and head of research and development, Mirati Therapeutics, Inc. "There is strong scientific rationale for combining a SHP2 inhibitor with adagrasib, which may help optimize clinical outcomes for patients with KRASG12C-dependent tumors."

SHP2 is upstream of KRAS and mediates cellular signaling through the RAS/MAP kinase pathway and is frequently overactive in various types of cancer. KRASG12C inhibition and SHP2 inhibition have complementary mechanisms of action and have demonstrated additive anti-tumor activity in pre-clinical models.

Under the terms of the agreement, Sanofi will be responsible for sponsoring and operating the Phase 1/2 study, and jointly with Mirati, will oversee and share costs of the study.
