Eli Lilly gets USFDA Breakthrough Therapy designation for olomorasib with Keytruda for lung cancer

Breakthrough Therapy designation aims to expedite the development and review of drugs that are intended to treat a serious condition when preliminary clinical evidence indicates that the drug may demonstrate substantial improvement on a clinically significant endpoint(s) over already available therapies that have received full FDA approval. "The Breakthrough Therapy designation recognizes the potential for olomorasib to be a meaningful treatment advance and highlights the continued unmet need for improved options for patients with KRAS G12C-mutant NSCLC, particularly in the first-line setting in combination with standard-of-care immunotherapy," said David Hyman, M.D., Lilly chief medical officer. "We look forward to presenting updated data from the olomorasib development program in significantly more patients and with longer follow-up at WCLC and continuing to investigate olomorasib in combination with immunotherapy-based regimens in a variety of treatment settings across the Phase 3 SUNRAY-01 and SUNRAY-02 studies." The FDA Breakthrough Therapy designation is based on encouraging results from the Phase 1/2 LOXO-RAS-20001 trial and the dose optimization portion of the Phase 3 SUNRAY-01 trial. Updated results from an integrated analysis from these studies will be presented at the 2025 World Conference on Lung Cancer (WCLC) hosted by the International Association for the Study of Lung Cancer (IASLC), taking place Sept. 6 - 9 in Barcelona, Spain. In an oral presentation (Abstract #MA02.06), Lilly will report on an integrated analysis of efficacy and safety results in patients with KRAS G12C-mutant NSCLC who received olomorasib plus pembrolizumab as first-line treatment in the dose optimization cohorts of the Phase 1/2 LOXO-RAS-20001 study and Phase 3 SUNRAY-01 study. These data will be shared in an oral presentation during the New Treatment Strategies in Other Than EGFR-Positive Tumors session on Sunday, Sept. 7, 2025, from 12-1:15 p.m. Central European Summer Time (CEST). In a second oral presentation (Abstract #OA08.02), Lilly will report results of an integrated analysis in patients with KRAS G12C-mutant advanced or metastatic NSCLC who received olomorasib in combination with chemoimmunotherapy (pembrolizumab, pemetrexed and platinum) as a first-line treatment in the Phase 1/2 LOXO-RAS-20001 trial and safety lead-in for the Phase 3 SUNRAY-01 trial. These data will be shared in an oral presentation during the Improving Outcomes in EGFR and KRAS Mutant Tumors, More is Better session on Monday, Sept. 8, 2025, from 12-1:15 p.m. CEST.
