Amgen Announced on Sunday European Commission Approved Lumykras for Patients With KRAS G12C-mutated Advanced Non-small Cell Lung Cancer

Amgen (NASDAQ:AMGN) today announced that the European Commission (EC) has granted conditional marketing authorization for LUMYKRAS(r) (sotorasib), a first-in-class KRASG12C inhibitor,for the treatment of adults with advanced non-small cell lung cancer (NSCLC) with KRAS G12C mutation and who have progressed after at least one prior line of systemic therapy. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

"The approval of LUMYKRAS, the first and only targeted therapy for KRAS G12C-mutated NSCLC with proven efficacy, has the potential to transform treatment outcomes for people in the European Union living with this notoriously difficult-to-treat cancer," said David M. Reese, M.D., executive vice president of Research and Development at Amgen. "Amgen's landmark scientific discovery allowed investigators to advance the first KRASG12Cinhibitor into the clinic, and we look forward to bringing this critical innovation to more patients across the globe."

The EC decision follows the recommendation for approval by the Committee for Medicinal Products for Human Use (CHMP) and is based on the positive results from the Phase 2 CodeBreaK 100 clinical trial in NSCLC, the largest trial conducted to date for patients with the KRAS G12C mutation. LUMYKRAS 960 mg, administered orally once-daily, demonstrated an objective response rate of 37.1% (95% CI: 28.6-46.2) and a median duration of response (DoR) of 11.1 months. The most common adverse reactions were diarrhea (34%), nausea (25%), and fatigue (21%). The most common severe (grade3) adverse reactions were increased alanine aminotransferase level (ALT; 5%), increased aspartate aminotransferase (AST; 4%), and diarrhea (4%).

NSCLC accounts for approximately 84% of the 2.2 million new lung cancer diagnoses globally each year, including approximately 400,000 new cases in Europe 1,2 KRASG12C is one of the most prevalent driver mutations in NSCLC, with about 13-15% of European patients with non-squamous NSCLC having theKRASG12C mutation.3,4 With EC approval, and subject to local reimbursement applications, clinicians in all European Union member countries, as well as Norway, Iceland, and Liechtenstein, will be able to offer LUMYKRAS to appropriate patients with NSCLC.
