Amgen today announced the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for sotorasib, an investigational KRASG12C inhibitor for the treatment of patients with KRAS G12C-mutated locally advanced or metastatic non-small cell lung cancer (NSCLC), as determined by an FDA-approved test, following at least one prior systemic therapy. 

"Sotorasib was the first KRASG12C inhibitor to enter the clinic and now is on track to potentially be the first approved targeted therapy for patients with advanced NSCLC harboring the KRAS G12C mutation. In the U.S., about 13% of patients with NSCLC have the KRAS G12C mutation and face a significant unmet need," said David M. Reese, M.D., executive vice president of Research and Development at Amgen. "This submission, along with these other important regulatory achievements, underscore Amgen's commitment to bringing this potential treatment option to patients as quickly as possible."

The NDA is being reviewed by the FDA under its Real-Time Oncology Review (RTOR) pilot program, which aims to explore a more efficient review process that ensures safe and effective treatments are made available to patients as early as possible. 

The submission is supported by positive Phase 2 results in patients with locally advanced or metastatic NSCLC from the CodeBreaK 100 clinical study, whose cancer had progressed despite prior treatment with chemotherapy and/or immunotherapy. In the study, treatment with sotorasib provided durable anticancer activity with a positive benefit-risk profile. These results will be presented at the International Association for the Study of Lung Cancer (IASLC) 2020 World Conference on Lung Cancer (WCLC) Presidential Symposium in January 2021.

About Sotorasib
Amgen has taken on one of the toughest challenges of the last 40 years in cancer research by developing sotorasib, an investigational KRASG12C inhibitor. Sotorasib was the first KRASG12C inhibitor to enter the clinic and is being studied in the broadest clinical program exploring 10 combinations with global sites spanning four continents. In just over two years, the sotorasib clinical program has established the deepest clinical data set with more than 600 patients studied across 13 tumor types.

Sotorasib has demonstrated a positive benefit-risk profile with fast, deep, and durable anti-cancer activity in patients with advanced NSCLC harboring the KRAS G12C mutation with a once-daily oral formulation.  Promising responses have also been observed in multiple other solid tumors.

KRAS G12C is the most common KRAS mutation in NSCLC. In the U.S., about 13% of patients with NSCLC harbor the KRAS G12C mutation. There are a high unmet need and poor outcomes in the second-line treatment of KRAS G12C-driven NSCLC and, currently, there are no KRASG12C targeted therapies approved.

About CodeBreaK
The CodeBreaK clinical development program for Amgen's investigational drug sotorasib is designed to treat patients with an advanced solid tumor with the KRAS G12C mutation and address the longstanding unmet medical need for these cancers. As the most advanced KRAS G12C clinical development program, CodeBreaK has enrolled more than 600 patients across 13 tumor types since its inception.

CodeBreaK 100, Phase 1 and 2, first-in-human, open-label multicenter study, enrolled patients with KRAS G12C-mutated solid tumors. Eligible patients must have received a prior line of systemic anticancer therapy, consistent with their tumor type and stage of the disease. The primary endpoint for the Phase 2 study was centrally assessed objective response rate. The Phase 2 trial in NSCLC enrolled 126 patients, 123 of whom had centrally evaluable lesions by RECIST at baseline. The Phase 2 trial in colorectal cancer (CRC) is fully enrolled and topline results are expected in 2021.

A global Phase 3 randomized active-controlled study comparing sotorasib to docetaxel in patients with KRAS G12C-mutated NSCLC (CodeBreaK 200) is currently recruiting. Amgen also has several Phase 1b combination studies across various advanced solid tumors (CodeBreaK 101) open for enrollment.
