LUMAKRAS Shows Median Overall Survival of 12.5 Months in Patients With Previously Treated Non-Small Cell Lung Cancer
Data Confirms Rapid, Deep, and Durable Responses With Median Duration of Response of 11.1 Months
Data Presented at ASCO 2021 and Simultaneously Published in New England Journal of Medicine
THOUSAND OAKS, CA, USA I June 4, 2021 I Amgen (NASDAQ: AMGN) today presented data on overall survival, a secondary endpoint, from the Phase 2 results of the CodeBreaK 100 clinical study for LUMAKRASTM (sotorasib) in previously treated patients with non-small cell lung cancer (NSCLC) during the 2021 American Society of Clinical Oncology (ASCO) Annual Meeting. These data were also simultaneously published in the New England Journal of Medicine (NEJM). The publication includes mature overall survival and duration of response data, and results from subgroup and exploratory biomarker analyses.
LUMAKRAS shows a median overall survival (OS) of 12.5 months among 124 evaluable patients, the majority of which were previously treated with both platinum-based chemotherapy and immunotherapy (81%) (data cutoff of March 15, 2021). The results confirmed an objective response rate (ORR) of 37.1%, duration of response (DoR) of 11.1 months and disease control rate (DCR) of 80.6%, with an additional patient achieving complete response (bringing the total to four complete responses and 42 partial responses) compared to previously reported results. The data published in NEJM are updated from results presented at the International Association for the Study of Lung Cancer (IASLC) 2020 World Conference on Lung Cancer (WCLC) held in January 2021 and are based on a longer follow-up time of 15.3 months.
“Patients with KRAS G12C-mutated non-small cell lung cancer face poor outcomes so we are pleased with these overall survival results and the impact LUMAKRAS may have for patients with this devastating mutation,” said David M. Reese, M.D., executive vice president of Research and Development at Amgen. “The results published in the New England Journal of Medicine further confirm the deep and durable responses we have seen with LUMAKRAS throughout the CodeBreaK clinical trial program, the most advanced KRAS G12C clinical trial program with the longest follow-up.”
In exploratory analyses, tumor response to LUMAKRAS was consistently observed across a range of biomarker subgroups, including patient subgroups stratified by baseline PD-L1 expression levels and those with STK11 mutation. In the patient subsets separated by baseline PD-L1 expression (n=86), response and tumor shrinkage were observed across the range of baseline PD-L1 expression levels, with the response rate of 48% for the PD-L1 negative group (TPS <1%). Improved efficacy with LUMAKRAS was seen in STK11-mutant group with concurrent wild-type KEAP1 (n=22) with median progression free survival (PFS) of 11.0 months and median OS of 15.3 months.
“Sotorasib is the first KRASG12C inhibitor to show an overall survival benefit, and the data represent a major step forward for patients with KRAS G12C-mutated non-small cell lung cancer where standard of care options are suboptimal,” said lead author Ferdinandos Skoulidis, M.D., Ph.D., assistant professor of Thoracic/Head and Neck Medical Oncology at The University of Texas MD Anderson Cancer Center. “KRAS has been one of the most challenging therapeutic targets in cancer research, and these practice-changing results give hope to patients with the KRAS G12C mutation who previously had no targeted treatment options.”
LUMAKRAS received approval from the U.S. FDA on May 28, 2021, for the treatment of adult patients with KRAS G12C-mutated locally advanced or metastatic NSCLC, as determined by an FDA-approved test, who have received at least one prior systemic therapy. LUMAKRAS has received accelerated approval based on ORR and DoR. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

About LUMAKRASTM (sotorasib)
Amgen has taken on one of the toughest challenges of the last 40 years in cancer research by developing LUMAKRAS, a KRASG12C inhibitor.1 LUMAKRAS was the first KRASG12C inhibitor to enter the clinic and is being studied in the largest clinical program exploring more than 10 combinations with global investigator sites spanning five continents.
LUMAKRAS has demonstrated a positive benefit-risk profile with rapid, deep and durable anticancer activity in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) harboring the KRAS G12C mutation with a once daily oral formulation. As part of the evaluation for this accelerated approval, FDA is requiring a post-marketing trial to investigate whether a lower dose will have a similar clinical effect.
LUMAKRAS is also being studied in multiple other solid tumors.1
LUMAKRAS was granted Breakthrough Therapy designation in the U.S. and China. In the U.S., LUMAKRAS was reviewed by the FDA under its Real-Time Oncology Review (RTOR), a pilot program that aims to explore a more efficient review process that ensures safe and effective treatments are made available to patients as early as possible. Amgen is participating in the FDA’s Project Orbis initiative and through the initiative, has submitted Marketing Authorization Applications (MAAs) for sotorasib in Australia, Brazil, Canada and the United Kingdom. Additionally, Amgen has submitted an MAA in the EU and New Drug Applications in Japan (J-NDA), Switzerland, South Korea and United Arab Emirates.
LUMAKRASTM (sotorasib) U.S. Indication
LUMAKRASTM is indicated for the treatment of adult patients with KRAS G12C-mutated locally advanced or metastatic non-small cell lung cancer (NSCLC), as determined by an FDA-approved test, who have received at least one prior systemic therapy.
This indication is approved under accelerated approval based on overall response rate (ORR) and duration of response (DOR). Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

About Non-Small Cell Lung Cancer and the KRAS G12C Mutation
Lung cancer is the leading cause of cancer-related deaths worldwide, and it accounts for more deaths worldwide than colon cancer, breast cancer and prostate cancer combined.2 Overall survival rates for NSCLC are improving, but remain poor for patients with advanced disease and 5-year survival is only 7% for those with metastatic disease.3
KRAS G12C is the most common KRAS mutation in NSCLC.4 In the U.S., about 13% of patients with non-squamous NSCLC harbor the KRAS G12C mutation.5 Unmet medical need remains high and treatment options are limited for NSCLC patients with the KRAS G12C mutation whose first-line treatment has failed to work or has stopped working. The outcomes with current therapies are suboptimal with a median progression-free survival of approximately 4 months following second-line treatment of KRAS G12C-mutated NSCLC.6
About CodeBreaK
The CodeBreaK clinical development program for Amgen’s 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 800 patients across 13 tumor types since its inception.
CodeBreaK 100, the Phase 1 and 2, first-in-human, open-label multicenter study, enrolled patients with KRAS G12C-mutant solid tumors. Eligible patients must have received a prior line of systemic anticancer therapy, consistent with their tumor type and stage of disease. The primary endpoint for the Phase 2 study was centrally assessed objective response rate. The Phase 2 trial in NSCLC enrolled 126 patients, 124 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 later in 2021.
A global Phase 3 randomized active-controlled study comparing sotorasib to docetaxel in patients with KRAS G12C-mutated NSCLC (CodeBreaK 200) has completed enrollment. Amgen also has several Phase 1b studies investigating sotorasib monotherapy and sotorasib combination therapy across various advanced solid tumors (CodeBreaK 101) open for enrollment.
