Amgen Announces New Clinical Data Evaluating Novel Investigational KRAS(G12C) Inhibitor In Larger Patient Group At WCLC 2019
Initial data from the Phase 1 study were presented at the 55th Annual Meeting of the
"These new data reinforce the earlier positive response rate we shared at
Among the 34 NSCLC patients enrolled, there were no observed dose-limiting toxicities and no adverse events leading to discontinuation. Twenty-seven of these patients remain on treatment. Of the 34 patients, only nine (26.5%) reported treatment-related adverse events (TRAEs) of grade 1 or 2. Three patients reported grade 3 TRAEs (anemia and diarrhea). There were no grade 4 or higher TRAEs.
"There is a need for targeted treatments for specific driver mutations of cancer that do not have an approved therapy," said
Additional data on AMG 510 will be presented at the
About the Phase 1 Study
The Phase 1, first-in-human, open-label multicenter study enrolled patients with KRAS G12C mutant solid tumors. Eligible patients were heavily pretreated with at least two or more prior lines of treatment, consistent with their tumor type and stage of disease. The primary endpoint is safety, and key secondary endpoints include pharmacokinetics, objective response rate (assessed every six weeks), duration of response and progression-free survival. Patients were enrolled in four dose cohorts: 180 mg, 360 mg, 720 mg and 960 mg, taken orally once a day.
The subject of more than three decades of research, the RAS gene family are the most frequently mutated oncogenes in human cancers.1,2 Within this family, KRAS is the most prevalent variant and is particularly common in solid tumors.2 A specific mutation known as KRAS G12C accounts for approximately 13% of non-small cell lung cancers, 3-5% of colorectal cancers and one to two percent of numerous other solid tumors.3 Approximately 30,000 patients are diagnosed each year in

This news release contains forward-looking statements that are based on the current expectations and beliefs of
No forward-looking statement can be guaranteed and actual results may differ materially from those we project. Discovery or identification of new product candidates or development of new indications for existing products cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate or development of a new indication for an existing product will be successful and become a commercial product. Further, preclinical results do not guarantee safe and effective performance of product candidates in humans. The complexity of the human body cannot be perfectly, or sometimes, even adequately modeled by computer or cell culture systems or animal models. The length of time that it takes for us to complete clinical trials and obtain regulatory approval for product marketing has in the past varied and we expect similar variability in the future. Even when clinical trials are successful, regulatory authorities may question the sufficiency for approval of the trial endpoints we have selected. We develop product candidates internally and through licensing collaborations, partnerships and joint ventures. Product candidates that are derived from relationships may be subject to disputes between the parties or may prove to be not as effective or as safe as we may have believed at the time of entering into such relationship. Also, we or others could identify safety, side effects or manufacturing problems with our products, including our devices, after they are on the market.
Our results may be affected by our ability to successfully market both new and existing products domestically and internationally, clinical and regulatory developments involving current and future products, sales growth of recently launched products, competition from other products including biosimilars, difficulties or delays in manufacturing our products and global economic conditions. In addition, sales of our products are affected by pricing pressure, political and public scrutiny and reimbursement policies imposed by third-party payers, including governments, private insurance plans and managed care providers and may be affected by regulatory, clinical and guideline developments and domestic and international trends toward managed care and healthcare cost containment. Furthermore, our research, testing, pricing, marketing and other operations are subject to extensive regulation by domestic and foreign government regulatory authorities. Our business may be impacted by government investigations, litigation and product liability claims. In addition, our business may be impacted by the adoption of new tax legislation or exposure to additional tax liabilities. If we fail to meet the compliance obligations in the corporate integrity agreement between us and the U.S. government, we could become subject to significant sanctions. Further, while we routinely obtain patents for our products and technology, the protection offered by our patents and patent applications may be challenged, invalidated or circumvented by our competitors, or we may fail to prevail in present and future intellectual property litigation. We perform a substantial amount of our commercial manufacturing activities at a few key facilities, including in
