Amgen Announces New LUMAKRAS™ (sotorasib) Combination Data From Phase 1b CodeBreaK 101 Study In Patients With KRAS G12C-mutated Cancers At AACR-NCI-EORTC 2021
THOUSAND OAKS, Calif., Oct. 7, 2021 /PRNewswire/ -- Amgen (NASDAQ: AMGN) today announced new combination study results from the Phase 1b CodeBreaK 101 study, a comprehensive global master protocol trial evaluating the safety and efficacy of LUMAKRAS™ (sotorasib), the first and only approved KRASG12C inhibitor, in more than 10 different investigational combination regimens for the treatment of patients with KRAS G12C-mutated cancers. Results from two arms of the study — LUMAKRAS with afatinib, a pan-ErbB tyrosine kinase inhibitor, and LUMAKRAS with trametinib, a mitogen-activated protein kinase inhibitor (MEKi) — will be presented at the plenary session titled 'Drugging Difficult Targets' during the AACR-NCI-EORTC 2021 Virtual International Conference on Molecular Targets and Cancer Therapeutics on Saturday, Oct. 9, 2021.
"A critical component of cancer drug development is to interrogate multiple pathways to understand whether different combinations can meaningfully advance cancer care. For this reason, Amgen has undertaken the broadest and most comprehensive global clinical development program for patients with the KRAS G12C mutation, exploring multiple combinations that will allow us to understand where we can best serve patients," said David M. Reese, M.D., executive vice president of Research and Development at Amgen. "Consistent with our master protocol clinical trial design, which allows us to rapidly add, expand or remove cohorts to quickly understand what combinations work best for patients, Amgen will take these afatinib and trametinib results into account as we prioritize which combinations to move forward within our comprehensive LUMAKRAS development program. We look forward to presenting additional data, including PD-1 and SHP2 combination datasets, in the coming months."
LUMAKRAS in Combination with Afatinib (Abstract LBA6581)
The most common treatment-related adverse events (TRAEs) for this study were diarrhea, nausea, and vomiting. TRAEs of grade 3 occurred in 30% of patients in both dose groups with diarrhea being the most common.
LUMAKRAS in Combination with Trametinib (Abstract LBA6580)
In patients with CRC who were KRASG12C inhibitor naïve, 9% achieved partial response (1 of 11), and 82% achieved disease control (9 of 11). In patients who were previously treated with a KRASG12C inhibitor, 14% achieved partial response (1 of 7), and 86% achieved disease control (6 of 7).
In patients with NSCLC who were KRASG12C inhibitor naïve, 20% achieved partial response (3 of 15) and 87% achieved disease control (13 of 15). In patients who were previously treated with a KRASG12C inhibitor, 67% achieved disease control (2 of 3).
The most common TRAEs for this study were diarrhea, rash, dermatitis acneiform, nausea and vomiting. No new safety concerns were identified.
About LUMAKRASTM (sotorasib)
In May 2021, LUMAKRAS was the first KRASG12C inhibitor to receive regulatory approval anywhere in the world with its approval in the U.S., under accelerated approval. LUMAKRAS is also approved in the United Arab Emirates, and in Canada and Great Britain under Project Orbis.
Amgen is progressing the largest and broadest global KRASG12C inhibitor development program with unparalleled speed and exploring more than 10 sotorasib combination regimens, including triplets, with clinical trial sites spanning five continents. To date, LUMAKRAS has treated over 3,000 patients around the world through the clinical development program and commercial use.
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 Marketing Authorization Applications (MAAs) for sotorasib in review in Australia and Brazil. Additionally, Amgen has submitted an MAA in the European Union, Japan, Switzerland, South Korea, Singapore, Israel, Turkey, Taiwan, Colombia, Thailand, Mexico and Hong Kong.
LUMAKRAS is also being studied in multiple other solid tumors.1
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 results have been submitted for publication.
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. A Phase 2 randomized study will evaluate sotorasib in patients with stage IV KRAS G12C-mutated NSCLC in need of first-line treatment (CodeBreaK 201).

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 Puerto Rico, and also depend on third parties for a portion of our manufacturing activities, and limits on supply may constrain sales of certain of our current products and product candidate development. An outbreak of disease or similar public health threat, such as COVID-19, and the public and governmental effort to mitigate against the spread of such disease, could have a significant adverse effect on the supply of materials for our manufacturing activities, the distribution of our products, the commercialization of our product candidates, and our clinical trial operations, and any such events may have a material adverse effect on our product development, product sales, business and results of operations. We rely on collaborations with third parties for the development of some of our product candidates and for the commercialization and sales of some of our commercial products. In addition, we compete with other companies with respect to many of our marketed products as well as for the discovery and development of new products. Further, some raw materials, medical devices and component parts for our products are supplied by sole third-party suppliers. Certain of our distributors, customers and payers have substantial purchasing leverage in their dealings with us. The discovery of significant problems with a product similar to one of our products that implicate an entire class of products could have a material adverse effect on sales of the affected products and on our business and results of operations. Our efforts to collaborate with or acquire other companies, products or technology, and to integrate the operations of companies or to support the products or technology we have acquired, may not be successful. A breakdown, cyberattack or information security breach could compromise the confidentiality, integrity and availability of our systems and our data. Our stock price is volatile and may be affected by a number of events. Global economic conditions may magnify certain risks that affect our business. Our business performance could affect or limit the ability of our Board of Directors to declare a dividend or our ability to pay a dividend or repurchase our common stock. We may not be able to access the capital and credit markets on terms that are favorable to us, or at all.
The scientific information discussed in this news release related to our product candidates is preliminary and investigative. Such product candidates are not approved by the U.S. Food and Drug Administration, and no conclusions can or should be drawn regarding the safety or effectiveness of the product candidates. Further, any scientific information discussed in this news release relating to new indications for our products is preliminary and investigative and is not part of the labeling approved by the U.S. Food and Drug Administration for the products. The products are not approved for the investigational use(s) discussed in this news release, and no conclusions can or should be drawn regarding the safety or effectiveness of the products for these uses.
