Press Release Details

THOUSAND OAKS, Calif., Jan. 9, 2022 /PRNewswire/ -- Amgen (NASDAQ: AMGN) today announced that the European Commission (EC) has granted conditional marketing authorization for LUMYKRAS^® (sotorasib), a first-in-class KRAS^G12C 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 KRAS^G12C inhibitor 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 (grade ≥ 3) 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 KRAS G12C is one of the most prevalent driver mutations in NSCLC, with about 13-15% of European patients with non-squamous NSCLC having the KRAS G12C 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.

About LUMAKRAS^®/LUMYKRAS^® (sotorasib)
Amgen took on one of the toughest challenges of the last 40 years in cancer research by developing LUMAKRAS/LUMYKRAS, a KRAS^G12C inhibitor.⁵ LUMAKRAS/LUMYKRAS 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.⁶ 

Amgen is progressing the largest and broadest global KRAS^G12C 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, over 4,000 patients around the world have received LUMAKRAS/LUMYKRAS through the clinical development program and commercial use.

In May 2021, LUMAKRAS was the first KRAS^G12C inhibitor to receive regulatory approval anywhere in the world with its approval in the U.S., under accelerated approval.

Regulatory approvals have also been received in the United Arab Emirates (LUMAKRAS), Switzerland (LUMYKRAS), and under the FDA's Project Orbis in Canada (LUMAKRAS) and Great Britain (LUMYKRAS). Through Project Orbis, Amgen also has Marketing Authorization Applications (MAAs) for sotorasib in review in Australia, Brazil, Singapore and Israel. Additionally, Amgen has submitted MAAs in Japan, South Korea, Turkey, Taiwan, Colombia, Thailand, Mexico, Hong Kong, Saudi Arabia, Argentina, Kuwait and Qatar.

LUMAKRAS/LUMYKRAS is also being studied in multiple other solid tumors.⁷ 

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.⁸ 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.⁹

KRAS G12C is the most common KRAS mutation in NSCLC.¹⁰ About 13% of patients with non-squamous NSCLC harbor the KRAS G12C mutation.⁴ 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.¹¹

About CodeBreaK
The CodeBreaK clinical development program for Amgen's drug sotorasib is designed to study patients with an advanced solid tumor with the KRAS G12C mutation and address the longstanding unmet medical need for these cancers.

CodeBreaK 100, the Phase 1 and 2, first-in-human, open-label multicenter study, enrolled patients with KRAS G12C-mutant solid tumors.¹¹ 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.⁷ The Phase 2 trial in colorectal cancer (CRC) is fully enrolled and results have been submitted for publication.¹²

CodeBreaK 200, the global Phase 3 randomized active-controlled study comparing sotorasib to docetaxel in KRAS G12C-mutated NSCLC completed enrollment of 345 patients. Eligible patients had previously treated, locally-advanced and unresectable or metastatic KRAS G12C-mutated NSCLC. The primary endpoint is progression-free survival and key secondary endpoints include overall survival, objective response rate, and patient-reported outcomes.

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).

Important EU/EEA Product Information

LUMYKRAS^® (sotorasib) as monotherapy is indicated 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.

Important EU/EEA Safety information

This medicinal product is subject to additional monitoring. This will allow quick identification of new safety information. Healthcare professionals are asked to report any suspected adverse reactions.

Contraindications

LUMYKRAS is contraindicated in patients with a history of hypersensitivity to the active substance or to any of the excipients.

Special Warning and Precautions for Use

Hepatotoxicity:  Sotorasib can cause hepatotoxicity, which may lead to drug-induced liver injury (DILI) and hepatitis. Sotorasib has been associated with transient elevations of serum transaminases (ALT and AST). These elevations improved or resolved with dose modification or permanent discontinuation of treatment and did not result in any cases of liver failure or fatal cases in clinical studies. Among patients who experienced hepatotoxicity, 38% had hepatotoxicity leading to dose interruption or dose reduction.  Overall, 26% of patients with hepatotoxicity received concurrent corticosteroids. Cases of liver enzyme increase can be asymptomatic. Patients should be monitored for liver function (ALT, AST, and total bilirubin) prior to the start of LUMYKRAS, every 3 weeks for the first 3 months of treatment, then once a month or as clinically indicated, with more frequent testing in patients who develop transaminase and/or bilirubin elevations. Based on the severity of the laboratory abnormalities, treatment with LUMYKRAS must be stopped until recovered to ≤ grade 1 or to baseline grade, and the dose must either be modified or permanently discontinue treatment as recommended (see section 4.2).

Interstitial Lung Disease (ILD)/pneumonitis:  ILD/pneumonitis occurred in patients treated with LUMYKRAS with prior exposure to immunotherapy or radiotherapy (see section 4.8). Monitor patients for new or worsening pulmonary symptoms indicative of ILD/pneumonitis (e.g. dyspnoea, cough, fever). Immediately withhold LUMYKRAS in patients with suspected ILD/pneumonitis and permanently discontinue LUMYKRAS if no other potential causes of ILD/pneumonitis are identified (see section 4.2).

Lactose intolerance:  LUMYKRAS contains lactose. Patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose–galactose malabsorption should not take this medicinal product.

Adverse Reactions 

The most common adverse reactions were diarrhoea (34%), nausea (25%) and fatigue (21%). The most common severe adverse reactions were increased alanine aminotransferase (ALT) (5%), increased aspartate aminotransferase (AST) (4%), and diarrhoea (4%). The most common adverse reactions leading to permanent discontinuation of treatment were increased ALT (1%) and increased AST (1%) and drug-induced liver injury (1%). The most common adverse reactions leading to dose modification were increased ALT (6%), diarrhoea (6%), increased AST (6%), nausea (3%), increased blood alkaline phosphatase (3%) and vomiting (2%).

LUMAKRAS^® (sotorasib) U.S. Indication

LUMAKRAS 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).

Unless otherwise noted, Amgen is providing this information as of the date of this news release and does not undertake any obligation to update any forward-looking statements contained in this document as a result of new information, future events or otherwise.

No forward-looking statement can be guaranteed and actual results may differ materially from those we project. 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. We or others could identify safety, side effects or manufacturing problems with our products, including our devices, after they are on the market. 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. 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, 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.
