THOUSAND OAKS, Calif., Oct. 16, 2023 /PRNewswire/ -- Amgen (NASDAQ:AMGN) today announced the presentation of new data across its broad oncology portfolio and pipeline at the European Society for Medical Oncology (ESMO) Congress 2023, taking place from October 20-24 in Madrid. Results from Amgen-sponsored and collaborative studies, including two late-breaking oral presentations, will feature data in a range of tough-to-treat cancers.
"Our data at ESMO demonstrate the rapid progress we are making in advancing a portfolio with first-in-class therapies, including metastatic KRAS G12C mutated colorectal cancer and small cell lung cancer," said David M. Reese, M.D., executive vice president of Research and Development at Amgen. "These findings illustrate how we are attacking cancer from many different angles to deliver new approaches poised to alter the natural history of disease across many cancers."
Amgen will present data from two late-breaking abstracts at ESMO:
Interim results from a Phase 1 study of AMG 509 (xaluritamig) will be presented during a Proffered Paper Oral Session (Abstract #1765O), demonstrating that the novel bispecific STEAP1 x CD3 XmAb® 2+1 T-cell engager had a positive benefit/risk profile with robust anti-tumor activity in heavily pretreated patients with mCRPC (N=97). Overall, of the 67 RECIST-evaluable patients, 16 (24%) had confirmed partial responses (PR) and 32 (48%) had stable disease (SD), demonstrating encouraging preliminary efficacy. At higher dosing levels (n=37), 15 patients (41%) had confirmed PR and 14 (38%) with SD. The most common treatment-related adverse events were cytokine release syndrome (CRS; 72%; primarily low grade), fatigue (45%), myalgia (34%) and pyrexia (32%).
These results further justify exploration of this modality as a potential therapy for prostate cancer. Dose expansion and optimization are currently ongoing.

About LUMAKRAS®/LUMYKRAS® (sotorasib)
LUMAKRAS received accelerated approval from the U.S. Food and Drug Administration on May 28, 2021. The Supplemental New Drug Application (sNDA) for full approval of LUMAKRAS was accepted by the FDA for standard review and a Prescription Drug User Fee Act (PDUFA) target action date of December 24, 2023, has been set.
About Advanced Colorectal Cancer and the KRAS G12C Mutation
Colorectal cancer (CRC) is the second leading cause of cancer deaths worldwide, comprising 10% of all cancer diagnoses.1 It is also the third most commonly diagnosed cancer globally.2
Patients with previously treated metastatic CRC need more effective treatment options. For patients in the third-line setting, standard therapies yield median progression-free survival (PFS) times of about two months, and patients' response rates are less than 10%.3
KRAS mutations are among the most common genetic alterations in colorectal cancers, with the KRAS G12C mutation present in approximately 3-5% of colorectal cancers.4,5,6
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.7 Eligible patients must have received at least 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 non-small cell lung cancer (NSCLC) enrolled 126 patients, 124 of whom had centrally evaluable lesions by RECIST at baseline.8 The Phase 2 trial in colorectal cancer (CRC) enrolled 62 patients and results have been published.9
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.10
CodeBreaK 300, the global Phase 3 randomized active-controlled study comparing sotorasib in combination with panitumumab to investigator's choice (trifluridine and tipiracil, or regorafenib) in chemorefractory KRAS G12C-mutated mCRC, has completed enrollment of 160 patients. Eligible patients had KRAS G12C-mutated mCRC, received at least one prior line of therapy, and have received and progressed on or after fluoropyrimidine, irinotecan, and oxaliplatin. The primary endpoint is progression-free survival, and key secondary endpoints include overall survival (OS) and objective response rate (ORR).11
Amgen also has several Phase 1b studies investigating sotorasib monotherapy and sotorasib combination therapy across various advanced solid tumors (CodeBreaK 101) open for enrollment.12 A Phase 2 randomized study evaluating sotorasib in patients with stage IV KRAS G12C-mutated NSCLC in need of first-line treatment is ongoing (CodeBreaK 201).13 Amgen has also initiated a Phase 3 study of LUMAKRAS plus carboplatin and pemetrexed in first-line KRAS G12C-mutant and negative for programmed cell death PD-L1 advanced NSCLC (CodeBreaK 202), with enrollment expected to start before the end of 2023.
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).

About Vectibix® (panitumumab)
Vectibix is the first and only fully human monoclonal anti-EGFR antibody approved by the FDA for the treatment of mCRC. Vectibix was approved in the U.S. in September 2006 as a monotherapy for the treatment of patients with EGFR-expressing mCRC after disease progression after prior treatment with fluoropyrimidine-, oxaliplatin-, and irinotecan-containing chemotherapy.
In May 2014, the FDA approved Vectibix for use in combination with FOLFOX as first-line treatment in patients with wild-type KRAS (exon 2) mCRC. With this approval, Vectibix became the first-and-only biologic therapy indicated for use with FOLFOX, one of the most commonly used chemotherapy regimens, in the first-line treatment of mCRC for patients with wild-type KRAS mCRC.
In June 2017, the FDA approved a refined indication for Vectibix for use in patients with wild-type RAS (defined as wild-type in both KRAS and NRAS as determined by an FDA-approved test for this use) mCRC.
INDICATION AND LIMITATION OF USE
Vectibix® is indicated for the treatment of patients with wild-type RAS (defined as wild-type in both KRAS and NRAS as determined by an FDA-approved test for this use) metastatic colorectal cancer (mCRC): as first-line therapy in combination with FOLFOX, and as monotherapy following disease progression after prior treatment with fluoropyrimidine-, oxaliplatin-, and irinotecan-containing chemotherapy.
Limitation of Use: Vectibix® is not indicated for the treatment of patients with RAS mutant mCRC or for whom RAS mutation status is unknown.
IMPORTANT SAFETY INFORMATION
BOXED WARNING: DERMATOLOGIC TOXICITY
Dermatologic Toxicity: Dermatologic toxicities occurred in 90% of patients and were severe (NCI-CTC grade 3 and higher) in 15% of patients receiving Vectibix monotherapy [see Dosage and Administration (2.3), Warnings and Precautions (5.1), and Adverse Reactions (6.1)].

About Tarlatamab
Tarlatamab is an investigational, targeted immunotherapy engineered by Amgen researchers that brings a patient's own T cells in close proximity to SCLC cells by binding both CD3 on T cells and DLL3 on SCLC cells. This results in the formation of an immunological synapse with lysis of the cancer cell.14,15 DLL3 represents an exciting therapeutic target for patients with SCLC, as approximately 85% to 94% of patients have expression of DLL3 on the cell surface of SCLC cells, with minimal expression in normal cells.16,17,18
Amgen is currently investigating tarlatamab in multiple trials, including DeLLphi-304, a Phase 3 study comparing tarlatamab versus standard of care chemotherapy in second-line treatment of SCLC that is enrolling patients. Amgen has plans to initiate two additional Phase 3 studies of tarlatamab in earlier settings of SCLC.

Amgen Forward-Looking Statements
This news release contains forward-looking statements that are based on the current expectations and beliefs of Amgen. All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements, including any statements on the outcome, benefits and synergies of collaborations, or potential collaborations, with any other company (including BeiGene, Ltd. or Kyowa-Kirin Co., Ltd.), the performance of Otezla® (apremilast) (including anticipated Otezla sales growth and the timing of non-GAAP EPS accretion), the Teneobio, Inc. acquisition, the ChemoCentryx, Inc. acquisition, or the Horizon Therapeutics plc acquisition (including the prospective performance and outlook of Horizon's business, performance and opportunities and any potential strategic benefits, synergies or opportunities expected as a result of such acquisition), as well as estimates of revenues, operating margins, capital expenditures, cash, other financial metrics, expected legal, arbitration, political, regulatory or clinical results or practices, customer and prescriber patterns or practices, reimbursement activities and outcomes, effects of pandemics or other widespread health problems on our business, outcomes, progress, and other such estimates and results. Forward-looking statements involve significant risks and uncertainties, including those discussed below and more fully described in the Securities and Exchange Commission reports filed by Amgen, including our most recent annual report on Form 10-K and any subsequent periodic reports on Form 10-Q and current reports on Form 8-K. Unless otherwise noted, Amgen is providing this information as of the date of 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. 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. There can be no guarantee that we will be able to realize any of the strategic benefits, synergies or opportunities arising from the Horizon acquisition, and such benefits, synergies or opportunities may take longer to realize than expected. We may not be able to successfully integrate Horizon, and such acquisition or integration may take longer, be more difficult or cost more than expected. A breakdown, cyberattack or information security breach of our information technology systems 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. Our business and operations may be negatively affected by the failure, or perceived failure, of achieving our environmental, social and governance objectives. The effects of global climate change and related natural disasters could negatively affect our business and operations. 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.
