THOUSAND OAKS, Calif., Aug. 20, 2020 /PRNewswire/ — Amgen (NASDAQ:AMGN) today announced the U.S. Food and Drug Administration (FDA) has approved the expansion of the Kyprolis (carfilzomib) U.S. prescribing information to include its use in combination with Darzalex (daratumumab) plus dexamethasone (DKd) in two dosing regimens — once weekly and twice weekly — for the treatment of patients with relapsed or refractory multiple myeloma (R/R MM) who have received one to three previous lines of therapy.

“This expanded approval for Kyprolis demonstrates a leap forward in the treatment paradigm for this complex disease by combining two potent agents in their respective drug classes indicated for patients with relapsed or refractory multiple myeloma,” said David M. Reese, M.D., executive vice president of Research and Development at Amgen.

Multiple myeloma is a blood cancer characterized by patterns of remission and relapse. Patient outcomes worsen with each relapse.1 With the increasing use of frontline immunomodulatory drug based (IMiD) therapies through progression, the number of patients treated with these agents who will progress is likely to increase with time. This creates an emerging need for efficacious lMiD-free regimens upon relapse.2 

“Now, we can provide healthcare professionals and patients with an efficacious regimen with two dosing options at a critical time in a patient’s treatment journey: first relapse,” Reese continued.

“The DKd regimen provides an important potent triplet option in the setting of relapse following IMiD combination frontline therapy,” said Brian G.M. Durie, M.D., chairman, International Myeloma Foundation.

The Phase 3 CANDOR trial was the first Phase 3 randomized trial to compare DKd versus Kyprolis and dexamethasone (Kd) alone in R/R MM patients. The study met its primary endpoint and resulted in a 37% reduction in the risk of disease progression or death in patients receiving DKd (HR=0.63; 95% CI: 0.464, 0.854; p-value [1-sided]=0.0014) compared to Kd alone.

“Despite ongoing advances in the treatment of multiple myeloma, the disease remains incurable and is especially challenging for patients who relapse or become refractory to established therapies,” said Saad Z. Usmani, M.D., director of clinical research in hematologic malignancies; director of plasma cell disorders; clinical professor of medicine, Atrium Health’s Levine Cancer Institute. “As a clinician, having the DKd regimen as an option means we can now combine two efficacious, targeted agents in a new, immunomodulatory drug-free triplet regimen that has demonstrated deep and durable responses for patients upon relapse.”

In CANDOR, the safety of DKd was generally consistent with the known safety profiles of the individual agents. The most frequently reported (≥ 20% of subjects in either treatment arm [DKd, Kd]) treatment-emergent adverse events (AEs) included infusion-related reactions, anemia, diarrhea, fatigue, hypertension, pyrexia, upper respiratory tract infection, thrombocytopenia, neutropenia, lymphopenia, cough, dyspnea, and insomnia, headache and back pain. The incidence of treatment-emergent Grade 3 or higher, serious and fatal AEs was higher in the DKd arm compared to the Kd arm. The most common reason for fatal treatment-emergent AEs in both arms was infection. The rate of treatment discontinuation due to AEs was similar in both arms.

The expansion of Kyprolis’s prescribing information to include once-weekly dosing of Kyprolis within the DKd regimen was supported by the open-label, multi-cohort Phase 1b EQUULEUS trial, in which the safety and efficacy of DKd was assessed among R/R MM patients using a once-weekly dosing regimen for Kyprolis.

About CANDOR
CANDOR, a randomized, open-label Phase 3 study of Kyprolis, Darzalex and dexamethasone (DKd) compared to Kyprolis and dexamethasone (Kd), has evaluated 466 relapsed or refractory multiple myeloma patients who have received one to three prior therapies. Patients were treated until disease progression. The primary endpoint was progression-free survival (PFS), and the key secondary endpoints were overall response rate, minimal residual disease and overall survival. PFS was defined as time from randomization until disease progression or death from any cause.

In the first arm, patients received Kyprolis twice weekly at 56 mg/m2 and dexamethasone in combination with Darzalex. In the second arm (control), patients received Kyprolis twice weekly at 56 mg/m2 and dexamethasone.

CANDOR was initiated as part of a collaboration with Janssen, and under the terms of the agreement, Janssen co-funded the study. For more information about this trial, please visit www.clinicaltrials.gov under trial identification number NCT03158688.

About EQUULEUS
EQUULEUS was an open label, Phase 1b, multi-cohort trial which evaluated the combination of Kyprolis with intravenous Darzalex and dexamethasone in 85 patients with relapsed or refractory multiple myeloma who had received one to three prior lines of therapy. 

Kyprolis was evaluated at a starting dose of 20 mg/m2, which was increased to 70 mg/m2 on Cycle 1, Day 8 and onward.

The most frequently reported all-grade, treatment-emergent AEs (occurring in 20% or more of patients) were thrombocytopenia, respiratory tract infection, anemia, nausea, fatigue, vomiting, diarrhea, pyrexia, neutropenia, lymphopenia, infusion related reactions, dyspnea, cough, insomnia, hypertension, headache and back pain.

At a median follow-up of 16.6 months, the overall response rate was 81% in all treated patients: 21% achieved a stringent complete response, 14% a complete response, 33% a very good partial response and 13% a partial response.

About Multiple Myeloma
Multiple myeloma is an incurable blood cancer, characterized by a recurring pattern of remission and relapse.3 It is a rare and life-threatening disease that accounts for approximately one percent of all cancers.4,5 Worldwide, approximately 160,000 people are diagnosed with multiple myeloma each year, and 106,000 patient deaths are reported on an annual basis.4

About Kyprolis (carfilzomib)

Proteasomes play an important role in cell function and growth by breaking down proteins that are damaged or no longer needed.6 Kyprolis has been shown to block proteasomes, leading to an excessive build-up of proteins within cells.7 In some cells, Kyprolis can cause cell death, especially in myeloma cells because they are more likely to contain a higher amount of abnormal proteins.6,7

Since its first approval in 2012, approximately 150,000 patients worldwide have received Kyprolis.8 Kyprolis is approved in the U.S. for the following:

  • for the treatment of patients with relapsed or refractory multiple myeloma who have received one to three lines of therapy in combination with

    • Lenalidomide and dexamethasone; or
    • Dexamethasone; or
    • Daratumumab and dexamethasone.

  • as a single agent for the treatment of patients with relapsed or refractory multiple myeloma who have received one or more lines of therapy.
    Kyprolis is also approved in Algeria, Argentina, Australia, Bahrain, Belarus, Brazil, Canada, Chile, Colombia, Ecuador, Egypt, European Union, Hong Kong, India, Israel, Japan, Jordan, Kazakhstan, Kuwait, Lebanon, Macao, Malaysia, Mexico, Morocco, New Zealand, Oman, Peru, Philippines, Qatar, Russia, Saudi Arabia, Serbia, Singapore, S. Africa, S. Korea, Switzerland, Taiwan, Thailand, Turkey and United Arab Emirates.

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 Adaptive Biotechnologies (including statements regarding such collaboration’s ability to discover and develop fully-human neutralizing antibodies targeting SARS-CoV-2 to potentially prevent or treat COVID-19), BeiGene, Ltd., or the Otezla® (apremilast) acquisition, including anticipated Otezla sales growth and the timing of non-GAAP EPS accretion, 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 such as the ongoing COVID-19 pandemic on our business, outcomes, progress, or effects relating to studies of Otezla as a potential treatment for COVID-19, 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 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. 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. 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.
