Amgen Data From Phase 3 CANDOR Study Combining KYPROLIS (carfilzomib) And DARZALEX (daratumumab) To Be Presented During Late-Breaking Session At American Society Of Hematology Annual Meeting

Press ReleaseTreatment With KYPROLIS, Dexamethasone and DARZALEX (KdD) Resulted in a Significant Progression-Free Survival (PFS) Benefit37% Reduction in the Risk of Progression or Death Compared to KYPROLIS and Dexamethasone (Kd) in Patients With Relapsed/Refractory Multiple MyelomaPatients Treated With KdD Achieved Deeper Responses Than Patients Treated With Kd Alone
THOUSAND OAKS, Calif.,?Dec. 10, 2019?/PRNewswire/ --?Amgen?(NASDAQ:AMGN) today announced additional results from the primary analysis of the Phase 3 CANDOR study evaluating KYPROLIS??(carfilzomib) in combination with dexamethasone and DARZALEX??(daratumumab) (KdD) compared to KYPROLIS and dexamethasone alone?(Kd) in patients with relapsed or refractory multiple myeloma. The data will be presented in a late-breaking abstract session at the 61st?American Society of Hematology?(ASH) Annual Meeting & Exposition. At a median follow up of 17 months, the study met its primary endpoint of progression-free survival (PFS), resulting in a 37% reduction in the risk of disease progression or death in patients receiving KdD (HR=0.63; 95% CI: 0.464, 0.854;?p=0.0014). Median PFS was not reached for the KdD arm versus 15.8 months for the Kd arm. "This primary analysis of the CANDOR study adds to the body of evidence supporting the combination of KYPROLIS and DARZALEX, two powerful targeted agents for multiple myeloma," said?David M. Reese, M.D., executive vice president of Research and Development at?Amgen. "KYPROLIS has demonstrated deep and sustained responses in treating patients with multiple myeloma that have relapsed. The CANDOR study now offers additional insight into the effectiveness of this combination as a potential new treatment option for relapsed myeloma patients." In addition to meeting the primary endpoint, the KdD combination demonstrated efficacy in key secondary endpoints, including overall response rate (ORR), minimal residual disease (MRD) negative-complete response at 12 months and overall survival (OS). The ORR was 84.3% versus 74.7% (p=0.0040), and the rate of complete response or better was 28.5% versus 10.4% for the KdD and Kd arms, respectively. The analysis found the MRD-negative complete response rate at 12 months was 12.5% for KdD versus 1.3% for Kd (p<0.0001), a nearly 10-times higher response rate versus Kd-treated patients. The median OS was not reached in either group (HR=0.75; 95% CI: 0.49, 1.13;?p=0.08). "With the increasing use of frontline lenalidomide based therapies, there is an emerging need for lenalidomide-sparing regimens at relapse," said?Saad Usmani, M.D., chief of the Plasma Cell Disorders Division and the director of Clinical Research in Hematologic Malignancies,?Atrium Health's?Levine Cancer Institute?(LCI). "The CANDOR trial demonstrates the potential efficacy of a lenalidomide-sparing regimen that combines two effective targeted agents and provides deep and durable responses upon relapse." The safety of KdD was consistent with the known safety profiles of the individual agents. The most frequently reported (= 20% of subjects in either treatment arm [KdD, Kd]) treatment emergent adverse events included thrombocytopenia, anemia, diarrhea, hypertension upper respiratory tract infection, fatigue, and dyspnea. The incidence of treatment emergent grade 3 or higher, serious, and fatal adverse events was higher in the KdD arm compared to the Kd arm. The rate of treatment discontinuation due to AEs was similar in both arms. Additional efficacy endpoints and key subgroup analyses will be presented at future meetings. About CANDOR CANDOR, a randomized, open-label Phase 3 study of KYPROLIS, dexamethasone and DARZALEX (KdD) compared to KYPROLIS and dexamethasone (Kd), 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 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.

About Multiple Myeloma Multiple myeloma is an incurable blood cancer, characterized by a recurring pattern of remission and relapse.1?It is a rare and life-threatening disease that accounts for approximately one percent of all cancers.2,3?Worldwide, approximately 160,000 people are diagnosed with multiple myeloma each year, and 106,000 patient deaths are reported on an annual basis.2 About KYPROLIS??(carfilzomib) Proteasomes play an important role in cell function and growth by breaking down proteins that are damaged or no longer needed.4?KYPROLIS has been shown to block proteasomes, leading to an excessive build-up of proteins within cells.5?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.4,5 Since its first approval in 2012, approximately 130,000 patients worldwide have received KYPROLIS. KYPROLIS is approved in the U.S. for the following:
  • In combination with dexamethasone or with lenalidomide plus dexamethasone for the treatment of patients with relapsed or refractory multiple myeloma who have received one to three lines of therapy
  • 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,?Kuwait,?Lebanon,?Macao,?Malaysia,?Mexico,?Morocco,?New Zealand,?Oman,?Peru,?Philippines,?Qatar,?Russia,?Saudi Arabia,?Singapore, S. Korea,?Switzerland,?Taiwan,?Thailand,?Turkey?and?United Arab Emirates. Important U.S. KYPROLIS??(carfilzomib) Safety Information Cardiac Toxicities
  • New onset or worsening of pre-existing cardiac failure (e.g., congestive heart failure, pulmonary edema, decreased ejection fraction), restrictive cardiomyopathy, myocardial ischemia, and myocardial infarction including fatalities have occurred following administration of KYPROLIS. Some events occurred in patients with normal baseline ventricular function. Death due to cardiac arrest has occurred within one day of administration.
  • Monitor patients for signs or symptoms of cardiac failure or ischemia. Evaluate promptly if cardiac toxicity is suspected. Withhold KYPROLIS for Grade 3 or 4 cardiac adverse events until recovery, and consider whether to restart at 1 dose level reduction based on a benefit/risk assessment.
  • While adequate hydration is required prior to each dose in Cycle 1, monitor all patients for evidence of volume overload, especially patients at risk for cardiac failure. Adjust total fluid intake as clinically appropriate.
  • For patients = 75 years, the risk of cardiac failure is increased. Patients with New York Heart Association Class III and IV heart failure, recent myocardial infarction, conduction abnormalities, angina, or arrhythmias may be at greater risk for cardiac complications and should have a comprehensive medical assessment prior to starting treatment with KYPROLIS and remain under close follow-up with fluid management.
Acute Renal Failure
  • Cases of acute renal failure, including some fatal renal failure events, and renal insufficiency adverse events (including renal failure) have occurred. Acute renal failure was reported more frequently in patients with advanced relapsed and refractory multiple myeloma who received KYPROLIS monotherapy. Monitor renal function with regular measurement of the serum creatinine and/or estimated creatinine clearance. Reduce or withhold dose as appropriate.
Tumor Lysis Syndrome
  • Cases of Tumor Lysis Syndrome (TLS), including fatal outcomes, have occurred. Patients with a high tumor burden should be considered at greater risk for TLS. Adequate hydration is required prior to each dose in Cycle 1, and in subsequent cycles as needed. Consider uric acid lowering drugs in patients at risk for TLS. Monitor for evidence of TLS during treatment and manage promptly, and withhold until resolved.
Pulmonary Toxicity
  • Acute Respiratory Distress Syndrome (ARDS), acute respiratory failure, and acute diffuse infiltrative pulmonary disease such as pneumonitis and interstitial lung disease have occurred. Some events have been fatal. In the event of drug-induced pulmonary toxicity, discontinue KYPROLIS.
Pulmonary Hypertension
  • Pulmonary arterial hypertension (PAH) was reported. Evaluate with cardiac imaging and/or other tests as indicated. Withhold KYPROLIS for PAH until resolved or returned to baseline and consider whether to restart based on a benefit/risk assessment.
Dyspnea
  • Dyspnea was reported in patients treated with KYPROLIS. Evaluate dyspnea to exclude cardiopulmonary conditions including cardiac failure and pulmonary syndromes. Stop KYPROLIS for Grade 3 or 4 dyspnea until resolved or returned to baseline. Consider whether to restart based on a benefit/risk assessment.
Hypertension
  • Hypertension, including hypertensive crisis and hypertensive emergency, has been observed, some fatal. Control hypertension prior to starting KYPROLIS. Monitor blood pressure regularly in all patients. If hypertension cannot be adequately controlled, withhold KYPROLIS and evaluate. Consider whether to restart based on a benefit/risk assessment.
Venous Thrombosis
  • Venous thromboembolic events (including deep venous thrombosis and pulmonary embolism) have been observed. Thromboprophylaxis is recommended for patients being treated with the combination of KYPROLIS with dexamethasone or with lenalidomide plus dexamethasone. The thromboprophylaxis regimen should be based on an assessment of the patient's underlying risks.
  • Patients using hormonal contraception associated with a risk of thrombosis should consider an alternative method of effective contraception during treatment.
Infusion Reactions
  • Infusion reactions, including life-threatening reactions, have occurred. Signs and symptoms include fever, chills, arthralgia, myalgia, facial flushing, facial edema, laryngeal edema, vomiting, weakness, shortness of breath, hypotension, syncope, chest tightness, or angina. These reactions can occur immediately following or up to 24 hours after administration. Pre-medicate with dexamethasone to reduce the incidence and severity of infusion reactions. Inform patients of the risk and of symptoms and seek immediate medical attention if they occur.
Hemorrhage
  • Fatal or serious cases of hemorrhage have been reported. Hemorrhagic events have included gastrointestinal, pulmonary, and intracranial hemorrhage and epistaxis. Promptly evaluate signs and symptoms of blood loss. Reduce or withhold dose as appropriate.
Thrombocytopenia
  • KYPROLIS causes thrombocytopenia with recovery to baseline platelet count usually by the start of the next cycle. Monitor platelet counts frequently during treatment. Reduce or withhold dose as appropriate.
Hepatic Toxicity and Hepatic Failure
  • Cases of hepatic failure, including fatal cases, have occurred. KYPROLIS can cause increased serum transaminases. Monitor liver enzymes regularly regardless of baseline values. Reduce or withhold dose as appropriate.
Thrombotic Microangiopathy
  • Cases of thrombotic microangiopathy, including thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS), including fatal outcome have occurred. Monitor for signs and symptoms of TTP/HUS. Discontinue if diagnosis is suspected. If the diagnosis of TTP/HUS is excluded, KYPROLIS may be restarted. The safety of reinitiating KYPROLIS is not known.
Posterior Reversible Encephalopathy Syndrome (PRES)
  • Cases of PRES have occurred in patients receiving KYPROLIS. If PRES is suspected, discontinue and evaluate with appropriate imaging. The safety of reinitiating KYPROLIS is not known.
Increased Fatal and Serious Toxicities in Combination with Melphalan and Prednisone in Newly Diagnosed Transplant-ineligible?Patients
  • In a clinical trial of transplant-ineligible patients with newly diagnosed multiple myeloma comparing KYPROLIS, melphalan, and prednisone (KMP) vs bortezomib, melphalan, and prednisone (VMP), a higher incidence of serious and fatal adverse events was observed in patients in the KMP arm. KMP is not indicated for transplant-ineligible patients with newly diagnosed multiple myeloma.
Embryo-fetal Toxicity
  • KYPROLIS can cause fetal harm when administered to a pregnant woman.
  • Females of reproductive potential should be advised to avoid becoming pregnant while being treated with KYPROLIS and for 6 months following the final dose. Males of reproductive potential should be advised to avoid fathering a child while being treated with KYPROLIS and for 3 months following the final dose. If this drug is used during pregnancy, or if pregnancy occurs while taking this drug, the patient should be apprised of the potential hazard to the fetus.
ADVERSE REACTIONS
  • The most common adverse reactions in the combination therapy trials: anemia, neutropenia, diarrhea, dyspnea, fatigue, thrombocytopenia, pyrexia, insomnia, muscle spasm, cough, upper respiratory tract infection, hypokalemia.
  • The most common adverse reactions in monotherapy trials: anemia, fatigue, thrombocytopenia, nausea, pyrexia, dyspnea, diarrhea, headache, cough, edema peripheral.

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. 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 or products, and to integrate the operations of companies or in support of products 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.
