Data submitted to regulatory authorities showed that KYPROLIS, administered at the 56 mg/m2 dose as a 30-minute infusion twice weekly with dexamethasone (Kd56), reduced the risk of death by 21 percent over Velcade® (bortezomib) and dexamethasone (Vd), resulting in a 7.6 month OS benefit (median OS 47.6 months for Kd56 versus 40.0 months for Vd, HR=0.79; p=0.01). The OS benefit was consistent regardless of prior bortezomib therapy (HR 0.75 for no prior Velcade; HR 0.84 for prior Velcade). These results were presented earlier this year at the 16th
"KYPROLIS is the first-and-only multiple myeloma therapy to demonstrate superior overall survival in a head-to-head comparison with a current standard of care, extending survival by 7.6 months over Velcade," said
Since its approval in 2012, KYPROLIS has been prescribed to more than 50,000 patients worldwide. The KYPROLIS clinical program continues to focus on providing solutions for physicians and patients in treating this frequently relapsing and difficult-to-treat cancer. KYPROLIS is available for patients whose myeloma has relapsed or become resistant to another treatment and continues to be studied in a range of combinations and patient populations.
Adverse events observed in this updated analysis were consistent with those previously reported for ENDEAVOR. The most common adverse events (greater than or equal to 20 percent) in the KYPROLIS arm were anemia, diarrhea, pyrexia, dyspnea, fatigue, hypertension, cough, insomnia, upper respiratory tract infection, peripheral edema, nausea, bronchitis, asthenia, back pain, thrombocytopenia and headache.
About ENDEAVOR
The randomized ENDEAVOR (RandomizEd, OpeN Label, Phase 3 Study of Carfilzomib Plus DExamethAsone Vs Bortezomib Plus DexamethasOne in Patients With Relapsed Multiple Myeloma) trial of 929 patients evaluated Kd56 versus Vd in patients whose multiple myeloma has relapsed after at least one, but not more than three prior therapeutic regimens. The primary endpoint of the trial was progression-free survival, defined as the time from treatment initiation to disease progression or death. The primary analysis was published in The Lancet Oncology and is described in the Prescribing Information.
Patients received treatment until progression with KYPROLIS as a 30-minute infusion on days 1, 2, 8, 9, 15 and 16 of 28 day treatment cycles, along with low-dose dexamethasone (20 mg). For cycle one only, KYPROLIS was administered at 20 mg/m2 on days 1 and 2, and if tolerated was escalated to 56 mg/m2 from day 8 cycle one onwards. Patients who received bortezomib (1.3 mg/m2) with low-dose dexamethasone (20 mg) were treated with bortezomib administered subcutaneously or intravenously at the discretion of the investigator and in accordance with regional regulatory approval of bortezomib. Eighty-two percent of the patients in the control arm received bortezomib subcutaneously. This study was conducted at 235 sites worldwide.

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 very aggressive disease that accounts for approximately one percent of all cancers.2,3 In the U.S., there are nearly 95,000 people living with, or in remission from, multiple myeloma.4 Approximately 30,330 Americans are diagnosed with multiple myeloma each year and 12,650 patient deaths are reported on an annual basis.4 In Europe, approximately 39,000 patients are diagnosed with multiple myeloma each year and 24,000 patient deaths are reported on an annual basis.5
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.6 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
KYPROLIS is approved in the U.S. for the following:

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 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 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 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 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. We or others could identify safety, side effects or manufacturing problems with our products 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 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. 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 acquire other companies or products and to integrate the operations of companies we have acquired may not be successful. We may not be able to access the capital and credit markets on terms that are favorable to us, or at all. We are increasingly dependent on information technology systems, infrastructure and data security. 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.
The 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
