THOUSAND OAKS, Calif., Aug. 13 /PRNewswire-FirstCall/ -- Amgen Inc. (Nasdaq: AMGN) issued the following statement on the outcome of today's meeting with the U.S. Food and Drug Administration (FDA) Advisory Committee for Reproductive Health Drugs (ACRHD) to review the potential use of Prolia(TM) (denosumab) for the prevention and treatment of postmenopausal osteoporosis and the prevention and treatment of bone loss in patients undergoing hormone ablation for either prostate cancer or breast cancer.
After reviewing safety and efficacy data from 30 clinical studies involving more than 12,000 patients, the Committee recommended approval of Prolia for the treatment of postmenopausal osteoporosis and for the treatment of bone loss in patients undergoing hormone ablation for prostate cancer. The Committee recommended against approval of Prolia to treat or prevent bone loss in women with breast cancer undergoing hormone ablation until additional data are available.
The Committee also recommended against approval of Prolia to prevent bone loss in low-risk patients in all three populations.
Finally, the panel recommended that Prolia have a Risk Evaluation and Mitigation Strategy (REMS), which could include a medication guide and a healthcare provider communications plan.
The FDA often seeks the advice of an advisory committee such as the ACRHD when evaluating a potential new treatment but is not required to follow its recommendation.
Postmenopausal osteoporosis is a major public health concern resulting in fractures that cause significant clinical morbidity, mortality, and healthcare burden, and there remains a need for additional treatment alternatives. Similarly, bone loss due to hormone ablation in the setting of cancer therapy results in significant morbidity, and has no currently approved treatments.
Patient safety is Amgen's top priority. Amgen proposed a comprehensive post-marketing surveillance program, including extensions of studies in the osteoporosis and oncology settings in which more than 5,000 patients will be treated with Prolia for up to 10 years, as well as ongoing studies in the advanced cancer setting. In addition, the Company proposed an observational study using healthcare databases that will involve approximately 380,000 women with postmenopausal osteoporosis for up to 5 years.
"Amgen looks forward to collaborating with the FDA to arrive at the best possible approach to make Prolia available to appropriate patients," said Roger M. Perlmutter, M.D., Ph.D., executive vice president of Research and Development at Amgen.
The FDA has targeted an Agency action within ten months of the application's submission date, resulting in a Prescription Drug User Fee Act (PDUFA) action date of Oct. 19, 2009.
About Prolia(TM) (denosumab)
Prolia is the first fully human monoclonal antibody in late stage clinical development that specifically targets RANK Ligand, an essential regulator of osteoclasts (the cells that break down bone). Prolia is being investigated for its potential to inhibit all stages of osteoclast activity through a targeted mechanism. Prolia is being studied in a range of bone loss conditions including postmenopausal osteoporosis and bone loss in patients undergoing hormone ablation for prostate and breast cancer.
In February 2009, the U.S. Food and Drug Administration (FDA) accepted the Biologics License Application (BLA), submitted by Amgen for Prolia for the treatment and prevention of osteoporosis in postmenopausal women and cancer treatment-induced bone loss in women and men receiving hormone therapy for either breast cancer or prostate cancer based on these studies and a parallel trial in women with breast cancer. The FDA has provisionally approved the trade name Prolia in these proposed indications, for which denosumab is administered twice yearly subcutaneously at a 60mg dose. The Prolia trade name is only for these indications and may not apply for other indications of denosumab.
Amgen has also submitted marketing applications for use of Prolia in the European Union, Canada, Switzerland, and Australia.
Often referred to as the "silent epidemic," osteoporosis is a global problem that is increasing in significance as the population of the world both increases and ages. In the U.S. today, nearly eight million women suffer from osteoporosis.(i) The World Health Organization (WHO) has recently identified osteoporosis as a priority health issue along with other major non-communicable diseases.
The economic burden of osteoporosis is comparable to that of other major chronic diseases; for example, in the U.S., the costs associated with osteoporosis-related fractures are equivalent to those of cardiovascular disease and asthma.(ii,iii,iv) It has been reported that osteoporosis results in more hospital bed-days than stroke, myocardial infarction or breast cancer.(v)
Bone Loss Due to Hormone Ablation
In the U.S., prostate cancer is the most common cancer in men and breast cancer is the most common cancer in women. It is common for prostate cancer and breast cancer patients to receive hormone ablation therapies that can lead to a decrease in bone mass and increased risk of fractures. Currently there are no approved therapies for bone loss in patients undergoing hormone ablation for either prostate or breast cancer.

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 (SEC) reports filed by Amgen, including Amgen's most recent annual report on Form 10-K and most recent periodic reports on Form 10-Q and Form 8-K. Please refer to Amgen's most recent Forms 10-K, 10-Q and 8-K for additional information on the uncertainties and risk factors related to our business. Unless otherwise noted, Amgen is providing this information as of Aug. 13, 2009 and expressly disclaims any duty to update information contained in this news release.
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. 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 business may be impacted by government investigations, litigation and products liability claims. We depend on third parties for a significant portion of our manufacturing capacity for the supply of certain of our current and future products and limits on supply may constrain sales of certain of our current products and product candidate development.
In addition, sales of our products are affected by the reimbursement policies imposed by third-party payors, 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 as well as U.S. legislation affecting pharmaceutical pricing and reimbursement. Government and others' regulations and reimbursement policies may affect the development, usage and pricing of our products. In addition, we compete with other companies with respect to some of our marketed products as well as for the discovery and development of new products. We believe that some of our newer products, product candidates or new indications for existing products, may face competition when and as they are approved and marketed. Our products may compete against products that have lower prices, established reimbursement, superior performance, are easier to administer, or that are otherwise competitive with our products. In addition, 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 and there can be no guarantee of our ability to obtain or maintain patent protection for our products or product candidates. We cannot guarantee that we will be able to produce commercially successful products or maintain the commercial success of our existing products. Our stock price may be affected by actual or perceived market opportunity, competitive position, and success or failure of our products or product candidates. Further, 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.
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 (FDA), and no conclusions can or should be drawn regarding the safety or effectiveness of the product candidates.
