Amgen and UCB present positive data at ENDO 2016  comparing romosozumab with teriparatide

  • In phase 3 open-label STRUCTURE study postmenopausal women with osteoporosis transitioning from oral bisphosphonate to romosozumab experienced consistent and significant gains in bone mass and estimated strength over teriparatide 

Brussels, Belgium, Thousand Oaks, Calif, April 1, 2016 – UCB (Euronext Brussels: UCB) and Amgen (NASDAQ: AMGN) today announced detailed Phase 3 results showing the investigational agent romosozumab demonstrated a statistically significant increase in hip bone mineral density (BMD) and strength compared with teriparatide in postmenopausal women with osteoporosis transitioning from bisphosphonate treatment. The data, from the randomized open-label, international, multi-center STRUCTURE study (STudy evaluating effect of RomosozUmab Compared with Teriparatide in postmenopaUsal women with osteoporosis at high risk for fracture pReviously treated with bisphosphonatE therapy), were presented during an oral session at ENDO 2016, the Endocrine Society’s 98th Annual Meeting & Expo in Boston.

“These findings are especially important because they show romosozumab provided significant hip bone improvements in a population that remained at high risk of fracture despite bisphosphonate therapy,” said Bente Langdahl, Ph.D., DMSc, professor and consultant in the department of endocrinology and internal medicine at the Aarhus University Hospital in Denmark and STRUCTURE investigator. “Across the primary and all secondary endpoints, patients transitioned from oral bisphosphonates to romosozumab showed consistent and significant gains in bone mass and estimated strength over teriparatide. At the hip, patients transitioned to teriparatide showed either no gains or significant decreases in these parameters.”

The trial included 436 women, averaging 72 years of age, with postmenopausal osteoporosis, a history of non-vertebral fracture after the age of 50, or vertebral fracture and treatment with bisphosphonate therapy for a minimum of three years prior to transitioning to romosozumab or teriparatide therapy. The women were randomly assigned to receive either subcutaneous romosozumab 210 mg once monthly (n=218) or subcutaneous teriparatide 20 mcg daily for 12 months (n=218).

The results showed that the percent change from baseline in BMD at the total hip through month 12, the primary endpoint, was significantly greater with romosozumab compared with teriparatide: 2.6 percent versus –0.6 percent, respectively (p<0.0001), for a mean difference between the two groups of 3.2 percent (p<0.0001). The measurement was based on the standard method of dual-energy x-ray absorptiometry (DXA).

For the secondary endpoints, patients treated with romosozumab had significantly larger increases from baseline in total hip BMD and strength compared with those receiving teriparatide, with mean differences ranging from 3.1 percent to 4.6 percent (all p-values <0.0001):

The overall incidence of adverse events was generally balanced between the two study arms. Incidence of all adverse events in patients treated with romosozumab was 75.2 percent compared to 69.2 percent with teriparatide. Serious adverse events occurred in 7.8 percent of patients treated with romosozumab compared to 10.7 percent for teriparatide. Adverse events reported in the romosozumab armgreater than or equal to 10 percent of patients were nasopharyngitis and arthralgia. Injection site reactions were reported in 7.8 percent.

About Romosozumab
Romosozumab is an investigational bone-forming monoclonal antibody and is not approved by any regulatory authority for the treatment of osteoporosis. It is designed to work by inhibiting the protein sclerostin, and has a dual effect on bone, both increasing bone formation and decreasing bone resorption.1,2,3 Romosozumab is being studied for its potential to reduce the risk of fractures in an extensive global Phase 3 program. This program includes two large fracture trials comparing romosozumab to either placebo or active comparator in more than 10,000 postmenopausal women with osteoporosis. Amgen and UCB are co-developing romosozumab.

About the STRUCTURE study (NCT01796301)
STRUCTURE (STudy evaluating effect of RomosozUmab Compared with Teriparatide in postmenopaUsal women with osteoporosis at high risk for fracture pReviously treated with bisphosphonatE therapy) was a Phase 3, multi-center, international, randomized, open-label, teriparatide-controlled study that evaluated safety, tolerability and efficacy of romosozumab in women with postmenopausal osteoporosis. The trial included 436 postmenopausal women averaging 72 years of age who had postmenopausal osteoporosis and a history of bone fracture; patients were treated with bisphosphonate therapy for a minimum of three years prior to screening, with treatment with alendronate (70 mg weekly or equivalent) during the year immediately prior to screening. The women received daily calcium and vitamin D and were randomly assigned to receive either subcutaneous romosozumab 210 mg once monthly (n=218), administered by a health care professional, or self-administered subcutaneous teriparatide 20 mcg daily for 12 months (n=218).

The primary endpoint was percent change from baseline in total hip BMD by DXA through month 12 (average of the changes at months six and 12). Key secondary endpoints included percent change from baseline at months six and 12 in total hip BMD by DXA; hip integral and cortical BMD by QCT, a method to measure BMD changes in three dimensions; and estimated hip strength by finite element analysis (FEA). FEA is a validated method that utilizes QCT scans to simulate compression overload to estimate vertebral strength, and a sideways fall to estimate femoral strength. Other secondary endpoints included lumbar spine and femoral neck BMD by DXA at months six and 12.

About Osteoporosis
Osteoporosis affects many women after menopause as their ability to form new bone cannot counter balance the rate at which bone is being removed.1,2 This bone loss leads to weakened bones over time, increasing the potential for a break.3

It is estimated that one in three women over the age of 50 will experience an osteoporotic fracture.4,5 Patients who experience an osteoporosis-related fracture are twice as likely to experience a future fracture.6

The World Health Organization has officially declared osteoporosis a public health crisis7,8 and the International Osteoporosis Foundation urges governments worldwide to make osteoporosis a healthcare priority.9

Forward-Looking Statements – Amgen
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. 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 related to our product candidates is preliminary and investigative. Such product candidates are not approved by the U.S. Food and Drug Administration or European Commission, and no conclusions can or should be drawn regarding the safety or effectiveness of the product candidates.
