Results show consistency of Abaloparatide-SC responses across a wide range of patient subgroups

WALTHAM, Mass., Sept. 18, 2016 (GLOBE NEWSWIRE) -- Radius Health, Inc. (Nasdaq:RDUS), a science-driven biopharmaceutical company that is committed to developing innovative therapeutics in the areas of osteoporosis, oncology and endocrine diseases, today announced that additional positive results from the Phase 3 ACTIVE (Abaloparatide Comparator Trial In Vertebral Endpoints) trial were published in the Journal of Bone and Mineral Research (JBMR).  

In the article “Effects of Abaloparatide-SC on Fracture and Bone Mineral Density in Subgroups of Postmenopausal Women with Osteoporosis and Varying Baseline Risk Factors” JBMR 2016 Sept 9 [Epub ahead of print] patients in the ACTIVE trial were stratified into prespecified subgroups of baseline risk factors, inclusive of BMD, prior fracture history and age, to determine the consistency of the response for abaloparatide-SC versus placebo. http://onlinelibrary.wiley.com/doi/10.1002/jbmr.2991/epdf

“Results from the Phase 3 ACTIVE trial show that abaloparatide-SC may provide substantial benefit for a broad range of postmenopausal women with osteoporosis irrespective of their baseline risk factors, including age and prior fracture history,” said Dr. Felicia Cosman, M.D., osteoporosis specialist and Medical Director of the Clinical Research Center at Helen Hayes Hospital, Senior Clinical Director of the National Osteoporosis Foundation, Professor of Medicine at Columbia University, consultant to Radius and lead author of the paper. “These data are important for the large number of postmenopausal women who may be at risk of a fracture and show that anabolic therapy could provide more consistent, potent and early benefits and may be the most efficient way for these patients to achieve ultimate bone mineral density goals.”

“We are pleased to have these findings published in JBMR, as well as the opportunity to present additional scientific information about abaloparatide-SC as part of the American Society of Bone and Mineral Research 2016 Annual Meeting,” said Dr. Lorraine A. Fitzpatrick, Chief Medical Officer of Radius. “Approximately two million osteoporotic fractures occur annually in the U.S., which create physical and psychological burdens for those affected by diminishing their independence and quality of life. Radius Health is committed to pursuing new therapeutic options which have the potential to improve outcomes for these patients.”

Abaloparatide is an investigational treatment for postmenopausal women with osteoporosis and its safety and efficacy have not been established.  A Marketing Authorisation Application (MAA) for abaloparatide-SC for the treatment of patients with postmenopausal osteoporosis was validated and is currently undergoing regulatory review by the European Medicines Agency (EMA), and a New Drug Application (NDA) for abaloparatide is currently under review by the U.S. Food & Drug Administration (FDA).

About Postmenopausal Osteoporosis

Osteoporosis is a silent disease, often displaying no signs or symptoms until a fracture occurs, leaving a majority of patients undiagnosed and undertreated. Osteoporotic fractures create a significant healthcare burden, and represent a significant unmet medical need. An estimated two million osteoporotic fractures occur annually in the U.S., and this number is projected to grow to three million by 2025.

The National Osteoporosis Foundation (NOF) has estimated that 10 million people in the U.S., composed of eight million women and two million men, already have osteoporosis, and another approximately 44 million people have low bone mass placing them at increased risk for osteoporosis.

The debilitating effects of osteoporosis have substantial costs. When left untreated, osteoporosis leads to fractures which can have both physical and emotional consequences on a patient including pain and disability, inability to fully perform routine work or daily activities, and in some cases, result in death. 

About ACTIVE

The Phase 3 ACTIVE (Abaloparatide Comparator Trial In Vertebral Endpoints) trial was a randomized, double-blind, placebo-controlled, comparative, multicenter, 18 month international study in 2,463 postmenopausal women with osteoporosis designed to evaluate the efficacy and safety of the investigational drug abaloparatide-SC 80 mcg to reduce the risk of vertebral and nonvertebral fractures.  Miller PD et al,  “Effect of Abaloparatide vs Placebo on New Vertebral Fractures in Postmenopausal Women With Osteoporosis, A Randomized Clinical Trial” Journal of the American Medical Association 2016 Aug 16;316(7):722-733.

About Abaloparatide

Abaloparatide is an investigational therapy for the potential treatment of postmenopausal women with osteoporosis. Abaloparatide is a novel peptide that engages the parathyroid hormone receptor (PTH1 receptor) and was selected for clinical development based on its favorable bone building activity. 

Abaloparatide has completed Phase 3 development for potential use as a daily self-administered injection (abaloparatide-SC). In the fourth quarter of 2015, Radius’ Marketing Authorisation Application (MAA) for abaloparatide-SC for the treatment of patients with postmenopausal osteoporosis was validated and is currently undergoing regulatory review by the European Medicines Agency (EMA). Radius submitted a New Drug Application (NDA) for abaloparatide-SC to the US Food and Drug Administration (FDA) at the end of the first quarter of 2016, which has been accepted for filing with a PDUFA date of March 30, 2017. Radius also is developing abaloparatide-transdermal (abaloparatide-TD) based on 3M's patented Microstructured Transdermal System technology for potential use as a treatment for postmenopausal women with osteoporosis.
