Radius Announces FDA Acceptance for Filing of NDA for Abaloparatide-SC for the Treatment of Postmenopausal Women with Osteoporosis

WALTHAM, Mass., May 31, 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 its New Drug Application (NDA) for abaloparatide—SC has been accepted for filing by the U.S. Food and Drug Administration (FDA). The acceptance of the NDA reflects the FDA's determination that the application is sufficiently complete to permit a substantive review.

"The FDA's acceptance for filing of our abaloparatide-SC NDA is a major milestone for Radius and we look forward to continuing to work with the FDA as they review our application," said Robert E. Ward, President and CEO of Radius Health. "Given the high unmet medical need in osteoporosis, we believe that abaloparatide-SC, if approved, has the potential to become a promising new treatment option for the approximately 10 million postmenopausal women with osteoporosis, many of whom remain untreated."

The NDA is supported by data from the entire abaloparatide-SC development program, including the results from the 18-month Phase 3 ACTIVE trial in 2,463 postmenopausal women with osteoporosis and the first six months of the ACTIVExtend trial in 1,139 of the ACTIVE participants. Positive results for abaloparatide-SC treatment groups from the ACTIVE and ACTIVExtend trials have met the primary and secondary endpoints essential for submission of the NDA, including the primary endpoint of reduction of vertebral fractures as well as key endpoints of reduction of nonvertebral, clinical, and major osteoporotic fractures. In these and the other trials submitted in the NDA, abaloparatide-SC administered at a dose of 80 mcg daily was generally safe and well tolerated in postmenopausal women with osteoporosis.

As previously reported, Radius submitted a Centralised Marketing Authorisation Application (MAA) for abaloparatide-SC in the European Union on November 17, 2015, which was validated by the European Medicines Agency (EMA) in December 2015, and is currently undergoing active regulatory assessment by the Committee for Medicinal Products for Human Use of the EMA (CHMP). The EMA has granted Radius an additional 3-month extension to the procedural timetable for response in the ongoing MAA assessment. As a result of this extension to the procedural timetable, the Company now anticipates that the CHMP may adopt an Opinion regarding the MAA in late 2016 or in 2017.

Abaloparatide-SC is an investigational treatment for postmenopausal women with osteoporosis and its safety and efficacy have not been established.

About Abaloparatide

Abaloparatide is an investigational therapy for the potential treatment of postmenopausal women with osteoporosis. Abaloparatide is a novel synthetic 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). Radius' NDA for abaloparatide-SC was accepted for filing by the US Food and Drug Administration in May 2016, for the treatment of postmenopausal women with osteoporosis. In December 2015, Radius's MAA for abaloparatide-SC for the treatment of postmenopausal women with osteoporosis was validated by the European Medicines Agency for commencement of Centralised assessment by the Committee for Medicinal Products for Human Use (CHMP). The MAA is currently undergoing regulatory review by the CHMP.

Radius also is developing abaloparatide-transdermal (abaloparatide-TD) based on 3M's patented Microstructured Transdermal System technology for potential use as a short wear-time transdermal patch.
