Pivotal Phase III trial of abaloparatide-SC in Japanese women and men with osteoporosis achieves primary endpoint

Radius partner Teijin Pharma has submitted a New Drug Application for abaloparatide-SC for treatment of osteoporosis in Japan

WALTHAM, Mass., May 27, 2020 (GLOBE NEWSWIRE) -- Radius Health, Inc. (“Radius” or the “Company”) (Nasdaq: RDUS), today announced that its partner, Teijin Pharma Limited, has submitted a New Drug Application for abaloparatide-SC in Japan for the treatment of osteoporosis in patients who are at high risk for fractures.

The application is based on the positive results of the Phase III clinical study of abaloparatide-SC in Japan which included osteoporosis patients at high risk for fracture. The study achieved its efficacy endpoint with a significant increase in lumbar spine bone mineral density at 18 months and showed an acceptable safety profile. Detailed results of this trial are planned to be presented at a global medical conference in the second half of this year.

“We are pleased that our partner Teijin has achieved this significant milestone toward the potential introduction of abaloparatide as a new treatment option for osteoporosis patients,” stated Kelly Martin, CEO of Radius. “Japan represents the largest anabolic market in the world. This is a critically important step in expanding our osteoporosis business globally.”

“Under the Teijin Group’s current medium-term management plan, we are contributing to sustainability by developing solutions for a demographic change and increased health consciousness,” said Ichiro Watanabe, president of Teijin Pharma Limited. “Launching abaloparatide will be a key factor in our implementation of this plan, so we hope to obtain approval and begin marketing to improve patients’ quality of life (QOL) as soon as possible.”

It is estimated that there are 13 million patients1 with osteoporosis in Japan. Fractures associated with osteoporosis can restrict patients’ activities of daily living and reduce their quality of life dramatically. Therapies – such as abaloparatide-SC, that increase bone mass and decrease risk for subsequent fractures, will provide a meaningful treatment option for physicians and their patients.

The market for osteoporosis drugs in Japan reached USD 3 billion in 2019. Under its license and development agreement with Teijin, Radius is entitled to receive milestone payments upon achievement of certain regulatory and sales milestones and a fixed double-digit royalty based on net sales of abaloparatide-SC in Japan during the royalty term.
