CAMBRIDGE, MA -- (Marketwire) -- 03/12/13 -- Radius Health, Inc. ("Radius"), a biopharmaceutical company focused on developing new therapeutics for the treatment of osteoporosis and other women's health conditions, today announced that it has completed enrollment for its pivotal Phase 3 study of BA058-subcutaneous, a bone-building synthetic peptide analog. BA058 is being developed in both subcutaneous (BA058-SC) and transdermal patch (BA058-TD) formulations for the treatment of osteoporosis in postmenopausal women at high risk of fracture.
Radius Health has reached the enrollment target of 2400 subjects in BA058-05-003 (see ClinicalTrials.gov), the pivotal Phase 3 trial for BA058-SC. The final subjects entering the trial have now been randomized. This randomized, double-blind, placebo-controlled trial compares BA058-SC daily injection to placebo for prevention of new vertebral fractures over 18 months of treatment as its primary endpoint. Forteo® is an active comparator arm of this study.
"This is a significant milestone for Radius, as we are treating a high risk osteoporosis patient population in 28 centers across the world," said Radius Health Chief Medical Officer Louis Brenner, MD. "We are grateful for the efforts of our patients, investigators, and research collaborators to bring the pivotal study of BA058-SC to this key point, and we look forward to their continued contributions through the treatment and follow-up phases of the study."
Top-line data from the Phase 2 study of BA058-SC demonstrated a significant increase in bone mineral density (BMD) at the lumbar spine and femoral neck (a common fracture site located in the hip joint) after six months of therapy in women with osteoporosis. BA058 was generally safe and well tolerated in this study. In addition, the occurrence of hypercalcemia was half that of Forteo® in the highest dose of BA058 tested.
"There is a significant unmet need with a large osteoporosis patient population, and those with severe osteoporosis who are at high risk for fracture have few treatment options," said Claus Christiansen, MD, a Radius Advisor, Chairman of the Board of Nordic Bioscience, founder of the Center for Clinical and Basic Research and author of more than 900 articles and books on osteoporosis. "Our team at Nordic Bioscience is deeply engaged in both the Phase 2 trial of BA058-TD and the pivotal Phase 3 trial of BA058-SC. We are excited to have contributed to the achievement of BA058's research milestones and we are optimistic about the potential for BA058 to provide a novel anabolic treatment option for postmenopausal osteoporosis patients."
In its transdermal patch formulation, BA058-TD is being studied in a randomized, double-blind, placebo controlled Phase 2 study in 250 healthy postmenopausal women with osteoporosis. Radius previously announced completion of enrollment in this study in January 2013. BA058-TD is a short wear-time transdermal patch based on 3M's patented Microstructured Transdermal System technology to administer BA058 without the need for subcutaneous injection. The study is designed to assess changes in bone mineral density (BMD) after six months of treatment. In addition, pharmacokinetic parameters and serum markers of bone metabolism for BA058-TD will be compared to both transdermal placebo and BA058-SC.
