-Post-hoc analysis suggests abaloparatide may be useful in the treatment of women with postmenopausal osteoporosis and concurrent osteoarthritis, at high risk for fracture- -Preclinical studies provide explanations for the net bone gain observed in the Phase 3 ACTIVE trial in abaloparatide-treated patients- WALTHAM, Mass., March 23, 2019 (GLOBE NEWSWIRE) -- Radius Health, Inc. (Nasdaq: RDUS), a science-driven fully integrated biopharmaceutical company that is committed to developing and commercializing innovative endocrine therapeutics in the areas of osteoporosis and oncology, today presented a post-hoc analysis of Phase 3 data from different patient populations included in the ACTIVE trial, and results from preclinical studies of abaloparatide and its effect on the development and growth of osteoclasts and on bone resorption during an oral session at ENDO 2019, the Endocrine Society’s Annual Meeting and Expo in New Orleans, LA. The first oral presentation titled “The Effect of Abaloparatide on Bone Mineral Density and Fracture Incidence in Postmenopausal Women with Osteoporosis and Osteoarthritis,” showed that in a subpopulation of postmenopausal women from the ACTIVE study who also had osteoarthritis (OA), abaloparatide was associated with significant reduction in new vertebral fractures as well as significant improvements in bone mineral density (BMD), versus placebo. The relationship between OA and osteoporosis is unclear but increased risk of fragility fracture has been associated with OA despite those patients having higher than average BMD. Of the 2,463 women enrolled in the Phase 3 ACTIVE trial, 888 patients with ongoing OA were identified. The most common sites of OA were at the spine (n=348, 39.2 percent) and knee (n=338, 38.1 percent). At 18 months, significant increases (P<0.0001) in BMD from baseline were observed for abaloparatide versus placebo at the total hip (mean change 3.17 percent versus -0.35 percent), femoral neck (2.81 percent versus -0.36 percent), and lumbar spine (8.78 percent versus 0.86 percent); which was consistent with the overall ACTIVE population results. “Many patients with osteoporosis also have osteoarthritis. This post-hoc analysis of the pivotal ACTIVE clinical trial provides important information regarding the effects of abaloparatide in this patient population,” said John P. Bilezikian, M.D., Chief, Emeritus, of the Division of Endocrinology and Director, Emeritus, of the Metabolic Bone Diseases Program at the Vagelos College of Physicians and Surgeons, Columbia University Medical Center. “Results from this analysis suggest abaloparatide may be useful as a therapy of postmenopausal women with osteoporosis who also have osteoarthritis and are at high risk for fracture.” The second oral presentation titled “Different Effects of Abaloparatide and hPTH(1-34) on Osteoclastogenesis and Bone Resorption” used data from preclinical studies of abaloparatide. The analysis provides mechanistic explanations for the net bone gain observed in the ACTIVE trial, indicating that increased bone mass is, at least partly, the consequence of reduced osteoclast (bone resorption) activity. “We’re pleased to share this new analysis in women who have postmenopausal osteoporosis and osteoarthritis, as well as data from preclinical studies that may explain the increased bone mass observed in abaloparatide-treated patients,” said Bruce Mitlak, M.D., Vice President of Clinical Development at Radius Health. “We are committed to providing information about abaloparatide to help inform treatment decisions for healthcare professionals managing women with postmenopausal osteoporosis.” Separately, Radius Health will present a poster titled: “Effect of Abaloparatide on Bone Mineral Density and Fracture Incidence in a Subset of Younger Postmenopausal Women with Osteoporosis at High Risk for Fracture Representative of Covered Commercial Insurance Enrollees.” About Postmenopausal Osteoporosis The National Osteoporosis Foundation (NOF) has estimated that nearly 8.2 million women in the U.S. over the age of 50 have osteoporosis, and nearly one in two women over the age of 50 will have a fragility fracture (or low-impact fracture that is often the result of a fall from standing height or lower) in her remaining lifetime. The annual incidence of osteoporotic fractures is higher than that of stroke, heart attack and breast cancer combined; osteoporotic fractures also account for more hospitalizations and associated costs than cardiovascular disease and breast cancer. About TYMLOS (abaloparatide) injection About ACTIVE IMPORTANT SAFETY INFORMATION WARNING: RISK OF OSTEOSARCOMA
Orthostatic Hypotension: Orthostatic hypotension may occur with TYMLOS, typically within 4 hours of injection. Associated symptoms may include dizziness, palpitations, tachycardia or nausea, and may resolve by having the patient lie down. For the first several doses, TYMLOS should be administered where the patient can sit or lie down if necessary. Hypercalcemia: TYMLOS may cause hypercalcemia. TYMLOS is not recommended in patients with pre-existing hypercalcemia or in patients who have an underlying hypercalcemic disorder, such as primary hyperparathyroidism, because of the possibility of exacerbating hypercalcemia. Hypercalciuria and Urolithiasis: TYMLOS may cause hypercalciuria. It is unknown whether TYMLOS may exacerbate urolithiasis in patients with active or a history of urolithiasis. If active urolithiasis or pre-existing hypercalciuria is suspected, measurement of urinary calcium excretion should be considered. Adverse Reactions: The most common adverse reactions (incidence ?2%) are hypercalciuria, dizziness, nausea, headache, palpitations, fatigue, upper abdominal pain and vertigo. INDICATIONS AND USAGE Limitations of Use Because of the unknown relevance of the rodent osteosarcoma findings to humans, cumulative use of TYMLOS and parathyroid hormone analogs (e.g., teriparatide) for more than 2 years during a patient's lifetime is not recommended.
