Radius Announces Positive Top-Line Results from Completed ACTIVExtend Study for TYMLOS™ in Postmenopausal Women with Osteoporosis

ACTIVExtend trial demonstrated sustained statistically significant fracture risk reduction through the 3.5 years of sequential therapy: TYMLOS followed by an antiresorptive 

Safety similar among all treatment groups with no cases of ONJ or AFF across the entire TYMLOS development program

Planned sNDA submission of final ACTIVExtend study and presentation at future scientific conferences

Company to Host Top Line Results and Launch Update Webcast Today (Wednesday, May 24, 2017) at 4:30 p.m. ET

WALTHAM, Mass., May 24, 2017 (GLOBE NEWSWIRE) -- Radius Health, Inc. (Nasdaq:RDUS) a science-driven fully integrated biopharmaceutical company that is committed to developing innovative therapeutics in the areas of osteoporosis, oncology and endocrine diseases, today announced positive top-line results from the completed 24 month ACTIVExtend trial, which met all of its primary and secondary endpoints. In ACTIVExtend, patients who had completed 18 months of TYMLOS (abaloparatide) injections or placebo in the ACTIVE Phase 3 trial were transitioned to receive 24 additional months of open-label alendronate.

 "There is a substantial unmet medical need among postmenopausal women with osteoporosis at high risk of a fracture and we believe that these women deserve access to proper diagnosis and early intervention," said Dr. Lorraine Fitzpatrick, Radius Health's Chief Medical Officer. "Patients who have had a fracture are at a five-fold risk of a subsequent fracture and reducing fracture risk should be the goal of treatment."

"We are extremely pleased with the results of the landmark ACTIVExtend trial which provides physicians, payers and patients with new insights into a treatment paradigm which targets building bone with an anabolic first line and then extending the benefit of fracture risk reduction with a low cost antiresorptive agent," said Dr. Bruce Mitlak, Radius Health's Vice President of Clinical Development. "The results from this program demonstrate that TYMLOS followed by alendronate can support this paradigm with sustained fracture risk reduction through 3.5 years."

About TYMLOS (abaloparatide)

TYMLOS (abaloparatide) was approved by the U.S. Food and Drug Administration or the treatment of postmenopausal women with osteoporosis at high risk for fracture defined as history of osteoporotic fracture, multiple risk factors for fracture, or patients who have failed or are intolerant to other available osteoporosis therapy. Radius' Marketing Authorisation Application (MAA) for abaloparatide-SC for the treatment of women with postmenopausal osteoporosis was validated and is currently undergoing regulatory review by the European Medicines Agency (EMA).

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.

About ACTIVE and ACTIVExtend

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 abaloparatide-SC 80 mcg to reduce the risk of vertebral and nonvertebral fractures. The results of ACTIVE were published in the Journal of the American Medical Association in August of 2016. ACTIVExtend, an extension of ACTIVE, enrolled patients who had completed 18 months of abaloparatide-SC or placebo in ACTIVE to receive up to 24 additional months of open-label alendronate. The results of the first six months of ACTIVExtend were published in the Mayo Clinic Proceedings in February of 2017.

About "Together with TYMLOS" Program
TYMLOS will be available in the United States in June. For eligible patients, Radius Health will offer the "Together with TYMLOS" support program. For more information please visit www.togetherwithTYMLOS.com or call 1-866-TYMLOS4 (1-866-896-5674) between 8 am and 8 pm EST, Monday through Friday.

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
TYMLOS is indicated for the treatment of postmenopausal women with osteoporosis at high risk for fracture defined as a history of osteoporotic fracture, multiple risk factors for fracture, or patients who have failed or are intolerant to other available osteoporosis therapy. In postmenopausal women with osteoporosis, TYMLOS reduces the risk of vertebral fractures and nonvertebral fractures.

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.

About Osteoporosis

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

The National Osteoporosis Foundation (NOF) has estimated that eight million women already have osteoporosis, and another approximately 44 million may have low bone mass placing them at increased risk for osteoporosis.

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 Radius

Radius is a science-driven fully integrated biopharmaceutical company that is committed to developing and commercializing innovative therapeutics in the areas of osteoporosis, oncology and endocrine diseases.

Radius' Marketing Authorisation Application (MAA) for abaloparatide-SC for the treatment of postmenopausal women with osteoporosis is under regulatory review in Europe. The Radius clinical pipeline includes an investigational abaloparatide transdermal patch for potential use in postmenopausal women with osteoporosis and the investigational drug elacestrant (RAD1901) for potential use in hormone-driven and/or hormone-resistant breast cancer, and vasomotor symptoms in postmenopausal women. Radius' RAD140, a non-steroidal, selective androgen receptor modulator (SARM), is under investigation for potential use in hormone receptor positive breast cancer.
