At the 43-month timepoint, 60.7 percent (n=307/506) of abaloparatide followed by alendronate patients experienced BMD increases of more than 3 percent at all three sites (p<0.0001) compared with 24 percent (n=121/505) of patients who received placebo followed by alendronate. Increases of more than 6 percent at all three sites were experienced by 33.2 percent (n=168/506) of abaloparatide followed by alendronate patients compared with 4 percent (n=20/505) of patients who received placebo followed by alendronate (p<0.0001)."It's encouraging to see that the results from the ACTIVExtend Responder Analysis are consistent with the significant BMD response with TYMLOS versus placebo observed in ACTIVE," said Lorie Fitzpatrick, MD, Chief Medical Officer, Radius Health. Separately, ACTIVExtend BMD findings in risk subgroups are being presented at ENDO 2018 today at 1:00 p.m. CT in the poster presentation titled: "Fracture and Bone Mineral Density Response by Baseline Risk in Patients Treated with Abaloparatide Followed by Alendronate - Results from Phase 3 ACTIVExtend" (Leder). IMPORTANT SAFETY INFORMATION WARNING: RISK OF OSTEOSARCOMA
- Abaloparatide caused a dose-dependent increase in the incidence of osteosarcoma (a malignant bone tumor) in male and female rats. The effect was observed at systemic exposures to abaloparatide ranging from 4 to 28 times the exposure in humans receiving the 80 mcg dose. It is unknown if TYMLOS will cause osteosarcoma in humans.
- The use of TYMLOS is not recommended in patients at increased risk of osteosarcoma including those with Paget's disease of bone or unexplained elevations of alkaline phosphatase, open epiphyses, bone metastases or skeletal malignancies, hereditary disorders predisposing to osteosarcoma, or prior external beam or implant radiation therapy involving the skeleton.
- Cumulative use of TYMLOS and parathyroid hormone analogs (e.g., teriparatide) for more than 2 years during a patient's lifetime is not recommended.
Limitations of UseBecause 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 Postmenopausal Osteoporosis Osteoporosis is a silent disease, often displaying no signs or symptoms until a fracture occurs, leaving a majority of patients undiagnosed and undertreated. Osteoporotic fractures create a significant healthcare burden, and represent a significant unmet medical need. The majority (71 percent) of osteoporosis-related fractures in the U.S. among those 50 and older occur in women. 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 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 TYMLOS (abaloparatide) injection TYMLOS (abaloparatide) injection was approved by the U.S. Food and Drug Administration for 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 patch based on 3M's patented Microstructured Transdermal System technology for potential use as a treatment for postmenopausal women with osteoporosis.About Radius Radius is a science-driven fully integrated biopharmaceutical company that is committed to developing and commercializing innovative endocrine therapeutics in the areas of osteoporosis and oncology. Radius' lead product, TYMLOS (abaloparatide) injection, was approved by the U.S. Food and Drug Administration for the treatment of postmenopausal women with osteoporosis at high risk for fracture. 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 patch for potential use in osteoporosis; the investigational drug elacestrant (RAD1901) for potential use in hormone-receptor positive breast cancer; and the investigational drug RAD140, a non-steroidal, selective androgen receptor modulator (SARM) under investigation for potential use in hormone-receptor positive breast cancer.
