BOSTON, July 27, 2021 (GLOBE NEWSWIRE) — Radius Health, Inc. (“Radius” or the “Company”) (NASDAQ: RDUS), provided a business update today on the Company’s progress.

Abaloparatide

New patient adds for the U.S. TYMLOS business continue to grow. New TYMLOS patients in Q2, 2021 were up over 40% vs. the same period in 2020. New patients are defined as those patients who have been prescribed TYMLOS and subsequently filled their first prescription.

The Company’s focus on fracture patients and corresponding healthcare providers – as the primary patient target for TYMLOS – is deepening. To date in 2021, 80+% of our top 50 TYMLOS prescribers are fracture / bone health focused, a trend we see accelerating.

From a U.S. regulatory point of view, both pivotal studies, ATOM (Osteoporotic Men at High Risk of Fracture) and wearABLe (Transdermal System) are on track for topline readouts in 2H, 2021. Pending the wearABLe trial results and FDA approval, the Company intends to price the Transdermal System at a premium to TYMLOS.

On the European regulatory front, Radius completed scientific consultations with several EU member states in Q1, 2021, submitted a letter of intent to resubmit, completed a dossier review with the EMA, and is on track refile in Q4, 2021.

RAD011

The Company received clarity from the FDA following the Type C meeting in June. Radius plans to move forward with a seamless Phase 2/3 pivotal trial for PWS. RAD011 had previously been granted Orphan Drug and Fast Track Designation by the FDA.

Based on current plans, the pivotal trial will initiate in Q4, 2021 or Q1, 2022, with anticipated topline readout in the second half of 2024.

There are approximately 22,000 to 24,000 PWS patients in the U.S. To date, there are no approved therapies to treat the hyperphagia experienced with the disease. The Company is committed to working closely with caregivers, advocacy groups, and regulators – globally – to safely advance RAD011 for this orphan disease.

Radius’ goal: through the pivotal trial and subsequent data readout, demonstrate efficacy and safety for FDA approval, and to help patients living with PWS.

About Radius
Radius is a commercial biopharmaceutical company committed to serving patients with unmet medical needs in endocrinology and other therapeutic areas. 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. The Radius clinical pipeline includes investigational abaloparatide injection for potential use in the treatment of men with osteoporosis; an investigational abaloparatide transdermal system for potential use in the treatment of postmenopausal women with osteoporosis; the investigational drug, elacestrant (RAD1901), for potential use in the treatment of hormone-receptor positive breast cancer out-licensed to Menarini Group; and the investigational drug RAD011, a synthetic cannabidiol oral solution with potential utilization in multiple endocrine and metabolic orphan diseases, initially targeting Prader-Willi syndrome.

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.

About ATOM Phase 3 Study
The ATOM Phase 3 study is a randomized, double-blind, placebo-controlled study to assess efficacy and safety of abaloparatide injection in 228 men with osteoporosis. The primary endpoint is change in lumbar spine BMD at 12 months compared with placebo, and if successful, will form the basis of a supplemental NDA seeking to expand the use of TYMLOS to treat men with osteoporosis at high risk for fracture.

About the Abaloparatide Transdermal System and wearABLe Phase 3 Study
The abaloparatide transdermal system was developed in a collaboration between Radius and Kindeva Drug Delivery (“Kindeva”) (formerly 3M Drug Delivery Systems) with the application of Kindeva’s innovative microstructured transdermal system technology. The wearABLe study is a pivotal, randomized, open label, active-controlled, bone mineral density (“BMD”) non-inferiority bridging study that will evaluate the efficacy and safety of abaloparatide transdermal system versus TYMLOS (abaloparatide) injection in approximately 500 patients with postmenopausal osteoporosis at high risk for fracture. The primary endpoint of the study is the percentage change in lumbar spine BMD at 12 months.

About Prader-Willi Syndrome
PWS, an orphan disease, is a complex genetic disorder with clinical manifestations on the endocrine and neurological systems. Clinical signs of PWS develop throughout childhood, with hyperphagia and anxiety ranked as the key clinical features seeking medical attention by caregivers of individuals with PWS. Hyperphagia is a relentless, insatiable, pathological drive to eat that requires caregivers to strictly manage access to food through the locking of cabinets and refrigerators. PWS is recognized as the leading genetic cause of life-threatening obesity in children. As life-threatening hyperphagia persists into adulthood, metabolic syndrome expressed through obesity and diabetes can develop and contribute to morbidity and mortality. In addition to food-related behaviors, the behavioral symptoms commonly observed in PWS include high irritability, habitual skin picking, oppositional defiance and cognitive rigidity. There are currently no approved therapies to treat this disorder’s hyperphagia, irritability, or metabolic aspects. In the U.S., PWS occurs in approximately one out of every 15,000 births.

About RAD011
Investigational drug RAD011 is a pharmaceutical-grade synthetic cannabidiol oral solution, manufactured utilizing traditional pharmaceutical manufacturing processes. The product has purity specifications that meet standardized regulatory and quality control requirements and, compared to the process of developing a plant-derived product, the synthetic manufacturing process usually enables increased consistency and greater precision in the product supply. RAD011 has been assessed in over 150 patients across multiple indications and has potential utilization in multiple endocrine and metabolic orphan diseases. Radius is initially targeting Prader-Willi syndrome (PWS) and anticipates initiating a seamless pivotal Phase 2/3 study for patients with PWS in the fourth quarter of 2021 or first quarter of 2022.
