BOSTON, April 22, 2021 (GLOBE NEWSWIRE) -- Radius Health, Inc. (“Radius” or the “Company”) (Nasdaq: RDUS), provided the following business update. The Company’s first quarter 2021 earnings will take place on Friday, May 7 at 8:30am EST.

ABALOPARATIDE ASSET

TYMLOS

Patient growth increased by 14% in Q1, 2021 vs. Q4, 2020. For the first quarter, patient adds were strong in January, weakened in the short and weather impacted month of February, and rebounded in March. To date for the month of April, the new patient numbers appear robust.

Within the first quarter, there were seasonally driven headwinds for the net revenue totals. These are consistent with previous years, although Q1 2020 – as a comparator – was an unusual quarter given the underlying patient and HCP activity-based volatility resulting from COVID-19. We also experienced reasonable destocking within our distribution channel for the quarter. We expect net revenues will normalize throughout the balance of 2021.

Male Indication (ATOM Study)

Completed several human factors studies designed to evaluate the usability of the current commercial TYMLOS product. These formative human factors studies included both men and women, and the results were positive. We anticipate that the results will be included in an sNDA submission to add the male population to the label.

TD (wearABLe Study) Sterile Product and Human Factor Studies

Study completed to assess commercial sterile patch pharmacokinetic performance compared to the initial Phase 3 product. The results of the study were positive and passed the strict FDA bioequivalence criteria. This will enable a transition of all remaining patients in our wearABLe Phase 3 study from the current product to the sterile commercial product.

Final human factors studies were also completed, and the results were positive. This enables us to proceed to summative studies and would be an integral component in an anticipated abaloparatide-TD NDA submission.

ELACESTRANT ASSET

Pivotal data readout remains on track for 2H 2021. We continue to work closely with our partner, the Menarini Group, on execution, implementation, and progression of the program.

RAD011 ASSET

FDA Type C meeting is scheduled to take place in June, 2021. This meeting will review and discuss our proposed Phase 3 protocol for PWS. A recent advisory board meeting provided us with additional insights and considerations for the proposed pivotal trial.

Beyond PWS, the Company is critically assessing additional orphan indications that might be applicable for the RAD011 molecule. Several disease specific opportunities will be considered for clinical advancement over the course of the next 12 months.

The upcoming PWSA/USA Virtual Medical and Scientific Meeting will take place on June 23 and 24. The Company’s abstract “Preliminary results from a randomized, placebo-controlled Phase 2 trial using synthetic cannabidiol (CBD) oral solution in 7 individuals with Prader Willi Syndrome,” has been accepted. Results will be presented during an oral presentation.

About Radius

Radius is a commercialized 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 Phase 3 wearABLe study is the first pivotal study to evaluate treatment using a novel non-injectable delivery of an anabolic therapy. 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 Elacestrant (RAD1901) and EMERALD Phase 3 Study

Elacestrant is a selective estrogen receptor degrader (SERD), out-licensed to Menarini Group, which is being evaluated for potential use as a once daily oral treatment in patients with ER+/ HER2- advanced breast cancer. Studies completed to date indicate that the compound has the potential for use as a single agent or in combination with other therapies for the treatment of breast cancer. The EMERALD Phase 3 trial is a randomized, open label, active-controlled study evaluating elacestrant as second- or third-line monotherapy in ER+/HER2- advanced/metastatic breast cancer patients. The study has enrolled 466 patients who have received prior treatment with one or two lines of endocrine therapy, including a cyclin-dependent kinase (CDK) 4/6 inhibitor. Patients in the study were randomized to receive either elacestrant or the investigator’s choice of an approved hormonal agent. The primary endpoint of the study is progression-free survival (PFS) in the overall patient population and in patients with estrogen receptor 1 gene (ESR1) mutations. Secondary endpoints include evaluation of overall survival (OS), objective response rate (ORR), and duration of response (DOR).
