Radius Health Provides Business Update on Bone Health

  • Exclusive extension of research discovery collaboration with Mass General Hospital (MGH)
  • Focus of the program: development of novel oral SIK inhibitors for musculoskeletal diseases
  • Extension of activity is based on data from existing collaboration which generated nonclinical molecule data demonstrating oral activity of the skeletal anabolic
  • TYMLOS® IP: additional patent issued that extends patent protection to January 10, 2040

BOSTON, March 08, 2022 (GLOBE NEWSWIRE) -- Radius Health, Inc. (“Radius” or the “Company”) (NASDAQ: RDUS) provided an update on business development and intellectual property progress in its Bone Health franchise.

Massachusetts General Hospital Research Collaboration

On December 15, 2020, Radius announced a discovery research collaboration with Massachusetts General Hospital (MGH) to evaluate novel oral salt-inducible kinase (SIK) inhibitors in an array of musculoskeletal diseases.

Over the past year, the teams achieved their collective goal of demonstrating skeletal anabolic activity of a candidate oral SIK inhibitor. This tangible progress has provided the foundation for both extending the research collaboration and agreeing to an exclusive license agreement with the objective of progressing a molecule for the treatment of musculoskeletal disorders including, but not limited to, osteoporosis.

Dr. Marc Wein M.D., Ph.D., investigator in the Department of Endocrinology at Massachusetts General Hospital with clinical focus on osteoporosis and metabolic bone diseases is the main collaborator with Radius. Dr. Wein’s research first described the role of SIKs in mediating the actions of parathyroid hormone (PTH) in bone.

The agreement also incorporates any application beyond musculoskeletal disorders as literature points to significant therapeutic opportunity due to the central role of the SIK pathway in a broad array of diseases.

Marc Wein M.D. Ph.D. of MGH commented, “Oral bone building medications for osteoporosis remain a major unmet medical need. This collaboration combines our knowledge about the parathyroid hormone signaling pathway with clinical development of new bone anabolic medications. This is a perfect opportunity to move discoveries from the laboratory toward patients.”

Beate Lanske, Ph.D., VP of Discovery Science at Radius who leads the program, added, “We are impressed and encouraged by the data generated during the past year. Our focus from here is progressing a lead optimization program by utilizing a network of external collaborators, including Dr. Wein.”

Bruce Mitlak M.D., the Chief Medical Officer of Radius, commented, “This is a fantastic opportunity for Radius to work with a talented global thought leader and investigator to develop an oral, bone building therapeutic to address the needs of patients with osteoporosis and other musculoskeletal disorders.”

Continuing to Strengthen TYMLOS Intellectual Property

The United States Patent and Trademark Office (USPTO) has granted patent 11,255,842, which extends TYMLOS patent exclusivity to January 10, 2040.

James Harrington, Global Chief Intellectual Property Counsel at Radius, commented, “The issuance of US Patent 11,255,842 extends protection for TYMLOS to January 10, 2040. Our core five issued patents – all covering TYMLOS – provide us with significant depth and breadth in protecting the commercial runway of our asset. By extending the duration of the molecule and deepening the IP protection on multiple levels, we provide a foundation for maximizing the life cycle activity including the launch of the male indication, pre-clinical assessment of a weekly or bi-weekly depot delivery, and the scientific advancement of a possible oral anabolic therapy with the MGH collaboration on SIK inhibitors.”

About Radius
Radius is a global biopharmaceutical company focused on addressing unmet medical needs in the areas of bone health, orphan diseases, 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. 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 neuro-endocrine, neurodevelopmental, or neuropsychiatric disease areas, initially targeting Prader-Willi syndrome, Angelman syndrome, and infantile spasms.

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.
