  • Advances asset in the neuro-endocrine orphan disease space
  • SCOUT-015 clinical trial currently has 9 activated US sites and patient screening commenced
  • 30+ global sites are planned for the seamless Phase 2/3 pivotal trial
  • Primary endpoint of hyperphagia supplemented by key secondary endpoints
  • SCOUT-015 presentations will be shared at numerous conferences July to September

BOSTON, July 07, 2022 (GLOBE NEWSWIRE) -- Radius Health, Inc. ("Radius" or the "Company") (Nasdaq: RDUS) today announced the first patient has been randomized in the Phase 2/3 pivotal study, SCOUT-015, to evaluate RAD011, a synthetic cannabidiol oral solution, for the treatment of hyperphagia and related neuro-behavioral symptoms in Prader-Willi Syndrome (PWS), a rare neuro-endocrine orphan disease which effects between approximately 20,000 and 30,000 patients in the US.

The SCOUT-015 clinical study is a global randomized, double-blind, placebo-controlled study. It is a seamless Phase 2/3 design that allows for the evaluation of multiple dose groups and Intent-To-Treat efficacy analysis with both Phase 2 and Phase 3 cohorts.

Currently, 9 US sites are activated for screening and patient recruitment will continue across the US and globally as non-US sites are activated.

RAD011 has Orphan Drug Designation and has been granted Fast Track by the U.S. Food and Drug Administration (FDA).

Paige Rivard, Chief Executive Officer of Prader-Willi Syndrome Association|USA, said, “We are excited and encouraged by the achievement of this milestone and remain committed to supporting Radius’ recruitment and awareness efforts for their SCOUT-015 clinical trial within our community of patients, caregivers, and key opinion leaders. Continued enrollment within the trial is critically important to the advancement of RAD011, which if approved, has the potential for high impact on the PWS community and will bring a much-needed treatment choice to patients with hyperphagia.”

Radius will provide additional updates regarding the PWS trial with further advancements of the program.


There will be a number of SCOUT-015 presentations at upcoming conferences, including:

  • IPWSO (International Prader-Willi Syndrome Organisation)

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 125 patients across multiple indications and has potential utilization in multiple neuro-endocrine, neurodevelopmental, or neuropsychiatric disease areas. Radius has initiated a seamless pivotal Phase 2/3 study for patients with Prader-Willi Syndrome.
