DCCR Clinical Trial Should Continue, Says Data Safety Monitoring Board

Based on the review of data from more than 50% of patients enrolled, the Data Safety Monitoring Board has recommended continuing a  phase III clinical trial of DCCR for PWS. The trial, called DESTINY PWS, is a randomized, double-blind, placebo-controlled study of once daily oral administration of DCCR versus placebo by Soleno Therapeutics, Inc. 

Role of the Data Safety Monitoring Board 

When a large clinical trial is conducted, data is often monitored and reviewed by a Data Safety Monitoring Board. This board is an independent group of experts who periodically review and evaluate the study data for participant safety, study conduct and progress, and when appropriate, efficacy. The monitoring board will make recommendations on whether to continue, modify or terminate a clinical trial, depending on how the data looks. 

This was the second planned Data Safety Monitoring Board Review of the phase III DESTINY PWS clinical trial. Both meetings resulted in the board recommending the continuation without modification of the trial. The outcome of this second meeting was based on the review of data from more than 50% of patients enrolled and treated.

DESTINY PWS Clinical Trial Background

DESTINY PWS is a Phase III, randomized, double-blind, placebo-controlled study of once daily oral administration of DCCR versus placebo in approximately 100 patients with a confirmed diagnosis of PWS. The primary endpoint is change from baseline hyperphagia score at week 13. Patients who complete DESTINY PWS have the option to enroll into C602, the open-label safety extension study.

In July 2018, the U.S. Food and Drug Administration designated the investigation of DCCR for the treatment of PWS to be a Fast Track development program. Prior to this, diazoxide choline received orphan designation for the treatment of PWS in the U.S. and in the E.U.

Susan Hedstrom is the Executive Director for the Foundation for Prader-Willi Research. Passionate about finding treatments for PWS, Susan joined FPWR in 2009 shortly after her son, Jayden, was diagnosed with Prader-Willi Syndrome. Rather than accepting PWS as it has been defined, Susan has chosen to work with a team of pro-active and tireless individuals to accelerate PWS research in order to change the future of PWS. Inspired by her first FPWR conference and the team of researchers that were working to find answers for the syndrome, she joined the FPWR team in 2010 and led the development of the One SMALL Step walk program. Under Susan’s leadership, over $15 million has been raised for PWS related research.
