Aytu BioPharma Announces Initiation of the AR101 PREVEnt Trial for the Treatment of Vascular Ehlers-Danlos Syndrome

The specialty pharmaceutical company,  AytuBio Pharma, announced the initiation of the global Phase 3 PREVEnt (Prevention of Ruptures with Enzastaurin for Vascular Ehlers-Danlos Syndrome) clinical trial. This study will be investigating the ability of enzastaurin to reduce the severe complications of vascular Ehlers-Danlos syndrome (vEDS). There are currently no FDA-approved therapies for vEDS.  

What is the PREVEnt trial?  

The PREVEnt Trial is a prospective, Phase 3, global, randomized, double-blind, placebo-controlled efficacy trial designed to evaluate enzastaurin in patients with genetically confirmed COL3A1-positive VEDS. The primary measure of the trial is to determine whether enzastaurin reduces the occurrence of VEDS-related arterial events (ruptures, dissections, pseudoaneurysms, carotid-cavernous fistula, aneurysm) requiring medical intervention compared to placebo. 

 The PREVEnt Trial will see Aytu BioPharma, Inc. enroll approximately 260 COL3A1-positive vEDS patients. The study will randomize patients 1:1, with half receiving enzastaurin 500 mg once daily along with the standard of care and half receiving a placebo once daily along with the standard of care. The study’s primary endpoint is a reduction in fatal and non-fatal arterial events (ruptures, dissections, pseudo-aneurysms).  

How to take part in the clinical trial
