A POC Clinical Trial for PTSD with a First-In-Class Vasopressin 1a Receptor Antagonist
Abstract
A sample of 33 patients were randomized to the two-arm crossover treatment vs. placebo trial. Randomization was balanced by sex and comorbid major depression. The primary outcome, CAPS-5 Severity, decreased significantly over the course of the study. Although the primary mixed effects model did not show significant treatment differences, the study was underpowered and only about half of the participants completed both crossover phases due to documented issues in recruiting. Examination of effect sizes adjusted by covariates suggested superiority for SRX246, a first-in-class vasopressin 1a receptor antagonist, with an effect about 30% higher than placebo. These preliminary findings suggest SRX246 may be an effective treatment for PTSD. If confirmed through additional clinical studies, SRX246 would represent a breakthrough in pharmacotherapy for PTSD, where effective treatments are needed for warfighters, veterans, and civilians.
