What this trial studies

This Phase IIa clinical trial aims to evaluate the safety and efficacy of CORT108297, a selective glucocorticoid receptor antagonist, in treating PTSD symptoms among veterans. The study involves a randomized, double-blind, placebo-controlled design where participants will receive either the drug or a placebo for seven days. Veterans will undergo screening procedures, including psychological interviews and medical evaluations, and will be monitored through several follow-up visits to assess changes in PTSD symptoms. The trial seeks to gather pilot efficacy data to inform future studies on this treatment approach.

Who should consider this trial

Good fit: Ideal candidates are veterans with chronic PTSD who meet specific eligibility criteria, including a minimum score on the CAPS-5 assessment.

Not a fit: Patients with a history of certain psychiatric disorders or substance use disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for veterans suffering from PTSD.

How similar studies have performed: Previous studies have indicated that cortisol-blocking medications may be beneficial for treating PTSD, suggesting a promising avenue for this approach.
