What this trial studies

This study evaluates the safety and efficacy of methylone in adults diagnosed with PTSD. It consists of two parts: Part A is an open-label phase enrolling up to 15 participants, while Part B is a randomized, single-blind phase enrolling up to 45 participants. Participants will receive methylone once weekly during the treatment periods, which last three weeks for Part A and four weeks for Part B, followed by a follow-up period. The study aims to gather data on the effects of methylone on PTSD symptoms.

Who should consider this trial

Good fit: Ideal candidates are adults who meet DSM-5 criteria for severe PTSD and have tried at least one prior treatment.

Not a fit: Patients with primary diagnoses of other DSM-5 disorders or significant cardiovascular conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients suffering from PTSD.

How similar studies have performed: While the use of methylone for PTSD is a novel approach, similar studies evaluating neuroplastogens have shown promise in treating mental health conditions.
