Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is evaluating the safety, tolerability, and efficacy of methylone in adults with PTSD. The study will be conducted in two parts.

* Part A is open-label and will enroll up to 15 participants with PTSD
* Part B is randomized (1:1), double-blind, placebo-controlled and will enroll up to 64 participants with PTSD

Eligible participants will enter a 4-week Treatment Period where they will receive methylone once weekly for 4 weeks (4 treatment sessions). Following the Treatment Period, participants will enter a 6-week Follow-up Period which includes 3 reflection visits (Week 4, 5, and 6) and a final study visit at Week 10.
