A Study to Assess the Use of Methylone in the Treatment of PTSD (IMPACT-1)

This Phase II, two-part, multicentre trial (n=64) will assess methylone as a treatment for adults with post-traumatic stress disorder (PTSD). It is designed to evaluate the drug’s safety, tolerability, and efficacy in participants aged 18–65 years in the UK, including people who have previously tried at least one PTSD treatment without sufficient benefit.

Detailed Description

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.

Efficacy and Safety of the Neuroplastogen TSND-201 for the Treatment of PTSD A Randomized Clinical Trial

In a multicentre, double‑blind, placebo‑controlled phase 2 trial of 65 adults with chronic PTSD, once‑weekly oral TSND‑201 produced significantly greater reductions in clinician‑rated PTSD severity (CAPS‑5; LS mean difference 9.64, P = .01) and improvements in self‑reported symptoms, functioning and depression versus placebo. TSND‑201 was generally well tolerated — common adverse events included headache, decreased appetite, nausea, dizziness and transient blood‑pressure increases — supporting its potential as a rapid‑acting, durable treatment for PTSD.
