What is MDMA-assisted therapy?
MDMA-assisted therapy combines carefully controlled, pharmaceutical-grade MDMA with a structured therapeutic programme including preparation, supervised dosing sessions and subsequent integration therapy—it is the combined treatment, not MDMA taken on its own, that is being researched.
Why is it being researched?
Research suggests MDMA may temporarily reduce fear and threat responses and increase openness and engagement, potentially enabling people with severe PTSD to work with traumatic memories that are otherwise overwhelming.
Who will the research help?
The research is intended to help people living with severe PTSD, particularly those who have not responded adequately to established treatments, with the proposed UK study expected to include veterans, first responders and war correspondents.
How is it regulated?
MDMA is currently a Class A, Schedule 1 controlled drug in the UK, so clinical research requires the appropriate clinical-trial approvals and strict Home Office-controlled-drug licensing and safeguards.
Is it legal in this setting?
Yes—Schedule 1 drugs can lawfully be used for legitimate clinical research under the necessary licences and approvals, although MDMA-assisted therapy is not currently an MHRA-authorised treatment for PTSD in the UK.
What evidence already exists?
Two international Phase 3 trials have reported greater reductions in PTSD symptoms with MDMA-assisted therapy than with the same therapeutic programme plus placebo, although the treatment remains investigational and these studies do not establish superiority over existing PTSD treatments.
How is patient safety managed?
Participants receive known, pharmaceutical-grade MDMA at controlled doses within a screened, medically supervised therapeutic protocol.
Who is delivering the trial?
SWV is preparing a UK clinical trial with Cambridge & Peterborough NHS Trust (CPFT) and Cambridge University subject to the necessary clinical-trial and controlled-drug approvals.
