MDMA (3,4-methylenedioxymethamphetamine), commonly known as “ecstasy,” has been used for both recreational and therapeutic purposes since the 1970s. While risky recreationally, MDMA is shown to be safe and effective for post-traumatic stress disorder (PTSD) when used with psychotherapeutic support in controlled settings. MDMA enhances therapy by fostering trust, openness, and empathy while maintaining clarity. In 2017, the FDA designated MDMA therapy for PTSD as a breakthrough treatment, but in 2024 requested more phase III trial data after rejecting its approval. Research is also currently underway to explore the use of MDMA in treating other psychiatric disorders. This master’s thesis examines clinical indications for MDMA trials, evaluates the therapy’s efficacy and safety, and analyzes study methodologies. For this purpose, we analyzed all registered MDMA clinical trials, their status, and indications listed on ClinicalTrials.gov. We found that the majority of MDMA trials are completed and focused on PTSD as the main indication. Additionally, we reviewed relevant scientific articles from the PubMed database. From all available literature, we selected 10 key studies and analyzed them in detail regarding their efficacy, safety, and methodology. Our findings show that MDMA-assisted therapy produces consistent and statistically significant reductions in PTSD symptoms and holds promise for treating other mental health conditions, such as anxiety and depression. The therapy was generally well tolerated under controlled clinical conditions, with most reported adverse effects being mild to moderate in severity and rarely leading to study discontinuation. The majority of studies were randomized, double-blind, and placebo-controlled, with protocols that were precisely pre-defined. MDMA-assisted therapy typically involves three phases: preparatory sessions, experimental sessions (with MDMA), and integration session. Participants undergo medical screening before enrollment, followed by preparatory sessions to establish trust with a male–female therapy team. MDMA sessions last 6 to 8 hours, with an optional supplemental dose. Each is followed by several integration sessions, during which participants process their experiences. The therapeutic approach is individually tailored, with the environment designed to be safe, aesthetically calming, and home-like. The most effective outcomes for PTSD treatment have been observed with MDMA doses ranging between 75 and 125 mg. Overall, we conclude that this type of therapy has great potential but requires further research to confirm its long-term safety and effectiveness.
