Rationale
Posttraumatic stress disorder (PTSD) is a chronic condition that has wide-ranging negative effects on an individual’s health and interpersonal relationships. Treatments with long-term ...benefits are needed to promote the safety and well-being of those suffering from PTSD.
Objectives
To examine long-term change in PTSD symptoms and additional benefits/harms after 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for treatment of PTSD.
Methods
Participants received two to three active doses of MDMA (75–125 mg) during blinded or open-label psychotherapy sessions with additional non-drug therapy sessions. PTSD symptoms were assessed using the Clinician-Administered PTSD Scale for DSM IV (CAPS-IV) at baseline, 1 to 2 months after the last active MDMA session (treatment exit), and at least 12 months post final MDMA session (LTFU). A mixed-effect repeated-measures (MMRM) analysis assessed changes in CAPS-IV total severity scores. The number of participants who met PTSD diagnostic criteria was summarized at each time point. Participants completed a long-term follow-up questionnaire.
Results
There was a significant reduction in CAPS-IV total severity scores from baseline to treatment exit (LS mean (SE) = − 44.8 (2.82),
p
< .0001), with a Cohen’s
d
effect size of 1.58 (95% CI = 1.24, 1.91). CAPS-IV scores continued to decrease from treatment exit to LTFU (LS mean (SE) = − 5.2 (2.29),
p
< .05), with a Cohen’s
d
effect size of 0.23 (95% CI = 0.04, 0.43). The number of participants who no longer met PTSD criteria increased from treatment exit (56.0%) to LTFU (67.0%). The majority of participants reported benefits, including improved relationships and well-being, and a minority reported harms from study participation.
Conclusions
PTSD symptoms were reduced 1 to 2 months after MDMA-assisted psychotherapy, and symptom improvement continued at least 12 months post-treatment. Phase 3 trials are investigating this novel treatment approach in a larger sample of participants with chronic PTSD.

Rationale
Standard therapeutic approaches to reduce social anxiety in autistic adults have limited effectiveness. Since 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy shows promise ...as a treatment for other anxiety disorders, a blinded, placebo-controlled pilot study was conducted.
Objectives
To explore feasibility and safety of MDMA-assisted psychotherapy for reduction of social fear and avoidance that are common in the autistic population.
Methods
Autistic adults with marked to very severe social anxiety were randomized to receive MDMA (75 to 125 mg,
n
= 8) or inactive placebo (0 mg,
n
= 4) during two 8-h psychotherapy sessions (experimental sessions) in a controlled clinical setting. Double-blinded experimental sessions were spaced approximately 1 month apart with 3 non-drug psychotherapy sessions following each. The primary outcome was change in Leibowitz Social Anxiety Scale (LSAS) Total scores from Baseline to one month after the second experimental session. Outcomes were measured again six months after the last experimental session.
Results
Improvement in LSAS scores from baseline to the primary endpoint was significantly greater for MDMA group compared to the placebo group (
P
= 0.037), and placebo-subtracted Cohen’s
d
effect size was very large (
d
= 1.4, CI − 0.074, 2.874). Change in LSAS scores from baseline to 6-month follow-up showed similar positive results (
P
= 0.036), with a Cohen’s
d
effect size of 1.1 (CI − 0.307, 2.527). Social anxiety remained the same or continued to improve slightly for most participants in the MDMA group after completing the active treatment phase.
Conclusions
This pilot trial demonstrated rapid and durable improvement in social anxiety symptoms in autistic adults following MDMA-assisted psychotherapy. Initial safety and efficacy outcomes support expansion of research into larger samples to further investigate this novel treatment for social anxiety.

Introduction and purpose: Post-traumatic stress disorder is a psychiatric condition following an extreme event that causes a near death of an involved individual. Since conventional treatments using ...selective serotonin reuptake inhibitors do not consistently yield therapeutic success, alternative substances are being explored as potential solutions. This study aims to compile information regarding the outcomes of utilizing psychedelics in individuals diagnosed with PTSD. Brief description of the state of knowledge: In July 2023, after a number of clinical trials and 20-year-long efforts to overturn the impact of a prohibition, Australia became the first country to allow doctors, in clinical development and under strict control, to use the 3,4-methylenedioxymethamphetamine (MDMA) commonly known as ecstasy, as well as psylocybin in patients with post-traumatic stress disorder or depression 8. There is a noticeable annual growth of inquiries on PubMed involving the keywords "psychedelics" and "therapeutic", amounting to 92 in 2000 and topped by 738 searches in 2023, whereas the total number of results consists of 8415 positions. Therapeutic effects of psychedelics are becoming more recognized over time. Summary: Post-Traumatic Stress Disorder (PTSD) is a complex condition that affects both the psychological and somatic aspects of the body. Thus, a multidimensional intervention is indicated. The use of psychedelics might contribute to improvements not only in the severity of PTSD but also in depression or pain. Further research on a larger group of participants should be carried out to assess the potential role of psychedelics in conventional medicine in the future, alongside psychotherapy.
3,4-methylenedioxymethamphetamine (MDMA), a recreational drug, induces euphoric sensations and psychosocial effects, such as increased sociability and empathy. Serotonin, also called ...5-hydroxytryptamine (5-HT), is a neurotransmitter that has been associated with MDMA-induced prosocial effects. However, the detailed neural mechanisms remain elusive. In the present study, we investigated whether 5-HT neurotransmission in the medial prefrontal cortex (mPFC) and the basolateral nucleus of amygdala (BLA) is involved in MDMA-induced prosocial effects using the social approach test in male ICR mice. Systemic administration of (S)-citalopram, a selective 5-HT transporter inhibitor, before administration of MDMA failed to suppress MDMA-induced prosocial effects. On the other hand, systemic administration of the 5-HT1A receptor antagonist WAY100635, but not 5-HT1B, 5-HT2A, 5-HT2C, or 5-HT4 receptor antagonist, significantly suppressed MDMA-induced prosocial effects. Furthermore, local administration of WAY100635 into the BLA but not into the mPFC suppressed MDMA-induced prosocial effects. Consistent with this finding, intra-BLA MDMA administration significantly increased sociability. Together, these results suggest that MDMA induces prosocial effects through the stimulation of 5-HT1A receptors in the BLA.
•Systemic MDMA injection induces prosocial effects in the SA test.•MDMA-induced prosocial effects are mediated by 5-HT1A receptors in the BLA.•Intra-BLA administration of MDMA induces prosocial effects.
This paper provides a brief review of the history, proposed pharmacological mechanisms, safety issues, and clinical applications of the medicine 3,4-methylenedioxymethamphetamine (MDMA). Most ...clinical MDMA research in patients to date has focused on MDMA-assisted psychotherapy to treat posttraumatic stress disorder (PTSD). In this review paper other potential therapeutic applications for MDMA therapy are described, including contemporary studies treating anxiety associated with autism and the authors' ongoing study exploring the potential role for MDMA-assisted psychotherapy to treat alcohol use disorder. MDMA therapy for PTSD is now entering the final Phase 3 stage of drug development, with a target set for licensing by the FDA and EMA in 2021. This means that if clinical efficacy criteria are achieved, MDMA would become a medicine.
Background:
Posttraumatic stress disorder often does not resolve after conventional psychotherapies or pharmacotherapies. Pilot studies have reported that 3,4-methylenedioxymethamphetamine (MDMA) ...combined with psychotherapy reduces posttraumatic stress disorder symptoms.
Aims:
This pilot dose response trial assessed efficacy and safety of MDMA-assisted psychotherapy across multiple therapy teams.
Methods:
Twenty-eight people with chronic posttraumatic stress disorder were randomized in a double-blind dose response comparison of two active doses (100 and 125 mg) with a low dose (40 mg) of MDMA administered during eight-hour psychotherapy sessions. Change in the Clinician-Administered PTSD Scale total scores one month after two sessions of MDMA served as the primary outcome. Active dose groups had one additional open-label session; the low dose group crossed over for three open-label active dose sessions. A 12-month follow-up assessment occurred after the final MDMA session.
Results:
In the intent-to-treat set, the active groups had the largest reduction in Clinician-Administered PTSD Scale total scores at the primary endpoint, with mean (standard deviation) changes of −26.3 (29.5) for 125 mg, −24.4 (24.2) for 100 mg, and −11.5 (21.2) for 40 mg, though statistical significance was reached only in the per protocol set (p=0.03). Posttraumatic stress disorder symptoms remained lower than baseline at 12-month follow-up (p<0.001) with 76% (n=25) not meeting posttraumatic stress disorder criteria. There were no drug-related serious adverse events, and the treatment was well-tolerated.
Conclusions:
Our findings support previous investigations of MDMA-assisted psychotherapy as an innovative, efficacious treatment for posttraumatic stress disorder.
Psychedelic Harm Reduction and Integration (PHRI) is a transtheoretical and transdiagnostic clinical approach to working with patients who are using or considering using psychedelics in any context. ...The ongoing discussion of psychedelics in academic research and mainstream media, coupled with recent law enforcement deprioritization of psychedelics and compassionate use approvals for psychedelic-assisted therapy, make this model exceedingly timely. Given the prevalence of psychedelic use, the therapeutic potential of psychedelics, and the unique cultural and historical context in which psychedelics are placed, it is important that mental health providers have an understanding of the unique motivations, experiences, and needs of people who use them. PHRI incorporates elements of harm reduction psychotherapy and psychedelic-assisted psychotherapy, and can be applied in both brief and ongoing psychotherapy interactions. PHRI represents a shift away from assessment limited to untoward outcomes of psychedelic use and abstinence-based addiction treatment paradigms and toward a stance of compassionate, destigmatizing acceptance of patients' choices. Considerations for assessment, preparation, and working with difficult experiences are presented.
Eating disorders (EDs) and posttraumatic stress disorder (PTSD) are highly comorbid, yet there are no proven integrative treatment modalities for ED-PTSD. In clinical trials, MDMA-assisted therapy ...(MDMA-AT) has shown marked success in the treatment of PTSD and may be promising for ED-PTSD.
Ninety individuals with severe PTSD received treatment in a double-blind, placebo-controlled pivotal trial of MDMA-AT. In addition to the primary (Clinician-Administered PTSD Scale) and secondary (Sheehan Disability Scale) outcome measures, the Eating Attitudes Test 26 (EAT-26) was administered for pre-specified exploratory purposes at baseline and at study termination.
The study sample consisted of 58 females (placebo = 31, MDMA = 27) and 31 males (placebo = 12, MDMA = 19) (n = 89). Seven participants discontinued prior to study termination. At baseline, 13 (15%) of the 89 individuals with PTSD had total EAT-26 scores in the clinical range (≥20), and 28 (31.5%) had total EAT-26 scores in the high-risk range (≥11) despite the absence of active purging or low weight. In completers (n = 82), there was a significant reduction in total EAT-26 scores in the total group of PTSD participants following MDMA-AT versus placebo (p = .03). There were also significant reductions in total EAT-26 scores in women with high EAT-26 scores ≥11 and ≥ 20 following MDMA-AT versus placebo (p = .0012 and p = .0478, respectively).
ED psychopathology is common in individuals with PTSD even in the absence of EDs with active purging and low weight. MDMA-AT significantly reduced ED symptoms compared to therapy with placebo among participants with severe PTSD. MDMA-AT for ED-PTSD appears promising and requires further study.
3,4-methylenedioxymethamphetamine (MDMA) is a popular recreational drug, however over 200 studies demonstrate that acute (e.g. hyperthermia, rhabdomyolysis) and chronic (e.g. neurotoxicity) toxicity ...effects of MDMA were observed in different animals. Methimazole (MMI), an inhibitor of thyroid hormone synthesis, was found to significantly reduce the HSP72 expression of heat stress induced in fibroblasts. Hence, we attempted to understand the effects of MMI on MDMA induced changes in vivo. Male SD rats were randomly divided into four groups as follows:(a) water-saline (b) water-MDMA (c) MMI-saline and (d) MMI-MDMA group. In the temperature analysis test, MMI was found to alleviate MDMA-induced hyperthermia and increase the heat loss index (HLI), revealing its peripheral vasodilation effect. PET experiment suggested that MDMA induced elevated glucose uptake by skeletal muscles, which was resolved by MMI pretreatment. IHC staining (serotonin transporter, SERT) showed the evidence of neurotoxicity caused by MDMA (serotonin fiber loss), which was alleviated by MMI. Furthermore, the animal behaviour test (forced swimming test, FST) showed higher swimming time but lower immobility time in MMI-MDMA and MMI-saline groups. Taken together, treatment of MMI shows benefits such as lowered body temperature, alleviation of neurotoxicity and excited behaviour. However, further investigations should be conducted in the future to provide in-depth evidence for its clinical use.
