Abstract

The success of modern medicine creates a growing population of those suffering from life-threatening illnesses (LTI) who often experience anxiety, depression, and existential distress. We present a novel approach; investigating MDMA-assisted psychotherapy for the treatment of anxiety in people with an LTI. Participants with anxiety from an LTI were randomized in a double-blind study to receive MDMA (125 mg, n = 13) or placebo (n = 5) in combination with two 8-h psychotherapy sessions. The primary outcome was change in State-Trait Anxiety Inventory (STAI) Trait scores from baseline to one month post the second experimental session. After unblinding, participants in the MDMA group had one open-label MDMA session and placebo participants crossed over to receive three open-label MDMA sessions. Additional follow-up assessments occurred six and twelve months after a participant’s last experimental session. At the primary endpoint, the MDMA group had a greater mean (SD) reduction in STAI-Trait scores, – 23.5 (13.2), indicating less anxiety, compared to placebo group, – 8.8 (14.7); results did not reach a significant group difference (p = .056). Hedges’ g between-group effect size was 1.03 (95% CI: – 5.25, 7.31). Overall, MDMA was well-tolerated in this sample. These preliminary findings can inform development of larger clinical trials to further examine MDMA-assisted psychotherapy as a novel approach to treat individuals with LTI-related anxiety.Trial Registration: clinicaltrials.gov Identifier: NCT02427568, first registered April 28, 2015.

Long-term follow-up outcomes of MDMA-assisted psychotherapy for treatment of PTSD: a longitudinal pooled analysis of six phase 2 trials

January 3, 2022 / Anxiety Disorders / PTSD, MDMA, Papers / Leave a Comment / By / , , , , , , ,

Abstract

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.

Posttraumatic Growth After MDMA-Assisted Psychotherapy for Posttraumatic Stress Disorder

March 14, 2022 / Anxiety Disorders / PTSD, MDMA, Papers / Leave a Comment / By / , , , , , , , ,

Abstract

3,4-Methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for posttraumatic stress disorder (PTSD) has been shown to significantly reduce clinical symptomatology, but posttraumatic growth (PTG), which consists of positive changes in self-perception, interpersonal relationships, or philosophy of life, has not been studied with this treatment. Participant data (n = 60) were pooled from three Phase 2 clinical studies employing triple-blind crossover designs. Participants were required to meet DSM-IV-R criteria for PTSD with a score higher than 50 on the Clinician-Administered PTSD Scale (CAPS-IV) as well as previous inadequate response to pharmacological and/or psychotherapeutic treatment. Data were aggregated into two groups: an active MDMA dose group (75-125 mg of MDMA; n = 45) or placebo/active control (0-40 mg of MDMA; n = 15). Measures included the Posttraumatic Growth Inventory (PTGI) and the CAPS-IV, which were administered at baseline, primary endpoint, treatment exit, and 12-month follow-up. At primary endpoint, the MDMA group demonstrated more PTG, Hedges’ g = 1.14, 95% CI [0.49, 1.78], p < .001; and a larger reduction in PTSD symptom severity, Hedges’ g = 0.88, 95% CI [-0.28, 1.50], p < .001, relative to the control group. Relative to baseline, at the 12-month follow-up, within-subject PTG was higher, p < .001; PTSD symptom severity scores were lower, p < .001; and two-thirds of participants (67.2%) no longer met criteria for PTSD. MDMA-assisted psychotherapy for PTSD resulted in PTG and clinical symptom reductions of large-magnitude effect sizes. Results suggest that PTG may provide a new mechanism of action warranting further study.

Abstract

3,4‐Methylenedioxymethamphetamine (MDMA)–assisted psychotherapy for posttraumatic stress disorder (PTSD) has been shown to significantly reduce clinical symptomatology, but posttraumatic growth (PTG), which consists of positive changes in self‐perception, interpersonal relationships, or philosophy of life, has not been studied with this treatment. Participant data (n = 60) were pooled from three Phase 2 clinical studies employing triple‐blind crossover designs. Participants were required to meet DSM‐IV‐R criteria for PTSD with a score higher than 50 on the Clinician‐Administered PTSD Scale (CAPS‐IV) as well as previous inadequate response to pharmacological and/or psychotherapeutic treatment. Data were aggregated into two groups: an active MDMA dose group (75–125 mg of MDMA; n = 45) or placebo/active control (0–40 mg of MDMA; n = 15). Measures included the Posttraumatic Growth Inventory (PTGI) and the CAPS‐IV, which were administered at baseline, primary endpoint, treatment exit, and 12‐month follow‐up. At primary endpoint, the MDMA group demonstrated more PTG, Hedges’ g = 1.14, 95% CI [0.49, 1.78], p < .001; and a larger reduction in PTSD symptom severity, Hedges’ g = 0.88, 95% CI [−0.28, 1.50], p < .001, relative to the control group. Relative to baseline, at the 12‐month follow‐up, within‐subject PTG was higher, p < .001; PTSD symptom severity scores were lower, p < .001; and two‐thirds of participants (67.2%) no longer met criteria for PTSD. MDMA‐assisted psychotherapy for PTSD resulted in PTG and clinical symptom reductions of large‐magnitude effect sizes. Results suggest that PTG may provide a new mechanism of action warranting further study.
