About

This randomized, double-blind, single-site phase II 2-arm study will investigate the safety and preliminary efficacy of MDMA-assisted therapy compared with low dose d-amphetamine-assisted therapy on the severity of PTSD symptoms in participants aged 18 years and older with PTSD of at least moderate severity.

Full description

This randomized, double-blind, single-site phase II 2-arm study will compare MDMA-assisted therapy with low dose d-amphetamine-assisted therapy to treat PTSD symptoms in veteran participants aged 18 years and older with PTSD of at least moderate severity, as measured by the change in CAPS-5 total severity score. The study will be conducted in up to N=40 participants from the Greater Los Angeles VA randomized with a 1:1 allocation to Group 1: MDMA-assisted therapy or Group 2: low dose d-amphetamine assisted therapy.

For each participant, the study will consist of:

• Screening Period: phone screen, informed consent, eligibility assessment, Screening CAPS-5, and Initial Enrollment of eligible participants.
• Preparatory Period: medication tapering, three Preparatory Sessions, baseline assessments (including Baseline CAPS-5), leading to Enrollment Confirmation.
• Treatment Period: three Experimental Sessions, and three Integrative Sessions following each Experimental Session including CAPS-5 assessments.
• Follow-up Period and Study Termination: Primary Outcome CAPS-5 assessment and Study Termination visit.

Enrollment: 40 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• At Screening, meet DSM-5 criteria for current PTSD with a symptom duration of at least 6 months.

• Able to identify appropriate support person(s) to stay with the participant on the evenings of Experimental Sessions if needed.
