Long-Term Safety and Effectiveness of MDMA-Assisted Therapy for PTSD (MPLONG)
January 22, 2024 updated by: Lykos Therapeutics
Long-Term Safety and Persistence of Effectiveness of Manualized MDMA-Assisted Therapy for the Treatment of Posttraumatic Stress Disorder
Data from a series of Phase 2 and 3 studies of MDMA-assisted therapy conducted by the sponsor provide preliminary evidence that chronic Posttraumatic Stress Disorder (PTSD), independent of cause, is treatable with up to three sessions of MDMA-assisted therapy.
This non-interventional study will serve as the long-term follow-up (LTFU) protocol for MDMA-assisted therapy clinical trials and will measure persistence of effectiveness using the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) as a measure of PTSD symptom severity.
Additionally, this study will gather data to support health economics and cost effectiveness analyses of this treatment.
Participants who have received at least one dose of Investigational Medicinal Product (IMP) in the main study will be eligible to participate in this study.

Detailed Description
The Multidisciplinary Association for Psychedelic Studies (MAPS) is a non-profit research and education organization working as a clinical trial sponsor to obtain approval for the prescription use of 3,4-methylenedioxymethamphetamine (MDMA) as an adjunct to therapy for treatment of posttraumatic stress disorder (PTSD).
Data from a series of Phase 2 and 3 studies of MDMA-assisted therapy conducted by the sponsor provide preliminary evidence that chronic PTSD, independent of cause, is treatable with up to three sessions of MDMA-assisted therapy.
This non-interventional study will serve as the long-term follow-up (LTFU) protocol for MDMA-assisted therapy clinical trials and will measure persistence of effectiveness using the CAPS-5 as a measure of PTSD symptom severity.
The primary objective of this study is to evaluate the long-term effectiveness of MDMA-assisted therapy for treatment of PTSD as measured by the change in CAPS-5 Total Severity Score (actual or imputed) from the main study Baseline and Study Termination to LTFU IR Assessments (Visit 1).
Additionally, this study will gather data to support health economics and cost effectiveness analyses of this treatment.
Participants who have received at least one dose of Investigational Medicinal Product (IMP) in the main study will be eligible to participate in this study.

Measure Description |
Time Frame |
---|---|---|
Clinician Administered PTSD Scale for DSM-V (CAPS-5) Total Severity Score (actual or imputed) from the main study Baseline and Study Termination to assessment in the current LTFU study
Time Frame: LTFU IR Assessments at Least 6 Months Since Last Experimental Session in Main Study (Visit 1)
|
The Clinician-Administered PTSD Scale for DSM-V (CAPS-5) is a clinician administered and scored assessment of PTSD symptoms via structured interview based upon PTSD diagnosis in DSM-5.
The total severity score is a sum of symptom frequency and intensity scores for the subscales B (re-experiencing), C (avoidance) and D (hypervigilance) and ranges from 0 to 136, with higher scores indicating greater severity of PTSD symptoms.
