Study Endpoints

Primary Endpoints

Change from Baseline on symptoms of Post-Traumatic Stress based on the PTSD Checklist for DSM-5 (PCL-5) at Treatment Termination
Up to 17 weeks post-enrollment (Baseline)

The PCL-5 is a 20-item self-report measure that assesses the 20 DSM-5 symptoms of PTSD and is widely used by researchers and clinicians to monitor change during and after a treatment intervention. Participants indicate how much distress they have experienced due to symptoms such as "Repeated, disturbing memories, thoughts, or images of a stressful experience from the past," "Trouble remembering important parts of a stressful experience from the past," and "Feeling irritable or having angry outbursts" using a Likert scale ranging from 0 (Not at all) to 4 (Extremely). Items are summed to provide a total severity score (range = 0-80). It takes 5-10 minutes to complete.

Secondary Endpoints

Change from Baseline on symptoms of Adjustment Disorder based on the Adjustment Disorder New Module-20 (ADNM-20) at Treatment Termination
Up to 17 weeks post-enrollment (Baseline)

Frequently asked questions about MDMA

What is MDMA used for in Post-Traumatic Stress Disorder?

MDMA is an investigational small molecule being studied for Post-Traumatic Stress Disorder (PTSD). It is in Phase 2 clinical development as MDMA-assisted therapy for stress disorders, including PTSD and adjustment disorders, in healthcare workers and first responders. The drug is not approved and remains under clinical investigation.

What does MDMA target?

MDMA targets the serotonin transporter (SERT). By interacting with SERT, it is thought to modulate serotonin signaling, which may underlie its potential therapeutic effects in Post-Traumatic Stress Disorder. This mechanism is being evaluated in the context of MDMA-assisted therapy for stress-related conditions.

Who is developing MDMA?

MDMA is being developed by Nautilus Biotechnology, Inc., a company traded under the ticker NAUT. The company is conducting clinical research on MDMA-assisted therapy for Post-Traumatic Stress Disorder and related stress conditions in healthcare workers and first responders.

What phase is MDMA in?

MDMA is in Phase 2 clinical development. It is being studied in an ongoing Phase 2 trial for Post-Traumatic Stress Disorder and adjustment disorders. The drug is investigational and has not been approved by regulatory authorities for any use.

What clinical trials is MDMA in?

MDMA is being studied in one Phase 2 clinical trial, identified as NCT05455996, titled "MDMA-Assisted Therapy for Stress Disorders in Healthcare Workers and First Responders." The trial is not yet recruiting and aims to enroll 30 participants in the United States with PTSD or adjustment disorders.
