Investigator-Initiated Trials (IIT)

Investigator-initiated trials (IIT) are unique clinical trials sponsored and implemented by clinicians to further investigate a specific research question within their field. 

The MAPS Public Benefit Corporation (MAPS PBC) investigator-initiated trial (IIT) program is designed to create a network of clinicians whose innovative questioning helps to expand patient access for investigational conditions that MDMA-assisted therapy may assist in treating. The U.S. Food and Drug Administration (FDA) defines an investigator as “an individual who both initiates and conducts a clinical trial, and under whose immediate direction the investigational drug is administered.” The clinician has the responsibility to comply with federal regulations applicable to both the sponsor and the investigator.
