The initial application from Lykos presented positive data from two late-stage clinical trials that used MDMA in combination with talk therapy to treat PTSD. The advisers said it was also difficult to parse how much the accompanying talk therapy — an area that the FDA does not regulate — contributed to outcomes. Advocates for the treatment, including some veterans groups, said they were “incredibly disappointed” by the FDA decision. Dozens of clinical trials involving psychedelics are in various stages, and additional scrutiny can help strengthen the findings and build confidence. Psychopharmacology did not allow the study authors to publish a correction with data that excluded findings from one study site, said Allison Feduccia, an author in all three retracted studies.
