Lykos Therapeutics Announces FDA Advisory Committee Meeting to Review Investigational MDMA-Assisted Therapy for PTSD
  • Meeting to be held on June 4, 2024
  • First FDA Advisory Committee meeting for potential new PTSD treatment in 25 years

SAN JOSE, Calif., May 6, 2024 /PRNewswire/ -- Lykos Therapeutics (formerly MAPS Public Benefit Corporation) ("Lykos"), a company dedicated to transforming mental healthcare, announced that on June 4, 2024, the U.S. Food and Drug Administration's ("FDA") Psychopharmacologic Drugs Advisory Committee ("PDAC") will review data supporting the new drug application ("NDA") for midomafetamine (MDMA) capsules used in combination with psychological intervention ("MDMA-assisted therapy") for adults with post-traumatic stress disorder ("PTSD"). This will be the first FDA advisory committee meeting to review a potential new PTSD treatment in 25 years.1 As with all advisory committee meetings, there will be an open public hearing (OPH) session, during which interested persons may present relevant information or views orally or in writing.

"This will be the first MDMA-assisted therapy and psychedelic-assisted therapy to be reviewed by the Psychopharmacologic Drugs Advisory Committee, a significant milestone in the field of psychedelic medicine, resulting from decades of clinical research and advocacy," said Amy Emerson, Chief Executive Officer of Lykos Therapeutics. "We look forward to the opportunity to discuss the comprehensive data package of investigational MDMA and how, if approved, it may be used as a prescription treatment in combination with psychological intervention in adults with PTSD."

PDAC will review results from numerous studies including two randomized, double-blind, placebo-controlled Phase 3 studies (MAPP1 and MAPP2) evaluating the efficacy and safety of MDMA used in combination with psychological intervention, which includes psychotherapy (talk therapy) and other supportive services provided by a qualified healthcare provider, versus placebo with psychological intervention in participants diagnosed with severe or moderate to severe PTSD, respectively. Both MAPP1 and MAPP2 studies met their primary and secondary endpoints and were published in Nature Medicine.2,3

On February 9, 2024, the FDA accepted the company's NDA for midomafetamine used in combination with psychological intervention for adults with PTSD. The FDA granted the application Priority Review and has assigned a Prescription Drug User Fee Act ("PDUFA") target action date of August 11, 2024. The FDA grants Priority Review for drugs that, if approved, would represent significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications.4 If approved, this would be the first MDMA-assisted therapy and psychedelic-assisted therapy. 

Midomafetamine (MDMA) capsules have not been approved by any regulatory agency. The safety and efficacy of midomafetamine have not been established for the treatment of PTSD. Investigational midomafetamine is also being studied in other indications.
