The FDA has rejected Lykos Therapeutics' application for MDMA-assisted therapy for post-traumatic stress disorder. The FDA requested that Lykos conduct another Phase III trial to study the safety and efficacy of MDMA further.
Lykos Therapeutics plans to request a meeting with the FDA to discuss the decision and explore regulatory pathways. The company believes existing data can address many of the FDA's concerns and is committed to finding an expeditious path forward for patients.
Analyst QuickTake: The rejection reflects concerns raised during the FDA advisory committee meeting in June 2024 , including issues related to the durability of the treatment's effects, potential expectancy bias from participants with prior MDMA use, and questions about the role of psychotherapy in the treatment.
