As <a href="https://www.globenewswire.com/Tracker?data=ZhUR7I1paMgz4ufTiCgO0ev1XHEIqOexdNRPVghNxd8t0QJDxWeKepZ7wFd5vmajWrhVMNxhgp5SPgpsLj87bO5PJcboa2H4Anrn7tNstI5iJYwDySb8fnak1kHCnwZrM-f5xU90a4NC3agb6WN2LwjI5QsCMIJohgRttSUU0FLRHVu-69MCjBfUQJFpIlSlfFBfPoQMeUbdAon1-M74FDUqzxAQOPJsSQXOtdmMNOXAk9q4I_8tFhr7yoPdZBkUmfNS9zdzE0z5wV5790FH5h8CsZX79flKhP7BoXclWSFcGBIKufws5SdRpKXQLOF0" rel="nofollow" target="_blank" title="previously presented">previously presented</a> in a poster session at the American College of Neuropsychopharmacology (ACNP) Annual Meeting, RECONNECT met its primary endpoint, with a statistically significant and clinically meaningful reduction in depression as measured by the MADRS total score observed on Day 7. Clinically meaningful reductions in MADRS were observed for luvesilocin 30mg-treated patients on the first day following administration and maintained through the 28-day follow-up. Substantial and clinically meaningful improvements in other key secondary endpoints, including MADRS response and remission rates and other measures of PPD-related symptoms, were also observed. Based on these data, Reunion Neuroscience aligned with the U.S. Food and Drug Administration (FDA) on a registrational path for luvesilocin in PPD. The Company expects to advance luvesilocin into a pivotal Phase 3 trial in 2026. Based on feedback from the FDA, Reunion expects that the results from this single Phase 3 trial, if successful, would complete the data package required to support potential registration of luvesilocin in PPD. Details of the ASCP presentation are as follows: Title: RE104: A Novel Serotonergic Psychedelic 4-OH-DiPT Prodrug for the Treatment of Postpartum Depression  Session: Pharmaceutical Pipeline Session Session Date and Time: Tuesday, May 26, 2026 from 2:00 – 4:00 PM ET Presentation Time: Tuesday, May 26, 2026 from 2:00 – 2:10 PM ET Presenter: Mark Pollack, M.D., Chief Medical Officer, Reunion Neuroscience Reunion Neuroscience will also present data in a poster session entitled, “RE104: A Novel Psychedelic Agent for Postpartum Depression,” at the 2026 American Psychiatric Association (APA) Annual Meeting, May 18, 2026 in San Francisco, CA. About Luvesilocin Luvesilocin is a proprietary, potential best-in-class, patented prodrug of 4-OH-DiPT, which is administered via a subcutaneous injection. Reunion designed luvesilocin to deliver rapid efficacy with a short psychoactive experience, making luvesilocin more convenient than the longer experience and monitoring required with psychedelics like psilocybin or LSD. Reunion is evaluating luvesilocin as a subcutaneous administration for the treatment of mood and anxiety disorders, including PPD, adjustment disorder (AjD), generalized anxiety disorder (GAD) and other potential indications. Following positive data from the Phase 2 RECONNECT trial, the U.S. Food and Drug Administration granted luvesilocin Breakthrough Therapy Designation in PPD. Reunion expects to initiate a pivotal Phase 3 clinical trial in PPD in 2026, which, if successful, could support potential registration of luvesilocin. Additionally, Reunion is enrolling patients in the Phase 2 REKINDLE (<a href="https://www.globenewswire.com/Tracker?data=LRpJ2gUDcyIzlXou2Y2VTsifE8u_xd163KMj5pgU3OpKWPeySQ3ib4abw1-E36Qykmcc2-mpK5AMInLlfWwoQcYjtgr92J4e-WDwd9Ln_w0X_BopcyXIpY8S6_qRMTHYnJ00AikXpW9qEfs_Q2KNcw==" rel="nofollow" target="_blank" title="NCT07002034">NCT07002034</a>) clinical trial in patients with AjD related to cancer and other medical illnesses and the Phase 2 RECLAIM (<a href="https://www.globenewswire.com/Tracker?data=LRpJ2gUDcyIzlXou2Y2VTp0dBZWp4dVnI4d6kljUHvdFeMZ_h1hrF3mivBsnf2n58aA2Qrjga1iJRgE_nwTsuIW3WAxYuObL7PGDaL7rVfIdf5nwWMdsW7-4JvF-PmDa" rel="nofollow" target="_blank" title="NCT07489651">NCT07489651</a>) clinical trial in patients with GAD.
