| Trial Success | Single 30mg dose achieved 23.0 point reduction in depression scores versus 17.2 points in control group |
| Drug Type | Prodrug of 4-OH-DiPT, similar to psilocin from “magic mushrooms” |
| Duration | Psychedelic experience lasts 3 to 4 hours, half the time of psilocybin |
| Safety Profile | 92.7% of patients ready for discharge within four hours |
| Next Steps | Phase 3 trial planned to begin in 2026 |
Revolutionary Treatment Approach
RE104 stands apart from traditional antidepressants by offering rapid relief through a single injection. The drug is a prodrug converting to 4-OH-DiPT, offering psilocybin-like effects with a shorter duration, potentially reducing healthcare resource demands. This breakthrough addresses a critical gap in postpartum depression treatment, where mothers need effective solutions that don’t interfere with their ability to care for their newborns.
The RECONNECT trial enrolled 84 women across 38 US sites, comparing a therapeutic 30mg dose against a 1.5mg control dose. The trial met its primary endpoint with statistical significance in reducing depression symptoms measured by the Montgomery-Åsberg Depression Rating Scale.

Safety and Practical Benefits
Safety concerns often limit treatment options for new mothers, especially those who breastfeed. Preliminary results from a lactation study suggest that the total amount of metabolites observed in breastmilk represents less than 0.1% of the 30mg dose administered. This finding could allow mothers to resume breastfeeding with minimal interruption.
The drug’s short duration offers practical advantages over other psychedelic treatments. There was no evidence of treatment-emergent seizures or serotonin toxicity, and no clinically significant electrocardiogram findings. Nearly all patients were ready for discharge within hours, distinguishing RE104 from longer-acting psychedelic therapies that require extended medical supervision.
Addressing Unmet Medical Needs
Postpartum depression affects approximately 10 to 15 percent of new mothers, yet current treatments often fall short. Women suffering from PPD often experience significant changes in mood, appetite and sleep contributing to feelings of hopelessness, lack of concentration, loss of energy, poor self-esteem. Traditional antidepressants can take weeks to show effects and may interfere with breastfeeding.
Current PPD treatments, including SSRIs and GABA-A modulators, have limitations, highlighting the need for new, effective therapies. RE104’s rapid onset and single-dose administration could transform how physicians approach this debilitating condition.
Path Forward
The success of the Phase 2 trial positions RE104 for regulatory advancement. Company plans to initiate pivotal Phase 3 trial of RE104 in PPD in 2026. Reunion Neuroscience is also exploring the drug’s potential in treating adjustment disorder, expanding its therapeutic applications beyond postpartum depression.
The company’s approach reflects broader interest in psychedelic medicine for mental health conditions. Reunion Neuroscience is a clinical stage pharmaceutical company developing therapeutic solutions for underserved mental health conditions. If successful in Phase 3 trials, RE104 could become the first psychedelic-based treatment specifically approved for postpartum depression, offering hope to millions of mothers worldwide.
