Also known as: S-ketamine
Esketamine is the S-enantiomer of ketamine, marketed as Spravato for depression and Ketanest for anesthesia uses in some regions. It is a dissociative medication used medically as a general anesthetic and as an antidepressant via intranasal administration under supervision for depression. It is a controlled prescription medicine.
Biotech companies announced new financings: HMNC closed a $50M Series B, Cartesian secured a $150M credit facility, Waiv raised $33M, and Brainstorm raised $1M. KET01 showed early efficacy but missed its primary endpoint.
A pooled analysis of five randomized trials found intranasal esketamine improved MADRS scores in adults with TRD in both sexes. Females showed greater improvement and higher odds of treatment-response toward trial end.
Clinical trials show psychedelic substances like psilocybin, LSD and MDMA combined with therapy can effectively treat depression, anxiety and addiction. Several substances are in Phase III trials, with esketamine already approved for treatment-resistant depression. Research suggests these treatments may work with fewer doses than traditional medications.
Compass Pathways announced positive Phase 3 data for COMP360 psilocybin therapy in treatment-resistant depression, showing statistically significant improvements in depression scores and durability through 26 weeks, with plans to file for FDA approval in Q4 2026.
COMPASS Pathways announced positive Phase 3 results for COMP360 psilocybin in treatment-resistant depression, showing statistically significant improvements across two pivotal trials with durability signals through 26 weeks and a generally well-tolerated safety profile.
NRx Pharmaceuticals completed an in-person FDA Type C meeting regarding NRX-100, a preservative-free ketamine formulation for suicidal depression. The company received guidance on a path to file a New Drug Application based on existing trial data and Real World Evidence from over 65,000 patients.
New COMP006 phase 3 data shows single-dose COMP360 psilocybin achieved a 3.8-point MADRS reduction in treatment-resistant depression, with results comparable to esketamine pivotal trials and rapid onset of effect.
Compass Pathways reported COMP360 psilocybin met the primary endpoint in its second phase III trial for treatment-resistant depression, demonstrating a statistically significant reduction in depression severity. The company plans to file a New Drug Application in Q4 2025.
Compass Pathways reports positive Phase 3 results for synthetic psilocybin in treatment-resistant depression, while a Phase 2 trial demonstrates rapid antidepressant effects from single-dose DMT. Both studies show modest efficacy signals amid growing pharmaceutical interest in psychedelic compounds.
Compass Pathways' COMP360 synthetic psilocybin met primary endpoints in Phase 3 trials for treatment-resistant depression, with the company planning to submit a new drug application in Q4 2026.
