Overview of the Phase 3 Emerge Trial
On 22 June 2026, Definium Therapeutics Inc. (Nasdaq: DFTX) announced the completion of its Phase 3 Emerge study for the investigational oral‑disintegrating tablet DT120. The study enrolled adults with major depressive disorder (MDD) and evaluated a single dose of DT120 versus placebo. Key findings reported by the company and corroborated by independent media sources include:
- Primary endpoint achieved: DT120 produced an 8.1‑point placebo‑adjusted improvement on the Montgomery‑Åsberg Depression Rating Scale (MADRS) at Week 6.
- Rapid onset of benefit: Significant improvement was observed as early as Week 1.
- Durable effect: Benefits were sustained for several weeks following the single dose.
- Safety profile: No unexpected adverse events were reported; the safety profile was described as clean.
These data are described in multiple news outlets (Nasdaq.com, RTTNews, CoinCentral, TipRanks, Bloomberg, Investor’s Business Daily, and others) and are considered a breakthrough result for a psychedelic‑derived antidepressant.
