What Happened

Definium Therapeutics announced positive topline results from its Phase 3 Panorama study of DT120 ODT, an oral synthetic lysergic acid diethylamide (LSD) derivative, for the treatment of generalized anxiety disorder. The trial met its primary and key secondary endpoints, reinforcing the drug’s potential as a treatment for anxiety. The results were disclosed in a Form 8-K filed with the SEC on September 14, 2026, and were also highlighted in multiple reports across the financial wire. The Fly and Reuters both confirmed the success of the trial, with Reuters noting that the drug lowered anxiety symptoms in a second successful late-stage study. The news comes after the company previously received FDA Breakthrough Therapy Designation for DT120 ODT.

The stock opened at $45.56, reflecting a 17.2% gap from the prior close of $38.89. It reached an intraday high of $47.50 at 7:30 AM ET but declined throughout the session, closing at $42.11. The volume of 1.2 million shares was 0.5 times the 3-month daily average, indicating moderate institutional and retail participation. Over the past 8 sessions, the stock has risen 11.2% from $38.90 to $43.24. The 52-week range is $8.77 to $49.70, and the stock printed one fresh 52-week high and three fresh 52-week lows on September 14. Insider transactions over the last 90 days include six sales totaling $3.3 million, with no insider purchases reported.
