Major strides for the company on two fronts – psychedelic therapies and treatment-resistant depression (TRD) – came in the form of Dublin-based GH Research plc’s phase IIb data with GH-001, an inhalable mebufotenin (5-MeO-DMT) activator of serotonin 5-HT2A and 5-HT1A receptors that met not only its primary endpoint but all secondary goals in the TRD experiment. Shares of GH (NASDAQ:GHRS) closed Feb. 3 at $17.99, up $7.39, or 69.7%, on word that the fast-acting, short-duration compound led to a significant reduction from baseline of -15.2 points in Montgomery-Åsberg Depression Rating Scale total score on the eighth day of treatment compared with +0.3 points in the placebo group (a difference of -15.5 points, p<0.0001).
Psychedelic drugs may exert their effects at intracellular serotonin receptors that serotonin itself, which does not cross cell membranes, cannot reach. The findings were published in the Feb. 17, 2023, issue of Science by researchers from the University of California at Davis.
Psychedelic drugs may exert their effects at intracellular serotonin receptors that serotonin itself, which does not cross cell membranes, cannot reach. The findings were published in the Feb. 17, 2023, issue of Science by researchers from the University of California at Davis. An accompanying editorial by Evan Hess and Todd Gould at the University of Maryland School of Medicine called them “a key achievement in the understanding of the mechanism of action of psychedelics” and “an important step forward for a rapidly expanding and much-needed field of study.”
The burgeoning psychedelic therapeutics market experienced a boost Jan. 25 as Small Pharma Inc. announced its synthetic, intravenous formulation of N,N-dimethyltryptamine (DMT), SPL-026, led to a statistically significantly, rapid reduction in depression symptoms in patients with major depressive disorder in a phase IIa trial, thus meeting its primary endpoint. DMT is a powerful hallucinogenic tryptamine substance which works as a 5-HT receptor agonist. It is found naturally in various plants, and is a schedule I controlled substance in the U.S. Although lesser known than other psychedelics such as magic mushrooms and LSD, it produces short-lived but intense auditory and visual hallucinogenic effects.
Not long ago, people who touted the prospects of psychedelic drugs might have been accused of hallucinating, but in the U.S. and elsewhere the space has expanded in recent years, as mental health treatments remain “stuck where cancer was 50 years ago,” said Roth analyst Elemer Piros.
