Shares of Psyence Biomedical (PBM) surged over 111% to top premarket gains across U.S. stocks on Monday after U.S. President Donald Trump’s executive order accelerating psychedelic therapy research spotlighted the supply infrastructure behind post-traumatic stress disorder (PTSD) treatments such as ibogaine.
PBM stock surged 185% last week, marking its strongest weekly performance in more than two years.
Over the weekend, Trump signed an executive order directing the U.S. Food and Drug Administration (FDA) to expedite the review of psychedelic medicines including ibogaine, while committing $50 million in federal funding toward related clinical research programs.
Speaking at the Oval Office signing ceremony, Trump said emerging psychedelic treatments could have a “tremendous impact” if supported by clinical evidence and highlighted their potential role in addressing serious mental-health conditions affecting veterans.
Ibogaine, derived from a shrub native to Central and West Africa, remains classified as a Schedule I substance in the U.S. despite growing interest from veterans’ advocacy groups studying its potential use in treating PTSD.
A day before the executive order was signed, Psyence CEO Jody Aufrichtig said, “Ibogaine has emerged as a compound of increasing global interest, particularly for its potential to address complex and treatment-resistant conditions.” He added that expanding regulated clinical research would be essential to improving both patient safety and long-term access to ibogaine-based treatments.
Through its investment in PsyLabs, the company has built a Good Manufacturing Practice (GMP)-compliant platform that produces pharma-grade psychedelic compounds, including ibogaine, for use in clinical research and drug-development programs.
In January, the company said it produced high-purity ibogaine hydrochloride, a medical-grade form of the compound, from ethically sourced natural supply in Africa. The company had already secured access to high-potency iboga bark and established ibogaine operations in Africa through PsyLabs.
Separately, last month, the company exported GMP-compliant psilocybin product NPX-5 to Australia for use in an ongoing Phase IIb clinical trial evaluating treatment for adjustment disorder in patients with cancer receiving palliative care.
On Stocktwits, retail sentiment for PBM has been ‘extremely bullish’ for a week amid a whopping 15,100% surge in message volumes over the past month.
