March 15, 2023

The clinical trial will study PEX010, Filament’s botanical psilocybin drug candidate

 Vancouver, British Columbia, March 15, 2023 – Filament Health Corp. (OTCQB:FLHLF) (NEO:FH) (FSE:7QS) (“Filament”or the “Company”), a clinical‐stage natural psychedelic drug development company, today announced approval from the United States Food and Drug Administration (FDA) for a clinical trial at the University ofCalifornia San Francisco’s Translational Psychedelic Research Program (TrPR).The investigator initiated trial will study the effects of PEX010, Filament’s botanical psilocybin drug candidate, for the treatment of methamphetamine use disorder (MAUD).

MAUD is a growing public health emergency that is associated with serious health consequences. In the United States, the prevalence and mortality of MAUD has doubled over the past decade, yet available treatments have limited efficacy. Psilocybin offers a possible breakthrough – a single dose has been found to dramatically increase abstinence and reduce consumption in individuals with substance use disorders. The goal of this trial will be to determine the safety, tolerability, and feasibility of psilocybin therapy for people living with MAUD.

“We’re pleased to support this much-needed research,” said Benjamin Lightburn, Chief Executive Officer and Co-Founder ofFilament Health. “This trial is the first time that naturally-derived, non-synthetic psilocybin will be studied for methamphetamine use disorder, and represents an important step for Filament into the treatment of substance use disorders.”
