Diamond Therapeutics contracts BioPharma Services for Phase 1 clinical trial

TORONTO, June 17, 2021 /PRNewswire/ - Diamond Therapeutics Inc. ("Diamond"), a leading drug development company focused on low-dose psychedelic therapies for mental health, is pleased to announce the selection of BioPharma Services Inc. ("BioPharma"), as the contract research organization (CRO) for its Phase 1 clinical trial.

The proposed study, titled "A Randomized, Double-Blind, Single Ascending Dose Study to Identify a Safe and Non-Psychedelic Dose of Psilocybin," will evaluate low doses of psilocybin in healthy volunteers.

The agreement with BioPharma is a key step towards initiating this trial.

"The trial we are proposing will systematically explore the effects of psilocybin over a range of very low doses. To our knowledge, a single ascending dose study in this dose range has never been conducted," said Judy Blumstock, CEO of Diamond.

Led by an expert panel of experienced physicians and research scientists, BioPharma has a track record of delivering research excellence in early-stage clinical studies.

BioPharma's Dr. Isabella Szeto will serve as principal investigator on the trial. Dr. Szeto has more than 15 years of experience conducting Phase 1 clinical research with a focus on CNS drug candidates, including abuse liability trials, to meet current FDA requirements.

"BioPharma is excited to be involved in this trial that has potential, in the long term, to provide needed therapeutics for the population of patients living with mental health disorders," said Dr. Szeto.

Diamond's preclinical research demonstrated, for the first time, that certain, very low, non-hallucinogenic doses of psilocybin have beneficial properties and hold potential for therapeutic use. Diamond believes these findings provide validation for the use of non-hallucinogenic doses of psilocybin in treating psychiatric disorders, including anxiety and depression.

The acceptability of the proposed study will be assessed during Health Canada's formal review of Diamond's clinical trial application.
