Diamond Therapeutics Announces Health Canada Approval of Clinical Trial with Low-Dose Psilocybin

TORONTO, Aug. 17, 2021 /CNW/ – Diamond Therapeutics Inc. (“Diamond”), a drug development company focused on low-dose psychedelic therapies for use in the treatment of mental health, is pleased to announce that it has received a No Objection Letter from Health Canada, allowing Diamond to proceed with a human clinical trial to evaluate low doses of psilocybin in healthy volunteers.

The trial is a Phase 1 randomized, placebo-controlled, double-blind study to evaluate the safety and pharmacokinetics of low doses of psilocybin in as many as 80 study participants.

According to Health Canada’s clinical trials database, to date, there are only two other Canadian clinical trials involving psilocybin.

“We are grateful to Health Canada for their support of this groundbreaking study,” says Judy Blumstock, CEO of Diamond. 

The study will build on the results of previous animal research conducted by Diamond that demonstrated for the first time that certain, low, non-hallucinogenic doses of psilocybin hold potential for therapeutic use. Diamond believes these findings may help unlock the use of low-dose psilocybin to treat psychiatric disorders, including anxiety and depression. 

“This upcoming clinical trial will enable Diamond to gain critical clinical information that will help inform future human trials with psilocybin and other pipeline compounds,” says Dr. Edward Sellers, chair of Diamond’s scientific advisory board.

Diamond is also planning to launch a Phase 2 trial to investigate low-dose psilocybin’s efficacy in treating anxiety, which is the most common mental health disorder in the U.S., causing moderate to severe disability in over 50% of sufferers. This Phase 2 study will be conducted in both Canada and the U.S.

As well, Diamond plans to support an investigator-led study of low-dose psilocybin in the U.S. to explore its effects on patients with moderate depression.

“We’re very excited to commence our clinical program. It brings us one step closer to creating therapeutics that can help more people access effective and safe treatments for mental health conditions,” says Ms. Blumstock.

“It’s because of the hard work of our team, partners and advisors that we’ve been able to achieve this significant milestone,” she says.

The safety and efficacy of psilocybin for any indication has not yet been established.
