Recent US executive order named ibogaine compounds among the psychedelic therapies prioritized for accelerated FDA review and expanded patient access

Ibogaine is under investigation to treat PTSD, opioid use disorder and traumatic brain injury

VANCOUVER, BC, June 8, 2026 /CNW/ - via IBN – Optimi Health Corp. (NASDAQ: OPTH) (CSE: OPTI) (FSE: 8BN0) (the "Company" or "Optimi"), a commercial-stage pharmaceutical manufacturer of regulated psychedelic drug products, today provided an update on its recently announced Ibogaine Initiative. Optimi has secured naturally derived ibogaine from two sources, in both hydrochloride (HCl) and freebase form. Development work on the finished drug product is anticipated to commence this summer at the Company's GMP facility in British Columbia, Canada.

"We are seeing a growing number of research institutions interested in ibogaine, and there is real public funding behind it now, including the $50 million program in Texas¹," said Dane Stevens, CEO and Co-Founder of Optimi. "We are excited to develop and supply this product from Canada, where we have the facility, the licensing, and the experience to make it into standardized pharmaceutical dosages."

Two dosage sizes, 50mg and 100mg, are planned in encapsulated format. The in-house development program covers standard operating procedures (SOPs) for finished drug encapsulation, dosage strengths, bottling, labeling, and packaging, alongside validation of the Company's manufacturing and analytical testing methods. The Company will provide an update upon completion of the program.

On April 18, 2026, a U.S. Executive Order named ibogaine compounds among the psychedelic therapies prioritized for accelerated Food and Drug Administration review and expanded patient access, and directed federal funding to match state investments in psychedelic research.² This has intensified attention on ibogaine and on the need for a reliable, GMP-grade supply.

In Canada, ibogaine is not a controlled substance under Canada's Controlled Drugs and Substances Act³; rather, it is regulated under the Food and Drugs Act (Canada) and is listed on Health Canada's Prescription Drug List.⁴ In contrast, ibogaine remains a Schedule I substance in the United States. Combined with Optimi's GMP infrastructure and current Health Canada licensing, this regulatory environment positions Canada, and Optimi specifically, as an advantageous base for the compliant manufacture and supply of ibogaine to support research and regulated access.

Ibogaine is a naturally occurring alkaloid derived from the root bark of the Tabernanthe iboga shrub, native to Central and West Africa. It has been studied for its potential to interrupt opioid withdrawal and craving, and for its effects on substance-use disorders, post-traumatic stress disorder (PTSD), and traumatic brain injury (TBI). A 2024 Stanford-led study of U.S. Special Operations veterans, published in Nature Medicine, reported reductions in PTSD, depression, anxiety, and functional disability in a cohort following a single ibogaine treatment protocol.⁵

Optimi is developing its ibogaine product at the Company's wholly owned GMP facility, which it also uses to manufacture psilocybin and MDMA. The Company supplies finished drug products and active pharmaceutical ingredients for clinical research and regulated patient access. Inquiries regarding product for special access programs and clinical trial supply may be directed to sales@optimihealth.ca.

Optimi's 5mg psilocybin capsules are prescribed commercially for treatment-resistant depression in Australia, with additional product from the run earmarked for planned clinical trials in the United States and Europe

VANCOUVER, BC, June 2, 2026 /CNW/ - via IBN – Optimi Health Corp. (NASDAQ: OPTH) (CSE: OPTI) (FSE: 8BN0) (the "Company" or "Optimi"), a commercial-stage pharmaceutical manufacturer of regulated psychedelic drug products, today announced the completion of a GMP production run of its 5mg psilocybin finished drug product.

The finished psilocybin capsules use the same formulation already prescribed to patients in Australia for treatment-resistant depression ("TRD"). The Company has also updated the product's bottling configuration to improve ease of use for prescribers and patients in the Australian market.

Additional product from the same production run is earmarked to support upcoming clinical research in the United States and clinical trials in Europe across various indications.

All stages of manufacturing were completed in-house and on-site at Optimi's facility under its Health Canada Drug Establishment Licence ("DEL"): biomass cultivation, extraction of the active pharmaceutical ingredient ("API") using Optimi's proprietary methods, encapsulation of the 5mg finished drug product, and packaging. The DEL authorizes Optimi to manufacture, package, label, test, store, and distribute controlled drug products, positioning the Company as a vertically integrated GMP supply layer for regulated psychedelic medicine.

The pharmaceutical grade facility is built to institutional security standards, including a Health Canada compliant Level 8 vault with the capacity to securely store controlled substances valued at up to C$100 million. Optimi is authorized by Health Canada to hold up to 20 kilograms of psilocybin and approximately 2,000 kilograms of biomass on site, giving the Company commercial-scale supply capacity.

"Optimi is one of the only companies to take naturally derived psilocybin from biomass to a finished drug product, entirely under one roof and on our own licence," said Dane Stevens, CEO and Co-Founder of Optimi. "What sets Optimi apart is that we serve both sides of this market simultaneously. The same  5mg psilocybin medicine prescribed in-clinic for treatment-resistant depression today, within a fully regulated framework, is the drug also being studied in clinical trials across a range of indications. We are proud to supply patients today and the researchers shaping what comes next."

Optimi supplies finished psilocybin and MDMA drug products to regulated markets internationally, in support of both patient access and clinical research. Building on its established export capability under the DEL, the Company is positioned to serve approved programs across multiple jurisdictions. Inquiries regarding product for special access programs and clinical trial supply may be directed to sales@optimihealth.ca.
