Optimi Health Welcomes Expanded Psychedelic-Assisted Therapy
Access Under Updated Authorized Prescriber Framework in Australia
Updated TGA recommendations broaden therapist eligibility, accept a wider range of treatment settings, and reinforce Australia’s
position as the world’s leading commercial market for prescribed psilocybin and MDMA
VANCOUVER, British Columbia, May 29, 2026 – via
IBN – Optimi Health Corp. (NASDAQ: OPTH) (CSE: OPTI) (FSE: 8BN0) (the “Company” or “Optimi”), a commercial-stage psychedelic pharmaceutical manufacturer, today acknowledged the final recommendations
published by the Therapeutic Goods Administration (“TGA”) following its targeted consultation on the Authorized Prescriber (“AP”) scheme for psilocybin and MDMA.
Under the AP scheme, authorized psychiatrists may prescribe Optimi’s MDMA for the treatment of post-traumatic stress disorder (“PTSD”) and
psilocybin for treatment-resistant depression (“TRD”) from the Company’s GMP-compliant production facility in Canada, making Australia the first country in the world to recognize, and
regulate, both substances as medicines for these indications.
The updated framework, published following stakeholder consultation that closed on
May 19, 2026, introduces material changes to how psychedelic-assisted psychotherapy (“PAT”) is delivered in Australia. The changes are designed to expand the eligible workforce, open new categories of treatment setting, and
accelerate scaling of Australia’s commercial program, which remains the leading reference point globally for prescribed psilocybin and MDMA care.
“The TGA’s updated framework is a meaningful step toward unlocking the workforce, settings, and prescriber base needed to further scale
psychedelic-assisted therapy in Australia,” said Dane Stevens, CEO of Optimi. “After over two years of regulated commercial use, no serious adverse events have been reported under the scheme. Australia continues to be the most advanced
commercial reference point for what reimbursed, real-world psychedelic care looks like, and Optimi is positioned to support that expansion as patient volumes increase.”
Therapy Team Composition Has Been Broadened
Under the
updated framework, the therapy dyad must include at least one therapist registered with a National Board and the AP psychiatrist is required to be physically present on-site during administration of the
medicine and to conduct real-time patient screening and informed consent.
The second practitioner in the dosing room may be drawn from the wider pool of
suitably trained professionals, including psychotherapists, counsellors, social workers, and Aboriginal and Torres Strait Islander health workers. The AP psychiatrist is responsible for determining qualifications and competency of any additional
practitioner, subject to oversight by the relevant Human Research Ethics Committee (“HREC”).
Australia’s training ecosystem supports
the Certificate in Psychedelic-Assisted Therapy (“CPAT(TM)”), delivered by Mind Medicine Australia, which has trained more than 750 clinicians. The program is accredited under Australian Medical CPD Standards, recognized by HRECs and the
TGA, and offers 127+ CPD hours, clinical experience pathways, and a national alumni network.
