Incannex Engages Catalent for Development and cGMP Manufacture of
Psilocybin Drug Product for Clinical Trials and Commercial Potentiality

Highlights:

Incannex has engaged Catalent for the development and cGMP manufacture of Incannex's own psilocybin drug product
The psilocybin is designed for use in Incannex's ongoing psilocybin-assisted psychotherapy "PsiGAD" clinical development program for generalised anxiety disorder
The psilocybin drug product may also have potential uses in psilocybin-assisted psychotherapy programs in Australia under the new Authorised Prescriber Scheme for psychedelic-assisted psychotherapy recently announced by the TGA in Australia
Development of the drug product includes generation of the necessary quality and stability data to support future regulatory filings including IND applications.

Melbourne, Australia, March 03, 2023 - Incannex Healthcare Limited (Nasdaq: IXHL) (ASX: IHL), ('Incannex' or the 'Company') a pharmaceutical company developing proprietary medicinal cannabinoid products and psychedelic medicine therapies for unmet medical needs, is pleased to announce that it has engaged Catalent ('Catalent') to develop and manufacture a cGMP-grade psilocybin drug product for: (1) use in Incannex's proprietary psilocybin-assisted psychotherapy drug development program and (2), potential use in the Therapeutic Goods Association ('TGA') Authorised Prescriber Scheme for psychedelic-assisted psychotherapy in Australia.

Commencing development and manufacture of a psilocybin drug product follows an internal analysis of the interim data from the PsiGAD phase 2 clinical trial, giving Incannex confidence to proceed with formulation development and cGMP manufacture of its own psilocybin. Interim results from the PsiGAD trial remain internally confidential to maintain blinding and integrity of the trial, however, interim statistical analysis from the independent data safety monitoring board (DSMB) will be released soon, when available.

Incannex CEO and Managing Director Mr Joel Latham said; "The TGA's decision to down schedule psilocybin for Authorised Prescribers to prescribe psilocybin for treatment-resistant depression has important implications for our long term outlook. Having our own source of pharmaceutical grade psilocybin not only allows our company to freely undertake clinical trials, it also creates a potential opportunity to be a part of providing therapies to patients in Australia in the future, something that the Company is actively assessing."

Public Announcement (NASDAQ: IXHL) (ASX: IHL)

Catalent has been engaged to develop the formulation, generate required quality and stability data for regulatory filings, and establish cGMP manufacture of a drug product to be used in future clinical trials. The proposed manufacturing process will be designed so that it will be scalable to commercial supply levels when appropriate.

Incannex Chief Scientific Officer Dr Mark Bleackley said; "Engaging Catalent for development and cGMP manufacture of Incannex's psilocybin drug project is an important milestone for the PsiGAD program. The resulting drug product, and supporting data, will form an important component of future regulatory filings and will facilitate Incannex's development of psilocybin assisted psychotherapy for generalised anxiety disorder. This therapy has the potential to help millions of people whose lives are seriously impacted by generalised anxiety disorder for whom current treatment options have not been effective. We look forward to working with Catalent on the continued development of this exciting drug product."

This announcement has been approved for release to ASX by the Incannex Board of Directors.
