MELBOURNE, Australia, March 24, 2022 /PRNewswire/ -- Incannex Healthcare Limited (Nasdaq: IXHL) (ASX: IHL), ('Incannex' or the 'Company') a clinical-stage pharmaceutical company developing unique medicinal cannabis pharmaceutical products and psychedelic medicine therapies for unmet medical needs, today announced that it has executed a term sheet with binding commercial terms to wholly acquire APIRx Pharmaceutical USA, LLC ('APIRx'), subject to shareholder approval under ASX listing Rule 7.1.

About APIRx – First Mover in Pharmaceutical Medicinal Cannabinoid Product Development

APIRx is an innovative biotechnology company focused on research, development, and production of prescription pharmaceutical cannabinoid medicines. It has twenty-two (22) active clinical and pre-clinical research and development projects utilising proprietary technologies. The acquisition of APIRx brings to Incannex a diverse portfolio of promising therapeutic candidates targeted at treating an extensive range of conditions including pain, dementia, Parkinson's Disease, restless leg syndrome, gastrointestinal diseases, periodontitis, addiction disorders, skin conditions and ophthalmic conditions. A comprehensive table of the therapeutic candidates, their stage of development and their significant addressable markets are listed in Appendix A.

APIRx was established as a corporate entity in the Netherlands to amalgamate the intellectual property assets of medicinal cannabis pioneers, and APIRx co-founders, Dr George Anastassov and Mr Lekhram Changoer. Dr Anastassov and Mr Changoer have collaborated since 2003 to develop the largest privately held patent portfolio pertaining to pharmaceutical cannabinoid inventions globally. They previously licensed their technology to AXIM Biotechnologies Inc., where they were part of the lead management team, overseeing a peak market capitalisation of approximately US$1.2B in 2017 prior to the assets being privatised by APIRx.

Numerous pre-clinical studies and clinical trials over the APIRx therapeutic candidates have been undertaken to justify the intellectual property portfolio, which includes 19 granted patents and 23 pending patents. Key patents (detailed in Appendix B) relate to sustained oral mucosal delivery of cannabinoids and cannabinoid combinations through chewing gum, oral care cannabinoid compositions, cannabinoid ophthalmic solutions, topical compositions containing cannabinoids and cannabinoid extraction technologies.  

Medicated chewing gum ('MCG') is a novel drug delivery system growing in favour amongst the medical community due to widespread potential applications as an extended-release dosage form that provides a continuous release of the medicine contained. MCGs are fast acting as they release the active ingredients into the oral mucosa, reducing the potential for gastric intolerance amongst patients. These qualities, amongst others, make MCGs an excellent delivery system for medicinal combinations designed to treat sustaining pain and addiction disorders.

An example of a successful MCG is over-the-counter nicotine chewing gum (i.e., Nicabate for nicotine craving relief – noting this is not an APIRx product). A focus of the combined APIRx and Incannex group will be the ongoing development of APIRx's CheWell, CanQuit and CanQuit-O cannabinoid combination MCGs to treat cannabis addiction, nicotine addiction and opioid addiction.

Strategic Rationale

The acquisition of APIRx will significantly strengthen Incannex's position as a market leader at the forefront of cannabinoid and psychedelic treatment development. It will:

  • Add a large portfolio of intellectual property with granted and pending patents
  • Expand Incannex's addressable markets globally and addressable market sizes by over US$400bn per annum
  • Further enhance Incannex's technical and drug development capability by adding some of the industry's longest standing and best-known scientists to the Incannex team.
  • Expand the Company's drug delivery capability to include APIRx's patented delivery technologies.

APIRx will be entitled to nominate one board member to Incannex after completion of the proposed transaction.

APIRx Management – Dr George Anastassov and Mr Lekhram Changoer

Dr Anastassov and Mr Changoer are experienced clinical researchers with medical and scientific backgrounds. They will be employed by Incannex on a full-time basis following completion of the acquisition and will continue to drive the development of APIRx projects, whilst also assisting with the development of the Company's existing projects. They are experienced with liaising and negotiating with the U.S. Food and Drug Administration ('FDA'), having undertaken numerous pre- investigational new drug ('IND') meetings, and opening two (2) IND applications for the MedChew RL and the MedChew Dronabinol medicinal product candidates. Furthermore, APIRx has strong relationships with international academic institutions and research hospitals including Mount Sinai School of Medicine, New York (USA), University of St. Andrews (UK), Free University of Amsterdam (NL), University of Wageningen (NL), and Mauritsclinics (NL).

"We believe that bringing together Incannex and APIRx will bolster our position as a leader in the medicinal cannabinoid sector and will further set IHL apart from other players in the industry", stated CEO and Managing Director of Incannex, Mr. Joel Latham. "With sizeable addressable markets and intellectual property spanning a multitude of unmet medical needs, we're positioning Incannex to be a significant player in the pharmaceutical sectors of the future. I'm excited by this acquisition opportunity on multiple fronts and look forward to working with the APIRx team to deliver on our vision of providing treatments which will make genuine differences to the lives of millions of people".

APIRx co-founder, Dr George Anastassov said; "We are delighted to partner with the IHL team as we believe that our extensive experience and broad IP asset base is perfectly positioned for further development and expansion within the IHL organization. Both companies have proven track records to deliver innovative projects and the goal of this transaction to create the global leader in the cannabinoid, psychedelic, and combination pharmaceuticals space. We intend to do this by innovatively addressing conditions for which there are only modest, or no safe and effective, treatment options".

APIRx co-founder, Mr Lekhram Changoer said; "APIRx is bringing new drug delivery technologies backed by patents that, when combined with Incannex's existing intellectual property, will result in IHL being a state-of-the-art, industry-leading cannabinoid and psychedelic platform. The drug products developed utilising this broader portfolio of technologies gives us the opportunity to develop, in the clinic, a diverse range of innovative products addressing significant unmet medical needs. A post-acquisition Incannex will also have greater presence in the United States and Europe, which may benefit the Company to more efficiently undertake multi-site clinical trials that will ultimately be required for FDA clinical trial programs aimed at drug approval".

Next Steps

Incannex has commenced the documentation of the long form contract required to complete the proposed transaction. Shareholder approval will be sought by means of an extraordinary general meeting ('EGM') of shareholders. The EGM will be called and announced in due course. Key terms of the acquisition are detailed in Appendix C below. In anticipation of the completion of the transaction, the Incannex medical and scientific team continue thorough assessment of the APIRx projects to best prioritise the development of the APIRx therapeutic candidates. Incannex anticipates budgeting approximately A$5.0M of expenditure on the APIRx product suite in the first 12 months. However, the budget may be re-assessed to up to A$10M following the conclusion, in April, of the Loyalty Option Offer, that could raise up to approximately A$28M in development capital for the Company.

The proposed acquisition transaction is not a related party transaction.

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