Clinical stage pharmaceutical development company, Incannex Healthcare Limited (ASX: IHL) (NASDAQ: IXHL), (‘Incannex’ or the ‘Company’), is pleased to provide its quarterly activities report and appendix 4C for the period ended 30 September 2022. Incannex is undertaking a multitude of U.S. Food and Drug Administration (‘FDA’) programs for cannabinoid pharmaceutical products and psychedelic medicine therapies administered by health professionals.

Positive preliminary results from Phase 1 clinical trial of IHL-675A

During the quarter, Incannex received approval from the Bellberry Human Research Ethics Committee (‘HREC’) for a Phase 1 clinical trial investigating its proprietary multi-use, anti-inflammatory drug IHL-675A. IHL-675A is a combination cannabinoid drug comprising cannabidiol (‘CBD’) and hydroxychloroquine (‘HCQ’) in a fixed dose combination. IHL-675A was observed to outperform either CBD and HCQ in various pre-clinical models of inflammation, including in vivo models of rheumatoid arthritis, inflammatory bowel disease and lung inflammation.

Participant recruitment for the trial commenced in August, and the preliminary results from the trial were released to ASX and Nasdaq after the end of the quarter in October. The trial measured the safety, tolerability, and pharmacokinetic profiles of IHL-675A compared to the reference listed drugs, Epidiolex (CBD) and Plaquenil (HCQ). Three cohorts of 12 participants (n = 36) received either IHL-675A, CBD or HCQ and the assessments will be identical across the three arms of the trial.

IHL-675A was observed to be well tolerated, with no adverse events of concern to the conclusion of the 4-week observation period. Furthermore, no serious adverse events have been reported. The pharmacokinetics of each active pharmaceutical ingredient will be reported in the full clinical study report, which will be available to Incannex in Q1 2023.

As a result of positive preliminary observations, Incannex has commenced the arrangement of Phase 2 clinical studies, initially in patients with rheumatoid arthritis. Phase 2 studies to assess IHL-675A in patients with inflammatory bowel disease and lung inflammation are also being planned.

Scale-up manufacture of cGMP IHL-216A and pre-IND meeting

In August, Incannex engaged Curia Global, Inc. (‘Curia’) to further develop and manufacture GMP-grade IHL-216A, Incannex’s proprietary inhaled drug product for the treatment of concussion and traumatic brain injury (‘TBI’). Curia’s engagement follows proof-of-concept studies which established the optimal inhaled formulation of IHL-216A at an experimental scale. Curia is engaged to scale-up the fill-finish manufacture of IHL-216A in compliance with Current Good Manufacturing Practice (‘cGMP’), also generating data on the quality and stability of IHL-216A to support future regulatory filings.

Subsequent to the end of the quarter, Incannex participated in a constructive pre-Investigational New Drug Application (‘pre-IND’) meeting with FDA over IHL-216A. Incannex submitted a pre-IND meeting package to FDA in August 2022. The meeting package included a description of the unique formulation developed by Incannex, an overview of the proposed clinical development plan, and specific questions Incannex submitted on the regulatory requirements for opening an Investigational New Drug application (‘IND’).

In written correspondence, FDA provided valuable, multidisciplinary feedback on the proposed clinical development of IHL-216A and acknowledged that treatment of TBI is a significant unmet medical need that requires innovative treatment solutions. The FDA also confirmed that the FDA505(b)2 application was the appropriate regulatory pathway for IHL-216A, whereby some of the information required for marketing approval may derive from studies already completed on the drug components of IHL-216A and in the public domain.

Advancement of IND opening clinical trial for IHL-42X

In June 2022, Incannex announced positive results from full analysis of its Phase 2 clinical trial on the effect of IHL-42X to treat patients with obstructive sleep apnoea (‘OSA’). In particular, low dose IHL-42X exhibited superior safety and efficacy metrics to mid and high doses. Low dose IHL-42X reduced AHI in trial participants by an average of 50.7%, compared to baseline, with 25% of participants experiencing a reduction in AHI of greater that 80%. Oxygen desaturation index was reduced by an average of 59.7%, relative to baseline, which improved patient sleep quality and reduced cardiovascular stress. In low dose IHL-42X samples, THC blood concentrations were well below the limits for impaired driving the morning after dose administration. Importantly, IHL-42X was well tolerated with low dose IHL-42X observed to have a lower number of total treatment emergent adverse events than placebo.

As stated in the June quarterly, Incannex considers the trial results to be a major success and step forward to provide confidence for further assessment in pivotal studies necessary for drug registration. During the quarter, the Company continued with the arrangement of operational imperatives necessary to open an IND with FDA and expects to release a standalone update on the IHL-42X program within the December quarter.

Advancement of manufacturing and development of APIRx cannabinoid drug candidates

During the quarter, Incannex finalised all matters related to the acquisition of APIRx Pharmaceuticals USA LLC (‘APIRx’) to aggregate the world’s largest portfolio of patented medicinal cannabinoid drug formulations. Twenty-two (22) additional clinical and pre-clinical research and development projects have been transferred to Incannex, representing aggregate addressable markets of approximately US$400B per annum. These projects are underpinned by an intellectual property portfolio that includes 19 granted patents and 23 pending patents.

Initial high-priority drug candidates resulting from the acquisition are:

• MedChew Dronabinol for chemotherapy induced nausea and vomiting
• MedChew Rx for pain and spasticity in patients with multiple sclerosis
• CanQuit and CanQuitO – chewables that combine nicotine and cannabinoids and cannabinoids and opioid antagonists for smoking cessation and opioid addiction, respectively
• CheWell – high-bioavailability chewable tablet to be implemented in adolescent drug addiction studies, among other indications
• CanChew – patented high-bioavailability and long-acting CBD chewing gum for the over-the-counter market
• Renecann - topical cannabinoid development candidates for various skin diseases.

The Incannex scientific advisory team has been arranging for the manufacture of the high-priority drug candidates in preparation for further research and development activities.

Incannex appoints FDA regulatory affairs expert Mr Robert B. Clark to the Board of Directors

During the quarter, Incannex announced the appointment of experienced pharmaceutical executive Mr Robert B. Clark to the Board of Directors. Mr Clark is a senior-level strategic regulatory affairs expert with over 38 years of US and Global regulatory experience, including >20 years with Pfizer Inc. and >10 years with Novo Nordisk A/S.

Cannabinoid and psychedelic pharmacotherapies represent a growing area of research and hold the potential to treat various conditions for which effective options are limited”. Mr Clark holds a Master's in Science in Pharmacology from the New York Medical College.

Psychedelic therapies: psilocybin and psychotherapy for Generalised Anxiety Disorder (“Psi-GAD”)

During the September 2022 quarter, the Psi-GAD Phase 2a clinical trial led by Dr Paul Liknaitzky at Monash University (‘Monash’) continued. The aim of the trial is to assess participants with generalised anxiety disorder following the administration of psilocybin and specialised psychotherapy sessions. Importantly, the trial protocol and development plan incorporate treatment innovations currently unseen in the field of psychedelic therapy and have been discussed with FDA officials in a pre-IND meeting undertaken in the December quarter of 2021.

Primary outcomes from the trial are safety, efficacy and tolerability, and secondary outcomes are assessments of quality of life, functional impairment, and comorbidities. A preliminary analysis of patient data will be conducted by an independent statistician after 30 patients have completed primary endpoint assessment. This preliminary analysis will allow the trial investigators to inform the second part of the trial (n=42) and/or the follow-up Phase 2b clinical trial that Incannex is actively planning.

Participant therapy continues and approximately 30 participants are anticipated to complete their therapies in the current December quarter. The preliminary analysis of patient data is anticipated to be released in Q1 in 2023.

Also, during the September quarter, Incannex advanced negotiations with Monash University over a new psychedelic treatment paradigm for severe forms of one or more anxiety disorders. Negotiations involve a research agreement for the development of a new therapy that involves virtual reality (‘VR’) exposure response therapy (‘ERP’) combined with psychedelics. The associated research and development will be led by Dr Paul Liknaitzky at Monash University, a highly reputable, globally recognised, and innovative university that ranked #40 in the world in the US News and World Report 2022. It is anticipated that the initial clinical trial will assess efficacy, safety, tolerability, and optimal dose of the treatment method.
