Incannex Receives Ethics Approval to Commence Phase 1 Clinical Trial of Multi-Use Anti-Inflammatory Drug IHL-675A
Incannex Healthcare Limited (NASDAQ: IXHL) has announced the approval of a phase 1 clinical trial for its cannabinoid drug IHL-675A by the Bellberry Human Research Ethics Committee. The trial aims to assess the drug's safety and pharmacokinetics at CMAX Clinical Research in Adelaide, Australia, with patient recruitment set to begin in August 2022. IHL-675A combines cannabidiol (CBD) and hydroxychloroquine (HCQ), showing better anti-inflammatory potential in preclinical studies. Successful trial outcomes will support regulatory submissions for conditions like rheumatoid arthritis, inflammatory bowel disease, and lung inflammation.

MELBOURNE, Australia, July 21, 2022 /PRNewswire/ -- Incannex Healthcare Limited (Nasdaq: IXHL) (ASX: IHL), ('Incannex' or the 'Company') a clinical-stage pharmaceutical company developing unique medicinal cannabinoid pharmaceutical products and psychedelic medicine therapies for unmet medical needs, is pleased to announce that it has 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. Synergistic anti-inflammatory activity of CBD and HCQ was observed in these distinct pre-clinical studies and was evidence to support the Company's international patent application over the drug.
CEO and Managing Director, Mr Joel Latham said; "Approval to begin our Australian phase 1 trial is a significant milestone for Incannex and clinicians treating patients with disorders for which inflammation is the underlying cause. There's a growing trend whereby patients are using CBD to treat, or supplement their existing treatments, for inflammation disorders. We have observed in established models of inflammation that IHL-675A is a stronger anti-inflammatory cannabinoid-based drug than CBD administered alone, hence we are delighted and excited to take IHL-675A to the clinic for the first time".
The trial will measure 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) will receive either IHL-675A, CBD or HCQ and the assessments will be identical across the three arms of the trial.
Chief Scientific Officer of Incannex Healthcare, Dr Mark Bleackley said; "The aims of the trial are to demonstrate that there are no, or minimal, additional side effects associated with the combination of CBD and HCQ compared to each drug alone and that the uptake and metabolism, otherwise known as pharmacokinetics, of the two drugs do not materially interfere with one another".
Subject to clinical success, the results of the phase 1 clinical trial will form part of three U.S. Food and Drug Administration ('FDA') investigational new drug ('IND') applications for each of the initial three indications the Company is pursuing for IHL-675A. These indications are rheumatoid arthritis, inflammatory bowel disease and lung inflammation, representing major markets for Incannex to pursue with IHL-675A. Once the IND applications are evaluated and approved, the Company intends to conduct clinical trials partly or wholly in the United States.
The trial will be conducted at CMAX Clinical Research in Adelaide, South Australia, and managed by Avance Clinical. Patient recruitment is anticipated to commence in August 2022.
IHL-675A Formulation and Manufacturing of Clinical Trial Supply Completed
Incannex is also pleased to announce that formulation development of IHL-675A has been completed and the first batch of product has been manufactured.
The formulation development process included multiple experiments conducted to determine the ideal excipients to use in formulation of IHL-675A. Other assessments included the characterization of the dissolution of both active pharmaceutical ingredients (CBD and HCQ) from the IHL-675A gel capsule and ensuring that the dissolution profile was consistent with the reference listed drugs.
Data from the characterization of the IHL-675A gel capsules, the quality assessment and early timepoints in the stability analysis were a critical component of the HREC submission package. These results, along with data from the ongoing stability studies are essential to support future regulatory submissions, including IND and new drug applications with the FDA and corresponding applications with other regulatory agencies. Stability studies to establish the shelf life of the IHL-675A gel capsule product are also underway.
The manufacturing facilities at Incannex's formulation partner have been inspected and approved for good manufacturing practices (GMP) by multiple regulatory agencies including FDA, TGA, Health Canada and MHRA. Production of IHL-675A soft gel capsules can quickly ramp up to commercial quantities when required.
About IHL-675A
IHL-675A comprises a combination of HCQ and CBD. HCQ is a disease modifying anti-rheumatic drug that regulates the activity of the immune system, which may be overactive in some conditions. HCQ can modify the underlying disease process, rather than simply treating the symptoms. Incannex has demonstrated that IHL-675A components, CBD and HCQ, act synergistically to inhibit production of key inflammatory cytokines in an in vitro study of human cells and in four distinct successful in vivo experiments using established models of inflammation.
Incannex has evaluated the results of these experiments and believe IHL-675A to be a multi-use drug candidate suitable for the prevention and treatment of inflammation, with an initial focus on inflammatory lung conditions (acute respiratory distress syndrome, COPD, asthma, and bronchitis), rheumatoid arthritis, and inflammatory bowel disease.
The treatment of these indications has a combined global annual market size of exceeding US
This announcement has been approved for release to ASX by the Incannex board of directors.
