Dosing completed in 115 participant bioavailability/bioequivalence clinical trial for proprietary sleep apnea drug candidate IHL-42X
Rhea-AI Summary
Incannex Healthcare (Nasdaq: IXHL) has completed participant dosing in the IHL-42X Bioavailability/Bioequivalence (BA/BE) clinical trial for its proprietary sleep apnea drug candidate. The study involved 115 participants who completed four treatment periods, comparing IHL-42X to FDA reference listed drugs Marinol and Taro acetazolamide. No serious adverse events were reported during the study.
IHL-42X, a fixed dose combination of dronabinol and acetazolamide, targets obstructive sleep apnea (OSA), a condition affecting millions in the USA with no registered pharmaceutical treatment. The trial's data will be analyzed to generate comparative pharmacokinetic profiles, potentially allowing Incannex to rely on existing safety and toxicology data for future regulatory submissions.
Concurrently, the Phase 2/3 FDA IND-enabling RePOSA clinical trial for IHL-42X continues, having commenced dosing in May 2024.

NEW YORK and MELBOURNE, Australia, July 30, 2024 (GLOBE NEWSWIRE) -- Incannex Healthcare Inc. (Nasdaq: IXHL), (‘Incannex’ or the ‘Company’), a clinical-stage pharmaceutical company developing proprietary medicinal cannabinoid products and psychedelic-assisted psychotherapies, is pleased to announce that it has completed participant dosing in the IHL-42X Bioavailability/Bioequivalence (BA/BE) clinical trial.
IHL-42X comprises two drugs, dronabinol (synthetic delta-9-tetrahydrocannabinol (THC)), and acetazolamide. The BA/BE clinical trial was designed to compare the bioavailability of dronabinol and acetazolamide in IHL-42X as a fixed dose combination drug to the FDA reference listed drugs Marinol and Taro acetazolamide administered in isolation. The BA/BE study also assessed the effect of food on the bioavailability of the drug substances in IHL-42X. All participants in the study completed four treatment periods, each consisting of a single dose each of IHL-42X, Marinol or acetazolamide under fasted conditions, or IHL-42X under fed conditions. Blood samples were then collected at predefined intervals and analysed for levels of acetazolamide, THC and major THC metabolites. Participants were also monitored for adverse events throughout the study. 115 participants completed all four treatment periods and no serious adverse events were reported during the study.
Data collected during the study will be processed and analysed over the coming months. This will generate information on the pharmacokinetics of each of the active pharmaceutical ingredients in IHL-42X compared to the relevant reference listed drugs. These comparative pharmacokinetic profiles will facilitate the Company’s ability to rely on safety and toxicology data for the reference listed drugs in future regulatory submissions. The adverse event data from the BA/BE study will also contribute to the safety profile of IHL-42X as a combination product.
Incannex Chief Scientific Officer Dr Mark Bleackley said “Completion of dosing in the BA/BE study is an important milestone in the IHL-42X research program. The pharmacokinetics of cannabinoids are highly-variable so having data across the four treatment periods from this many subjects will provide incredibly valuable data for Incannex in the continued development of IHL-42X. The ability to rely on safety and toxicology data for the refence listed drugs reduces the burden on Incannex and allows us to focus on safety and efficacy of the drug product in OSA patients. Thank you to the trial sites, our clinical research organisation and, most importantly, the volunteers who participated in the study.”
About IHL-42X
IHL-42X is a synergistic composition of dronabinol, a synthetic form of Delta-9 Tetrahydrocannabinol (THC), and acetazolamide, a carbonic anhydrase inhibitor. Results from a Phase 2 proof of concept clinical trial undertaken by Incannex were published in 2022. Incannex observed that IHL-42X reduced average apnoea-hypopnoea index (‘AHI’) by an average of
About Obstructive Sleep Apnea
Sleep apnea is the most common sleep-related breathing disorder. It involves the narrowing of the upper airway during sleep, interfering with a person’s breathing, decreasing oxygen uptake, resulting in poor-quality sleep1. Untreated sleep apnea leads to serious long-term adverse health outcomes including hypertension, cardiovascular disease, heart attack, cognitive impairments, anxiety and depression, irritability and daytime fatigue increasing the risk of accidents. There are no pharmacotherapy (drug) treatments available to those afflicted. The current ‘standard of care’ is the Continuous Positive Airway Pressure (‘CPAP’) machine. However, patient compliance to CPAP is low due to various factors related to patient discomfort. Incannex anticipates greatly improved treatment compliance and outcomes from a pharmaceutical product, such as IHL-42X, subject to further clinical assessment and approval from regulators. Regardless of the discomfort caused by CPAP, the global annual market for sleep apnea detection and treatment using CPAP and other breathing aides is approximately US
