Incannex Healthcare Inc. Reports Fiscal Second Quarter 2025 Financial Results and Business Updates

• Positive IHL-42X PK findings for the treatment of Obstructive Sleep Apnea (OSA) support future 505(b)(2) New Drug Application (NDA) submission
• New OSA Clinical Advisory Board Announced; Appoints Dr. Alison Wimms, Representing ResMed

NEW YORK and MELBOURNE, Australia, Feb. 14, 2025 (GLOBE NEWSWIRE) — Incannex Healthcare Inc. (Nasdaq: IXHL), (Incannex), a clinical-stage biopharmaceutical company leading the way in developing oral combination medicines, today reported fiscal second quarter financial results and provided business highlights for the quarter ended December 31, 2024.

“Patients with obstructive sleep apnea need new and convenient therapeutic options to manage this serious, chronic and life-threatening disease. We are enthusiastic about the potential for IHL-42X, an oral, once-daily treatment that uniquely targets physiological pathways responsible for the airway obstruction characteristic of OSA. We achieved a key milestone for our OSA program, reporting positive top-line results from a pharmacokinetics (PK) and safety study of IHL-42X, conducted alongside our global Phase 2/3 RePOSA study,” said Joel Latham, Incannex’s President and Chief Executive Officer.

“Our new OSA clinical advisory board brings together leading scientific and industry experts, and we are pleased to welcome Dr. Alison Wimms, representing ResMed, a recognized leader in the sleep medicine field. The OSA advisory board will provide valuable insights and guidance for our ongoing global IHL-42X Phase 2/3 RePOSA clinical trial. Looking ahead, we are committed to executing our clinical programs and are energized by the upcoming catalysts, including the top-line readout from the U.S. Phase 2 portion of the IHL-42X trial expected in the first half of 2025.”

Operational Highlights

• Established an IHL-42X OSA Clinical Advisory Board and appointed Alison Wimms, Ph.D. as an advisor, representing ResMed. Dr. Wimms brings two decades of sleep medicine industry and research expertise to Incannex’s new OSA advisory board. The CAB marks an important step in fostering collaboration as we advance our global Phase 2/3 ‘RePOSA’ clinical study in OSA.

  The RePOSA Global Phase 2/3 clinical trial is progressing well, with strong recruitment and enrollment at the U.S. sites. Building on the positive momentum and continued interest in patient recruitment, the trial design includes expansion to both U.K. and U.S. sites for the Phase 3 trial. Additionally, we have successfully completed manufacturing of the IHL-42X clinical supply needed to initiate Phase 3.

Clinical Highlights

• Announced positive top-line results from the completed pharmacokinetics (PK) and safety study of IHL-42X, a novel, oral fixed-dose combination of acetazolamide and dronabinol for the treatment of OSA. In line with expectations, the study demonstrated bioavailability of IHL-42X, confirming delivery of both drug components. Moreover, the PK profiles of the active ingredients in IHL-42X were similar to those established for the reference listed drugs, and total drug exposure levels from IHL-42X were found to be equivalent to those of the reference listed drugs, building a scientific bridge to the established safety and toxicology data. These results have the potential to support a future FDA 505(b)(2) new drug application (NDA) and will aid in the analysis of the global Phase 2/3 RePOSA study.

Financial Results

• General and Administration (G&A) expenses for the three months ended December 31, 2024 were $3.6 million USD, compared to $5.3 million USD for the same period in 2023. The decrease was primarily attributable to lower other employee benefits, resulting from a reduction in the amount of restricted stock issued to our directors and officers.
• Research and development (R&D) expenses for the three months ended December 31, 2024 totaled $1.4 million USD, compared to $2.6 million USD for the same period in 2023. The primary R&D expense for the period was associated with the global Phase 2/3 RePOSA clinical trial for OSA, while the primary decrease in expense was due to the completion of the IHL-42X safety and pharmacokinetics clinical trial, in addition to pausing the Phase 2 IHL-675A Australia study in rheumatoid arthritis in order to re-allocate use of resources to a larger U.S. Phase 2 IHL-675A clinical study, where an expedited regulatory pathway may be available.
• Net loss for the three-month period ended December 31, 2024 was $6.3 million USD, compared to $4.3 million USD for the three months ended December 31, 2023.
• Cash and cash equivalents as of December 31, 2024 were $2.1 million USD, compared to $3.6 million USD as of September 30, 2024.

About IHL-42X

IHL-42X, an oral fixed-dose combination of acetazolamide and dronabinol, is currently in Phase 2/3 clinical studies for the treatment of obstructive sleep apnea (OSA). Designed to act synergistically, IHL-42X uniquely targets two physiological pathways associated with the intermittent hypoxia (IH) and hypercapnia that characterize OSA. In a prior Australian Phase 2 clinical trial, IHL-42X was shown to reduce the Apnea-Hypopnea Index (AHI) in all dosage strengths, with the lowest dose reducing AHI by an average of 51 percent relative to baseline. RePOSA, a global Phase 2/3 clinical trial is underway, evaluating IHL-42X in individuals with OSA who are either non-compliant, intolerant, or naïve to positive airway pressure devices, including CPAP, with the Phase 2 portion conducted in the United States. The expanded Phase 3 portion will include sites in the United Kingdom and European Union. A topline readout from the U.S. Phase 2 portion is anticipated in the first half of 2025.

About IHL-675A

IHL-675A is an oral fixed-dose combination of cannabidiol and hydroxychloroquine sulfate designed to target two distinct pathways, while acting synergistically to alleviate inflammation. IHL-675A was observed to be well tolerated and bioavailable in an Australian Phase 1 clinical trial. IHL-675A was also observed to reduce inflammatory markers and disease scores across multiple animal inflammatory disease models and in vitro assays in preclinical evaluation. Moving forward the company plans to focus resources on a larger U.S. Phase 2 study, where an expedited regulatory pathway may be available, enrolling patients with rheumatoid arthritis (RA).

About PSX-001

PSX-001 is Incannex’s oral synthetic psilocybin drug candidate, administered in combination with psychotherapy, for patients diagnosed with moderate-to-severe Generalized Anxiety Disorder (GAD). In the Australian Phase 2 “PsiGAD1” clinical trial, PSX-001 was observed to reduce anxiety scores and be well-tolerated in GAD patients. Forty-four percent of the subjects in the psilocybin group exhibited a clinically meaningful improvement of at least 50% in anxiety score from baseline; a ‘response rate’ more than four times higher than that of the placebo group. Incannex plans to submit full results from the PsiGAD1 Phase 2 trial for publication in a peer-reviewed scientific journal. The “PsiGAD2” Phase 2 trial is expected to recruit 94 patients with GAD, including those currently treated with selective serotonin reuptake inhibitors (SSRIs), who meet the study inclusion and exclusion criteria in the United States and United Kingdom.
