Stonegate Capital Partners has updated its coverage on Incannex Healthcare Inc. following the company's continued advancement of clinical and patient-reported evidence for IHL-42X in treating obstructive sleep apnea. The update comes after full Phase 2 RePOSA data and exit-interview analyses revealed substantial progress in the treatment's development. Both low and high-dose formulations of IHL-42X demonstrated statistically significant reductions in Apnea-Hypopnoea Index compared to placebo, with the high-dose arm showing maximum AHI reductions reaching 83%.

The clinical significance of these findings is reinforced by patient-reported outcomes from exit interviews, where 57.6% of participants reported perceived improvement in their obstructive sleep apnea symptoms. Most of these participants described the change as meaningful to their daily life, indicating potential quality of life benefits beyond clinical metrics. The treatment was well tolerated across both dose cohorts, suggesting its potential for broad application in the sleep apnea patient population.

Incannex Healthcare's progress with IHL-42X represents an important development in sleep medicine, where current treatment options often face compliance challenges. The combination of strong clinical efficacy data and positive patient experience reports positions IHL-42X as a potentially transformative therapy for obstructive sleep apnea. The company's research efforts have yielded promising results that could address significant unmet needs in sleep disorder treatment.

The financial position of Incannex Healthcare supports continued development, with $68.9 million in reported cash and cash equivalents providing resources for further clinical advancement. Additional positive Phase 2 results for PSX-001 further demonstrate the company's research capabilities across multiple therapeutic areas.
