Incannex Healthcare (NASDAQ:IXHL) has announced positive topline results from its RePOSA Phase 2 clinical trial for IHL-42X, a novel oral drug candidate for obstructive sleep apnea (OSA). The trial demonstrated significant improvements in key endpoints, with the drug reducing the Apnoea-Hypopnoea Index (AHI) by up to 83% in the high-dose group and 79% in the low-dose group.

The study, involving 121 adult participants, showed statistically significant improvements across multiple measures including oxygen desaturation, sleep quality, and patient-reported outcomes. Both dosage groups demonstrated strong efficacy, with 33.3% to 41.2% of patients achieving >30% AHI reduction. The drug exhibited an excellent safety profile with no serious adverse events reported.

Following these positive results, Incannex is preparing for an End-of-Phase 2 meeting with the FDA to discuss the path toward Phase 3 trials and potential commercialization.
