| NCT05857384 | Bioavailability, Bioequivalence and Tolerability of IHL-42X Compared to the Reference Drugs | PHASE1 | COMPLETED | 125 | — | — | Sep 8, 2023 | Jul 31, 2024 | Jan 17, 2025 | 4 | Australia |
Phase 2 - Assess the change in AHI compared to baseline
Assess the proportion of IHL-42X that is taken up and enters the circulation post dose.
Compare the proportion of IHL-42X taken up and enters the circulation to the reference listed drugs for dronabinol and acetazolamide. It will be determined whereby 90% confidence interval for the ratio of averages of measures Cmax and AUC0-inf for IHL-42X and the reference listed drug.
Assess the effect of food on the uptake and absorption of IHL-42X by measuring Cmax (Maximum observed drug concentration)
Assess the effect of food on the uptake and absorption of IHL-42X by measuring Tmax (time of the maximum drug concentration)
Assess the effect of food on the uptake and absorption of IHL-42X by measuring AUC0-last (Area under the drug concentration-time curve, from time zero to time of last measurable concentration)
Assess the effect of food on the uptake and absorption of IHL-42X by measuring AUC0-inf (Area under the drug concentration-time curve from time zero to infinity)
Assess the effect of food on the uptake and absorption of IHL-42X by measuring AUC0-12h (Area under the drug concentration-time curve from time zero to 12 hours)
Assess the effect of food on the uptake and absorption of IHL-42X by measuring AUC0-24h (Area under the drug concentration-time curve from time zero to 24 hours)
Assess the effect of food on the uptake and absorption of IHL-42X by measuring t1/2 (the elimination half-life)
Assess the effect of food on the uptake and absorption of IHL-42X by measuring kel (Terminal elimination rate constant)
Assess the effect of food on the uptake and absorption of IHL-42X by measuring CL/F (Apparent total body clearance)
Assess the effect of food on the uptake and absorption of IHL-42X by measuring Vz/F (Apparent volume of distribution)
