Phase Ⅰ/Ⅱ, Double-Masked, Randomized, Vehicle-Controlled Study of H-1337 Ophthalmic Solution for Glaucoma and Ocular Hypertension.
Ophthalmology. Glaucoma(2022)
Abstract
PURPOSE:To perform a phase Ⅰ/Ⅱ evaluation of an H-1337 ophthalmic solution in subjects with primary open-angle glaucoma (POAG) or ocular hypertension (OHT).
DESIGN:This was a phase I/II, randomized, double-masked, vehicle-controlled, dose-response study conducted at 6 private practice sites in the United States. The study was registered with clinicaltrials.gov as NCT03452033.
PARTICIPANTS:Eighty-seven subjects with bilateral POAG or OHT were enrolled.
METHODS:After washout of ocular hypotensive medications as required, the subjects were randomized to receive either the H-1337 ophthalmic solution at 0.06%, 0.2%, and 0.6% or its vehicle twice daily unilaterally in the study eye for the first 3 days and then twice daily in both eyes from day 4 to 28.
MAIN OUTCOME MEASURES:The primary efficacy end point was the mean change in intraocular pressure from baseline (day 0) for each group on day 28 at hour 4 compared with the vehicle.
RESULTS:In the primary efficacy end point, i.e., mean change from the baseline on day 28 at hour 4, the mean change from the baseline was - 4.45 ± 3.801, - 5.16 ± 3.114, - 4.93 ± 3.110, and - 0.39 ± 2.355 in the 0.06%, 0.2%, and 0.6% H-1337 and vehicle groups, respectively. The difference between each active group and the vehicle group was statistically significant (P < 0.0001). Treatment-emergent adverse events (TEAEs) occurred in 49% of subjects who received H-1337 (range, 41% [0.2% arm]-64% [0.6% arm] across the H-1337 arms) and 18% of subjects who received the vehicle. The majority of TEAEs were mild in severity; 3 subjects who received H-1337 had a TEAE of moderate intensity (instillation site erythema, blurred vision, and muscle strain).
CONCLUSIONS:The H-1337 ophthalmic solution showed clinically and statistically significant ocular hypotensive activity and was well tolerated, with a relatively low incidence of hyperemia.
