A Phase II, Prospective, Two-Stage, Double-Masked, Randomized, Multi-Center, Controlled, Dose-Response Study Assessing the Safety and Ocular Hypotensive Efficacy of AR-17043 and PG043 (AR-17043/Latanoprost) Ophthalmic Solutions in Subjects With Elevated Intraocular Pressure

The purpose of this two-stage clinical trial is to assess the safety and hypotensive efficacy of AR-17043 and PG043 ophthalmic solutions in subjects with open-angle glaucoma (OAG) or ocular hypertension (OHT).

Detailed Description

The study consists of two sequential stages under a single protocol. Stage 1 and Stage 2 will enroll independent participant cohorts. Subject enrolled in Stage 1 will not be eligible to participate in Stage 2.

During Stage 1, approximately 100 adult subjects with OAG or OHT will be randomized to 5 arms: 3 different concentrations of AR-17043, placebo comparator, or netarsudil 0.02% (Rhopressa®) for a treatment duration of 7 days.

During Stage 2, approximately 350 adult subjects with OAG or OHT will be randomized to 5 arms: low and high concentrations of PG043 (AR-17043/latanoprost 0.005%), AR-17043 high concentration, latanoprost, or netarsudil 0.02%/latanoprost 0.005% (Rocklatan®) for a treatment duration of 28 days.
