Open-angle Glaucoma, Ocular Hypertension
Conditions
Brief summary
To evaluate ocular hypotensive efficacy and safety of PG324 Ophthalmic Solution compared to Netarsudil (AR-13324) Ophthalmic Solution and Latanoprost Ophthalmic Solution.

Extent of Exposure
Exposure to study medication in days for all treatment groups
Time frame: 12 months
Population: The safety population= all randomized subjects who received at least 1 dose of study medication. The safety population summarized subjects as-treated. 1 Subject was randomized to netarsudil but received latanoprost. Therefore, 1 less subject is in the netarsudil group and 1 additional subject is in the latanoprost group for the safety population.
