Double-masked Study of PG324 Ophthalmic Solution in Patients With Glaucoma or Ocular Hypertension


To evaluate ocular hypotensive efficacy and safety of PG324 Ophthalmic Solution compared to Netarsudil (AR-13324) Ophthalmic Solution and Latanoprost Ophthalmic Solution.

Following completion of the Month 12 study visit procedures, subjects will be offered the opportunity to participate in a 2-month observational (i.e., non-interventional) trial extension.

Full Title of Study: “A Prospective, Double-masked, Randomized, Multi-center, Active-controlled, Parallel-group 12-month Study Assessing the Safety and Ocular Hypotensive Efficacy of PG324 Ophthalmic Solution Compared to AR-13324 Ophthalmic Solution, 0.02% and Latanoprost Ophthalmic Solution, 0.005% in Subjects With Elevated Intraocular Pressure”

Clinical Trial Outcome Measures

Primary Measures

  • Intraocular Pressure (IOP)
    • Time Frame: Primary efficacy endpoint measured for 3 months (data collected at 08:00, 10:00 and 16:00 hours at Day 15, Day 43 and Day 90)
    • The primary efficacy variable was mean IOP at 08:00, 10:00 and 16:00 hours at Day 15, Day 43 and Day 90, as measured by Goldmann applanation tonometry. Secondary analysis were conducted as a part of safety measurements to month 12 on treatment.

Secondary Measures

  • Extent of Exposure
    • Time Frame: 12 months
    • Exposure to study medication in days for all treatment groups
