Study Description

Brief Summary:

To evaluate the effect on trabecular outflow facility of Netarsudil ophthalmic solution 0.02% compared to placebo

Condition or disease	Intervention/treatment	Phase
Primary Open Angle Glaucoma or Ocular Hypertension	Drug: Netarsudil Ophthalmic Solution 0.02%; Other: Placebo Comparator	Phase 2

Detailed Description:

Trabecular outflow facility is a measure of aqueous humor dynamics; effect of netarsudil on this parameter as well as on intraocular pressure and episcleral venous pressure was evaluated in this study. Netarsudil treatment was given in one eye and placebo given in contralateral eye for 7 consecutive days.

Outcome Measures

Primary Outcome Measures :

1. Mean Change From Baseline in the Mean Diurnal Trabecular Outflow Facility [ Time Frame: Study treatment was administered for 7 days, and outcome measures collected on Day 8 ]
   Mean diurnal change from baseline in trabecular (tonographic) outflow facility.
2. Mean Percent Change From Baseline in the Mean Diurnal Trabecular Outflow Facility. [ Time Frame: Study treatment was administered for 7 days, and outcome measures collected on Day 8 ]
   Mean diurnal change from baseline in trabecular (tonographic) outflow facility.

Secondary Outcome Measures :

1. Mean Change From Baseline in Episcleral Venous Pressure (EVP) and in Intraocular Pressure (IOP) [ Time Frame: Study treatment was administered for 7 days, and outcome measures collected on Day 8 ]
   Mean diurnal change from baseline in mean diurnal IOP measured using a Pneumatonometer and mean diurnal EVP using a custom-modified slit-lamp mounted venomanometer. (EVP conducted at a single site in only 9 participants)
2. Mean Percent Change From Baseline in Episcleral Venous Pressure (EVP) and in Intraocular Pressure (IOP) [ Time Frame: Study treatment was administered for 7 days, and outcome measures collected on Day 8 ]
   Mean diurnal change from baseline in mean diurnal IOP measured using a Pneumatonometer and mean diurnal EVP using a custom-modified slit-lamp mounted venomanometer. (EVP conducted at a single site in only 9 participants)
