Study Endpoints

Primary Endpoints

Change From Baseline in Mean Diurnal Intra Ocular Pressure (IOP) in Study Eye at Day 14: Stage I
Stage I: Baseline, Day 14

Diurnal IOP was defined as the mean IOP over 24 hours. IOP was measured using Goldmann applanation tonometer. IOP was measured in both the eyes, and the eye with higher IOP reading at the 2 eligibility visits was referred as 'study eye' for efficacy assessment. If both the measurements were equal, right eye was selected as the study eye. IOP was measured twice in the same eye, and if the difference between 2 measurements was less than or equal to 2 millimeter of mercury (mmHg), the mean of the 2 readings was recorded as the IOP at that time point. If the difference between 2 readings was greater than 2 mmHg, a third consecutive reading was taken and the median IOP was recorded as the IOP at that time point. Mean IOP was reported as the average of individual participants' mean or median IOP values. Change from baseline = diurnal IOP at baseline - diurnal IOP at Day 14.

Change From Baseline in Mean Diurnal Intra Ocular Pressure (IOP) in Study Eye at Day 28: Stage II
Stage II: Baseline, Day 28

Diurnal IOP was defined as the mean IOP over 24 hours. IOP was measured using Goldmann applanation tonometer. IOP was measured in both the eyes, and the eye with higher IOP reading at the 2 eligibility visits was referred as 'study eye' for efficacy assessment. If both the measurements were equal, right eye was selected as the study eye. IOP was measured twice in the same eye, and if the difference between 2 measurements was less than or equal to 2 mmHg, the mean of the 2 readings was recorded as the IOP at that time point. If the difference between 2 readings was greater than 2 mmHg, a third consecutive reading was taken and the median IOP was recorded as the IOP at that time point. Mean IOP was reported as the average of individual participants' mean or median IOP values. Change from baseline = diurnal IOP at baseline - diurnal IOP at Day 28.

Number of Participants With Treatment Emergent Ocular Adverse Events (AEs): Stage I
Stage I: Day 1 up to 28 days after last dose of study medication (up to 44 days)

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Treatment-emergent are events between first dose of study medication and up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state. Ocular AEs were the events which were localized in the ocular region.

Number of Participants With Treatment Emergent Ocular Adverse Events (AEs): Stage II
Stage II: Day 1 up to 28 days after last dose of study medication (up to 59 days)

An AE was any untoward medical occurrence in a participant who received study medication without regard to possibility of causal relationship. Treatment-emergent are events between first dose of study medication and up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state. Ocular AEs were the events which were localized in the ocular region.
