This study will evaluate and confirm that the efficacy and tolerability of a New Preservative-free Generic Formulation of 0.2% Brimonidine/0.5% Timolol fixed-Combination Eye Drops solution in single dose container is not worse to the marketed preservative-containing formulation Combigan®Eye Drops solution in Patients with OpenAngle Glaucoma or Ocular Hypertension already on Treatment with IOP-lowering Drugs and Low Intraocular Pressure (IOP=21 mmHg)

Therapeutic Equivalence (non-inferiority), Randomized, Observer-blind, two Parallel Group, Clinical Trial for Comparing the Efficacy and Tolerability of a new Generic Formulation of 0.2% Brimonidine/0.5% Timolol fixed-Combination Eye Drops solution free of Preservatives vs. Combigan® Eye Drops solution in Patients with Open- Angle Glaucoma, or Ocular Hypertension, already on Treatment with IOP-lowering Drugs and Low Intraocular Pressure (IOP=21 mmHg) - ?herapeutic equivalence trial between two formulations of 0.2% Brimonidine/0.5% Timolol

Design outcomes

Primary

MeasureTime frame
Main Objective: To confirm the clinical non-inferiority of a generic fixed combination of Brimonidine 0.2%/Timolol 0.5% eye drops solution in single dose container which is preservative-free, compared to the marketed preservative-containing Combigan® eye drops solution in patients with open angle glaucoma, or ocular hypertension, already on treatment with IOP-lowering drugs and low intraocular pressure (IOP=21 mmHg) by examining the average change of diurnal IOP from end of study to baseline.;Secondary Objective: •Secondary efficacy objectives are the average change of diurnal IOP measured between baseline and days 7 and 14 and the proportion of patients with measured IOP <21 mmHg at the end of the clinical trial. •Proportion of withdrawals for therapeutic failure (diurnal IOP =21 mmHg) at any time point during or at the end of week 4. ;Primary end point(s): Average diurnal IOP change from baseline to end of week 4.;Timepoint(s) of evaluation of this end point: At week 4

Secondary

MeasureTime frame
Secondary end point(s): •Average change of diurnal IOP from baseline to end of week 1. •Average change of diurnal IOP from baseline to end of week 2. •Proportion of patients with an IOP less than 21 mmHg at the end of week 4. •Proportion of withdrawals for therapeutic failure (diurnal IOP =21 mmHg) at any time point during or at the end of week 4. ;Timepoint(s) of evaluation of this end point: At weeks 1, 2 , baseline and 4 week
