Three Month Efficacy/Safety Study With a 3-Month Safety Extension of Brinzolamide 1%/Brimonidine 0.2% vs. Brinzolamide 1% or Brimonidine 0.2%

This study consisted of 7 visits conducted during 2 sequential phases: the screening/eligibility phase, which included a screening visit and 2 eligibility visits, and the treatment phase, which included 4 on-therapy visits conducted at Week 2, Week 6, Month 3, and Month 6. A washout period based on previous ocular medication preceded Eligibility Visit 1. Subjects who met all inclusion/exclusion criteria at both eligibility visits were randomized to 1 of 3 study drug groups. The study was designed to evaluate the efficacy and safety of Brinzolamide/Brimonidine over a 3-month period, with an additional 3 months of study drug exposure intended to provide further safety data.
