Details and patient eligibility

About

The purpose of this study is to demonstrate the additive effect of brinzolamide 1%/brimonidine 0.2% (SIMBRINZA® suspension) in subjects with either open angle glaucoma or ocular hypertension who are currently on a prostaglandin analogue (PGA) monotherapy.

Full description

This study was divided into 2 sequential phases. The Screening/Eligibility Phase included one Screening Visit and two Eligibility Visits, during which subjects washed out of all other intraocular pressure (IOP)-lowering medications and dosed with TRAVATAN Z®, XALATAN®, or LUMIGAN®, 1 drop instilled in each eye once daily for 28 days. Subjects who met all inclusion/exclusion criteria were randomized at the second Eligibility Visit. The Treatment Phase consisted of two on-therapy visits (Week 2 and Week 6).

Enrollment: 282 patients

Sex: All

Ages: 18+ years old

• Previously prescribed TRAVATAN Z® 0.004%, XALATAN® 0.005%, or LUMIGAN® 0.01% monotherapy for at least 28 days prior to the Screening Visit;

• Ocular infection or ocular inflammation within the past 3 months;
• Best-corrected visual acuity score worse than approximately 20/80 Snellen;
