PURPOSE: To evaluate the safety and efficacy of adding fixed-combination brinzolamide 1%/brimonidine 0.2% (BBFC) as adjunctive therapy to travoprost 0.004% (TRAV) in patients with open-angle glaucoma or ocular hypertension. DESIGN: Multicenter, randomized, double-masked, parallel-group phase 4 clinical trial. METHODS: setting: Multicenter; 32 sites in the United States. PATIENT POPULATION: Total of 233 patients with open-angle glaucoma or ocular hypertension and with mean intraocular pressure (IOP) ≥21 mm Hg and <32 mm Hg while receiving once-daily TRAV monotherapy. INTERVENTION: Masked BBFC or vehicle (3 times daily) adjunctive to TRAV for 6 weeks. MAIN OUTCOME MEASURE: Mean diurnal IOP averaged over 8 AM, 10 AM, 3 PM, and 5 PM time points at week 6. Superiority of BBFC+TRAV over vehicle+TRAV was based on statistical significance of a treatment difference favoring BBFC+TRAV. RESULTS: Mean diurnal IOP at week 6 (least squares mean ± standard error) was 17.6 ± 0.4 mm Hg and 20.7 ± 0.4 mm Hg in the BBFC+TRAV and vehicle+TRAV groups, respectively (between-group difference, -3.2 ± 0.5 mm Hg; P < .0001). Superiority of BBFC+TRAV over vehicle+TRAV was established. Mean and percent diurnal IOP change from baseline were significantly greater with BBFC+TRAV compared with vehicle+TRAV (P < .0001 for both). Conjunctival hyperemia was the most common treatment-related adverse event in either group (BBFC+TRAV, 12.8%; vehicle+TRAV, 6.0%). CONCLUSIONS: Adjunctive treatment with BBFC added to TRAV resulted in lower mean diurnal IOP after 6 weeks of treatment compared with vehicle added to TRAV; this difference was both statistically and clinically significant.
