Comparison of Istalol™ 0.5% QD (Timolol Maleate/Sorbitol Complex, ISTA Pharmaceutical) to Brimonidine Tartrate 0.1% BID as Adjunctive Therapy to Latanoprost 0.005% in Adults With Ocular Hypertension (OHT) or Open-Angle Glaucoma (OAG)

Completed · Phase 4

Conditions studied: Ocular Hypertension, Open-Angle Glaucoma

In brief

To assess the additional benefit of common adjunctive classes on the diurnal IOP curve in patients assessed as needing additional treatment to reach target intraocular pressure (IOP). To demonstrate superiority of IOP control with Istalol 0.5% QD compared to Brimonidine Tartrate 0.2% BID as adjunctive therapy in adults with uncontrolled IOP's (determined by P.I. based on target pressures) currently treated with Latanoprost 0.05% in the study eye(s).
