24-hr Intraocular Pressure Control With SIMBRINZA ®

Alcon Research162 enrolled

Overview

The purpose of this study is to evaluate differences between treatments in mean change from baseline in 24-hr intraocular pressure (IOP) at Week 4.

Subjects will undergo washout of pre-study IOP-lowering medications for the appropriate duration, then undergo 2 eligibility visits. Eligible subjects will be randomized 1:1, to receive masked SIMBRINZA ® or Vehicle for 4 weeks. Two 24-hour visits will be conducted (Day 0 and Week 4) during which intraocular pressure will be collected every 2 hours. The expected duration of subject participation in the study is 10 weeks.

Exclusion Criteria: * Women of childbearing potential who are pregnant, intend to become pregnant during the study, breast-feeding, or not using adequate birth control; * Diagnosed with any form of glaucoma other than open angle glaucoma or ocular hypertension; * Ocular surgeries or procedures excluded by the protocol; * Diseases, illnesses, infections, or ocular abnormalities excluded by the protocol; * Best-corrected visual acuity score less than 55 ETDRS letters (equivalent to approximately 20/80 Snellen) in either eye; * Other protocol-specific exclusion criteria may apply.

Outcomes

Primary Outcomes

Least Squares Mean Change From Baseline in 24-hr Intraocular Pressure (IOP) at Week 4

IOP (fluid pressure inside the eye) was measured in millimeters of mercury (mmHg). Change was calculated by taking the change from baseline at each time point and averaging the available changes. A higher IOP can be a greater risk for developing glaucoma or glaucoma progression (leading to optic nerve damage). A more negative change indicates greater improvement. Only one eye (study eye) contributed to the analysis.

Time frame: Baseline (Day 0), Week 4

Secondary Outcomes

Least Squares Mean Change From Baseline in Daytime IOP at Week 4

IOP (fluid pressure inside the eye) was measured in mmHg. Change was calculated by taking the change from baseline at each time point (8 AM through 8 PM) and averaging the available changes. A higher IOP can be a greater risk for developing glaucoma or glaucoma progression (leading to optic nerve damage). A more negative change indicates greater improvement. Only one eye (study eye) contributed to the analysis.

Time frame: Baseline (Day 0), Week 4

Least Squares Mean Change From Baseline in Nocturnal IOP at Week 4

IOP (fluid pressure inside the eye) was measured in mmHg. Change was calculated by taking the change from baseline at each time point (10 PM through 6 AM) and averaging the available changes. A higher IOP can be a greater risk for developing glaucoma or glaucoma progression (leading to optic nerve damage). A more negative change indicates greater improvement. Only one eye (study eye) contributed to the analysis.

Time frame: Baseline (Day 0), Week 4

Least Squares Mean Change From Baseline in IOP for Each Time Point (8 AM Through 6 AM) at Week 4

IOP (fluid pressure inside the eye) was measured in mmHg. A higher IOP can be a greater risk for developing glaucoma or glaucoma progression (leading to optic nerve damage). A more negative change indicates greater improvement. Only one eye (study eye) contributed to the analysis.
