Efficacy of Travoprost/Timolol for Uncontrolled Intraocular Pressure
June 27, 2016 updated by: Alcon Research
Prospective, Randomized, Multi-Center Study to Evaluate the Efficacy and Tolerability of DuoTrav® in Patients Previously Uncontrolled on a Beta-blocker
The purpose of this study is to demonstrate superior intraocular pressure (IOP) control with travoprost 0.004% / timolol 0.5% compared to beta-blocker monotherapy in participants with open-angle glaucoma or ocular hypertension.

Description
Inclusion Criteria:
- Have a clinical diagnosis of either open angle glaucoma or ocular hypertension.
- Currently on beta-blocker monotherapy (for >30 days) and would benefit, in the opinion of the investigator, from further intraocular pressure (lOP) reduction.
- Have a mean baseline lOP of >18 mmHg and <32 mmHg in at least one eye.
- Must be able to understand and sign an Informed Consent form.
- Other protocol-specified inclusion criteria may apply.
Exclusion Criteria:
- Use of medication excluded by the protocol.
- Diseases, illnesses, infections, or ocular abnormalities excluded by the protocol.
- Ocular surgeries or procedures excluded by the protocol.
- Best-corrected visual acuity (BCVA) score worse than 55 ETDRS letters (equivalent to 20/80 Snellen, 0.60 logMAR or 0.25 decimal).
- Hypersensitivity to prostaglandin analogues or any component of the study medications in the opinion of the investigator.
- Women of childbearing potential if pregnant, test positive for pregnancy at Screening visit, breastfeeding, or not in agreement to use adequate birth control methods to prevent pregnancy throughout the study.
- Other protocol-specified exclusion criteria may apply.

Active Comparator: Beta-blocker
Participant's current beta-blocker monotherapy, 1 drop instilled in the study eye twice daily (morning and evening) for 4 weeks, followed by travoprost 0.004% / timolol 0.5% fixed combination ophthalmic solution, 1 drop instilled in the study eye once daily (evening) for 4 additional weeks.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Least Squares Mean Intraocular Pressure (IOP) at 8AM in the Study Eye
Time Frame: Week 4
|
IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and is measured in millimeters of mercury (mmHg).
A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage).
One eye (study eye) contributed to the analysis.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Mean Change From Baseline in IOP (8AM) at Week 4 in the Study Eye
Time Frame: Baseline (Day 0), Week 4
|
IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and is measured in mmHg.
A negative change indicates an improvement.
One eye (study eye) contributed to the analysis.
|
Baseline (Day 0), Week 4
|
Percentage Change From Baseline in IOP (8AM) at Week 4 in the Study Eye
Time Frame: Baseline (Day 0), Week 4
|
IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and is measured in mmHg.
A more negative percent change from baseline indicates a greater amount of improvement, i.e., a reduction of IOP.
One eye (study eye) contributed to the analysis.
