Efficacy of Changing to DuoTrav® (Travoprost 0.004%/Timolol 0.5% BAK-Free Fixed Combination) From Prior Therapy
December 2, 2014 updated by: Alcon Research
Assessing the Efficacy and Tolerability of Changing to DuoTrav® (Travoprost 0.004%/Timolol 0.5% BAK-Free Fixed Combination), as Replacement Therapy in Patients Previously on Prior Prostaglandin Fixed Combination
The purpose of this study is to assess efficacy and tolerability of changing to DuoTrav® (Travoprost 0.004%/Timolol 0.5% BAK-free) from prior Xalacom® or Ganfort® fixed combination pharmacotherapy in patients with open-angle glaucoma or ocular hypertension with uncontrolled intraocular pressure (IOP).

Description
Inclusion Criteria:
- Clinical diagnosis of ocular hypertension, open-angle glaucoma, or pigment dispersion glaucoma in both eyes.
- On a stable IOP-lowering regimen of prostaglandin fixed combination (either Xalacom or Ganfort) within 4 weeks prior to the Screening Visit.
- IOP between 19 and 35 mmHg at any time of day in at least 1 eye.
- Best corrected visual acuity (BCVA) of 6/60 (20/200 Snellen; 1.0 LogMAR) or better in each eye.
- Willing to discontinue the use of all other ocular hypotensive medication(s) prior to receiving the study medication for the entire course of the study.
- Other protocol-defined inclusion criteria may apply.
Exclusion Criteria:
- Known medical history of allergy, hypersensitivity, or poor tolerance to any component of DuoTrav® deemed clinically significant in the opinion of the Principal Investigator.
- Corneal dystrophies in either eye.
- Risk of visual field or VA worsening as a consequence of participation in the study, in the investigator's best judgment.
- Any disease or condition that would preclude the safe administration of a topical beta-blocker, present a special risk to the subject, or interfere with optimal participation in the study.
- Women who are pregnant or lactating.
- Participation in any other investigational study within 30 days prior to the Screening Visit.
- Other protocol-defined exclusion criteria may apply.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in intra-ocular pressure (IOP) at final visit from prior therapy (i.e., from baseline)
Time Frame: 12 weeks
|
Goldmann applanation tonometry will be performed at the baseline visit and the 12-week visit to record IOP.
Change in IOP will be calculated.
IOP will be measured in mmHg.
|
12 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of patients who reach target IOP (≤18mmHg)
Time Frame: 12 weeks
|
Goldmann applanation tonometry will be performed at the 12-week visit to record IOP.
Percentage of patients who reach target IOP will be calculated by comparing patients with IOP ≤18mmHg to the overall study population.
|
12 weeks
|
Change in Ocular Surface Disease Index (OSDI) score at final visit from baseline
Time Frame: 12 weeks
|
An OSDI questionnaire will be completed by the subject at the baseline visit and at the 12-week visit.
For each visit, an overall OSDI score will be calculated using individual item responses, and the change in OSDI score from baseline will be calculated.
|
12 weeks
|
Change in ocular hyperemia score at final visit from baseline
Time Frame: 12 weeks
|
Ocular hyperemia will be assessed by qualified personnel at the baseline visit and again at the 12-week visit, and change from baseline will be calculated.
|
12 weeks
