  Purpose
The purpose of this study was to assess the safety and intraocular pressure (IOP)-lowering efficacy of changing to DuoTrav® from prior timolol 0.5% monotherapy in participants with open-angle glaucoma or ocular hypertension.

Condition Intervention Phase
Glaucoma Drug: Travoprost 0.004%/timolol maleate 0.5% fixed combination Phase 4

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Safety and Efficacy of Using the Travoprost/Timolol Fixed Combination (DuoTrav®) in Patients With Open-Angle Glaucoma or Uncontrolled Ocular Hypertension by Beta-blocker Monotherapy (Timolol 0.5%)

Primary Outcome Measures:
  • Mean Intraocular Pressure (IOP) Change at the Final Visit From Baseline (Prior Beta-blocker Monotherapy) [ Time Frame: Baseline, up to 6 weeks ]
    As measured by Goldmann applanation tonometry. High IOP (outside the normal range) can be a risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage). A more negative change indicates a greater amount of improvement.


Enrollment: 50
Study Start Date: February 2011
Study Completion Date: March 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)

Experimental: DuoTrav
Travoprost 0.004%/timolol maleate 0.5% fixed combination, one drop to the study eye nightly for up to 6 weeks
Drug: Travoprost 0.004%/timolol maleate 0.5% fixed combination
Other Name: DuoTrav

Criteria

Inclusion Criteria:

  • Clinical diagnosis of ocular hypertension, primary open-angle glaucoma or pigmentary glaucoma;
  • Intraocular pressure (IOP) of between 19 to 35 mmHg at any time of the day in at least one eye (designated as the study eye);
  • On a stable medication regimen for IOP reduction one week prior to the screening visit;
  • Best corrected visual acuity better than 20/200 (Snellen) or 1.0 (logMAR) in each eye;
  • Sign informed consent;
  • Other protocol-defined inclusion criteria may apply.

Exclusion Criteria:

  • Known medical history of allergy, hypersensitivity or low tolerance to any of the components of DuoTrav®;
  • Any abnormality that would preclude the reliable performance of applanation tonometry in either eye;
  • Infection in either eye;
  • Conventional or laser intraocular surgery in either eye 3 months prior to screening visit;
  • Risk for visual field or visual acuity worsening, in the opinion of the investigator;
  • Women of childbearing potential;
  • Pregnant or lactating women;
  • Any condition that, in the opinion of the principal investigator, could interfere with participation in the study, or that could present a risk to the participant.
  • Participation in another clinical study within 30 days before the screening visit;
  • Other protocol-defined exclusion criteria may apply.
