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).

Primary Outcome Measures:
  • Change in intra-ocular pressure (IOP) at final visit from prior therapy (i.e., from baseline) [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    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.

Secondary Outcome Measures:
  • Percentage of patients who reach target IOP (≤18mmHg) [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    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.

  • Change in Ocular Surface Disease Index (OSDI) score at final visit from baseline [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    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.

  • Change in ocular hyperemia score at final visit from baseline [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    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.

Accepts Healthy Volunteers:   No

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.
