  Purpose

The purpose of this study is to demonstrate equivalent safety and IOP-lowering effectiveness of two Travoprost/Timolol combination products in patients diagnosed with open-angle glaucoma or ocular hypertension. This global study will be conducted in the US (C-07-64, NCT00672997) and Japan (C-08-08, NCT00760539).


Condition Intervention Phase
Open-Angle Glaucoma
Ocular Hypertension
Drug: Travoprost 0.004%/Timolol 0.5% BAC-free ophthalmic solution
Drug: Travoprost 0.004%/Timolol 0.5% ophthalmic solution
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Six-Week, Multi-Center, Double-Masked, Safety and Efficacy Study of Travoprost 0.004%/Timolol 0.5% BAC-free Compared to Travoprost 0.004%/Timolol 0.5% in Patients With Open-Angle Glaucoma or Ocular Hypertension

Primary Outcome Measures:
  • Mean Intraocular Pressure (IOP) combined across all visits and timepoints [ Time Frame: Week 2 (9 AM, 11 AM, and 4 PM); Week 6 (9 AM, 11 AM, and 4 PM) ] [ Designated as safety issue: No ]
    IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and measured in millimeters of mercury (mmHg).


Secondary Outcome Measures:
  • Percentage of patients with IOP <18 mmHg or IOP percent reduction of ≥ 30% by visit [ Time Frame: Week 2 (9 AM, 11 AM, and 4 PM); Week 6 (9 AM, 11 AM, and 4 PM) ] [ Designated as safety issue: No ]
    IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and measured in millimeters of mercury (mmHg).

  Eligibility

Ages Eligible for Study:   20 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Open-angle glaucoma or confirmed ocular hypertension.
  • Mean IOP in at least one eye, the same eye(s):22-36 mmHg at 9 AM on eligibility visits 1 & 2 and 21-36 mmHg at 11 AM and 4 PM on Eligibility Visits 1 & 2.
  • Sign an informed consent form.
  • Discontinued use of all IOP-lowering medications(s) for a minimum of 4 days to a minimum of 27 days or more prior to the Eligibility 1 Visit.
  • Other protocol-defined inclusion criteria may apply.

Exclusion Criteria:

  • Females of childbearing potential who are pregnant, planning to become pregnant during the study period, breast-feeding, or not using adequate birth control measures.
  • Any form of glaucoma other than open-angle glaucoma (with or without a pigment dispersion or pseudoexfoliation component) or confirmed ocular hypertension.
  • History or current evidence of chronic or recurrent severe inflammatory eye disease in either eye.
  • History or current evidence of clinically relevant or progressive retinal disease such as retinal degeneration, diabetic retinopathy, or retinal detachment in either eye.
  • Best-corrected visual acuity (BCVA) worse than 0.6 logMAR in either eye.
  • Severe central visual field loss in either eye.
  • Not able to safely discontinue use of all IOP-lowering ocular medication(s) according to the Ocular Hypotensive Medication Washout Schedule.
  • History or current evidence of bronchial asthma, or severe chronic obstructive pulmonary disease (COPD) that would in the opinion of the investigator preclude the safe administration of a topical beta-blocker.
  • History or other evidence of severe illness or any other conditions which would make the subject, in the opinion of the investigator, unsuitable for the study.
  • Other protocol-defined exclusion criteria may apply.
