About this study

Official title: A 6-Week Proof-of-Concept Study Evaluating the Safety and IOP-Lowering Efficacy of Travoprost/Brinzolamide Fixed Combination Ophthalmic Suspension in Subjects With Open-Angle Glaucoma or Ocular Hypertension

The purpose of this study is to evaluate Travoprost/Brinzolamide fixed combination (Trav/Brinz) administered twice daily as compared to each of its marketed components (TRAVATAN Z® solution and AZOPT® suspension) and to the unfixed combination of TRAVATAN Z® plus AZOPT® in lowering intraocular pressure (IOP).

Read the detailed description

This study was divided into two phases conducted in sequence. Phase I was the Screening/Eligibility Phase, which included a Screening Visit, followed by two Eligibility Visits. Phase II was the randomized, double-masked, 6-week Treatment Phase which included on-therapy visits at Week 2 and Week 6. Travoprost was administered in 1 of 3 concentration levels (A-C), where A=lowest and C=highest.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean IOP at Week 6

    IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and 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) was used for the analysis.

    Measured: Week 6, 8 AM, 10 AM, 12 PM, 4 PM, and 8 PM

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Dose Level A / Brinzolamide 1% ophthalmic suspension, Dose Level B / Brinzolamide 1% ophthalmic suspension and Dose Level C / Brinzolamide 1% ophthalmic suspension in people with Glaucoma and Ocular Hypertension, run by Alcon Research.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Dec 2015. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Dec 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean IOP at Week 6 (time frame: Week 6, 8 AM, 10 AM, 12 PM, 4 PM, and 8 PM). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Dec 2015.
