Who may be able to join

  • Ocular laser surgery within the past three months as determined by patient history and/or examination in either eye.
  • Any abnormality preventing reliable applanation tonometry of either eye.
  • Angle grade less than Grade 2 in either eye, as measured by gonioscopy (extreme narrow angle with complete or partial closure), assessed within the previous 12 months.
  • Cup/disc ratio greater than 0.80 in either eye, assessed within the previous six months.
  • Severe central visual field loss in either eye, defined as a sensitivity of ≤ 10 bB in at least two of the four visual field test points, closest to the point of fixation, assessed within the previous six months.
  • Unable to safely discontinue all IOP lowering medication, for a minimum period of 28 days prior to Baseline Visit.
  • Unable to safely discontinue all glucocorticoid medications administered by any route. Before the Eligibility Visit, patients must have performed a Wash Out of at least four weeks for any intermittent glucocorticoid medications and must be able to remain off these medications for the duration of the study.
  • Use of any additional topical or systemic ocular hyposensitive medication during the study.
  • History of bronchial asthma, or severe chronic obstructive pulmonary disease that would preclude the safe administration of a topical beta-blocker.
  • Less than 30 days stable dosing regimen before the Screening Visit of any non-glaucoma medications or substances administered by any route and used on a chronic basis that may affect IOP. These may include, but are not limited to the following:
  • Sympathomimetic agents
  • Antimuscarinic agents
  • Antihistamines
  • Phenothiazines
  • Tricyclic antidepressants
  • Beta-antagonist blocking agents
  • Alpha agonists
  • Alpha-adrenergic blocking agents
  • Calcium channel blockers
  • Angiotensin converting enzyme inhibitors
  • Cardiac gylcosides
  • History or other evidence of severe illness or any other conditions which would make the patient, in the opinion of the investigator, unsuitable for the study.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Travoprost 0.004% / Timolol maleate 0.5% in people with Open-angle Glaucoma and Ocular Hypertension, run by Alcon Research at 1 site in United Kingdom.

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 6 inclusion and 39 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 22 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Reduction in intraocular pressure (time frame: week 4, week 12). 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 22 Nov 2016.
