Study groups in NCT01510145
Study group	Role	What they receive
TRAVATAN® BAK-free	Experimental	Travoprost 0.004% BAK-free, 1 drop self-administered to the study eye(s) once daily, every evening at around 8:00 pm, for 12 weeks. Receives: Drug: Travoprost 0.004% BAK-free

What is being measured

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

Change in Intraocular Pressure (IOP) at 12 Weeks From Prior Therapy (Baseline)
IOP (fluid pressure inside the eye) was measured by Goldmann applanation tonometry. A higher IOP can be a greater risk for developing glaucoma or glaucoma progression (leading to optic nerve damage). A more negative change indicates a greater amount of improvement. One eye was chosen as the study eye, and only data from the study eye were used for the efficacy analysis.
Measured: Baseline, Week 12

Secondary outcomes (1)

Percentage of Subjects Who Reach Target IOP (≤18 mmHg)
IOP (fluid pressure inside the eye) was measured by Goldmann applanation tonometry. A higher IOP can be a greater risk for developing glaucoma or glaucoma progression (leading to optic nerve damage). One eye was chosen as the study eye, and only data from the study eye were used for the efficacy analysis.
Measured: Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Travoprost 0.004% BAK-free in people with Open-angle 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 9 inclusion and 12 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 13 Jun 2014. 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 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?

Yes. Results are posted in the registry (first posted 13 Jun 2014). 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?

Change in Intraocular Pressure (IOP) at 12 Weeks From Prior Therapy (Baseline) (time frame: Baseline, Week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01510145, which also lists 1 linked publication.

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 13 Jun 2014.
