What is being measured

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

  1. Number of Participants With Treatment Performance Success

    Success: IOP < 15 mmHg or IOP reduced from baseline (pre-operative level) by ≥ 20% (without glaucoma reoperation, such as a trabeculectomy to improve aqueous drainage or implantation of another drainage implant).

    Measured: Day 1, Day 7, Week 3, Week 6, Month 3, Month 9, Month 12, Month 24, Month 36, Month 48 and Month 60

Secondary outcomes (1)
  1. Maintenance of Pressure Control

    Maintenance of pressure control throughout the follow-up period, as measured by IOP at each post-operative visit

    Measured: Day 1, Day 7, Week 3, Week 6, Month 3, Month 9, Month 12, Month 24, Month 36, Month 48 and Month 60

Questions about this trial

What is this clinical trial studying?

A study testing Glaucoma Drainage Device in people with Glaucoma, run by InnFocus Inc. at 1 site in Dominican Republic.

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 3 inclusion and 14 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 14 Jul 2021. 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 Dominican Republic. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Jul 2021). 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?

Number of Participants With Treatment Performance Success (time frame: Day 1, Day 7, Week 3, Week 6, Month 3, Month 9, Month 12, Month 24, Month 36, Month 48 and Month 60). 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 NCT00772330, which also lists 2 linked publications.

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 14 Jul 2021.
