What is being measured

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

  1. Proportion of Patients Achieving Total Posterior Vitreous Detachment (PVD) Without Creation of an Anatomical Defect

    The primary efficacy endpoint was the proportion of patients achieving total PVD without creation of an anatomical defect (ie, retinal hole, retinal detachment) based on surgeon visualization at the beginning of vitrectomy prior to suction or any other mechanical intervention.

    Measured: Day 7

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ocriplasmin 25µg, Ocriplasmin 75µg and Ocriplasmin 125µg in people with Vitrectomy, run by ThromboGenics at 20 sites in United States.

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 1 inclusion and 4 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 17 Dec 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites in United States. 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. Some participants in this study may receive a placebo. 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 30 Jan 2013). 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?

Proportion of Patients Achieving Total Posterior Vitreous Detachment (PVD) Without Creation of an Anatomical Defect (time frame: Day 7). 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 17 Dec 2014.
