About this study
Official title: An Open-Label, Ascending-Exposure-Time, Single Center Trial to Evaluate the Pharmacokinetic Properties of Ocriplasmin (Generic Name of the Molecule Microplasmin) Intravitreal Injection in Subjects Scheduled for Primary Pars Plana Vitrectomy
To evaluate the pharmacokinetic properties of intravitreal ocriplasmin 125 µg dose when administered at different time-points prior to planned primary pars plana vitrectomy (PPV)
Read the detailed description
Open-label, ascending-exposure-time, single center trial in which a total of 36 subjects will be enrolled. The time to remove the vitreous will be recorded and a vitreous sample will be obtained at the beginning of vitrectomy for determination of ocriplasmin activity; 32 subjects will receive 125 μg ocriplasmin intravitreal injection prior to vitrectomy and 4 subjects will not receive ocriplasmin intravitreal injection prior to vitrectomy (control arm).
Study drug will be administered in the mid-vitreous by injection. The study eye will be examined after study drug injection to exclude retinal non-perfusion or other complications.

What is being measured
The primary outcome is the main question the study is designed to answer.
Ocriplasmin Activity Levels in Vitreous Samples Obtained at the Beginning of Vitrectomy.
Vitreous samples were obtained at the beginning of vitrectomy in subjects at various times relative to ocriplasmin injection (post-injection), for the determination of ocriplasmin activity (Group 1 [5-30 minutes]; Group 2 [31-60 minutes]; Group 3 [2-4 hours]; Group 4 [24 hours ±2 hours]; Group 5 [7 days ±1 day]. Subjects in Group 6 (control) did not receive the ocriplasmin injection.
Measured: 5-30 minutes, 31-60 minutes, 2-4 hours, 1 day, or 7 days after ocriplasmin injection

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing ocriplasmin in people with Vitrectomy, run by ThromboGenics at 1 site in Belgium.
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 13 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 1 site in Belgium. 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 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?
Ocriplasmin Activity Levels in Vitreous Samples Obtained at the Beginning of Vitrectomy. (time frame: 5-30 minutes, 31-60 minutes, 2-4 hours, 1 day, or 7 days after ocriplasmin injection). 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 NCT01159665, 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 17 Dec 2014; AzTrials last refreshed its copy on 7 Nov 2026.
