Trial summary

The purpose of this study is to determine if additional panretinal photocoagulation of ischemic areas following retinal vein occlusion (RVO) may reduce the rate of recurrence and allow longer treatment intervals in anti-Vascular Endothelial Growth Factor (VEGF) treatment following the "trea-and-extend" scheme.

About this study

The purpose of this study is to determine if additional panretinal photocoagulation of ischemic areas following retinal vein occlusion (RVO) may reduce the rate of recurrence and allow longer treatment intervals in anti-Vascular Endothelial Growth Factor (VEGF) treatment following the "trea-and-extend" scheme.

Read the detailed description

Patients with macular edema following RVO receive an anti-VEGF treatment by injection of Ranibizumab for 12 months in the "treat-and-extend" scheme. Following this scheme, all patients receive a series of three injections at the interval of 4 weeks. Thereafter, the retreatment interval is determined by results of certain examinations.

The next control including a reinjection is scheduled with an extension of one week until the patient presents signs of recurrence. Assuming that by the time of recurrence the interval is too long, the next control (following a retreatment) is then scheduled one week sooner than the last control. Following this treatment schedule, the individualized retreatment interval is thereafter kept steady.

Half the patients receive an additional panretinal photocoagulation on visit 3 and / or 4. Aim of this study is to investigate if this additional panretinal photocoagulation may result in a longer individualized retreatment interval corresponding to a reduced rate of recurrence of macular edema.

What is being measured

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

  1. Differences in the length of the treatment-free interval in patients with or without panretinal photocoagulation

    Length of the longest interval between reinjections that did not result in recurrence

    Measured: within 12 months after first injection of Ranibizumab

Secondary outcomes (4)
  1. Number of Injections

    Measured: within 12 months after first injection of Ranibizumab

  2. Retinal thickness in µm measured by spectral domain (SD)-Optical coherence tomography (OCT) at end-of-study visit

    end-of-study visit is performed at individualized retreatment interval (can range from 4-9 weeks) after last injection within 12 months after first injection of Ranibizumab

    Measured: 4-9 weeks after last injection within

  3. Visus at end-of-study visit

    end-of-study visit is performed at individualized retreatment interval (can range from 4-9 weeks) after last injection within 12 months after first injection of Ranibizumab

    Measured: 4-9 weeks after last injection within

  4. Percentage of patients with retinal thickness of more than 220 µm in the OCT examination at the end-of-study visit

    end-of-study visit is performed at individualized retreatment interval (can range from 4-9 weeks) after last injection within 12 months after first injection of Ranibizumab

    Measured: 4-9 weeks after last injection within

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ranibizumab and Laser in people with Central Retinal Vein Occlusion With Macular Edema, run by PD. Dr. med. Armin Wolf.

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 8 inclusion and 18 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: status not confirmed, as of the sponsor's last update on 13 Aug 2015. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Verena Dykstra, Dr. (+49 228 287 16360, verena.dykstra@ukb.uni-bonn.de), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Differences in the length of the treatment-free interval in patients with or without panretinal photocoagulation (time frame: within 12 months after first injection of Ranibizumab). 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 13 Aug 2015.
