About this study

Official title: A Randomized Trial Comparing Intravitreal Ranibizumab and Macular Laser Photocoagulation for the Treatment of Macular Edema Following Branch Retinal Vein Occlusion

This study is designed to evaluate the efficacy of intravitreal Ranibizumab in comparison with macular laser photocoagulation as treatments for macular edema secondary to branch retinal vein occlusion.

Characteristics of this study is as below

  1. Multicenter, randomized clinical trial. (intravitreal Ranibizumab 0.5mg injection vs. macular laser photocoagulation)
  2. After 48 weeks follow up, functional change(visual acuity)and anatomical change (central retinal thickness) would be evaluated
Being tested
Ranibizumab, macular laser photocoagulation
Keywords
Branch retinal vein occlusion, macular edema, intravitreal injection, ranibizumab
Medical subject headings

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • RanibizumabDrug

    Ranibizumab 0.5mg Ranibizumab will be administered to patients as multiple intravitreal injections.

  • macular laser photocoagulationProcedure or surgery

    Treatment may include both focal and grid therapy using the laser and contact lens of the investigator's choice.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Ranibizumab and macular laser photocoagulation in people with Branch Retinal Vein Occlusion, run by Seoul Retina Investigator Group at 1 site in South Korea.

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 6 inclusion and 8 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 26 Aug 2010. 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 South Korea. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 Song Ee Chung, M.D. (songee129@hanmail.net), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Best Corrected Visual Acuity (ETDRS letters) (time frame: 48 weeks). 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 26 Aug 2010.
