About this study

Official title: Different Regimens of Ranibizumab Treatment for Macular Edema Secondary to Retinal Vein Occlusion: a Randomized and Controlled Clinical Study.

Retinal vein occlusion (RVO) may lead to series of complications including retinal ischemia, macular edema (ME) and induce vision impairment. Intravitreal injection of Ranibizumab (0.5mg) has been proved to be a safe and effective method for the treatment of RVO-ME. In this study, different treatment regimens of Ranibizumab is applied and the effects is observed at 1-6 months to explore the best regimen for RVO. After 6 months, anti-VEGF therapy and/or laser photocoagulation is used to explore whether laser photocoagulation can maintain the therapeutic effect of Ranibizumab or reduce the injection number.

Read the detailed description

Retinal vein occlusion (RVO) may lead to series of complications including retinal ischemia, macular edema (ME) and so on. Retinal vein occlusion (RVO) can be classified as branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO). Retinal vein occlusion with macular edema (RVO-ME) is the main cause of RVO induced vision impairment. Intravitreal injection of Ranibizumab (0.5mg) has been proved to be a safe and effective method for the treatment of RVO-ME. Although multiple injections of anti-vascular endothelial growth factor (anti-VEGF) drugs are beneficial to the therapeutic results of RVO-ME, they may also increase the risk of systemic or ocular complications and at the same time increase the economic burden of patients to a certain extent. Different studies have shown that anti-VEGF therapy with low frequency injection (2-5 doses) is also effective for RVO-related ME. However, there are still different views on which option is better. Meanwhile, the effect of laser photocoagulation in the non-perfusion area of the retina, and whether the number of subsequent anti-VEGF injections can be reduced accordingly, is still uncertain. Therefore, in this study, different treatment regimens will be applied and the effects will be observed at 1-6 months. After 6 months, anti-VEGF therapy and/or laser photocoagulation will be used to explore whether laser photocoagulation can maintain the therapeutic effect or reduce the injection number of Ranibizumab. This study intends to explore the therapeutic effects of different treatment regimens on RVO-ME, and meanwhile to investigate the dynamic changes in retinal morphology, microcirculation and visual function during RVO treatment by means of angiography-optical coherence tomography (angio-OCT), microperimetry, electroretinogram (ERG) examination and other methods.

What participants receive

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

  • RanibizumabDrug

    Also called Lucentis

    Patients will receive intravitreal injection of Ranibizumab 0.5 mg (1+PRN or 3+PRN) according to the study until month 6. Then, patients will received Ranibizumab PRN only or laser photocoagulation with Ranibizumab PRN after month 6.

  • laser photocoagulationDevice

    After month 6, patients will received Ranibizumab PRN only or laser photocoagulation with Ranibizumab PRN according the re-randomization at month 6.

Study groups in NCT04062370
Study groupRoleWhat they receive
1+PRNExperimentalIntravitreal injection of Ranibizumab 0.5 mg (IVR): initial injection for 1 time ( month 1), and then IVR is required if central macular thickness (CMT) greater than 300 μm during the follow-up observation (Pro re nata, PRN, means if necessary). After 6 months follow-up, patients in this arm will be randomly divided to receive IVR PRN only or laser photocoagulation combined with IVR PRN. IVR PRN only: patient will receive IVR PRN if CMT greater than 300 μm during the follow-up observation (PRN) after month 6. Laser photocoagulation with IVR PRN: patient will receive laser photocoagulation for non-perfusion area according to FFA results after month 6, and then received IVR PRN if CMT greater than 300 μm.
Receives: Drug: Ranibizumab; Device: laser photocoagulation
3+PRNActive comparatorIntravitreal injection of Ranibizumab 0.5 mg (IVR): initial injection for 3 consecutive times ( months 1, 2 and 3 ),and then IVR is required if CMT greater than 300 μm during the follow-up observation (PRN). After 6 months follow-up, patients in this arm will be randomly divided to receive IVR PRN only or laser photocoagulation combined with IVR PRN. IVR PRN only: patient will receive IVR PRN if CMT greater than 300 μm during the follow-up observation (PRN) after month 6. Laser photocoagulation with IVR PRN: patient will receive laser photocoagulation for non-perfusion area according to FFA results after month 6, and then received IVR PRN if CMT greater than 300 μm.
