Active clinical trials for "Retinal Vein Occlusion"

The purpose of this study is to verify the efficacy and safety of intravitreal injection of conbercept in patients with macular edema (ME) caused by branch retinal vein occlusion (BRVO).

This study evaluates the efficacy and safety of Conbercept ophthalmic injection. This is a multi-center, randomized, double-masked, placebo-controlled phase III clinical study. 237 patients with central retinal vein occlusion(CRVO) are expected to be enrolled in the study and randomly assigned into the Conbercept ophthalmic injection treatment group or the control group at a ratio of 2:1.

A phase 2, multicenter, randomized, active-controlled, masked, parallel arm study designed to evaluate the safety and efficacy of a single suprachoroidal injection of CLS-TA, triamcinolone acetonide injectable suspension, given along with an intravitreal (IVT) injection of aflibercept compared to IVT aflibercept alone in subjects with retinal vein occlusion (RVO).

Phase 2a open-label study to assess the efficacy and safety of subcutaneous 15mg AKB-9778 administered twice daily for 84 days in subjects with macular edema due to RVO.

The primary objectives of the study are to evaluate the safety and effect of KPI-121 0.25% ophthalmic suspension and KPI-121 1.0% ophthalmic suspension on intraretinal or subretinal fluid secondary to Retinal Vein Occlusion or Diabetic Macular Edema.

The investigators have worked with software designers to develop a software that allows us to analyse current adherence to guidelines on Ophthalmic conditions such as Age related Macular Degeneration (AMD), Diabetic Macular Edema (DMO) and Retinal vein occlusion (RVO). National guidelines state that those patients with fluid accumulation in their central macular, meeting criteria, are eligible for injections into the vitreous cavity of the eye (intravitreal).(1) As these condition are common the trial is relevant to the public and patients as future management may be affected by the outcomes of this trial. The investigators will trial the software which uses Artificial Intelligence (AI) algorithms to determine the most suitable review required for patients being managed in clinics, based on 'Vision' and 'Retinal Thickness' demographics. This will be done prospectively, in real time. The question to be addressed is 'Can medical and non-medical practitioners accurately determine treatment and follow-up for patients assisted by an AI clinical decision support system, for the three most common chronic macular diseases - Wet Age-Related Macular Degeneration (wAMD), Diabetic Macular Oedema (DMO) and Retinal Vein Occlusion (RVO) - in a safe and clinically cost effective way?' Patients undergoing treatment for at least 12 months are eligible to participate, so long as they are able to provide consent for their data to be used. Participants will have no change to their care during the trial. The study, will take place at Guy's and St. Thomas' NHS FT (GSTT) from where participants will be recruited, and will last approximately 6 months of data collection. The software will be used by the research Fellow, alongside the masked consultant. Therefore the patient pathway and management will not be impacted by this trial. Patients will be consented for data use.

To compare the effect of intravitreal-Bevacizumab and Triamcinolone with intravitreal-Bevacizumab alone on visual acuity and central foveal thickness in patients with macular edema secondary to central retinal vein occlusion.

Primary Objective: To investigate the pretreatment quantitative factors as shown in SD-OCT images that correlate with posttreatment VA in patients who underwent intravitreal Lucentis (Ranibizumab) for RVO. Secondary Objectives: Correlations between posttreatment BCVA and pretreatment factors were evaluated, including age, pretreatment BCVA, photoreceptor outer segment (PROS) length, central foveal thickness (CFT), outer foveal thickness (OFT), and outer nuclear layer thickness (ONLT). The factors influencing posttreatment BCVA were evaluated using multiple regression analysis. Detailed information on macular morphology, such as the photoreceptor IS/OS junction and ELM, can be obtained in SD-OCT. Some OCT studies evaluated other quantitative factors in eye disease. It was reported that PROS length was correlated with BCVA in patients with DME.¹ Other investigators suggested that the thickness, area, and volume of the outer layer were correlated with BCVA in patients with dry age-related macular degeneration (AMD).² Outer foveal thickness (OFT) and relative reflectivity of the outer nuclear layer (ONL) were associated with BCVA in patients with macular hole.3, 4 The volume of the ONL was found to be associated with BCVA in patients with AMD.5 The aim of this study was to investigate the pretreatment quantitative factors as shown in SD-OCT images that correlate with posttreatment VA in patients who underwent intravitreal Lucentis (Ranibizumab) for RVO.

SCORE2 is a multicenter, prospective, randomized, phase III clinical trial in which all participants enrolled will be followed for up to 2.5 years. SCORE2 is designed as a non-inferiority trial, with study eyes randomized to intravitreal bevacizumab (1.25 mg) every 4 weeks vs. intravitreal aflibercept (2.0 mg) every 4 weeks. SCORE2 aims to determine if bevacizumab is non-inferior to aflibercept for the treatment of macular edema associated with central retinal vein occlusion (CRVO), with the primary outcome of visual acuity measured at Month 6.

This study will generate comparative data for 0.5-mg ranibizumab using PRN dosing administered with or without adjunctive laser treatment versus laser photocoagulation (the current standard of care) up to Month 6 in patients with visual impairment due to ME secondary to BRVO. Additionally the results of this study will provide long-term (24-month) safety and efficacy data for ranibizumab, administered with or without adjunctive laser treatment in this indication.
