Active clinical trials for "Retinal Vein Occlusion"

The purpose of the study is to evaluate the safety and tolerability of a single administration of FOV2302 (ecallantide) in patients with macular edema associated with central retinal vein occlusion.

This is a Phase 1b open-label study to assess the bioactivity, ocular and systemic safety, tolerability, and pharmacokinetics of repeated injections of KSI-301 at two dose levels: 2.5 mg and 5 mg

The aim of this study is to develop a less risky, yet effective and more sustainable treatment for retinal vein occlusions than the current commonly used approach of repeated intravitreal triamcinolone acetonide (Kenalog) injections. The types of retinal vien occlusion that are being studied include central (CVRO), hemi-retinal (HRVO),and branch (BRVO) retinal vein occlusion. Niacin, (Nicotinic Acid, not Nicotinamide) a B-vitamin, has lipid lowering and vasodilating properties. The combination of Niacin and Prednisolone Acetate steroid eye drops as a non-invasive treatment approach was developed by the Principal Investigator. The Niacin dilates the retinal vessels, hopefully encouraging earlier collateral vessel formation aimed at bypassing the venous obstruction, thus restoring venous outflow. The Prednisolone Acetate steroid eye drops are aimed at reducing vascular leakage and therefore the macular edema in the eye while the Niacin is taking effect.

The purpose of this study was to evaluate the efficacy and safety of brolucizumab in treatment of patients with macular edema (ME) secondary to central retinal vein occlusion (CRVO).

This Phase 3, multicenter, randomized, masked, controlled, parallel group study is designed to demonstrate that suprachoroidal (SC) CLS-TA administered with intravitreal (IVT) anti-VEGF agent in subjects with treatment naive RVO is superior to IVT anti-VEGF agent used alone.

Retinal vein occlusion (RVO) is the second commonest retinal disease after diabetic retinopathy, and is a common cause of unilateral visual loss. There are two aims in the management of RVO: the identification of modifiable risk factors and their medical management and the recognition and management of sight-threatening complications. The management of the disease includes laser therapy and the control of systemic associated diseases. Many other treatments have been proposed but there is no evidence on their efficacy in modulating the outcome of branch or central RVO. There are currently no adequate clinical trials that have evaluated the efficacy and safety of antithrombotic agents in this setting. Antiplatelet agents are frequently used in clinical practice. Anticoagulant drugs, either heparins or coumarins, are also used in this setting as they represent the first line therapy for the treatment of venous thromboembolism. Aim of this randomized controlled study is to to compare the efficacy and safety of aspirin and of a low molecular weight heparin, parnaparin, in the treatment of RVO. Study treatment is administered for 3 months. Primary end-point of the study is the incidence of functional worsening of the eye with RVO at 6 months. Secondary efficacy outcomes are the following: proportion of cases requiring laser treatment because of the extension of the ischemic lesion and/or the presence of neovascularisation and/or macular oedema, incidence of recurrent RVO objectively documented by fluorescein angiography. Safety outcomes are defined by the incidence of major and minor bleeding events.

Natural evolution of severe central retinal vein occlusion with low visual acuity is very poor. A randomized clinical trial will compare troxerutin and platelet anti-aggregating agents (drug treatment) versus surgery and drug treatment. Surgery will include vitrectomy and radial optic neurotomy. The primary outcome will be vision measured 6 months after surgery.

To determine if Ozurdex implant can offer an effective treatment for macular edema associated with retinal vein occlusion when treatment with intravitreal Avastin, Lucentis, or Eylea have not demonstrated a significant response.

To provide use of Anecortave Acetate Sterile Suspension of 15mg for a series of five patients with rubeosis iridis. Rubeosis iridis refers to neovascularization of the iris. It is caused by a number of conditions which include, but are not limited to severe diabetic retinopathy, central retinal vein occlusion, chronic inflammation, and infection. Anecortave acetate is an angiostatic, experimental drug that is being tested to prevent the growth of blood vessels under the retina in patients with age-related macular degeneration (AMD). Therefore, it is logical to apply the usage of Anecortave to patient's with rubeosis iridis in order to reduce the neovascularization stimulus and cause the regression of the abnormal iris vessels.

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.
