Active clinical trials for "Diabetic Retinopathy"

This is a Phase 2a, randomized, single-masked (participant), sham controlled clinical study.

Evaluate the Safety, Tolerability, and Efficacy of OTX-TKI in Subjects with Moderately Severe to Severe Non-proliferative Diabetic Retinopathy

It is estimated that there are about 600 million diabetes mellitus (DM) patients all over the world until 2040，and almost 50% of whom have some degree of diabetic retinopathy (DR) at any given time. About 5% to 10% diabetic retinopathy would develop vision-threatening complications, including proliferative diabetic retinopathy (PDR), capillary non-perfusion, or macular edema. Data from the DRS suggest that given long enough duration of diabetes, approximately 60% of patients with DR will develop PDR, and without intervention, 75% nonproliferative diabetic retinopathy (NPDR) will development PDR within 1 year follow up, 45% will develop high-risk PDR, nearly half of PDR will experience profound visual loss. panretinal photocoagulation (PRP) only reduced 50% risk of sever visual loss and about 25% of the sNPDR patients who finished PRP need Pars-plana vitrectomy (PPV) in a 5 year follow up. Vitreous have been proven to play an important role in the development of NPDR to PDR, which were the collection of vascular endothelial growth factor (VEGF) factors and the major component of proliferative lesion in the later stage of PDR. Micro-invasive Pars-plana vitrectomy has been shown as a safe and effective method in the treatment of PDR, through removing the pathological vitreous, proliferative membrane and also the VEGF factors. However, whether or not Micro-invasive Pars-plana vitrectomy will be more effective than PRP to control the progression of NDPR remained unknown.

RGX-314 is being developed as a novel, potential one-time gene therapy treatment for the treatment of diabetic retinopathy, a chronic and progressive complication of diabetes mellitus. Diabetic retinopathy (DR) is a sight-threatening disease characterized in the early stages by neuronal and vascular dysfunction in the retina, and later by neovascularization that leads to further deterioration of functional vision. Despite the availability of current treatments, diabetic retinopathy remains the leading cause of vision loss in working-age adults, those between the ages of 20 and 74. Existing treatment with anti-VEGF agents, although shown to be effective, are limited by short therapeutic half-lives, which then require frequent intravitreal injections over the patient's lifetime, resulting in increased risk of associated adverse events and significant treatment burden. Due to the burden of treatment, patients often do not closely adhere to treatment regimens and experience sub-optimal outcomes and a decline in vision. RGX-314 is being developed as a potential one time treatment for diabetic retinopathy, which may deliver advantages over conventional treatments, such as potentially providing a longer duration of therapeutic effect and intervening at an earlier stage of the disease.

OPL-0401-201 is a multicenter study to investigate the safety and efficacy of OPL-0401 in patients with diabetes mellitus (DM) with diabetic retinopathy.

Diabetic retinopathy has been found progress in 20-70% diabetic patient after cataract phacoemulsification surgery. Intravitreal injection of anti-VEGF Ranibizumab is an important treatment for diabetic retinopathy including non-proliferative diabetic retinopathy (NPDR). However, there is no research about phacoemulsification surgery combine Intravitreal injection of Ranibizumab on diabetic retinopathy. The research focus on the effect of phacoemulsification surgery combine intravitreal injection of Ranibizumab on mild non-proliferative diabetic retinopathy and explore the reasons for differences in treatment outcomes.

This clinical trial is a multi-center, double-blind, randomized, placebo controlled , parallel design, superiority, phase 4 study to evaluate the efficacy and safety of Entelon 50mg in 396 patients with non-proliferative diabetic retinopathy.

Diabetic retinopathy (DR) is one of the main complications in diabetes, the proliferative diabetic retinopathy (PDR) is the most important one of the reasons leading to decreased vision, PDR is the stage of clinical intervention. Pars plana vitrectomy (PPV) is an effective treatment for PDR, while vitreous haemorrhage (VH) is a common complication after PPV, with incidence ranging from 11.8% to 75%, and is the main cause of reoperation. Anti-Vascular endothelial growth factor (VEGF) therapy for vitreous hemorrhage can inhibit neovascularization and prevent recurrent vitreous haemorrhage after absorption. Previous studies have found that anti-VEGF is a safe and effective treatment for postoperative recurrent VH. In consideration of the psychological and economic factor of patients, this study intends to observe the effectiveness of single vitreous injection of Ranibizumab in the treatment of postoperative recurrent VH on the basis of previous clinical work. Compare the visual acuity, macular thickness, VH recurrence and patient satisfaction between the Ranibizumab group and the PPV group by randomized grouping.To observe the effective rate and clearance time of recurrent VH after Ranibizumab treatment and whether it can effectively reduce the rate of PPV. To provide clinical guidance for the precise treatment of PDR patients, the treatment of PDR patients has important clinical significance and social and economic significance.
