Active clinical trials for "Diabetic Retinopathy"

To evaluate the effectiveness of study drug in improving visual acuity compared to laser treatment in the patients with diabetic macular edema

The purpose of this study is to determine if treatment with infliximab improves macular edema which is refractory to laser photocoagulation in patients with diabetes.

To identify biomarkers, obtained using non-invasive procedures, that can predict disease progression and progression to sight-threatening stages of the disease and to characterize the retinal changes that occur in Non Proliferative Diabetic Retinopathy (NPDR).

The pilot study evaluates the efficacy and safety of Canakinumab (ILARIS®) in subjects with proliferative diabetic retinopathy secondary to type 1 and 2 diabetes. Ten subjects will be enrolled to receive 150 mg Canakinumab (ILARIS®) by subcutaneous injection. Beginning on day 0, each subject will receive a subcutaneous injection of study drug every 8 weeks for 16 weeks, a total of 3 injections. All subjects will undergo regular follow-up assessments every 8 weeks through 24 weeks. Fluorescein angiography (FA) is repeated every 8 weeks. In case of progression of retinal neovascularization on FA panretinal laser photocoagulation is administered as rescue therapy. The primary outcome is the regression of retinal neovascularizations (NVE and NVD) in FA at 24 weeks. In addition to key secondary outcomes including regression of diabetic macular edema, change in best-corrected visual acuity, change in HbA1c levels and change in markers of systemic inflammation. Safety will be assessed by measurements of vital signs, clinical laboratory assessments, and the recording of adverse clinical events.

The purpose of this study is to assess the efficacy and safety of up to 3 intravitreal injections of ocriplasmin (0.0625mg or 0.125mg), in subjects with moderate to very severe non-proliferative diabetic retinopathy (NPDR), to induce total posterior vitreous detachment (PVD) in order to reduce the risk of disease progression to proliferative diabetic retinopathy (PDR).

Phase III study comparing monthly octreotide i.m. in comparison to no additional treatment in patients with proliferative diabetic retinopathy after lasercoagulation.

The Early Treatment Diabetic Retinopathy Study (ETDRS) group founded guidelines for treating patients with clinically significant diabetic macular edema (DME) with focal/grid macular laser photocoagulation. Since then, macular laser, and steroids, were the main therapies for the treatment of DME until anti-vascular endothelial growth factors (anti-VEGF) drugs were developed after a growing body of scientific evidence implicated VEGF in the pathophysiologic process of DME. Anti-VEGF drugs have been implicated in the treatment of DME. VEGF has been shown to play an important role in the occurrence of increased vascular permeability in DME. VEGF levels are significantly higher in patients with DME and extensive leakage than in patients with minimal leakage. Many studies such as Diabetic Retinopathy Clinical Research [DRCR] Network studies, RESTORE Study, RISE and RIDE Research Group, and The BOLT Study have supported the use of anti-VEGF agents in the treatment of DME with better visual outcomes using anti-VEGF injections alone or in combination with other treatments. Several ocular complications of intravitreal anti-VEGF injections have been reported including endophthalmitis, cataract, and retinal detachment. The different effects on macular perfusion between different anti-VEGFs have yet to be fully concluded with mixed conclusions that it increases or decreases or has no effect on perfusion of the macula in response to Anti-VEGF treatment. In many of these studies, however, patients with more ischemic retinas were not included. Retinal ischemia is a vital factor determining the diabetic retinopathy progression and prognosis. Optical coherence tomography angiography (OCTA) detects blood flow by analyzing signal decorrelation between two sequential OCT cross-sectional scans at the same location. As it detects the movements of red blood corpuscles within the vessels, compared to the stationary retinal surroundings, which will result in signal disparity and imaging The split-spectrum amplitude-decorrelation angiography (SSADA) algorithm improves the signal to noise ratio. OCTA is considered a reliable tool in the detection and quantification of macular ischemia in diabetics. In this study, the investigators aim to compare the effect of repeated intravitreal injections of ranibizumab and bevacizumab on the perfusion of different capillary layers in the macula of diabetic patients using OCTA.

This study is conducted to select the THR-687 dose level (Part A of the study) and to assess the efficacy and safety of the selected dose level compared to aflibercept (Part B of the study).

The PROTECT2 pilot study is a single cohort prospective study to gather pilot data and finalize operational details of the main study. The PROTECT2 main study is a prospective randomized controlled multi-center three group clinical trial. The primary endpoint is the percentage of participants in each study group obtaining a qualified eye examination within 12 months of their enrollment in the study.

This multicenter, open-label extension study will evaluate the long-term tolerability and safety for patients completing study CSMS995 0802. During this extension study, all patients will receive open-label treatment of octreotide acetate in microspheres every 4 weeks for 2 years for the treatment of moderately severe to severe NPDR and low risk PDR.
