Active clinical trials for "Wet Macular Degeneration"

Wet (or neovascular) form of age-related macular degeneration (wAMD) is the most common cause of blindness in the Western world. Currently, anti-vascular endothelial growth factor (VEGF) intravitreal injections (IVI) remain the standard-of-care treatment for wAMD. Previous studies show that about 90% of treated patients lose minimal visual function after 2 years of follow-up. There is still, a subset of 15% patients, incomplete responders, that do not improve and possibly worsen due to the persistence of sub-retinal fluid (with or without intra-retinal fluid) with chronic treatment. The investigators plan to evaluate the effect of oral doxycycline versus placebo on the anatomic and functional outcomes in persistent sub-retinal eye fluid in neovascular wet age-related macular degeneration. This subset are incomplete or non-responders to current anti-VEGF intravitreal therapy.

RGX-314 is being developed as a potential novel one-time gene therapy treatment for the treatment of neovascular (wet) age related macular degeneration (wet AMD). Wet AMD is characterized by loss of vision due to new, leaky blood vessel formation in the retina. Wet AMD is a significant cause of vision loss in the United States, Europe and Japan, with up to 2 million people living with wet AMD in these geographies alone. Current anti-VEGF therapies have significantly changed the landscape for treatment of wet AMD, becoming the standard of care due to their ability to prevent progression of vision loss in the majority of patients. These therapies, however, require life-long intraocular injections, typically repeated every four to twelve weeks in frequency, to maintain efficacy. Due to the burden of treatment, patients often experience a decline in vision with reduced frequency of treatment over time.

Age-related macular degeneration (AMD) is a progressive disease leading to severe and irreversible vision loss of which the neovascular AMD (nAMD) accounted for 90% blindness in AMD. nAMD is primarily driven by the perturbation of vascular endothelial growth factor (VEGF). VEGF overexpression leads to abnormal growth of choroidal neovascularization (CNV), which is a hallmark of AMD. Although anti-VEGF agents are effective in treating nAMD, long-term efficacy decreases over time due to the need for repeated injections impacting patient compliance with treatment regimen while patients still may lose vision during the 7th or 8th year of treatment. These frequent intravitreal injections can increase the risk of complications, including submacular hemorrhage, intraocular hypertension, inflammation, and retinal detachment. Furthermore, there are up to 46% of nAMD patients using anti-VEGF agents who have shown poor response or have developed tachyphylaxis with anti-VEGF therapies. HG202 is a CRISPR/Cas13 RNA-editing therapy packaging novel high-fidelity Cas13 technology using one single AAV vector to partially knock-down the expression of VEGFA and thus inhibit CNV formation in AMD patients who are either responsive or non-responsive to anti-VEGF agents. The long-term, stable delivery of HG202 following a one (1) time gene-editing therapy treatment for nAMD could potentially reduce the frequent injection treatment burden of currently available therapies AND treat nAMD patients who are non-responsive to anti-VEGF therapies and have no treatment.

Optical Coherent Tomography Angiography (OCTA)-Directed PDT Triple Therapy for Treatment-Naïve Patients with Exudative Age-related Macular Degeneration (ARMD) versus Standard of Care Anti-VEGF Monotherapy

This study is a randomized, multi-center, double blind, Lucentis controlled non-inferiority study in neovascular age-related macular degeneration patients. The objective of this study is to compare the efficacy and safety of TAB014 and ranibizumab (Lucentis).

To determine safety, pharmacokinetics, and duration of effect of periocularly administered AIV007 gel suspension in subjects with neovascular age-related macular degeneration (nAMD) or diabetic macular edema (DME).

Study purpose: To evaluate if previously high-frequent (3-5 weekly) aflibercept treated neovascular age-related macular degeneration (nAMD) can be extended in their treatment interval when switched to faricimab. Primary objective: To assess the efficacy of faricimab compared to aflibercept in terms of durability at 32 weeks by extending treatment interval in previous high-frequent aflibercept treated nAMD.

Study ML43000 is a Phase IV multicenter, open-label (BCVA assessor-masked) study designed to assess the response to treatment with SUSVIMO Q24W in patients with nAMD who have been previously treated with anti-VEGF agents other than ranibizumab. The substudy will evaluate the impact on corneal endothelial cells with SUSVIMO refilled every 24 weeks (Q24W) in patients with neovascular age-related macular degeneration (nAMD).

A 2-year phase 3, multicentre, randomised, parallel-group, sham-controlled, double-masked study. Primary efficacy will be determined at Week 52.

Study WR42221 is a Phase IIIb, global, multicenter, randomized, visual assessor-masked study designed to assess the efficacy, safety, and pharmacokinetics of the Port Delivery System with ranibizumab (PDS) 100 mg/mL delivered every 36 weeks (Q36W) compared with every 24 weeks (Q24W) in patients with neovascular age-related macular degeneration (nAMD).
