Active clinical trials for "Macular Degeneration"

Investigate the Safety, Pharmacokinetics, and Treatment effects of Single and Multi-dose of Intravitreal AVD-104 in participants with geographic atrophy secondary to age-related macular degeneration.

The goal of this clinical trial is to evaluate effects of consecutive Yellow and Red Light Emitting Diode photobiomodulation in dry age-related macular degeneration (AMD). The main questions it aims to answer are: Is Yellow and Red Light Emitting Diode photobiomodulation effective in decreasing drusen volume in patients affected by dry AMD? Does Yellow and Red Light Emitting Diode photobiomodulation increase visual acuity and contrast sensitivity in patients affected by dry AMD? Participants will be randomly assigned to a treatment or a sham group. Treatment consists in two cycles with two phases each: 1st phase: 300 seconds of continuous Yellow light with eyes closed + 60 seconds of pulsed Yellow light with eyes opened; 2d phase: 300 seconds of continuous Red light with eyes closed + 60 seconds of pulsed Red light with eyes opened. Cycle 1 consists of 8 sessions (two PBM per week for 4 weeks) and cycle 2 consists of 6 sessions (two PBM per week for 3 weeks). Researchers will compare patients in the treatment group to those in the sham group to evaluate differences in objective signs and subjective symptoms of dry AMD.

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.

The main objective of the study is evaluation of the safety and tolerability of RPESC-RPE-4W as therapy for dry AMD.

interventional trial for off label use of high dose atorvastatin 80 mg in intermediate AMD patients and correlate recovery response measured by dark adaptation recovery time with drusen volume reduction measured by SD-OCT

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).

A Study to Evaluate the Safety, Tolerability and Pharmacokinetics of D-4517.2 After Subcutaneous Administration in subjects with Neovascular (wet) Age-Related Macular Degeneration (AMD) or subjects with Diabetic Macular Edema (DME)

Phase 1/2 dose-escalation and randomized, controlled, masked expansion trial in adults with wet AMD undergoing active anti-VEGF treatment

The purpose of this study is to compare the efficacy and safety of MW02 versus Lucentis in the treatment of neovascular age-related macular degeneration.The study was divided into two stages. The first stage was to explore the dose and the second stage was to explore the frequency of administration.
