Official title
Pilot Study of L-DOPA Safety and Tolerability in Patients With AMD, and Proof of Concept That L-DOPA Improves Surrogate Biomarkers in Patients With Moderate to Advanced AMD
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
From 3 large patient databases, patients diagnosed with AMD who have never taken levodopa(L-DOPA) containing medications have a mean age of diagnosis at 71 years. Patients who have been treated with L-DOPA containing medications have a mean age of diagnosis of AMD at 79 years. L-DOPA binds to GPR143 in the retinal pigment epithelium, and releases PEDF, which protects the retina and downregulates VEGF, which is the cause of neovascularization. The Investigators will evaluate the safety and tolerability of carbidopa-levodopa in patients with AMD, and measure the effects on surrogate functional biomarkers of AMD.
