January 21, 2021 updated by: Christian Baumann

Inhibiting COMT in Parkinson's Disease A Monocenter, Observational, Rater-blinded Trial of Entacapone in Parkinson's Disease

The overall aim of this observational study is to investigate the impact of COMT inhibition on homocysteine metabolism, vascular physiology and correlates of neurodegeneration in PD patients with certain COMT genotype. It is designed to evaluate effect size of Hcy lowering to secondary outcome parameters. Assessment of outcome parameters will be rater-blinded or computer-based.
