Summary: This observational, multicenter, case-control study aims to evaluate the efficacy and safety of Entacapone combined with Madopar (levodopa/benserazide) in the treatment of early-stage Parkinson's disease (PD) among Chinese patients. The study will enroll patients diagnosed with PD according to the MDS criteria, aged 18-80, with modified Hoehn-Yahr stages 1-2.5, and who have not previously used Ent...

Summary: Alpha-synucleinopathies refer to age-related neurodegenerative and dementing disorders, characterized by the accumulation of alpha-synuclein in neurons and/or glia. The anatomical location of alpha-synuclein inclusions (Lewy Bodies) and the pattern of progressive neuronal death (e.g. caudal to rostral brainstem) give rise to distinct neurological phenotypes, including Parkinson's disease (PD), Mul...

Summary: This is a, open-label, single-arm 8-week investigation of levodopa/carbidopa/entacapone in the treatment of early Parkinson's disease.
