A Study to Evaluate Fixed Dose Carbidopa/Levodopa/Entacapone Versus Immediate Release Carbidopa/Levodopa

Phase 3
Completed
Conditions
Parkinson's Disease
Registration Number
NCT00134966
Lead Sponsor
Novartis
Brief Summary

The purpose of this study is to achieve approval for the use of carbidopa/levodopa/entacapone in early Parkinson's disease (PD) by demonstrating that when used as initial levodopa therapy in early PD, carbidopa/levodopa/entacapone provides significantly greater symptomatic benefit than immediate release carbidopa/levodopa administered at the same levodopa dosage level of 100 mg three times a day (t.i.d.).
