Information provided by (Responsible Party):
Novartis
  Purpose
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.).

Condition Intervention Phase
Parkinson's Disease Drug: capsules containing: carbidopa (25 mg), levodopa (100 mg), entacapone (200 mg) Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A 39 Week Randomized, Double-Blind, Parallel Group, Multicenter Study to Evaluate the Effect of Fixed Dose Carbidopa/Levodopa/Entacapone 100 mg t.i.d. vs. Immediate Release Carbidopa/Levodopa 25/100 mg (t.i.d.) in Parkinson's Disease Patients Requiring Levodopa
