Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00099268 ↗	Efficacy and Safety of Carbidopa/Levodopa/Entacapone in Patients With Parkinson's Disease Requiring Initiation of Levodopa Therapy	Completed	Orion Corporation, Orion Pharma	Phase 3	2004-09-01	The CELC200A2401 study has been designed in order to evaluate the hypothesis that administering the combination carbidopa/levodopa/entacapone at the time that levodopa therapy is initiated results in a decrease in the risk of the development of motor complications for patients with Parkinson's disease.
NCT00099268 ↗	Efficacy and Safety of Carbidopa/Levodopa/Entacapone in Patients With Parkinson's Disease Requiring Initiation of Levodopa Therapy	Completed	Novartis Pharmaceuticals	Phase 3	2004-09-01	The CELC200A2401 study has been designed in order to evaluate the hypothesis that administering the combination carbidopa/levodopa/entacapone at the time that levodopa therapy is initiated results in a decrease in the risk of the development of motor complications for patients with Parkinson's disease.
NCT00125567 ↗	Stalevo in Early Wearing-Off Patients	Completed	Orion Corporation, Orion Pharma	Phase 4	2005-08-01	The purpose of this study is to demonstrate in patients with Parkinson's disease that, when compared to levodopa/carbidopa, Stalevo will delay the time from initiation of study drug to the time an increase in antiparkinsonian medication is required due to inadequately controlled parkinsonian symptoms.
NCT00134966 ↗	A Study to Evaluate Fixed Dose Carbidopa/Levodopa/Entacapone Versus Immediate Release Carbidopa/Levodopa	Completed	Novartis	Phase 3	2005-08-01	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.).
