Brief summary

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

Detailed description

This study will enroll subjects who have a diagnosis of PD with Hoehn-Yahr stage 1.5-3.0 and assess the impact of low dosage of levodopa/carbidopa/entacapone treatment on the motor function and quality of life among PD patients.

Interventions

On Day 1, subjects will be treated with levodopa/carbidopa/entacapone. Based on previous regimen. The dosage of levodopa/carbidopa/entacapone will be equal to the previous total daily dose of LD, and the frequency of administration of levodopa/carbidopa/entacapone is three or four times a day. Levodopa/carbidopa/entacapone could be titrated in next 2 weeks according to the investigator's judgment, based on individual clinical response and tolerability. After 2-week titration, the dose of levodopa/carbidopa/entacapone will remain as constant as possible to the end of study.

Design outcomes

Primary

MeasureTime frameDescription
Change From Baseline in Unified Parkinson's Disease Rating Scale (UPDRS) III ScoreBaseline, Week 8The UPDRS is a standardized assessment scale used to measure the patient's disease state. UPDRS Part III measures the motor function of the patient. A higher score indicates greater disability.

Secondary

MeasureTime frameDescription
Change From Baseline in UPDRS II ScoreBaseline, Week 8The UPDRS is a standardized assessment scale used to measure the patient's disease state. UPDRS Part II measures the patient's activities of daily living. A higher score indicates greater disability.
Change From Baseline in Health-related Quality of Life Assessed Using the 39-item Parkinson's Disease Questionnaire (PDQ-39)Baseline, Week 8The PDQ-39 instrument is used to assess quality of life in individuals with PD. A lower score indicates better quality of life.
Incidence of dyskinesia and wearing offBaseline, Week 8Dyskinesia and wearing off are common motor complications. A motor complications patient questionnaire will be record.
