Brief Summary

The main goal of PD research is to develop disease-modifying drugs to delay or prevent the underlying neurodegenerative process. Levodopa, as the gold standard for PD treatment, is associated with the occurrence of motor complications. Many previous studies have confirmed that Stalevo can reduce the side effects of levodopa alone. Moreover, the effects of Stalevo on the treatment of PD patients have been extensively studied, but the efficacy of Stalevo in early PD patients has been less studied. Therefore, it is necessary to further study the treatment of early PD with Stalevo, and observe whether increasing the number of medication can reduce the occurrence of dyskinesis. The research results will help to deepen the understanding of Stalevo in the treatment of early PD and its clinical efficacy.

Outcome Measures

Primary Outcomes (3)

  • The occurrence and frequency of dyskinesia of participants in two groups were assessed by blind method.

    The duration of the study is 96 weeks. Follow-up: Baseline, 4 weeks, 8 weeks, 12 weeks, 24 weeks, 36 weeks, 48 weeks, 60 weeks, 72 weeks, 84 weeks, 96 weeks. At each visit, the doctor performs a blind assessment of dyskinesia. The proportion of patients with no dyskinesias in the two groups at each visit was recorded. The Kaplan-Meier line was used to analyze the relationship between the drug and the occurrence of dyskinesia.

    1 year

  • The Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) of participants in two groups were assessed by blind method.

    At each visit, the patient completed the MDS-UPDRS. The doctor performs a blind assessment of MDS-UPDRS parts II, III, and IV. MDS-UPDRS part II, Motor Experiences of Daily Living (13 items); part III, Motor Examination (33 items); and part IV, Motor Complications. (6 items). All items have five response options with uniform anchors of 0 = normal, 1 = slight, 2 = mild, 3 = moderate, and 4 = severe. The more severe the symptoms, the higher the score.

    1 year

  • The 9-Item Wearing-Off Questionnaire (WOQ-9) score of participants in two groups were assessed by blind method.

    During the double-blind period, subjects completed WOQ-9 at each visit. WOQ-9 was used to assess symptoms of wearing-off. The nine symptoms include tremor, anxiety, mood changes, slowness of movement, reduced dexterity, general stiffness, pain/aching, slowness of thinking , and muscle cramping. The presence of one of these symptoms and relief after the next dose is indicative of wearing-off.

Study Arms (2)

Stalevo group

EXPERIMENTAL

Stalevo is taken five times a day, three hours apart. Compare the incidence of dyskinesia.

Drug: Stalevo

Control group

ACTIVE COMPARATOR

Carbidopa and Levodopa Sustained-release Tablets is taken five times a day, three hours apart. Compare the incidence of dyskinesia.

Drug: Carbidopa and Levodopa Controlled Release Tablets

Interventions

The dose of Stalevo initially ranges from (Levodopa/Carbidopa/Entacapone) 50/12.5/200 mg 3 times a day to a target dose of 100/25/200 mg 5 times a day, with an interval of 3 hours. No other anti-Parkinson's disease drugs are added.
