NCT02605434

Brief Summary

The purpose of this study is to determine whether the gastric retentive Accordion Pill™ Carbidopa/Levodopa (AP-CD/LD) is more effective than the commercially available immediate release Carbidopa/Levodopa in reducing motor fluctuations such as "off time" in advanced Parkinson's Disease patients.

Outcome Measures

Primary Outcomes (1)

  • Change from Baseline through study completion, an average of 27 weeks, in the percentage of daily "Off time" during waking hours

    Change from Baseline through study completion, an average of 27 weeks, in the percentage of daily "Off time" during waking hours based on Hauser Home Diary assessments; Total number of "Off " hours normalized to a 16- hour waking day will also be calculated but only a single p-value applicable to both the percentage and hours will be reported.

    Baseline through study completion, an average of 27 weeks

Secondary Outcomes (4)

  • Change from Baseline through study completion, an average of 27 weeks, in "On time" without troublesome dyskinesia during waking hours

    Baseline through study completion, an average of 27 weeks

  • Change in the number of total daily LD doses from Baseline through study completion, an average of 27 weeks (hours)

    Baseline through study completion, an average of 27 weeks

  • CGI-I through study completion, an average of 27 weeks, as recorded by physician & patient

    Baseline through through study completion, an average of 27 weeks,

  • Change from Baseline through study completion, an average of 27 weeks, in total UPDRS Score (Sum of Parts I-III)

    Baseline through study completion, an average of 27 weeks
