Trial Outcomes & Findings for Study in Advanced Parkinson's Disease Patients With Predictable Motor Fluctuations (NCT NCT01515410)

NCT ID: NCT01515410

Last Updated: 2014-03-10

Results Overview

"OFF" indicates wearing off motor fluctuations before the next levodopa dose. Percent "OFF" time is calculated as the total "OFF" time divided by the total awake time for each day and multiplied by 100. Patient diary-every 30min while awake for 3days prior to initial Day1 as baseline \& during the last 3days before Day10 for both treatments for dyskinesia state. Baseline is the average of the 3 days recorded in the patient diary prior to Day 1 of Period 1. End of Period is the average of the 3 days recorded in the patient diary prior to Day 10 in each period. Clinician-Assess efficacy at pre-dose, every 30min for Day1 and hourly for Day10 for dyskinesia state \& motor fluctuations at clinic visits.

Participant Flow

A total of 34 subjects were randomly assigned to treatment in this crossover study: 19 in the DM-1992 for Period 1 and Sinemet IR for Period 2 sequence, and 15 in the Sinemet IR for Period 1 and DM-1992 for Period 2 sequence. All 34 subjects received study treatment and were included in the safety and intent-to-treat (ITT) populations.

PRIMARY outcome

Timeframe: Baseline and 10 days for each of the 2 study periods

Population: Modified Intent-to-treat (ITT) Population

"OFF" indicates wearing off motor fluctuations before the next levodopa dose. Percent "OFF" time is calculated as the total "OFF" time divided by the total awake time for each day and multiplied by 100. Patient diary-every 30min while awake for 3days prior to initial Day1 as baseline \& during the last 3days before Day10 for both treatments for dyskinesia state. Baseline is the average of the 3 days recorded in the patient diary prior to Day 1 of Period 1. End of Period is the average of the 3 days recorded in the patient diary prior to Day 10 in each period. Clinician-Assess efficacy at pre-dose, every 30min for Day1 and hourly for Day10 for dyskinesia state \& motor fluctuations at clinic visits.
