Trial Outcomes & Findings for Carbidopa/Levodopa/Entacapone Versus Immediate Release (IR) Carbidopa/Levodopa on Non-motor Symptoms in Patients With Idiopathic Parkinson's Disease and Demonstrating Non-motor Symptoms of Wearing Off (NCT NCT00642356)

NCT ID: NCT00642356

Last Updated: 2011-02-18

Results Overview

The QWOQ-9 is a self-rated questionnaire used to assess motor and non-motor symptoms of Parkinson's disease. The 4 non-motor symptoms are each measured on a five item (0-4) Likert scale, reflecting the severity of the item from "not present" to "very severe". The range of possible score values of the non-motor subscale of the QWOQ-9 is 0 to 16. A higher score indicates greater disability. A negative change score indicates improvement.

SECONDARY outcome

Timeframe: Baseline to 15 minutes prior to 2nd dose at Week 8

Population: All subjects that were assessed for efficacy

The QWOQ-9 is a self-rated questionnaire used to assess motor and non-motor symptoms of Parkinson's disease. The 5 motor symptoms are each measured on a five item (0-4) Likert scale, reflecting the severity of the item from "not present" to "very severe". The range of possible score values of the motor subscale of the QWOQ-9 is 0 to 20. A higher score indicates greater disability. A negative change score indicates improvement.
