Trial Outcomes & Findings for Study to Evaluate the Efficacy, Safety, Tolerability and Pharmacokinetics of AZD1386 in Patients With Osteoarthritis (OA) of the Knee (NCT NCT00878501)

NCT ID: NCT00878501

Last Updated: 2012-06-04

Results Overview

The WOMAC pain subscale is a self-administered electronic scale with 5 questions (Walking on flat surface, Going up or down stairs, At night while in bed, Sitting or lying, Standing upright). Responses were recorded on a 50-mm line with 100 units. 0 mm indicated no pain and 50 mm indicated extreme pain. The scores were then converted to a 100-mm scale. WOMAC pain was derived by calculating the mean of the VAS scores from the 5 questions with score scale ranging from 0 to 100, 0 being no pain and 100 extreme pain.

Participant Flow

International multi-center study, 41sites in North America, Japan and Europe recruited between March and July 2009. 327 participants enrolled into the study

Patients with past or ongoing intolerability to NSAID´s/COX-2's or paracetamol/acetaminophen or patients with insufficient pain relief from these treatments were included in the study. The WOMAC pain on walking had to be ≥40 mm and ≤90 mm on a Visual Analogue Scale (VAS) at both enrolment and after 1 weeks wash-out of medication (randomisation)

Timeframe: Baseline, Week 2 and Week 4.

Population: Number of Participants Analyzed for the stated measure are defined according to the Modified Intention To Treat analysis set whereas numbers provided in the Participant Flow Module correspond to number of participants enrolled.

The WOMAC VA 3.1. is a self-administered electronic questionnaire that assesses pain, stiffness and disability related to OA. The Function (daily activities) subscale consists of 17 questions. WOMAC function was derived by calculating the mean of the VAS scores from the 17 questions with scores ranging from 0 to 100, 0 = no difficulty in performing daily activities and 100 = extreme difficulty.

Population: Number of Participants Analyzed for the stated measure are defined according to the Modified Intention To Treat analysis set whereas numbers provided in the Participant Flow Module correspond to number of participants enrolled.

The WOMAC VA3.1. is a self-administered questionnaire that assesses pain, stiffness and disability related to osteoarthritis. The Stiffness subscale consists of 2 questions (Severity of stiffness after first awakening in the morning and severity of stiffnes after periods of inactivity later in the day). WOMAC stiffness was derived by calculating the mean of the VAS scores from the 2 questions with score scale ranging from 0 to 100, 0 being no stiffness and 100 extreme stiffness.

The WOMAC VA3.1. is a self-administered questionnaire that assesses pain, stiffness and disability related to osteoarthritis. It consists of a pain subscale (5 questions), function subscale (17 questions). and a stiffness subscale (2 questions). The total score was derived by calculating the mean of the VAS scores from all 24 questions with score scale ranging from 0 to 100, 0 being no pain, stiffness and difficulty in performing daily activities and 100 being extreme pain, stiffness and difficulty in performing daily activities.
