Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Knee Pain Over the Course of the 26-week Initial Treatment Period As Measured by Participants Using the Western Ontario and McMaster Universities Osteoarthritis Index Likert Scale Version 3.1 (WOMAC LK 3.1) A (Pain) Subscale
Time Frame: Day 0, up to week 26
The change from baseline over the course of the 26-week initial treatment period using participants' assessment of pain. Mean scores were used for baseline (day 0) and for all visits up to week 26 (weeks 4, 8, 12, 18 and 26). The WOMAC Pain Subscale has a score range of 0-4, where 0=no pain and 4=extreme pain.
Day 0, up to week 26

Secondary Outcome Measures

Measure Description
Time Frame

Mean scores were used for baseline (day 0) and for all visits up to week 26 (weeks 4, 8, 12, 18 and 26). The WOMAC Function Subscale has a score range of 0-4 to assess the degree of difficulty completing tasks within the past 48 hours, where 0=no difficulty and 4=extreme difficulty.

Time Frame: Week 26
The Participant Global Assessment (PTGA) was used by participants to rate their osteoarthritis (OA). PTGA uses 5 scoring levels: Very well=0, Well=1, Fair=2, Poor=3, Very poor=4.
Week 26
Clinical Observer Global Assessment (COGA) of the Target Knee Osteoarthritis (OA) Condition at Week 26
Time Frame: Week 26
The Blinded Clinical Observer gave a global assessment (COGA) of the target knee OA. COGA uses 5 scoring levels: Very well=0, Well=1, Fair=2, Poor=3, Very poor=4.
Week 26
Participants Classified as Responders Per the Outcome Measures in Rheumatology-Osteoarthritis Research Society International (OMERACT-OARSI) Criteria at Week 26
Time Frame: Week 26

Participants were classified as a positive responder if at least one of the following two conditions were met:

  1. A significant improvement in either the pain (WOMAC A) or physical function (WOMAC C) subscales, defined as both a ≥ 50% improvement from Baseline and an absolute change from Baseline of ≥ 20 normalised units (NU), OR
  2. Improvement in at least 2 of 3 subscales - pain (WOMAC A), physical function (WOMAC C) or Participant Global Assessment (PTGA). Improvement for all three scales is defined as ≥ 20% improvement from Baseline and an absolute change from Baseline of ≥ 10 NU
