Primary Outcome Measures
NameTimeMethod
Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Subscale Score at Week 8: ITT PopulationBaseline, Week 8

The WOMAC pain subscale is a 5-item questionnaire used to assess the amount of pain experienced due to osteoarthritis (OA) in the index joint (knee/hip) during past 48 hours. It is calculated as the mean of the scores from the 5 individual questions scored on a numerical rating scale (NRS) of 0 to 10, where higher scores indicate higher pain. Total score range for WOMAC pain subscale score is 0 to 10, where higher scores indicate higher pain.

Pre-specified opioid-related adverse events: fatigue, drowsiness, inability to concentrate, nausea, dizziness, constipation, itching, difficulty urinating, confusion and vomiting. Number of participants who experienced any of the pre-specified opioid-related adverse event are reported. Pre-specified opioid-related adverse events were assessed according to severity: mild (did not interfere with participant's usual function); moderate (interfered to some extent with participant's usual function); and severe (interfered significantly with participant's usual function).
