Outcome Measures

Primary Outcomes (3)

  • Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Subscale at Week 16: Baseline Observation Carried Forward (BOCF)

    WOMAC: Self-administered, disease-specific questionnaire which assesses clinically important, participant-relevant symptoms for pain, stiffness and physical function in participants with osteoarthritis (OA). WOMAC pain subscale is a 5-item questionnaire used to assess the amount of pain experienced due to osteoarthritis in index knee during past 48 hours. It is calculated as mean of the scores from 5 individual questions, each scored on a numerical rating scale (NRS) of 0 (no pain) to 10 (extreme pain), where higher scores indicate higher pain. Total score range for WOMAC pain subscale score is 0 (no pain) to 10 (extreme pain), where higher scores indicate higher pain.

    Baseline (Day 1), Week 16

  • Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Physical Function Subscale at Week 16: Baseline Observation Carried Forward (BOCF)

    WOMAC: Self-administered, disease-specific questionnaire which assesses clinically important, participant-relevant symptoms for pain, stiffness and physical function in participants with OA. WOMAC physical function is a 17-item questionnaire used to assess the degree of difficulty experienced due to osteoarthritis in index knee during past 48 hours. It is calculated as mean of the scores from 17 individual questions, each scored on a NRS of 0 (no difficulty) to 10 (extreme difficulty), where higher scores indicate worse function. Total score range for WOMAC physical function subscale score is 0 (no difficulty) to 10 (extreme difficulty), where higher scores indicate worse function. Physical function refers to participant's ability to move around and perform usual activities of daily living.

    Baseline, Week 16

  • Change From Baseline in Patient Global Assessment (PGA) of Osteoarthritis at Week 16: Baseline Observation Carried Forward (BOCF)

    Participants answered: "Considering all the ways your osteoarthritis in your knee affects you, how are you doing today?". Participants responded on a scale ranging from 1-5, where 1= very good (no symptom and no limitation of normal activities), 2= good (mild symptoms and no limitation of normal activities), 3= fair (moderate symptoms and limitation of some normal activities), 4= poor (severe symptoms and inability to carry out most normal activities), and 5= very poor (very severe symptoms and inability to carry out all normal activities). Higher scores indicated worsening of condition.
