Current Primary Outcome Measures  ICMJE
 (submitted: February 8, 2021)
  • Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Subscale Score at Week 16: Baseline Observation Carried Forward (BOCF) [ Time Frame: Baseline (Day 1), Week 16 ]
    WOMAC: Self-administered, disease-specific questionnaire which assesses clinically important, participant-relevant symptoms for pain, stiffness and physical function in participants with osteoarthritis. WOMAC pain subscale is a 5-item questionnaire used to assess the amount of pain experienced due to osteoarthritis in hip joint during past 48 hours. It was calculated as mean of the scores from 5 individual questions scored on a numerical rating scale (NRS) of 0 (no pain) to 10 (worst possible pain), where higher scores indicated higher pain. Total score range for WOMAC pain subscale score is 0 (no pain) to 10 (worst possible pain), where higher scores indicated higher pain.
  • Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Physical Function Subscale Score at Week 16: Baseline Observation Carried Forward (BOCF) [ Time Frame: Baseline, Week 16 ]
    WOMAC: Self-administered, disease-specific questionnaire which assesses clinically important, participant-relevant symptoms for pain, stiffness and physical function in participants with osteoarthritis. WOMAC physical function subscale is a 17-item questionnaire used to assess the degree of difficulty experienced due to osteoarthritis in hip joint during past 48 hours. It is calculated as mean of the scores from 17 individual questions scored on a NRS of 0 to 10, where higher scores indicate worse function. Total score range for WOMAC physical function subscale score is 0 to 10, where higher scores indicate worse function. Physical function refers to participant's ability to move around and perform usual activities of daily living.
  • Change From Baseline in Patient Global Assessment (PGA) of Osteoarthritis at Week 16: Baseline Observation Carried Forward (BOCF) [ Time Frame: Baseline, Week 16 ]
    Participants answered: "Considering all the ways your osteoarthritis in your hip joint affects you, how are you doing today?", participants responded by using a 5-point scale where 1 = very good (no symptom and limitation of normal activities) and 5 = very poor (very severe symptoms and inability to carry out normal activities), where lower scores indicates better condition.

Neurologic examination assessed strength of groups of muscles of the head and neck, upper limbs and lower limbs, deep tendon reflexes and sensation (tactile, vibration, joint position sense and pin prick) of index fingers and great toes in order to complete the NIS. The NIS is the sum of scores of over all 37 items (24 scored 0-4; 13 scored 0-2), made separately for left and right sides, giving a possible overall score range of 0 (no impairment) to 122 (severe impairment). NIS Total score range (total of both left and right sides) was 0 (no impairment) to 244 (severe impairment), where higher scores indicated increased impairment.
