Primary Outcome Measures

Name	Time	Method
Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Physical Function Subscale Score at Week 16: Baseline Observation Carried Forward (BOCF)	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)	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.
Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Subscale Score at Week 16: Baseline Observation Carried Forward (BOCF)	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.

An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to Week 32 that were absent before treatment or that worsened relative to pretreatment state. Adverse events included both serious and all non-serious adverse events.
Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC) Pain Subscale Item (Pain When Walking on Flat Surface) Score at Week 2, 4, 8, 12, 16 and 24 : Baseline Observation Carried Forward (BOCF)	Baseline, Week 2, 4, 8, 12, 16, 24	WOMAC: Self-administered, disease-specific questionnaire which assesses clinically important, participant-relevant symptoms for pain, stiffness and physical function in participants with osteoarthritis.
