The Percentage of Participants Achieving ≥30% Decrease From Baseline in Pain Intensity as Measured by WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) Question 1 "Pain Walking on a Flat Surface" at Week 4
WOMAC for pain assessment by patient (0-100 mm Visual Analog Scale (VAS) with 0 represent "no pain" and 100 represent "extreme pain")
Time frame: Baseline and end of week 4
Mean Change From Baseline in Patient WOMAC Domain Scores at Week 4
The change from baseline in 3 domain scores (pain, stiffness, and difficult in doing daily activity) of WOMAC at week 4 were measured. Each domain comprises of questions and VAS scales for scoring. For pain domain, 0 represents no pain and 100 represents extreme pain; for stiffness domain, 0 represents no stiffness and 100 represents extreme stiffness; for difficult in doing daily activity domain, 0 represents no difficulty and 100 represents most difficulty.
Time frame: Baseline and Week 4
Physicians' Global Assessment of Patients' Response to Therapy at Baseline Using IGART (Investigator Global Assessment of Response to Therapy)
The IGART comprised of five categories: No response, poor response, fair response, good response, and excellent response. The percentage of participants who met the criteria of any of the 5 categories at baseline were collected.
Time frame: Baseline
Physicians' Global Assessment of Patients' Response to Therapy at Week 4 Using IGART
The IGART comprised of five categories: No response, poor response, fair response, good response, and excellent response. The percentage of participants met the criteria of any of the 5 categories at week 4 were collected.
Time frame: Week 4
Patient Assessment of General Health Outcome by EuroQoL-5 Dimensions (EQ-5D) at Baseline
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
The percentage of participants who met the criteria of any of the 3 categories of EQ-5D at baseline and at week 4 were collected.The EQ-5D comprises of 5 dimensions (mobility, self-care, usual activities, pain / discomfort, and anxiety / depression) to be answered using a 3-categorical Likert's scales of: \[No problem, Some problem, and Not able to carry out\] for mobility, self-care and usual activities and \[Not present, moderate and extreme\] for discomfort and anxiety/depression.

Time frame: Week 4
Change From Baseline of Patient BPI (Brief Pain Inventory) Scores at Week 4
BPI consists of pain and pain interference domains. For pain (0=no pain to 10=extreme pain); for pain interference ( 0=no interference to 10= greatest interference).
Time frame: Baseline and Week 4
Changes From Baseline in Patient TSQM (Treatment Satisfaction Questionnaire for Medication) Domain Scores at Week 4
TSQM consists of four domains (effectiveness; side effect; convenience and overall satisfaction), domain scores ranged from 0 (0=worst) to 100 (100=best) were derived from converting the original Likert's scales to VAS scale.
Time frame: Baseline and Week 4
Change From Baseline in Number of Days Patient Miss From Work or House Keeping Work at Week 4
Time frame: Baseline and Week 4
Change From Baseline in Patient-SF36 (Short Form 36) Domain Scores at Week 4
Weighted scores of the 8 domains of SF36 (i.e., physical functioning; role limiting due to physical problem; bodily pain; general health; vitality; social functioning; role limiting due to emotional problem; mental health) were scored on a scale from 0 \~100, with 100 representing the best possible functioning)
Time frame: Baseline and Week 4
