MeasureTime frameDescription
Percentage of Participants With >=2 Points Improvement in PGAO From Baseline at Weeks 2, 4, 8, and 12Baseline, Weeks 2, 4, 8 and 12PGAO questionnaire (Considering all the ways your osteoarthritis in your knee affects you, how are you doing today?) was comprised of 5 grades with 1=very good to 5=very poor, where higher grades indicated more effect of osteoarthritis. The treatment response of an improvement of \>=2 points from Baseline in PGAO were summarized.
Change From Baseline in Short-Form 36 Health Survey (SF-36) Domain Scores and Component Scores at Week 12Baseline and Week 12The SF-36 is a self-administered questionnaire that measures each of the following 8 health domains: physical functioning, role limitations due to physical problems (role-physical), social functioning, bodily pain, mental health, role limitations due to emotional problems (role-emotional), vitality, and general health perception. There are also 2 component scores derived from the 8 subscale scores: physical component summary (including physical functioning, role-physical, bodily pain and general health) and mental component summary (including vitality, social functioning, role-emotional and mental health). Each SF-36 domain and component summary score ranges from 0 to 100, higher scores reflect better participant health status.
Change From Baseline in WOMAC Subscale and Average Scores at Weeks 2, 4, 8 and 12Baseline, Weeks 2, 4, 8 and 12The WOMAC has 3 subscales: WOMAC pain subscale, WOMAC stiffness subscale and WOMAC physical function subscale, which are comprised of 5, 2 and 17 questions regarding the amount of pain and stiffness experienced in the index knee, and degree of difficulty in doing daily tasks, respectively in the past 48 hours. The WOMAC subscale scores range from 0 to 10 with higher scores indicating higher pain, more stiffness and worse function respectively for pain, stiffness and physical function subscales. The WOMAC subscale scores were calculated as the mean of the scores from the individual questions. Change from baseline was calculated for each WOMAC subscale (pain, stiffness, physical function) and WOMAC average score.
Change From Baseline in Weekly Average Pain Score in the Index Knee Using 11-point Numeric Rating Scale (NRS) at Weeks 2, 4, 8 and 12Baseline, Weeks 2, 4, 8 and 12Daily average knee pain was assessed with an 11-point NRS ranging from 0 (no pain) to 10 (worst possible pain), where higher scores indicated worse pain. The participants described their pain in the index knee during the past 24 hours by choosing the appropriate number from 0 to 10.
Percentage of Participants With Change From Baseline in EuroQoL-5 Domains (EQ-5D) Level at Week 12Baseline and Week 12The EQ-5D is a generic measure of health related quality of life. The EQ-5D has 5 items that assess the level of difficulty (none \[score of 1\], some/moderate \[score of 2\], extreme \[score of 3\]) respondents report for 5 health status domains: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The change from Baseline (decrease by 2, 1, 0, -1 and -2) at Week 12 in each of the 5 health status domains were summarized.

The WOMAC pain subscale scores range from 0 to 10 with higher scores indicating higher pain. The WOMAC pain subscale score was calculated as the mean of the scores from the individual questions. WOMAC pain subscale response rates at Week 12 were shown for the reductions from Baseline of greater than (\>) 0%, 10% to 90% (in steps of 10%).
Percentage of Participants With at Least 30% and 50% Reduction From Baseline in the WOMAC Pain Subscale at Weeks 2, 4, 8, and 12Baseline, Weeks 2, 4, 8 and 12WOMAC pain subscale is comprised of 5 questions regarding the amount of pain experienced in the index knee in the past 48 hours. The WOMAC pain subscale scores range from 0 to 10 with higher scores indicating higher pain. The WOMAC pain subscale score was calculated as the mean of the scores from the individual questions.

Change From Baseline in Short-Form 36 Health Survey (SF-36) Domain Scores and Component Scores at Week 12

The SF-36 is a self-administered questionnaire that measures each of the following 8 health domains: physical functioning, role limitations due to physical problems (role-physical), social functioning, bodily pain, mental health, role limitations due to emotional problems (role-emotional), vitality, and general health perception. There are also 2 component scores derived from the 8 subscale scores: physical component summary (including physical functioning, role-physical, bodily pain and general health) and mental component summary (including vitality, social functioning, role-emotional and mental health). Each SF-36 domain and component summary score ranges from 0 to 100, higher scores reflect better participant health status.

Time frame: Baseline and Week 12

Population: FAS: all randomized participants who received at least 1 dose of study medication using BOCF imputation method, number of participants analyzed=number of participants evaluable for the outcome measure, n=number of evaluable participants for each specific SF-36 domain.

Change From Baseline in Weekly Average Pain Score in the Index Knee Using 11-point Numeric Rating Scale (NRS) at Weeks 2, 4, 8 and 12

Daily average knee pain was assessed with an 11-point NRS ranging from 0 (no pain) to 10 (worst possible pain), where higher scores indicated worse pain. The participants described their pain in the index knee during the past 24 hours by choosing the appropriate number from 0 to 10.

Change From Baseline in WOMAC Subscale and Average Scores at Weeks 2, 4, 8 and 12

The WOMAC has 3 subscales: WOMAC pain subscale, WOMAC stiffness subscale and WOMAC physical function subscale, which are comprised of 5, 2 and 17 questions regarding the amount of pain and stiffness experienced in the index knee, and degree of difficulty in doing daily tasks, respectively in the past 48 hours. The WOMAC subscale scores range from 0 to 10 with higher scores indicating higher pain, more stiffness and worse function respectively for pain, stiffness and physical function subscales. The WOMAC subscale scores were calculated as the mean of the scores from the individual questions. Change from baseline was calculated for each WOMAC subscale (pain, stiffness, physical function) and WOMAC average score.

Time frame: Baseline, Weeks 2, 4, 8 and 12

Percentage of Participants With Change From Baseline in EuroQoL-5 Domains (EQ-5D) Level at Week 12

The EQ-5D is a generic measure of health related quality of life. The EQ-5D has 5 items that assess the level of difficulty (none \[score of 1\], some/moderate \[score of 2\], extreme \[score of 3\]) respondents report for 5 health status domains: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The change from Baseline (decrease by 2, 1, 0, -1 and -2) at Week 12 in each of the 5 health status domains were summarized.

Time frame: Baseline and Week 12

Population: FAS: all randomized participants who received at least 1 dose of study medication using BOCF imputation method, number of participants analyzed=number of participants evaluable for the outcome measure, including the 12 participants (5 placebo, 7 meloxicam) who had missing baseline EQ-5D data.

Percentage of Participants With Cumulative Reduction From Baseline in WOMAC Pain Subscale at Week 12

WOMAC pain subscale is comprised of 5 questions regarding the amount of pain experienced in the index knee in the past 48 hours. The WOMAC pain subscale scores range from 0 to 10 with higher scores indicating higher pain. The WOMAC pain subscale score was calculated as the mean of the scores from the individual questions. WOMAC pain subscale response rates at Week 12 were shown for the reductions from Baseline of greater than (\>) 0%, 10% to 90% (in steps of 10%).

Time frame: Baseline and Week 12

Population: FAS: all randomized participants who received at least 1 dose of study medication using BOCF imputation method, number of participants analyzed=number of participants evaluable for the outcome measure.
