Rate of Progression of Joint Space Narrowing
Query!
Assessment method [1]
0
0
Rate of progression of joint space narrowing (JSN) was defined as narrowing in joint space width (JSW) over the course of the study. It was measured radiographically in the medial tibiofemoral of knee of participants with OA. The slope reported in millimeter per year (mm/year) over a 2 year period was used to assess the rate of progression of JSN. Negative values indicating a worsening of osteoarthritis.

Rate of progression of JSN was defined as narrowing in joint space width over the course of the study. It was measured radiographically in the medial tibiofemoral of knee of participants with OA. The slope reported in mm/year over a 2 year period was used to assess the rate of progression of JSN. KLG system was a method of classifying the severity of knee OA using five grades (0 \[no severity\] to 4 \[maximum severity\], higher grade indicating worse knee function). Negative values of slope indicating a worsening of osteoarthritis.

The WOMAC was a self-administered, disease-specific instrument which probed clinically important, participant relevant symptoms in the areas of pain, stiffness, and physical function in participants with OA of the knee. The WOMAC composite index was the sum of 24 individual questions regarding subscales of pain, stiffness and physical function (for each item score range: 0 \[minimum\] to 4 \[maximum\], higher score indicating worse knee condition). Total score was sum of the 3 subscale scores, giving a possible overall score range of 0 (minimum) to 96 (maximum). Higher score indicating the worse level of pain, stiffness and physical function.

The SF-36 was a participant administered scale assessing general quality of life. It consisted of self-administered 36-item questionnaire that measured 8 health domains: physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health. These 8 domains were also summarized as physical and mental component scores. The score for each domain and component score was the mean of the individual question scores, which were scaled from 0 (minimum) to 100 (maximum), where higher scores indicated highest level of health/functioning. Linear transformations were performed to transform scores and rescaled to a score range of 16.18 (minimum) to 57.11 (maximum), with higher scores indicating better physical functioning.

Patient global impression of change was a participant-rated instrument that measured change in participant's overall status on a 7-point scale ranging from: 1 =very much improved, 2 =much improved, 3 =minimally improved, 4 =no change, 5 =minimally worse, 6 =much worse and 7 =very much worse. Higher scores indicating worse condition.

The OMERACT-OARSI responder index was used to determine whether participants may be considered responders to treatment. An OMERACT-OARSI responder was a participant who had a better response on the WOMAC pain subscale score, a better response on the WOMAC physical function subscale score or improvement on at least two of the three domains: WOMAC pain subscale score (overall score range of 0 \[minimum\] to 20 \[maximum\], higher scores indicating more pain), WOMAC physical function subscale score (overall score range of 0 \[minimum\] to 68 \[maximum\], higher scores indicating worse physical function) and patient global assessment of arthritic condition score (overall score range of 1 \[minimum\] to 5 \[maximum\], higher scores indicating worse condition). Number of participants who were OMERACT-OARSI responder were reported in this measure.

Summary
Brief summary
The objective of this 2-year study is to evaluate the safety, tolerability and disease modifying efficacy of SD 6010, an inhibitor of inducible nitric oxide synthase (iNOS), in overweight and obese subjects with knee osteoarthritis. The efficacy of SD-6010 will be evaluated by radiography using joint space narrowing in the medial tibiofemoral compartment of the study knee as the primary endpoint.
