Overview
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.

Outcomes
Primary Outcomes
Rate of Progression of Joint Space Narrowing
Time Frame: Baseline up to Month 24
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 Joint Space Narrowing in Participants With Kellgren and Lawrence Grade Less Than or Equal to (<=) 2
Time Frame: Baseline up to Month 24
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.
Rate of Progression of Joint Space Narrowing in Participants With Kellgren and Lawrence Grade Equal to (=) 3
Time Frame: Baseline up to Month 24
