E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate the efficacy of at least one dose (among 3 doses) of S201086 compared to placebo after 52 weeks of treatment in reducing cartilage loss measured by cartilage thickness using quantitative magnetic resonance imaging (qMRI) of the central medial tibiofemoral compartment (cMTFC) of the target knee. |
|
E.2.2 | Secondary objectives of the trial |
To assess the safety and tolerability of 3 doses of S201086
To assess efficacy of 3 doses of S201086 versus placebo after 52 weeks of treatment on:
- the proportion of structural progressors based on cartilage thickness using qMRI of the cMTFC of the target knee
- pain, function, and stiffness measured with WOMAC
- pain measured with a 100-mm VAS
- patient global assessment (PGA) of disease activity measured with 100-mm VAS
- reduction of cartilage loss measured by cartilage thickness using qMRI of the total tibiofemoral compartment (tTFC) of the target knee
- Joint Space Width (JSW) measured by x-ray
To assess efficacy of 3 doses of S201086 versus placebo after 28 and 52 weeks of treatment on bone area using qMRI of the medial femoral condyle surface of the target knee
To assess the pharmacokinetics of S201086
To assess efficacy of 3 doses of S201086 versus placebo after 52 weeks of treatment on analgesic consumption |
