Study Summary

This phase 2 study is a placebo-controlled, double-blind, parallel group study of four concentrations of SM04690 (0.03, 0.07, 0.15, and 0.23 mg per 2 mL injection) injected intraarticularly (IA) into the target knee joint of subjects with moderately to severely symptomatic osteoarthritis (OA). Based on previous studies of SM04690, key phenotypes of laterality (unilateral vs bilateral) as well as chronic pain (as measured by the Widespread Pain Index) were identified as confounding variables impacting the overall assessment of both radiologic and clinical efficacy outcomes. The design of SM04690-OA-04 is based upon previous study designs while assessing strategies to combat the confounding impact of laterality and chronic pain. To evaluate the effect of IA vehicle injection on patient-reported outcomes (PRO) such as pain, stiffness, and function in OA, this study also includes one cohort that receives a 2 mL IA injection of vehicle (placebo), and one cohort that receives a sham injection (i.e., a needle stick with 0 mL vehicle injected).

Primary Outcome

Change from baseline OA pain in the target knee as assessed by the weekly average of daily pain NRS at Week 24. The pain NRS is an 11-point scale \[0-10\] for subject self-reporting of average knee pain in the last 24 hours; 0 indicates no pain, and 10 represents the worst possible pain (pain as bad as one can imagine).
