This study will evaluate dosing regimens of 4975 in terms of safety and tolerability when delivered as an intra-articular injection in the knee. Secondary objectives will be to explore the efficacy of 4975 in terms of onset, extent and duration of pain relief.
This is a single site study. The study drug, 4975, will be administered in various dosing regimens by intra-articular injection followed by an observation period of up to 12 weeks. Pain in the treated knee will be assessed before, during and after administration of the study drug.
