This is a Phase 2, multi-center, randomized, double-blind, placebo-controlled, parallel design study evaluating, in a pilot stage of the study, up to 3 ascending dose level cohorts each evaluating a single dose of CA-008 vs. placebo injected/instilled during an elective TKA. Up to 54 subjects will be randomized in the pilot stage. During the optional second stage of the study, subjects will be randomized to one of either 2 or 3 CA-008 dose levels (to be determined) or placebo. The Sponsor made the decision not to proceed with the second stage.
