A Study to Evaluate TOUR006 in Patients With Chronic Kidney Disease and Elevated Hs-CRP

Previous clinical studies have suggested that IL-6-driven inflammation plays a key role in the pathogenesis of cardiovascular diseases including atherosclerotic cardiovascular disease (ASCVD) and heart failure. This Phase 2 study will evaluate the safety, tolerability, pharmacokinetics, and CRP-lowering effect of quarterly and monthly subcutaneous administration of TOUR006, a fully human monoclonal antibody against IL-6. TOUR006 binds the IL-6 cytokine and inhibits downstream IL-6 signaling, thereby reducing the pharmacodynamic marker, hs-CRP.
