The purpose of this study is to investigate the safety, efficacy, pharmacokinetics (PK) and pharmacodynamics (PD) of three CFZ533 dose regimens in kidney transplant recipients.
This study will allow assessment of the ability of CFZ533 to replace Calcineurin inhibitors (CNIs) in terms of anti-rejection efficacy, while providing better renal function with a better safety and tolerability profile. Results of this study will be used to inform the CFZ533 dose and regimen selection for investigation in later phases of clinical development.
