A 12 month, partially-blinded, active-controlled, multicenter, randomized study evaluating efficacy, safety, tolerability, pharmacokinetic (PK) and pharmacodynamic (PD) of an anti-CD40 monoclonal antibody, CFZ533, in de novo and maintenance kidney transplant recipients (CIRRUS I)

Primary Objective

COHORT 1: Primary Objective(s) -To demonstrate that CFZ533 600 mg or 300 mg bi-weekly (Q2W), subcutaneous (SC), are non-inferior to a tacrolimus-based regimen with respect to the proportion of patients who experience the composite efficacy failure event (Biopsy proven acute rejection (BPAR), Graft Loss or Death) over 12 months post-transplantation. Key secondary objective: -To demonstrate that CFZ533 600 mg or 300 mg Q2W SC are superior to a tacrolimus-based regimen with respect to the mean estimated glomerular filtration rate (eGFR) at 12 months post-transplantation. COHORT 2: Primary Objective(s) -To demonstrate that CFZ533 450 mg Q2W SC is non-inferior to a tacrolimus-based regimen with respect to the proportion of patients who experience the composite event (BPAR, Graft Loss or Death) over 12 months post conversion. Key secondary objective: -To demonstrate that CFZ533 450 mg Q2W SC is superior to a tacrolimus-based regimen with respect to the mean change in eGFR from baseline to 12 months post conversion.

Description

Study CCFZ533A2201 is a randomized, 12-month, active-controlled, partially-blinded, multicenter, dose range finding study to evaluate the efficacy, safety, tolerability, PK and PD of CFZ533 in 2 different cohorts: -In adult de novo kidney transplant recipients, CFZ533 in combination with MMF and corticosteroids as compared to standard of care comprised of tacrolimus, MMF and corticosteroids. -In a maintenance kidney transplant population (6-24 months post-transplant), CFZ533 in combination with MMF with or without corticosteroids, compared to a standard of care control arm of tacrolimus and MMF with or without corticosteroids.

Phase

II - Research Studies that gather preliminary data on whether a drug works in people who have a certain condition/disease (that is, the drug's effectiveness). For example, participants receiving the drug may be compared to similar participants receiving a different treatment, usually an inactive substance (called a placebo) or a different drug. Safety continues to be evaluated, and short-term adverse events are studied.
