A PIVOTAL PHASE 3 TRIAL TO EVALUATE THE SAFETY AND EFFICACY OF CLAZAKIZUMAB FOR THE TREATMENT OF CHRONIC ACTIVE ANTIBODY-MEDIATED REJECTION IN KIDNEY TRANSPLANT RECIPIENTS

Primary Objective

Primary Objectives: 1. To evaluate the efficacy of clazakizumab in preventing all-cause composite allograft loss due to CABMR (defined as return to dialysis, allograft nephrectomy, re-transplantation, eGFR <15 mL/min/1.73 m2 or death from any cause (including death with functioning allograft). 2. To evaluate the efficacy of clazakizumab in slowing/preventing the progressive loss of kidney function (as measured by eGFR using the MDRD4 equation). 3. To evaluate the safety of clazakizumab. Secondary Objectives: 1. To evaluate the effects of clazakizumab on death-censored allograft loss (defined as return to dialysis, allograft nephrectomy, re-transplantation or eGFR <15 mL/min/1.73 m2 but excluding death from any cause). 2. To evaluate the effects of clazakizumab on albuminuria. 3. To evaluate the effects of clazakizumab on DSA titers and mean fluorescence intensity (MFI) scores. 4. To evaluate the effects of clazakizumab on incidence of acute rejection episodes (TCMR and ABMR). 5. To evaluate the effects of clazakizumab on the histology of kidney biopsies according to the Banff 2015 lesion grading scores. 6. To evaluate the effects of clazakizumab on overall patient survival. 7. To evaluate the effects of clazakizumab on healthcare utilization due to ABMR and patient reported outcomes, including health-related quality of life (HRQoL).

Description

This multi-center, randomized, double-blind, parallel-group, placebo-controlled, Phase 3 trial investigates whether clazakizumab (an anti-IL-6 mAb) may be beneficial for the treatment of CABMR in kidney transplant recipients by inhibiting the production of DSA and re-shaping T cell alloimmune responses. Subjects will be administered clazakizumab at a target dose of 12.5 mg (or placebo) by SC injection, Q4W for up to 260 weeks (or until allograft loss or death).
