Active Comparator: Clazakizumab
350 subjects will have a 50/50 chance of being randomly assigned to receive a 12.5 mg subcutaneous (SC) injection once every 4 weeks (Q4W). 175 subjects will be treated with clazakizumab for up to 260 weeks.
Clazakizumab is a genetically engineered humanized immunoglobulin G1 (IgG1) mAb that binds to human IL-6
Placebo Comparator: Placebo
350 subjects will have a 50/50 chance of being randomly assigned to receive a SC injection of normal saline once every 4 weeks (Q4W). 175 subjects will be treated with normal saline for up to 260 weeks.
Drug: Normal saline
- Incidence of all cause composite allograft loss [ Time Frame: Five years ]The aim of this study is to follow enrolled participants until 221 occurrences of all-cause allograft loss, defined as return to dialysis, allograft nephrectomy, re-transplantation, eGFR <15 mL/min/1.73 m2 or death from any cause have been observed. The analysis will be a stratified log rank test of the effect of treatment on all-cause composite allograft loss, with stratification factors of dichotomized baseline eGFR (25-45 mL/min/1.73 m2 versus >45-65 mL/min/1.73 m2), baseline proteinuria, treatment for early (within 6 months of transplant) ABMR rejection episodes (yes/no), and treatment for late (greater than 6 months post transplant) ABMR rejection episodes (yes/no). Surviving subjects without allograft loss will be censored at the time of their last assessment.
