About
The purpose of this study was to investigate how efficiently the study medication imlifidase reduces the amount of donor specific antibodies (DSA) in comparison with plasma exchange (PE) therapy, in patients who have had an active or chronic active antibody mediated rejection (AMR) after being kidney transplanted. The purpose was also to investigate and compare safety for these two treatments.
Full description
Antibodies to HLA antigens have a strong correlation with allograft injury and loss. Treatment with imlifidase, PE and immunoabsorption (IA) all aim to reduce antibody levels.
This study will compare the reduction in DSA levels after treatment with imlifidase and PE in patients diagnosed with active or chronic active AMR (according to Banff 2017 criteria) having at least a 25% rise in serum creatinine compared with last measurement prior to the AMR (Patients with delayed graft function and AMR within 10 days after kidney transplantation can be included regardless of serum creatinine level).
Included patients will be randomized to receive either 1 dose of imlifidase (0.25 mg/kg) or 5-10 sessions of PEs (IA may replace PE at the discretion of the investigator). All patients will receive pulse methylprednisolone for 3 days, starting before the 1st treatment, followed by a tapering schedule with prednisolone/prednisone. The patients will also receive high dose IVIg 3 days after imlifidase treatment or directly after the last PE. In addition a single dose of rituximab will be given 5 days after completed IVIg infusion.
