Antibody Mediated Rejection clinical trials at UCLA

The primary objective of this study is to evaluate the efficacy of ALXN2030 compared with placebo on biopsy proven histologic resolution in participants with active or chronic active antibody-mediated rejection (AMR) at Week 52.

Primary Objectives: - Cohort A: To evaluate the efficacy of BIVV020 in prevention of AMR - Cohort B: To evaluate the efficacy of BIVV020 in treatment of active AMR Secondary Objectives: - To assess the overall efficacy of BIVV020 in prevention or treatment of AMR - To characterize the safety and tolerability of BIVV020 in kidney transplant participants - To characterize the pharmacokinetic (PK) profile of BIVV020 in kidney transplant participants - To evaluate the immunogenicity of BIVV020

The purpose of this study is to see: 1. If using these two drugs (carfilzomib and belatacept) together is safe 2. If the use of these two study drugs in addition to the usual immunosuppression for kidney transplant patients can improve your transplanted kidney function by lowering the antibodies you have against your transplanted kidney 3. If the study drugs effect the immune cells that were responding to your donor kidney. And, whether blood or urine tests can measure signs of inflammation and kidney cell injury 4. If using new computer techniques can help describe important changes seen on biopsy in your donated kidneys The primary objective is to assess the efficacy of carfilzomib and belatacept therapy when added to current treatment with steroids and maintenance immunosuppression, compared to conventional treatment alone, to improve the clinical outcome of renal transplant patients with active and chronic - active ABMR occurring more than 6 months after renal transplantation or less than 6 months post-transplant with persistent refractory Antibody-Mediated Rejection (ABMR)
