Efgartigimod in Kidney Transplant Recipients With AMR - SHAMROCK

Purpose of this Study

We are doing this study to find out if an experimental drug called efgartigimod (the study drug) is a safe and effective option for people experiencing kidney rejection. We want to know if it can decrease antibody-mediated rejection following a transplant by removing the antibodies that target and damage the cells of the donated kidney.

Who Can Participate?

Eligibility

Adults ages 18-80 who:
  • Received a kidney transplant at least 6 months ago
  • Are diagnosed with biopsy-confirmed antibody-mediated rejection
  • Are using an immunosuppressing medication for maintenance following their transplant

Description

If you choose to join this study, you will get a random assignment (fair, equal chance) to 1 of 3 groups. Depending on your group assignment, you may:
  • Take the study drug for 48 weeks; OR
  • Take a placebo (inactive substance with no drug in it) for 48 weeks; OR
  • Take a combination of the study drug (first 24 weeks) and a placebo (second 24 weeks)
The study will last for about 20 months, and it involves at least 20 study visits. The study visits will include the following procedures: study drug injections, physical exams, blood draws, biopsies, chest x-ray, electrocardiograms, and genetic tests.
