Summary

This study seeks to determine if administration of the drug belumosudil (KD025) will be safe and improve transplant tolerance in subjects undergoing combined Human Leukocyte Antigen (HLA) single haplotype-matched related or 0-3 antigen (at A, B, C, DR) HLA mismatched unrelated living donor kidney and hematopoietic stem cell transplantation.

COMBINATION_PRODUCT

Donor CD34+, CD3+. and belumosudil

Immediately after living donor kidney transplantation, subjects will begin a conditioning regimen of rATG and total lymphoid irradiation. An infusion of at least 8 X106 donor CD34 cells/kg recipient weight and of at least 10 X106 donor CD3 cells/kg recipient weight will then be given. A triple immunosuppressive regimen of tacrolimus, corticosteroids, and mycophenolate will be utilized. Corticosteroids will be given on a tapering schedule from day 0 through the first four months. Tacrolimus will be given on a tapering schedule from day 1 through month 18. Mycophenolate will be given at a fixed dose from day 11 through month 12. Subjects will receive belumosudil 200 mg by mouth daily from day 28 following the kidney transplant through month 24.
