About this trial

This is an open-label, single-institution study to assess the safety and the efficacy of the Sip-Tego regimen for the induction of donor-specific immunologic unresponsiveness to a renal allograft. The investigators propose to treat 6 adult subjects in end-stage renal disease (ESRD) who do not demonstrate evidence of prior sensitization.

Eligibility criteria

Candidate for a living-donor renal allograft from an HLA matched or mismatched donor

First or second renal transplant.

Disqualifiers

ABO blood group-incompatible renal allograft

Participant with a donor-specific antibody (DSA) within 6 months prior to transplant
