REgulatory T Cell Therapy to Achieve Immunosuppression REduction

Description

This is a prospective, multi-national, multi-center, open-label, randomized Phase 2 trial to determine the safety and efficacy of administering autologous expanded regulatory T cells (TRK-001) to prevent allograft rejection in living donor renal transplant recipients.

All subjects will be followed for 5 years post-transplant, comprising of a 2-year post-transplant follow-up period and a 3-year surveillance period.

Subjects with end-stage renal disease undergoing a living donor kidney transplant will be enrolled into the trial as follows:

Arm 1 SOC: Standard of care immunosuppression (N=14)

Arm 2 TRACT/MONO: TRK-001 and initial SOC immunosuppression weaned to monotherapy (N=20)

At Month 3 post-transplant, Arm 2 subjects will be further randomized prior to weaning to either mTOR or CNI monotherapy as follows:

Arm 2A: TRACT/MONO mTOR (N=10) or Arm 2B: TRACT/MONO CNI (N=10)
