2. This minimization protocol will be delayed by 3 months if biopsy proven acute cellular rejection occurs. For example, if rejection occurs, Tacrolimus is increased to month 1 levels of 12-15 ng/ml, and steroids added to the regimen. Steroids will be eliminated within 3 months of rejection, and Tacrolimus minimization resumed as described above. These protocols are our standards of care in the event of rejection, whether we use the rATG induction approach with steroid-free Tacrolimus, or Tacrolimus with steroids.
