Our initial plan for induction for a patient with a negative crossmatch was rATG alone.
This is the first reported facial VCA utilizing an induction regimen of rATG in combination with rituximab.

Patients that did not respond to hATG after 3 months of treatment, received ATG of rabbit origin (rATG) at a dose of 3.75 mg/kg/day for 5 days and CsA was continued at the same dosage.

In total, 9 patients did not respond to 3 months of treatment; 7 subsequently received a second course of 1ST consisting of rATG. Prednisolone treatment was repeated and the patients received CsA treatment as the same dosage for six months.

Clinically, two randomized studies in kidney transplantation have addressed the question of whether rATG can influence the impact of IRI on graft function.
in a rat model of transplantation, where administration of anti-rat rATG to the donor prior to organ retrieval ameliorated IRI, as shown by lower necrosis and apoptosis scores and better early graft function [44].
The profound suppression of T-cells induced by rATG confers a potent immunosuppressive effect, and its efficacy in preventing acute rejection after kidney transplantation is well-accepted [48].
published a randomized trial in which 308 patients at varying levels of immunological risk received either rATG (at a total dose of 12.5 mg/kg, starting after surgery) with tacrolimus delayed until day 9 or no induction with tacrolimus started on the day of transplantation [57].
