Intervention type: BIOLOGICAL
Group type: EXPERIMENTAL
Intervention: Anti-Thymocyte Globulin - Rabbit
Description: Liver transplantation/Treg-supportive immunosuppression (IS) treatment. Subjects will be given a dose range of 3.0-4.5 mg/kg total, in divided doses of 1.5 mg/kg/day. Subjects who meet eligibility criteria for Thymoglobulin® administration will be given 1.5 mg/kg intravenously (IV) on post-operative day 3, within 72 hours of transplantation. Additional doses of 1.5 mg/kg IV will be administered until CD3 count is \<50/mm\^3 or when the maximal dose of 4.5/mg/kg has been given.
