Patient 7 had been refractory to ganciclovir and patient 8 had been refractory to cidofovir.
Purity was reduced due to the low frequency of the CMV-specific CD8+ T cells in the donor (0.08% of CD8+ cells). The depletion of cells not binding tetramer was >3 log. CMV epitopes are as follows: ELR-IE1199-207; IPS-pp65123-131; NLV – pp65495-503; TPR-pp65417-426; YSE-pp65363-373.
ALC, absolute lymphocyte count; ALL, acute lymphoblastic leukemia; AML, acute myeloid leukemia; BC, BEAM/Campath-1H; Bu, busulfan; CLL, chronic lymphocytic leukemia; CML, chronic myeloid leukemia; Cy, cyclophosphamide; FMC, fludarabine melphalan Campath-1H; HD, Hodgkin's disease; TBI, total body irradiation; WM, Waldenström's macroglobulinemia.
