Four patients in each arm had no detectable tumor cells in the first leukapheresis. After CD34 selection, 11 of the 24 patients in the CD34-selected arm had no detectable tumor cells. Thus, a total of 15 patients (54%) received an infused product with no detectable tumor cells in the CD34-selected arm compared with 4 patients (21%) in the unselected arm.
