The receptor repertoire diversity was calculated from spectratyping data by creating a normal standard for repertoire diversity from healthy normal controls and assessing the divergence of individual patient's T cell receptor repertoire from these standard normal donor values. In this Vbeta repertoire divergence index, lower numbers are consistent with a more normal highly diverse repertoire, and high numbers represent a highly skewed, oligoclonal repertoire. The assay is described in Memon SA et al, J Immunol Methods, 2012, 375: 84-92. The repertoire diversity of the CD4 and CD8 T cells of the donor infusion is shown for comparison.","dispersionType":"Full Range","groups":[{"description":"Rituximab: 375 mg/m2 intravenous (IV), day 1 for patients (pts) with cluster of differentiation 20-positive disease.
