Added text to state that obinutuzumab is a human anti-CD20 monoclonal antibody treatment option and provided statistics from a randomized prospective trial (NCT01010061) of 781 previously untreated patients with coexisting medical problems who were randomly assigned to chlorambucil plus obinutuzumab versus chlorambucil plus rituximab versus chlorambucil alone (cited Goede et al. as reference 16 and level of evidence (LOE) 1iiA).
Added text to state that idelalisib is an oral inhibitor of the delta isoform of the phosphatidylinositol 3-kinase and provided statistics from a randomized, double-blind, prospective trial (NCT01539512) of 220 patients treated mainly with fludarabine-based regimens who had coexisting medical problems and received rituximab plus idelalisib versus rituximab plus placebo (cited Furman et al. as reference 17 and LOE 1iA).
Added O'Brien et al. as reference 19.
Added text to state that a series of 90 patients with relapsed or refractory CLL who underwent allogeneic stem cell transplantation reported a 58% 6-year overall survival rate and a 38% 6-year event-free survival rate, which included those patients with the worst prognostic factors (cited Dreger et al. as reference 92 and LOE 3iiiD).
