All patients, except for PCP#4 received ibrutinib as first-line therapy.
ALC, absolute lymphocyte count; ANC, absolute neutrophil count; CD4, absolute CD4+ T-cell count; FISH, fluorescence in situ hybridization (Del17p: deletion 17p, Tri12: trisomy 12); IgG, immunoglobulin G; IGHV, Ig heavy chain variable (M: mutated, U: unmutated); NK, natural killer; S aureus, Staphylococcus aureus; TMP/SMX, trimethoprim/sulfamethoxazole; TT-PCP, time from the start of ibrutinib until the first diagnosis of PCP.
ALC and ANC were assessed within 1 week prior to PCP diagnosis. Lymphocyte and Ig subsets were assessed within 2 weeks prior to PCP diagnosis.
No lymphocytes subset or Ig data are available between starting ibrutinib and PCP diagnosis for the 2 patients diagnosed at 2 months on single-agent ibritinib.
Patient was receiving IVIG replacement.
Patient was previously treated with two lines of therapy prior to ibrutinib. All other patients were previously untreated for CLL prior to ibrutinib.
