Long-term efficacy and safety of first-line ibrutinib treatment for patients with CLL/SLL: 5 years of follow-up from the phase 3 RESONATE-2 study

RESONATE-2 is a phase 3 study of first-line ibrutinib versus chlorambucil in chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). Patients aged ≥65 years ( n = 269) were randomized 1:1 to once-daily ibrutinib 420 mg continuously or chlorambucil 0.5–0.8 mg/kg for ≤12 cycles.
