Key clinical point: Ibrutinib continued to benefit most treatment-naive patients (58%) with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) in the RESONATE-2 study for ≥5 years, irrespective of baseline characteristics.
Major finding: At a median follow-up of 89.2 months, the median progression-free survival (PFS) and overall survival (OS) were not reached; the 7-year PFS and OS rates were 82% and 94%, respectively. Complete response rates increased from 10% at 1 year to 42% at 5 years and 46% at 7 years. No new safety signals were observed.
Study details: This study analyzed the data of 79 treatment-naive patients aged ≥65 years with CLL or SLL who were randomly assigned to receive ibrutinib in the phase 3 RESONATE-2 trial and its extension study and had continued the treatment for ≥5 years.
Disclosures: This study was sponsored by Pharmacyclics LLC, an AbbVie Company. Some authors reported ties with various organizations, including Pharmacyclics. Two authors declared being employees of, holding stocks in, or having other ownership interests in Pharmacyclics/AbbVie.
