Data from up to 6 years of long-term follow-up shows better progression-free survival, overall survival, objective response rates, and sustained efficacy for patients with chronic lymphocytic leukemia who receive single-agent ibrutinib in earlier lines of treatment, including those with high-risk prognostic factors. According to the poster presented by Paul M. Barr, MD, Division of Hematology/Oncology, Wilmot Cancer Institute, University of Rochester, Rochester, NY, during the 2019 American Society of Hematology Annual Meeting, first-line ibrutinib yielded deeper responses over time with 30% complete responses versus 10% to 12% CR for later lines of treatment.
