Response to ibrutinib in chronic lymphocytic leukemia improves in quality with time.

ABSTRACT

Unlike chemoimmunotherapy regimens, which are given for a defined period, ibrutinib, a first-in-class Bruton's kinase inhibitor, allows most patients with CLL to remain on treatment for an extended period. Our experience, supported by sequential CT scan images, suggests that long-term ibrutinib promotes a high response rate that improves in quality with time.
