Ibrutinib, a Bruton’s tyrosine kinase inhibitor, is already approved as a single agent for WM. The addition of rituximab to the indication is based on positive results from the phase 3 INNOVATE study. In particular, the trial showed a superior progression-free survival rate at 30 months for the ibrutinib-rituximab combination at 82%, compared with placebo plus rituximab at 28% (N Engl J Med. 2018;378:2399-410).

The study’s lead investigator, Meletios A. Dimopoulos, MD, called the combination a “new standard of care” for WM at the recent annual meeting of the American Society of Clinical Oncology.

Ibrutinib, marketed as Imbruvica, is jointly developed and commercialized by Pharmacyclics and Janssen Biotech.
