Ibrutinib more effective than traditional chemotherapy in older untreated patients with CLL

In continuation of my update on ibrutinib

A multi-center, international, randomized, Phase III study of older untreated patients with chronic lymphocytic leukemia (CLL) demonstrated that ibrutinib, a kinase inhibitor, is significantly more effective than traditional chemotherapy with chlorambucil.

The study, which followed 269 patients, revealed a 24-month overall survival rate of 97.8 percent for patients taking ibrutinib versus 85.3 percent for those on chlorambucil. Minor adverse effects were reported.

Results from the study, led by Jan Burger, M.D., Ph.D. from The University of Texas MD Anderson Cancer Center, were published in today's online issue of the New England Journal of Medicine.

"Ibrutinib was superior to chlorambucil in CLL patients with no prior treatment, as measured by progression-free survival, overall survival, and response" said Burger, an associate professor in Leukemia. "The study also revealed significant improvements in hemoglobin and platelet levels."
