Constantine Tam, MBBS, MD, FRACP, FRCPA from the University of Melbourne, Melbourne, Australia discusses the safety and activity of the BTK inhibitor zanubrutinib (BGB-3111) plus obinutuzumab in follicular lymphoma and chronic lymphocytic leukemia (CLL) patients (NCT02569476). Prof. Tam explains that zanubrutinib is more specific than ibrutinib. When ibrutinib is combined with an antibody, results are often not as good as expected while zanubrutinib has little off-target selectivity. The Phase Ib study evaluates the combination of zanubrutinib and obinutuzumab and has shown that this combination is well-tolerated. Preliminary results are promising with response rates of approximately 70% and a high complete remission rate (CRR) in follicular lymphoma patients suggesting that this may be one of the most active combinations available for relapsed follicular lymphoma.
