This trial shows that zanubrutinib, a tablet taken twice daily, is very active in chronic lymphocytic leukaemia. The response rates were very high and the CLL came under good control in nearly all the patients. The good news for patients is that zanubrutinib was well tolerated with very few having to stop the tablets due to side-effects. While longer follow-up is needed, most patients remain on zanubrutinib with their CLL under very good control.
