AstraZeneca Plc’s Bruton tyrosine kinase inhibitor Calquence, already approved in the US for mantle cell lymphoma, has delivered positive results in a Phase 3 trial of previously-treated patients with chronic lymphocytic leukaemia. The trial showed a statistically-significant and clinically-meaningful improvement in progression-free survival and will stop early, the company announced on 6 May. Calquence was administered as a monotherapy and compared with a combination of rituximab and a physician’s choice of either idelalisib or bendamustine.
