Dave Fredrickson, Executive Vice President, Oncology Business Unit, AstraZeneca, said: “The approval of Calquence in Japan for those with treatment-naïve chronic lymphocytic leukaemia now offers more patients a next-generation Bruton’s tyrosine kinase inhibitor that has proven longer-term efficacy and tolerability compared to standards of care. With this approval, people living with chronic lymphocytic leukaemia in Japan can now potentially benefit from our medicine in an earlier setting.”
