    This is an open-label, multi-center, randomized phase III clinical study conducted in 120 centers in 21 countries around the world

    From July 25, 2015 to November 12, 2018, a total of 290 patients were enrolled, including 143 cases of Ensatinib and 147 cases of Crizotinib


    As of July 1, 2020, the overall intent population (ITT, n=290) mPFS in the ensatinib group was better than that in the crizotinib group, which were 25.




    The objective response rate (ORR) was 74% (95% CI, 66%-81%) in the Ensatinib group and 67% (95% CI, 58%-74%) in the Crizotinib group


    In the revised intention population (mITT of ALK-positive patients confirmed by the central laboratory, n=247 cases, of which 121 cases of Ensatinib

    Among patients without brain metastases in the mITT population, the median PFS of the Ensatinib group and the crizotinib group were NR (25.

    The median OS of the two groups was not reached, and the 2-year OS rates were 78% (95% CI, 69%-84%) and 78% (95% CI, 70%-85%), respectively
