摘要

The present invention relates to use of an EZH2 inhibitor combined with a CDK4/6 inhibitor in the preparation of a drug for treating a tumor. Specifically, the EZH2 inhibitor involved in the present invention is selected from a compound shown in formula (I) or a pharmaceutically acceptable salt thereof, and the involved CDK4/6 inhibitor is selected from a compound shown in formula (II) or a pharmaceutically acceptable salt thereof. Compared with a single drug, the combination of the EZH2 inhibitor and the CDK4/6 inhibitor further enhances the anti-tumor effect.
