Abstract: An object of the present invention is to provide a combination therapy in which an antitumor effect is enhanced as compared to when a Trk inhibitor or any of various kinase inhibitors is administered alone. A Trk inhibitor, particularly, a compound represented by General Formula (I): wherein all symbols have the same meanings as symbols described in this specification, a salt thereof, an N-oxide thereof, a solvate thereof, or a prodrug thereof is useful as an active ingredient of a cancer therapeutic agent used in combination with one or more drugs selected from the group consisting of an MEK inhibitor, a CDK4/6 inhibitor, an EGFR inhibitor and a JAK1/2 inhibitor.

Abstract: To provide a medicament which shows more remarkable effect in treatment of activated B-cell like diffuse large B-cell lymphoma ABC-DLBCL than the existing Btk inhibitor, and is excellent in safety. The present compound exhibits more remarkable effect in treatment of activated B-cell like diffuse large B-cell lymphoma (ABC-DLBCL) patients, inter alia, ABC-DLBCL patients having CD79B wild-type gene background than the existing Btk inhibitor, and therefore, it can attain the object of the present invention.
