Abstract

A method of treating diffuse large B-cell lymphoma comprising administering to a patient a pharmaceutically acceptable amount of a composition comprising a thienotriazolodiazepine compound, said thienotriazolodiazepine compound being represented by Formula (I), wherein R₁ is alkyl having a carbon number of 1-4, R₂ is a hydrogen atom; a halogen atom; or alkyl having a carbon number of 1-4 optionally substituted by a halogen atom or a hydroxyl group, R₃ is a halogen atom; phenyl optionally substituted by a halogen atom, alkyl having a carbon number of 1-4, alkoxy having a carbon number of 1-4 or cyano; —NR₅—(CH₂)_m—R₆ wherein R₅ is a hydrogen atom or alkyl having a carbon number of 1-4, m is an integer of 0-4, and R₆ is phenyl or pyridyl optionally substituted by a halogen atom; or —NR₇—CO—(CH₂)_n—R₈ wherein R₇ is a hydrogen atom or alkyl having a carbon number of 1-4, n is an integer of 0-2, and R₈ is phenyl or pyridyl optionally substituted by a halogen atom, and R₄ is —(CH₂)_a—CO—NH—R₉ wherein a is an integer of 1-4, and R₉ is alkyl having a carbon number of 1-4; hydroxyalkyl having a carbon number of 1-4; alkoxy having a carbon number of 1-4; or phenyl or pyridyl optionally substituted by alkyl having a carbon number of 1-4, alkoxy having a carbon number of 1-4, amino or a hydroxyl group or —(CH₂)_b—COOR₁₀ wherein b is an integer of 1-4, and R₁₀ is alkyl having a carbon number of 1-4, or a pharmaceutically acceptable salt thereof or a hydrate or solvate thereof, wherein the patient has activated B-cell diffuse large B-cell lymphoma.
