Abstract: A method of treating lymphoblastic leukemia, acute myeloid leukemia, BCR-ABL positive acute lymphoblastic leukemia or CD34 positive acute myeloid leukemia comprising the step of administering to a patient a pharmaceutically acceptable amount of a composition comprising a thienotriazolodiazepine compound according to Formula (1) as a solid dispersion wherein X is a halogen, R1 is C1-C4 alkyl, R2 is C1-C4 alkyl, a is an integer of 1-4, R3 is C1-C4 alkyl, C1-C4 hydroxyalkyl, C1-C4 alkoxy, phenyl optionally having substituent(s), or heteroaryl optionally having substituent(s), a pharmaceutically acceptable salt thereof or a hydrate thereof; and a pharmaceutically acceptable polymer. In one embodiment, the pharmaceutically acceptable polymer is HPMCAS.

Abstract: A method of treating acute myeloid leukemia or acute lymphoid leukemia in a mammal comprising the step of: administering a pharmaceutically acceptable amount of a thienotriazolodiazepine compound represented by the following Formula (1): 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 h
