Abstract RU 2744852 C2

FIELD: medicine.

SUBSTANCE: set of inventions relates to methods for treating a malignant tumor. A method for treating a subject with a Trk-associated malignant tumor involves (a) administering one or more doses of the first Trk inhibitor to the subject over a period of time where the first Trk inhibitor is sulfate (S)- N-(5-((R)-2-(2,5-difluorophenyl)pyrrolidine-1-yl)pyrazolo[1,5-a]pyrimidine-3-yl)-3-hydroxypyrrolidine-1-carboxamide; and (b) treatment after (a) involving a second Trk inhibitor of the subject where the second Trk inhibitor is (6R, 15R)-9-fluoro-15-methyl-2,11,16,20,21,24-hexaazapentacyclo[16.5.2.02,6.07,12.021,25]pentacose-1(24),7,9,11,18(25),19,22-hepten-17-on where the Trk-associated malignant tumor is resistant to the first Trk inhibitor. Disclosed are also other treatment options for a subject with a Trk-associated malignant tumor.

EFFECT: set of inventions enables treatment of Trk-associated malignant tumors.
