How does larotrectinib work?

Larotrectinibis used to treat solid tumors (cancers) caused by certain abnormalities in the NTRK gene that have spread, or where surgery to remove the cancer may cause serious complications and there are no acceptable treatment options or the cancer has grown or spread during other treatments.

Larotrectinibis a targeted drug called a tyrosine kinase inhibitor (TKI). Tyrosine kinases are proteins that cells use to send signals to each other to grow. They act as chemical messengers. Blocking these signals can help slow or stop the development of cancer. There are several different tyrosine kinases, Before receiving treatment, patients need to have their cancer cells tested, tests look for changes in these proteins or genes, and tests for the NTRK gene.

Larotrectinib is a kinase inhibitor. Larotrectinibcapsules and oral solutions are formulated using larotrectinibsulfate. The molecular formula of larotinib sulfate isC21H24F2N6O6The molecular weight of sulfate is526.51g/ moles, the molecular weight of the free base is 428.44 grams/ moles. The chemical name is (3S)-N-{5-[(2R)-2-(2, 5-difluorophenyl)-1-pyrrolidinyl]pyrazolo 【1, 5-a]pyrimidine-3-yl}-3-hydroxyl-1-pyrrolidine carboxamide sulfate. Larotrectinib is an off-white to pinkish-yellow solid, non-hygroscopic. The aqueous solubility of larotrectinib at 37ᴼC depends on the pH value (based on the USP solubility description terminology, at pH valueEasily soluble at pH value 6.8).
