Gilternib 40 mg (Gilteritinib)

Description

COMPOSITION
Gilternib tablet: Each film coated tablet contains Gilteritinib Fumarate INN equivalent to Gilteritinib 40 mg.
PHARMACOLOGY
Gilteritinib is a small molecule that inhibits multiple receptor tyrosine kinases, including FMS-like tyrosine kinase 3 (FLT3). Gilteritinib demonstrated the ability to inhibit FLT3 receptor signaling and proliferation in cells exogenously expressing FLT3 including FLT3-ITD, tyrosine kinase domain mutations (TKD) FLT3-D835Y and FLT3-ITD-D835Y, and it induced apoptosis in leukemic cells expressing FLT3-ITD.
Pharmacokinetic
The following pharmacokinetic parameters were observed following administration of Gilteritinib 120 mg once daily, unless otherwise specified. Gilteritinib exposure (Cmax and AUC24) increases proportionally with once daily doses ranging from 20 mg to 450 mg (0.17 to 3.75 times the recommended dosage) in patients with relapsed or refractory AML. Gilteritinib is primarily metabolized via CYP3A4 in vitro. At steady state, the primary metabolites in humans include M17 (formed via N-dealkylation and oxidation), M16 and M10 (both formed via N-dealkylation). None of these 3 metabolites exceeded 10% of overall parent exposure.
INDICATIONS AND USAGE
Gilteritinib is indicated for the treatment of adult patients who have relapsed or refractory acute myeloid leukemia (AML) with a FMS-like tyrosine kinase 3 (FLT3) mutation as detected by an FDA-approved test.
DOSAGE AND ADMINISTRATION
The recommended starting dose of Gilteritinib is 120 mg orally once daily with or without food. Response may be delayed. In the absence of disease progression or unacceptable toxicity, treatment for a minimum of 6 months is recommended to allow time for a clinical response. Do not break or crush Gilteritinib tablets. Administer Gilteritinib tablets orally about the same time each day. If a dose of Gilteritinib is missed or not taken at the usual time, administer the dose as soon as possible on the same day, and at least 12 hours prior to the next scheduled dose. Return to the normal schedule the following day. Do not administer 2 doses within 12 hours.
