About this medicine
Dasatinib tablets are a kinase inhibitor. The chemical name for dasatinib is N-(2-chloro-6-methylphenyl)-2-[[6-[4-(2-hydroxyethyl)-1-piperazinyl]-2-methyl-4-pyrimidinyl]amino]-5-thiazolecarboxamide, monohydrate. The molecular formula is C 22 H 26 ClN 7 O 2 S • H 2 O, which corresponds to a formula weight of 506.02 (monohydrate). The anhydrous free base has a molecular weight of 488.01. Dasatinib has the following chemical structure: Dasatinib is a white to off-white powder. The drug substance is soluble in N,N-dimethylformamide and insoluble in acetonitrile. Dasatinib tablets are white to off-white, biconvex, film-coated tablets containing dasatinib, administered orally, with the following inactive ingredients: anhydrous lactose, lactose monohydrate, microcrystalline cellulose, croscarmellose sodium, hydroxypropyl cellulose and magnesium stearate. The tablet coating consists of polyvinyl alcohol, glycerol esters of fatty acids, talc, sodium lauryl sulfate and titanium dioxide. dasatinib-struct.jpg
How it works
12.1 Mechanism of Action Dasatinib, at nanomolar concentrations, inhibits the following kinases: BCR-ABL, SRC family (SRC, LCK, YES, FYN), c-KIT, EPHA2, and PDGFRβ. Based on modeling studies, dasatinib is predicted to bind to multiple conformations of the ABL kinase. In vitro , dasatinib was active in leukemic cell lines representing variants of imatinib mesylate‑-sensitive and resistant disease. Dasatinib inhibited the growth of chronic myeloid leukemia (CML) and acute lymphoblastic leukemia (ALL) cell lines overexpressing BCR-ABL. Under the conditions of the assays, dasatinib could overcome imatinib resistance resulting from BCR-ABL kinase domain mutations, activation of alternate signaling pathways involving the SRC family kinases (LYN, HCK), and multi-drug resistance gene overexpression.
Warnings and cautions
Myelosuppression and Bleeding Events: Severe thrombocytopenia, neutropenia, and anemia may occur. Use caution if used concomitantly with medications that inhibit platelet function or anticoagulants. Monitor complete blood counts regularly. Transfuse and interrupt dasatinib tablets when indicated. ( 2.5 , 5.1 , 5.2 ) Fluid Retention: Fluid retention, sometimes severe, including pleural effusions. Manage with supportive care measures and/or dose modification. ( 2.5 , 5.3 ) Cardiovascular Toxicity: Monitor patients for signs or symptoms and treat appropriately. ( 5.4 ) Pulmonary Arterial Hypertension (PAH): Dasatinib tablets may increase the risk of developing PAH which may be reversible on discontinuation. Consider baseline risk and evaluate patients for signs and symptoms of PAH during treatment. Stop dasatinib tablets if PAH is confirmed. ( 5.5 ) QT Prolongation: Use dasatinib tablets with caution in patients who have or may develop prolongation of the QT interval. ( 5.6 ) Severe Dermatologic Reactions: Individual cases of severe mucocutaneous dermatologic reactions have been reported. ( 5.7 ) Tumor Lysis Syndrome: Tumor lysis syndrome has been reported.

Interactions with other medicines
Strong CYP3A4 Inhibitors: Dose reduction may be necessary. ( 2.3 , 7.1 ) Strong CYP3A4 Inducers: Dose increase may be necessary. ( 2.3 , 7.1 ) Antacids: Avoid simultaneous administration. ( 7.1 ) H 2 Antagonists and Proton Pump Inhibitors: Avoid coadministration. ( 7.1 ) 7.1 Effect of Other Drugs on Dasatinib Strong CYP3A4 Inhibitors The coadministration with strong CYP3A inhibitors may increase dasatinib concentrations [ see Clinical Pharmacology (12.3) ] . Increased dasatinib concentrations may increase the risk of toxicity. Avoid concomitant use of strong CYP3A4 inhibitors. If concomitant administration of a strong CYP3A4 inhibitor cannot be avoided, consider a dasatinib dose reduction [ see Dosage and Administration (2.5) ] . Strong CYP3A4 Inducers The coadministration of dasatinib with strong CYP3A inducers may decrease dasatinib concentrations [ see Clinical Pharmacology (12.3) ] . Decreased dasatinib concentrations may reduce efficacy. Consider alternative drugs with less enzyme induction potential. If concomitant administration of a strong CYP3A4 inducer cannot be avoided, consider a dasatinib dose increase. Gastric Acid Reducing Agents The coadministration of dasatinib with a gastric acid reducing agent may decrease the concentrations of dasatinib. Decreased dasatinib concentrations may reduce efficacy. Do not administer H 2 antagonists or proton pump inhibitors with dasatinib. Consider the use of antacids in place of H 2 antagonists or proton pump inhibitors. Administer the antacid at least 2 hours prior to or 2 hours after the dose of dasatinib. Avoid simultaneous administration of dasatinib with antacids. 7.1 Effect of Other Drugs on Dasatinib Strong CYP3A4 Inhibitors The coadministration with strong CYP3A inhibitors may increase dasatinib concentrations [ see Clinical Pharmacology (12.3) ] .

Use in specific groups
Lactation: Advise women not to breastfeed. ( 8.2 ) 8.1 Pregnancy Risk Summary Based on limited human data, dasatinib can cause fetal harm when administered to a pregnant woman. Adverse pharmacologic effects including hydrops fetalis, fetal leukopenia, and fetal thrombocytopenia have been reported with maternal exposure to dasatinib. Animal reproduction studies in rats have demonstrated extensive mortality during organogenesis, the fetal period, and in neonates. Skeletal malformations were observed in a limited number of surviving rat and rabbit conceptuses. These findings occurred at dasatinib plasma concentrations below those in humans receiving therapeutic doses of dasatinib [see Data] . Advise a pregnant woman of the potential risk to a fetus. The estimated background risk in the U.S. general population of major birth defects is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies. Clinical Considerations Fetal/Neonatal Adverse Reactions Transplacental transfer of dasatinib has been reported. Dasatinib has been measured in fetal plasma and amniotic fluid at concentrations comparable to those in maternal plasma. Hydrops fetalis, fetal leukopenia, and fetal thrombocytopenia have been reported with maternal exposure to dasatinib. These adverse pharmacologic effects on the fetus are similar to adverse reactions observed in adult patients and may result in fetal harm or neonatal death [see Warnings and Precautions ( 5.1 , 5.3 )] . Data Human Data Based on human experience, dasatinib is suspected to cause congenital malformations, including neural tube defects, and harmful pharmacological effects on the fetus when administered during pregnancy. Animal Data In nonclinical studies at plasma concentrations below those observed in humans receiving therapeutic doses of dasatinib, embryo-fetal toxicities were observed in rats and rabbits. Fetal death was observed in rats. In both rats and rabbits, the lowest doses of dasatinib tested (rat: 2.5 mg/kg/day [15 mg/m 2 /day] and rabbit: 0.5 mg/kg/day [6 mg/m 2 /day]) resulted in embryo-fetal toxicities. […]
If too much is taken
Experience with overdose of dasatinib in clinical studies is limited to isolated cases. The highest overdosage of 280 mg per day for 1 week was reported in two patients and both developed severe myelosuppression and bleeding. Since dasatinib is associated with severe myelosuppression [see Warnings and Precautions (5.1) and Adverse Reactions (6.1) ] , monitor patients who ingest more than the recommended dosage closely for myelosuppression and give appropriate supportive treatment. Acute overdose in animals was associated with cardiotoxicity. Evidence of cardiotoxicity included ventricular necrosis and valvular/ventricular/atrial hemorrhage at single doses ≥100 mg/kg (600 mg/m 2 ) in rodents. There was a tendency for increased systolic and diastolic blood pressure in monkeys at single doses ≥10 mg/kg (120 mg/m 2 ).
