Chỉ định & Cách dùng

1 INDICATIONS AND USAGE TABRECTA is indicated for the treatment of adult patients with metastatic non-small cell lung cancer (NSCLC) whose tumors have a mutation that leads to mesenchymal-epithelial transition (MET) exon 14 skipping as detected by an FDA-approved test. TABRECTA is a kinase inhibitor indicated for the treatment of adult patients with metastatic non-small cell lung cancer (NSCLC) whose tumors have a mutation that leads to mesenchymal-epithelial transition (MET) exon 14 skipping as detected by an FDA-approved test.

Cơ chế hoạt động

12.1 Mechanism of Action Capmatinib is a kinase inhibitor that targets MET, including the mutant variant produced by exon 14 skipping. MET exon 14 skipping results in a protein with a missing regulatory domain that reduces its negative regulation leading to increased downstream MET signaling. Capmatinib inhibited cancer cell growth driven by a mutant MET variant lacking exon 14 at clinically achievable concentrations and demonstrated anti-tumor activity in murine tumor xenograft models derived from human lung tumors with either a mutation leading to MET exon 14 skipping or MET amplification. Capmatinib inhibited the phosphorylation of MET triggered by binding of hepatocyte growth factor or by MET amplification, as well as MET-mediated phosphorylation of downstream signaling proteins and proliferation and survival of MET-dependent cancer cells.

12.3 Pharmacokinetics Capmatinib exposure (AUC 0-12h and C max ) increased approximately proportionally over a dose range of 200 mg (0.5 times the recommended dosage) to 400 mg. Capmatinib reached steady-state by day 3 following twice daily dosing, with a mean (% coefficient of variation [%CV]) accumulation ratio of 1.5 (41%). Absorption After administration of TABRECTA 400 mg orally in patients with cancer, capmatinib peak plasma concentrations (C max ) were reached in approximately 1 to 2 hours (T max ). The absorption of capmatinib after oral administration is estimated to be greater than 70%. Effect of Food A high-fat meal (containing approximately 1000 calories and 50% fat) in healthy subjects increased capmatinib AUC 0-INF by 46% with no change in C max compared to under fasted conditions. A low-fat meal (containing approximately 300 calories and 20% fat) in healthy subjects had no clinically meaningful effect on capmatinib exposure. When capmatinib was administered at 400 mg orally twice daily in cancer patients, exposure (AUC 0-12h ) was similar after administration of capmatinib with food and under fasted conditions. Distribution Capmatinib plasma protein binding is 96%, independent of capmatinib concentration. The apparent mean volume of distribution at steady-state is 164 L. The blood-to-plasma ratio was 1.5, but decreased at higher concentrations to 0.9. Elimination The effective elimination half-life of capmatinib is 6.5 hours. The mean (%CV) steady-state apparent clearance of capmatinib is 24 L/hr (82%). Metabolism Capmatinib is primarily metabolized by CYP3A4 and aldehyde oxidase. Excretion Following a single oral administration of radiolabeled-capmatinib to healthy subjects, 78% of the total radioactivity was recovered in feces with 42% as unchanged and 22% was recovered in urine with negligible as unchanged. Specific Populations No clinically significant effects on the pharmacokinetic parameters of capmatinib were identified for the following covariates assessed: age (26 to 90 years), sex, race (White, Asian, Native American, Black, unknown), body weight (35 to 131 kg), mild to moderate renal impairment (baseline CLcr 30 to 89 mL/min by Cockcroft-Gault) and mild, moderate or severe hepatic impairment (Child-Pugh classification). The effect of severe renal impairment (baseline CLcr 15 to 29 mL/min) on capmatinib pharmacokinetics has not been studied. Drug Interaction Studies Clinical Studies and Model-Informed Approaches Strong CYP3A Inhibitors: Coadministration with itraconazole (a strong CYP3A inhibitor) increased capmatinib AUC 0-INF by 42% with no change in capmatinib C max . Strong CYP3A Inducers: Coadministration with rifampicin (a strong CYP3A inducer) decreased capmatinib AUC 0-INF by 67% and decreased C max by 56%. Moderate CYP3A Inducers: Coadministration with efavirenz (a moderate CYP3A inducer) was predicted to decrease capmatinib AUC 0-12h by 44% and decrease C max by 34%. Proton Pump Inhibitors: Coadministration with rabeprazole (a proton pump inhibitor) decreased capmatinib AUC 0-INF by 25% and decreased C max by 38%. Substrates of CYP Enzymes: Coadministration of capmatinib increased caffeine (a CYP1A2 substrate) AUC 0-INF by 134% with no change in its C max . Coadministration of capmatinib had no clinically meaningful effect on exposure of midazolam (a CYP3A substrate). P-gp Substrates: Coadministration of capmatinib increased digoxin (a P-gp substrate) AUC 0-INF by 47% and increased C max by 74%. BCRP Substrates: Coadministration of capmatinib increased rosuvastatin (a BCRP substrate) AUC 0-INF by 108% and increased C max by 204%. In Vitro Studies Transporter Systems: Capmatinib is a substrate of P-gp, but not a substrate of BCRP or MRP2. Capmatinib reversibly inhibits MATE1 and MATE2K, but does not inhibit OATP1B1, OATP1B3, OCT1, OAT1, OAT3, or MRP2.
