Overview
11 DESCRIPTION Capmatinib is a kinase inhibitor. The chemical name is 2-Fluoro- N -methyl-4-[7-(quinolin-6-ylmethyl)imidazo[1,2- b ][1,2,4]triazin-2-yl]benzamide—hydrogen chloride—water (1/2/1). The molecular formula for capmatinib dihydrochloride monohydrate is C 23 H 21 Cl 2 FN 6 O 2 . The relative molecular mass is 503.36 g/mol for the dihydrochloride monohydrate salt and 412.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 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.
Indications
- 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.
Common Doses
- 400 mg
- 300 mg
- 200 mg
Dosage
2 DOSAGE AND ADMINISTRATION Select patients for treatment with TABRECTA based on presence of a mutation that leads to MET exon 14 skipping. ( 2.1 ) Recommended Dosage : 400 mg orally twice daily with or without food. ( 2.2 ) 2.1 Patient Selection Select patients for treatment with TABRECTA based on the presence of a mutation that leads to MET exon 14 skipping in tumor or plasma specimens [see Clinical Studies (14)] . If a mutation that leads to MET exon 14 skipping is not detected in a plasma specimen, test tumor tissue if feasible.
Contraindications
- 4 CONTRAINDICATIONS None. None.
Side Effects
- 6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: ILD/Pneumonitis [see Warnings and Precautions (5.1)] Hepatotoxicity [see Warnings and Precautions (5.2)] Pancreatic Toxicity [see Warnings and Precautions (5.3)] Hypersensitivity reactions [see Warnings and Precautions (5.4)] The most common adverse reactions (≥ 20%) are edema, nausea, musculoskeletal pain, fatigue, vomiting, dyspnea, cough, and decreased appetite.
Interactions
- 7 DRUG INTERACTIONS Strong and Moderate CYP3A Inducers : Avoid concomitant use. ( 7.1 ) 7.1 Effect of Other Drugs on TABRECTA Strong CYP3A Inhibitors Coadministration of TABRECTA with a strong CYP3A inhibitor increased capmatinib exposure, which may increase the incidence and severity of adverse reactions of TABRECTA [see Clinical Pharmacology (12.3)] . Closely monitor patients for adverse reactions during coadministration of TABRECTA with strong CYP3A inhibitors. Strong and Moderate CYP3A Inducers Coadministration of TABRECTA with a strong CYP3A inducer decreased capmatinib exposure.
