Tabrecta Drug Information

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.

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. If a mutation that leads to MET exon 14 skipping is not detected in a plasma specimen, test tumor tissue if feasible. Information on FDA-approved tests is available at: http://www.fda.gov/CompanionDiagnostics.

Recommended Dosage

The recommended dosage of TABRECTA is 400 mg orally twice daily with or without food. Swallow TABRECTA tablets whole. Do not break, crush or chew the tablets.

If a patient misses or vomits a dose, instruct the patient not to make up the dose, but to take the next dose at its scheduled time.

Dosage Modifications for Adverse Reactions

The recommended dose reductions for the management of adverse reactions are listed in Table 1. Table 1: Recommended TABRECTA Dose Reductions for Adverse Reactions Dose reduction Dose and schedule First 300 mg orally twice daily Second 200 mg orally twice daily Permanently discontinue TABRECTA in patients who are unable to tolerate 200 mg orally twice daily. The recommended dosage modifications of TABRECTA for adverse reactions are provided in Table 2.

Adverse reaction Severity Dosage modification Interstitial Lung Disease (ILD)/Pneumonitis Any grade Permanently discontinue TABRECTA. Increased ALT and/or AST without increased total bilirubin Grade 3 Withhold TABRECTA until recovery to baseline ALT/AST.

Grade 4 Permanently discontinue TABRECTA. Increased ALT and/or AST with increased total bilirubin in the absence of cholestasis or hemolysis ALT and/or AST greater than 3 times ULN with total bilirubin greater than 2 times ULN Permanently discontinue TABRECTA.

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Metastatic Non-Small Cell Lung Cancer The safety of TABRECTA was evaluated in GEOMETRY mono-1. Patients received TABRECTA 400 mg orally twice daily until disease progression or unacceptable toxicity (N = 373).

Among patients who received TABRECTA, 37% were exposed for at least 6 months and 22% were exposed for at least one year. Serious adverse reactions occurred in 53% of patients who received TABRECTA. Fatal adverse reactions occurred in 0.5% of patients who received TABRECTA, including pneumonitis (0.3%) and death, not otherwise specified (0.3%).

Permanent discontinuation of TABRECTA due to an adverse reaction occurred in 17% of patients. Dose interruptions due to an adverse reaction occurred in 57% of patients who received TABRECTA. Adverse reactions requiring dosage interruption in > 2% of patients who received TABRECTA included edema, increased blood creatinine, nausea, increased lipase, vomiting, increased ALT, dyspnea, pneumonia, fatigue, increased amylase, increased AST, musculoskeletal pain, abdominal pain, and increased blood bilirubin.

Dose reductions due to an adverse reaction occurred in 26% of patients who received TABRECTA. The most common adverse reactions (≥ 20%) in patients who received TABRECTA were edema, nausea, musculoskeletal pain, fatigue, vomiting, dyspnea, cough, and decreased appetite. Table 3 summarizes the adverse reactions in GEOMETRY mono-1.

Table 3: Adverse Reactions (≥ 10%) in Patients Who Received TABRECTA in GEOMETRY mono-1 Clinically relevant adverse reactions occurring in < 10% of patients treated with TABRECTA included pruritus (including allergic pruritus), ILD/pneumonitis, cellulitis, acute kidney injury (including renal failure), urticaria, and acute pancreatitis. Table 4 summarizes the laboratory abnormalities in GEOMETRY mono-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. 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.

Coadministration of TABRECTA with a moderate CYP3A inducer may also decrease capmatinib exposure. Decreases in capmatinib exposure may decrease TABRECTA anti-tumor activity.

Effect of TABRECTA on Other Drugs CYP1A2 Substrates Coadministration of TABRECTA increased the exposure of a CYP1A2 substrate, which may increase the adverse reactions of these substrates. If coadministration is unavoidable between TABRECTA and CYP1A2 substrates where minimal concentration changes may lead to serious adverse reactions, decrease the CYP1A2 substrate dosage in accordance with the approved prescribing information. P-glycoprotein (P-gp) and Breast Cancer Resistance Protein (BCRP) Substrates Coadministration of TABRECTA increased the exposure of a P-gp substrate and a BCRP substrate, which may increase the adverse reactions of these substrates.

MATE1 and MATE2K Substrates Coadministration of TABRECTA may increase the exposure of MATE1 and MATE2K substrates, which may increase the adverse reactions of these substrates.

Pregnancy Risk Summary Based on findings from animal studies and its mechanism of action, TABRECTA can cause fetal harm when administered to a pregnant woman. There are no available data on TABRECTA use in pregnant women. Oral administration of capmatinib to pregnant rats and rabbits during the period of organogenesis resulted in malformations at maternal exposures less than the human exposure based on AUC at the 400 mg twice daily clinical dose ( see Data ).

Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is respectively. Data Animal Data In rats, maternal toxicity (reduced body weight gain and food consumption) occurred at 30 mg/kg/day (approximately 1.4 times the human exposure based on AUC at the 400 mg twice daily clinical dose).

Fetal effects included reduced fetal weights, irregular/incomplete ossification, and increased incidences of fetal malformations (e.g., abnormal flexure/inward malrotation of hindpaws/forepaws, thinness of forelimbs, lack of/reduced flexion at the humerus/ulna joints, and narrowed or small tongue) at doses of ≥ 10 mg/kg/day (approximately 0.6 times the human exposure based on AUC at the 400 mg twice daily clinical dose). In rabbits, no maternal effects were detected at doses up to 60 mg/kg/day (approximately 1.5 times the human exposure based on AUC at the 400 mg twice daily clinical dose).

Pediatric Use Safety and effectiveness of TABRECTA in pediatric patients have not been established.
