MET Exon 14 Skipping
Why Mutations Leading to MET Exon 14 Skipping (METex14) Matter
METex14 is an oncogenic driver in mNSCLC1
METex14 has a prevalence of ~3%, representing ~4,000-5,000 patients with mNSCLC per year in the United States2-10*
NSCLC is a heterogeneous disease with many genomic mutations
- The prevalence of METex14 is similar to that of other genomic mutations, such as ALK fusions (~3%-4%), BRAF mutations (~3%-4%), and ROS1 fusions (~1%-2%)
Patients with METex14 in mNSCLC face a poor prognosis11-13
- Many of these patients may have bone, liver, and brain metastases, which are associated with poor outcomes
*This calculation is based on a 3% prevalence rate and mNSCLC–specific incidence and recurrence data from Kantar Health.
Testing for MET Exon 14 Skipping
Knowledge of METex14 status can inform up-front treatment planning
METex14 testing is a critical component in the treatment of mNSCLC.
- Only patients with METex14 are eligible for biomarker-driven therapy with TABRECTA™ (capmatinib) tablets14
WHOM TO TEST
- Patients with mNSCLC (stage IV)14
WHEN TO TEST
- Test for METex14 upon diagnosis when a patient presents with mNSCLC14,15
HOW TO TEST
- METex14 has a complex biological structure requiring a test that is specifically designed to detect it15,16
- FoundationOne®CDx was validated and optimized to detect the specific mutations leading to MET exon 14 skipping that were studied in the clinical trial for TABRECTA14
- Patients were enrolled in GEOMETRY mono-1 by central confirmation of METex14 using an RNA-based clinical trial assay. A 99% positive percentage agreement was demonstrated when those with evaluable specimens were retested using FoundationOne®CDx (72/73)*
- Information on the FDA-approved test for the detection of METex14 in NSCLC is available at FDA.gov/CompanionDiagnostics or FoundationMedicine.com/F1CDx
CMS instituted an NCD for FDA-approved NGS tests, including FoundationOne®CDx, in March 201817
Assess for METex14 in mNSCLC in:
- Patients with stage IV disease
- Patients who have not received prior therapy or have progressed on treatment
FoundationOne®CDx is a qualitative next-generation sequencing based in vitro diagnostic test for advanced cancer patients with solid tumors and is for prescription use only. The test analyzes 324 genes as well as genomic signatures including microsatellite instability (MSI) and tumor mutational burden (TMB) and is a companion diagnostic to identify patients who may benefit from treatment with specific therapies in accordance with the approved therapeutic product labeling. Additional genomic findings may be reported and are not prescriptive or conclusive for labeled use of any specific therapeutic product. Use of the test does not guarantee a patient will be matched to a treatment. A negative result does not rule out the presence of an alteration. Some patients may require a biopsy. For the complete label, including companion diagnostic indications and important risk information, please visit www.F1CDxLabel.com.

*Of 78 specimens available to be retested, only 73 were evaluable.

TABRECTA™ (capmatinib) tablets 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.
This indication is approved under accelerated approval based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.
Important Safety Information
Interstitial Lung Disease (ILD)/Pneumonitis. ILD/pneumonitis, which can be fatal, occurred in patients treated with TABRECTA. ILD/pneumonitis occurred in 4.5% of patients treated with TABRECTA in the GEOMETRY mono-1 study, with 1.8% of patients experiencing grade 3 ILD/pneumonitis and 1 patient experiencing death (0.3%). Eight patients (2.4%) discontinued TABRECTA due to ILD/pneumonitis.
Monitor for new or worsening pulmonary symptoms indicative of ILD/pneumonitis (eg, dyspnea, cough, fever). Immediately withhold TABRECTA in patients with suspected ILD/pneumonitis and permanently discontinue if no other potential causes of ILD/pneumonitis are identified.
Hepatotoxicity. Hepatotoxicity occurred in patients treated with TABRECTA. Increased alanine aminotransferase (ALT)/aspartate aminotransferase (AST) occurred in 13% of patients treated with TABRECTA in GEOMETRY mono-1. Grade 3 or 4 increased ALT/AST occurred in 6% of patients. Three patients (0.9%) discontinued TABRECTA due to increased ALT/AST.
Monitor liver function tests (including ALT, AST, and total bilirubin) prior to the start of TABRECTA, every 2 weeks during the first 3 months of treatment, then once a month or as clinically indicated, with more frequent testing in patients who develop increased transaminases or bilirubin. Based on the severity of the adverse reaction, withhold, reduce dose, or permanently discontinue TABRECTA.
Risk of Photosensitivity. Based on findings from animal studies, there is a potential risk of photosensitivity reactions with TABRECTA. In GEOMETRY mono-1, it was recommended that patients use precautionary measures against ultraviolet exposure, such as use of sunscreen or protective clothing, during treatment with TABRECTA. Advise patients to limit direct ultraviolet exposure during treatment with TABRECTA.
Embryo-Fetal Toxicity. Based on findings from animal studies and its mechanism of action, TABRECTA can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with TABRECTA and for 1 week after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with TABRECTA and for 1 week after the last dose.
Most Common Adverse Reactions. The most common adverse reactions (≥20%) were peripheral edema (52%), nausea (44%), fatigue (32%), vomiting (28%), dyspnea (24%), and decreased appetite (21%). The most common grade 3 adverse reactions (≥2%) were peripheral edema (9%), fatigue (8%), dyspnea (7%), nausea (2.7%), vomiting (2.4%), and noncardiac chest pain (2.1%). Grade 4 dyspnea was reported in 0.6% of patients.
Clinically Relevant Adverse Reactions. Clinically relevant adverse reactions observed in <10% of patients were pruritus (allergic and generalized), ILD/pneumonitis, cellulitis, acute kidney injury (including renal failure), urticaria, and acute pancreatitis.
Laboratory Abnormalities. Select laboratory abnormalities (≥20%) worsening from baseline in patients who received TABRECTA were decreased albumin (68%), increased creatinine (62%), decreased lymphocytes (44%), increased ALT (37%), increased alkaline phosphatase (32%), increased amylase (31%), increased gamma-glutamyltransferase (29%), increased lipase (26%), increased AST (25%), decreased hemoglobin (24%), decreased leukocytes (23%), decreased sodium (23%), decreased phosphate (23%), increased potassium (23%), and decreased glucose (21%).
