Dosage and Administration
2 DOSAGE AND ADMINISTRATION Select patients for treatment with TEPMETKO on the presence of MET ex14 skipping. ( 2.1 , 14 ) Recommended dosage : 450 mg orally once daily with food until disease progression or unacceptable toxicity. ( 2.2 ) 2.1 Patient Selection for METex14 Skipping Alterations Select patients for treatment with TEPMETKO based on the presence of MET exon 14 skipping alterations in plasma or tumor specimens. Testing for the presence of MET exon 14 skipping alterations in plasma specimens is recommended only in patients for whom a tumor biopsy cannot be obtained. If an alteration is not detected in a plasma specimen, re-evaluate the feasibility of biopsy for tumor tissue testing. An FDA-approved test for detection of MET exon 14 skipping alterations in NSCLC for selecting patients for treatment with TEPMETKO is not available. 2.2 Recommended Dosage The recommended dosage of TEPMETKO is 450 mg orally once daily with food [see Clinical Pharmacology (12.3) ] until disease progression or unacceptable toxicity. Instruct patients to take their dose of TEPMETKO at approximately the same time every day and to swallow tablets whole. Do not chew, crush or split tablets. Patients who have difficulty swallowing solids can disperse tablets in water [see Dosage and Administration (2.3) ]. Advise patients not to make up a missed dose within 8 hours of the next scheduled dose. If vomiting occurs after taking a dose of TEPMETKO, advise patients to take the next dose at the scheduled time. 2.3 Administration to Patients Who Have Difficulty Swallowing Solids Place TEPMETKO tablet(s) in a glass containing 30 mL (1 ounce) of non-carbonated water. No other liquids should be used or added. Stir, without crushing, until the tablet(s) is dispersed into small pieces (tablets will not completely dissolve) and drink immediately or within 1 hour. Swallow the tablet dispersion. Do not chew pieces of the tablet. Rinse the glass with an additional 30 mL and drink immediately ensuring no residue remains in the glass and the full dose is administered. If an administration via a naso-gastric tube (with at least 8 French gauge) is required, disperse the tablet(s) in 30 mL of non-carbonated water as described above. Administer the 30 mL of liquid immediately or within 1 hour as per naso-gastric tube manufacturer's instructions. Immediately rinse twice with 30 mL each time to ensure that no residue remains in the glass or syringe and the full dose is administered. 2.4 Dose Modifications for Adverse Reactions The recommended dose reduction of TEPMETKO for the management of adverse reactions is 225 mg orally once daily. Permanently discontinue TEPMETKO in patients who are unable to tolerate 225 mg orally once daily. The recommended dosage modifications of TEPMETKO for adverse reactions are provided in Table 1.

Side Effects (Adverse Reactions)
6 ADVERSE REACTIONS The following adverse reactions are described in greater detail elsewhere in the labeling: Interstitial Lung Disease/Pneumonitis [see Warnings and Precautions (5.1) ] Hepatotoxicity [see Warnings and Precautions (5.2) ] Pancreatic Toxicity [see Warnings and Precautions (5.3) ] Most common adverse reactions (≥ 20%) were edema, nausea, fatigue, musculoskeletal pain, diarrhea, dyspnea, decreased appetite, and rash. The most common Grade 3 to 4 laboratory abnormalities (≥ 2%) were decreased lymphocytes, decreased albumin, decreased sodium, increased gamma-glutamyltransferase, increased amylase, increased lipase, increased ALT, increased AST, and decreased hemoglobin. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact EMD Serono at 1-800-283-8088 ext. 5563 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 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. The pooled safety population described in the WARNINGS AND PRECAUTIONS reflect exposure to TEPMETKO in 506 patients with solid tumors enrolled in five open-label, single-arm studies receiving TEPMETKO as single agent at a dose of 450 mg once daily. This included 313 patients with NSCLC positive for MET ex14 skipping alterations, who received TEPMETKO in VISION. Among 506 patients who received TEPMETKO, 44% were exposed for 6 months or longer, and 22% were exposed for more than one year. The data described below reflect exposure to TEPMETKO 450 mg once daily in 313 patients with metastatic non-small cell lung cancer (NSCLC) with MET ex14 skipping alterations in VISION [see Clinical Studies (14) ]. Serious adverse reactions occurred in 51% of patients who received TEPMETKO. Serious adverse reactions in > 2% of patients included pleural effusion (6%), pneumonia (6%), edema (5%), general health deterioration (3.8%), dyspnea (3.5%), musculoskeletal pain (2.9%), and pulmonary embolism (2.2%). Fatal adverse reactions occurred in 1.9% of patients who received TEPMETKO, including pneumonitis (0.3%), hepatic failure (0.3%), dyspnea from fluid overload (0.3%), pneumonia (0.3%), sepsis (0.3%), and death of unknown cause (0.3%). Permanent discontinuation due to an adverse reaction occurred in 25% of patients who received TEPMETKO. The most frequent adverse reactions (> 1%) leading to permanent discontinuations of TEPMETKO were edema (8%), pleural effusion (1.6%), and general health deterioration (1.6%). Dosage interruptions due to an adverse reaction occurred in 53% of patients who received TEPMETKO. Adverse reactions which required dosage interruption in > 2% of patients who received TEPMETKO included edema (28%), increased blood creatinine (6%), pleural effusion (3.5%), nausea (3.2%), increased ALT (2.9%), pneumonia (2.6%), decreased appetite (2.2%), and dyspnea (2.2%). Dose reductions due to an adverse reaction occurred in 36% of patients who received TEPMETKO. Adverse reactions which required dose reductions in > 2% of patients who received TEPMETKO included edema (22%), increased blood creatinine (2.9%), fatigue (2.2%), and pleural effusion (2.2%). The most common adverse reactions (≥ 20%) in patients who received TEPMETKO were edema, nausea, fatigue, musculoskeletal pain, diarrhea, dyspnea, decreased appetite, and rash. The most common Grade 3 to 4 laboratory abnormalities (≥ 2%) were decreased lymphocytes, decreased albumin, decreased sodium, increased gamma-glutamyltransferase, increased amylase, increased lipase, increased ALT, increased AST, and decreased hemoglobin.

Drug Interactions
7 DRUG INTERACTIONS Certain P-gp substrates : Avoid coadministration of TEPMETKO with P-gp substrates where minimal concentration changes may lead to serious or life-threatening toxicities. ( 7.1 ) 7.1 Effects of TEPMETKO on Other Drugs Certain P-gp Substrates Tepotinib is a P-gp inhibitor. Concomitant use of TEPMETKO increases the concentration of P-gp substrates [see Clinical Pharmacology (12.3) ], which may increase the incidence and severity of adverse reactions of these substrates. Avoid concomitant use of TEPMETKO with certain P-gp substrates where minimal concentration changes may lead to serious or life-threatening toxicities. If concomitant use is unavoidable, reduce the P-gp substrate dosage if recommended in its approved product labeling.

Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary Based on findings in animal studies and the mechanism of action [see Clinical Pharmacology (12.1) ], TEPMETKO can cause fetal harm when administered to a pregnant woman. There are no available data on the use of TEPMETKO in pregnant women. Oral administration of tepotinib to pregnant rabbits during the period of organogenesis resulted in malformations (teratogenicity) and anomalies at maternal exposures less than the human exposure based on area under the curve (AUC) at the 450 mg 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 2% to 4% and 15% to 20%, respectively. Data Animal Data In embryo-fetal development studies, pregnant rabbits received oral doses of 0.5, 5, 25, 50, 150, or 450 mg/kg tepotinib hydrochloride hydrate daily during organogenesis. Severe maternal toxicity occurred at the 450 mg/kg dose (approximately 0.75 times the human exposure at the 450 mg clinical dose). At 150 mg/kg (approximately 0.5 times the human exposure by AUC at the 450 mg clinical dose), two animals aborted and one animal died prematurely; mean fetal body weight was also decreased. A dose-dependent increase of skeletal malformations, including malrotations of fore and/or hind paws with concomitant misshapen scapula and/or malpositioned clavicle and/or calcaneus and/or talus, occurred at doses ≥ 5 mg/kg (approximately 0.003 times the human exposure by AUC at the 450 mg clinical dose); there was also an incidence of spina bifida at the 5 mg/kg dose level.
