Drug Detail:Tepmetko (Tepotinib)
Generic Name: Tepotinib Hydrochloride 225mg
Dosage Form: tablet
Drug Class: Multikinase inhibitors
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.
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.
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.
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.
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.
| Adverse Reaction | Severity | Dose Modification |
|---|---|---|
| Interstitial Lung Disease (ILD) /Pneumonitis [see Warnings and Precautions (5.1)] | Any grade | Withhold TEPMETKO if ILD is suspected. Permanently discontinue TEPMETKO if ILD is confirmed. |
| Increased ALT and/or AST without increased total bilirubin [see Warnings and Precautions (5.2)] | Grade 3 | Withhold TEPMETKO until recovery to baseline ALT/AST. If recovered to baseline within 7 days, then resume TEPMETKO at the same dose; otherwise resume TEPMETKO at a reduced dose. |
| Grade 4 | Permanently discontinue TEPMETKO. | |
| Increased ALT and/or AST with increased total bilirubin in the absence of cholestasis or hemolysis [see Warnings and Precautions (5.2)] | ALT and/or AST greater than 3 times ULN with total bilirubin greater than 2 times ULN | Permanently discontinue TEPMETKO. |
| Increased total bilirubin without concurrent increased ALT and/or AST [see Warnings and Precautions (5.2)] | Grade 3 | Withhold TEPMETKO until recovery to baseline bilirubin. If recovered to baseline within 7 days, then resume TEPMETKO at a reduced dose; otherwise permanently discontinue. |
| Grade 4 | Permanently discontinue TEPMETKO. | |
| Other adverse reactions [see Adverse Reactions (6.1)] | Grade 2 | Maintain dose level. If intolerable, consider withholding TEPMETKO until resolved, then resume TEPMETKO at a reduced dose. |
| Grade 3 | Withhold TEPMETKO until resolved, then resume TEPMETKO at a reduced dose. | |
| Grade 4 | Permanently discontinue TEPMETKO. |
