Precautions of Tepotinib

1. Interstitial Lung Disease (ILD)/Pneumonitis

Monitor patients for new or worsening pulmonary symptoms indicative of ILD/pneumonitis (e.g., dyspnea, cough, fever). Immediately withhold Tepotinib in patients with suspected ILD/pneumonitis  and permanently discontinue if no other potential causes of ILD/pneumonitis are identified.

2. Hepatotoxicity

Monitor liver function tests (including ALT, AST, and total bilirubin) prior to the start of Tepotinib, 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, dose reduce, or permanently discontinue Tepotinib.

3 Embryo-Fetal Toxicity

Based on findings in animal studies and its mechanism of action Tepotinib can cause fetal harm when administered to a pregnant woman. Oral administration of tepotinib to pregnant rabbits during the period of organogenesis resulted in malformations (teratogenicity) and anomalies at exposures less than the human exposure based on area under the curve (AUC) at the 450 mg daily clinical dose. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential or males with female partners of reproductive potential to use effective contraception during treatment with Tepotinib and  for one week after the final dose.
