Frequently asked questions about Tepotinib

What is Tepotinib used for?

Tepotinib is an investigational small molecule being studied for advanced Stage IIIB/IV non-small cell lung cancer (NSCLC) with MET exon 14 (METex14) skipping alterations or MET amplification, as well as for non-small cell lung cancer, carcinoma, and hepatocellular carcinoma. It is currently in Phase 2 clinical development.

What does Tepotinib target?

Tepotinib is a kinase inhibitor, belonging to the -tinib class of drugs. It is being investigated for its activity against tumors with MET exon 14 skipping alterations or MET amplification in non-small cell lung cancer.

Who makes Tepotinib?

Tepotinib is being developed by Merck & Company, Inc., which trades under the ticker MRK. The company is conducting clinical trials to evaluate the drug's safety and efficacy in oncology indications.

What phase is Tepotinib in?

Tepotinib is in Phase 2 clinical development. It is an investigational drug and has not been approved by regulatory authorities. The drug is being studied in patients with advanced non-small cell lung cancer and other solid tumors.

What clinical trials is Tepotinib in?

Tepotinib has been studied in four clinical trials, all of which are completed. These include NCT03492437, NCT03531762, NCT03628339, and NCT05213481, which evaluated drug interactions in healthy participants. The trials were conducted in Germany and enrolled a total of 62 healthy volunteers.

Is Tepotinib the same as other MET inhibitors?

Tepotinib is a distinct investigational kinase inhibitor targeting MET alterations. It is being developed specifically for cancers with MET exon 14 skipping alterations or MET amplification, and is not the same as other approved or investigational MET inhibitors.
