With increasing biomarker-driven cancer treatments, TEPMETKO benefits from growing adoption in precision oncology. Competition from other MET inhibitors like TABRECTA (capmatinib) exists, but TEPMETKO's once-daily dosing and efficacy profile offer differentiation. LAS VEGAS, March 6, 2025 /PRNewswire/ -- DelveInsight's " TEPMETKO Market Size, Forecast, and Market Insight Report" highlights the details around TEPMETKO, a kinase inhibitor indicated for the treatment of adult patients with metastatic NSCLC harboring MET exon 14 skipping alterations. The report provides product descriptions, patent details, and competitor products (marketed and emerging therapies) of TEPMETKO. The report also highlights the historical and forecasted sales from 2020 to 2034 segmented into 7MM [the United States, the EU4 (Germany, France, Italy, and Spain), the United Kingdom, and Japan]. EMD Serono's TEPMETKO (tepotinib) Overview TEPMETKO is a kinase inhibitor prescribed for adult patients with metastatic non-small cell lung cancer (NSCLC) carrying MET exon 14 skipping alterations. The active component is Tepotinib (as hydrochloride monohydrate), administered orally. Patients should be cautioned about the heightened risk of severe or fatal interstitial lung disease/pneumonitis, liver toxicity, and potential embryo-fetal toxicity, necessitating effective contraception during and shortly after treatment. Tepotinib specifically targets MET, including variants with exon 14 skipping mutations. It blocks HGF-dependent and independent MET phosphorylation, disrupting MET-driven signaling pathways. Additionally, at clinically relevant concentrations, Tepotinib inhibits melatonin 2 and imidazoline 1 receptors. In vitro studies show that it suppresses tumor cell proliferation, anchorage-independent growth, and migration of MET-dependent cancer cells. In mouse models with MET-driven tumors, including those with MET exon 14 skipping alterations, Tepotinib reduced tumor growth, sustained MET phosphorylation inhibition, and, in one case, decreased metastasis formation. The recommended dose of TEPMETKO is 450 mg taken orally once daily until disease progression or intolerable toxicity occurs. Patients should take it at the same time each day, swallowing tablets whole without chewing, crushing, or splitting them. If a dose is missed and less than eight hours remain until the next scheduled dose, patients should skip it. In cases of vomiting after taking TEPMETKO, the next dose should be taken at the usual time. Learn more about TEPMETKO projected market size for NSCLC @ TEPMETKO Market Potential Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, accounting for 81% of all diagnosed cases. Early detection greatly improves outcomes, but diagnosing NSCLC and other lung cancers is challenging because their symptoms are often mistaken for common illnesses or the long-term effects of smoking. Consequently, 80% of NSCLC cases are already at advanced stages by the time they are identified, making treatment more difficult. Around 80% of EGFR mutations in NSCLC involve either exon 19 deletions or the exon 21 L858R substitution, both of which are classified as sensitizing mutations. Until the last decade, chemotherapy was the primary treatment for advanced and metastatic lung cancer. However, this changed in 2015 with the approval of the first immune checkpoint inhibitor (ICI), KEYTRUDA (pembrolizumab), as a second-line therapy for advanced cases. This was followed by TECENTRIQ (atezolizumab) in 2016. Both therapies were later approved for first-line treatment, broadening their use to a larger patient population. In 2020, the combination of OPDIVO (nivolumab) and ipilimumab also received approval as a first-line treatment for metastatic NSCLC. According to DelveInsight, the NSCLC market size across the 7MM is projected to grow from USD 30 billion in 2024, with a substantial CAGR through 2034. This growth is largely driven by the introduction of emerging therapies during the forecast period (2025–2034).
