What are the common side effects of tepotinib?

Tepotinib is a targeted therapy for the treatment of advanced non-small cell lung cancer carrying exon skipping mutations in exon 14 of the MET gene. Like many other targeted therapies, tepotinib can cause a variety of side effects. Understanding these side effects can help patients and healthcare teams better manage their treatment.

1. Digestive side effects: Many patients may experience nausea and occasional vomiting while taking tepotinib. These symptoms can often be relieved with dietary modifications and anti-nausea medications. Diarrhea is one of the common side effects of tepotinib. Patients should maintain adequate fluid intake and use antidiarrheal medications when necessary. In severe cases, dose adjustment or medication suspension may be necessary. Some patients may experience decreased appetite, leading to weight loss. Nutritional support and dietary modification can help alleviate this problem.

2. Abnormal liver function: Tepotinib may cause abnormal liver function, manifested by an increase in liver enzymes (such as ALT and AST). Regular monitoring of liver function is necessary and if liver enzyme levels are significantly elevated, dose adjustment or medication suspension may be necessary.

3. Eedema: Eedema, especially in the lower limbs, is another common side effect. Patients may experience swelling in their legs or ankles. Mild edema can be relieved by elevating the legs and using compression stockings, but severe edema may require medical intervention.

4. Skin reactions: Skin reactions, such as rash and itching, are also common during tepotinib treatment. These symptoms are usually mild and can be relieved with topical medications or antihistamines. If the skin reaction is severe, the medication may need to be discontinued.

5. Fatigue and Fatigue: Fatigue and fatigue are common side effects of many cancer treatment drugs. Patients should ensure adequate rest, avoid overexertion, and engage in moderate exercise to improve physical strength when possible.

6. Hematological abnormalities: Some patients may develop hematological abnormalities, such as anemia or leukopenia. Regular blood tests can help detect and manage these problems promptly.

7. Abnormal renal function: Although less common, tepotinib may also affect renal function. Therefore, patients should undergo regular renal function monitoring during treatment.

Overall, management of tepotinib side effects requires the collaboration of a multidisciplinary team, including oncologists, nurses, and pharmacists. Patients should promptly report any discomfort or new symptoms so that the medical team can promptly adjust the treatment plan to ensure the best treatment effect and quality of life.
