One of the major reasons for having cancer nowadays is mutation in our body, specifically genetic mutation. However, scientists have identified a rare genetic mutation called NTRK gene fusions, which cause the production of abnormal TRK proteins. Since these proteins continuously giving signals to cancer cells to grow and divide in an uncontrolled manner.
What is Larotrectinib?
It is a targeted cancer medication that works as a selective inhibitor of tropomyosin kinase receptors (TrkA, TrkB, and TrkC). However, doctors approve its use for adult and pediatric patients with solid tumors that have an NTRK (neurotrophic receptor tyrosine kinase) gene fusion, particularly when tumors are metastatic or cannot be surgically removed.
What are NTRK gene fusion?
NTRK gene fusions a rare genetic alterations that occurs when an NTRK1, NTRK2, or NTRK3 gene breaks and fuses with another unrelated gene. Hence, this creates abnormal, chimeric TRK fusion proteins that drive uncontrolled cell growth and cancer development. Therefore, they function as tumor-agnostic biomarkers, appearing in various solid tumors and allowing doctors to treat them with specific TRK inhibitors.
However, NTRK gene fusions may impact both adults and children’s, including salivary gland cancer, intestines cancer, lung cancer, thyroid cancer, and some rare pediatric cancers, such as salivary gland cancer, intestines cancer, lung cancer, and thyroid cancer.
What Is the Recommended Dosage of medicine?
Doctors use it to treat solid tumors that carry an NTRK gene fusion and guide its use under professional supervision. Take Vitrakvi 100 mg Capsule orally twice daily, with or without food, and continue until the disease progresses or you experience unacceptable side effects.
What Is Vitrakvi 25mg Capsule Used For?
- Tumor-Agnostic Treatment: Larotrectinib is approved for treating various solid tumor such as lung, thyroid, salivary gland, soft tissue sarcoma that contains an gene alteration called NTRK gene fusion-positive.
- Advanced Cancer: It is used for metastatic or locally advanced solid tumors when surgery causes severe complications.
- Pediatric & Adult Use: Approved for both adults and children, including infants who are about 4 weeks of age and older.
- Specific Genetic Mutation: To confirm the presence of an NTRK gene fusion before treatment it requires a diagnostic test.
What important precautions should you take?
- Prescription Required: It is a prescription based medication thus, it must be taken exactly as prescribed by a doctor.
- Liver Function: A healthcare professional needed to conduct blood tests before and during treatment to monitor your liver function.
- Pregnancy/Breastfeeding: Taking this medication during pregnancy can harm the unborn baby. Therefore, women of childbearing potential and men with partners who can get pregnant must use effective birth control during treatment and for one week after the last dose. Thus, do not breastfeed while using this medicine.
- Drug Interactions: Grapefruit products can interact with this medication and thus it should be avoided.
Which Side Effects Should I Expect with this medicine?
Side effects come with each medicine we take some are common while some are severe side effects. The most common side effects of this medication (which may affect more than 1 in 5 people) include:
- Tiredness
- Dizziness
- Nausea and vomiting
- Constipation or diarrhea
- Coughing
- Muscle and bone pain
- Abnormal liver function tests
- Low red blood cell counts (anemia)
Hence, patients should stay in touch with their doctors to avoid having any complication such as having any severe side effects of medicine while they are on the treatment.
Conclusion
In conclusion, the concept of precision medicine has recently received attention as one of the newest ways to personalize cancer treatment. This type of therapy is effective for targeting specific types of NTRK gene fusions and offers patients with tumors that test positively for this mutation a viable option. Genetic testing, dosages, and monitoring by physicians are three key components to achieving optimal results and being safe when using this medication in patients.
