Why is this medication prescribed
Amivantamab-vmjw injection is prescribed to treat non-small cell lung cancer (NSCLC) that has specific genetic mutations in the epidermal growth factor receptor (EGFR) gene. It’s used for patients whose cancer has progressed during or after platinum-based chemotherapy. Amivantamab-vmjw is a monoclonal antibody that targets and binds to the EGFR and MET receptors on cancer cells, helping the immune system to attack and kill these cells.
How should this medicine be used?
Amivantamab-vmjw is an intravenous (IV) infusion used for the treatment of certain types of non-small cell lung cancer (NSCLC) with specific genetic mutations (e.g., EGFR exon 20 insertion mutations). Here are the general guidelines on its use:
- Administration: Amivantamab-vmjw is administered as an IV infusion by a healthcare professional, usually in a clinical setting such as a hospital or infusion center. The infusion is given slowly over a few hours, especially during the initial doses, to monitor for any infusion-related reactions.
- Dosage: The dosing schedule typically involves an initial loading period, where the drug is given once weekly for the first four weeks. After the initial four weeks, the infusion is usually given once every two weeks. The dosage amount is based on the patient’s body weight and other factors determined by the healthcare provider.
- Pre-medications: To reduce the risk of infusion-related reactions, patients may be given pre-medications like antihistamines, corticosteroids, and antipyretics (e.g., acetaminophen) before the infusion.
- Monitoring: Patients should be monitored closely during and after the infusion for any signs of infusion-related reactions, such as fever, chills, nausea, or difficulty breathing. Regular monitoring of skin reactions, eye problems, and lung function is also necessary due to the potential side effects.
- Treatment Duration: The duration of treatment depends on the patient’s response to the therapy, tolerance, and overall health condition. The healthcare provider will determine how long the treatment should continue.
If you have any specific concerns or questions about using Amivantamab-vmjw, it’s always best to consult with your healthcare provider.
