This clinical trial is focused on studying a type of lung cancer known as EGFR-mutated Advanced or Metastatic Non-small Cell Lung Cancer (NSCLC). The study aims to evaluate the effectiveness of different medications in reducing reactions that may occur during the infusion of a treatment called Amivantamab. Amivantamab is a special type of medication known as an EGFR-MET bispecific antibody, which targets specific proteins involved in the growth of cancer cells. The trial will test three different medications: Methotrexate, Dexamethasone, and Montelukast, to see if they can help prevent these infusion-related reactions.
The purpose of the study is to assess whether taking Methotrexate, Dexamethasone, or Montelukast before receiving Amivantamab can reduce the frequency or severity of these reactions. Methotrexate is given as a solution for injection, Dexamethasone is taken as a tablet, and Montelukast is also taken as a tablet. Participants in the study will receive one of these medications before their Amivantamab infusion. The study will monitor the participants to see how well these medications work in preventing reactions during the first dose of Amivantamab.
The study will involve participants who have previously been treated with a medication called Osimertinib and chemotherapy. The trial will take place over a period of time, with participants receiving the study medications and being observed for any reactions. The goal is to find out if these medications can make the infusion process safer and more comfortable for patients with this type of lung cancer.
