Osimertinib, also known by its brand name Osimert, is an oral tyrosine kinase inhibitor (TKI) that is primarily used to treat patients with metastatic epidermal growth factor receptor (EGFR) T790M mutation-positive non-small cell lung cancer (NSCLC). Approved by the FDA in 2015, Osimertinib has proven to be an effective treatment option, prolonging progression-free survival and improving overall quality of life for patients. This comprehensive guide will cover the essential dos and don'ts of Osimertinib use, helping patients optimize their Osimert 80mg experience.

  1. Understanding Osimertinib

Before delving into the dos and don'ts of Osimertinib, it's crucial to have a basic understanding of the medication and its role in treating NSCLC.

  1. What is Osimertinib?

Osimertinib is a third-generation EGFR-TKI, targeting specific mutations in the EGFR gene that drive tumor growth in NSCLC. It selectively and irreversibly blocks the activity of the EGFR T790M mutation, which is commonly associated with acquired resistance to first and second-generation EGFR-TKIs such as Gefitinib and Afatinib.

  1. Who Can Benefit from Osimertinib?

Osimertinib is designed for patients with metastatic EGFR T790M mutation-positive NSCLC. Patients must have their tumor tissue tested for the presence of the T790M mutation before starting treatment with Osimert. The medication is used in cases where the cancer has progressed on or after EGFR-TKI therapy.
