TAGRISSO – Osimertinib uses, dose and side effects


40 mg, 80 mg film-coated tablets

What TAGRISSO is and what it is used for

TAGRISSO contains the active substance osimertinib, which belongs to a group of medicines called protein kinase inhibitors and is used to treat cancer. TAGRISSO is used to treat adults with a type of lung cancer called non-small cell lung cancer. If a test has shown that your cancer has certain changes ( mutations ) in the gene “EGFR” ( epidermal growth factor receptor), your cancer will likely respond to treatment with TAGRISSO. TAGRISSO can be prescribed:

  • after complete removal of your cancer, as a treatment after surgery ( adjuvant treatment)
  • as the first drug cancer treatment, you receive for your cancer that has spread to other parts of the body
  • in some cases, if you have previously been treated with other protein kinase inhibitors for your cancer.

How TAGRISSO works

TAGRISSO works by blocking EGFR and can help slow or stop the growth of your lung cancer. It can also help to shrink the size of the tumor and prevent the tumor from coming back after surgical removal.

  • If you receive TAGRISSO after complete removal of your cancer, it means that your cancer contained a defect ( mutation ) in the EGFR gene, “exon 19 deletion” or “exon 21 substitution mutation”.
  • If TAGRISSO is the first protein kinase inhibitor you receive, it means that your cancer has a defect ( mutation ) in the EGFR gene, so-called “exon 19 deletions” or “exon 21 substitution”.
  • If your cancer worsened while you were taking other protein kinase inhibitors, it means that your cancer has a gene defect ( mutation ) called “T790M”. This defect can render other protein kinase inhibitors no longer effective.

If you have any questions about how this medicine works or why you have been prescribed this medicine, ask your doctor.
