Tagrisso uses
Tagrisso is mainly used in the treatment of patients with metastatic epidermal growth factor receptor (EGFR) T790M mutation-positive non-small cell lung cancer (NSCLC) who have progressed on or after EGFR TKI therapy. It is also used for patients with metastatic NSCLC whose tumors have EGFR exon 19 deletions or exon 21L858R mutations. Further, it can be an adjuvant therapy after tumor resection in patients with NSCLC whose tumors harbor the same EGFR mutations.
