Therapeutic Response Statement (Sensitivity)
This therapeutic response statement supports the relationship that EGFR Exon 19 (Deletion) status confers therapeutic sensitivity to Osimertinib in patients with Non-Small Cell Lung Cancer.
This statement is based on a regulatory approval from the Health Service Executive:
As monotherapy for adjuvant treatment after complete tumour resection in adult patients with stage IB-IIIA Non-Small Cell Lung Cancer (NSCLC) whose tumour has epidermal growth factor receptor (EGFR) exon 19 deletions (Ex19del) or exon 21 (L858R) substitution mutations.
