Both RWDs confirmed poorer prognosis for 1L osimertinib-treated patients with L858R vs ex19del. MDACC cohort showed a 12-mo PFS rate of 63% for L858R (n=45) vs 82% for ex19del (n=60); mPFS was immature….In both RWDs, 1L osimertinib-treated patients with L858R-driven NSCLC had poorer outcomes vs ex19del, consistent with osimertinib’s weaker activity on L858R.

Excerpt:
Using real-world data from the Netherlands Cancer Registry (NCR) we assessed patients diagnosed with stage IV NSCLC with del19 or L858R mutation....Median OS was superior for del19 versus L858R (28.4 months (95% CI 25.6-30.6) versus 17.7 months (95% CI 16.1-19.5), p < 0.001....Only in the subgroup of patients with del19 and baseline BM, a benefit was observed for treatment with osimertinib....In this nationwide real-world cohort, survival of Dutch patients with advanced NSCLC and an EGFR del19 mutation was superior versus those harboring an L858R mutation. Osimertinib performed only better as first-line treatment in patients with del19 and BM.
