*TAGRISSO + chemotherapy reported the longest statistically significant mOS of an FDA-approved regimen for 1L treatment of patients with EGFRm (exon 19 or exon 21 L858R) locally advanced or metastatic NSCLC.1,2 TAGRISSO + CT (pem/plat) dosing: In cycles 1-4, TAGRISSO 80 mg po qd + pemetrexed (500 mg/m2) q3w + cisplatin (75 mg/m2) or carboplatin (AUC 5) q3w; in cycles 5+, TAGRISSO 80 mg po qd + pemetrexed maintenance (500 mg/m2) q3w until disease progression or unacceptable toxicity. TAGRISSO dosing: 80 mg po qd until disease progression or unacceptable toxicity.1 Overall PFS maturity by IA was 51%.4 §Overall OS maturity was 57%.2 ||Median follow-up for OS (censored patients): 51.2 months (0.2, 60.4) for TAGRISSO + CT (pem/plat) and 51.3 months (0.1, 60.1) for TAGRISSO.2 See the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for detailed recommendations, including other treatment options.

CT (pem/plat), pemetrexed plus platinum-based chemotherapy.
