The LAURA trial (NCT03521154) will evaluate the efficacy and safety of osimertinib as maintenance therapy in patients with locally advanced, unresectable, epidermal growth factor receptor mutation-positive (EGFRm), stage III non–small-cell lung cancer (NSCLC) without disease progression during/following definitive platinum-based chemoradiation therapy (CRT). Eligible patients include adults aged ≥ 18 years (≥ 20 years in Japan) with locally advanced, unresectable, stage III NSCLC with local/central confirmation of an EGFR exon 19 deletion/L858R mutation. Patients must have received ≥ 2 cycles of concurrent/sequential platinum-based CRT, have no investigator-assessed progression, and have creatinine < 1.5 × upper limit of normal and creatinine clearance ≥ 30 mL/min. In this phase III trial, patients will be randomized 2:1 to once-daily osimertinib 80 mg or placebo, until objective radiological disease progression per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, confirmed by blinded independent central review (BICR). The primary objective is to assess the efficacy of osimertinib per BICR-confirmed progression-free survival (PFS). Secondary objectives include central nervous system PFS, overall survival, PFS by mutation status and safety.
