A Study to Investigate Safety and Efficacy of Osimertinib and Amivantamab in Participants With Non-small Cell Lung Cancer With Common Epidermal Growth Factor Receptor Mutations

Histologically or cytologically documented non-squamous NSCLC. NSCLC of mixed histology is allowed.Newly diagnosed locally advanced or metastatic NSCLC or recurrent non-squamous NSCLC, not amenable to curative surgery or radiotherapy. WHO PS of 0 to 1 with no deterioration over the 2 weeks prior to enrolment. Minimum life expectancy > 12 weeks at Day 1. Confirmation by the locally accredited laboratory that the tumour harbours one of the 2 common EGFRm known to be associated with (Epidermal Growth Factor Receptor- Tyrosine Kinase Inhibitor) EGFR-TKI sensitivity. At least 1 lesion that can be accurately measured at baseline as ≥10 mm in the longest diameter with computed tomography (CT) or magnetic resonance imaging (MRI) and that is suitable for accurate repeated measurements. Contraceptive use by males or females should be consistent with local regulations
