About the study

AMAZE-lung is a multicenter single-arm phase II trial. The protocol treatment consists of amivantamab, lazertinib and bevacizumab (Zirabev®), given in a three-weekly regimen. The primary objective of the trial is to assess the efficacy of amivantamab and bevacizumab added to continued treatment with the third-generation EGFR-TKI lazertinib, in patients with EGFR-mutant advanced NSCLC, who have been previously treated with a third-generation EGFR-TKI in order to provide data on treatment effect and sample size required for a future phase III trial. In addition, the safety of the treatment combination will be evaluated.
