BELIEF phase II trial

Patients with EGFR Mut+ NSCLC and pre-existing T790M mutations who received first-line treatment with erlotinib plus bevacizumab, had significantly longer PFS than those patients who were T790M-negative.1

Study design and endpoints1
  • BELIEF was a randomised, single-arm phase II trial that took place across 29 centres in eight European countries.
  • The trial was a proof-of-concept study investigating erlotinib plus bevacizumab as first-line treatment for patients with
    EGFR Mut+ NSCLC, stratified by the presence or absence of the pre-treatment T790M mutation.
