TPS9120 Background: Vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) pathways are shown to be interrelated in several preclinical studies. Furthermore, recent clinical studies have shown the adding effect of an anti VEGF monoclonal antibody with an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) for the non-small-cell lung cancer (NSCLC) patients with EGFR mutation. Thus, osimertinib plus ramucirumab would be the promising candidate for the new standard treatment in EGFR mutation positive NSCLC. Methods: This study is an investigator initiated trial. Previously untreated EGFR mutation positive advanced non squamous NSCLC patients aged 20 years or older with a performance status of 0 or 1 are randomized at a 1:1 ratio to receive osimertinib (80mg) every day either without or with ramucirumab (10mg/kg) every 2 weeks until evidence of disease progression or development of unacceptable toxicity. The primary endpoint of the study is progression free survival (PFS) assessed by the central image reviewer. Secondly endpoints include PFS (assessed by an attending physician), objective response rate (ORR), disease control rate (DCR), duration of response (DOR), overall survival (OS), safety and toxicity profile. Stratification factors are gender and the type of EGFR mutation (exon 19 deletion, Leu858Arg point mutation in exon 21). We determined that, with a sample size of 120 patients (60 in each arm), the trial will have 80% power to show a hazard ratio for disease progression or death of 0.667 at a one-sided alpha level of 0.2 (as calculated on the basis of 80 such events) for comparison between the two arms with 1.5-year accrual and 2-year follow-up periods. Study enrollment began in November 2018 and is continued for 3.5 years among 20 sites of Thoracic Oncology Research Group (TORG). Seven patients were enrolled at time of submission. Clinical trial information: 184146.
