Design outcomes

Primary

MeasureTime frameDescription
Progression-free survival (PFS) for bevacizumab plus first-generation EGFR-TKIs by investigator using RECIST v1.1This is a real-world study. The estimated median PFS for bevacizumab plus first-generation EGFR-TKIs is 18 months according to previous data.To evaluate the efficacy of bevacizumab combined with first-generation EGFR-TKIs in patients with EGFR-mutant NSCLC as measured by investigators
Progression-free survival (PFS) for bevacizumab plus second-generation EGFR-TKIs by investigator using RECIST v1.1This is a real-world study. The estimated median PFS for bevacizumab plus second-generation EGFR-TKIs is 20 months according to previous data.To evaluate the efficacy of bevacizumab combined with second-generation EGFR-TKIs in patients with EGFR-mutant NSCLC as measured by investigators.
Progression-free survival (PFS) for bevacizumab plus third-generation EGFR-TKIs by investigator using RECIST v1.1This is a real-world study. The estimated median PFS for bevacizumab plus third-generation EGFR-TKIs is 22 months according to previous data.To evaluate the efficacy of bevacizumab combined with third-generation EGFR-TKIs in patients with EGFR-mutant NSCLC as measured by investigators.

Secondary

MeasureTime frameDescription
Objective response rate (ORR) by investigator using RECIST v1.1Baseline overall tumor assessment can be performed up to 28 days after the first-dose of treatment. Post-baseline assessment will be performed every six weeks until 1st disease progression, through study completion, an average of 2 years.To evaluate the efficacy of bevacizumab combined with EGFR-TKIs in patients with NSCLC harbouring activating EGFR mutations, with or without EGFR T790M mutation,as measured by investigators assessed objective response rate using RECIST v1.1
Incidence of Treatment-Emergent Adverse Events using CTCAE V5.0This is a real-world study. Safety of the combination treatment is expected to perform until the study completion, an average of 1.5 years,according to CTCAE V5.0.To evaluate the incidence of Treatment-Emergent Adverse Events of bevacizumab combined with EGFR-TKIs in patients with NSCLC harbouring activating EGFR mutations,with or without EGFR T790M mutation.
Disease control rate (DCR) by investigator using RECIST v1.1Baseline overall tumor assessment can be performed up to 28 days after the first-dose of treatment. Post-baseline assessment will be performed every six weeks until 1st disease progression, through study completion, an average of 2 years.Disease control rate (DCR) will be analyzed using similar method as objective response rate.
Overall survivalThe primary analysis on overall survival is espected to perform on 48 months of follow-up.To evaluate the efficacy of bevacizumab combined with EGFR-TKIs in patients with NSCLC harbouring activating EGFR mutations,with or without EGFR T790M mutation,as measured by investigators assessed overall survival.
