In the treatment of locally advanced or metastatic biliary tract cancers
Prespecified exploratory analysis of mutation status in the TOPAZ-1 study
- At the prespecified interim OS analysis (data cutoff: August 11, 2021), IMFINZI + gem-cis significantly improved OS vs gem-cis (HR=0.80 [95% CI, 0.66-0.97]; P=0.021)1
- The prevalence of genomic alterations and associated outcomes in the BEP were assessed in TOPAZ-1. This exploratory analysis was conducted and descriptively assessed with 6.5 months of additional follow-up (data cutoff: February 25, 2022)2
