Excerpt:
Patients with FGFR2b overexpression irrespective of ctDNA gene amplification benefited from bema: IHC+/ctDNA- PFS hazard ratio (HR) 0.63 (95% CI 0.4, 0.99), OS HR 0.66 (95% CI 0.39, 1.12....Pts with overexpression of FGFR2b even without ctDNA amplification demonstrated a benefit from the addition of bema to mFOLFOX6….

Excerpt:
The ORR was 17.9% (95% CI, 6.1% to 36.9%) in patients with GEA with high FGFR2b overexpression...Stable disease was the best observed response in 13 additional patients, leading to an overall DCR (PR plus stable disease) of 64.3% (95% CI, 44.1% to 81.4%) in the subgroup with high FGFR2b overexpression.
