In vivo antitumor activity of AZD6422 in PDX models of gastric cancer, PDAC, and esophageal adenocarcinoma. Activity and tolerability of AZD6422 are shown in various PDX models of esophageal adenocarcinoma (A, ES11085; D, ES_9500), gastric cancer (E, GA_9275), and PDAC (B, PANC_22; C, PANC_12; F, PANC_24). Each model was selected to represent a range of CLDN18.2 (shown at 10× scan) and TGFβ expression. NSG MHC-DKO mice received a single tail-vein infusion of 1e6 AZD6422, donor-matched UT, or vehicle when the average tumor volume reached 150 mm³. Tumor volumes and body weights were measured biweekly until study completion on day 35, and blood was collected for cytokine analysis on days 7 and 14. Data are shown as mean ± SEM (n = 5).
