"We are encouraged by the early evidence of responses in patients with cold tumors, including MSS colorectal cancer, reported for the combination of vilastobart and atezolizumab in Phase 1C dose escalation earlier this year, and we look forward to sharing initial Phase 2 data for the combination in MSS CRC at ASCO GI in January," said Katarina Luptakova, M.D., chief medical officer of Xilio.

"In addition, the preliminary Phase 1 data we reported today for XTX301, our tumor-activated IL-12, highlight its promising clinical profile, including no dose-limiting toxicities reported to date and consistent interferon gamma signaling observed throughout treatment cycles."
