$CADL The poster is Abstract 603 from SITC today (Nov 6) in Phoenix: Stanford and Candel’s multi-omics look at the phase 2 LuTK02 lung trial. It is not new survival data from a controlled study. It asks whether CAN-2409 (aglatimagene plus valacyclovir) actually turns the immune system on in people whose non-small cell lung cancer had already stopped responding to checkpoint inhibitors, and whether that activation lines up with living longer.
In plain terms, it supports the “cold to hot” idea in lung cancer. After the injections, two things showed up together: killer immune activity rose inside the tumor, and the same kind of activity showed up in the blood, meaning the effect was not limited to the injected site. The T-cell repertoire also got more diverse, which means new T-cell clones appeared. That is the in situ vaccine pattern you’ve been asking about: the tumor itself supplies the antigens, and the immune system starts recognizing more of them.
