Trial of PalloV-CC in Colon Cancer

This study is a phase Ib prospective, open label study evaluating the effect of vaccination on the immune microenvironment of cancers with results compared to banked tissue from historical controls. Prospectively vaccinated patients will also serve as their own controls by comparing the immune microenvironment of the tumor in pre-treatment biopsies to post-treatment surgical specimens. This is also a dose-escalation study with consecutive enrollment and advancement of cohorts in an overlapping fashion.
