Exploratory Study of TG02-treatment as Monotherapy or in Combination With Pembrolizumab to Assess Safety and Immune Activation in Patients With Locally Advanced Primary and Recurrent Oncogenic RAS Exon 2 Mutant Colorectal Cancer

The purpose of this study is to determine safety and anti-tumor immune activation generated by TG02 and Granulocyte macrophage colony stimulating factor (GM-CSF), first as monotherapy (Part I), thereafter in combination with the checkpoint inhibitor pembrolizumab (Part II), in patients with locally advanced primary and recurrent colorectal cancer scheduled to have surgery.
Part I will include 4-6 patients and Part II will include up to 10 patients. Part I and Part II are separate and independent sequential components of the study. Patients will only be able to participate in either the Part I cohort or Part II cohort.
Main objective of the study is to investigate safety and immune response after TG02-treatment.
