PolyPEPI1018 Vaccine and CDx for the Treatment of Metastatic Colorectal Cancer (OBERTO)

Phase I/II clinical trial investigates the safety, tolerability, immunogenicity and preliminary efficacy of multiple doses of PolyPEPI1018 CRC vaccine as an add-on treatment to the standard-of-care maintenance therapy in patients with metastatic colorectal cancer. Clinical responses will be evaluated by indiction of T cell responses, T lymphocyte infiltration in accessible biopsy sites, and by objective tumor responses. This study will also explore the accuracy of the predicted T cell responses in each patient using the candidate companion diagnostic test and the correlations between clinical responses and predicted T cell responses.
