Official title

A Randomized, Open-Label, Phase 2 Study of a Patient-Specific Vaccine Targeting Neoantigens in Combination With Immune Checkpoint Blockade for Patients With Colon Cancer With Minimal Residual Disease Following Surgical Resection and Standard Adjuvant Chemotherapy

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The primary objective is to assess and characterize the antitumor activity and safety and tolerability of adjuvant treatment with an individualized neoantigen vaccine called GRT-C901/GRT-R902 (chimpanzee adenovirus \[ChAd\] and self-amplifying messenger RNA \[samRNA\] vectors), in combination with checkpoint inhibitors. Antitumor activity will be based on molecular response in patients with colon cancer who have circulating tumor deoxyribonucleic acid (ctDNA) following surgical resection.
