Study of an Individualized Vaccine Targeting Neoantigens in Combination With Immune Checkpoint Blockade for Patients With Colon Cancer

NCT05456165

Phase 2 Withdrawn Gritstone bio, Inc.
RandomizedParallel-groupOpen-labelTreatment

Summary

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.
