The trial included 25 people with pancreatic or colorectal cancer who had previously undergone surgery, seven of whom also had received radiation therapy. They were given up to 10 doses of the vaccine known as ELI-002, and the results were promising: 84 percent of all participants had positive T cell responses—and all of those who received higher doses had a response. The results of the trial, which was funded by Boston-based biotech company Elicio Therapeutics, were published in Nature Medicine.
