KRAS-Targeted Vaccine Shows Robust Immune Response, Longer-Than-Expected Survival in Pancreatic and Colorectal Cancer Trial

Researchers plan larger studies of a multivalent version to confirm benefit.

Overview

  • In a UCLA-led phase 1 study of 25 post‑surgery patients, 21 generated KRAS‑specific T cells after receiving the ELI‑002 2P vaccine.
  • Median relapse‑free survival reached about 16 months and overall survival about 28 months, surpassing historical expectations for these cancers.
  • Patients with the strongest KRAS‑specific responses saw the greatest benefit, and 67% also mounted responses to additional tumor‑associated mutations.
  • KRAS mutations drive roughly half of colorectal cancers and more than 90% of pancreatic cancers, providing a clear rationale for this targeted approach.
  • Investigators are advancing a broader candidate, ELI‑002 7P, with larger follow‑up trials planned to evaluate whether the immune signals translate into clinical benefit.
