What This Study Found

The PGV001 personalized neoantigen vaccine platform was feasible, safe, and triggered immune responses in patients with solid and blood cancers. It predicted immunogenic targets even in tumors with few mutations.

Key Numbers

Phase 1 study in solid and hematologic malignancies. OpenVax pipeline predicted neoantigens across wide-ranging mutational burdens. Three additional trials launched (glioblastoma, urothelial cancer + ICI, prostate cancer).

How They Did This

Phase 1, open-label study of the PGV001 personalized multi-peptide neoantigen vaccine in patients with solid and hematologic cancers in the adjuvant setting. Used OpenVax computational pipeline for neoantigen prediction.

Why This Research Matters

Personalized cancer vaccines are a frontier of immunotherapy. This Phase 1 trial shows the approach works safely across tumor types and has spawned three follow-up trials in glioblastoma, bladder cancer, and prostate cancer.

What This Study Doesn't Tell Us

Phase 1 (safety/feasibility focus). Small sample size typical of Phase 1. No efficacy endpoints. Adjuvant setting only.
