Personalized Neoantigen Peptide-Based Vaccine in Combination With Pembrolizumab for Treatment of Advanced Solid Tumors

Is NCT05269381 recruiting? Yes, currently enrolling (Sep 2026). This Phase 1/2 trial studies multiple treatments including Neoantigen Peptide Vaccine and Pembrolizumab for anatomic stage iii breast cancer ajcc v8.

Phase 1/2RecruitingMayo ClinicNCT05269381Data as of Sep 2026

Treatment: Cyclophosphamide · Neoantigen Peptide Vaccine · Pembrolizumab · SargramostimThis phase I/II trial tests the safety and tolerability of an experimental personalized vaccine when given by itself and with pembrolizumab in treating patients with solid tumor cancers that have spread to other places in the body (advanced). The experimental vaccine is designed target certain proteins (neoantigens) on individuals' tumor cells. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving the personalized neoantigen peptide-based vaccine with pembrolizumab may be safe and effective in treating patients with advanced solid tumors.
