Vaccine Therapy for HER2+ Stage IV Breast Cancer
Phase II Study to Evaluate the Development of HER2/neu (HER2)-Specific Memory T Cells After HER2 Peptide-Based Vaccination in Patients with Advanced Stage HER2+ Breast Cancer
Status Conditions Phase Study ID
Closed Breast Cancer Phase II 7905

This phase II trial studies how well vaccine therapy works in treating patients with stage IV hormone receptor positive breast cancer. Vaccines made from peptides may help the body build an effective immune response to kill tumor cells.
