Summary
This phase I trial studies the safety of personalized neo-antigen peptide vaccine in treating patients with stage IIIC-IV melanoma or hormone receptor positive Her2 negative breast cancer that has spread to other places in the body (metastatic) or does not respond to treatment (refractory). Personalized neo-antigen peptide vaccine is a product combines multiple patient specific neo-antigens. Given personalized neo-antigen peptide vaccine together with Th1 polarizing adjuvant poly ICLC may induce a polyclonal, poly-epitope, cytolytic T cell immunity against the patient's tumor.
