PNV21-001: A Phase I Study of a Personalized Multi-Peptide Neo-Antigen Vaccine in Breast Cancer, Pre-Treated Nonsmall Cell Lung Cancer and PD1/PD-L1 Inhibitor-Refractory Melanoma
Fred Hutchinson Cancer Center
Summary
This phase I trial studies the safety of personalized neo-antigen peptide vaccine in treating patients with stage IIIC-IV melanoma, hormone receptor positive HER2 negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic) or does not respond to treatment (refractory) or stage III-IV non-small cell lung cancer. Personalized neo-antigen peptide vaccine is a product that 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.
Description
OUTLINE: Patients receive poly ICLC intramuscularly (IM) or intratumorally (IT) once weekly in weeks when no vaccine is given. Beginning 2 weeks after starting poly ICLC, patients receive personalized neo-antigen peptide vaccine IM once every 4 weeks and nivolumab intravenously (IV) every 2 or 4 weeks. Treatment continues for 25 weeks in the absence of disease progression or unacceptable toxicity. Patients determined to have clinical benefit on a first course of treatment may repeat a 6-month course of treatment as described above. Patients then receive nivolumab IV every 2 or 4 weeks for up…
