In brief

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.

LVEF may be established with echocardiogram or MUGA scan, and left ejection fraction must be >= 50%. Cardiac evaluation for other patients is at the discretion of the treating physician
• Subjects with a history of myocarditis or congestive heart failure (as defined by New York Heart Association functional classification III or IV), as well as unstable angina, serious uncontrolled cardiac arrhythmia, uncontrolled infection, or myocardial infarction 6 months prior to study entry will be excluded

• Drug exposure >= 6 weeks and best response progressive disease (PD) or stable disease (SD) < 6 months or
• Drug exposure >= 6 months and best response complete response (CR), partial response (PR), or SD > 6 months
• MELANOMA SPECIFIC: A confirmatory scan performed at least 4 weeks after disease persistence/progression is required but this requirement can be waived if the judgement of the treating clinician is that the patient would be at risk of rapid or symptomatic progression in that interval. This confirmatory scan can occur during production of the vaccine after enrollment
