This phase I trial studies the side effects and best dose of personalized synthetic long peptide vaccine therapy in treating patients with triple-negative breast cancer. A peptide is a naturally occurring biological molecule made up of amino acids. The personalized synthetic long peptide vaccine is designed to target mutations (any change in the deoxyribonucleic acid [DNA] sequence of a cell) specific to each person’s tumor that are discovered during genetic testing of the tumor before study procedures start. Injection of this vaccine may be a way to generate an immune response to breast cancer cells.
Study sponsor and potential other locations can be found on ClinicalTrials.gov for NCT02427581.
PRIMARY OBJECTIVES:
I. To evaluate the safety of the personalized synthetic long peptide breast cancer vaccine strategy.
SECONDARY OBJECTIVES:
I. To evaluate the immunogenicity of the personalized synthetic long peptide breast cancer vaccine strategy.
EXPLORATORY OBJECTIVES:
I. To evaluate the immunogenicity, and clinical response that may be associated with immune responses induced by the personalized synthetic long peptide breast cancer vaccine strategy.
OUTLINE:
Patients receive personalized synthetic long peptide breast cancer vaccine subcutaneously (SC) on days 1, 4, 8, 15, 22, 50, and 78 in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 52 weeks and then annually thereafter.
