Precision DC: Personalized Neoantigen Dendritic Cell Vaccine Pilot Trial for High Risk Triple Negative Breast Cancer After Neoadjuvant Therapy
H. Lee Moffitt Cancer Center and Research Institute
Summary
This is a pilot protocol to evaluate the safety, feasibility, and immunogenicity of a personalized breast cancer vaccine based utilizing whole exome sequencing data of a patient's residual breast tumor following neoadjuvant chemotherapy.

Inclusion Criteria: * Patient has stage II-III ER/PR less than or equal to 10% HER2 negative by FISH and/or IHC breast cancer treated with standard of care neoadjuvant systemic chemotherapy and surgical resection with significant residual breast tumor (equivalent to RCB II or III) disease. * Patient has sufficient residual viable primary breast tumor or ipsilateral breast axillary nodal metastatic cancer tissue accessible to Moffitt for whole exome sequencing. * Patient is 18 years of age or older. * Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 * Patients must have adeq…
Interventions
- ProcedureLeukapheresis
Removal of white blood cells (leukocytes) from the blood. The dendritic cells are harvested from the white blood cells that are collected and trained to recognize the specific abnormal proteins found in the tumor sample. One needle is inserted in each arm. An apheresis machine removes blood from the vein in one arm, separates and retains the leukocytes from the blood, and then returns the rest of the blood to the other arm.
- BiologicalDendritic Cell (DC) Vaccine
The vaccine will be given intranodally (inguinal or axillary) under ultrasound guidance using a dose of 40-50 million cells three times spaced 2 weeks apart for the initial priming sequence. 3 doses of the priming vaccines are given once every 2 weeks. 2 booster shots (if available) will be given 6 months and 12 months following completion of initial priming vaccines.
