Breast Cancer Clinical Trial
Vaccine Therapy in Treating Patients With HER2-Negative Stage III-IV Breast Cancer
Summary
This phase I trial studies the side effects and best dose of multiantigen deoxyribonucleic acid (DNA) plasmid-based vaccine in treating patients with human epidermal growth factor receptor 2 (HER2)-negative stage III-IV breast cancer. Multiantigen DNA plasmid-based vaccine may target immunogenic proteins expressed in breast cancer stem cells which are the component of breast cancer that is resistant to chemotherapy and has the ability to spread. Vaccines made from DNA may help the body build an effective immune response to kill tumor cells.
Full Description
OUTLINE: This is a dose-escalation study. Patients are assigned to 1 of 4 arms.
Arm 1: Patients receive CD105/Yb-1/SOX2/CDH3/MDM2-polyepitope plasmid DNA vaccine with recombinant human granulocyte-macrophage colony-stimulating factor (rhuGM-CSF) as 1 injection intradermally (ID) every 28 days for 3 months. Patients may also receive 2 additional booster STEMVAC vaccines at 3 and 9 months after the third vaccine in the absence of unacceptable toxicity or disease progression.
ARM 2: Patients receive CD105/Yb-1/SOX2/CDH3/M2-polyepitope plasmid DNA vaccine with rhuGM-CSF as 2 injections ID every 28 days for 3 months. Patients may also receive 2 additional booster STEMVAC vaccines at 3 and 9 months after the third vaccine in the absence of unacceptable toxicity or disease progression.
ARM 3: Patients receive CD105/Yb-1/SOX2/CDH3/MDM2-polyepitope plasmid DNA vaccine with rhuGM-CSF as 3 injections ID every 28 days for 3 months. Patients may also receive 2 additional booster STEMVAC vaccines at 3 and 9 months after the third vaccine in the absence of unacceptable toxicity or disease progression.
ARM 4: Patients receive CD105/Yb-1/SOX2/CDH3/MDM2-polyepitope plasmid DNA vaccine with rhuGM-CSF as 2 injections ID every 28 days for 3 months. Patients may also receive 1 additional STEMVAC vaccine at 3 months after the third vaccine in the absence of unacceptable toxicity or disease progression.
After completion of study treatment, patients are followed up twice yearly for up to 5 years.
