Official Title: A Randomized Pilot Phase II Study of Docetaxel Alone or in Combination With PANVAC(Trademark)-V (Vaccinia) and PANVAC(Trademark)-F (Fowlpox) in Adults With Metastatic Brea
Brief Summary:
This study will test whether giving a combination of a vaccine together with docetaxel is more effective against breast cancer than docetaxel alone. The Food and Drug Administration has approved docetaxel to treat many cancers, including breast cancer. The vaccine consists of three parts: 1) a "priming vaccine" called PANVAC (PAN (all) VAC (vaccine)) trademark [TM]-V, which is made from vaccinia virus; 2) a "boosting vaccine" called PANVAC[TM]-F, made from fowlpox virus; and 3) sargramostim, or granulocyte macrophage colony stimulating factor (GM-CSF), a protein that may help boost the immune system. Human genes are inserted into the vaccinia and fowlpox viruses to cause production of carcinoembryonic antigen (CEA) and mucin 1 (MUC-1)-two proteins that are often produced by cancer cells and can be used as a target for the immune system to attack the cancer. Another type of deoxyribonucleic acid (DNA) is inserted to cause production of other proteins that enhance immune activity.
Patients 18 years of age or older with metastatic breast cancer (disease that has spread beyond the original site) and whose cancer produces CEA or mucin 1 (MUC-1) protein may be eligible for this study. Patients must have antigen type human leukocyte antigen A2 (HLA-A2). They may have received adjuvant docetaxel treatment at least 3 months before entering this study, prior hormonal therapy and up to three chemotherapy regimens. Candidates are screened with a medical history and physical examination, blood and urine tests, electrocardiogram, and computerized tomography (CT) or magnetic resonance imaging scans.
Participants are randomly assigned to one of two treatment groups - docetaxel alone or docetaxel plus vaccine - as follows:
Docetaxel Alone
