Vaccine and Chemotherapy for Previously Untreated Metastatic Breast Cancer



Vaccine and Chemotherapy for Previously Untreated Metastatic Breast Cancer

For Condition: Metastases, Neoplasm,Breast Neoplasms
Status: Recruiting
Sponsor(s): National Cancer Institute (NCI) ,
Synopsis: This study will evaluate the safety and effectiveness of a combination of vaccines and chemotherapy to treat metastatic breast cancer (breast cancer that has spread beyond the breast) in patients whose cancer cells have a surface protein called CEA. Patients who require surgery or radiation therapy, or both, will receive these treatments as well. Patients 18 years of age and older with previously untreated metastatic breast cancer may be eligible for this study. Patients known or found to have metastases in the brain are not eligible for the study. Patients may be newly diagnosed with metastatic breast cancer or known to have breast cancer but newly diagnosed with metastatic disease. Newly diagnosed patients may not have received prior chemotherapy but they may have received hormonal therapy for stage IV disease. Patients previously diagnosed with local disease may have received chemotherapy or radiation therapy but at least 18 months before entering the current study. Candidates will be screened with blood and urine tests, x-rays, and heart and lung tests. Participants undergo the following procedures: 1. Central venous line: Under local or general anesthesia, an intravenous catheter (plastic tube) is inserted into a major vein in the chest. It is used to give chemotherapy and other medications and to withdraw blood samples. 2. Apheresis: Before beginning chemotherapy, patients undergo apheresis to collect white blood cells (lymphocytes) for later re-infusion at the time of immunizations. For this procedure, blood is collected through the central venous catheter and circulated through a machine that separates the white cells from the rest of the blood. The rest of the blood is returned to the patient through the catheter. The white cells are removed and frozen for later use. 3. First vaccine: Before starting chemotherapy, patients receive one subcutaneous (under the skin) injection of a vaccine called rV-CEA-Tricom, along with subcutaneous injections of GM-CSF (Sargramostim), a drug that stimulates the response of the immune system to the vaccine. 4. Chemotherapy. Chemotherapy includes: -Taxol (paclitaxel)/Cytoxan (cyclophosphamide) - Patients receive three to five cycles of Taxol and Cytoxan. Taxol is given as a continuous 72-hour intravenous (through a vein) infusion and Cytoxan is given daily for 3 days intravenously (IV). Cycles are 21 to 42 (usually 28) days. After each cycle, patients also receive G-CSF (a drug that helps boost white cell counts) by injection under the skin. The also receive Mesna, a drug that protects the bladder from harmful side effects of Cytoxan. -Adriamycin (doxorubicin)/Cytoxan: Patients may receive additional chemotherapy with Adriamycin and Cytoxan for a maximum of 4 cycles. Adriamycin is given as a 10-minute IV bolus and Cytoxan is infused IV over 1 hour. Cycles are usually 21 days. -Immune-depleting chemotherapy: Patients receive a final course of chemotherapy (following radiation, if needed) with Cytoxan and fludarabine to lower the immune system in preparation for receiving the white blood cells (lymphocytes) collected before the start of chemotherapy. -Additional vaccines: Starting 3 weeks after immune-depleting chemotherapy, patients receive a series of immunizations once a month with a second type vaccine called rF-EA-Tricom). Starting 10 months after the immune-depleting chemotherapy, they will get a booster shot of the same vaccine every 6 months for four doses, along with four daily injections of Sargramostim. Along with the first series of immunizations, patients receive the white cells (lymphocytes) that were collected during apheresis to boost the body's response to the vaccines. 5. Hormonal treatment: Patients whose tumors are hormone receptor positive will receive hormonal therapy after all chemotherapies are completed. The total length of treatment varies from about 25 to 41 months, depending on the number of cycles patients receive and whether or not they also undergo surgery or radiation therapy. (The last 18 months consist only of one vaccine injection every 6 months)
Details: Metastatic breast cancer remains to this day a mostly incurable disease, with less than 10% of patients reaching a long-term disease free survival. Unfortunately, the more recently introduced strategy of high-dose chemotherapy and autologous transplantation is unlikely to achieve a high cure rate by itself. This study proposes to treat patients with previously untreated metastatic breast cancer using an immune-depleting chemotherapy as a platform for immunotherapy. It is based on the following hypotheses and understanding: The combination of dose-intensive followed by immune-depleting chemotherapy provides a platform for subsequent immunotherapy by: Lengthening the progression-free survival period, thus allowing time for a slow acting therapy such as vaccination to be effective. Maximally decreasing the patient's tumor burden. This has been shown both in clinical and experimental settings to be desirable if not necessary for immunotherapy to be effective. Decreasing the tumor burden which may also decrease a tumor-induced immunosuppressive effect linked to tumor bulk. Providing tumor antigen exposure following immune depletion in the form of repeated immunizations. This may take advantage of the pattern of immune reconstitution following immune depleting therapy at early time points (antigen-driven peripheral expansion of T-cells) and the renewal of a T-cell repertoire biased towards tumor antigens and anti-tumor responses at later time points. Low antigenicity of tumor antigens and immune tolerance may be overcome in a clinically relevant fashion by providing exposure to the tumor antigen (in our case, the carcino-embryonic antigen CEA) in a more immunogenic presentation along with added co-stimulatory signal (in the form of two poxvirus-based recombinant vaccines). Due to the post immune depletion defects and delay in immune reconstitution, an adequate immune response to vaccines may not occur unless the patients are provided, following immune depletion, with unaltered T-cells in the form of re-infusion of pre-chemotherapy lymphocytes. The late recovery of thymic function (18-24 months) with reappearance of naive T-cells may play a determinant role in the prevention of later disease progression. It is the rationale for a late series of immunizations. Patients will receive conventional induction therapy with Paclitaxel, Cyclophosphamide and Doxorubicin, surgery and/or radiation as indicated for local control, then immune depleting chemotherapy with Fludarabine and Cyclophosphamide. Before any chemotherapy is started, patients will be immunized with one of two tumor-specific, recombinant, poxvirus-based DNA vaccines (rV-CEA(6D)/TRICOM) and lymphocytes will be cryopreserved. Following immune depletion, patients will receive four series of immunization boosts (rF-CEA(6D)/TRICOM) over the next 28 months. The primary objectives are to evaluate biologically this immunization strategy by assessing CEA-specific T-cell responses as well as clinically by comparing the patient EFS to our historical control (protocol 96-C-0104) in which patients have received the same conventional and high-dose therapy but no immunizations.
