Vaccine Treatment for Advanced Breast Cancer

Stopped early · Phase 1/Phase 2

Conditions studied: Breast Cancer

In brief

This 2-phase study will determine the safety of treating patients with breast cancer with the genetically engineered HyperAcute-Breast cancer vaccine. It will establish the proper vaccine dose and will examine side effects and potential benefits of the treatment. The vaccine contains killed breast cancer cells containing a mouse gene that causes the production of a foreign pattern of protein-sugars on the cell surface. It is hoped that the immune response to the foreign substance will stimulate the immune system to attack the patient's own cancer cells that have similar proteins without this sugar pattern, causing the tumor to remain stable or shrink. Patients 18 years of age or older with breast cancer that has recurred or no longer responds to standard treatment may be eligible for this study. Candidates will be screened with medical history and physical examination, blood tests, urinalysis, chest x-rays and CT scans. MRI, PET, and ultrasound scans may be obtained if needed. Participants will receive four vaccinations a month apart from each other. The vaccines will be injected under the skin, similar to the way a tuberculosis skin test is given. Phase I of the study will treat successive groups of patients with increasing numbers of the vaccine cells to evaluate side effects of the treatment and determine the optimum dose. Phase II will look for any beneficial effects of the vaccine given at the highest dose found to be safe in Phase I. Weekly blood samples will be drawn during the 4 months of vaccine treatment. In addition, patient follow-up visits will be scheduled every 2 months for the first year after vaccination and then every 3 months for the next 2 years for the following tests and procedures to evaluate treatment response and side effects: * Medical history and physical examination * Blood tests * X-rays and various scans (nuclear medicine/CT/MRI) * FACT-B Assessment questionnaire to measure the impact of treatment on the patient's general well-being. The questionnaire is administered before beginning treatment, before each vaccination, and during follow-up visits after completing the treatment. It includes questions on the severity of breast cancer symptoms and the ability to perform normal activities of daily life.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Histological diagnosis of infiltrating breast carcinoma, including infiltrating ductal carcinoma, lobular carcinoma, medullary carcinoma, colloid, comedocarcinoma, papillary, inflammatory carcinoma, signet ring carcinoma. The patient's pathology must be reviewed and confirmed by Iowa Methodist Medical Center's or Mercy Medical Center's Pathology Department.
• AJCC Stage IV (any T, any N, M1), metastatic, progressive or recurrent breast carcinoma. Patients may not be eligible for other curative intent treatment (e.g. surgical resection). Patients must have failed one salvage treatment.
• Eastern Cooperate Oncology Group Performance Status less than or equal to 2.
• Serum albumin greater than or equal to 3.0 gm/dL.
• Expected survival greater than or equal to 6 months.
• Subjects must have a negative serology for Hep B, C and HIV prior to entering study.
• Adequate organ function including: Marrow: Hemoglobin greater than or equal to 10.0 mg/dL, absolute granulocyte count (AGC) greater than or equal to 1,500/mm(3), platelets greater than or equal to 100,000/mm(3), absolute lymphocyte count greater than or equal to 475/mm(3). Hepatic: serum total bilirubin less than or equal to 1.5 x upper limit of normal (ULN), ALT (SGPT) and AST (SGOT) less than or equal to 2.5 x ULN. Renal: serum creatinine less than or equal to 1.5 x ULN or creatinine clearance greater than or equal to 50 mL/min.
• All on-study tests must be less than or equal to Grade I toxicity for patient to be eligible for study, excluding serum LDH levels. PT, PTT must be less than or equal to 1.5 x ULN except for patients who are on therapeutic anticoagulant therapy.
• Measurable or non-measurable disease as defined as:
• Measurable - those that can be accurately measured in at least one dimension (longest diameter to be recorded) as greater than or equal to 20 mm with conventional techniques (CT, MRI, x-ray) or as greater than or equal to 10 mm with spiral CT scan. All tumor measurements must be recorded in millimeters (or decimal fractions of centimeters).
• Non-measurable - All other lesions (or sites of disease), including small lesions (longest diameter less than 20 mm with conventional techniques or less than 10 mm using spiral CT scan), are considered non-measurable disease. Bone lesions, leptomeningeal disease, ascites, pleural or pericardial effusions, lymphangitis cutis or pulmonis, inflammatory breast disease, abdominal masses (not followed by CT or MRI), and cystic lesions are all considered non-measurable.
• Prior therapy for breast cancer that may include surgery, radiation therapy, and/or less than or equal to 2 different cytotoxic chemotherapy regimens (including neoadjuvant and adjuvant treatment). Patients receiving preoperative (neoadjuvant) and postoperative (within 12 weeks of surgery) adjuvant chemotherapy with the same agent(s) will be considered to have received a single chemotherapy regimen.
• Patients with previously treated, unresponsive or progressive disease that have failed at least one salvage regimen.
• Patients must be greater than or equal to 4 weeks since major surgery, radiotherapy, chemotherapy (6-weeks if they were treated with a nitrosourea or mitomycin) and recovered from the toxicity of prior treatment to less than or equal to Grade 1, exclusive of alopecia or fatigue.
• Patients must have the ability to understand the study, its risks, side effects, potential benefits and is able to give written informed consent to participate. Patients may not be consented by a durable power of attorney (DPA).
• Male and female subjects of child producing potential must agree to use contraception or avoidance of pregnancy measures while enrolled on study and receiving the experimental drug, and for one month after the last immunization.

You may not qualify if…

• Age less than 18-years-old.
• Active CNS metastases or carcinomatous meningitis.

Patient's curatively treated for squamous and basal cell carcinoma of the skin and carcinoma in situ of the uterine cervix (CIN) or patients with a history of malignant tumor in the past that have been disease free for at least five years are also eligible for this study.
• History of organ transplant or current active immunosuppressive therapy (such as cyclosporine, tacrolimus, etc.) or history of prior immunotherapy except Herceptin and/or other monoclonal antibody therapies.
• Subjects taking systemic corticosteroid therapy for any reason including replacement therapy for hypoadrenalism, are not eligible. Subjects receiving inhaled or topical corticosteroids are eligible. Subjects who require systemic corticosteroids after beginning vaccinations, will be removed from the study.
