Tumor Cell Vaccines and ISCOMATRIX With Chemotherapy After Tumor Removal

Stopped early · Phase 1

Conditions studied: Sarcoma, Melanoma, Epithelial Malignancies, Pleural Malignancy

In brief

Background: \- A tumor cell vaccine is an experimental cancer treatment. Cancer cells are collected from a patient and then used to develop a vaccine. The vaccine will produce an immune system response to help destroy other cancer cells in the body. Researchers are studying ways to improve these tumor cell vaccines. One way is to add an adjuvant. An adjuvant is a substance that brings about a stronger immune system response. ISCOMATRIX is an adjuvant that has been used safely in other clinical studies. But it has not been studied with certain tumor cell vaccines. Researchers want to find out whether a tumor cell vaccine with ISCOMATRIX, given along with cancer drug treatment, is a safe and effective way to slow or prevent tumor growth after tumor removal surgery. Objectives: \- To assess the safety and effectiveness of tumor cell vaccines given with ISCOMATRIX and drug therapy after tumor removal surgery. Eligibility: \- People at least 18 years of age who have had tumor cell vaccines developed from cells taken from surgically removed tumors. Design: * Patients will be screened with a physical examination, medical history, blood and urine tests, and imaging studies. * Patients will be treated with cyclophosphamide (once daily) and celecoxib (twice daily) for 7 days before the first vaccine dose. * Patients will receive the tumor cell vaccine once a month for 6 months. They will continue to receive drug therapy throughout the vaccine treatment. Patients will be monitored with regular blood tests and imaging studies. * After the first 6 months, patients who have an immune response to the vaccine will continue treatment with the vaccine and chemotherapy. They will also have regular blood tests and imaging studies. They will have this treatment for up to 24 months from the first vaccination or until they no longer have an immune response. * Participants will have followup visits for up to 5 years after the first vaccination, or until the tumor returns.

You may not qualify if…

• Patients requiring corticosteroids (other than inhaled) will be excluded.
• Patients with life expectancy less than 12 months will be excluded.
• Patients receiving warfarin anticoagulation, who cannot be transferred to other agents such as enoxaparin or dabigatran, and for whom anticoagulants cannot be held for up to 24 hours will be excluded.
• Patients with uncontrolled hypertension (>160/95), unstable coronary disease evidenced by uncontrolled arrhythmias, unstable angina,decompensated CHF (>NYHA Class II), or myocardial infarctionwithin 6 months of study will be excluded.
• Patients with other cardiac diseases may be excluded at the discretion of the PI following consultation with Cardiology consultants.
• Patients with any of the following pulmonary function abnormalities will be excluded: FEV, < 30% predicted; DLCO < 30% predicted (post-bronchodilator); pO2 < 60% or pCO2 (Bullet) 50 on room air arterial blood gas.
• Pregnant and/or lactating women will be excluded due to the unknown, potentially harmful effects of immune response to CT-X antigens and stem cell proteins that may be expressed in placenta, fetus, and neonates.
• Patients with active infections, including HIV, will be excluded, due to unknown effects of the vaccine on lymphoid precursors.
