Vaccination With Dendritic Cell/Tumor Fusions With Autologous Stem Cell Transplants in Patients With Multiple Myeloma

The main purpose of this study is to test the safety and determine the type and severity of any side effects of the Dendritic Cell Fusion Vaccine given in combination with an autologous transplant for patients with multiple myeloma. Autologous stem cell transplantation is a standard therapy for multiple myeloma that is often successful in significantly decreasing the amount of cancer. However, it is not a cure because at some point the multiple myeloma generally begins to grow again. Cancer vaccines are investigational agents that try to stimulate the immune system to recognize and fight against cancer cells. One type of cancer vaccine uses an immune stimulating cell of the body known as a dendritic cell. Research has shown that these dendritic cells can stimulate an immune response against the tumor.
