Dendritic Cell DKK1 Vaccine for Monoclonal Gammopathy and Stable or Smoldering Myeloma

The purpose of this study is to study the safety and preliminary efficacy of a dendritic cell DKK1 vaccine against myeloma. Dendritic cells are immune cells that are collected from the blood of the patient at Case Western Reserve Medical Center and then brought into contact with DKK1, a molecule that is present of myeloma cells but not to a significant amount on other cells except for the prostate and the placenta. It is an investigational (experimental) vaccine that based on studies in the laboratory and in mice is expected to work by presentation of DKK1 to anticancer immune cells via dendritic cells leading to an immune attack on myeloma cells. It is experimental because it is not approved by the Food and Drug Administration (FDA).
