Long-term Idiotype Vaccination Combined with Interleukin-12 (IL-12), or IL-12 and Granulocyte Macrophage Colony-Stimulating Factor, in Early-Stage Multiple Myeloma Patients

Abstract

These results indicate that idiotype immunization of myeloma patients with GM-CSF and IL-12 may induce specific T-cell response more frequently than with IL-12 alone and that immune response may correlate with time to progression and nonresponse with increased numbers of regulatory T cells.
