Study Overview
Brief Summary
The purpose of this study is to see if the investigator can help the immune system to work against myeloma.
This study will see if a vaccine made with altered dendritic cells will make T cells work against tumor cells. The stem cells collected for the transplant will also be used to grow dendritic cells in the lab. The dendritic cells will carry the antigens. These cells then will be injected under the skin. The investigators will do lab studies before and after the vaccination to find out if the vaccine is working.

Inclusion Criteria
- •Symptomatic multiple myeloma, ISS stages I-III, within 12 months of starting therapy.
- •Completion of induction therapy with Very Good Partial Response (VGPR), or better, by International Myeloma Working Group (IMWG) criteria.
- •Deemed eligible for ASCT by standard institutional criteria.
- •Age ≥18 years.
- •Documentation of CT7, MAGE-A3, or WT1 expression in the bone marrow and/or bone marrow aspirate.
Exclusion Criteria
- •Prior autologous or allogeneic SCT.
- •Previous immunization against CT7, MAGE-A3, other cancer-testis antigens, or WT
- •Known immunodeficiency, HIV positivity, hepatitis B, or hepatitis C.
- •History of autoimmune disease (e.g., rheumatoid arthritis, SLE), other than vitiligo, diabetes, or treated thyroiditis, which are allowed.

Outcomes
Primary Outcomes
Number of Participants Evaluated for Vaccine Safety
Time Frame: 1 year
Participants will be evaluated for the safety of the vaccine, monitored and graded according to the Common Terminology Criteria for Adverse Events (CTCAE) v4.0 for toxicity and adverse event reporting to the Food and Drug Administration. Dose limiting toxicity (DLT) is defined as grade 3 or higher toxicity. The only toxicities captured outside of the SAEs reported will be all grade 1-5 toxicites deemed definitely, probably, or possibly related to the vaccine portion of the study.
Secondary Outcomes
- Median Progression Free Survival(Up to 7 years)
