Study Design
Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment
Name: CT7, MAGE-A3, and WT1 mRNA-electroporated Langerhans cells ( LCs) Type: Biological
Name: Standard of care Type: Other
Overall Status
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.
Criteria for eligibility
Healthy Volunteers: No
Maximum Age: N/A
Minimum Age: 18 Years
Gender: Both
Criteria: 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 WT1.

- 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.

- History of severe allergic reactions to vaccines or unknown allergens.

- Participation in any other clinical trial involving another investigational agent within 4 weeks prior to first immunization.

- Lenalidomide-related toxicities before ASCT necessitating its discontinuation as part of treatment.
