A Phase I Trial of Vaccination With CT7, MAGE-A3, and WT1 mRNA-electroporated Autologous Langerhans-type Dendritic Cells as Consolidation for Multiple Myeloma Patients Undergoing Autologous Stem Cell Transplantation
In Brief
A Phase 1 clinical trial evaluating CT7, MAGE-A3, and WT1 mRNA-electroporated Langerhans cells ( LCs) and Standard of care for Multiple Myeloma. Completed, enrolled 28 participants across 1 site.
Detailed 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.

Timeline
Interventions
Patients receive CT7/MAGE-A3/WT1 mRNA-electroporated autologous Langerhans-type dendritic cells ID on days 12, 30, and 90 after autologous stem cell transplant. Patients on the vaccine arm of the study will receive a total of 3 vaccinations, comprising a primary immunization on day +12 after ASCT followed by two boosters at days +30 and +90. Vaccines will be dosed at 9x10\^6 LCs per vaccine x 3.
