Brief Summary

One purpose of this study is to find out if a new combination of immune system treatments (MAGE-A3 vaccine plus activated T-cells) will allow the body to build up protection ("immunity") against the myeloma cells. A second purpose is to find out how well this combination of immune system treatments is able to control the myeloma.

Detailed Description

Autologous stem cell transplant (ASCT) can lead to a complete or partial disappearance of the myeloma in about 2 out of 3 patients. However, an ASCT only sometimes leads to a cure of the myeloma. In about half the patients the myeloma comes back after about 1-2 years. In about 90% of patients it comes back by about 10 years after transplant.

One possible way to improve upon the results of ASCT for myeloma is to help the body's defense or immune system recover faster after transplant. Another way is to teach the body's immune system to fight against the myeloma cells.

In two earlier research studies which included more than 100 patients, certain types of immune cells called "T cells" or "T lymphocytes" were taken out of a patient's body using a procedure called "apheresis". These cells were then grown up in the lab. After the transplant, these T cells were put back into the patients. The replaced T cells helped the patients'immune systems to recover faster after the transplant. In addition, when the T cells were given back to patients they also received a vaccination. The vaccination or injection was for a certain type of pneumonia germ called "pneumococcus". We found that most patients built up protection against this pneumonia-causing germ. In another study, we used a possible myeloma cancer vaccine. However, we found that less than half the patients responded to this vaccine.

In this new study, we want to test a different type of myeloma cancer vaccine. This different cancer vaccine is based on a protein called MAGE-A3. The MAGE-A3 protein is found in about 50% of cases of myeloma. This vaccine consists of small pieces of protein (called "peptides") which come from the MAGE-A3 protein. In order to help the immune system respond better we will add two new steps. First we will add an immune system stimulant called "Hiltonol®" to each vaccination. Hiltonol® is a chemical substance that turns on several parts of the immune system. It may make the immune system better able to respond to the vaccine. It has been tested in several hundred patients and has been used with about a dozen different types of cancer and germ vaccines. Second, starting about 100 days after the transplant procedure, patients will get a medicine called Lenalidomide. Lenalidomide is already approved by the Food and Drug Administration (FDA) for treatment of myeloma. In this study, we want to know whether Lenalidomide could help to improve the body's ability to respond to the vaccinations and help to treat the myeloma itself.

Group	Intervention	Description
Prevnar, T Cells, Lenalidomide, MAGE A-3	Activated/costimulated autologous T-cell	All patients will receive a priming immunization with a MAGE-A3/GM-CSF vaccine with adjuvant Hiltonol® (Poly-ICLC) along with the pneumococcal conjugate vaccine/PCV control vaccine about 10 days before a steady-state mononuclear cell apheresis. Patients will then undergo hematopoietic stem cell mobilization. All patients will receive high-dose melphalan followed by hematopoietic stem cells on day 0.
