Nivolumab With Epstein Barr Virus Specific T Cells (EBVSTS) Relapsed/Refractory EBV Positive Lymphoma (PREVALE)


Brief description of study

Subjects have a type of a lymph node cancer called Non-Hodgkin's Lymphoma (NHL) or lymphoproliferative disease (LPD), which affects their immunity, blood production, and can involve multiple other organs in the body. Their disease has come back or has not gone away after treatment. The experimental treatment plan consists of an antibody therapy called "Nivolumab" that helps the subjects' T-cells control the tumor, and special immune system cells called EBV-specific cytotoxic T lymphocytes, also a new therapy whose side effects are well studied.

Some patients with NHL or LPD are infected with the virus that causes infectious mononucleosis (called Epstein-Barr virus, or EBV) before or at the time of their diagnosis. The cancer cells that are infected by EBV are able to hide from the body's immune system and escape destruction. Investigators want to see if special white blood cells, called T cells, that have been trained to kill cells infected by EBV can survive in the blood and affect the tumor.

Investigators have used this sort of therapy to treat a different type of cancer that occurs after bone marrow or solid organ transplant called post-transplant lymphoma with good success. These cells are called EBV-specific cytotoxic T-lymphocytes (EBVSTs), and are effective in treating these diseases. These EBVSTs are experimental and not yet approved by the Food and Drug Administration (FDA).

Sometimes it is not possible to grow these cells; or they may not last very long in the body after being given into the vein thereby having only limited time to fight the tumor. With this study, investigators aim to increase the duration of time that the T cells can last in the body and can effectively fight the cancer by using nivolumab. Nivolumab is FDA approved for treatment of other kinds of cancer like lung cancer and a skin cancer called Melanoma.

The purpose of this study is to find out if EBVST cells in combination with nivolumab are safe, to learn what the side effects are, and to see whether this therapy may help patients with EBV related lymphoma or LPD.

Detailed Study Description

The investigators will draw blood from the subject to make EBV-specific cytotoxic T-lymphocytes (EBVSTs) in the lab. Investigators will make the cells by first growing a special type of cells called dendritic cells (DCs) or monocytes to stimulate the T cells. Then they will add specially produced mixtures of proteins that included the LMP, EBNA1, and BARF proteins. These are used to stimulate T cells. As the T cells grow, investigators add some of the subject's cells expressing these proteins to stimulate them. They also add a cell called K562 that has had new genes put inside it so it expresses proteins that stimulate the immune system to encourage the T cells to grow. This stimulation trains the EBVSTs to kill cells with EBV proteins on their surface. These cells will be grown and frozen.

The cells grown in the lab will be thawed and injected into the subject's vein over 2-10 minutes. Initially, one dose of the drug nivolumab is given one day before the EBVST cells are infused (on day 0) and then every 2 weeks for a total of four doses of nivolumab. Subjects will receive two infusions of the EBVST cells. The first infusion will be given on Day 1 and a second infusion of T cells on Day 15.

If eligible, subjects may receive up to three additional doses of the T cells 6-12 weeks apart and each additional T cell infusion would be preceded by one dose of nivolumab a day prior.

Subjects will have medical and blood tests at predetermined time points. Investigators will follow subjects closely after treatment for any side effects for at least for 1 year after the subject's last infusion.
