Summary

Patients have a type of blood cell cancer or other blood problem that is very hard to cure with standard treatments and s/he will receive a bone marrow transplant. If the patient does not have a brother or sister whose marrow is a "perfect match", this bone marrow will come from a donor whose marrow is the best match available. This person may be a close relative or an unrelated person whose bone marrow best "matches" the patient's, and who agrees to donate marrow.

In normal people, the Epstein-Barr (EB) virus infection causes a flu like illness and usually gets better when the immune system controls the infection. The virus, however, remains hidden in the body for life. After a transplant, while the new immune system is growing back, the EB virus can come out and infect cells and cause them to grow in an uncontrolled manner. Patients can develop fevers, swollen lymph nodes and damage to other organs such as kidneys and lungs. This infection acts like a cancer because the cells infected with EB virus grow very quickly and there is no known effective treatment. This sort of infection will occur in between 10-30% of patients receiving a transplant from a donor who is not a perfect match, and has been fatal in nearly all these cases.

This infection occurs because the immune system cannot control the growth of the cells. We want to see if we can prevent it from happening or treat it by giving the patient a kind of white blood cell called T cells that we have grown from the marrow donor. These cells have been trained to attack EB virus infected cells. We will grow these T cells from blood taken from the donor at the time of bone marrow harvest. These T cells will be stimulated with the donor's EB virus-infected cells which have been treated with radiation so they cannot grow. After mixing these cells together we will be able to grow special T cells from the donor that can attack EB virus infected cells. We will then collect the T cells and make sure they can kill the virus infected cells. These EBV specific T cells are an investigational product not approved by the Food and Drug Administration.

Conditions

  • Epstein-Barr Virus Infections

Interventions

BIOLOGICAL

EBV specific T cells

One injection of 2x10\^7 cells/m2 from Day 45 post transplant. If EBV DNA levels remain elevated above 1000 copies/ug or the patient has persistent disease they will be eligible to receive up to 5 additional injections of CTLs at the original dose at monthly intervals.
