ARMS - Rapidly Generated Multivirus-Specific CTLs for Prophylaxis & Treatment of EBV, CMV, Adenovirus, HHV6 & BK Virus

Summary

The subjects eligible for this trial have a type of blood cell cancer, other blood disease or a genetic disease for which they will receive a stem cell transplant. The donor of the stem cells will be either the subject's brother or sister, or another relative, or a closely matched unrelated donor. The Investigators are asking subjects to participate in this study which tests if blood cells from the subject's donor that have been grown in a special way, can prevent or be a effective treatment for early infection by five viruses - Epstein Barr virus (EBV), cytomegalovirus (CMV), adenovirus, BK virus (BKV) and human herpes virus 6 (HHV6).

The Investigators have grown T cells from the subject's stem cell donor in the laboratory in a way that will train them to recognize the viruses and control them when the T cells are given after a transplant. This treatment with specially trained T cells (also called cytotoxic T cells or "CTLs") has had activity against three of these viruses (CMV, EBV and Adenovirus) in previous studies. In this study the Investigators want to see if they increase the number of viruses that can be targeted to include BKV and HHV6 using a simple and fast approach to make the cells.

The Investigators want to see if they can use a kind of white blood cell called T lymphocytes (or T cells) to prevent and treat adenovirus, CMV, EBV, BKV and HHV6 in the early stages of reactivation or infection.

• Viral Infection

Interventions

BIOLOGICAL

Multivirus-specific T cells Dose Level 1

The feasibility and safety of 3 different dose levels will be evaluated and will determine the maximum tolerated dose (MTD) level. Dose Level One: 5x10\^6 mCTLs/m2 There may be an option of administering 2 additional doses (at the same level the patient was receiving), 28 days after the first dose, in subjects that have a partial response after one dose or who receive other therapy that may affect the persistence or function of the infused CTL.

BIOLOGICAL

Multivirus-specific T cells Dose Level 2

The feasibility and safety of 3 different dose levels will be evaluated and will determine the maximum tolerated dose (MTD) level. Dose Level Two: 1x10\^7 mCTLs/m2 There may be an option of administering 2 additional doses (at the same level the patient was receiving), 28 days after the first dose, in subjects that have a partial response after one dose or who receive other therapy that may affect the persistence or function of the infused CTL

BIOLOGICAL

Multivirus-specific T cells Dose Level 3

The feasibility and safety of 3 different dose levels will be evaluated and will determine the maximum tolerated dose (MTD) level. Dose Level Three: 2x10\^7 mCTLs/m2 There may be an option of administering 2 additional doses (at the same level the patient was receiving), 28 days after the first dose, in subjects that have a partial response after one dose or who receive other therapy that may affect the persistence or function of the infused CTL
