Allo CD7 CAR WU-CART-007

The purpose of this study is to determine thesafety and tolerability of an experimental form of therapy, known as WU-CART-007("study drug"). WU-CART-007 uses immunecells, called T cells, that are genetically changed to identify cancer cells.In this study, T cells are collected from a healthy human donor and have beenmodified in a laboratory. If the genetically changed T cells recognize andattach to cancer cells, they may have the ability to kill those cancer cells.

Patients with T-cell Acute Lymphoblatic Leukemia (T-ALL) orLymphoblastic Lymphoma (LBL), where the disease has come back (relapsed) or hasnot responded to treatment (refractory) may be eligible for the study.
