Clinical Trial

Disease: B-cell Acute Lymphoblastic Leukaemia, B-ALL, (NCT03232619)

Disease info:

Leukaemia is cancer of the white blood cells which are responsible for fighting infection. In leukaemia, the bone marrow produces abnormal levels of white blood cells. B-cell acute lymphoblastic leukaemia (B-ALL) is an aggressive (fast-growing) type of leukaemia in which too many B-cell lymphoblasts (immature white blood cells) are found in the bone marrow and blood. It is the most common type of ALL. Also called B-cell acute lymphocytic leukaemia and precursor B-lymphoblastic leukaemia. 



ALL accounts for less than 1% of all cancers in the U.S., with around 6,540 new cases estimated in the U.S. in 2023. ALL is the most common type of cancer found in children, though it can affect adults too.

UCART is an allogeneic CAR-T cell therapy, in which CRISPR-Cas9 technology is used to disrupt the T cell receptor constant locus (TRAC) and the CD19 cell surface molecule in T cells from healthy donors. For this trial, two kinds of CD19-CART cells have been engineered. One is equipped with a murine CD19 scFv (single-chain variable fragmentt), while the other with a humanised scFv. This study aims to evaluate the safety and efficacy of both murine and humanised CD19-CART in treating refractory or recurrent B-cell acute lymphoblastic leukaemia (ALL).
