Clinical Trial

Disease: Refractory or recurrent B-cell Acute Lymphoblastic Leukemia, ALL, (NCT03232619)

Disease info:

B-cell acute lymphoblastic leukaemia is an aggressive (fast-growing) type of leukemia (blood cancer) 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 acute lymphoblastic leukaemia (ALL). B-ALL is also called B-cell acute lymphocytic leukaemia and precursor B-lymphoblastic leukaemia. 


The American Cancer Society’s estimates for acute lymphocytic leukemia (ALL) in the United States for 2020 are: About 6,150 new cases of ALL (3,470 in males and 2,680 in females) About 1,520 deaths from ALL (860 in males and 660 in females)

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).
