Clinical Trial

Disease: B-cell Acute Lymphoblastic Leukemia, ALL, (NCT03298828)

Disease info:

B-cell acute lymphoblastic leukaemia is an aggressive type of blood cancer that occurs because too many B-cell lymphoblasts (immature white blood cells) exist in the bone marrow and blood. It is the most common type of acute lymphoblastic leukemia (ALL). Note that B-cell ALL is also called B-cell acute lymphocytic leukaemia and precursor B-lymphoblastic leukaemia. 

The American Cancer Society’s estimates for acute lymphocytic leukaemia (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).

Phase III Safety and Efficacy

Status: Active not recruiting


The purpose of this study is to evaluate the safety, efficacy and blood kinetics of autologous T cells that are genetically modified to express a CD19-targting chimeric antigen receptor (CAR), and PD-1 knockout-engineered T cells in patients with relapsed or refractory B cell non-Hodgkin lymphoma lymphoma and leukaemia. Following informed consent and registration to the trial, patients will undergo an unstimulated leukapheresis to yield cells for generation of the CD19 CAR T-cells. Patients will receive the CD19 CAR and PD-1 knockout-engineered T-cells following lymphodepleting chemotherapy.
