The main aims of this clinical study are to find out the maximum dose that can be given safely to patients, the potential side effects of the drug and how they can be managed. The study will also look at what happens to Anti-CD19 (DI-B4) inside the body.
DI-B4 is a type of drug called an Anti-CD19 monoclonal antibody which is being used to stop the growth and kill cancerous immune cells by targeting the B-cell marker (CD-19) expressed on their surface. This drug has not been given to patients before.
DI-B4 is a humanised, low-fucosylated anti-CD19 Immunoglobulin (Ig) G1 monoclonal antibody with potent antibody-dependent cell-mediated cytotoxicity (ADCC) but minimal complement dependent cytotoxicity (CDC). The target antigen, CD19, is the canonical B-cell marker that is expressed on all B-cells including the malignant B-cells in NHL, CLL and acute lymphoblastic leukaemia (ALL). The CD19 antigen is therefore an attractive B-cell lineage specific target for monoclonal antibody therapy. DI-B4 is expected to act through the depletion of normal and malignant CD19 positive cells, primarily via ADCC.
