Anti-CD38 antibodies for treatment of acute myeloid leukemia
The present invention relates to methods of treatment of acute myeloid leukemia with anti-CD38 antibodies.
1. A method of treating a subject having relapsed or refractory acute myeloid leukemia (AML), comprising administering to the subject in need thereof an anti-CD38 antibody comprising a heavy chain variable region (VH) of SEQ ID NO: 4 and a light chain variable region (VL) of SEQ ID NO: 5 for a time sufficient to treat relapsed or refractory AML, wherein the subject has been treated with idarubicin, cytarabine or hydroxyurea, wherein the AML is AML with at least one mutation in a gene selected from the group consisting of fins-related tyrosine kinase 3 (FLT3), nucleophosmin (NPM1), isocitrate dehydrogenase 2 (IDH2), DNA (cytosine-5) methyltransferase 3 (DNMT3A) and CCAAT/enhancer binding protein alpha (CEBPA).
2. The method of claim 1 , wherein the anti-CD38 antibody comprising the VH of SEQ ID NO: 4 and the VL of SEQ ID NO: 5 is an IgG1, IgG2, IgG3 or IgG4 isotype.
3. The method of claim 2 , wherein the anti-CD38 antibody comprising the VH of SEQ ID NO: 4 and the VL of SEQ ID NO: 5 comprises the heavy chain of SEQ ID NO: 12 and the light chain of SEQ ID NO: 13.
4. The method of claim 1 , wherein the mutation in FLT3 is FLT3-ITD, the mutation in IDH2 is R140Q or the mutation in DNMT3A is R882H.
