Embodiment approach

[0077] One aspect of the present disclosure is a combination comprising a CD19 specific antibody and a Bruton's tyrosine kinase (BTK) inhibitor for the treatment of non-Hodgkin's lymphoma, chronic lymphocytic leukemia and / or acute lymphoblastic leukemia . In an embodiment, the combination is synergistic.

[0078] Herein, the combination of an exemplary anti-CD19 antibody and ibrutinib performed synergistically in an in vitro model associated with CLL. Since CLL is a B cell-associated disease and CD19 is highly expressed on B cells, exemplary combinations should have the same mechanism of action and should also show synergy in the treatment of other B cell-associated disorders such as ALL and NHL. Therefore, the combination of an exemplary CD19-specific antibody and ibrutinib should be effective in the treatment of non-Hodgkin's lymphoma, chronic lymphocytic leukemia and / or acute lymphoblastic leukemia in humans. Clinical trials will confirm the expected efficacy of the combi...

[0108] Example 1: Cytotoxicity in MEC-1 cells using MOR00208 and ibrutinib alone and in combination

[0109] Material

[0110] Cell line tested: MEC-1 cells (DSMZ #ACC497). Test cell lines: chronic B-cell leukemia cell line; mantle cell lymphoma cell line JVM-2 ( CRL-3002); Ramos cells (ATCC No. CRL-1596); Human Burkitt's Ramos cells (ATCC No. CRL-1596); HG-3 (DSMZ #ACC765) and Cll (DSMZ #ACC773) are chronic lymphoid cell leukemia cell line; Su-DHL 6 (DSMZ #ACC572), U2932 (DSMZ #ACC633) and OCI-LY7 (DSMZ #ACC688) are diffuse large B-cell lymphoma (DLBCL) cell lines; JVM-2 ( CRL-3002) is a mantle cell lymphoma cell line; and BALL-1 (DSMZ #ACC742) is an acute lymphoblastic leukemia cell line.

Abstract

The present disclosure describes a pharmaceutical combination of an anti-CD19 antibody and a Bruton's tyrosine kinase (BTK) inhibitor for the treatment of non-Hodgkin's lymphoma, chronic lymphocytic leukemia and / or acute lymphoblastic leukemia.

Description

technical field [0001] The present disclosure relates to pharmaceutical combinations of anti-CD19 antibodies and Bruton's tyrosine kinase (BTK) inhibitors for the treatment of non-Hodgkin's lymphoma, chronic lymphocytic leukemia and / or acute lymphoblastic leukemia . Background technique [0002] B cells are lymphocytes that play an important role in the humoral immune response. They are produced in the bone marrow of most mammals and comprise 5-15% of the circulating lymphatic pool. The main function of B cells is to produce antibodies against various antigens, and B cells are an important component of the adaptive immune system. [0003] Due to the critical role of B cells in regulating the immune system, its dysregulation has been linked to various diseases such as lymphoma and leukemia. These include non-Hodgkin's lymphoma (NHL), chronic lymphocytic leukemia (CLL) and acute lymphoblastic leukemia (ALL). [0004] NHL is a heterogeneous malignancy derived from lymphocyt...
