Disclosed herein are compositions and methods of use comprising hexavalent DNL complexes. Preferably, the complexes comprise anti-CD20 and/or anti-CD22 antibodies or fragments thereof. More preferably, the anti-CD20 antibody is veltuzumab and the anti-CD22 antibody is epratuzumab. Administration of the subject hexavalent DNL complexes induces apoptosis and cell death of target cells in diseases such as B-cell lymphomas or leukemias, autoimmune disease or immune dysfunction disease. In most preferred embodiments, the DNL complexes increase levels of phosphorylated p38 and PTEN, decrease levels of phosphorylated Lyn, Akt, ERK, IKKα/β and IκBα, increase expression of RKIP and Bax and decrease expression of Mcl-1, Bcl-xL, Bcl-2, and phospho-BAD in target cells. The subject DNL complexes show EC.sub.50 values for inhibiting tumor cell growth in the low nanomolar or even sub-nanomolar concentration range.

The present invention relates to immunotherapeutic approaches to treating haematological cancers. In particular the invention relates to a method for treating a haematological cancer by targeting the 5T4 antigen. As such, the invention provides a method for treating haematological cancers comprising administering to a subject a 5T4-targeting agent. The invention also provides a 5T4-specific chimeric antigen receptor (CAR) and uses thereof in treating cancers.

The present disclosure relates to novel dosage regimes for the treatment of pathological conditions, such as cancer, with Antibody Drug Conjugates (ADCs). In particular, the present disclosure relates to novel dosage regimes for the administration of ADCs which bind to CD25 (CD25-ADCS). ##STR00001##

Provided herein are methods of treating B-cell proliferative disorders (such as Diffuse Large B-Cell Lymphoma “DLBCL”) using immunoconjugates comprising anti-CD79b antibodies in combination with an alkylating agent (such as bendamustine) and an anti-CD20 antibody (such as rituximab).

Disclosed herein are improved compositions and methods involved in treating hematologic cancers, i.e., cancers that begin in blood-forming tissue, such as the bone marrow, or in the cells of the immune system. The compositions comprise complexes containing albumin-containing nanoparticles (e.g., ABRAXANE® nanoparticles) and antibodies. The compositions are used to effect hematologic cancer cell death.

Linker-drug compounds and antibody-drug conjugates that bind to human oncology targets are disclosed. The linker-drug compounds and antibody-drug conjugates comprise a herboxidiene splicing modulator drug moiety. The disclosure further relates to methods and compositions for use in the treatment of neoplastic disorders by administering the antibody-drug conjugates provided herein. The herboxidiene itself is also claimed. Further claims are directed to its use, and to the use of a neoantigen, generated by the herboxidiene or its ADC, or a vaccine against this neoantigen.

Methods are provided to manipulate phagocytosis of cells, including hematopoietic cells, e.g. circulating hematopoietic cells, bone marrow cells, acute leukemia cells, etc.; and solid tumor cells. In some embodiments of the invention the circulating cells are hematopoietic stem cells, or hematopoietic progenitor cells, particularly in a transplantation context, where protection from phagocytosis is desirable. In other embodiments the circulating cells are leukemia cells, particularly acute myeloid leukemia (AML), where increased phagocytosis is desirable.

Disclosed herein are improved compositions and methods involved in treating hematologic cancers, i.e., cancers that begin in blood-forming tissue, such as the bone marrow, or in the cells of the immune system. The compositions comprise complexes containing albumin-containing nanoparticles (e.g., ABRAXANE® nanoparticles) and antibodies. The compositions are used to effect hematologic cancer cell death.

Disclosed herein are Interleukin 1 Receptor Accessory Protein (IL1RAP) antibodies and antibody drug conjugates (ADCs), including compositions and methods of using said antibodies and ADCs.

The invention provides an agent for preventing or treating a condition characterised by the presence of unwanted cells, the agent comprising: (i) a targeting moiety that is capable of targeting to the unwanted cells; and (ii) a T cell antigen, wherein the T cell antigen can be released from the targeting moiety by selective cleavage of a cleavage site in the agent in the vicinity of the unwanted cells.
