The invention relates to a composition comprising an anchor region capable of binding to a plasma cell; and a binding region associated with the anchor region, wherein the binding region binds a specific plasma cell antibody.

A chimeric antigen receptor (CAR), including an antigen-binding domain, a CD8 or CD28 hinge domain, a DAP10 cytoplasmic domain, a 2B4 cytoplasmic domain, and a CD3z cytoplasmic domain, where the CAR is expressed in natural killer (NK) cells. A method for treating cancer, including administering a therapeutically effective amount of a composition containing a NK cell that expresses the CAR, or a therapeutically effective amount of a cellular therapeutic agent containing a NK cell that expresses the CAR, to a subject in need thereof.

A fusion protein comprising: a first component comprising an antibody, or a fragment or variant thereof; and a second component comprising a cytokine trap or an adenosine deaminase or a fragment or variant thereof. In certain embodiments, the antibody is an anti-PD-1 antibody. In certain embodiments, the antibody binds to a tumor antigen, for example a MUC16 or MUC1 antigen. In certain embodiments, the cytokine trap is a TGF- trap. A polynucleotide encoding such a fusion protein and a vector comprising such a polynucleotide. A composition comprising the fusion protein. A method of using the composition, including in the treatment of cancer.

A pharmaceutical product comprising (a) a conjugation product of TNF and a tumour- or tumour vasculature-targeting peptide comprising an NGR, DGR, isoDGR or RGD motif; and (b) a cell comprising a chimeric antigen receptor (CAR), wherein the CAR comprises an antigen-specific targeting domain which targets a tumour antigen.

The present invention concerns compositions and methods of use of T-cell redirecting complexes, with at least one binding site for a T-cell antigen and at least one binding site for an antigen on a diseased cell or pathogen. Preferably, the complex is a DNL complex. More preferably, the complex comprises a bispecific antibody (bsAb). Most preferably, the bsAb is an anti-CD3anti-CD19 bispecific antibody, although antibodies against other T-cell antigens and/or disease-associated antigens may be used. The complex is capable of targeting effector T cells to induce T-cell-mediated cytotoxicity of cells associated with a disease, such as cancer, autoimmune disease or infectious disease. The cytotoxic immune response is enhanced by co-administration of interfon-based agents that comprise interferon-, interferon-, interferon-1, interferon-2 or interferon-3.

Ligand-cytotoxic drug conjugates, pharmaceutical compositions, preparation methods, and pharmaceutical uses thereof are provided. More specifically, a ligand-cytotoxic drug conjugate of general formula Pc-(X-Y-D).sub.n is provided. The ligand-cytotoxic drug conjugate can be used to treat cancer via receptor modulation.

An isolated polynucleotide comprising the element of: a promoter element that drives expression of the CC motif ligand 5 (a CCL5 promoter) operatively linked to a polynucleotide encoding a fusion polypeptide comprising the Fc and hinge regions of a human IgG CD44 variant 6 (CD44v6) polypeptide is described.

A method of manufacturing of Natural Killer (NK) Cells genetically modified with lentiviral vectors carrying a polynucleotide coding for a Chimeric Antigen Receptors (CARs). CAR-NK cells obtained with the method, and the use of the CAR-NK cells in medicine, in particular for use in a method of treating cancer is also disclosed.

Antibodies having binding specificity to CD44 v7/8, (a.k.a. CD44 variant 7/8) and antibody-drug conjugates (ADCs) or chimeric antigen receptors comprising such. Also provided herein are uses the anti-CD44 v7/8 antibodies, the ADCs, or immune cells expressing the chimeric antigen receptors for therapeutic and diagnostic purposes.
