Provided herein are uses of fibroblast growth factor receptor 2 (FGFR2) inhibitors in cancer treatment, in some cases in combination with immune stimulating agents, such as inhibitors of PD-1 or PD-L1. In some embodiments, FGFR2 inhibitors may comprise FGFR2 antibodies or FGFR2 extracellular domain (ECD) polypeptides, or FGFR2 ECD fusion molecules comprising an FGFR2 ECD and a fusion partner. In some embodiments, PD-1/PD-L1 inhibitors may comprise anti-PD-1 antibodies such as antibodies that bind to PD-1 or to PD-L1 and inhibit interactions between these proteins, as well as PD-1 fusion proteins or polypeptides.

An isolated cytotoxic T-lymphocyte (CTL), said CTL being a tolerance inducing cell and substantially depleted of alloreactivity, and wherein said CTL does not comprise a central memory T-lymphocyte (Tcm) phenotype, the CTL being transduced to express a cell surface receptor comprising a T cell receptor signaling module, is disclosed. Methods of generating same and using same are also disclosed.

The present invention pertains to humanized anti-Lewis Y antibodies which specifically bind to Lewis Y and do not show any cross-reactivity. Especially, the humanized anti-Lewis Y antibodies do not bind to Lewis b or any other blood group carbohydrate antigen. In particular, the present invention is directed to humanized anti-Lewis Y antibodies which are useful in the treatment of cancer.

The present technology relates to the use of protein conjugates including a self-assembly and disassembly (SADA) polypeptide and a GD2-specific antigen binding domain for preventing or mitigating off-target tissue toxicity, such as brain, kidney, and/or myeloid damage, in a subject undergoing targeted alpha radioimmunotherapy. Also disclosed herein are pretargeted radioimmunotherapy (PRIT) methods that improve the durability of the anti-GD2-SADA conjugate anti-tumor response in vivo.

A therapeutic molecule (single chain-based antibody or ligand-based) optimized for expression and secretion from engineered T cells, which may be gamma delta (gd) T cells. When expressed from engineered gdT cells, the STAR will be secreted and mediate engagement between gdT cells and antigen/receptor on target cells. Binding mediates the formation of a cytolytic synapse between the gdT cell and the target cell leading to activation the gdT cells to release proteolytic enzymes that kill target cells.

Disclosed herein are multi-specific antibody constructs that simultaneously bind two tumor cell surface antigens, GD2 and B7H3. The monovalent arms targeting GD2 and B7H3 are each low to moderate affinity for their respective antigens. The multi-specific antibodies disclosed herein bind to target tumor cells when both arms of the antibody bind to their antigens, resulting in high specificity of the antibody for GD2 and B7H3 expressing tumor cells.

Disclosed is a method for delivery of an anti-cancer agent into a cell expressing the OAcGD2 ganglioside by using an antibody recognizing the OAcGD2 ganglioside.

Disclosed are nucleic acid constructs comprising a promoter; a nucleic acid sequence encoding a single-chain variable fragment (scFv); a nucleic acid sequence encoding a notch transmembrane domain; and a nucleic acid sequence encoding a transcription factor. Disclosed are vectors comprising any of the disclosed nucleic acid constructs. Disclosed are proteins comprising a scFv; a notch transmembrane domain; and a transcription activator. Disclosed are methods of increasing human leukocyte antigen class I (HLA-I) on the surface of a tumor cell in a subject comprising administering to the subject one or more of the recombinant cells or compositions comprising a recombinant cell disclosed herein.

The present disclosure provides isolated monoclonal antibodies, particularly human monoclonal antibodies that specifically bind to Fucosyl-GM1 with high affinity. Nucleic acid molecules encoding the antibodies of this disclosure, expression vectors, host cells and methods for expressing the antibodies of this disclosure are also provided. Immunoconjugates, bispecific molecules and pharmaceutical compositions comprising the antibodies of this disclosure are also provided. This disclosure also provides methods for detecting Fucosyl-GM1, as well as methods for treating various diseases, including cancer, using anti-Fucosyl-GM1 antibodies.

Provided are NK-92 cells expressing a chimeric antigen receptor (CAR). The CAR can comprise an intracellular domain of FcϵRIγ. Also described are methods for treating a patient having or suspected of having a disease that is treatable with NK-92 cells, such as cancer or a viral infection, comprising administering to the patient NK-92-CAR cells.
