Provided herein are chimeric antigen receptors that binds specifically to B-cell maturation antigen (BCMA) and CD307e, nucleic acids that encode these chimeric antigen receptors, and methods of making and using these chimeric antigen receptors.

Embodiments of the present disclosure relate to a polynucleotide encoding a CAR comprising a cytoplasmic domain of CD4, or a CAR comprising SEQ ID NO: 17 in its intracellular domain, and the cytoplasmic domain of CD4 is located between a transmembrane domain of the CAR and a signaling or stimulatory domain, for example, CD3 zeta domain.

The present invention is directed to a monoclonal anti-human BCMA antibody, or a single-chain variable fragment (scFv), comprising V.sub.H having the amino acid sequence of SEQ ID NO: 6 and V.sub.L having the amino acid sequence of SEQ ID NO: 7. The present invention is also directed to a BCMA chimeric antigen receptor (CAR) comprising from N-terminus to C-terminus: (i) a single-chain variable fragment (scFv) of the present invention, (ii) a transmembrane domain, (iii) at least one co-stimulatory domains, and (iv) an activating domain. The monoclonal antibody of the present invention exhibits selective and high-affinity binding to BCMA. BCMA CAR-T cells based on BCMA scFv of the present invention significantly decreases multiple myeloma tumor growth in an animal model.

The present disclosure provides improved chimeric co-stimulatory receptors (CCRs), fusion proteins, genetically modified immune effector cells, and use of these compositions to treat disease.

Provided herein is are methods of using 4-(4-(4-(((2-(2,6-dioxopiperidin-3-yl)-1-oxoisoindolin-4-yl)oxy)methyl)benzyl)piperazin-1-yl)-3-fluorobenzonitrile, or an enantiomer, a mixture of enantiomers, a tautomer, or a pharmaceutically acceptable salt thereof and a bispecific antibody specifically binding to human B cell maturation antigen (BCMA) and to human CD3? (CD3) provided herein, in treating, preventing or managing multiple myeloma.

(CD3) provided herein, in treating, preventing or managing multiple myeloma.

The present disclosure provides antibodies that specifically bind to human glucocorticoid-induced TNFR family related receptor (GITR) and compositions comprising such antibodies. In a specific aspect, the antibodies specifically bind to human GITR and modulate GITR activity, e.g., enhance, activate or induce GITR activity, utilizing such antibodies. The present disclosure also provides methods for treating disorders, such as cancer and infectious diseases, by administering an antibody that specifically binds to human GITR and modulates GITR activity e.g., enhances, activates or induces GITR activity.

The present invention relates generally to a population of stem cells (e.g., iPSCs or HSCs) that comprise nucleic acids encoding a T cell receptor and a chimeric antigen receptor directed to multiple distinct antigenic determinants, for example two distinct tumour antigenic determinants. The present invention is also directed to a population of T cells that co-express a T cell receptor and a chimeric antigen receptor directed to multiple distinct antigenic determinants, such as two distinct tumour antigenic determinants. The cells of the present invention can be derived from chosen donors whose HLA type is compatible with significant sectors of the populations, and are useful in a wide variety of applications, in particular in the context of the therapeutic treatment of neoplastic conditions.

Disclosed herein are methods for treating cancer comprising administering CAR-modified immune cells and at least one Retinoic Acid Receptor and/or Retinoid X Receptor active agent.
