Provided herein are chimeric receptors, including chimeric antigen receptors (CARs), comprising BCMA-binding molecules, including anti-BCMA antibodies and antigen-binding fragments thereof, including heavy chain variable (V) regions and single-chain antibody fragments, and encoding polynucleotides. In some embodiments, the anti-BCMA chimeric receptors specifically bind to BCMA. Among the anti-BCMA-binding molecules are human antibodies, including those that compete for binding to BCMA with reference antibodies, including a non-human reference antibody. Also provided are genetically engineered cells expressing the CARs and uses thereof including in adoptive cell therapy.

Chimeric antigen receptors specific for B-cell maturation antigen and encoding polynucleotides

Provided are ROR1 binding molecules, including anti-ROR1 antibodies, including antibody fragments such as variable heavy chain (VH) regions, single-chain fragments, and chimeric receptors including the antibodies, such as chimeric antigen receptors (CARs). In some embodiments, the antibodies specifically bind to ROR1. Among the antibodies are human antibodies, including those that compete for binding to ROR1 with reference antibodies, such as a non-human reference antibody. Also provided are genetically engineered cells expressing the chimeric receptors, and uses of the binding molecules and cells adoptive cell therapy.

Antibodies and chimeric antigen receptors specific for ROR1

Provided are CD19 binding molecules, including anti-CD19 antibodies, including antibody fragments such as single-chain fragments, and chimeric receptors including the antibodies, such as chimeric antigen receptors (CARs). Among the antibodies are human antibodies, including those that compete for binding to CD19 with reference antibodies, such as murine antibodies. In some embodiments, the antibodies display similar functional properties to the reference antibodies, such as comparable binding affinities and/or competitive inhibition properties. Also provided are genetically engineered cells expressing the chimeric receptors, and uses of the binding molecules and cells adoptive cell therapy.

Antibodies and chimeric antigen receptors specific for CD19

Provided herein are BCMA-binding molecules, including anti-BCMA antibodies and antigen-binding fragments thereof such as heavy chain variable (VH) regions and single-chain antibody fragments, and chimeric receptors comprising the anti-BCMA binding molecules such as chimeric antigen receptors (CARs). In some embodiments, the anti-BCMA antibodies or antigen-binding fragments thereof specifically bind to BCMA-1. Among the anti-BCMA antibodies are human antibodies, including those that compete for binding to BCMA with reference antibodies, such as a non-human reference antibody. Also provided are genetically engineered cells expressing the CARs or BCMA-binding molecules and uses thereof such as in adoptive cell therapy.

Antibodies and chimeric antigen receptors specific for B-cell maturation antigen

The invention provides methods and compositions for identifying binding polypeptides (e.g., antibodies or antigen binding fragments thereof) that specifically binds to a cell-surface antigen. The methods of the invention generally comprise contacting a variegated nucleic acid-display library of binding polypeptides with a cell-surface antigen displayed on the exterior surface of a cell; and isolating from the library at least one library member that specifically binds to the cell-surface antigen on the exterior surface of the cell.

Target antigen discovery, phenotypic screens and use thereof for identification of target cell specific target epitopes

Provided are methods and compositions for identifying binding polypeptides (e.g., antibodies or antigen binding fragments thereof) that specifically binds to a cell-surface antigen. The methods of the invention generally comprise contacting a variegated nucleic acid-display library of binding polypeptides with a cell-surface antigen displayed on the exterior surface of a cell; and isolating from the library at least one library member that specifically binds to the cell-surface antigen on the exterior surface of the cell. Also provided are novel nucleic acid display libraries (e.g., DNA display libraries) useful in the methods of the invention.

Methods and compositions for generation of binding agents against cell surface antigens

Provided herein are chimeric receptors, such as chimeric antigen receptors (CARs), comprising BCMA-binding molecules, such as anti-BCMA antibodies and antigen-binding fragments thereof, such as heavy chain variable (V) regions and single-chain antibody fragments, and encoding polynucleotides. In some embodiments, the anti-BCMA chimeric receptors specifically bind to BCMA. Among the anti-BCMA-binding molecules are human antibodies, including those that compete for binding to BCMA with reference antibodies, such as a non-human reference antibody. Also provided are genetically engineered cells expressing the CARs and uses thereof such as in adoptive cell therapy.
