Provided herein are antibodies that specifically bind to Fms-like tyrosine kinase 3 (FLT3), chimeric antigen receptors (CARs) that specifically bind to FLT3, and engineered immune cells expressing such CARs (e.g. FLT3-specific CAR-T cells). The invention also provides making such antibodies, CARs, and engineered immune cells. The invention also provides using such antibodies, CARs, and engineered immune cells, for example for the treatment of a condition associated with malignant cells expressing FLT3 (e.g., cancer).

Chimeric antigen receptors targeting FLT3

The present invention provides antibodies that specifically bind to FLT3 (Fms-Like Tyrosine Kinase 3). The invention further provides bispecific antibodies that bind to FLT3 and another antigen (e.g., CD3). The invention further relates to antibody encoding nucleic acids, and methods of obtaining such antibodies (monospecific and bispecific). The invention further relates to therapeutic methods for use of these antibodies for the treatment of FLT3-mediated pathologies, including cancer such as Acute Myeloid Leukemia (AML).

Antibodies specific for FLT3 and their uses

Provided here are engineered immune cells that comprise a constitutively active chimeric cytokine receptor (CACCR) and a B-cell maturation antigen (BCMA) specific chimeric antigen receptor (CAR). Also provided herein are engineered immune cells that comprise one or more nucleic acids e.g. a bicistronic vector such as a viral vector that encode the CACCRs and BCMA CARs and engineered immune cells e.g. engineered autologous or allogeneic T cells that express both CACCRs and BCMA CARs from the nucleic acids. When present on chimeric antigen receptor (CAR)-bearing engineered immune cells, the CACCRs allow for increased immune cell activation, proliferation, persistence, and/or potency. Further provided herein are methods of making and using the engineered immune cells described herein, such as methods of treating a disease or condition by administering at least one appropriate dose of the cells to a patient suffering from the condition.

BCMA CAR-T cells with enhanced activities

The invention provides CARs (CARs) that specifically bind to BCMA (B-Cell Maturation Antigen). The invention further relates to engineered immune cells comprising such CARs, CAR-encoding nucleic acids, and methods of making such CARs, engineered immune cells, and nucleic acids. The invention further relates to therapeutic methods for use of these CARs and engineered immune cells for the treatment of a condition associated with malignant cells expressing BCMA (e.g., cancer).
