An embodiment of the invention provides a chimeric antigen receptor (CAR) comprising an antigen binding domain specific for FLT3, a transmembrane domain, and an intracellular T cell signaling domain. Nucleic acids, recombinant expression vectors, host cells, populations of cells, antibodies, or antigen binding portions thereof, and pharmaceutical compositions relating to the CARs are disclosed. Methods of detecting the presence of a proliferative disorder, e.g., cancer, in a mammal and methods of treating or preventing a proliferative disorder, e.g., cancer, in a mammal are also disclosed.

FLT3-specific chimeric antigen receptors and methods using same

Human monoclonal antibodies that specifically bind Fms-like tyrosine kinase 3 (FLT3) are described. Chimeric antigen receptors (CARs) and other antibody conjugates that include the FLT3-specific monoclonal antibodies are also described. Methods for the diagnosis and treatment of FLT3-associated cancer, such as acute lymphoblastic leukemia (ALL) or acute myeloid leukemia (AML), are further described.

Human monoclonal antibodies specific for FLT3 and uses thereof

An embodiment of the invention provides bicistronic chimeric antigen receptor (CAR) amino acid constructs. Nucleic acids, recombinant expression vectors, host cells, populations of cells, and pharmaceutical compositions relating to the CAR constructs are disclosed. Methods of detecting the presence of cancer in a mammal and methods of treating or preventing cancer in a mammal are also disclosed. Methods of making the CAR constructs are disclosed.

Bicistronic chimeric antigen receptors and their uses

An affinity matured anti-CD22 human monoclonal antibody exhibiting significantly higher affinity (less than 50 pM) compared to the parental antibody (affinity of about 2 nM) is described. The anti-CD22 variant antibody or a fragment thereof, such as a single-chain variable fragment (scFv), can be used as the antigen-binding portion of chimeric antigen receptors (CARs), antibody-drug conjugates (ADCs), immunotoxins or multi-specific antibodies for the treatment of B-cell malignancies.

Affinity matured CD22-specific monoclonal antibody and uses thereof

The invention provides a chimeric antigen receptor (CAR) comprising an antigen binding domain specific for TSLPR, a transmembrane domain, and an intracellular T cell signaling domain. Nucleic acids, recombinant expression vectors, host cells, populations of cells, antibodies, or antigen binding portions thereof, and pharmaceutical compositions relating to the CARs are disclosed. Methods of detecting the presence of a proliferative disorder, e.g., cancer, in a mammal and methods of treating or preventing a proliferative disorder, e.g., cancer, in a mammal are also disclosed.

Thymic stromal lymphopoietin receptor-specific chimeric antigen receptors and methods using same

An embodiment of the invention provides a chimeric antigen receptor (C AR) comprising an antigen binding domain specific for FLT3, a transmembrane domain, and an intracellular T cell signaling domain. Nucleic acids, recombinant expression vectors, host cells, populations of cells, antibodies, or antigen binding portions thereof, and pharmaceutical compositions relating to the CARs are disclosed. Methods of detecting the presence of a proliferative disorder, e.g., cancer, in a mammal and methods of treating or preventing a proliferative disorder, e.g., cancer, in a mammal are also disclosed.

The invention provides dual specific chimeric antigen receptors (CARs) having antigenic specificity for CD19 and CD22. Nucleic acids, recombinant expression vectors, host cells, populations of cells, and pharmaceutical compositions relating to the CARs are disclosed. Methods of detecting the presence of cancer in a mammal and methods of treating or preventing cancer in a mammal are also disclosed.
