Abstract
D domain (DD) containing polypeptides (DDpp) that specifically bind targets of interest (e.g., BCMA, CD123, CS1, HER2, AFP, and AFP p26) are provided, as are nucleic acids encoding the DDpp, vectors containing the nucleic acids and host cells containing the nucleic acids and vectors. DDpp such as DDpp fusion proteins, are also provided as are methods of making and using the DDpp. Such uses include, but are not limited to diagnostic and therapeutic applications.
Claims11
A method for treating myeloma or lymphoma in a subject in need thereof, comprising administering to the subject a chimeric antigen receptor (CAR) comprising no more than one D Domain (DD) that specifically binds B Cell Maturation Antigen (BCMA) and comprises an amino acid sequence having at least 90% sequence identity to SEQ ID NO:
- 168.
A method for treating myeloma or lymphoma in a subject in need thereof, comprising administering to the subject a chimeric antigen receptor (CAR) which comprises a transmembrane domain and a target binding domain comprising a D Domain (DD) which specifically binds B Cell Maturation Antigen (BCMA) and comprises an amino acid sequence having at least 90% sequence identity to SEQ ID NO:
- 168.
A method for treating multiple myeloma or lymphoma in a subject in need thereof, comprising administering to the subject a cell comprising a chimeric antigen receptor (CAR), wherein the CAR comprises:
- (a) a target binding domain comprising a D Domain (DD) which specifically binds B Cell Maturation Antigen (BCMA) and comprises the amino acid sequence of SEQ ID NO:
- 168;
- (b) a CD8 transmembrane domain;
- and
- (c) an intracellular signaling domain of 4-1BB.
