A recently granted patent (Publication Number: US11827716B2) discloses a range of claims related to a D Domain target binding polypeptide that specifically binds CD123. The patent covers various aspects, including a polypeptide fused to a heterologous polypeptide, labeled or conjugated to a therapeutic agent, isolated polynucleotides encoding the polypeptide, methods of production, pharmaceutical compositions, and chimeric antigen receptors (CARs) incorporating the D domain. The CARs further include transmembrane and intracellular signaling domains, with specific amino acid sequences provided in the claims. Additionally, the patent describes adapters for delivering an immune response to target cells, methods of killing target cells or treating cancer, and compositions for administering to patients.
Furthermore, the patent details methods of delivering an immune response to target cells, killing target cells, or treating cancer in patients by administering cells expressing the CAR or adapters comprising the D domain that binds to CD123 and an AFP p26 antigenic determinant. The claims encompass various scenarios involving the administration of cells expressing CARs with specific domains and sequences, as well as the use of adapters in conjunction with these cells. The methods outlined in the patent aim to provide targeted immune responses, particularly in the context of hematological cancers like acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome, utilizing the specified polypeptides, polynucleotides, and compositions described in the claims.
