Abstract: The present invention relates to mono-specific and multi-specific polypeptide therapeutics that specifically target cells expressing prostate-specific membrane antigen (PSMA) and are useful for the treatment of prostate cancer (e.g., castrate-resistant prostate cancer), tumor-related angiogenesis or benign prostatic hyperplasia (BPH). In one embodiment, the multi-specific polypeptide therapeutics bind both PSMA-expressing cells and the T-cell receptor complex on T cells to induce target-dependent T-cell cytotoxicity, activation and proliferation.

Abstract: The present disclosure provides polypeptide heterodimers formed between two different single chain fusion polypeptides via natural heterodimerization of an immunoglobulin CH1 region and an immunoglobulin light chain constant region (CL). The polypeptide heterodimer comprises two or more binding domains that specifically bind one or more targets (e.g., a receptor). In addition, both chains of the heterodimer further comprise an Fc region portion. The present disclosure also provides nucleic acids, vectors, host cells and methods for making polypeptide heterodimers as well as methods for using such polypeptide heterodimers, such as in directing T cell activation, inhibiting solid malignancy growth, and treating autoimmune or inflammatory conditions.
