Publication number: 20220002434Abstract: Provided herein, inter alia, are isolated antibodies that bind an extracellular domain of a human SIRP-? v1 polypeptide (e.g., the D1 domain), an extracellular domain of a human SIRP-? v2 polypeptide, or both. In some embodiments, the antibodies also bind an extracellular domain of a monkey SIRP-? polypeptide, an extracellular domain of a mouse SIRP-? polypeptide, an extracellular domain of a human SIRP-? polypeptide, and/or an extracellular domain of a human SIRP-? polypeptide. In some embodiments, the antibodies block or do not binding between an extracellular domain of a human SIRP-? polypeptide and an IgSF domain of a human CD47 polypeptide, while in some embodiments, the antibodies reduce the affinity of a human SIRP-? polypeptide for binding an IgSF domain of a human CD47 polypeptide. Further provided herein are methods, polynucleotides, vectors, and host cells related thereto.Type: ApplicationFiled: June 2, 2021Publication date: January 6, 2022Inventors: Jaume PONS, Bang Janet SIM, Hong WAN, Tracy Chia-Chien KUO, Steven Elliot KAUDER, William Don HARRIMAN, Shelley IZQUIERDO

Patent number: 11208459Abstract: The present disclosure features signal-regulatory protein ? (SIRP-?) polypeptides and constructs that are useful, e.g., to target a cell (e.g., a cancer cell or a cell of the immune system), to increase phagocytosis of the target cell, to eliminate immune cells such as regulatory T-cells, to kill cancer cells, to treat a disease (e.g., cancer) in a subject, or any combinations thereof. The SIRP-? constructs include a high affinity SIRP-? D1 domain or variant thereof that binds CD47 with higher affinity than a wild-type SIRP-?. The SIRP-? polypeptides or constructs include a SIRP-? D1 variant fused to an Fc domain monomer, a human serum albumin (HSA), an albumin-binding peptide, or a polyethylene glycol (PEG) polymer. Compositions provided herein include (i) a polypeptide including a signal-regulatory protein ? (SIRP-?) D1 variant and (ii) an antibody.Type: GrantFiled: March 20, 2020Date of Patent: December 28, 2021Assignee: ALX Oncology Inc.Inventors: Jaume Pons, Bang Janet Sim, Steven Elliot Kauder, Hong Wan, Tracy Chia-Chien Kuo
