CD-47 acts as a don't eat me signal to macrophages of the immune system which has made it a potential therapeutic target in some cancers, and more recently, for the treatment of pulmonary fibrosis. CD47 Moreover, CD47 overexpression may blunt the therapeutic action of monoclonal antibodies, and therefore, CD47 blockade would enhance antibody efficacy . Additional strategies to block this axis involve engineered SIRPα monomers or exosomes with SIRPα that have a high affinity for CD47 and that would similarly lower the macrophage threshold for phagocytosis and, as a result, T cell activation Therapeutic blockade of the CD47-SIRPα pathway has led to robust pre-clinical efficacy in vivo with several therapeutics in clinical development. While the clinical data of such agents in myeloid malignancies has been limited, initial data with magrolimab, a first-in-class anti-CD47 antibody, has been shown to be well-tolerated with encouraging efficacy results when combined with azacitidine Trillium Therapeutics has two lead candidates that encourage immune cells known as “macrophages” to gobble up cancer cells by blocking a protein known as CD47. However, the CD47 inhibitor To describe the relevance of CD47 in the tumor microenvironment and summarize data on anti-CD47 therapies, including its role in cutaneous T-cell lymphoma (CTCL). Recent findings .

By blocking this “don’t eat me” signal with decoy receptors, we aim to unmask tumor cells and make them visible to, and eradicated by, the immune system. BioSuperior™ Anti-CD47 Therapeutic Antibody (AVI-105) Our Company AbVision, Inc. (AVI) previously the Drug Discovery Group of BioVision Inc., is a privately held biopharmaceutical company headquartered in the San Francisco Bay Area. CD47 also known as integrin associated protein is a transmembrane protein that in humans is encoded by the CD47 gene. CD47 belongs to the immunoglobulin superfamily and partners with membrane integrins and also binds the ligands thrombospondin-1 and signal-regulatory protein alpha. CD-47 acts as a don't eat me signal to macrophages of the immune system which has made it a potential therapeutic target in some cancers, and more recently, for the treatment of pulmonary fibrosis.

Several papers highlight a difference between CD47 +/+ and CD47 -/- tumor cells removal upon 4N1K treatment22.

The MIAP301 antibody has By enhancing both innate and adaptive immunity, CD47 blocking antibody and could also have amenable therapeutic potential against infectious diseases. Conclusions: Our research provided evidence that CD47 blockade could sensitize NSCLC to anti-angiogenic therapy and potentiate its anti-tumor effects by The Interaction Between Signal Regulatory Protein Alpha (SIRPα) and CD47: Structure, Function, and Therapeutic Target.

Trillium Therapeutics is a leader in the CD47 inhibitor space in terms of data claims, and Pfizer has recently taken an interest. Our internal anti-CD47 program has now yielded two clinical candidates, a signal of our continued commitment to the development of innovative, safe and efficacious cancer treatments in addition to our commitment to fighting COVID-19.” About Sorrento Therapeutics, Inc. Provided are anti-CD47 monoclonal antibodies (anti-CD47 mAbs) with distinct functional profiles as described herein, methods to generate anti-CD47 mAbs, and to methods of using these anti-CD47 mAbs as therapeutics for the prevention and treatment of solid and hematological cancers, ischemia-reperfusion injury, cardiovascular diseases, autoimmune diseases, inflammatory diseases or as Therapeutic antitumor antibodies are widely used clinically. CD47 is an antiphagocytic ligand expressed by tumors that binds the inhibitory receptor signal regulatory protein alpha (SIRPα) on phagocytic cells. Interruption of CD47–SIRPα interactions in immunodeficient mice bearing human tumors enhances therapeutic antitumor antibody responses by promoting phagocytosis of antibody-bound 2019-12-11 · Metastatic xenograft models and VEGFR1-SIRPα fusion protein were applied to evaluate the therapeutic effect of simultaneous disruption of angiogenetic axis and CD47-SIRPα axis. Up-regulation of an innate immunosuppressive pathway, CD47, the ligand of the negative immune checkpoint regulator SIRPα (signal regulatory protein alpha), was observed in NSCLC tumors during anti-angiogenic therapy. 2021-03-02 · The other anti-CD47 antibody (IMC-002) discovered from the G-MAB library was previously cleared by the FDA, and is currently in Phase 1 human studies sponsored by ImmuneOncia Therapeutics, LLC, a Learn about the first commercially-available SIRPα/CD47 cell-based assay -- PathHunter SIRPα Signaling Assay.
