4. CD47-SIRPα as a Therapeutic Target. Even if the signaling cascade of CD47 and its role as a biomarker remain incompletely understood, there is an increasing amount of evidence suggesting that the CD47-SIRPα axis is a potential therapeutic target for the treatment of

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

Acute myelogenous leukemia (AML) is maintained by self-renewing leukemia stem cells (LSC) which evade phagocytosis through increased CD47 expression 2, 4 . CD47 expressed on circulating blood cells and vascular endothelium serves as a sink for intravenously administered therapeutic CD47 antibodies and leads to the commonly observed side effects of transient anemia, hyperbilirubinemia, thrombocytopenia, and lymphopenia. 2020-04-15 · CD47 (cluster of differentiation 47), also referred to as integrin associated protein (IAP) [ 5] and ovarian cancer antigen (OA3) [ 6 ], is a ubiquitously expressed transmembrane protein that belongs to the immunoglobulin superfamily. CD47 plays an important role in multiple fundamental cellular functions, including apoptosis, proliferation, 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. Results: 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. A number of therapeutics that target the CD47/SIRPα axis are under preclinical and clinical investigation.

It has an extracellular N -terminal IgV domain, five transmembrane domains, and a short C-terminal cytoplasmic tail. 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.

除了以上5家公司，包括TG Therapeutics、OSE Immuno therapeutics、Novimmune SA、KAHR Medical、EpicentRx 5家公司在内以及其他的海外公司在CD47领域也均有布局，因篇幅限制，这里就不作展开。国内篇相较海外，中国无疑是CD47的又一主要战场。 2021-03-04 · ALX Oncology’s lead product candidate, ALX148, is a next generation CD47 blocking therapeutic that combines a high-affinity CD47 binding domain with an inactivated, proprietary Fc domain. Preclinical studies have shown that interrupting the CD47-SIRPα signaling pathway promotes anti-tumor activity against human cancers, both in vitro and in vivo. Thus, blocking CD47 has emerged as a promising therapeutic strategy with early clinical data demonstrating benefit to cancer patients.

CD47, known as an integrin-associated protein, was first identified as a transmembrane protein from red blood cells (RBC) . Hence, CD47 has been identified as a novel therapeutic target in cancers, including multiple myeloma (MM) which is localized mainly in the bone marrow (BM). MM cells rely heavily on the interactions with tumor microenvironment (TME) and immune system.

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.
