•CD47 is a widely expressed glycoprotein that delivers a “DO NOT EAT” signal to macrophages through SIRPα •Binding of CD47 to SIRPαinhibits macrophage cytoskeletal activity and in turn phagocytosis •Tumor cells frequently exploit the CD47-SIRPα axis to evade immune surveillance by macrophages •Many hematologic and solid tumors express high levels of CD47 •High CD47 expression often correlates with aggressive disease and poor clinical outcomes

CD47 is an antiphagocytic molecule that acts via ligation to signal regulatory protein alpha on phagocytes; its enhanced expression and therapeutic targeting have recently been reported for several malignancies.

Based on this key function, therapeutics targeting CD47 or its ligands thrombospondin-1 and SIRPα could have broad applications spanning reconstructive surgery, engineering of tissues and biocompatible surfaces, vascular diseases, diabetes, organ transplantation, radiation injuries, inflammatory diseases, and cancer. Strategies for targeting CD47 are becoming a hot spot for cancer therapy. The expression of CD47 is exercised by macrophages to make a distinction between “self” or “nonself.” Anti-CD47 antibodies block the interaction between macrophage signal regulatory protein-α (SIRPα) and tumor surface CD47. Current focus in immunotherapy has been targeted toward inhibiting CD47-SIRPα interaction via anti-CD47 antibodies. This activates innate immunity, promoting cancer cell destruction by macrophages.

Two exciting companies in the space About Trillium Therapeutics. Trillium is an immuno-oncology company developing innovative therapies for the treatment of cancer. The company’s two clinical programs, TTI-621 and TTI-622, target CD47, a “do not eat” signal that cancer cells frequently use to evade the immune system. Forward Looking Statements Our 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. The CD47 binding domain of ALX148 is an affinity enhanced extracellular domain of signal regulatory protein alpha, or SIRPα, a protein that is the natural receptor to CD47 found on myeloid cells.

The decoy fusion protein approach is differentiated from competitors using monoclonal antibodies raised against About Trillium Therapeutics Trillium is an immuno-oncology company developing innovative therapies for the treatment of cancer. The Company’s two clinical programs, TTI-621 and TTI-622, target CD47, a “do not eat” signal that cancer cells frequently use to evade the immune system. CD47 is a cell surface protein in the immunoglobulin superfamily which is normally expressed at low levels in every healthy cell. It´s main physiologic function is to act as an inhibitor of phagocytosis; this occurs throughout interaction with SIRPa expressed on macrophages. Interaction between CD47 and SIRPa leads to activation of tyrosine phosphatases that inhibit myosin accumulation at the C4T is as differentiated as differentiated gets.

These therapeutics differ in their pharmacodynamic, pharmacokinetic and toxicological properties. 2020-12-07 · CD47 is a protective “don’t eat me” signal that blocks the ability of certain immune cells to destroy the tumor.

Dr. Yaping Shou is the Chief Medical Officer of Trillium Therapeutics, a clinical-stage immune-oncology company developing innate immune checkpoint inhibitors. She has close to 20 years of industry experience spanning clinical development CD47 is overexpressed in numerous hematological cancers and solid tumors, and high CD47 expression correlates with more aggressive disease and poorer clinical outcomes. Preclinical studies have shown that interrupting the CD47-SIRPα signaling pathway promotes anti-tumor activity against human cancers, both in vitro and in vivo.
