BACKGROUND: Anti-CD47 (Hu5F9-G4) is a human monoclonal immunoglobulin G (IgG)4 antibody that is in clinical trials to treat hematologic or solid malignancies. CD47, a glycoprotein expressed on all cells, binds to signal-regulatory protein α on macrophages and regulates phagocytosis. Blocking CD47 is thought to enhance phagocytosis and promote antitumor responses. Here, we evaluate drug interference in pretransfusion testing, determine mitigation strategies, and compare interference with anti-CD38 (Daratumumab)...

REVIEW
Colin P Murphy, Anthony Sanchez, Liam A Peebles, Matthew T Provencher
The decision to incorporate ortho-biologics into a clinical practice will ultimately depend on physicians' preferences and the resources available to their practice. It is important to emphasize that different biologics are used for different pathologies/injuries and in different settings, such as the operating room or in the office. Physicians thinking about using biologics in their practices should consider the time commitment required to learn and use the technique, insurance coverage, and informed consent...
