Aug. 7—Last year, when then-President Donald Trump tested positive for COVID-19, one of the treatments he used was monoclonal antibodies therapy (mAb). At the time, the therapy was experimental. A monoclonal antibody is a single antibody and sometimes they put them together—what is called a monoclonal antibody cocktail. That's what Trump received. Both convalescent plasma and monoclonal antibodies are what we call antibody-based therapies, but they differ in how they are made Humanized monoclonal antibodies (MoAbs) represent a significant addition to therapeutic armamentarium for a variety of malignancies. Many of the agents that are used for cancer therapy share a risk for infusion reactions, most of which occur with the first dose. Although the majority of reactions are mild and not life threatening, serious.
Most monoclonal antibody biologics readily cross the placenta, 2, 3 leading to concerns regarding their use during pregnancy and their impact on the fetus and infant, and historical avoidance of their use during pregnancy. However, the last decade has seen a shift in disease management toward tight disease control in pregnant patients and a goal of improving both maternal and fetal outcomes The monoclonal antibodies had been safely used in other animal trials before being used in human trials. This is an example of how careful we must be during drug development
Human Monoclonal Antibodies: The monoclonal antibodies produced by using mice are quite suitable for in vitro use. However, their administration to humans is associated with immunological complications, since they are foreign to human body. Production of human monoclonal antibodies is preferred How monoclonal antibodies are made. Monoclonal refers to antibodies that are all of the same isotype and specificity. In other words, monoclonal antibodies are derived from a single B cell clone. One common way of producing monoclonal antibodies is from a hybridoma, a fusion between an antibody-producing B cell and a myeloma cell. Faculty of Pharmaceutical Science, Assam down town University 8 Polyclonal antibodies Monoclonal antibodies Produced by: Many B cell clones A single B cell clone Binds to: Multible epitopes of all antigen used in the immunization A single epitope of a single antigen Antibody class: A mixture of different Ab classes (isotypes) All of a singleAb. Polyclonal antibodies are made using several different immune cells. They will have the affinity for the same antigen but different epitopes, while monoclonal antibodies are made using identical immune cells that are all clones of a specific parent cell (Figure 1). For applications such as therapeutic drug development that require large volumes.
