Genmab provides insights into IgG4 antibodies
This exchange of target-binding arms underlies the anti-inflammatory activity seen with IgG4 antibodies and may lead to a dampening effect on inflammatory reactions in certain conditions such as allergies or autoimmune disease. These dynamic and unstable properties make IgG4 antibodies unpredictable and thus unfavorable for human therapeutic use, in spite of their potential advantage in treating diseases for which effector function is not desired.
These findings will be published in the journal Science. The studies were performed in collaboration with scientists at Sanquin Research, Amsterdam and the University of Maastricht, the Netherlands.
"These insights into the mechanisms of human IgG4 antibodies are what led Genmab to develop the UniBody(TM) technology platform," said Prof. Jan G. J. van de Winkel, Chief Scientific Officer at Genmab. "By removing the hinge region of the IgG4 antibody molecule, we have created a small, stable and inert half-molecule with a long half-life called UniBody which may provide effective treatments for certain types of cancer and autoimmune disease."

Antibodies are specialized molecules of our immune system that can specifically recognize and neutralize pathogens or foreign substances. Antibody research in biotech and pharma has recognized this natural defense potential and is working intensively to make it therapeutically useful. From monoclonal antibodies used against cancer or autoimmune diseases to antibody-drug conjugates that specifically transport drugs to disease cells - the possibilities are enormous
