Genmab was founded by a team of experienced biotechnology professionals, including Dr. Jørgen K. Skou, Dr. Claus Møldrup, and Dr. Henrik G. Birkelund. The company's early focus was on developing therapeutic antibodies using its proprietary technology platform, known as the "DuoBody" format. This platform allows for the creation of bispecific antibodies that can target two different antigens on the surface of cancer cells.
