By binding to both of these proteins, this drug brings the cancer cells and immune cells together, which is thought to cause the immune system to attack the cancer cells. The first monoclonal antibodies were made back in 1975 by Csar Milstein and Georges J.F. Sometimes, lab-made monoclonal antibodies are used to treat certain health problems, such as cancer, heart disease, rheumatoid arthritis and more.
