There are several types of therapeutic antibodies, including: - Monoclonal Antibodies (mAbs): These are antibodies that are identical and target a single antigen. They are highly specific and commonly used in cancer therapy. - Bispecific Antibodies: These are engineered to bind to two different antigens simultaneously, offering a more targeted approach. - Antibody-Drug Conjugates (ADCs): These are antibodies linked to cytotoxic drugs, delivering the drug directly to cancer cells. - Humanized and Fully Human Antibodies: These are antibodies that have been modified to reduce immunogenicity and improve compatibility with the human immune system.
