Antibody Drug Conjugates


What Are Antibody Drug Conjugates?

Antibody-drug conjugates (ADCs) combine the high specificity of monoclonal antibody drugs with the high activity of small-molecule cytotoxic drugs to improve the targeting of tumor drugs and reduce toxic and side effects. The antibody portion of the ADC binds to proteins on the surface of cancer cells, and the entire complex is then internalized into the cell. Once inside, the drug portion of the ADC is released and kills the cancer cell by disrupting vital cellular processes.

ADCs have several advantages over traditional chemotherapy, including higher specificity and lower toxicity. They are also highly effective at killing cancer cells, making them promising new treatments for many types of cancer.
