Antibody-drug conjugates(ADCs) list Approved by FDA(2000-2023)

Antibody-drug conjugates(ADCs) are use specific linkers to connect antibodies and small molecule cytotoxic drugs, and their main components include antibodies, linkers and small molecular cytotoxic drugs. Antibody molecules mainly play the role of targeted delivery, and small molecule drugs play the role of effect. However, some antibodies also have anti-tumor pharmacodynamic effects.

Compared with other chemotherapeutic drugs, ADC drugs greatly improve the specificity of drug administration through the specific combination of antigen and antibody. The antibody binds to the specific antigen on the tumor cell membrane, induces endocytosis, and makes the antibody and the cytotoxicity attached to it The small molecule enters the cell, and then undergoes lysosome degradation. The small molecule drug is released into the cell and induces apoptosis through DNA insertion or inhibition of microtubule synthesis.

Antibody-drug conjugates(ADCs) are an important class of highly potent biopharmaceutical drugs designed as a targeted therapy for the treatment of people with cancer. As the hottest research topic, ADC technology is intended to target and kill only the cancer cells and spare healthy cells. ADCs are complex molecules composed of an antibody linked to a biologically active cytotoxic (anticancer) payload or drug. Antibody-drug conjugates are examples of bioconjugates and immunoconjugates.

It has been more than 100 years since the concept of ADC was proposed, but there are still few varieties on the market and most of the varieties under research are still in the early stage. The main reason is that the development of ADC drugs is difficult and the technical barriers are high. ADC drugs need to go through multiple steps to take effect after entering the body, and each step has technical difficulties that need to be overcome.

As of November 2022, the FDA has approved 13 different ADCs, including Lumoxiti (moxetumomab pasudotox-tdfk), which we consider an immunotoxin.

A stable link between the antibody and the cytotoxic (anti-cancer) agent is a crucial aspect of an ADC conjugation. A highly stable ADC linker will ensure that less of the cytotoxic payload falls off in circulation, driving an improved safety profile, and will also ensure that more of the payload arrives at the cancer cell, driving enhanced efficacy. Linkers are based on chemical motifs including disulfides, hydrazones or peptides (cleavable), or thioethers (noncleavable) and control the distribution and delivery of the cytotoxic agent to the target cell.
