ADC Approval up to 2023

Published by BroadPharm on October 17, 2023

Antibody-Drug Conjugates (ADCs) are a class of targeted drugs composed of a payload linked to an mAbs (antibody) that is designed to specifically release their payload at a tumor site.

The History of ADC Drugs Development began with the first ADC clinical trial in 1983. As of October, the FDA has approved 15 different ADCs as seen in Table 1.
