WebAn ADC for cancer therapy consists of a potent cytotoxic payload that is attached to a tumour-targeted antibody by a chemical linker, usually with an average drug-to-antibody ratio (DAR) of 3.5-4. The theory is to deliver potent cytotoxic payloads directly to tumour cells while sparing healthy cells. WebApr 8, 2024 · While the linkers are similar, ADC1 has a DAR of approximately 2 and composed of a Pyrrolobenzodiazepine (PBD)-based drug, and ADC2 has a DAR of approximately 3 and composed of an auristatin-based drug. For both ADCs, the drug is conjugated through interchain cysteine resides.
WebAntibody-drug conjugates or ADCs are a class of biopharmaceutical drugs designed as a targeted therapy for treating cancer.
