An antibody-drug conjugate (ADC) is comprised of an antibody connected to a cytotoxic agent with a linker. ADCs are designed to selectively target tumors via binding to specific markers found on the cell surface. Although many ADCs are in clinical development, only a few are FDA approved. To improve the efficacy of ADCs in the treatment of cancer, the Seeker is looking for innovative molecular strategies to minimizing off-target toxicities of ADCs.
