Background:

MC-SN38 is a drug-linker conjugate composed of a potent microtubule-disrupting agent SN38 and a non-cleavable MC linker to make antibody drug conjugate (ADC). SN-38, an active metabolite of the Topoisomerase I inhibitor Irinotecan, inhibits DNA synthesis and causes frequent DNA single-strand breaks[1][2].
