Mechanism of action

MM-398 (nal-IRI) encapsulates irinotecan in lipid nanoparticles that preferentially accumulate in tumors through passive targeting. This allows higher drug concentrations at the tumor site while reducing exposure to normal tissues, thereby improving the therapeutic index of irinotecan. The active metabolite SN-38 inhibits topoisomerase I, leading to DNA damage and cancer cell death.
