Irinotecan liposome (Onivyde)
Class/mechanism: Topoisomerase I inhibitor with irinotecan contained within a liposomal sphere. Irinotecan interferes with topoisomerase I's normal action of relieving torsional strain in DNA by creating reversible single-strand breaks. Irinotecan and its active metabolite SN-38 bind to the topoisomerase I & DNA complex and interfere with ligation of these single-strand breaks. Failure to repair these breaks eventually leads to double-strand DNA damage, which disrupts cell proliferation and leads to cell death. In mouse models, 5 times lower doses of liposomal irinotecan were able to achieve similar intratumoral exposure levels of SN-38 as compared to irinotecan HCl.
