TOPOTECAN HYDROCHLORIDE (topotecan) by Pfizer is single-strand breaks. First approved in 2011.
Drug data last refreshed 21h ago · AI intelligence enriched 1w ago
AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
Topotecan is a small-molecule topoisomerase I inhibitor that binds to the topoisomerase I-DNA complex and prevents re-ligation of single-strand DNA breaks. It is indicated for various cancers including ovarian cancer, small cell lung cancer, and cervical cancer. The drug's cytotoxicity results from double-strand DNA damage during replication that mammalian cells cannot efficiently repair.
LOE Approaching
Approaching loss of exclusivity with moderate competitive pressure (30/100) suggests team consolidation and focus shifting toward life-cycle extension or related programs.
Mechanism of Action
single-strand breaks. Topotecan binds to the topoisomerase I-DNA complex and prevents re-ligation of these single-strand breaks. The cytotoxicity of topotecan is thought to be due to double-strand DNA damage produced during DNA synthesis, when replication enzymes interact with the ternary complex…
