MedKoo CAT#: 201410

CAS#: 292618-32-7

Description: Gimatecan is an orally bioavailable, semi-synthetic lipophilic analogue of camptothecin, a quinoline alkaloid extracted from the Asian tree Camptotheca acuminate, with potential antineoplastic and antiangiogenic activities. Gimatecan binds to and inhibits the activity of topoisomerase I, stabilizing the cleavable complex of topoisomerase I-DNA, which inhibits the religation of single-stranded DNA breaks generated by topoisomerase I; lethal double-stranded DNA breaks occur when the topoisomerase I-DNA complex is encountered by the DNA replication machinery, DNA replication is disrupted, and the tumor cell undergoes apoptosis. Although the mechanism of its antiangiogenic activity has yet to be full elucidated, this agent may inhibit endothelial cell migration, tumor neovascularization, and the expression of proangiogenic basic fibroblast growth factor (bFGF). Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).

Additional Information

Phase II study of Gimatecan: From June 2005 to December 2005, 69 assessable patients were enrolled. The best overall response to study treatment by combined CA-125 and RECIST criteria was partial response in 17 patients (24.6%) and disease stabilization in 22 patients (31.9%). The median time to progression and overall survival were 3.8 and 16.2 months, respectively. A total of 312 cycles were administered. Neutropenia grade 4 and thrombocytopenia grade 4 occurred in 17.4% and 7.2% of patients, respectively. Diarrhea grade 4 was never observed. Asthenia and fatigue were reported by 36.2% and 18.8% of patients, but were all grade 2 or less. CONCLUSION: Gimatecan is a new active agent in previously treated ovarian cancer with myelosuppression as main toxicity.   (source: Ann Oncol. 2010 Apr;21(4):759-65.).
