CPT-11 is one of the most widely used camptothecin analogues and is converted to form the active metabolite SN-38. Clinical trials are ongoing to better characterize its spectra of clinical activity, to determine the optimal schedules of administration, and to define the usage in combination with other chemotherapeutic compounds.
