Description: Elsamitrucin is a heterocyclic antineoplastic antibiotic isolated from the bacterium Actinomycete strain J907-21. Elsamitrucin intercalates into DNA at guanine-cytosine (G-C)-rich sequences and inhibits topoisomerase I and II, resulting in single-strand breaks and inhibition of DNA replication. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).

In a phase II trial, : Elsamitrucin showed modest activity in patients with relapsed or refractory non-Hodgkin's lymphoma. Toxicity was relatively mild, consisted mainly of asthenia, nausea and vomiting and did not include myelosuppression. The activity of elsamitrucin in this group of patients and its lack of myelosuppression suggest utility in this disease especially when combined with other proven agents. see http://www.ncbi.nlm.nih.gov/pubmed/8913843.
In another phase II trial to test the antitumor activity of Elsamitrucin in metastatic cancer of the breast, colon and rectum, non-small cell lung and ovary. Patients with colorectal or non-small cell lung cancer could not have received prior chemotherapy. Treatment consisted of Elsamitrucin 25 mg/m2/week given as a 5-10 min infusion for at least 3-6 weekly doses. RESULTS: One hundred and five patients entered the studies, 97 were eligible, 94 are evaluable for toxicity and 75 for response. Toxicity mainly consisted of mild nausea/vomiting, and less frequently reversible hepatotoxicity and malaise. No objective responses were seen. CONCLUSION: Elsamitrucin at this dose and schedule is not an active drug in metastatic breast cancer, colorectal cancer, non-small cell lung cancer or ovarian cancer. see http://www.ncbi.nlm.nih.gov/pubmed/8075039.
