Purpose: To test the antitumor activity of Elsamitrucin in metastatic cancer of the breast, colon and rectum, non-small cell lung and ovary.
Patients and methods: Eligibility required histologically proven cancer. Patients with colorectal or non-small cell lung cancer could not have received prior chemotherapy. Patients were entered if WHO PS was < or = 2 and organ functions were normal. 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.
