Twenty-three patients with advanced heavily pretreated epithelial carcinoma of the ovary were treated with m-AMSA. Eleven patients received a mean of 2.3 courses at a dose of 40 mg/m2 X 3 days q 21 days and 12 patients received a mean of 4.3 courses at a dose of 30 mg/m2 X 3 days q 21 days intravenously. One (5%) partial response in 22 fully evaluable patients was observed. Toxicity was mild and well tolerated. We conclude that m-AMSA is a relatively inactive drug in the treatment of epithelial ovarian carcinoma.
