Menogaril in the treatment of malignant mesothelioma: a phase II study

Abstract

Menogaril is a new semisynthetic anthracycline agent derived from the antitumor antibiotic Nogalomycin. Compared to doxorubicin it has similar or improved activity in anti-tumor cell line screening; human tumor cloning assays suggest modest anti-tumor activity as well. Menogaril is much less cardiotoxic than doxorubicin. We performed a phase II trial of this agent in 22 patients with advanced malignant mesothelioma. At a dose of 200 mg/m2 iv every 4 weeks (160 mg/m2 in previously radiated patients) only 1 of 22 (5%) evaluable patients had a partial remission lasting 4 months. (95% confidence limits 0.1-23%). The major toxic effects included pain at the site of infusion and granulocytopenia. While well tolerated, Menogaril has minimal activity in malignant mesothelioma. We do not plan further studies with Menogaril in this disease.
