Sixteen patients with metastatic melanoma were treated with N-methylformamide (NMF), a polar-planar compound with in vitro cytotoxic and differentiating properties. Sixteen patients were evaluable for toxicity and 14 for response. The initial four patients received an intravenous bolus of NMF 800 mg/m2 daily for 5 consecutive days every 28 days. Because of excessive gastrointestinal toxicity, the dose was reduced to 700 mg/m2/day for the subsequent 12 patients. Two patients had immediate adverse effects from NMF; one had a grand mal seizure and the other developed severe abdominal pain. Nausea, vomiting and abdominal pain were dose-limiting. Transient elevation of liver function tests occurred in all patients. Myelosuppression was not observed. There were no objective responses among 14 evaluable patients (95% confidence limits 0-20%). One patient with pulmonary metastases had a minor response lasting 13 months. Median time to progression of disease was one month. NMF in these doses and schedule lacks clinical efficacy in the treatment of metastatic melanoma.

Forty-four patients with advanced, measurable, epithelial carcinoma of the ovary were treated with 97 courses of N-methylformamide (N-MF) at doses ranging from 600-800 mg/m2, intravenously, daily for 5 days every 28 days. Forty-one patients had prior surgery and had received one prior chemotherapy regimen. Only seven patients had received any prior radiation therapy. All patients were Gynecologic Oncology Group (GOG) performance status 0, 1, or 2. Three partial responses were seen. Hematologic adverse effects were extremely rare as predicted by early clinical trials. One major toxicity was a syndrome consisting of some combination of myalgias, arthralgias, pleuritic pain, abdominal pain, peripheral neuropathy, anorexia, lethargy, and declining performance status (pain-lethargy syndrome) that was reversible with discontinuation of the drug. This adverse effect was as common a reason as hepatic toxicity for discontinuation of N-MF. As reported in previous studies with this drug, hepatic toxicity was also common, usually reversible, and also a cause for discontinuation of the drug. The low level of clinical activity and the unpleasant adverse effects in this population of patients with previously treated ovarian cancer makes it unlikely that this drug will play any significant role in treatment of epithelial ovarian cancer.

Three National Cancer Institute of Canada phase II studies of N-methylformamide (NMF), given in a three times/week oral schedule, closed early because of frequent and occasionally severe toxicity. Eighteen of 41 (44%) cycles of treatment were not completed because of problems with NMF-induced hepatic and gastrointestinal toxicity. Several other reactions occurred, including skin rashes, abdominal pain, and gastritis, which were drug induced. One death occurred on study and was thought to be due in part to NMF toxicity. Further work exploring alternative schedules is needed before phase II studies of oral NMF can be done.
