Phase II study of 3-deazauridine in advanced colorectal adenocarcinoma

A phase II study of 3-deazauridine (DAUR) showed poor activity in previously treated patients with advanced colorectal adenocarcinoma. There were no responses among 15 patients treated on a dose schedule of 1200 mg/m2/day for 5 days repeated at 3-week intervals. Toxicity included mild nausea and vomiting, occasional mucositis, diarrhea, and dizziness. A minimal degree of myelosuppression was observed.
