Abstract
Purpose: To determine the feasibility, maximal tolerated doses, and response rates for a combined regimen of the platinum and 5-fluorouracil oral analogues bis-acetato-ammine-dichloro-cyclohexyl-amine platinum(IV) (JM-216) and uracil/ftorafur (UFT) coadministered as a 14 consecutive-day every 28- day schedule. Methods: Of 20 patients enrolled in this investigation, 17 on the following dose escalation scheme were evaluable for toxicity and/or response: I UFT 300 mg/day, JM-216 5 mg/day (three patients), II UFT 300 mg/day, JM-216 10 mg/day (four patients), III UFT 300 mg/day, JM-216 20 mg/day (ten patients). Results: All 17 evaluable patients were evaluable for toxicity. At dose level III, dose-limiting nausea and emesis were observed in one patient despite maximal antiemetic support. Importantly, neurotoxicity and nephrotoxicity were not observed at the JM-216 dose levels examined in this study. This observation is consistent with results seen with single agent JM-216. Conclusion: For JM-216 and UFT administered at 20 mg/day and 300 mg/day over 14 days, nausea and emesis were observed as the principal dose-limiting toxicities. These doses are considerably below the maximally tolerated doses of single agent JM-216 and UFT. Shorter administration schedules should be explored in an attempt to increase the dose intensity and minimize the toxicity of this combination oral regimen.
