Multicenter Study Clinical Trial Controlled Clinical Trial
A phase I and pharmacokinetic study of melphalan using a 24-hour continuous infusion in patients with advanced malignancies.
The objectives of the present study were to determine the following: (a) the maximum tolerated dose (MTD) of melphalan using a 24-h continuous infusion; (b) the clinical toxicity; and (c) the pharmacokinetic characteristics of melphalan at each dose level. Twenty-one patients with refractory solid tumors were enrolled in the study. Melphalan, packaged in 3% sodium chloride, was administered i.v. over a 24-h period. ⋯ Hematological toxicity was the dose-limiting toxicity. The most important nonhematological toxicity encountered was nausea and vomiting. The recommended dose for Phase II studies was 30 mg/m2.

Multicenter Study Clinical Trial
A phase I and pharmacokinetic study of docetaxel administered in combination with continuous intravenous infusion of 5-fluorouracil in patients with advanced solid tumors.
Encouraged by preclinical synergism between docetaxel and 5-fluorouracil (5FU), we conducted a Phase I study of docetaxel in combination with continuous i.v. infusion of 5FU in patients with advanced solid tumors to determine the maximum tolerated dose, the recommended dose for Phase II studies, and the safety and pharmacokinetic profiles of this combination. Forty-two patients with advanced solid tumors, most of whom had been previously treated, received docetaxel on day 1 as a 1-h i.v. infusion, immediately followed by a 5-day continuous i.v. infusion of 5FU, every 3 weeks without hematopoietic growth factor support. All patients were premedicated with methylprednisolone. ⋯ Pharmacokinetic results of both drugs were consistent with those from single-agent studies. The recommended dose of this combination, which showed acceptable toxicity and antitumoral activity at various dose levels, is 85 mg/m2 docetaxel given as a 1-h i.v. infusion on day 1 immediately followed by a 5-day continuous i.v. infusion of 5FU (750 mg/m2/day). This study has been extended by adding cisplatin on day 1 of the combination of docetaxel and 5FU.
