Background: The purpose of this study was to determine the dose-limiting toxicity (DLT) and maximum tolerated dose of a combination of vinorelbine plus gemcitabine administered on a biweekly schedule in patients with advanced solid tumors. Patients and methods: Patients with advanced or refractory solid tumors included in this phase I study were treated with vinorelbine followed by gemcitabine. Vinorelbine was given intravenously over 10 min, and gemcitabine was given intravenously at an fixed-dose infusion rate of 10 mg/m(2)/min. Six dose levels of vinorelbine/gemcitabine were explored: 20/2000, 25/2500, 25/3000, 30/3000, 30/3500 and 30/2500 mg/m(2). Results: Nineteen patients were included in the study. Fourteen patients were pretreated with chemotherapy and/or radiotherapy. A total of 123 cycles of chemotherapy were administered. DLTs were neutropenic fever and grade 3 asthenia at dose level 5 (30/3500 mg/m(2)); at dose level 4 (30/3000 mg/m(2)) they were grade 3 asthenia, and a radiation-recall reaction and pneumonitis. Sixteen patients were evaluable for efficacy. Five patients had an objective response (one complete response and four partial responses), for an overall response rate of 31%. Conclusions: The recommended dose for phase II study is vinorelbine 30 mg/m(2) and gemcitabine 2500 mg/m(2) administered once every 2 weeks. This regimen is feasible and well-tolerated at this dose, and shows a good clinical activity in all levels explored.
