PURPOSE: A phase II trial was performed to evaluate the efficacy, tolerance, and pharmacokinetic profiles of oral vinorelbine (Navelbine). Oral Navelbine (NVB; Pierre Fabre Médicament, Boulogne, France) was given as first-line chemotherapy for locally advanced or metastatic breast carcinoma (ABC). PATIENTS AND METHODS: Sixty-four patients were entered to receive oral NVB on a weekly basis for a total of 8 weeks unless progression or toxicity occurred. Oral NVB was given at 60 mg/m(2) weekly for the first three administrations and was increased to 80 mg/m(2) for the subsequent administrations if there was no grade 4 neutropenia or no more than one episode of grade 3 neutropenia. Patients with objective response or stable disease continued treatment up to a total of 12 weeks or more. RESULTS: Fifty-eight evaluable patients were included in our study. Four patients (6.9%) had complete responses, and 14 (24.1%) had partial responses, for an overall response rate of 31% (95% CI, 19% to 43%). Median progression-free survival was 17.4 weeks. Median overall survival is not yet reached. There were no treatment-related deaths. The main toxicity was neutropenia: grade 4 in 17.2% of the patients, and 1.8% of administrations and associated clinical serious events in 4 patients (6.2%). Grade 3 and 4 nausea and/or vomiting were noted in 3.1% and 4.6% of the patients, respectively. Only one patient developed grade 3 neuroconstipation. An analysis of Quality of Life Questionnaire C30 forms revealed no significant alteration between baseline and weeks 8 and 16 in global quality of life. CONCLUSION: Oral NVB at this schedule is an effective and well-tolerated agent in the treatment of ABC and offers a promising alternative to the intravenous route. Combination studies are ongoing.
