Phase II study of vinflunine in patients with metastatic renal cell carcinoma.
OBJECTIVE
An open-label, multicentre, non-comparative phase II trial to determine the response rate of intravenous vinflunine as first line chemotherapy in patients with metastatic renal cell carcinoma (RCC).


METHODS
Patients with metastatic RCC were treated with vinflunine 350 mg/m2 (n = 11) or 320 mg/m2 (n = 22) administered intravenously every 21 days.


RESULTS
Out of 33 patients included in this study, one partial response was observed in the group treated at 350 mg/m2 and none in the group receiving 320 mg/m2 resulting in a response rate in this population of 9.1% (95% CI: 0.2-41.3). Median progression free survival was 5.6 months (95% CI: 2.8-14.4) for patients treated at 350 mg/m2, and 3.3 months (95% CI: 1.6-6.4) for those treated at 320 mg/m2.The median survival time was 10.4 months (95% CI: 6.8-12.4) for the whole study population. The principal toxicities were grade 3/4 neutropaenia -90.9% at 350 mg/m2 and 68.1% at 320 mg/m2, febrile neutropaenia was recorded in 3 patients (27.3%) at 350 mg/m2 and in 5 patients (22.7%) at 320 mg/m2. One episode of thromboembolic event was reported in 1 patient at each dose level.


CONCLUSIONS
Vinflunine given intravenously once every 3 weeks has not shown any clinically relevant activity in the management of patients with metastatic renal cell carcinoma; tolerance of the treatment was better at a dose of 320 mg/m2 than at 350 mg/m2.
