Abstract | BACKGROUND: Several trials demonstrated efficacy of the gemcitabine/ treosulfan (GeT) combination in metastatic uveal melamoma. This randomized phase II trial compared the GeT combination versus treosulfan alone (T) in this rare disease. PATIENTS AND METHODS:
Chemotherapy-naive patients with proven metastatic uveal melanoma were randomly assigned to receive 1000 mg/m(2) of gemcitabine plus 3500 mg/m(2) of treosulfan (GeT) or 3500 mg/m(2) of T. Chemotherapy was administered on days 1 and 8 in both arms, cycles were repeated on day 29. Primary end point was rate of responses and disease stabilizations. RESULTS: Forty-eight patients were randomized. Seven confirmed stable diseases (SDs) and one partial remission (PR) were observed in 24 patients treated with the GeT regimen, whereas no PR and only three SDs were observed in the T arm (P = 0.08). Median progression-free survival (PFS) was 3 months (95% CI 1.1-4.9) and 2 months (95% CI 1.7-2.3) in the GeT and T arm (P = 0.008, log-rank). Six and 12 months PFS was 34.8% and 17.9% and 16.7% and 0% always favoring the GeT arm. CONCLUSIONS: This first randomized trial in metastatic uveal melanoma showed a superior PFS and a trend for a higher response/stabilization rate of the GeT combination over T.
