Study Overview
=================
Brief Summary
-----------------
Multi-center, prospective randomised phase III study evaluating capecitabine in combination with standard-immunotherapy versus standard-immunotherapy alone as first-line therapy in patients with metastatic renal cell carcinoma.

Detailed Description
-----------------
Treatment plan Group A Patients randomised to group A will receive treatment according to the following treatment schedule: Group A: Combined Chemo-Immunotherapy Chemotherapy: Mo-Fr Immunotherapy Week 1:Capecitabine / Interferon; Week 2:Capecitabine / Interferon; Week 3:REST PERIOD / Interleukin; Week 4:Capecitabine / Interleukin; Week 5:Capecitabine / REST PERIOD; Week 6:REST PERIOD / Interferon; Week 7:Capecitabine / Interferon; Week 8:Capecitabine / Interleukin; Week 9:REST PERIOD / Interleukin; Week 10:Capecitabine / REST PERIOD; Week 11:Capecitabine / Interferon; Week 12:REST PERIOD / Interferon; Week 13:Capecitabine / Interleukin; Week 14:Capecitabine / Interleukin; DOSAGES AND ROUTES OF ADMINISTRATION: Capecitabine orally from day 1 to 14 at a dose of 1000 mg/m2 twice daily every 21 days. Interferon-alpha subcutaneously on days 1 + 3 + 5 weeks 1 + 2 +6 + 7,11+12 at a dose of 6 MIU/d. Interleukin-2 subcutaneously on days 1 to 4 in weeks 3 + 4 +8 + 9,13+14 at a dose of 4.5 MIU/day. Group B Patients randomized to group B will receive treatment according to the same treatment schedule and at the same dosages without capecitabine. Efficacy evaluations will be performed every 14 weeks of treatment in both groups
