Healthy volunteers: no

Brief summary:
The purpose of the study is to:

* Find out if patients receiving BAY43-9006 will live longer without tumor progression than those receiving standard therapy with interferon alpha-2a
* Find out if a higher dose of BAY43-9006 can inhibit tumor progression in patients who progressed during standard dose treatment with BAY43-9006, and for how long these patients live without progression
* Find out how long patients live without progression who receive BAY43-9006 after failing to respond to standard therapy with interferon alpha-2a
* Find out in how many percent of patients BAY43-9006 prevents the growth of or shrinks kidney tumors and/or their metastases depending on treatment and dosage
* Find out if BAY43-9006 has any effect on the quality of life of patients with kidney cancer
* Find out the level of BAY43-9006 in the blood once per month and any changes in this level
* Find out whether BAY43-9006 effects are associated with specific biomarkers

Detailed description:
Analyses on Biomarkers were exploratory and assessed as tertiary objective of the trial.

Arms:
arm 1: Subjects received 2 tablets of Sorafenib (200 mg tablets) twice daily (bid) (ie 12-hourly) orally until progression (= first intervention period, 5.7 months \[median\] ) and 3 tablets of Sorafenib twice daily (ie 12-hourly) orally until the following progression (= second intervention period, 3.6 months \[median\]) on a continuous basis. arm 2: Interferon (IFN) α-2a was administered at a dose of 9 million international units(MIU) subcutaneously three times a week until progression (= first intervention period, 5.6 months \[median\]). Subjects initially started with a single dose of 3 MIU IFN and increased the dose as rapidly as possible to 9 MIU IFN three times a week within 1 or 2 weeks in first intervention period.After first progression, subjects received 2 tablets of Sorafenib (200 mg tablets) twice daily (BID) (ie 12-hourly) until the next progression (=second intervention period, 5.3 months \[median\]).

Interventions: intervention 1: Sorafenib (Nexavar, BAY43-9006) intervention 2: Interferon
Intervention descriptions: intervention 1: Multi kinase inhibitor intervention 2: Interferon
