Allocation: RANDOMIZED | Intervention model: SINGLE_GROUP
Enrollment: 12
Healthy volunteers: no

Brief summary:
The primary objective of this study is to compare the effectiveness of a dose-escalation regimen (400 to 800mg bid) relative to the standard dosing regimen (400mg bid) of sorafenib given in patients with metastatic RCC.

The secondary objectives are to evaluate the effects of the dose-escalation regimen on the quality of life (QoL) of patients with metastatic RCC and to characterize the safety and tolerability profile of a dose-escalation regimen of sorafenib in patients with metastatic RCC.

Detailed description:

Arms:
arm 1: Eligible patients will be randomized 2:1 to either Group A (escalated dose regimen) or Group B (standard dose regimen). Patients randomized to Group A will receive sorafenib 600 mg bid for Weeks 5 through 8 (Dose Level 2). Patients who tolerate this dose through Week 8 will be further escalated to Dose Level 3 (800 mg po bid) for Weeks 9 through 12. arm 2: Eligible patients will be randomized 2:1 to either Group A (escalated dose regimen) or Group B (standard dose regimen). Patients randomized to Group B will receive Dose Level 1 (sorafenib 400 mg po bid) until progression of disease, intolerable toxicity, patient refusal to continue with the study, or investigator decision to remove the patient from the study.

Interventions: intervention 1: Sorafenib Escalated Dose intervention 2: Sorafenib Standard Dose
