Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to:

1. To elucidate the mechanism involved in the sorafenib-induced hypophosphatemia and possible early effect of hypophosphatemia on bone mineral density
2. A secondary objective to assess the effect sorafenib treatment on evaluate left ventricular function (LVEF) and Beta-type natriuretic peptide in plasma.

* Histologically or cytologically confirmed advanced RCC
* Evaluable disease with lesions measured by CT-scan or MRI according to modified Response Evaluation Criteria in Solid Tumors (RECIST)
* ECOG Performance Status of 0 or 1
* Adequate bone marrow, liver and renal functions as assessed by the following laboratory requirements to be conducted within 7 days prior to screening:

* Hemoglobin \> 9.0 g/dL 1. Age greater Than 18 yrs old
* Absolute neutrophil count (ANC) \> 1,500/mm3
* Platelet count 100,000/mm3

* Amylase and lipase \< 1.5 x the upper limit of normal
* PT-INR/PTT 1.5 x ULN (Patients who are being prophylactically anti-coagulated with an agent such as coumadin or low molecular weight heparin or therapeutically anti-coagulated with LMWH will be allowed to participate provided that they meet these criteria; in addition, these patients must be monitored at appropriate intervals throughout study)
* Serum creatinine \< 2.0 x the upper limit of normal or creatinine clearance (CrCl) 45 mL/min (CrCl = Wt (kg) (140-age)/72 Cr level, female 0.85) for patients with creatinine levels above 2.0 x ULN
* Phosphate 2.0 mg/dl
* LVEF \>/= 40%
* Women of childbearing potential must have a negative serum pregnancy test performed within 7 days prior to the start of treatment. Negative results must be available prior to study treatment
* Women of childbearing potential and men must agree to use adequate contraception prior to study entry and for the duration of study participation, including the 30 day period after last study drug dosing. The investigator should advise the patient how to achieve adequate contraception
* Signed informed consent must be obtained prior to any study specific procedures

Exclusion Criteria

* Patients who meet the following criteria at the time of screening will be excluded:

* History of cardiac disease: congestive heart failure \>NYHA Class 2; hospitalization for CHF symptoms in the 6 months prior to study entry; active CAD (MI more than 6 months prior to study entry is allowed); cardiac arrhythmias requiring anti-arrhythmic therapy (beta blockers or digoxin are permitted) or uncontrolled hypertension
* Known history of HIV infection or chronic hepatitis B or C
* Uncontrolled hypertension defined as systolic blood pressure \> 150 mmHg or diastolic pressure \> 90 mmHg, despite optimal medical management

* Any condition that is unstable or could jeopardize the safety of the patient and their compliance in the study
* Unable to swallow oral medications
* Any malabsorption condition
* Current treatment with bisphosphonates therapy or prior therapy with such agents within 12 weeks of enrollment
