Recruitment & Eligibility

• Status: ot Recruiting
• Sex: All
• Target Recruitment: 88

Inclusion Criteria

- Written informed consent
- Age = 18 and = 80 years
- ECOG Performance Status: 0-1-2
- Life expectancy =24 weeks
- Diagnosis of predominantly clear cell RCC
- Risk score (Heng criteria): favorable or intermediate
- No previous systemic treatment for Renal Cell Carcinoma
- Documented metastatic disease (CT scan or MRI) with at least two bone metastasis (non pretreated with radiotherapy). Lesions could be measurable or not according with RECIST criteria v.1.1.
-Laboratory requirements: Neutrophils =1.5 x 109/L, Platelets =100 x 109/L, and Haemoglobin =10g/dL; Total bilirubin =1.5 time the upper-normal limits (UNL) of the Institutional normal values except for patients affected by Gilbert’s syndrome; AST (SGOT) and/or ALT (SGPT) =2.5 x UNL, or =5 x UNL in case of liver metastases; alkaline phosphatase =2.5 x UNL, =5 x UNL in case of liver metastases, =10 x UNL in case of bone metastases
- Patients should be compliant to study protocol procedures
- Patients could receive a bone targeted agents after the first two cycles of Pazopanib treatment; the preferred drug is denosumab (due to best renal safety)
- Patients that will receive bone targeted agents must have baseline dental scan and dental examination (and after every 6 months)
- Patients of childbearing age should use contraceptive methods during the study

- Planned radiation therapy or surgery to bone must be before 2 weeks to study enrollment
- Radiotherapy during the study (except palliative radiotherapy)

Primary Outcome Measures

Name	Time	Method
Main Objective: To evaluate the efficacy of first line therapy with Pazopanib, in terms of progression free survival (PFS), in patients with metastatic renal cell carcinoma with bone involvement;Secondary Objective: To assess the safety and tolerability of the first line treatment with Pazopanib. To evaluate pain and quality of life of patients, by means of specific questionnaries. Exploratory objectives: to study the effect of Pazopanib on bone turnover markers;Primary end point(s): Progression free survival (PFS);Timepoint(s) of evaluation of this end point: From the start of the first line treatment with Pazopanib until disease progression or death from any cause
