About

The principal aim of the study is to determine the objective response rate that offers the second-line treatment with pazopanib in patients with carcinoma of advanced renal cells that have progressed or that have not tolerated the first line of treatment with a Tyrosine Kinase Inhibitor. The secondary aims are to determine the overall survival and the treatment safety profile for these patients in second-line treatment with pazopanib. The exploratory aim is to determine the correlation between biomarkers in patient blood and tumor samples, and the clinical results obtained with pazopanib.

Full description

Patients who progress or do not tolerate a first-line treatment with a Tyrosine Kinase Inhibitor will be included consecutively in the study. All patients will receive the same treatment regimen consisting of 800 mg / day of pazopanib in monotherapy.

All patients will receive treatment until there is evidence of progression, evidence of unacceptable toxicity, not compliance, investigator clinical decision or consent withdrawal by the patient.

After treatment, the patient will enter to the follow-up period. During this period the investigator will collect information from subsequent administered treatments and survival of all patients, regardless of the reason for withdrawal, every 8 weeks until the scheduled end of follow-up period, according to protocol. At 30 days after treatment completion, the first follow up visit will be scheduled to assess the possible occurrence of late toxicity. In those patients who complete treatment prior to objectify progression, information about the progression of the disease will be collected.

Inclusion criteria

Signed Inform Consent
Age ≥ 18
Histologically confirmed diagnosis of clear cell renal carcinoma metastatic or locally recurrent unresectable.
Patients must have received only a first-line treatment with a Tyrosine Kinase Inhibitor. Patients must have progressed during treatment or within three months after stopping treatment with these agents. Patients who discontinued treatment with a Tyrosine Kinase Inhibitor for unacceptable toxicity are also eligible for the study.
Patients must have been previously treated by nephrectomy with removal of the primary tumor, except that there is a contraindication (eg liver I extensive bone metastatic disease or primary tumor smaller than 5 cm).
Patients with ECOG PS 0 or 1.
To be included in the study, the renal tumor should be classified in a group of low or intermediate risk according to the Motzer classification.
Eligibility criteria under RECIST v.1.1
Adequate hematologic function:

Absolute neutrophil count ≥ 1.5 x 109 / L Platelet count ≥ 100 x 109 / L Hemoglobin ≥ 9 g / dL (5.6 mmol / L). Prothrombin time (PT) or international normalized ratio (INR) ≤ 1.2 X ULN. Activated partial thromboplastin time (APTT) ≤ 1.2 X ULN
Adequate hepatic function:

total bilirubin ≤ 1.5 X ULN ALT ≤ 2.5 x ULN
Adequate renal function:

Serum creatinine ≤ or 1.5 mg / dL (133 mol / L). If> 1.5 mg / dL, then the calculated creatinine clearance has to be ≥ 50 mL / min (Appendix 1).

Urine protein / creatinine ratio <1.
Can be included in the study of both fertile and infertile women.

Exclusion criteria

Previous malignancy. May be included in the study patients with a disease-free interval of 5 years at the time of inclusion in the study and patients with non-melanoma skin carcinoma completely resected or carcinoma in situ treated successfully.
Previous treatment with more then one Tyrosine Kinase Inhibitor or more than one previous traditional regime (eg, chemotherapy, immunotherapy or chemo-immunotherapy).
Known history or clinical evidence of nervous system metastases or leptomeningeal carcinomatosis, except that metastases in the central nervous system have been previously treated, are asymptomatic and not requiring treatment with corticosteroids or anticonvulsant medication within six months before the first administration of pazopanib.
Clinically significant gastrointestinal disorders that may increase the risk of bleeding gastrointestinal.
Clinically significant gastrointestinal disorders which may affect the absorption of pazopanib.
Presence of uncontrolled infection.
ECG QT interval longer than 480 milliseconds, according to the Bazett formula.
History of one or more of the following cardiovascular conditions within the last 6 months prior to inclusion:

Cardiac angioplasty or stent placement Myocardial infarction Unstable angina Surgery or coronary bypass Symptomatic peripheral vascular disease

Treatment with any of the following antineoplastic therapy: radiation therapy, surgery, tumor embolization, chemotherapy, immunotherapy, biologic therapies, investigational therapies or hormone treatments within 14 days, or the time equivalent to 5 half-lives (whichever is greater), to the administration of the first dose of pazopanib.
Any unresolved toxicity from previous cancer therapies> Grade 1 and / or is getting worse in intensity, except for alopecia.
