Study to Assess Various Sunitinib Schedules in Renal Cell Carcinoma

Key Inclusion Criteria:

• Men or women over 18 years old
• Patients with local, advanced or inoperable or metastatic (MRCC) renal cell carcinoma who are starting first line treatment with Sunitinib 50mg (4/6 regimen) according to the Marketing Authorisation Indication
• Patients with histologically or cytologically confirmed renal cancer, clear cell variant or with a clear cell component
• Karnofsky performance status ≥ 70%

• Adequate organ function:

  • Absolute neutrophil (N) count ≥ 1 500 / µL
  • Platelets ≥ 100 000 / µL
  • Haemoglobin ≥ 10 g/dL
  • Adjusted serum calcium ≤ 2.6 mmol/L
  • Creatinine clearance ≥ 30 mL/min (by the MDRD formula)
  • Total bilirubin ≤ 1.5 x ULN (upper limit of the normal range)
  • AST ≤ 2.5 x ULN and ALT ≤ 2.5 x ULN OR AST and ALT ≤ 5 x ULN if liver abnormalities due to liver metastases AST = aspartate aminotransferase ALT = alanine aminotransferase

Key Exclusion Criteria:

• Renal carcinoma with no clear cell component.
• Previous systemic treatment for the RCC regardless of type (including targeted therapy, immunotherapy, chemotherapy, hormone or experimental therapy). Previous or concomitant treatment with a bisphosphonate or denosumab is allowed.
• Patients whose clinical state and comorbidities are not consistent with administration of Sunitinib at the initial dose of 50mg/day 4 weeks out of 6.
• Grade 3 haemorrhage within 4 weeks before starting treatment with Sunitinib (according to the NCI-CTCAE toxicity score version 3.0).
• The presence of a past history of cancer in the 3 years before inclusion into the study
• Major surgery within 4 weeks before sunitinib initiation
• Past history of symptomatic cerebral metastases, spinal cord compression or meningeal carcinomatosis. Patients with cerebral metastases discovered incidentally on imaging and who are asymptomatic are not excluded if these metastases have been treated (radiotherapy and/or surgery) with a period of at least 4 weeks between the end of treatment and inclusion into the study and no clinical or radiological signs of relapse, and corticosteroid dose is not exceeding 10mg/day of prednisone or equivalent. Subjects will be excluded if subjects have signs of grade ≥ 2 treatment-related complications.
• Any of the following features within 6 months of the administration of Sunitinib: myocardial infarction, severe/unstable angina, coronary artery/peripheral artery bypass graft, symptomatic congestive heart failure, cerebrovascular accident or transient ischemic attack.
• Pulmonary embolism or deep vein thrombosis within 3 months of inclusion (unless it's stable, asymptomatic and treated with a low molecular weight heparin for at least 6 weeks before inclusion).
• Any known acute or chronic disorder (such as severe chronic obstructive pulmonary disease) which in the opinion of the investigator could impact on the patient's capacity to receive the study treatment or make interpretation of toxicity or adverse events difficult.
• Known HIV infection.
• History of chronic active hepatitis including subjects who are carriers of the hepatitis B (HBV) or hepatitis C (HCV) virus.
• Existence of uncontrolled infection.
• Uncontrolled hypertension defined as a blood pressure of > 150 mmHg systolic or > 100 mmHg diastolic despite optimal anti-hypertensive therapy (blood pressure must be controlled at inclusion).
