• Planned resection of primary tumor
• Primary tumor diameter ≥40 mm
• Candidate for first-line therapy with sunitinib initiated 5-8 weeks after nephrectomy
• Female or male ≥18 years of age
• Willing and able to provide informed consent
• Adequate hematological parameters, i.e:
• B-Leukocyte count ≥4.5 x10e9/L
• B-Platelet count ≥150 x10e9/L
• B-Hemoglobin ≥90 g/L
• S-creatinine and S-bilirubin ≤ 1.5 x upper limit of normal (ULN). Serum alanine aminotransferase (S-ALAT) and serum aspartate aminotransferase (S-ASAT) ≤ 2.5 x ULN (or ≤5 in case of liver metastases)
• Female who has been post-menopausal for more than one (1) year or female of childbearing potential agreeing to use a highly efficient method of contraception (i.e. a method with less than 1% failure rate [e.g. sterilization, hormone implants, hormone injections, some intrauterine devices, or vasectomized partner or combined birth control pills]) Female of childbearing potential must have a negative from Screening until 90 days after last dose of Intuvax and/or until completed sunitinib treatment whichever occurs later.blood pregnancy test at Screening, and if randomized to vaccination a negative blood or urine pregnancy test within one (1) day before each dose of Intuvax) and must not be lactating. or Male agreeing to use condoms from Screening until 90 days after last dose of Intuvax and/or until completed sunitinib treatment whichever occurs later, or male having a female partner who is using a highly efficient method of contraception as described above.

Exclusion Criteria

• Life expectancy less than 4 months
• Central nervous system (CNS) metastasis that is symptomatic or progressing or untreated or that required current therapy (e.g. evidence of new or enlarging CNS metastasis or new neurological symptoms attributable to CNS metastases)
• Active autoimmune disease which requires treatment with systemic immunosuppressive agents, e.g. inflammatory bowel disease, multiple sclerosis, sarcoidosis, psoriasis, autoimmune hemolytic anemia, rheumatoid arthritis, systemic lupus erythematosus (SLE), vasculitis, Sjögren's syndrome, scleroderma, autoimmune hepatitis, and other rheumatological diseases
• Treatment with per oral systemic corticosteroids exceeding 10mg/day within seven (7) days before Screening until nephrectomy (inhaled, intranasal and local steroids accepted irrespective of dose)
• Known cardiomyopathy and/or clinical significant abnormal ECG findings at Screening disqualifying the patient from nephrectomy and from subsequent sunitinib treatment
• Karnofsky performance status <70%
• National Cancer Institute (NCI) Common Terminology criteria for Adverse Events (CTCAE) Grade 3 hemorrhage within 28 days before Screening
• Pre-existing thyroid abnormality with thyroid function that cannot be maintained in the normal range with medication
• Clinically significant gastrointestinal abnormalities
• Uncontrolled hypertension, or uncontrolled diabetes mellitus
• Pulmonary embolism within 12 months before screening
• Prior history of invasive cancer within 5 years before screening, except for adequately treated in situ carcinomas or non-melanoma skin cancer
• Ongoing infection that requires parenteral treatment with antibiotics
• Active or latent virus disease (HIV, hepatitis B and hepatitis C)
• Eastern Cooperative Oncology Group (ECOG) performance status >2 after optimization of analgesics
• Abnormal and clinical significant coagulation parameters at the discretion of the Investigator, i.e.:
• Prothrombin Time - International Normalized Ratio (PT-INR)
• Activated Partial Thromboplastin Time (APTT) patients being treated with anticoagulants are excluded if the coagulation parameters are outside the therapeutic intervals as described in the summary of product characteristics (SmPC) / United States prescribing information (USPI) for the administered treatment
• Known major adverse reaction/event in connection with previously made vaccination (e.g. asthma, anaphylaxis or other serious reaction)
• Known hypersensitivity or allergy sunitinib or to chemically related products or likely to be exacerbated to by any component of the study products
• Prior systemic antitumour therapy within 28 days before Screening Visit. However, local radiation therapy to any area except for the abdominal/retroperitoneal area including the kidney tumour is allowed
• Exposure to other investigational products within 28 days prior to Screening Visit
• patients on anticoagulants for whom temporarily stop and start, supported by low molecular weight heparin (or other anticoagulation therapy at the discretion of the investigator and or per local standard of care) during vaccination and nephrectomy, is not an option
• History of alcohol or substance abuse
• Any reason that, in the opinion of the Investigator, contraindicates that the patient participates in the study
