Evaluation of Predictive Markers for Toxicity and Efficacy in Patients With mccRCC Treated by Anti-VEGF Therapy

A Proof of Concept Study to Evaluate the Use of Metabonomics and Lipidomics in Predicting Toxicity and Efficacy of Anti-VEGF Therapy in Patients With Metastatic Clear Cell Renal Cell Carcinoma

The purpose of this study is to assess whether certain metabonomics and/or lipidomics features in correlation with pharmacokinetics before, during and after treatment with sunitinib or pazopanib in first line can predict toxicity and efficacy of sunitinib or pazopanib in metastatic clear cell renal cell carcinoma patients.

Inclusion Criteria:

• Woman or man ≥ 18 Years old, histologically proven metastatic clear cell (or al least clear cell predominant) RCC,
• Good or intermediate risk according to MSKCC-criteria, Subjects falling into conditions for reimbursement of sunitinib or pazopanib in the context of mRCC,
• Measurable disease based on RECIST criteria (version 1.1) , Subject has given voluntary written informed consent,
• Subject is in the investigator's opinion, willing and able to comply with the protocol requirements, Subject has an ECOG ≤ 2,
• Subject with a life expectancy ≥ 3 months,
• Concurrent treatment with bisphosphonates and denosumab is allowed however it should have been started before screening of the study. If possible starting new medications between the baseline metabolo- and lipidomotype- and the first metabolo- and lipidomotypeanalysis should be avoided,
• Subjects having recovered from side effects from previous therapies to a grade 1 CTC vs 4.0 criteria

Exclusion Criteria:

• Patients with non-clear cell RCC and/or with sarcomatoid differentiation,
• Patients presenting any other type of cancer disease within 5 years from inclusion into this study; in the absence of cervical cancer or basocellular carcinoma, Patients with uncontrolled arterial hypertension,
• Patients with uncontrolled hypo- or hyperthyroidism,
• Patient had major surgery within 4 weeks before enrolment,
• Patient with myocardial infarction within 6 months prior enrolment or with NHYA class III otr IV heart failure, uncontrolled angina, severe uncontrolled ventricular arrhythmia or electrocardiographic evidence of acute ischemia or active conduction system abnormalities,
• Patient has another serious medical condition that could potentially interfere with the completion of study,
• Sero-positive for HIV, Subject known to be hepatitis B surface antigen positive or who has an active hepatitis C infection,
• Subject has an active systemic infection requiring treatment,
• Female subject is pregnant or breast feeding, Subject enrolled in another clinical trial and/or receiving an investigational agent.
