Brief Summary

Positron emission tomography (PET) is a non-invasive imaging tool for monitoring functional and metabolic responses of biological events with specific radiotracer in vivo. The PET tracer [18F]Fluciclatide is an 18F radiolabeled small peptide containing the RGD (arginine-glycine-aspartate) tri-peptide, which preferentially binds with high affinity to αvβ3 and αvβ5 integrins. αvβ3-integrins are expressed at low levels on epithelial cells and mature endothelial cells but are expressed at high levels on activated endothelial cells in the neo-vasculature of a range of tumors and it also may regulate angiogenesis. If pazopanib acts mainly on active angiogenetic tumors, the quantitative uptake of [18F]Fluciclatide can be used to predict the effect of this antiangiogenic drug. The investigators expected the baseline tumor uptake in [18F]Fluciclatide to be able to predict treatment response, and planned a study of [18F]FluciclatidePET for patients with metastatic RCC who received pazopanib systemic therapy.

Detailed Description

Subjects will receive treatment with pazopanib at a dose of 800 mg orally once daily. [18F]Fluciclatide imagings will be taken 2 times; 1) before systemic therapy (at baseline), 2) at one week after starting of Pazopanib. However, If the target lesion on the baseline PET cannot be discriminated compared to the background activity, the 2nd PET will not be done. Response evaluation by CT will be performed at baseline, at 6 week, at 12 week and every 8 weeks thereafter until the end of treatment. RECIST1.1 criteria for response will be applied. Patient will be treated with Pazopanib until there is disease progression, unacceptable toxicity or withdrawal of patient consent.

Eligibility Criteria

Inclusion Criteria

• Histologically confirmed renal cell carcinoma, stage IV patient.

• Pretreatment CT with or without contrast within 4 weeks prior to the first 18F-Fluciclatide PET scan.
• Evidence of unidimensionally measurable lesion(s) by RECIST criteria version 1.1.
• No prior systemic anti-angiogenic therapy for metastatic disease; prior antiangiogenic therapy used as an adjuvant therapy is allowed if it is completed 6 or more months before study enrollment.

• Be ambulatory and have an Eastern Cooperative Oncology Group (ECOG) performance status 0-2.
• Have a life expectancy of at least 3 months.
• Adequate medical condition in the judgment of the investigator
• Be willing and able to comply with the protocol for the duration of the study.
• Be willing and able to implement effective contraceptive practice
• Give written informed consent prior to study-specific screening procedures, with the understanding that the patient has the right to withdraw from the study at any time, without prejudice.

Exclusion Criteria

• Received another IMP within 30 days before the first administration of 18F-Fluciclatide injection.
• Inability to perform 18F-Fluciclatide PET imaging studies due to physical inability or claustrophobia.

• Chemotherapy within 2weeks, or received radiotherapy to the region of the target lesion, surgery of target lesion within 2 weeks prior to the first 18F-Fluciclatide PET scan
• Pregnant, nursing women or patients with reproductive potential without contraception.
• Current treatment on another therapeutic clinical trial(except Pazopanib study)
• Any patients with known allergy to the GE health care product or any or its excipients should be excluded from the study
• Any condition that, in the opinion of the investigator, would compromise the well-being of the subject or the study or prevent the subject from meeting or performing study requirements.
