[18]F-Fluciclatide for Kidney Cancer Imaging Studies and Treatment



- The experimental contrast agent [18]F-Fluciclatide is being tested for cancer treatment imaging studies. It is designed to show tumors in which new blood vessels are growing. Imaging studies with [18]F-Fluciclatide may help predict how well a tumor will respond to therapy that will prevent the growth of new blood vessels. Researchers will test [18]F-Fluciclatide before beginning treatment and after the first treatment cycle. Participants may also have a third scan with [18]F-Fluciclatide between 2 and 7 days after starting treatment to look for changes in blood vessel growth early after starting therapy.


- To test the safety and effectiveness of [18]F-Fluciclatide in predicting cancer treatment outcomes.


- Individuals at least 18 years of age who will have kidney cancer treatment to stop tumor blood vessel growth.


- Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Tumor imaging studies and biopsies will be performed before starting the study.

- Participants will have two positron emission tomography (PET) and computed tomography (CT) scans. [18]F-Fluciclatide will be used for each scan. One scan will happen before the start of cancer treatment, and the second will happen after the first treatment cycle.

- Participants may also have an optional third PET/CT scan with [18]F-Fluciclatide. This scan will take place 2 to 7 days after beginning therapy.

- Depending on the location of the tumor, some participants may have an optional magnetic resonance imaging scan to look for changes in tumor blood flow and size. These scans will be done within 3 weeks of each [18]F-Fluciclatide PET/CT scan.

- The scans will be monitored with regular blood tests and vital signs.

- Participants will be followed for up to 1 year after the study to look for overall disease response to therapy.

Detailed Description


- Fluciclatide is a small cyclic peptide containing the RGD tri-peptide, which preferentially binds with high affinity to Alpha(v)Beta(3) integrins, which are up-regulated in and may regulate angiogenesis.

- Alpha(v)Beta(3) integrins are also expressed on certain types of tumor cells, such as renal cell cancer.

- [18F] Fluciclatide (previously known as 18F-AH111585) is a new radiopharmaceutical developed for PET imaging, which targets Alpha(v)Beta(3) receptors.

- Initial and ongoing clinical studies performed in Europe and an ongoing multicenter phase 2 proof-of-concept study (which is currently open at the NIH Clinical Center); demonstrate to date that [18F] Fluciclatide is safe and well tolerated.


- To determine tumor uptake and retention of [18F] Fluciclatide before and after 1 cycle of treatment with targeted anti-angiogenic therapy in renal cell cancer.


- Adult subjects (greater than or equal to18 years old), with documented renal or metastatic renal cancer, with at least one tumor greater than or equal to1 cm in diameter outside of the liver, who are scheduled to enroll in a therapy protocol using an anti-angiogenic agent.

- The subject has a platelet count of >100,000 times 10(6)/L, hemoglobin value of >9 g/dL, prothrombin time (PT) and an activated partial thromboplastin time (aPTT) within <2 times normal limits.

- The subject has not received any targeted anti-angiogenic agents within 60 days prior to pre-treatment (baseline) [18F] Fluciclatide PET imaging.


This will be a pilot, open-label, proof-of-concept study to assess the magnitude of changes in [18F] Fluciclatide PET tumor uptake following treatment with an anti-angiogenic therapy. We expect to enroll 30 evaluable patients in this single center study. When possible, the data analysis will be stratified based on the anti-angiogenic agent received. Subjects will undergo at least two [18F] Fluciclatide PET/CT imaging studies, one pre-therapy and one following completion of 1 cycle of therapy. An optional early post-therapy (2-7 days post therapy commencement) [18F] Fluciclatide PET/CT may be performed. The magnitude of [18F] Fluciclatide uptake on the preand post- treatment PET/CT studies will be evaluated to determine if there is a measureable difference in uptake. Subjects may also undergo standard of care imaging studies as part of routine tumor assessments specified in referring protocols (e.g. diagnostic CT, FDG-PET/CT, etc). Data from the subject s referring therapy protocol will be reviewed for up to one year after anti-angiogenic therapy initiation to assess for tumor response or progression and its relationship to [18F] Fluciclatide PET/CT imaging. Some patients will also undergo optional DCE-MRI scans of the target lesion and in those subjects a comparison between MR parameters and [18F]

Fluciclatide parameters will be made.
