Description of intervention(s) / exposure
This is a pilot study that will be the first in human study to evaluate the feasibility, safety,
toxicity and potential effectiveness of selective internal radiation therapy (SIRT) using SIR-Spheres
microspheres as a treatment for patients with renal cell carcinoma that is not suitable
for curative therapy by conventional means.
Patients will be serially recruited into dose escalating cohorts: 75Gy, 100Gy, 150Gy, 200Gy, 300Gy intended radiation dose to the tumour. If no dose limiting toxicity is evident following completion of recruitment into the 300Gy cohort, then a final cohort of six patients may be recruited. In this final cohort, the angiographic endpoint of “imminent stasis” in the renal artery will serve as the endpoint for delivery of SIR-Spheres microspheres, regardless of actual dose delivered.

Summary
Brief summary
The treatment known as selective internal radiation therapy, or SIRT has been used in human patients since 1998 for the treatment of liver cancer.

This study will be the first time that SIRT treatment has been used in human patients for the treatment of kidney cancer. The primary purpose of this study is to test the safety of SIRT as a treatment for patients with kidney cancer (also known as renal cell carcinoma) that is not suitable for treatment using the standard treatment options available.

While SIRT treatment has been used for over a decade to treat liver cancer, it has not been used before to treat kidney cancer. In this study, four separate groups of patients will be entered into the study. The four groups of patients will each receive a certain dose of selective internal radiation therapy for their kidney cancer. The dose of radiation will start with a low dose in the first group of patients. The dose of radiation will then proceed to successively higher doses of radiation for patient groups two, three and four, if it has been shown safe to do so.

SIRT treatment uses SIR-Spheres microspheres, which are tiny beads about a third the width of a human hair that emit radiation that is designed to kill tumours. Millions of SIR-Spheres are injected by a specially trained doctor known as an Interventional Radiologist into the blood vessel(s) that supply blood to the tumours. After being injected into the blood vessels that supply the tumours, the SIR-Spheres lodge in the tiny blood vessels of the tumour, where they emit their radiation directly into the tumour, with the aim of destroying the tumour.
