Brief summary

This study is being done with a new therapy called Selective Internal Radiation Therapy (known as SIRT). Radiation is an effective treatment for destroying tumors. It is widely used in cancer treatment. However, radiation can harm normal tissue. SIR-Spheres are tiny plastic beads. They contain a radioactive agent called Yttrium-90. These beads can be delivered through a small tube inserted into the blood vessel that goes directly to the tumor. The radiation goes directly to the tumor. This spares healthy parts of your liver.

Interventions

DEVICESIR-spheres® (Selective Internal Radiation Therapy)

SIR-spheres® will be administered at 70%, 85% and 100% of the calculated individual patient dose (approximately 1 month prior to SIR-spheres® administration).The first cohort will receive SIRSpheres® at 70% of the individually calculated patient dose, the second will receive 85% of the calculated patient dose, and the third will receive 100% of the calculated patient dose.

Design outcomes

Primary

MeasureTime frame
To determine the safety, toxicity, and maximum tolerated dose of SIR-Spheres® in patients with unresectable metastatic colorectal cancer to the liver (CLM) who have received previous hepatic arterial infusion chemotherapy (HAC).2 years

Secondary

MeasureTime frame
