Combined Y-90 Selective Internal Radiation Therapy (Y-90 SIRT) and Stereotactic Body Radiation Therapy (SBRT) in Unresectable Hepatocellular Carcinoma (HCC)
Study Details
Study Description
Brief Summary
This study will investigate the combination of Ytrium-90 (Y-90) Selective Internal Radiation Therapy (SIRT) followed by Stereotactic Body Radiation Therapy (SBRT). Y-90 SIRT alone or SBRT alone are standard procedures used in the treatment of liver cancer. This study will assess the combination of Y-90 SIRT and SBRT and obtain preliminary information about the side effects and safety of the combination therapy. Additionally, this is the first time that Y-90 PET-CT imaging will be included in planning for SBRT.

Detailed Description
Selective Internal Radiation Therapy (SIRT) is a technique where radiation is internally delivered to a tumor. In SIRT, small radioactive beads are deposited in the liver through a large blood vessel (hepatic artery). SIRT that uses the radioactive material Yttrium-90 is called Y-90 SIRT.
Stereotactic Body Radiation Therapy (SBRT) is a technique where radiation is externally delivered to a tumor. In SBRT, a machine produces a beam of radiation that targets the tumor from outside the body.
After receiving Y-90 SIRT, participants will be evaluated to estimate how much radiation was absorbed by their tumors during Y-90 SIRT. Y-90 PET-CT imaging will be used to help plan SBRT, which will target areas of tumors that did not receive as much radiation as expected during Y-90 SIRT.

Outcome Measures
Primary Outcome Measures
- Change in Child-Turcotte-Pugh (CTP) score >= 2 points from baseline [Up to 6 months after SBRT]
The primary safety endpoint is the binary indicator for a CTP increase of 2 or more points within 6 months and relative to pre-SBRT baseline. An increase of 2 or more points indicates clinically significant liver decompensation.
- Incidence of toxicities of grade 3 or higher [Up to 6 months after SBRT]
A secondary safety endpoint is grade 3+ toxicity within 6 months relative to pre-SBRT baseline. Assessed by NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
- Number of patients with a change in albumin + bilirubin (ALBI) level of >= 0.5 [Up to 6 months after SBRT]
A secondary safety endpoint is the binary indicator for an increase in ALBI within 6 months relative to pre-SBRT baseline of 0.5 or greater.
Secondary Outcome Measures
- Freedom from local progression (FFLP) at the lesion level [Until progression or last surveillance scan at approximately 24 months after SBRT]
FFLP at the lesion level is defined as the time from SIRT to progression of a SBRT-treated lesion. Progression is defined based on RECIST and mRECIST criteria.
- Freedom from local progression (FFLP) at patient level [Until progression or last surveillance scan at approximately 24 months after SBRT]
FFLP at the patient level is defined as the time from SIRT to progression of the treated lesions including those not targeted by SBRT. Progression is defined based on RECIST v1.1and mRECIST criteria.
- Response rate [Up to 6 months after SBRT]
Response rate defined per RECIST v1.1 and mRECIST criteria and categorized as follows: progressive disease or stable disease = non-responder, partial response or complete response = responder.
- Overall survival [Until death from any cause, or until patient's last follow-up visit, or until study stops; up to approximately 5 years.]
Overall survival will be calculated as the time from Y-90 SIRT treatment to death from any cause, or until patient's last follow-up visit, or until study stops.
