Selective Internal Radiation Therapy (SIRT) Using SIR-Spheres® Y-90 Resin Microspheres on DoR & ORR in Unresectable Hepatocellular Carcinoma Patients (NCT04736121)

A Prospective, Multicenter, Open-label Single Arm Study Evaluating the Safety & Efficacy of Selective Internal Radiation Therapy Using SIR-Spheres® Y-90 Resin Microspheres on DoR & ORR in Unresectable Hepatocellular Carcinoma Patients

🔵 Active, Not Recruiting Observational / Diagnostic ⚙️ Medical Device Protocol Sponsor: Sirtex Medical

🩺 Plain-English Summary (8th-Grade Level)

The objective of this pivotal study is to evaluate the safety and effectiveness of SIRT using SIR-Spheres Y-90 resin microspheres as first-line treatment for local control of HCC in patients with Barcelona Clinic Liver Cancer (BCLC) stage A, B1, B2, and C. SIR-Spheres consist of biocompatible resin microspheres containing yttrium-90 (Y-90), with a size between 20 and 60 microns in diameter. Y-90 is a high-energy pure beta-emitting isotope with no primary gamma emission. SIR-Spheres are indicated for the local tumor control of unresectable hepatocellular carcinoma (HCC) in patients with Barcelona Clinic Liver Cancer (BCLC) stage A, B1 and B2, maximal single lesion size of 8 cm, no macrovascular invasion, well-compensated liver function and good performance status. It is also indicated for the treatment of unresectable metastatic liver tumors from primary colorectal cancer with adjuvant intra-hepatic artery chemotherapy (IHAC) of Floxuridine (FUDR).
