Sirtex Medical Wins Device OK for Liver Cancer
FDA has approved a Sirtex Medical PMA for its SIR-Spheres Y-90 resin microspheres for treating unresectable hepatocellular carcinoma (HCC) in the United States. HCC is the most common form of liver cancer in adults in the U.S., according to the American Cancer Society.
Radioembolization with SIR-Spheres uses personalized dosimetry to deliver the optimal dose of radiation directly to tumors in patients with HCC, the company says. “The expanded indication makes SIR-Spheres the only Y-90 treatment approved in the U.S. for both HCC and mCRC [metastatic colorectal cancer],” it says.
Approval is based on data from the DOORwaY study that enrolled 100 patients across 18 U.S. centers. The study met its prespecified co-primary endpoints, demonstrating a best overall response rate (ORR) of 98.5% as assessed by independent central review, Sirtex says. “All evaluable patients demonstrated a response, indicating a 100% local tumor control rate,” it adds. “Additionally, the median duration of response (DoR) exceeded 300 days.”
