HepaSphere/Quadrasphere Microspheres for Delivery of Doxorubicin for the Treatment of Hepatocellular Cancer

This phase three, interventional, and prospective study consists of a patient population that has advanced liver cancer (hepatocellular cancer \[HCC\]) that cannot be removed by standard therapies such as surgical removal, liver transplant, and/or ablation. Embolics and drug eluting embolics are being used by interventional radiologists to try and shrink or kill the tumor area. Patients that met eligibility criteria, wanted to participate in the study, and signed the informed consent form (ICF) made up the study subject population. Subjects were randomized on a 1:1 basis (subjects were blinded to arm they were randomized to). Post randomization and within four weeks of the first chemoembolization procedure all subjects had a baseline MRI. Following, the first chemoembolization procedure (hqTACE or cTACE) or 'cycle' was completed. Subjects can (per protocol) receive up to 3 TACE cycles. Within 4 weeks after any TACE cycle, an MRI and labs should be conducted/collected to evaluate disease status (reduction vs progression) and measure treated lesions. Any residual disease that is present after after the first TACE will undergo the next TACE cycle (maximum of three). However, if the liver MRI shows a complete response (absence of HCC) then no additional TACE procedures are performed and the subject is followed for survival.
