An open-label, prospective, multicenter, randomized, Phase III clinical trial evaluating yttrium-90 transarterial radioembolization (TheraSphere®) in the treatment of patients with unresectable hepatocellular carcinoma (HCC).27,28

TheraSphere® prior to initiation of standard-of-care therapy: sorafenib

Standard-of-care therapy: sorafenib

Primary: Overall survival
Secondary: Time to progression, tumor response, time to symptomatic progression, quality of life (FACT-hep), time to untreatable progression, safety

To evaluate the efficacy and safety of TheraSphere® in patients with unresectable HCC in whom treatment with sorafenib is planned.

Primary Endpoint
  • Overall survival from time of randomization

Secondary Endpoint
  • Time to progression (from time of randomization based on investigator assessment according RECIST criteria v1.1)
  • Time to untreatable progression (from time of randomization based on one or more of the following: investigator assessment according to RECIST criteria v1.1, contraindication to protocol treatments based on package insert or patient performance status)
  • Time to symptomatic progression (from time of randomization to ECOG performance status >1 with or without tumor progression based on investigator assessment according to RECIST criteria v1.1)
  • Tumor response (according to RECIST v1.1 criteria based on investigator assessment)
  • Quality of life (Functional Assessment of Cancer Therapy - Hepatobiliary Questionnaire FACT-hep)
  • Adverse events (CTCAE v4.0)
