First Posted : May 20, 2010
Last Update Posted : December 5, 2016
The purpose of this study is to evaluate Sorafenib and local microtherapy guided by Primovist enhanced MRI in patients with inoperable liver cancer (HCC).
Patients with a diagnosis of hepatocellular carcinoma will receive either:
- local ablation therapy of liver lesions by radiofrequency ablation followed by sorafenib or placebo (local ablation group), or
- radioembolization (SIRT) + sorafenib or sorafenib alone (palliative treatment group).
In each study group, patients will be randomized to one of the two treatment arms following a pre-defined randomization plan. Randomization will be on a 1:1 basis in the local ablation group and on the basis of 10 (sorafenib only) : 11 (SIRT + sorafenib) in the palliative treatment group.
Patients in the local ablation group will be followed at 2 months intervals for recurrence and overall survival, patients in the palliative treatment group will be followed for overall survival. Follow-up in each study group will end 24 months after inclusion of the last patient into the respective study group.
The assignment of patients to the local ablation or palliative study group will be based on the ablative potential of RFA (local ablation if ≤4 tumors, each ≤5 cm in size). Diagnostic imaging will be used to guide this decision. The assignment to the local ablation or the palliative treatment group will be made by the local investigator.
As a sub-study, all patients will undergo Primovist®-enhanced MRI in addition to contrast-enhanced CT before assignment to one treatment group. The goal of the sub-study is to assess the value of Primovist®-enhanced MRI to correctly stratify patients for a local ablation or palliative treatment strategy. Primovist®-enhanced MRI will be compared with contrast-enhanced multislice CT using a truth panel assessment as the standard of reference. In addition, Primovist-enhanced MRI and contrast-enhanced CT will be obtained during follow-up of patients in the local ablation group to assess its potential for detection of recurrence.

local ablation group
Local ablation group: Potentially curative treatment of early HCC includes surgical resection and local ablation (RFA, PEI, BT). Recurrence rates after such approaches are reported to amount to 50% at 3 years and 70% at 5 years. Tumor recurrence may be either due to de novo development of new primary tumors or due to intrahepatic (unrecognized) metastases. Prevention of recurrence after local ablation is an important strategy to improve overall survival. So far, adjuvant chemoembolization and chemotherapy have not proven to be effective in preventing recurrences. There is, however, a strong rationale to assume that sorafenib will be of value in the adjuvant treatment of HCC as sorafenib has a dual mechanism of action (inhibition of tumor proliferation and antiangiogenesis) and has proven efficacy in HCC.
A max.of 2 percutaneous RFA sessions is permitted per patient with a max.of 2 liver lesions treated in each RFA session. Randomization to sorafenib or placebo is performed after completion of RFA. Percutaneous RFA is to be performed according to the manufacturer's instructions and following as far as possible routine procedures of the participating hospital. Typically, RFA will be performed under conscious sedation, general anesthesia is permitted. After local anesthesia of the site of puncture, the applicator is positioned in the center of the lesion using ultrasound-, CT- or MR-guidance. The success of ablation is to be controlled directly after RFA using ultrasound, contrast-enhanced CT, or MR imaging. If for any reason RFA is deemed incomplete within the immediate follow-up (up to 2 weeks after the initial ablation), RFA is to be repeated once (in this case, the total (max.) number of RFA sessions will be three).
The study procedure guide will contain further instructions for RFA.

Active Comparator: palliative treatment group
Radioembolization has been reported to be effective in patients with unresectable HCC with preserved liver function from a number of trials. Successful downstaging of disease rendering patients eligible for potentially curative therapies, and even histologically confirmed complete responses of unresectable HCC, have repeatedly been reported providing the rationale to evaluate SIRT+sorafenib in comparison to sorafenib alone.
The impact of cirrhosis as a concomitant disease in most patients with HCC is that it limits the ability of many patients to tolerate chemotherapy and is an independent cause of death in HCC patients. Thus, the historical difficulty in demonstrating an effect of therapy on survival in patients with advanced-stage, unresectable HCC (the majority). A new therapy that is effective in controlling hepatic disease, is less toxic than traditional chemotherapy, and improves the quality of life for patients in the advanced stages of HCC could represent an alternative.
Procedure: Radioembolization (SIRT)
One SIRT prescription consists of the pre-treatment assessment followed by one or 2 treatment sessions The aim of pre-treatment assessment is to ensure delivery of the microspheres to the target. Evaluation includes a determination of the arterial location and any consequent necessity for coil-embolization of the gastroduodenal artery, right gastric artery and any other accessory arteries to prevent inadvertent administration of microspheres into the gastrointestinal tract or pancreas. In addition, parasitic extrahepatic supply should be coil-embolized.
Patients in whom the shunt fraction indicates potential exposure to the lung to an absorbed radiation dose of more than 30 Gy should be excluded from treatment with SIR-Spheres. Patients who are randomized to receive SIRT but who are not regarded as eligible for SIRT after the pre-treatment assessment will be switched to the sorafenib only group within the palliative treatment arm.
- time to recurrence [ Time Frame: 13-18 months (average time to recurrence) ]In patients in whom local ablation therapy is appropriate, to determine if the sorafenib in combination with radiofrequency ablation (RFA) prolongs the time-to-recurrence (TTR) in comparison with RFA + placebo.
- overall survival [ Time Frame: 10-15 months (average survival) ]
In patients in whom RFA is NOT appropriate (palliative treatment group), to determine if the combination of yttrium-90 microspheres (SIRT) + sorafenib improves the overall survival (OS) in comparison to sorafenib alone.
Interim analysis will be conducted after 60 and 180 deaths and a final analysis after 240 deaths.
- Primovist®-enhanced MRI is non-inferior or superior compared with contrast-enhanced multislice CT [ Time Frame: 3 years ]
To confirm in a 2-step procedure that Primovist®-enhanced MRI is non-inferior (first step) or superior (second step) compared with contrast-enhanced multislice CT for assignment of patients to a palliative vs. local ablation treatment strategy.
The overall study is successful, if the primary objectives 1 OR 2 are met, AND Primovist-enhanced MRI is at least non-inferior to contrast-enhanced CT for treatment stratification.
- quality of life [ Time Frame: 3 years ]assess health-related quality of life via ECOG questionnaire
- safety of RFA [ Time Frame: 3 years ]To assess the safety of the combination of RFA + sorafenib in comparison to RFA + placebo
- safety of SIR Spheres [ Time Frame: 3 years ]To assess the safety of the combination of SIR-Spheres therapy and sorafenib in comparison to sorafenib alone.
