the Effect of Grazoprevir/Elbasvir and TACE vs. TACE Alone in Prolonging Survival of Patients With Non-resectable HCV Associated HCC. (ZEPATIER)

Pilot Study to Assess the Effect of Grazoprevir/Elbasvir (ZEPATIER™) and Transarterial Chemoembolization (TACE) vs. TACE Alone in Prolonging Survival of Patients With Non-resectable HCV Associated Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is the fifth most common cancer and the second leading cause of cancer-related deaths in the world. Hepatitis C virus (HCV) is the most common underlying cause of cirrhosis and HCC in the western world. Most patients with HCC present with either non-resectable tumor and/or severe underlying liver dysfunction, and are not suitable candidates for curative treatments by resection or transplantation. Thus, for the majority of patients with HCV related HCC, the only option is prolongation of life without a chance for cure. These patients generally have a poor prognosis with a median survival of less than 1 year. Arterial obstruction of branches of the hepatic artery and simultaneous infusion of chemotherapy (Trans-arterial chemo-embolization or TACE) induces ischemic tumor necrosis with a high rate of objective tumor responses (30-60%). Overall, the median survival after TACE for intermediate HCC is about 20 months, an improvement over supportive care. Treatment with Grazoprevir/Elbasvir showed excellent results in phase 3 studies for patients with HCV genotype 1 (a and b) and genotype 4 infection and is approved for HCV treatment in the USA, Europe and Israel. Anti-HCV therapies may influence HCC biology by decreasing inflammation and may thus alter the tumor microenvironment.

Description détaillée

Single center, open label, prospective pilot study. The study will include 20 HCV genotype 1 (a and b) cirrhotic patients (Child Pugh A compensated cirrhosis) with advanced, un-resectable HCC who are eligible for TACE. This pilot study will have one arm which will be compared to historical controls. All patients participating in the study will receive Grazoprevir/Elbasvir treatment according to established guidelines together with regular TACE treatments. The historical controls will refer to patients who received regular TACE treatments alone (standard of HCC care). Follow up will be for up to 24 months from TACE initiation.

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Expérimental: HCV patients with un-resectable HCC

HCV genotype 1 (a and b) cirrhotic patients (child pugh A compensated cirrhosis) with advanced and un-resectable HCC who are eligible for TACE . The patients will receive Grazoprevir/Elbasvir and Transarterial Chemoembolization.

Their outcomes will be compared to the medical records of patients who underwent Transarterial Chemoembolization only, in the past.
Médicament: Grazoprevir/Elbasvir
anti-viral treatment for HCV
Autre: Medical records
Medical records of patients who underwent Transarterial Chemoembolization only, in the past.
Procédure: Transarterial Chemoembolization
A minimally invasive procedure performed in interventional radiology to restrict a tumor's blood supply. Small embolic particles coated with chemotherapeutic drugs are injected selectively through a catheter into an artery directly supplying the tumor. These particles both block the blood supply and induce cytotoxicity, attacking the tumor in several ways.
