Study Endpoints

Primary Endpoints

Objective Response Rate (ORR)
Through study completion, an average of 4 years

The Objective Response Rate (ORR) is defined as the proportion of patients who have either a Partial Response (PR) or a Complete Response (CR) to treatment. CR and PR are the best overall response across all time points of tumor evaluation. Overall tumor response at each time point is assessed according to the modified RECIST criteria for HCC.

Treatment Arms

ArmTypeDescription
Hepatocellular carcinoma with portal vein thrombosis and without hepatic spreadEXPERIMENTALPatient will receive selective internal radiation therapy and immunotherapy as per standard of care. SIRT Administration is direct intra-arterial injection in the hepatic artery to target only liver disease and IO will be performed as describe below: * Tremelimumab (Imjudo®): 300 mg IV, one-hour infusion; * Durvalumab (Imfinzi®): 1500 mg IV, one-hour infusion every 4 weeks.

Interventions

NameTypeDescription
Selective Internal RadiotherapyDEVICESIRT will use Yttrium-90 glass-microspheres (TheraSphereTM). SIRT needs two steps: the treatment simulation (diagnostic angiography and scintigraphy of hepatic perfusion with 99mTc-MAA) and the administration (during a therapeutic angiography).
TremelimumabDRUGTremelimumab should be done 1 to 3 weeks after SIRT and is administrated according to the Summary of Product Characteristic (SPC).
DurvalumabDRUGAfter the end of the tremelimumab infusion, patient receive durvalumab then one injection every 4 weeks until further progression upon investigator decision. Also administrated according to the Summary of Product Characteristic (SPC).
