An Open-Label, Prospective, Multi-Center Clinical Trial to Evaluate the Efficacy and Safety of TheraSphere™ Followed by Durvalumab (Imfinzi®) With Tremelimumab (Imjudo®) for Hepatocellular Carcinoma (HCC)

The objective of the ROWAN clinical study is to assess the efficacy of local tumor control in HCC patients who receive TheraSphere followed by durvalumab and tremelimumab.

A global open-label, prospective, multi-center Phase II trial designed to assess the safety and efficacy of TheraSphere administered before initiation of Durvalumab with Tremelimumab in HCC patients who are not a candidate for resection, thermal ablation or liver transplant at the time of study entry.

Inclusion Criteria:

         1. Participants must be aged ≥18 years at the time of screening.

         2. Written informed consent and any locally required authorization (e.g., Health Insurance Portability and accountability Act in the US, European Union (EU) data privacy regulations in the EU) obtained from the patient/legal representative prior to performing any protocol-related procedures, including screening evaluations.

             1. Previous TACE performed ≥8 months before TheraSphere administration and

             2. Result of previous TACE was CR and

             3. Current tumor is not a recurrence of previously treated lesion

         13. Patients with portal vein thrombosis (PVT) Vp0, Vp1, or Vp2.

         14. Patients with HBV or HCV infection are to have documented virology status of hepatitis as confirmed by HBV and HCV serology test:

Patients with HBV infection: HBV DNA load should be ≤2000 IU/mL obtained within 42 days prior to initiation of study treatment, and Anti-HBV treatment (per local standard of care; e.g., entecavir) for a minimum of 14 days prior to study entry and willingness to continue treatment for the length of the study

             2. Patients with chronic HCV infection are allowed in the study: for untreated patients, AST/ALT should be ≤3xULN and for treated patients, antiviral treatment (per local standard of care) should be stopped for a minimum of 14 days prior to study entry and AST/ALT should be ≤3xULN

         15. Patients with Human Immunodeficiency Virus (HIV) infection are eligible, provided the HIV infection is well controlled with no current or previous AIDS-related complications and CD4+ T-cell (CD4+) counts ≥ 350 cells/uL

         3. 99mTc-MAA hepatic arterial perfusion scintigraphy shows poor tumor and/or portal vein thrombosis (PVT) targeting that would lead to a dose that does not meet the liver dosing criteria.

         4. Shunting of blood to the lungs that could result in delivery of >30 Gy to the lungs in a single treatment or >50 Gy cumulative dose to the lungs in case of multiple TheraSphere treatments, as seen on 99mTc-MAA hepatic arterial perfusion scintigraphy.
