Brief summary: The purpose of this research is to compare progression free survival between two available systemic therapies - immunotherapy and tyrosine kinase inhibitors - after Therasphere® (yttrium-90) treatment in adult patients with advanced hepatocellular carcinoma. The immunotherapy consists of a standard-of-care treatment with Atezolizumab and Bevacizumab. Treatment with tyrosine kinase inhibitors consists of standard-of-care Lenvatinib or Cabozantinib.

Detailed description: PRIMARY OBJECTIVES:

I. To compare Progression Free Survival (PFS) in patients with advanced HCC who receive Y90 followed by immunotherapy (atezolizumab + bevacizumab, Arm A) or Y90 followed by TKI treatment ( lenvatinib or cabozantinib, Arm B). For ARM B, \[patients will receive Lenvatinib. If they have prior history of treatment with Lenvatinib, then can be given Cabozantinib\]..

SECONDARY OBJECTIVES:

I. To compare the Time to Progression (TTP) in patients with advanced HCC who receive Immunotherapy combination compared to TKI following Y90.

II. To compare the Objective Response Rate (ORR) as assessed by RECIST v1.1 in patients with advanced HCC who receive immunotherapy combination and those who receive TKI treatment after Y90.

III. To compare the Duration of Response (DOR) in patients with advanced HCC who receive immunotherapy combination and those who receive TKI treatment after Y90.

IV. To compare the Clinical Benefit Rates (CBR) \[CR, PR,SD\] as assessed by RECIST v1.1 in patients with advanced HCC who receive immunotherapy combination and those who receive TKI treatment after Y90.

V. To compare the Overall Survival (OS) in patients with advanced HCC who receive immunotherapy combination and those who receive TKI treatment after Y90.

VI. To compare the safety and tolerability of patients with advanced HCC who receive immunotherapy combination and those who receive TKI treatment after Y90, as defined by NCI CTCAEv5.

OUTLINE:

Patients will first be treated one time with liver directed therapy, Therasphere® (Y-90), following institutional procedures. After completion of Y- 90, patients will have some recovery time (14-21 days) prior to starting systemic therapy.

Patients will be followed up for 2 years after completion of study treatment.

Please refer to the appropriate source documents.
* Patients must have at least 1 lesion that is measurable using RECIST guidelines. NOTE: A previously irradiated lesion can be considered a target lesion if the lesion is well defined, measurable per RECIST, and has clearly progressed.
