Phase II Study Therasphere® (Yttrium-90) in Combination With Systemic Therapy in Patients With High-risk Hepatocellular Carcinoma
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.
• 3.1.1 Patients must have a diagnosis of hepatocellular carcinoma (HCC) confirmed by American Association for Study of Liver Diseases (AASLD) guidelines with a Childs-Pugh score of A or B7 \[Appendix 5\] NOTE: If the patient does not have histological confirmation of disease by biopsy, diagnosis of HCC must be documented with approval by a tumor board or other multidisciplinary conference. Please refer to the appropriate source documents.
• 3.1.2 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.
• 3.1.3 Patients may be treatment -naïve or have received any number of prior therapies. NOTE: Prior cancer targeted immunotherapy for any other cancer is contraindicated and not permitted.
• 3.1.4 Adults ≥18 years old of either gender are eligible.
• 3.1.5 Patients must exhibit an ECOG performance status of 0, 1, or 2 \[Appendix 1\]
• 3.1.6 Patients must have adequate organ function prior to registration as determined by: Hemoglobin (HgB) ≥ 8.5 g/dL (without the use of growth factors, transfusion permitted), Absolute Neutrophil Count (ANC) ≥ 50 x 109/L (without use of growth factors \[i.e., IL-11\], transfusion permitted to achieve this value), Prothrombin time (PT)/ International normalized ratio ≤ 2.3 or PT ≤ 6 seconds above control, Calculated creatinine clearance (CrCl) or 24-hour urine CrCl \> 30 mL/min, Serum Bilirubin ≤ 3 times the upper limit of normal (ULN), AST 10X ULN, ALT 10X ULN
• 3.1.7 Females of childbearing potential (FOCBP), and non-sterilized males who are sexually active must agree to the use of two methods of contraception, with one method being highly effective and the other method being either highly effective or less effective as listed in Appendix 3. They must also refrain from egg and/or sperm cell donation and breastfeeding for 90 days after the final dose of investigational product(s). FOCBP are defined as those who are not surgically sterile (i.e., bilateral tubal ligation, bilateral oophorectomy, or complete hysterectomy) or postmenopausal (defined as 12 months with no menses without an alternative medical cause) FOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment. Men who are sexually active with FOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment.
• 3.1.8 FOCBP must have a negative pregnancy test (Serum or urine pregnancy test per site investigator discretion) prior to registration.
• 3.1.9 Patients must have the ability to understand and the willingness to sign a written informed consent prior to registration on study.
