Interventions

  • ttrium-90 microspheres in combination with nivolumab, ipilimumab, and lenvatinib in patients with unresectable hepatocellular carcinoma — DRUG
    The phase Ib portion of the trial explores the incidence of dose-limiting toxicity (DLT) in the quadruple therapeutic regimen. Three weeks after receiving Y90-SIRT, the patients are assigned to one of three dose exploration cohorts: (1) nivolumab 1 mg/kg IV every 3 weeks (Q3W) + ipilimumab 1 mg/kg IV Q3W for up to 4 cycles; (2) nivolumab 1 mg/kg IV Q3W + ipilimumab 2 mg/kg IV Q3W for up to 4 cycles; (3) nivolumab 1 mg/kg IV Q3W + ipilimumab 3 mg/kg IV Q3W for up to 4 cycles. After completion of ipilimumab administration, nivolumab is continued at 480 mg IV every 4 weeks (Q4W) until disease progression, unacceptable toxicity, withdrawal of informed consent, or a maximum treatment duration of two years. Lenvatinib is then administered after discontinuation of ipilimumab, in combination with nivolumab, at a dose of 8 mg (body weight \<60 kg) or 12 mg (body weight \>60 kg) orally once daily (PO QD), taken at a fixed time each day, with or without food.

Study Details

This clinical trial was designed to evaluate the safety and efficacy of Y90-SIRT combined with nivolumab, ipilimumab, and lenvatinib in patients with unresectable HCC. In addition to assessing short-term efficacy endpoints, such as ORR and PFS, this trial places particular emphasis on the OS benefit for patients. This study is therefore both novel and innovative.

Arms

  • Experimental: Yttrium-90 microspheres in combination with nivolumab, ipilimumab, and lenvatinib
    The phase Ib portion of the trial explores the incidence of dose-limiting toxicity (DLT) in the quadruple therapeutic regimen. Three weeks after receiving Y90-SIRT, the patients are assigned to one of three dose exploration cohorts: (1) nivolumab 1 mg/kg IV every 3 weeks (Q3W) + ipilimumab 1 mg/kg IV Q3W for up to 4 cycles; (2) nivolumab 1 mg/kg IV Q3W + ipilimumab 2 mg/kg IV Q3W for up to 4 cycles; (3) nivolumab 1 mg/kg IV Q3W + ipilimumab 3 mg/kg IV Q3W for up to 4 cycles. After completion of ipilimumab administration, nivolumab is continued at 480 mg IV every 4 weeks (Q4W) until disease progression, unacceptable toxicity, withdrawal of informed consent, or a maximum treatment duration of two years. Lenvatinib is then administered after discontinuation of ipilimumab, in combination with nivolumab, at a dose of 8 mg (body weight \<60 kg) or 12 mg (body weight \>60 kg) orally once daily (PO QD), taken at a fixed time each day, with or without food.

Primary Outcome Measure

Incidence of dose-limiting toxicity (DLT) of the quadruple regimen (Y90-SIRT plus nivolumab, ipilimumab, lenvatinib) [ Time Frame: Up to 4 treatment cycles (each cycle is 3 weeks) ]
