Sintilimab Plus Bevacizumab and SIRT for Intermediate-advanced HCC

Phase 2
Recruiting
Conditions
Hepatocellular Carcinoma Non-resectable
Interventions
Drug: Sin-Bev-SIRT
Registration Number
NCT06397222
Lead Sponsor
Second Affiliated Hospital of Guangzhou Medical University
Brief Summary

This study is conducted to evaluate the efficacy and safety of sintilimab, bevacizumab plus Y-90 selective internal radiation therapy (SIRT) for patients with unresectable intermediate-advanced hepatocellular carcinoma (HCC).

Detailed Description

This is a single-center, prospective study to evaluate the efficacy and safety of sintilimab, bevacizumab plus SIRT (Sin-Bev-SIRT) in patient with unresectable HCC.

23 patients with unresectable intermediate-advanced HCC (BCLC B/C stage) will be enrolled in this study. The patients will receive sintilimab (200mg I.V. Q3W) and bevacizumab (7.5mg/kg I.V. Q3W) at 3-7 days after SIRT. Sintilimab and bevacizumab will last up to 24 months, or until disease progresses, intolerable toxicity, withdrawal of informed consent, loss of follow-up, death, or other circumstances that require termination of treatment, whichever occurs first.

The primary end point of this study is Progression free survival (PFS) per mRECIST. The secondary endpoints are PFS per RECIST 1.1, objective response rate (ORR), disease control rate (DCR), overall survival (OS) and adverse events (AEs).
