Sintilimab Plus Bevacizumab and SIRT for Intermediate-advanced HCC

Официальное название

Sintilimab, Bevacizumab Plus Y-90 Selective Internal Radiation Therapy for Patients With Unresectable Intermediate-advanced Hepatocellular Carcinoma: a Prospective, Single-center, Single Arm Trial

Обзор

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).

Подробное описание

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).

Вмешательства

• Препарат Sin-Bev-SIRT
  Sintilimab 200mg I.V. q3w and bevacizumab 7.5mg/kg I.V. q3w will be started at 3-7 days after the first SIRT. Treatment of sintilimab and bevacizumab will last up to 24 months. Patients will be allowed to have sintilimab or bevacizumab as a sigle agent and will be still considered on study when the other drug cause intolerable toxicity.
