Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to evaluate whether prophylactic endoscopic variceal ligation (EVL) can prevent esophageal variceal bleeding in patients with hepatocellular carcinoma (HCC) receiving atezolizumab and bevacizumab (Atezo/Bev) therapy. The study will also assess the safety of prophylactic EVL in this population.

The main question it aims to answer is:

Does prophylactic EVL in high-risk varices reduce the incidence of variceal bleeding to a level similar to that of low-risk varices in HCC patients receiving Atezo/Bev?

Participants will:

1. Undergo prophylactic EVL before starting Atezo/Bev therapy (within 2 weeks ± 1 week before the first dose).
2. Start Atezo/Bev therapy 2 weeks (± 1 week) after EVL.
3. Have follow-up endoscopies (EGD) one week after the 3rd, 5th, and 7th doses of Atezo/Bev.

If varices improve, no additional intervention is needed. If varices persist or worsen, on-demand EVL will be performed, and Atezo/Bev will continue.

This study will help determine if prophylactic EVL should be a standard strategy for managing high-risk varices in HCC patients undergoing Atezo/Bev therapy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

1. Backgrounds Patients with hepatocellular carcinoma (HCC) undergoing treatment with atezolizumab plus bevacizumab (Atezo/Bev) are at a high risk of variceal bleeding. When bleeding occurs, it may necessitate treatment delays or permanent discontinuation of Atezo/Bev, potentially requiring a switch to alternative anticancer therapies that may be less effective. Additionally, variceal bleeding can result in hepatic decompensation, deteriorated liver function, and reduced quality of life.

Prophylactic endoscopic variceal ligation (EVL) has been proposed as an approach to minimize the risk of variceal hemorrhage in patients with high-risk esophageal varices, as identified on screening endoscopy. By proactively treating high-risk varices before initiating Atezo/Bev, prophylactic EVL may optimize oncologic treatment continuity and overall patient outcomes.
2. Study aim

This Phase 2 study is designed to evaluate the efficacy and safety of prophylactic EVL in reducing variceal bleeding among HCC patients with high-risk esophageal varices undergoing Atezo/Bev therapy. In addition, this study aims to:

\- Assess the impact of prophylactic EVL on patient survival and quality of life.

\- Identify biomarkers associated with variceal bleeding risk and therapeutic response.

3\. Study Design

1. Prophylactic EVL Procedure Prophylactic EVL will be performed within two weeks (± 1 week) before the initiation of Atezo/Bev therapy. The procedure will be conducted by board-certified gastroenterological endoscopists with expertise in therapeutic endoscopy.

\- EVL technique: Suctioning of esophageal varices until the red-out phenomenon occurs. Placement of a rubber band at the variceal base to induce thrombus formation, leading to subsequent necrosis and sloughing. The procedure begins at the distal esophageal varices and progresses spirally upward. Priority treatment will be given to varices with active bleeding or endoscopic signs of recent hemorrhage.
2. Follow-Up Endoscopy and Additional EVL Criteria Follow-up esophagogastroduodenoscopy (EGD) will be conducted one week after the 3rd dose of Atezo/Bev to assess variceal status.

If any of the following criteria are met, additional EVL will not be performed, and Atezo/Bev therapy will continue two weeks later:
* Varices have regressed to F1 or less
* Red color signs have disappeared If these criteria are not met, an on-demand EVL session will be performed.
3. Further On-Demand EVL Strategy Additional on-demand EVL sessions will be considered after the 5th and 7th doses of Atezo/Bev, with EGD follow-up before each session.

The maximum number of EVL sessions will be limited to three during the study period.

Group Type EXPERIMENTAL

Endoscopic variceal ligation (EVL)

Intervention Type PROCEDURE

1. EVL for high-risk varices will be performed by experienced endoscopists, certified in gastroenterological endoscopy, within two weeks prior to the initiation of the Atezo/Bev.
2. A follow-up EGD will be conducted one week after the Atezo/Bev #3. If any of the following criteria are met, additional EVL will not be performed, and anticancer treatment will proceed two weeks later. Otherwise, an additional on-demand EVL session will be conducted:

* The esophageal varices have improved to F1 or less.
* The red color sign has disappeared.
3. On-demand EVL will be considered after 5th, and 7th consecutive doses of Atezo/Bev, with EGD follow-up performed to assess eligibility. The maximum number of EVL sessions is limited to three sessions.
