ClinConnect Summary

This clinical trial is studying a new combination treatment for patients with potentially resectable hepatocellular carcinoma (HCC), which is a common type of liver cancer. The researchers are testing the effectiveness and safety of a treatment that includes a specific chemotherapy technique called hepatic arterial infusion chemotherapy (HAIC) using irinotecan liposomes, along with two other drugs: adebrelimab and bevacizumab. The goal is to see if this combination can help control the cancer and improve outcomes for patients who may be candidates for surgery.

To participate in this trial, patients need to be between 18 and 75 years old and have a confirmed diagnosis of HCC. They should not have received any previous treatment for their cancer and must have at least one measurable tumor that can be assessed. Participants will undergo regular monitoring and assessments during the study to evaluate how well the treatment is working and to check for any side effects. It’s important for patients to discuss this opportunity with their healthcare team to understand if they meet the eligibility criteria and what participating in the trial would involve.
