ondansetron: Ondansetron: Maintained at 8mg/qd, orally, until disease progression or intolerance.
Study summary
This study is a prospective, randomized, single-center randomized controlled clinical trial to investigate the safety and efficacy of ondansetron in reducing the toxicity associated with immune checkpoint inhibitor treatment. This study plans to enroll 134 patients with hepatocellular carcinoma who are scheduled to receive standard ICI treatment. This study will adopt the 2023 CSCO Guidelines for the Management of Immune checkpoint inhibitor-related toxicity as the main assessment criterion, and take the incidence and severity of irAEs as the main observation indicators to evaluate the effectiveness of ondansetron in reducing the toxicity related to immune checkpoint inhibitor treatment in patients with hepatocellular carcinoma.

9. The researcher evaluated that the patient was unable or unwilling to comply with the requirements of the research protocol.
Primary outcome measure(s)
The incidence rate of irAEs — through study completion, an average of 1 year To evaluate whether the prophylactic use of ondansetron can reduce the incidence of immune-related adverse events (irAEs) in patients treated with immune checkpoint inhibitors (ICI). The evaluation criteria mainly refer to the "2023 CSCO Guidelines for the Management of Toxicity Related to Immune Checkpoint Inhibitors", with a focus on the incidence of all grades of irAEs and the incidence of severe irAEs at grade 3 and above. The monitoring scope covers liver and kidney functions, blood routine, cardiac function (electrocardiogram, myocardial injury markers), endocrine function (thyroid function, etc.) and imaging manifestations of pneumonia.
