TAF Monotherapy Versus ETV Combined With TAF on the Efficacy and Prognosis of Immunotherapy for Hepatitis B-Related Hepatocellular Carcinoma
Prospective, Randomized, Controlled Clinical Study Comparing TAF Monotherapy Versus ETV Combined With TAF on the Efficacy and Prognosis of Immunotherapy for Hepatitis B-Related Hepatocellular Carcinoma
Source: ClinicalTrials.gov · Last updated 28 Nov 2025
Brief summary (registry, in English)
Study Objective: To compare the efficacy and prognosis of systemic cancer therapy between TAF monotherapy and ETV plus TAF combination therapy in patients with unresectable, advanced hepatitis-B-related hepatocellular carcinoma (HBV-HCC). Study Design: Prospective, interventional cohort study. Participants: Patients with histologically or radiologically confirmed unresectable, advanced HBV-HCC who are scheduled to receive immune-based systemic therapy at The Third Affiliated Hospital of Sun Yat-sen University. Detailed inclusion/exclusion criteria are provided below. Intervention: Enrolled participants will be assigned to receive either TAF monotherapy or ETV combined with TAF for HBV suppression. Primary Outcome: Overall survival (OS) at 24 months after initiation of systemic therapy, compared between the two HBV-treatment strategies. Secondary Outcomes: Decline in HBV DNA and HBsAg levels at 1, 3, 12 and 24 months. Sample Size: 120 HCC patients (60 per arm). Statistical Analysis: All analyses will be performed with SPSS. Continuous variables will be tested for normality (Shapiro-Wilk). Normally distributed data are presented as mean ± SD; non-normally distributed data as median (IQR). Twenty-four-month OS will be estimated by Kaplan-Meier curves and compared with a Cox proportional-hazards model adjusted for age, BCLC stage, AFP level, and ICI regimen. PFS will be compared using the log-rank test; ORR and HBV DNA undetectable rate will be compared with χ² tests. Inverse-probability-of-treatment weighting (IPTW) will address selection bias, and multiple imputation will handle missing data.
