Background: Direct high-quality evidence remains absent on the benefits of HBeAg-negative chronic hepatitis B patients (CHB) with normal alanine transaminase (ALT) and positive HBV DNA after nucleos(t)ide analogs (NAs) treatment.
Methods: This is a single-center, open-label, randomized parallel controlled trial with a follow-up duration of 96 weeks. An estimated 300 patients will be recruited at West China Hospital of Sichuan University, China. After stratified by serum HBV DNA (< 2000 vs. ≥ 2000 IU/ml), eligible patients will be randomized (allocation ratio 1:1) to receive either antiviral therapy (the treatment group) or regular examination alone (the control group). The primary outcomes are rates of virological response and changes in the levels of serum HBV pregenomic RNA (pgRNA) and scores of health-related qualities of life.
Discussion: This randomized controlled trial focuses on HBeAg-negative patients with normal ALT, including those of the inactive carrier phase and the grey zone, whose antiviral treatment remains controversial. Additionally, a health-related quality of life scale is introduced to comprehensively estimate the benefit of antiviral treatment apart from virological response and adverse liver events. Meaningfully, the study findings will provide high-quality and direct evidence for optimal clinical management in such populations.
Trial registration: This trial was registered with the Chinese Clinical Trial Registry (ChiCTR2300069391) on 15 March 2023.
