What this trial studies

This observational study aims to evaluate the satisfaction and adherence of chronic hepatitis B patients who switch from entecavir therapy to tenofovir alafenamide (TAF). TAF is known for its convenience, requiring no dietary restrictions and less frequent dosage adjustments compared to entecavir. The study will assess improvements in patient satisfaction and adherence, as well as the efficacy of TAF therapy through changes in novel biomarkers like HBV core-related antigen. The goal is to determine if switching to TAF can enhance treatment outcomes for patients dissatisfied with their current therapy.

Who should consider this trial

Good fit: Ideal candidates are adults over 20 years old with chronic hepatitis B who are currently on entecavir therapy and are dissatisfied with its efficacy or convenience.

Not a fit: Patients with end-stage renal disease, active malignancies, or those co-infected with other viruses may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve patient satisfaction and adherence to hepatitis B treatment, leading to better health outcomes.

How similar studies have performed: Previous studies have shown positive outcomes with TAF in chronic hepatitis B treatment, suggesting this approach may be beneficial.
