Conditions

Hepatitis B Virus, Liver Transplant

Brief summary

This clinical study aims to evaluate the efficacy and safety of switching to entecavir orally disintegrating tablets (ETV-ODT) in liver transplant recipients with chronic hepatitis B, with a particular focus on the impact of the conversion on renal function. After providing written informed consent, participants will undergo screening assessments to determine eligibility based on the inclusion and exclusion criteria. Eligible participants who receive the investigational product will visit the study site at predetermined time points over a 48-week period to complete the scheduled study procedures.

Detailed description

This study aims to evaluate the antiviral efficacy, safety, and potential improvement in medication adherence after converting stable liver transplant recipients to Entecabell ODT. Only participants who meet all inclusion and exclusion criteria will receive the investigational product. After conversion, participants will take Entecabell ODT 0.5 mg once daily for 48 weeks and will be followed according to the scheduled visits and assessments. The primary objective of the study is to assess the impact of switching from entecavir tablets to Entecabell ODT on renal function in liver transplant recipients receiving entecavir for HBV prophylaxis. Secondary objectives include evaluating the antiviral effect against HBV and the potential improvement in medication adherence following conversion to Entecabell ODT.

Interventions

DRUGEntecavell ODT

Exclusion criteria

1. Patients who have undergone transplantation of organs other than the liver or re-transplantation. 2. Patients who have received bioartificial liver system treatment or auxiliary partial orthotopic liver transplantation (APOLT) before the transplantation. 3. Patients with concurrent viral infections (HCV, HIV). 4. Patients with eGFR \<30 or those undergoing dialysis 5. Pregnant or breastfeeding women. 6. Patients or their spouses/partners who do not agree to use medically acceptable and appropriate contraception methods\* during the clinical trial period. \* Appropriate contraception methods: hormonal contraception, intrauterine device (IUC or IUS), tubal ligation, tubal occlusion, hysterectomy, vasectomy, double barrier methods (combined use of male or female condoms with cervical caps, diaphragms, or contraceptive sponges), single barrier methods with spermicide. 7. Patients with a history of hypersensitivity to Entecavir. 8. Patients who are deemed unsuitable for participation in the clinical trial by the investigator.
