About

Chronic hepatitis B (CHB) is an important public health problem in the world. There are still more than 250 million chronic hepatitis B virus (CHB) infected people in the world. Its preventive effect has reached a relatively ideal effect, but its therapeutic effect still has great room for improvement.

Tenofovir(TDF) is the first-line antiviral treatment with good clinical efficacy. However, some patients who take TDF for a long time have different degrees of renal dysfunction, which limits the use of TDF in these patients.

Tenofovir Alafenamide Fumarate (TAF) has better plasma stability and stronger liver targeting, and reduces the side effects of renal function damage and bone mineral density reduction. Telbivudine (LDT), a nucleoside analogue, has the advantages of rapidly reducing HBV viral load and high HBeAg seroconversion rate.

In addition, prospective studies have shown that LDT can improve the estimated glomerular filtration rate (EGFR).Therefore, this study aims to explore the clinical study of LDT combined with TDF and TAF in patients treated with tenofovir and EGFR < 90ml / min / 1.72m².

Full description

This is a multi-center, open-label clinical study. This study was aimed to explore the LDT combined with TDF and TAF in patients treated with TDF and EGFR < 90ml / min / 1.72m².The primary objectives of this study is as follows: To access the effectiveness and safety of 12-month treatment with LDT combined with TDF and only TAF in patients with CHC and cirrhosis in real-world clinical practice in Southern area of China. The proportion of participants with HBV DNA (DNA:Hepatitis B virus deoxyribonucleic acid)was evaluated. This study aims to enroll 200 patients with CHB in each treatment group. Patients with CHB having received the TAF previously but EGFR < 90ml / min / 1.72m² subsequently fulfills the indication of antiviral therapy will be administered with LDT combined with TDF and only TAF treatment. After 12-month treatment, all the patients will be followed up for 12 months.
