TDF Combined With LDT for the Treatment of HBeAg-positive Hepatitis B Patients With Poor Response to TDF for 12 Months

This is an open, multicenter, exploratory and real-world clinical study. It will be carried out in patients with poor response (HBV DNA > 2x103iu / ml) to tenofovir for 12 months. After one -week screening period, patients will be randomly assigned 1:1 to control and experimental groups. The control group takes tenofovir for 12 months while the experimental group takes tenofovir combined with telbivudinefor 12months .

TDF Combined With LDT for the Treatment of HBeAg-positive Hepatitis B Patients With Poor Response to TDF for Twelve Months

Studies have shown that the HBeAg seroconversion rate of HBeAg positive chronic hepatitis B with tenofovir for one year's treatment was 17.8% and the negative conversion rate of their HBeAg and HBV DNA were 20.0% and 97.6%. The HBeAg Seroconversion rate of these patients was lower.Clinically, most patients need to take tenofovir for a long time, which may cause serious complications such as renal function damage,with decreased therapy compliance and Increased cost of treatment.In the course of tenofovir treatment, it is common that HBV-DNA negative patients with HBeAg Being down poor or staying at a low positive level for a long time keep taking the medicine. Therefore, it is Significant to Increase the HBeAg seroconversion rate of tenofovir during the clinical treatment. Telbivudine has a strong antiviral effect.Studies have shown that the HBeAg seroconversion rate of HBeAg positive CHB for one year was 25%, which was higher than other nucleosides, and it could also improve the damaged renal function to a certain extent.The HBeAg seroconversion rate of patients with poor response to tenofovir for 12 months could be still poor if for 24 months . Therefore, this study is to observe the efficacy of these patients combined with telbivudine.
