Filter by:This is a multicenter, randomized, open-label control trial of two arms conducted at 10 centres in China.The aim was to investigate whether sequential combination therapy with Thymosin alpha 1 and entecavir is superior to continuous ETV monotherapy in HBeAg-positive chronic hepatitis B patients with previous long-term entecavir therapy (≥ 2 years), and to select the optimal patients who may benefit from sequential combination therapy.
Chronic hepatitis B(CHB) is a common infectious disease affecting up to 2 billion people worldwide. Around 650 thousand people died of liver failure, cirrhosis and primary liver cancer caused by chronic hepatitis B every year. Age is the main factor affecting the chronicity of hepatitis B, while 90% and 25% to 30% of hepatitis b virus(HBV) infection in perinatal and infant period will develop into chronic infection respectively. Whereas the proportion in patients above 5 years old is only 5% to 10%. Intestinal microbiota plays an important role in maintaining normal physiological function of the intestine and the immune function of the body. It has been found that the disorder of intestinal microbiota is associated with numerous intestinal and parenteral diseases. Intestinal microbiota transplantation(IMT) is a significant method to reconstruct intestinal flora. Recently, the relationship between immune response and intestinal microbiota has been claimed. In a previous study using IMT to treat HBeAg positive chronic hepatitis B patients combined with antiviral therapy, 80% of them has reached HBeAg clearance. The investigators propose a randomised trial of IMT in patients with chronic hepatitis B combined with antiviral therapy. The investigators will assess the serum HBsAg, anti-HBs, HBeAg, anti-HBe, anti-hepatitis B core antigen, the relief of gastrointestinal symptoms, and the fecal microbiota before and after IMT. Patients will be randomized to either antiviral therapy or IMT combined antiviral therapy over a 26 weeks period.
Chronic HBV infection is major problem in Asian countries. Years after chronic infection, in some cases serum HBsAg level declines to unmeasurable level. Some of patients develop anti-HBsAb but there is no standard treatment to accelerate HBsAg seroconversion. There is a study to determine efficacy and safety of HBV vaccine in who is Chronic HBV infection and lost their HBsAg without seroconversion to anti-HBsAb.
The aim of the prospective real-world study is to evaluate whether sequential combination therapy with pegylated interferon plus entecavir/tenofovir could induce higher rates of HBsAg loss in nucleoside-treated patients with chronic hepatitis B compared to continuous nucleoside treatment.
In Chronic hepatitis B (CHB) patients receiving long-term sequential Neucleos(t)ides(NAs), majority of these CHB patients experienced drug resistance and switched to Tenofovir disoproxil fumaratate(TDF). However, some of patients on long term TDF experienced impairment of renal function and bone mineral density. After Tenofovir alafenamide(TAF) was in clinical practice, these group of patients got an clinical option to switch from TDF to TAF. The investigators designed a prospective cohort study to evaluate the real life effectiveness and safety in participants with chronic HBV infection switch from TDF to TAF vs. maintaining on TDF.
The current study is a prospective, randomized, open, multi-center investigation. The aim of current study is to investigate whether the Recurrence-free Survival Rate (RFS）of the hepatitis B related -hepatocellular carcinoma subjects who have been treated by resection can be improved by peginterferon alfa-2a
This is a nonrandomized, open-label, no-control, dose-escalation Phase 1b trial in 18 patients with chronic HBV infection to determine the safety, preliminary efficacy, and pharmacokinetics (PK) of QL-007 after administration over 28 days of multiple oral doses in a fasted state at the following planned dose levels: 200 mg/day (100 mg two times a day (BID)), 400 mg/day (200 mg BID), then 600 mg once daily (QD), with 6 patients for each cohort.
The majority of childbearing age women with hepatitis B virus infection were still in the immune tolerance period. Our recent research had shown that most puerperae after delivery had elevated ALT level. However, there is no withdrawal time recommendations after childbirth at present.Through the study of hepatitis occurrence after delivery and drug withdrawal, the investigators explore the withdrawal time of antiviral treatment during pregnancy.
Pregnant women carry high HBV DNA loads before delivery, which is the most important factor leading to mother-to-child transmission of HBV. Nucleoside analogue antiviral treatment during late pregnancy can significantly reduce the incidence of HBV MTCT, but security problems of using NA treatment during pregnancy has not been eliminated, Therefore, the aim of our study is to explore the effect of starting to use Tenofovir Disoproxil Fumarate(TDF) antiviral treatment from the 32 weeks of gestation to block mother-to-child transmission of hepatitis B virus(HBV MTCT).
CR-HepB registry started in June 30,2012 to collect HBV cases from general hospitals or specialized hospitals for infectious diseases in mainland China. Demographics, diagnosis, laboratory test results, family history and prescriptions were recorded. The main criteria for registration is HBsAg-positivity more than 6 months, and these patients will receive followed-up visits every three to six months.
