Filter by:This study was a retrospective clinical observational cohort study. All patients with chronic hepatitis B (CHB) whose HBsAg decreased by less than 10% were treated continuously with interferon in the Department of Hepatology, Beijing Ditan Hospital, Beijing Medical University, Beijing Capital University, 2008.10-2017.4. The total interferon treatment time of the enrolled subjects was 48 weeks. The subjects were randomly divided into the following two observation cohorts: 1) patients with chronic hepatitis B treated with continuous interferon for 48 weeks; 2) intermittent interferon For 48 weeks of treatment for patients with chronic hepatitis B, the interferon treatment interval was 3 months. HBV DNA content, HBsAg/anti-HBs, HBeAg/anti-HBe and biochemical markers, serum AFP and liver imaging (liver ultrasound) were collected before treatment (baseline) and during treatment. The primary outcome measure was the rate at which HBsAg disappeared at 48 weeks of treatment. The secondary evaluation index was the 48-week HBeAg seroconversion rate. To investigate the efficacy, influencing factors and safety of interferon intermittent treatment of chronic hepatitis B.
This randomized controlled trial is designed to evaluate safety, effectiveness and pharmacokinetic-pharmacodynamic (PK/PD) relationships associated with three different Nitazoxanide (NTZ) treatment regimens added to Tenofovir Disoproxil Fumarate (TDF), Tenofovir Alafenamide (TAF) or Entecavir (ETV) in treating Chronic Hepatitis B (CHB).
A single-center, open-Label, randomized, single-dose, two-period, two-sequence, crossover study to assess the bioequivalence of test formulation entecavir tablets 1.0 mg with reference formulation entecavir tablets (Baraclude®) 1.0 mg in healthy adult subjects under fasting conditions.
HBeAg-negative chronic hepatitis B (CHB) patients with low Level HBsAg were enrolled. After giving informed consent, patients were treated with nucleoside analog(s) (NAs) once a day and weekly subcutaneous injections of peginterferon alfa-2a 180 micrograms/week or peginterferon alfa-2b 180 micrograms/week for 12 weeks. At week 12, the decrease of HBsAg was evaluated. ①If the decrease of HBsAg is more than 50% compared to baseline level. NAs was stopped, patients were treated with weekly subcutaneous injections of alfa-2a 180 micrograms/week or peginterferon alfa-2b 180 micrograms/week. Treatment endpoint was HBsAg loss(＜0.05 IU/ mL). Depending on the decline of HBsAg level, treatment was either continued for a prolonged period (no more than 96 weeks) until the endpoint was achieved, or terminated in week 96. After treatment, all patients were followed up for 48 weeks. ②If the decrease of HBsAg is less than 50% compared to baseline level. The combination therapy of NAs and peginterferon alfa was extended to week 24. Then, the decrease of HBsAg was evaluated again. If the decrease of HBsAg is more than 50% compared to baseline level. NAs was stopped, patients were treated with weekly subcutaneous injections of alfa-2a 180 micrograms/week or peginterferon alfa-2b 180 micrograms/week. Treatment endpoint was HBsAg loss(＜0.05 IU/mL). Depending on the decline of HBsAg level, treatment was either continued for a prolonged period (no more than 96 weeks) until the endpoint was achieved, or terminated in week 96. After treatment, all patients were followed up for 48 weeks. If the decrease of HBsAg is less than 50% compared to baseline level. Peginterferon alfa was stopped, patients were treated with NAs once a day and then followed up for 48 weeks. Patients who maintained the original NAs treatment served as a control group.
To Identify the collected cases who can stop NAs safely with satisfactory clinical outcome including sustain viral remission and HBsAg clearance among chronic hepatitis B(CHB) patients.
Open-label, extension study to evaluate the safety and efficacy of combination therapy and its effect on sustained viral response biomarkers.
A total of 2000 chronic hepatitis B (CHB) patients with liver biopsy performed at least 1 year after antiviral therapy are enrolled. All the patients will receive original antiviral treatment for the following 10 years. Patients will be assessed at baseline and at every six months for blood count, liver function test, alpha fetoprotein (AFP), prothrombin time, liver ultrasonography, liver stiffness measurement (LSM), Hepatitis B virus (HBV) DNA and HBV serological markers. HBV-related endpoint events, including cirrhosis decompensations (ascites, esophageal variceal bleeding and hepatic encephalopathy), hepatocellular carcinoma (HCC), liver transplantation and liver-related death, will be collected during follow-up.
This is a randomized, open-label, positive-control, dose-escalation Phase 1b trial in 60 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, 400, and then 600 mg.
Treatment with Tenofovir Alafenamide(TAF) in Chronic Hepatitis B (CHB) patients classified as beyond treatment indication of current international guidelines (e.g. aged more than 40 years old and 4 ≤ log HBV-DNA IU/mL < 8) is expected to bring improvement in long-term clinical outcomes. This expected result may expand the treatment indications in patients with CHB based on age and HBV-DNA in contrast to current international guidelines of CHB.
This study is a multi-center, prospective, real-world study, males and non-pregnant, non-lactating female HBeAg positive or negative patients (above 18 years of age) who were mono-infected with HBV, either NA treatment-naïve or treatment-experienced, but TAF naïve will be enrolled in this study, and they will be treated with TAF, alone or in combination with other HBV antivirals. During 36 months of treatment, efficacy and safety will be evaluated.
