Active clinical trials for "Hepatitis B"

The primary objective of this study is to evaluate hepatitis B surface antigen (HBsAg) loss and seroconversion in participants who stop tenofovir disoproxil fumarate (TDF) (Stop TDF arm) compared to participants who continue TDF (Continue TDF arm). Only participants who already are on treatment with TDF monotherapy or TDF in combination with lamivudine or emtricitabine for at least 4 years and who achieved and maintained virologic suppression (< 400 copies/mL) for 3.5 or more years will be included in this study. One treatment arm will stop the TDF therapy while the other treatment arm will continue the TDF therapy. Participants in the Stop TDF arm will be monitored very closely with special focus on biochemical flares (especially alanine aminotransferase (ALT) increases) and virological relapses (Hepatitis B viral load increases). If any participant in the Stop TDF arm exceeds one or more predefined limits for such flares or relapses, TDF treatment will be reinstituted.

The purpose of this study is to investigate whether it is possible to augment the response of patients with HBeAg-positive chronic hepatitis B to entecavir by using a temporary peginterferon alpha-2a add-on strategy

This study will evaluate HIV-HBV infected individuals who have evidence of HBV replication in the blood after taking 48 weeks of more of the HBV active medication tenofovir in combination with emtricitabine or lamivudine. Eligible participants will be randomized to receive 24 weeks of entecavir (ETV) 1 mg versus continued standard of care antiretroviral therapy. After 24 weeks, individuals on entecavir or who remain HBV viremic on standard of care will receive ETV o for an additional 24 weeks. The hypothesis is that intensification with entecavir will reduce HBV DNA at 24 weeks more than continued antiretroviral therapy without entecavir.

This study will evaluate the use of telbivudine for patients with HBeAg-positive CHB with an option to intensify treatment at Week 24 by adding tenofovir for patients who do not achieve HBV DNA non-detectability.

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 was a non-blinded, prospective clinical study. From June 2020 to October 2021, 254 patients with HBV-ACLF were treated at the Department of Infectious Diseases, Xiangya Hospital, Central South University (Changsha, China). 186 patients who met the enrollment criteria were included in this study. Inclusion criteria were as follows: (1) aged 18-65 years old; (2) patients with ACLF caused by HBV infection; (3) meeting the diagnostic criteria for ACLF by the Asian Pacific Association for the Study of Liver (APASL).The exclusion criteria were as follows: (1) pregnancy or lactation; (2) previous liver transplantation; (3) hepatocellular carcinoma or other malignancy; (4) human immunodeficiency virus(HIV) infection or other immunocompromised states; (5) complicated with underlying diseases such as severe heart, respiratory, and blood system diseases. Based on the inclusion and exclusion criteria, the investigators randomly matched patients at a 1:1:1 ratio to three groups whose age, sex ratio, complication, and liver function were comparable: comprehensive medical treatment (Control group), PE group, and DPMAS plus half-dose sequential PE (DPMAS + PE group). As a result, 62 subjects per group were recruited into the study. This study was approved by the Clinical Research Ethics Committee of Xiangya Hospital, Central South University with informed content obtained from all participants (No. 202201022). The study protocol followed the principles of the Helsinki Declaration strictly. All the 186 patients enrolled received comprehensive medical treatment after admission to the hospital, including anti-viral treatment, general supportive treatment, supplementation of blood products, such as albumin and plasma, and symptomatic treatment.

Randomized, double blind parallel group, positive control, multi-center trial. Patients will be randomized at 1:1 ratio in group A or group B

The objective of this study is to provide open label emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) for an additional 5 years (240 weeks) to adults completing study GS-US-203-0107.

The purpose of this trial is to prove that the strategy of treatment adjustment at W24 according to virological response based on ROADMAP concept is better than standard of care strategy.

Data for stool microbiome will be collected for all the chronic hepatitis B subjects (pre cirrhotic,compensated,decompensated and reactivation). All the in and out patient with Hepatitis B reactivation will be recruited and randomized into two arms. Group 1 Tenofovir Group 2 Tenofovir with FMT (Fecal Microbiota Transplant). Tenofovir would be given 300 mg once daily FMT through NJ (Naso-Jejunal) tube for 7 days.
