Active clinical trials for "Hepatitis, Chronic"

This is a Phase 1b/2 platform study framework to evaluate the safety and efficacy of investigational candidate(s) and their combinations as potential treatments for adults with chronic hepatitis B virus infection.

A Randomized, Double-blind, Placebo-controlled and Multicenter Phase Ⅱ Clinical Trials To Evaluate the Safety, Efficacy and Pharmacokinetics of GST-HG141 Tablets in Treated Chronic Hepatitis B (CHB) Patients With Low Viremia.

A randomized study of ALG-125755 to evaluate safety, tolerability, pharmacokinetics, and pharmacodynamics after single doses in healthy volunteers, and single and multiple doses in CHB subjects

This Phase 1b clinical study is a multi-center, open-label, dose escalation, prime only, and prime plus boost therapeutic vaccination study of 2 distinct chimpanzee adenoviral vectors (AdC6 and AdC7), containing parts of hepatitis B virus (HBV) core and polymerase antigens fused within glycoprotein D in a cohort of chronic hepatitis B (CHB)-infected adult participants who are currently receiving entecavir, tenofovir (tenofovir alafenamide fumarate or tenofovir disoproxil fumarate), or lamivudine, with documented HBV viral load suppression for at least 12 months. Approximately 24 participants will be enrolled in Group 1 and randomized to Cohort 1a or Cohort 1b. Those assigned to Cohort 1a will receive a low dose prime therapeutic vaccination of vector AdC7 on Day 1, followed by a booster vaccination on Day 91 using vector AdC6. Those assigned to Cohort 1b will receive a low dose prime therapeutic vaccination of vector AdC6 on Day 1, and will not receive a booster vaccination. Group 2 will then enroll approximately 24 participants randomized to Cohort 2a or Cohort 2b. Those assigned to Cohort 2a will receive a high dose prime therapeutic vaccination of vector AdC7 on Day 1, followed by a booster vaccination on Day 91 using vector AdC6. Those assigned to Cohort 2b will receive a high dose prime therapeutic vaccination of vector AdC6 on Day 1, and will not receive a booster vaccination. All vaccine doses will be administered by intramuscular (IM) injection. All study participants will be followed for a total of 1 year post-prime vaccination.

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.

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.

PD1 blockade has been approved as salvage therapy for advanced hepatocellular carcinoma (HCC). Although there is not solid evidence that PD1 blockade would induce hepatitis B virus (HBV) reactivation, previous clinical trials of PD1 blockade required enrolled patients to receive anti-HBV medications and control the viral load to be under 100-2000 IU/mL before initiation of PD1 blockade therapy. Such a requirement may not be necessary and could delay the treatment. Guidelines for prevention of chemotherapy induced HBV reactivation only suggest combining anti-HBV medications during the chemotherapy course without such a requirement of very load HBV viral load. The investigators hypothesized that under anti-HBV medications, patients with advanced HCC and active chronic hepatitis B virus (HBV) infection can receive durvalumab treatment without increased risks of HBV reactivation and related complications.

In Taiwan, non-cirrhosis CHB patients with mildly elevated ALT are not candidates for antiviral treatment under Taiwan NIH reimbursement criteria. Disease severity could range from mildly liver injury to cirrhosis in this group of patients. There is a substantial population of patients required antiviral treatment, but not fulfill the criteria of reimbursement treatment. For the 2 phase 3 trials of TAF, the treatment criteria of ALT were more than 2x of ULN and did not included liver biopsy as a pre-treatment assessment. In this study, CHB patient with ALT level of 1-2x ULN and significant liver injury evaluated by liver biopsy is the target study population.

This study will evaluate the efficacy and safety of PEG-IFNα alone or in combination with different dose levels of BRII-835 (VIR-2218) in participants with chronic hepatitis B virus (HBV) infection.

The goal of this clinical study is to learn more about GS-2829 and GS-6779 in healthy participants and participants with CHB.
