Safety and Antiviral Activity of a Monoclonal Hepatitis B Antibody: a Phase 1b, Open-label Trial in Individuals With Chronic Hepatitis D Infection

Hepatitis D virus (HDV) is a major global health issue, with an estimated 12 million people living with the infection worldwide. HDV infection requires the presence of hepatitis B virus (HBV), as it relies on hepatitis B virus for replication within the liver cells. Treatment options for HDV are limited and cannot cure the infection. The combination of concurrent HBV and HDV increases the risk of developing severe liver disease, including cirrhosis and liver cancer. This risk would significantly decrease if HDV is eliminated or reduced. Consequently, there is a need for the development of new treatment options. Colleagues at Rockefeller University in New York have identified the antibody HepB mAb19, which effectively reduces the amount of circulating HBV antigens. Since HDV depends on HBV to replicate, we will test this antibody as a potential treatment for HDV. The trial design is a phase 1b open-label aiming at including 15 study participants with chronic hepatitis D infection. All study participants will receive two or three dosis of the antibody, HepB mAB19, and will be followed for 60 weeks after the first HepB mAb19 infusion. This study will evaluate the safety and pharmacokinetics of this antibody, as well as its potential effects on viral levels of HDV RNA and antiviral immune responses in individuals living with chronic HDV infection.

Once Daily Dosing of Lonafarnib Co-administered With Ritonavir for Treatment of Chronic Hepatitis D Virus Infection

Open label, single arm, multi-center clinical trial of lonafarnib 50 mg QD plus ritonavir 200 mg QD, administered orally, over a 48-week treatment period, with a 24-week post-treatment follow-up period, in patients with chronic Hepatitis D Virusinfection. Objectives: To evaluate the safety and tolerability of once daily dosing of lonafarnib 50 mg with ritonavir 200 mg over a 48-week treatment period. To evaluate the effect of once daily dosing of lonafarnib 50 mg with ritonavir 200 mg over a 48-week treatment period with a 24-week post-treatment follow-up on HDV viral levels. Trial population: Up to 30 patients with chronic HDV infection with detectable HDV RNA and compensated liver disease.

Finite Treatment of Hepatitis Delta With Bulevirtide: Identification of Biomarkers Associated With Sustained Control of HDV Infection

Finding biomarkers for stopping bulevirtide treatment of patients with hepatitis delta

Phase III Clinical Trial of Hepalatide in Patients With Chronic Hepatitis D

This study adopts a multicenter, randomized, double-blind, placebo-parallel controlled design to evaluate the efficacy and safety of L47 in the treatment of chronic hepatitis D. A total of 150 subjects are planned to be enrolled. After passing the screening, they will be randomly assigned to the L47 group or the placebo group at a ratio of 2:1, with liver cirrhosis and subjects' regional distribution as stratification factors. The two groups will receive hepratide (2.1 mg/day) or placebo, respectively. Upon completion of the 48-week double-blind treatment phase, all subjects in each group can enter the open-label treatment follow-up phase, where they may voluntarily choose to receive L47 (2.1 mg/day) treatment or undergo follow-up observation only, until week 144. Subjects who discontinue treatment prematurely during the trial may also enter the open-label treatment follow-up phase. An interim analysis will be conducted after the subjects complete 24 weeks of trial treatment, with the comprehensive response rate at week 24 as the primary endpoint. The analysis will be performed by an independent statistical team. And the interim analysis results will be reviewed by the Independent Data Monitoring Committee (IDMC) . All subjects will complete the 48-week double-blind clinical trial. Throughout the entire study period, the safety of subjects will be closely monitored and evaluated, including the monitoring of adverse events (AEs) and other safety indicators.

SOLSTICE: Combination Therapy for the Treatment of Chronic Hepatitis D Infection.

This is a phase 2 trial in which participants with chronic hepatitis D virus (HDV) infection will receive VIR-2218 and/or VIR-3434 and be assessed for safety, tolerability, and efficacy

National Cohort of Patients Co-infected With Hepatitis B and Delta Viruses

This is a multicentre observational study with prospective and retrospective data collection and retrospective data collection and biological collection from patients with HBV/HDV co-infection.
