Hepatitis A clinical trials at UCSF

The study aims to assess safety and tolerability of oral toll-like receptor (TLR) 8 agonist Selgantolimod (SLGN) administered for 24 weeks in participants with both CHB and HIV who have been receiving suppressive antiviral therapy for both viruses for ≥5 years and have qHBsAg level >1000 (3 log10) IU/mL at screening. The study will also evaluate if TLR8 stimulation with SLGN will reduce hepatitis B surface antigen (HBsAg) titers in the blood.

This is a Phase 2a, multi-center, placebo-controlled study in which patients with autoimmune hepatitis will receive zetomipzomib or placebo in addition to standard-of-care for 24 weeks; an optional open-label extension period allows patients to receive zetomipzomib (KZR-616) for an additional 24 weeks of treatment.

This is a phase 2 study in which participants with chronic hepatitis B virus (HBV) infection will receive VIR-2218, VIR-3434 and/or PEG-IFNα and be assessed for safety, tolerability, and efficacy

The investigators' research is aimed at developing more effective, finite approaches for managing individual patients with chronic hepatitis B (CHB). This prospective clinical and basic scientific study exclusively focuses on patients with the early antigen negative form of disease, which in developed countries is treated indefinitely with antiviral drugs. The investigators' study "BeNEG-DO," directly offers patients who are already taking standard oral Hepatitis B Virus (HBV) antiviral therapy for at least 192 weeks the option to stop or continue treatment. Drawing on data from pilot studies, including the investigators' own University of California, San Francisco and Sutter Institutional Review Board-approved study, the investigators will examine a finite HBV treatment strategy on clinical outcome and safety. In conjunction, the investigators will study immunologic mechanisms and gene expression profiles that correlate with and predict the post-treatment clinical course. The BeNEG-DO study could seriously question, and potentially change, the current treatment paradigm for millions of patients with CHB and also lead to new disease-terminating antiviral therapeutics.

This is an ancillary to the NIDDK-sponsored treatment trials titled: Combination Therapy of Pegylated Interferon Alfa-2a and Tenofovir Versus Tenofovir Monotherapy in Chronic Hepatitis B (NCT01369212) and Combination Entecavir and Peginterferon Therapy in HBeAg-Positive Immune-Tolerant Adults With Chronic Hepatitis B (NCT01369199). This study will examine the balance between immune regulatory and effector responses in hepatitis B-infected participants enrolled in the HBRN's clinical trials (NCT01369212 and NCT01369199) to define natural history and treatment outcome.
