Study of Oral TLR8 Agonist Selgantolimod on HBsAg in Participants With Both Chronic Hepatitis B and HIV
NCT05551273 · View on ClinicalTrials.gov ↗
Study Summary
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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05551273
The ClinicalTrials.gov registry entry for NCT05551273 describes a study currently listed as active not recruiting. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 29 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Allergy and Infectious Diseases (NIAID), which has 1,295 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with HIV Infections appearing as the primary indexed condition, and to 2 interventions — of which Placebo is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT05551273 reports 20 study locations spanning 12 distinct geographic areas — top geographies include Other, New York, Ohio. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
