A Trial to Evaluate the Efficacy and Safety of WGc0201 in Patients With Chronic Hepatitis B Virus Infection

Q: Who can participate in NCT07051187?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

Q: How do I contact the trial site for NCT07051187?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Q: Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.

An Open-Label, Single-Arm, Dose-Escalation Phase I Clinical Trial to Evaluate the Efficacy and Safety of WGc0201 in Patients With Chronic Hepatitis B Virus Infection

A Trial to Evaluate the Efficacy and Safety of WGc0201 in Patients With Chronic Hepatitis B Virus Infection (NCT07051187) is a Phase 1 interventional studying Chronic Hepatitis B Virus (Hbv), sponsored by Jiyan Liu. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

Existing nucleoside analogues (NAs) and interferon therapy for chronic hepatitis B (CHB) have limitations, including drug resistance, low HBsAg clearance rates, and irreversible immunosuppression. Therapeutic vaccines, by activating virus-specific T cells and B cells, hold promise for achieving functional cure (HBsAg clearance + sustained HBV DNA negativity). This study is an open-label, single-arm, dose-escalation Phase I clinical trial. The study population consists of patients with chronic hepatitis B virus infection who have achieved virological stability following standard antiviral therapy. Phase I (dose exploration): three dose groups, with three patients per group. The primary objective is to observe and evaluate the safety of the WGc0201 vaccine in the study population (incidence and severity of adverse events).

What Stage of Research Is This?

Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Chronic Hepatitis B Virus (Hbv), a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 9 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.
