Participants who received at least one dose of PBGENE-HBV will be enrolled in this LTFU study.
This is a LTFU observational study designed to evaluate the safety of PBGENE-HBV in participants previously exposed to PBGENE-HBV. This study protocol does not include administration of PBGENE-HBV.
895 studies on the registry are indexed under Hepatitis B, Chronic; 151 are open to participants now.
This study's planned enrollment of 45 is below the median of 400 across 206 observational studies indexed under Hepatitis B, Chronic.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Started Dec 2025 (actual). Primary completion is estimated for Jan 2040, 169 months after the start.
Of 71 observational studies under Hepatitis B, Chronic, half reached primary completion within 55 months of starting (the median), counting those still running; a quarter within 31 and three quarters within 99. This study's planned 169 months is above that.
