Study summary

This is a single-center, prospective, exploratory clinical study. The study plans to enroll 30 chronic hepatitis B (CHB) patients which achieved HBsAg clearance based peginterferon α-2b treatment. Eligible subjects will receive either 12-24 weeks interferon consolidation therapy (180μg administered subcutaneously in the abdomen or thigh once weekly) or not according to physician's recommendation and patient's preference, with regular follow-up for HBV recurrence. Patients will be followed up every 12 weeks. The study will evaluate changes in intrahepatic covalently closed circular DNA (cccDNA) and peripheral blood HBV pregenomic RNA (pgRNA) levels after achieving HBsAg clearance.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Voluntarily enroll in the study, able to understand and voluntarily sign the form;
  • Aged 18-65 years (inclusive), no gender restriction;
  • A history of positivity for at least 6 months or other evidence suggesting chronic hepatitis B;
  • First observed clinical cure after treatment with peginterferon α-2b (PegIntron®), either as monotherapy or in combination with NAs, defined as serum HBsAg negative (\<0.05IU/ml), HBV DNA undetectable (HBV DNA\<20IU/ml), and HBeAg negative, within a 4-week window from the first observed day of clinical cure at the time of screening;
  • Agreement to undergo two liver during the study;
  • Negative pregnancy test within 24 hours before the first liver biopsy (for childbearing-age females); and subjects (both male and female) should use effective during the study period.

Exclusion criteria

Exclusion Criteria:

  • Lactating women;
  • Evidence of acute severe liver injury: such as > 10 , or significantly elevated ALT with significantly elevated ;
  • Evidence of decompensated liver disease: such as ascites, esophageal varices rupture bleeding, sepsis, hepatic encephalopathy, hepatorenal syndrome, etc.; or history of decompensated cirrhosis;
  • Evidence of hepatocellular carcinoma;
  • (PT) or INR > ULN;
  • Participation in other interventional trial studies within 3 months before screening or other conditions deemed unsuitable for inclusion by the investigator.
Terms in these criteria, in plain language(8)

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.

Informed consent

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.

Hepatitis B tests

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.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Apr 2025; primary completion for Dec 2027, 32 months later.

Of 42 interventional studies with no phase under Hepatitis B, Chronic, half reached primary completion within 44 months of starting (the median), counting those still running; a quarter within 21 and three quarters within 121. This study's planned 32 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 9, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
