About this study

Official title: Propylactic Use of Entecavir for Biological Agents Associated Hepatitis B Virus Reactivation in Inflammatory Arthritis Patients: a Randomized Controlled Trial

Antiviral prophylaxis can prevent the risk of biologic agents-associated HBV reactivation in hepatitis B inactive carriers and patients with past HBV infection

Read the detailed description

The risk of HBV reactivation is associated with the intensity of immunosuppression. Biological therapies block the action of biological products involved in immune-inflammatory pathogenesis of many diseases. However, these biologic agents induce a profound immunosuppression, and their use has been reported to be associated with HBV reactivation. Currently, the actual incidence of HBV reactivation in inflammatory arthritis patients who underwent biologic treatments (TNF-α blockades) is unclear, especially in inflammatory arthritis (IA) patients with past hepatitis B infection. In this study, we plan to enroll IA patients who are inactive HBV carriers (HBsAg-positive/ HBV viral loads <2000 IU/ml; subgroup 1), or have past HBV infection (HBsAg-negative/anti-HBc-positive/ HBV viral loads < 2000 IU/ml; subgroup 2); and first line biologic treatment (Humira or Enbrel or Simponi or Orencia or Mabthera or Actemra) is indicated. Patients will be randomized in a 1:1 ratio to receive either prophylactic or therapeutic entecavir treatment for each subgroup. In the prophylactic group, participants will initiate entecavir 0.5 mg/day orally one week before biologic treatment. Entecavir treatment will be continued normally for 12 months. In the therapeutic group, patients will start entecavir therapy, 0.5 mg/day orally, when reactivation of HBV (pre-emptive treatment). HBV reactivation is defined as HBV viral loads > 2,000 IU/ml for 2 consecutive visits of one month apart. The main goal of the study is to delineate the incidence of HBV reactivation during and after biologic treatment in IA patients who are inactive HBV carriers or have past HBV infection, and tries to define the optimal HBV monitoring and antiviral prophylactic strategy in IA patients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • EntecavirDrug

    Also called Baraclude

    In the prophylactic group, participants will initiate entecavir 0.5 mg/day orally one week before biologic treatment. Entecavir treatment (adjust dosage according to renal function) will be continued normally for 12 months (6 months after stopping biologic therapy or till restart another course of biologic treatment if the clinicians' judgment is minimal risk of reactivation after the first course of biologic agent treatment).

Receives: Drug: Entecavir
Control group (pre-emptive treatment)No interventionPatients will start entecavir therapy, 0.5 mg/day orally, when reactivation of HBV (defined as detectable HBV viral loads for 2 consecutive visits with at least one month apart), and continued entecavir treatment until undetectable HBV viral loads for 1 year (consistent with current APASL recommendation).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. HBV reactivation

    The main goal of the study is to delineate the incidence of HBV reactivation during and after biologic treatment in IA patients who are inactive HBV carriers or have past HBV infection, and tries to define the optimal HBV monitoring and antiviral prophylactic strategy in IA patients.

    Measured: 12 months after biologic treatment

Secondary outcomes (2)
  1. HBsAg reverse seroconversion in occult HB patients.

    Measured: 12 months after biologic treatment

  2. Hepatitis flare (ALT > 100 U/L) related to biological treatments

    Measured: 12 months after biologic treatment

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Entecavir in people with Rheumatoid Arthritis and Hepatitis B Reactivation, run by Taipei Veterans General Hospital, Taiwan at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 13 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

HBV reactivation (time frame: 12 months after biologic treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Mar 2019.
