About this study
Official title: A Randomized, Double-Blind, Active-Controlled Multicenter Phase 2 Study Evaluating the Efficacy and Safety of ALG-000184 Compared With Tenofovir Disoproxil Fumarate in Untreated HBeAg-Positive and HBeAg-Negative Adult Subjects With Chronic Hepatitis B Virus Infection (B-SUPREME)
This is a Phase 2 study to evaluate efficacy and safety of 48 weeks of oral once daily monotherapy with ALG-000184 versus tenofovir disproxil fumarate (TDF) for chronic HBV infection.
Read the detailed description
This is a randomized, double-blind, active-controlled, multicenter Phase 2 study to evaluate the efficacy and safety of 48 weeks of oral (PO) once daily (QD) monotherapy with ALG-000184 versus TDF in treatment naive (TN) or currently not treated (CNT) HBeAg-positive and HBeAg-negative subjects with chronic HBV infection (inclusive of chronic infection and/or chronic hepatitis).
A total of approximately 200 eligible subjects will be enrolled across 2 study parts. Part 1 will be an evaluation of HBeAg-positive subjects with chronic HBV infection and Part 2 will be an evaluation of HBeAg-negative subjects with chronic HBV infection. Each study part will consist of a main study and an exploratory liver biopsy sub-study.
Following the 48-week double-blind dosing period (Week 48), all participating subjects (in Parts 1 and 2) will be allowed to roll over into a 48 week (i.e., Week 48-96) open-label treatment extension period where they will all receive ALG-000184 monotherapy.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing ALG-000184 and TDF in people with Chronic Hepatitis B Infection, run by Aligos Therapeutics at 41 sites in 14 countries.
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 8 inclusion and 11 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: under way, not looking for participants, as of the sponsor's last update on 11 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 41 sites in China, United States, South Korea, Taiwan, Canada and 9 more countries. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
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?
HBeAg positive: HBV DNA <Lower Limit of Quantification [LLOQ] (10 IU/mL, target detected or target not detected) (time frame: 48 weeks). The study lists 2 primary outcomes in all. 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 11 Sep 2026.
