About this study

Official title: A Phase I, Double-blind, Randomized, Placebo-controlled, Dose Escalating Study to Evaluate the Safety, Immunogenicity and Efficacy of YS-HBV-002 in the Treatment of Chronic Hepatitis B (CHB) Infection in Adults ≥ 18 Years Old

This is the first-in-human Phase I, double-blind, randomized, placebo-controlled, dose escalating study to evaluate the safety, immunogenicity and preliminary efficacy of the YSHBV-002 in the treatment of CHB in adults ≥18 years old. There will be 3 escalating doses of YS-HBV-002 to be administered intramuscularly: 0.5mL, 1.0mL, and 2.0mL.

Read the detailed description

This is the first-in-human Phase I, double-blind, randomized, placebo-controlled, dose escalating study to evaluate the safety, immunogenicity and preliminary efficacy of the YSHBV-002 in the treatment of CHB in adults ≥18 years old. There will be 3 escalating doses of YS-HBV-002 to be administered intramuscularly: 0.5mL, 1.0mL, and 2.0mL. Enrollment in the study will sequentially start from the low dose 0.5mL as Group A, then to the mid-dose 1.0mL as Group B and lastly to the high dose of 2.0mL as Group C. Each group will have 16 patients enrolled. The first 4 enrollees in Group A will be sentinel patients and will be allocated at a 1:1 ratio to receive 0.5mL of either YS-HBV-002 or placebo (Table 3). As there is no comparable equivalent to YS-HBV-002 available in the market, the placebo of normal saline solution to be injected intramuscularly will serve as the control in this trial. The next 12 enrollees in Group A will be the main patients and will be allocated at 5:1 to receive 0.5mL of either YS-HBV-002 or placebo. The vaccination regimen will be 1 IM injection every 3 days in the deltoid muscle, alternately for approximately 6 weeks. A total of 14 injections will be administered to each patient.

What is being measured

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

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing YS-HBV-002 in people with Chronic Hepatitis B, run by Yisheng Biopharma (Singapore) Pte. Ltd. at 1 site in Philippines.

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 10 inclusion and 21 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: stopped early, as of the sponsor's last update on 24 Feb 2025. 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 Philippines. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study was stopped early (reason given: Business strategy). 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?

Incidence of AEs within 30 minutes after vaccination. (time frame: 30 minutes post each vaccination). The study lists 4 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 24 Feb 2025.
