About this study

Official title: A Phase I, Single Center, Randomized, Double-blind, Placebo Controlled, Single Dose (SD) and Multiple Dose (MD), Dose-escalation Clinical Trial to Evaluate the Tolerability and Preliminary Antiviral Activity of Therapeutic Hepatitis B Adenovirus Injection (T101) in Chronic Hepatitis B Patients

Hepatitis B virus (HBV) infection is a worldwide health problem. It has been proved that the persistence of HBV is associated with the failure to stimulate an efficient HBV-specific immune response. T101, the Chinese counterpart of TG1050, is a replication-defective adenovirus serotype 5 (Ad5) expressing multiple HBV-specific antigens (core, polymerase and envelope) and is used as therapeutic vaccine for chronic hepatitis B patients. The application of T101 aims at inducing a broad HBV-specific cellular immune response and ultimately eliminating HBV infection.

Read the detailed description

This study is a randomized, double-blind, placebo-controlled, single dose (SD) and multiple dose (MD) administration study.

Primary Objective: Safety and tolerability;

Secondary Objective:

  1. Antiviral activity of T101 (HBsAg levels).
  2. Cellular (HBV-specific) and humoral (AD5 neutralizing antibodies, NAd5) immune responses to T101.

Key Inclusion Criteria:

  1. Chronic hepatitis B patients with positive HBsAg.
  2. Patients must be receiving antiviral treatment with nucleoside analogs and have negative HBV DNA (defined as HBV DNA <20 IU/mL).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing T101 Group in people with Hepatitis B Virus (HBV), run by Tasly Tianjin Biopharmaceutical Co., Ltd. at 1 site in China.

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 13 inclusion and 20 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: finished, as of the sponsor's last update on 4 Dec 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 China. 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. Some participants in this study may receive a placebo. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Adverse events (time frame: through study completion, an average of 1 year). The study lists 6 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 4 Dec 2019.
