About this study

Official title: An Open-label, Randomized Study to Compare the Efficacy and Safety of P1101 Plus Tenofovir Alafenamide With or Without Ursodeoxycholic Acid in Patients With Chronic Hepatitis B and Hepatitis D Virus Co-Infection

This is an open-label, randomized, multi-center study in patients with chronic HBV and HDV co-infection.

Read the detailed description

There will be 2 treatment groups in this study, 15 subjects per group as follows:

Group 1: TAF 25 mg orally (PO) QD for 60 weeks with P1101 450 µg subcutaneously (SC) Q2W add-on at treatment week 12 for 48 weeks.

Group 2: Ursodeoxycholic Acid (UDCA)* 15 mg/kg orally (PO) QD plus TAF 25 mg orally (PO) QD for 60 weeks, with P1101 450 µg subcutaneously (SC) Q2W add-on at treatment week 12 for 48 weeks.

Both groups will have a post-treatment follow-up of 24 weeks.

*: Dose of Ursodeoxycholic Acid (UDCA) will be determined by weight at Day 1 (TW0) in 2-4 divided doses.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ursodeoxycholic acid, Ropeginterferon alfa-2b and Tenofovir Alafenamide in people with Hepatitis D, run by National Taiwan University Hospital at 2 sites 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 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: status not confirmed, as of the sponsor's last update on 29 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 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?

Results are not available in the source record.

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

Contact Pei-Jer Chen (886-2-23123456 ext. 67072, peijerchen@ntu.edu.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

HDV RNA level (time frame: Week 60). 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 29 Dec 2022.
