About this study

Official title: A Study to Evaluate the Pharmacokinetics and Safety of Anaprazole Sodium in Subjects With Hepatic or Renal Impairment and in Elderly Subjects

The objective of this study is to evaluate the pharmacokinetic profile and safety of anaprazole sodium in adult subjects, particularly including the elderly and those with renal or hepatic impairment.

Read the detailed description

This study is a single-center, open-label, single-dose trial designed to assess the pharmacokinetics and safety of anaprazole sodium in adult subjects. The study consists of five groups: healthy volunteers, subjects with moderate hepatic impairment, subjects with moderate renal impairment, subjects with severe renal impairment, and elderly subjects. Each arm will enroll 8-12 subjects, for a total target sample size of 40-60. The overall trial schedule consists of a Screening Period (Day -14 to Day -2), a Baseline Period (Day -1), a Dosing/Study Period (Day 1 to Day 3), and a Safety Follow-up Period (Day 7). Blood samples for pharmacokinetic (PK) analysis will be collected from all subjects throughout the study. In addition, urine samples for PK assessment will be collected specifically from subjects in the healthy control group and the moderate and severe renal impairment groups.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Anaprazole Sodium enteric-coated tablet in people with Hepatic Insufficiency and Renal Insufficiency, run by Xuanzhu 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 9 inclusion and 48 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: opening soon, as of the sponsor's last update on 16 Jan 2026. 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. 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?

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?

Contact Hong Zhang, PhD (+86-13654376192, jhongzhang@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cmax (time frame: Up to 48 hours from anaprazole sodium administration). The study lists 7 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 16 Jan 2026.
