About this study

Official title: A Single Dose, Non-Randomised, Open-Label, Parallel-Group Study to Investigate the Pharmacokinetics, Safety, and Tolerability of Zibotentan in Healthy Participants Compared to Participants With Moderate Hepatic and Moderate Renal Impairment

This study will evaluate the pharmacokinetics (PK), safety, and tolerability of a single oral dose of zibotentan in patients with moderate hepatic and moderate renal impairment in comparison to a matched healthy control group.

Read the detailed description

This is a single-dose, non-randomised, open-label, parallel-group study.

All participants will receive a single oral dose of 5 mg zibotentan under fasted conditions and will be involved in the study for approximately 5 weeks.

Approximately 12 participants will be enrolled into each one of the 2 cohorts and receive the study intervention:

  • Cohort 1: 12 participants with moderate hepatic impairment and moderate renal impairment as assessed at Screening
  • Cohort 2: 12 healthy participants matched for age (± 10 years), gender, and BMI (± 20%) on a group level to participants in Cohort 1

The study will comprise of the following study periods:

  • A Screening Period of maximum 28 days (before dosing): participants will be screened for eligibility.
  • A Residential Period of 8 days: participants will be admitted to the study centre in the evening on Day
  • 2, two days before administration of a single oral dose of zibotentan (Day 1). Participants will have final study assessments on Day 6 (120 hours post-dose) and will be discharged that day.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Zibotentan in people with Hepatic Impairment and Renal Impairment, run by AstraZeneca at 1 site in Bulgaria.

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 24 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 27 Jan 2022. 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 Bulgaria. 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 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?

Area under plasma concentration-time curve from time zero to infinity (AUCinf) (time frame: Day 1 to Day 6). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05112419, which also lists 1 linked publication.

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 27 Jan 2022.
