What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Zibotentan/DapagliflozinDrug

    Participants will receive zibotentan/dapagliflozin in fixed-dose combination as per the arms they are randomized to

  • DapagliflozinDrug

    Participants will receive dapagliflozin as per the arms they are randomized to

Study groupRoleWhat they receive
Zibotentan/Dapagliflozin dose A or Zibotentan/Dapagliflozin dose BExperimentalDrug dose (dose A or B) are determined based on eGFR values. Participants will receive daily oral dose of zibotentan/dapagliflozin in fixed dose combination.

What is being measured

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

  1. Change in eGFR from baseline

    To determine whether zibotentan and dapagliflozin in fixed dose combination is superior to dapagliflozin alone to slow decline in kidney function

    Measured: At month 24

Secondary outcomes (3)
  1. Change in Urine Albumin to Creatinine Ratio (UACR) from baseline

    To determine whether zibotentan and dapagliflozin in fixed dose combination is superior to dapagliflozin alone in reducing albuminuria

    Measured: at Month 9

  2. Time to the first occurrence of any of the components of the renal composite endpoint of 40% sustained decline in eGFR or ESKD or renal death

    To determine whether zibotentan and dapagliflozin in fixed dose combination is superior to dapagliflozin alone in reducing the incidence of the renal composite endpoint of 40% sustained decline in eGFR or ESKD or renal death

    Measured: Through study completion, approximately 38 months

  3. Change in Urine Protein to Creatinine Ratio (UPCR) from baseline

    To determine whether zibotentan and dapagliflozin in FDC is superior to dapagliflozin alone in reducing proteinuria in the biopsy-confirmed IgAN subgroup

    Measured: at Month 9

Individual data sharing
Yes: Qualified researchers can request access to anonymized individual patient-level data from AstraZeneca group of companies sponsored clinical trials via the request portal. All requests will be evaluated as per the AZ disclosure commitment: https://astrazenecagrouptrials.pharmacm.com/ST/Submission/Disclosure. Yes, indicates that AZ are accepting requests for IPD, but this does not mean all requests will be shared.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Zibotentan/Dapagliflozin and Dapagliflozin in people with Chronic Kidney Disease With High Proteinuria, run by AstraZeneca at 296 sites in 30 countries.

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 11 inclusion and 26 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: under way, not looking for participants, as of the sponsor's last update on 13 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 296 sites in United States, Japan, China, Poland, Taiwan and 25 more countries. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

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?

Change in eGFR from baseline (time frame: At month 24). 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 NCT06087835, which also lists 2 linked publications.

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 13 Oct 2026.
