About this study

Official title: A Phase Ib, Double-blind, Placebo-controlled, Randomised Trial Investigating the Effect of AZD3427 on Renal Perfusion in HFrEF Patients With Renal Impairment Using Positron Emission Tomography (PET)

The present study is designed to test the effect of AZD3427 on renal perfusion in participants with heart failure and reduced eGFR (30 to 90 mL/min/1.73m2).

Read the detailed description

This is a Phase Ib randomised, double-blind, placebo-controlled, single-dose, single-centre study to evaluate the renal haemodynamic effects of AZD3427 in participants with heart failure and reduced eGFR. This study will evaluate changes in the volumetric fraction of perfused renal cortex after a single dose of AZD3427 or AZD3427 placebo. These changes will be assessed using [15O]H2O PET imaging of the kidneys. Additional endpoints include changes in total renal perfusion, plasma/serum biomarkers of renal function, and safety and tolerability. Infusion with 2 to 4 µg/kg/min dopamine/saline placebo will be used as a positive control.

Study details include:

  • The study duration will be up to 83 days.
  • The treatment duration will be 1 day.
  • The visit frequency will be on Day 1, Day 8 (± 3 days), and Day 56 (± 3 days).

What is being measured

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

  1. The volumetric fraction (%) of the renal cortex with increased perfusion from baseline to Day 8, compared to placebo.

    A PET image analysis of renal cortex measures the perfusion in approximately 8000 voxels. The volumetric fraction (%) is the fraction of voxels (%) with a positive change, i.e. increased perfusion.

    Measured: Baseline to Day 8

Secondary outcomes (3)
  1. Number of participants with adverse events (AEs)

    Number of participants with adverse events with onset after dose.

    Measured: Baseline to Day 56

  2. Number of participants with abnormal vital signs

    Predefined criteria for treatment-emergent changes in vital sign parameters will be used.

    Measured: Baseline to Day 56

  3. Number of participants with abnormal laboratory tests results

    Predefined criteria for treatment-emergent changes in laboratory parameters will be used.

    Measured: Baseline to Day 56

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AZD3427, Dopamine and Radiolabelled ligand in people with Heart Failure With Reduced Ejection Fraction (HFrEF) and Renal Impairment, run by AstraZeneca at 1 site in Sweden.

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 18 inclusion and 41 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: stopped early, as of the sponsor's last update on 24 Sep 2025. 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 Sweden. 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 was stopped early (reason given: The Sponsor encountered difficulties in recruiting patients for clinical trial D8330C00004 and decided to end the study earlier for business reasons not affecting the benefit-risk balance.). Results are not available in the source record.

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?

The volumetric fraction (%) of the renal cortex with increased perfusion from baseline to Day 8, compared to placebo. (time frame: Baseline to Day 8). 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 24 Sep 2025.
