What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Chronic kidney disease (CKD) is associated with the development of coronary arteries calcifications (CAC) and increased cardiovascular mortality. Previously, the investigators demonstrated that interleukin 8 (IL-8) plays a role in the calcification process, and that blockade of its receptor, CXCR2 reduces cardiovascular calcifications. The investigators hypothesize that leucocytes expressing CXCR2 may contribute to the development and progression of CAC in CKD patients. Identifying CKD patients with a high calcification phenotype and therapeutic targets to prevent cardiovascular calcifications is essential. Advanced CKD patients (stages IV and V) will undergo analysis of CXCR2 expression from neutrophils and monocytes at inclusion by flow cytometry, followed by non-contrast thoracic CT scans at inclusion, 1 year and 3 years to assess calcification scores and progression. Patients will have a pre-inclusion visit for research information and consent. If consent is given, three protocol visits (inclusion, 1 year, 3 years) including clinical exam, laboratory tests and CT evaluations will be performed.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 100 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Oct 2026

An estimate. Start dates often move.

Expected to finish

Aug 2031

An estimate. End dates often move.

Lead sponsor

Other sponsor
