What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This observational study examines kidney tissue from adults with diabetic kidney disease who are already having a kidney biopsy or surgery as part of their regular care. Researchers want to see if people taking SGLT2 inhibitors (a type of diabetes medicine) show different biological patterns in their kidney tissue compared to those not taking them. The goal is to understand how these medicines may protect the kidneys and link those patterns to changes in kidney function over time.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
SGLT2 inhibitors (a type of diabetes medicine)
What this could lead to
If successful, this study could reveal how SGLT2 inhibitors protect the kidneys, pointing toward better treatments for diabetic kidney disease.
What could go wrong
This is an observational study, not a controlled trial, so it cannot prove cause and effect. Results may not apply to everyone with kidney disease.

Participants

About 200 people

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

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

TRIDENT 2.0 will enroll approximately 200 participants across multiple sites. Eligible participants include: * Patients with diabetic kidney disease (DKD) confirmed by clinically indicated biopsy. * Patients with other kidney diseases (disease controls). * Living kidney donors (donor biopsy tissue). * Patients undergoing nephrectomy (non-tumor, adjacent normal tissue when available). All participants must provide informed consent for release of one H\&E slide from their clinical biopsy or surgical specimen and for abstraction of relevant clinical data.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥18 years * eGFR ≥10 ml/min/1.73 m2 based on the 2021 race-free CKD-EPI equation13 * Underwent a clinically indicated kidney biopsy, living donor biopsy, or nephrectomy (non-tumor adjacent tissue available). * Able and willing to provide informed consent for release of one pathology and clinical data abstraction. Exclusion Criteria: * Inability to provide informed consent. * Archived biopsy or surgical tissue unavailable for slide preparation. * Any local institutional policy that prohibits release of H\&E slides for research.
