Can sugar in urine predict kidney drug success?
NCT ID NCT07084038
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study follows 300 adults with chronic kidney disease who are already taking SGLT2 inhibitors. Researchers want to see if the amount of sugar in their urine is linked to changes in protein levels, a key marker of kidney damage. The goal is to find a simple way to tell if the drug is working well and possibly adjust doses for better results.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- SGLT2 inhibitor
- What this could lead to
- If successful, this could help doctors personalize SGLT2 inhibitor doses for better kidney protection in chronic kidney disease.
- What could go wrong
- This is an observational analysis, not a treatment trial. It may not lead to direct changes in care, and results may not apply to all patients.

This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Patients aged ≥18 years diagnosed with chronic kidney disease (CKD) at the First Medical Center of the PLA General Hospital by March 2026, who regularly received oral administration of standard-dose SGLT2 inhibitors (SGLT2i), will be included. Medical records and laboratory test results (including routine blood tests and blood biochemical parameters) will be collected. Changes in 24-hour urinary glucose and urinary protein levels from baseline will be observed at 3 and 6 months after SGLT2i administration.

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. Patients with a confirmed diagnosis of chronic kidney disease (CKD). Currently receiving stable, standard-dose SGLT2i therapy at screening. Proteinuria ≥0.15 g/24 h (or urine protein-to-creatinine ratio \[UPCR\] ≥440 mg/g or urine albumin-to-creatinine ratio \[UACR\] ≥300 mg/g) at screening. Estimated glomerular filtration rate (eGFR) ≥15 mL/min/1.73m² calculated by the CKD-EPI creatinine equation at screening. Willing and able to provide written informed consent. Exclusion Criteria: Discontinuation of SGLT2i during the follow-up period. History of symptomatic hypotension (systolic blood pressure\<90 mmHg) without antihypertensive medication, or current hypotensive episode at screening. Unstable renal function (e.g., acute kidney injury or rapidly progressive glomerulonephritis with a \>50% decline in eGFR within 3 months prior to screening). Use of corticosteroids or having an indication for corticosteroid therapy within the past 6 months. Receipt of immunosuppressive therapy or having an indication for immunosuppressive therapy within the past 6 months. History of intolerance to SGLT2 inhibitors. History of ketoacidosis within the past 5 years.
