Study summary

The current study aims to investigate and compare the anti-inflammatory effects of melatonin versus folic acid in patients with diabetic nephropathy.

Read the detailed description

Diabetes mellitus (DM) is a metabolic disorder characterized by chronic hyperglycemia, resulting from either insufficient insulin production (Type I) or ineffective insulin utilization (Type II).

Melatonin, a hormone produced by the pineal gland, regulates circadian rhythms and exhibits strong antioxidant, anti-inflammatory, and immunomodulatory properties.

Folic acid, a B-vitamin essential for cell division and DNA synthesis, also exerts antioxidant effects and supports endothelial function by lowering plasma homocysteine levels.

Inclusion criteria

  • Adults aged 18-75 years.
  • Patients with a confirmed diagnosis of Type 2 diabetes and diabetic nephropathy, as indicated by an elevated urine albumin-to-creatinine ratio (UACR ≥ 30 mg/g) or a decreased estimated (eGFR \< 60 mL/min/1.73 m²).

Exclusion criteria

Exclusion Criteria:

  • Patients who are expectant or breastfeeding.
  • Have significant comorbidities.
  • Have rapidly declining renal function.
  • Have acute kidney injury.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

What researchers measure

Primary outcomes

  1. Change in the urine albumin-to-creatinine ratio (UACR)

    Change in the urine albumin-to-creatinine ratio (UACR) will be recorded. The UACR is an important biomarker of kidney impairment because it measures the quantity of albumin discharged in the urine in relation to creatinine levels. Elevated UACR readings (≥ 30 mg/g) indicate albuminuria, a symptom of diabetic nephropathy.

    Time frame: 12-week after treatment

Secondary outcomes

  1. Change in the estimated glomerular filtration rate (eGFR)

    Change in the estimated glomerular filtration rate (eGFR) will be recorded. eGFR, which estimates the kidneys' filtering ability based on serum creatinine levels, age, sex, and race. A low eGFR (less than 60 mL/min/1.73 m²) may suggest chronic renal damage caused by diabetes.

    Time frame: 12-week after treatment

  2. Change in the serum creatinine

    Change in the serum creatinine level will be recorded. Serum creatinine is a waste product produced by muscle metabolism, and excessive levels suggest poor kidney function, since the kidneys may struggle to filter waste properly.

    Time frame: 12-week after treatment

  3. Change in the neutrophil gelatinase-associated lipocalin (NGAL)

    Change in the neutrophil gelatinase-associated lipocalin (NGAL) will be recorded. Neutrophil gelatinase-associated lipocalin is a protein produced by the kidneys in response to injury or damage, and increased levels are related with both acute kidney injury (AKI) and chronic kidney disease (CKD).

    Time frame: 12-week after treatment

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Apr 2025 to primary completion in Jul 2026, 15 months.

Of 49 non-industry interventional studies with no phase under Diabetic Nephropathies, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 37. This study's 15 months is below that.

Counting every sponsor, half of 50 studies reached it within 23 months; a quarter within 11 and three quarters within 37.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 17, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
