Sleep hormone may shield kidneys from antibiotic harm
NCT ID NCT05084196
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether melatonin, a common sleep aid, can prevent kidney damage in hospitalized patients who need a strong antibiotic called vancomycin. About 300 adults aged 18 to 75 will receive either melatonin or a placebo alongside their antibiotic. The goal is to see if melatonin reduces the risk of acute kidney injury, a serious side effect of this treatment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion criteria: * Aged 18 to 75 years * Currently prescribed vancomycin with the presumption that therapy will be continued for at least 3 days based on a review of subject status. Because of the critical nature of starting empiric broad-spectrum antibiotics, we will allow one dose of the antibiotic combination before consent and enrollment. This strategy is necessary for the ethical conduct of the study. Exclusion criteria: * Estimated creatinine clearance \< 30 mL/min * Liver impairment (liver enzymes \> 3 times upper limit) * Any history of allergy or contraindication to melatonin * Pregnancy or breastfeeding * Autoimmune disease * Requiring vasopressors * Requiring mechanical ventilation * History of acute kidney injury in the past 30 days * Inability to take oral medications * Clinical evidence of significant unstable or uncontrolled illness which, in the opinion of the research team, could confound the results of the study or put the patient at undue risk.
