Melatonin for Prevention of Kidney Injury
Study Details
Study Description
Brief Summary
This study will evaluate the safety and effectiveness of melatonin for the prevention of antibiotic associated acute kidney injury in hospitalized patients.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
|
Phase 3 |
Detailed Description
Consenting subjects meeting inclusion and exclusion will be randomized to receive melatonin 5 mg daily or a matching placebo. Study subjects will be followed for the duration of hospitalization or discontinuation of broad spectrum antibiotics (vancomycin plus piperacillin/tazobactam). The primary outcome and secondary outcomes will be evaluated by the study team.

Outcome Measures
Primary Outcome Measures
- Acute kidney injury [From date of randomization until the date of first documented acute kidney injury or date of antibiotic discontinuation, whichever came first, assessed up to 28 days]
Acute kidney injury will be defined as an increase in sCr from baseline of >/= 0.3 mg/dL or a >/= 50% increase from baseline.
Other Outcome Measures
- Melatonin plasma trough concentration [Days 3, 5, and 7]
Evaluate the steady state plasma trough concentration of melatonin
- Piperacillin/tazobactam plasma trough concentration [Days 3, 5, and 7]
Evaluate the steady state plasma trough concentration of piperacillin/tazobactam
- Vancomycin plasma Area Under the Curve (AUC) [Days 3, 5, and 7]
Evaluate the steady state plasma AUC of vancomycin
- Association between Kidney Injury Molecule-1 (KIM-1) and serum creatinine [Days 3, 5, and 7]
Measure KIM-1 in plasma and urine and evaluate discordance between serum creatinine.
- Mitochondrial stress assessment via extracellular flux analysis to measure oxygen consumption rate of cells [Days 1 and 3]
Evaluate mitochondrial stress in peripheral blood mononuclear cells from a subset of subjects in each group. In addition, mitochondrial stress will be evaluated on day 3 in a subset in the melatonin group.
- Urine mitochondrial DNA copy number [Days 1, 3, 5, and 7]
Measure mitochondrial DNA (mtDNA) in urine samples using polymerase chain reaction (PCR).
- Fold-change in NRF-2 gene expression in peripheral blood mononuclear cells [Days 1 and 5]
Measure gene expression level at baseline and then on day 5 (or last day of study if earlier) using polymerase chain reaction (PCR) and compare the fold-change from baseline between groups.
- Number of subjects with NRF2 DNA single nucleotide polymorphisms [Day 1]
Determination of the number of individuals with NRF2 DNA single nucleotide polymorphisms in the study population and compare the incidence of primary outcome in those with and without polymorphisms.
- Number of subjects with KEAP1 DNA single nucleotide polymorphisms [Day 1]
Determination of the number of individuals with KEAP1 DNA single nucleotide polymorphisms in the study population and compare the incidence of primary outcome in those with and without polymorphisms.
Eligibility Criteria
Criteria
Inclusion criteria:
-
Aged 18 to 65 years
-
Currently prescribed vancomycin and piperacillin/tazobactam 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.
