Brief Summary
Hypoxic-Ischemic Encephalopathy (HIE) occurs in 20 per 1000 births. Only 47% of neonates treated with the state of the art therapy (induced systemic hypothermia) have normal outcomes. Therefore, other promising therapies that potentially work in synergy with hypothermia to improve neurologic outcomes need to be tested. One potential agent is melatonin. Melatonin is a naturally occurring substance produced mainly from the pineal gland. Melatonin is widely known for its role in regulating the circadian rhythm, but it has many other effects that may benefit infants with HI injury. Melatonin serves as a free radical scavenger, decreases inflammatory cytokines, and stimulates anti-oxidant enzymes. Therefore, melatonin may interrupt several key components in the pathophysiology of HIE, in turn minimizing cell death and improving outcomes. The research study will evaluate the neuroprotective properties and appropriate dose of Melatonin to give to infants undergoing therapeutic hypothermia for hypoxic ischemic encephalopathy.

Outcome Measures
Primary Outcomes (6)
To identify the maximum tolerated dose of Melatonin
The maximum tolerated dose (MTD) is defined as the highest dose level without adverse events in no more than 1 out of 6 patients
Changes in Baseline to day 3
Bayley-III Index Scores (Cognitive, Language, and Motor) will be used for neurological outcome assessment
All raw scores will be transformed into norm-referenced standard scores (scale mean = 100 with s.d. = 15) using the Bayley-III scoring software published with the test. To dichotomize "good" and "poor" outcomes for statistical analysis, standardized scores that are at or greater than one standard deviation below the normative sample mean published with the test (i.e., standard scores \< 85) will be classified as "poor outcome" while higher scores will be classified as "good outcome".
Approximately 18 - 20 Months
Peak Plasma Concentration (Cmax) of Melatonin 0.5 mg/kg.
HPLC-ESI/MS/MS will be used to measure melatonin concentrations in the serum samples. The two-way ANOVA (treatments are dose level and timepoint) framework for testing. Testing will be done using a likelihood ratio test, either using large-sample theory approximation or using bootstrap.
0 (baseline), 3, 5, 6, 12, 24, 48, 96 hours and day 14 (one sample)
Number of participants with treatment-related adverse events as assessed by MedDRA ??? This is something the PI/Team needs to agree on which one to use.
Incidence/Grade of Treatment Emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs), laboratory abnormalities Percentage and number of subjects who discontinued for adverse event
Baseline ongoing to Day 14
Peak Plasma Concentration (Cmax) of Melatonin 3 mg/kg.
HPLC-ESI/MS/MS will be used to measure melatonin concentrations in the serum. The two-way ANOVA (treatments are dose level and timepoint) framework for testing. Testing will be done using a likelihood ratio test, either using large-sample theory approximation or using bootstrap.
0 (baseline), 3, 5, 6, 12, 24, 48, 96 hours and day 14 (one sample)
Peak Plasma Concentration (Cmax) of Melatonin 5 mg/kg.
HPLC-ESI/MS/MS will be used to measure melatonin concentrations in the serum samples. The two-way ANOVA (treatments are dose level and timepoint) framework for testing. Testing will be done using a likelihood ratio test, either using large-sample theory approximation or using bootstrap.

Secondary Outcomes (2)
Bayley-III Index Scores Subscales (Receptive and Expressive Language, Fine and Gross Motor) will be used for neurological outcome assessment
Approximately 18 - 20 Months
Evaluation of The Impact of Melatonin using Magnetic Resonance Image (MRI)
Approximately 7 - 12 days
Study Arms (3)
Participants 1-10
EXPERIMENTALThis group will receive a 0.5 mg/kg enteral dose of Melatonin. The first dose will be administered via enteral route within 12 hours of life with a target of 6 hours of life. The melatonin will be administered as a single dose for the first 5 participants in allowing the investigators to determine if the dosing frequency has the potential to decrease in the elimination with hypothermia. The next 5 subjects who will receive multiple doses if there are not any safety concerns. Additionally, the participants will have the following test performed: Magnetic Resonance Imaging (MRI), Neurological Outcome Assessment, Pharmacokinetics, and safety monitoring.
Participants 11-20
EXPERIMENTALThis group will the Melatonin dose of 3 mg/kg enteral, only if the group Participants 1-10 has meet the safety goals. The first dose will be administered via enteral route within 12 hours of life with a target of 6 hours of life. The melatonin will be administered as a single dose for the first 5 participants in allowing the investigators to determine if the dosing frequency has the potential to decrease in the elimination with hypothermia. The next 5 subjects who will receive multiple doses if there are not any safety concerns. Additionally, the participants will have the following test performed: Magnetic Resonance Imaging (MRI), Neurological Outcome Assessment, Pharmacokinetics, and safety monitoring.
Participants 21-30
EXPERIMENTALThis group will receive Melatonin dose of 5 mg/kg enterally, only if the group Participants 11-20 has meet the safety goals. The first dose will be administered via enteral route within 12 hours of life with a target of 6 hours of life. The melatonin will be administered as a single dose for the first 5 participants in allowing the investigators to determine if the dosing frequency has the potential to decrease in the elimination with hypothermia.
