Brief Summary
This study is being done to see if additional caffeine citrate (20 milligrams per kilogram IV bolus) helps babies with low kidney oxygenation already being treated with caffeine citrate (20 milligrams per kilogram IV bolus on day of life (DOL) 1 followed by 8 milligrams per kilogram daily maintenance). The investigators hypothesize that additional caffeine will improve kidney oxygen levels, while not causing any brain injury, and may reduce rates of acute kidney injury compared to placebo. This study will take place in preterm babies born less than 30 weeks gestational age, with the intervention occurring between greater than 48 hours of age until DOL 14 and outcomes tracked until neonatal intensive care unit (NICU) discharge.

Outcome Measures
Primary Outcomes (1)
Proportion of Participants with Improvement in Kidney Oxygenation
In the 3 hours after receiving the intervention or placebo, participants have kidney oxygenation monitored. Improvement in oxygenation is defined as having 30 minutes where at least 90 percent of measured values are at least 50 percent.
Up to 3 hours post-intervention (Between days 1 and 17)
Secondary Outcomes (2)
Number of Days of Acute Kidney Injury (AKI)
14 days after intervention
Proportion of Participants with a Sustained Decrease in Cerebral Oxygenation
up to 3 hours post-intervention (Between days 1 and 17)
Other Outcomes (3)
Change in Urinary Biomarker Concentrations
baseline, day 17
Rates of Brain Injury
up to 6 months
Rates of Abnormal General Movement Assessment (GMA)
up to 6 months

Eligibility Criteria
You may qualify if:
- Gestational age at birth between 23 0/7 and 29 6/7 weeks.
- Able to have near-infrared spectroscopy (NIRS) monitoring of cerebral and kidney oxygenation.
- Able to receive IV medications.

You may not qualify if:
- Known or suspected major congenital anomaly of the brain, heart, lungs or kidney (excluding UTD A1 pyelectasis).
- Known or suspected chromosomal or genetic anomaly.
- Not suitable for study participation due to other reasons at the discretion of the investigators.

This study will submit data to the National Institute of Child Health and Human Development (NICHD) Data and Specimen Hub (DASH). NICHD DASH is a NICHD-funded controlled access data repository established to facilitate data sharing and access to biospecimens for all NICHD clinical research. This study will produce four data types: Clinical data, Urine proteomic biomarker, PK/PD data, and near infrared spectroscopy (NIRS) oxygenation data. The final clinical dataset will include demographic data and study-related tests obtained from the electronic medical record. The urine proteomic data will contain output from the biological urine samples from each research subject. The PK/PD data will contain caffeine serum concentration and renal oxygenation data at various timepoints, dose levels, and selected demographic and clinical data. The NIRS oxygenation dataset will include every 1 second kidney and cerebral oxygenation percentage generated/obtained from INVOS Medtronic NIRS 7100 devices.
