Optimizing PreTerm Infant Ampicillin Dosing (OPTI-Amp)
An Open-label, Pharmacokinetic and Safety Trial Optimizing PreTerm Infant Ampicillin Dosing
The goal of this clinical trial is to learn if preterm infants who are prescribed antibiotics shortly after birth can safety receive a shorter course of antibiotics (24 to 36 hours instead of 48 hours). The main questions it aims to answer are:
- Does short-course ampicillin provide high enough levels of ampicillin at 48 hours?
- Is short-course ampicillin safe for preterm infants to receive?
Preterm infants who are being prescribed ampicillin by their doctor and enroll in the study will stop ampicillin after a shorter than typical course, and researchers will collect blood samples to measure their ampicillin levels and follow them clinically to see how they do after receiving short-course ampicillin.
Participants will:
- stop ampicillin earlier than 48 hours (between 24 to 36 hours, depending on how premature they are and the dosing of ampicillin their doctor has prescribed)
- have one or more blood samples collected, including one around 48 hours from when they started ampicillin
- have their data collected until 30 days after they receive short-course ampicillin, or until hospital discharge, whichever is sooner

Descripción detallada
OPTI-Amp is a prospective, open-label, non-randomized pharmacokinetic and safety trial of short-course ampicillin administered to preterm neonates in the Neonatal Intensive Care Unit (NICU) at Duke.
The objectives of the study are to 1) evaluate whether short-course ampicillin provides therapeutic exposures for 48 hours from ampicillin initiation for preterm neonates undergoing evaluation of early onset sepsis (EOS) and 2) evaluate the safety of short-course ampicillin compared to standard empiric ampicillin. The prescribing of drugs to infants will not be part of this protocol.
Approximately 60 neonates ≤34 weeks gestational age and <7 days postnatal age at the time of screening, who are receiving empiric ampicillin prescribed per standard of care (SOC) by their treating provider will be enrolled in the study. Participants will be in the study up to 30 days or hospital discharge, whichever is sooner. Enrolled infants who receive short-course ampicillin will have a pharmacokinetic sample collected at 48 (+/-2) hours from the time that ampicillin was initiated. Additional opportunistic pharmacokinetic (PK) samples can be collected between enrollment and 72 hours from ampicillin initiation if the patient is receiving other SOC labs; however, these are not required. Demographic information, clinical data, and biospecimen information (including date and time of sample collection) will also be collected for enrolled participants.
All enrolled infants will be in the safety population. Those with at least one PK sample will be included in the PK population. In addition to the risks of blood drawing and loss of confidentiality, there may be a risk of under treatment of EOS if clinical cultures result positive after ampicillin discontinuation and therapeutic exposure is not maintained between 24 or 36 hours until 48 hours. Participants that fall under the latter situation will either not be enrolled in the study or will be withdrawn as determined by the study PI.

Experimental: Short-course Ampicillin
Infants enrolled in the trial receive short-course empiric ampicillin (24 to 36 hours, depending on gestational age and prescribed dosing regimen), rather than a standard (48 hour) empiric ampicillin course
|
preterm infants receive less than 48 hours of prescribed ampicillin (i.e., a "short-course" ampicillin regimen) to provide the desired 48 hours of therapeutic exposures
