Intervention for Brain Hypoxia in Premature Infants
(BOx-II Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new method to assist extremely premature infants at risk of cerebral hypoxia. The treatment uses a special monitor to track brain oxygen levels, guiding doctors to maintain healthy levels during the first three days of life. The goal is to reduce the risk of brain injury or serious health issues. The trial seeks infants born before 28 weeks of pregnancy. As a Phase 2 trial, it measures the treatment's effectiveness in an initial, smaller group of infants, providing an opportunity to contribute to important research.
Do I need to stop my current medications for the trial?
The trial information does not specify whether participants need to stop taking their current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this intervention is safe for premature infants?
Research has shown that cerebral oximetry, a method to check brain oxygen levels, has been studied in very premature babies. One study found that monitoring and adjusting treatment based on these oxygen levels did not reduce the risk of death or severe brain injury. However, the SafeBoosC-II trial found that this method helped maintain more stable brain oxygen levels.
While some studies have reported death rates in babies using this monitoring, these findings are part of broader research exploring the benefits and risks. Overall, cerebral oximetry appears to be a well-accepted method for managing brain oxygen levels in premature infants, aiming to create a more stable environment for their developing brains.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it explores a non-invasive approach to managing cerebral hypoxia in premature infants, using NIRS monitoring to track brain oxygen levels. Unlike traditional methods that may involve invasive procedures or delayed responses to hypoxia, this technique uses real-time data to guide interventions, aiming for immediate stabilization of oxygen levels. This approach could potentially offer a safer, more responsive way to protect the delicate brains of preterm infants during their critical early days.
What evidence suggests that this intervention is effective for brain hypoxia in premature infants?
Research has shown that using near-infrared spectroscopy (NIRS) to monitor brain oxygen levels in very premature babies can help maintain stability. In this trial, infants in the interventional arm will undergo non-invasive NIRS monitoring of cerebral oxygen saturation, with algorithm-driven clinical interventions to keep levels within the target range during the first 72 hours of life. The SafeBoosC-II study found that this method stabilized brain oxygen levels, ensuring a consistent oxygen supply to the brain, which is crucial in the early days. Although the SafeBoosC-III trial did not find significant differences in outcomes like death or severe brain injury compared to regular care, maintaining stable oxygen levels is still considered beneficial for the overall health of these infants.13678

Are You a Good Fit for This Trial?
The Brain Oxygenation-II study is for extremely premature infants born before 28 weeks of pregnancy. To participate, parents must give written consent and the infant must be able to have a cerebral NIRS oximeter placed within six hours after birth. Infants not receiving full intensive care or with skin issues preventing sensor placement cannot join.Inclusion Criteria
