Study summary

The Brain Oxygenation-II study (BOx-II) is a phase-II, multicenter, single-arm clinical trial evaluating interventions based on near-infrared spectroscopy (NIRS) monitoring of cerebral oxygen saturation in extremely premature infants. Enrolled infants will follow a treatment guideline to maintain cerebral oxygen saturation in a target range within the first 72 hours of life. The primary outcomes will include interventions used to maintain cerebral saturation in target range, rates of cerebral hypoxia and systemic hypoxia, and a composite of death or severe brain injury detected on term-equivalent magnetic resonance imaging.

Inclusion criteria

  • Infants born with postmenstrual age less than 28 weeks
  • Signed

Exclusion criteria

Exclusion Criteria:

  • Missing written parental
  • Decision not to conduct full intensive care support
  • No possibility to place cerebral NIRS oximeter within six hours after birth
  • Skin integrity insufficient to allow for sensor placement as deemed by a clinician
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    Interventional Arm

    All infants will undergo non-invasive NIRS monitoring of cerebral oxygen saturation and will have algorithm-driven clinical interventions to maintain cerebral saturation within target range during the first 72 hours of life.

    Other: Intervention for cerebral hypoxia

Interventions

  • OtherIntervention for cerebral hypoxia

    For cerebral oxygen saturation measures below target range (cerebral hypoxia), a treatment algorithm with the following potential clinical interventions will be applied: fluid resuscitation, initiation of vasopressor/inotrope medication, change in mechanical ventilation or respiratory support, adjustment of fractional inspired oxygen, transfusion of red blood cells, acquisition of echocardiogram or cranial ultrasound.

What researchers measure

Primary outcomes

  1. Frequency of interventions used to address cerebral hypoxia

    Frequency of specific interventions chosen to address cerebral hypoxia

    Time frame: From birth until 72 hours of life

Secondary outcomes

  1. Rates of cerebral hypoxia and systemic hypoxia

    Rates of cerebral hypoxia as detected by near-infrared spectroscopy (NIRS) monitoring of cerebral oxygen saturation and systemic hypoxia as detected by conventional pulse oximetry monitoring of systemic oxygen saturation

    Time frame: From birth until 72 hours of life

  2. Rates of death or severe brain injury

    Rates of death or severe brain injury (including intraventricular hemorrhage, white matter injury, cystic periventricular leukomalacia, cerebellar hemorrhage, post-hemorrhagic ventricular dilation, or cerebral atrophy) detected on term-equivalent magnetic resonance imaging performed between 36 and 42 weeks corrected gestational age.

    Time frame: 36-42 weeks corrected gestational age

Other outcomes

  1. Rates of other neonatal morbidities

    Rates of other neonatal morbidities including bronchopulmonary dysplasia, severe retinopathy of prematurity, and/or mortality before neonatal intensive care unit discharge

    Time frame: Birth until hospital discharge, an average of 3 months
