PREMILOC Trial to Prevent Bronchopulmonary Dysplasia in Very Preterm Neonates (PREMILOC)

September 28, 2018 updated by: Assistance Publique - Hôpitaux de Paris

Early Prevention of Broncho-pulmonary Dysplasia and Neonatal Mortality in Very Preterm Infants Using Low Dose of Hydrocortisone: a Randomized Controlled Trial

There is increasing evidence linking a fetal and early neonatal systemic inflammatory response syndrome to the subsequent development of bronchopulmonary dysplasia (BPD) and white matter injury (WMI) in very preterm infants. Babies with evidence of adrenal insufficiency early in life may not be able to control the inflammatory response and are thereby more likely to develop BPD than babies who do not show such evidence of inflammation. We designed a randomized controlled trial to test the hypothesis whether very preterm babies at high-risk of BPD, treated with low doses of HC during the first 10 days of life, are more likely to survive without BPD at 36 weeks of post-menstrual age (PMA), compared to babies treated with placebo.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Individual patients and study procedures. Entry criteria: gestational age between 24 weeks and 27 weeks + 6 days, babies born to mother with either clinical chorioamnionitis, preterm and prelabor rupture of the membranes (PPROM), or preterm labor, written informed consent obtained before inclusion and randomization. Exclusion criteria: babies born with birth weight below the 3th percentile, PPROM before 22 weeks, major fetal anomaly or congenital malformation, mother refusal or inability to provide consent. Stratification: stratum A: 24-25 weeks and stratum B: 26-27 weeks. Centrally controlled randomization takes place between 12 and 48 hours of age and patients assigned to the HC group are treated with 0,5 mg/kg HC intravenously twice a day for seven days and once a day for the next three days. Ibuprofen is only given to babies with persistent ductus arteriosis (PDA) echocardiographically confirmed at 24 hours of age or older.

Outcome variables. The primary outcome is a dichotomous variable: survival without BPD at 36 weeks PMA. A consistent physiologic definition of BPD will be used by all participating centres (Walsh MC, Pediatrics 2004;114:1305-11). Secondary outcome variables include features of WMI on MRI performed at 40 weeks PMA and neurodevelopmental outcome at 2-year of corrected age. Other outcome variables include death before discharge, BPD at 28 days and 36 weeks, duration of mechanical ventilation and O2 supplementation, need for vasopressors, use of open-labeled postnatal steroids (HC or dexamethasone), confirmed or suspected early and late onset sepsis, PDA, gastrointestinal perforation, NEC, ROP, IVH, biological markers of the neonatal inflammatory response syndrome.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

No older than 1 day (Child)

Accepts Healthy Volunteers

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
