Comparison of Efficacy of Less Invasive Surfactant Treatment Under Nasal CPAP and Nasal IPPV in Premature Babies: CURLISPAP Study

Non invasive ventilation is important in the care of preterm infants with respiratory failure, and surfactant treatment can be use with non invasive ventilation. However, there is no consensus on the best non-invasive ventilation mode for surfactant treatment in preterm infants.

Objective: To compare the effectiveness of nasal intermittent positive pressure ventilation (NIPPV) versus nasal continuous positive airway pressure (CPAP) in preterm infants ≤ 29 week gestational age.

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

This CURLISPAP study was a multicenter, randomized controlled study at six level III neonatal intensive care units (NICUs) in Turkey. The protocol was approved by the ethics committee of each participating centre and Turkish Ministry of Health, Turkish Medicines and Medical Devices Agency.

Non invasive ventilated preterm infants with respiratory distress syndrome and gestational age from 241/7 weeks to 296/7 weeks were enrolled within 6 h of birth. Infants with major congenital malformations, need of mechanical ventiation, need of entubation in delivery room and lack of parental consent were excluded. Enrolled infants will randomize into two study groups (NIPPV group and CPAP group). The short binasal prongs will use as interface. For all the groups, if the fraction of inspired oxygen (FiO2) requirement is persistently higher than 0.30 target SpO2 90-94%.

For all groups Surfactant by "LISA" technique and with special catheter (LISAcath, Chiesi Pharmaceutics) of surfactant (Curosurf, Chiesi Pharmaceutics) 200 mg/kg.

The primary end-point, need of mechanical ventilation within 72 hours following surfactant treatment, will compared between the groups. Short and long-term neonatal outcomes will also evaluate.

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Active Comparator: NCPAP

Ventilator-derived NCPAP will be administered using binasal prongs. Standard Devices or infant flow-driver device. Initial NCPAP settings are: PEEP:6 cmH2O and FiO2: adjusted to keep preductal sPO2 between %90-94.

Failure is defined as FiO2 requirement of >%50, capillary blood gas obtained at the 4th hour of therapy showing pH<7.20 or pCO2>60 cmH2O.
Other: NCPAP
NCPAP infants will be randomized into two different non invasive ventilation groups
Other: NIPPV
NIPPV NCPAP infants will be randomized into two different non invasive ventilation groups
Active Comparator: NIPPV

Ventilator-derived NIPPV will be administered using binasal prongs. Standard Devices or infant flow-driver device. Initial NIPPV settings are: PEEP:6 cmH2O, PIP: 15 cmH2O, Rate: 30-40/ bpm and FiO2: adjusted to keep preductal sPO2 between %90-94.

Failure is defined as FiO2 requirement of >%50, capillary blood gas obtained at the 4th hour of therapy showing pH<7.20 or pCO2>60 cmH2O.
Other: NCPAP
NCPAP infants will be randomized into two different non invasive ventilation groups

What is the study measuring?

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.
Outcome Measure
Measure Description
Time Frame
Treatment failure within 72 hours after randomization 72 hours after randomization
Time Frame: within 72 hours after randomization
Need for invasive mechanical ventilation
within 72 hours after randomization

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Rate of bronchopulmonary dysplasia
Time Frame: 36 weeks of postmenstrual age ]
defined according to the NICHD definition
