About this trial

DIVA is a pragmatic randomized clinical trial (RCT) to determine: among (P) preterm infants born 23 0/7-28 6/7 weeks gestation undergoing extubation from mechanical ventilation, whether (I) Non-invasive neurally adjusted ventilatory assist (NIV-NAVA) (C) compared with Non-synchronized nasal intermittent positive pressure ventilation (NS-NIPPV), will reduce the incidence of (O) extubation failure within (T) 5 days (120 hours) of extubation.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Gestational age of 23 0/7- 28 6/7 weeks at birth

Intubated in the first 7 days of life

Undergoing extubation following at least 12 hours of invasive mechanical ventilation

Post-natal age <32 weeks Post menstrual age at time of extubation

Disqualifiers

Major congenital anomalies, including pulmonary hypoplasia

Neurologic disorders affecting respiratory drive (other than apnea of prematurity)

Esophageal bleeding or other contraindication to NG/OG catheter placement

Current weight <500 grams (based on Edi catheter approval)

Trial design

Design model

Parallel

Treatments tested in this trial

  • NIV-NAVA

    Device

    Infants in the intervention arm will be managed with non-invasive neurally adjusted ventilatory assist (NIV-NAVA) using FDA-approved servos with associated FDA-approved Edi catheter.

  • NS-NIPPV

    Device

    Infants in the active comparator arm will be treated with non-synchronized non-invasive positive pressure ventilation (NIPPV) through FDA-approved ventilators currently in use at each site.

Treatment groups

478 Participants
are divided into 2 treatment groups
Group A: NIV-NAVAExperimental treatment 1 intervention
Group B: NS- NIPPVActive comparator 1 intervention

Trial outcomes

Primary outcomes

1

Extubation failure

Extubation failure is defined when an infant is on the allocated mode of respiratory support and meets any of the following 4 criteria: (1) Rise in FiO2 at least 20% from pre-extubation value for \>2 hours to maintain local SpO2 targets, (2) pH ≤7.20 or pCO2 ≥70mm Hg; (3) \>1 apneic event requiring positive pressure ventilation (PPV) within 6 hours or ≥ 6 apneic events requiring stimulation within 6 hours (4) emergent intubation by the clinical team for cardiovascular instability or surgery.

Time frame
within the first 5 days (120 hours) post extubation

Secondary outcomes

1

Bronchopulmonary Dysplasia (BPD) at 36 weeks PMA

BPD will be assessed as an ordinal outcome (none, grade 1, 2, 3), according to the NRN criteria.

Time frame
36 weeks PMA
2

Death or BPD at 36 weeks PMA

Composite dichotomous (y/n) outcome of death or grade 2/3 BPD, using the NRN criteria

Time frame
36 weeks PMA
3

Endotracheal intubation through 36 weeks PMA

Endotracheal intubation will be assessed 2 ways: As a dichotomous (y/n) outcome if it occurs at any time and also as days until endotracheal intubation (with censoring at 36 weeks PMA)

Time frame
36 weeks PMA
4

Postmenstrual age at last invasive ventilation

Time to cessation of invasive ventilation, with censoring at 36 weeks PMA

Time frame
36 weeks PMA

Other outcomes

1

Death

Death will be measured in two ways (1) as a dichotomous (y/n) outcome if death occurs prior to 36 weeks PMA, and (2) days until death (with censoring at 36 weeks PMA).

Time frame
From randomization through 36 weeks PMA
2

Air Leaks

Air leaks will be measured as a dichotomous (y/n) outcome if a new pulmonary interstitial emphysema or pneumothorax occurs at any time after randomization until 36 weeks PMA.

Time frame
From randomization through 36 weeks PMA
3

Gastrointestinal perforation or bleeding

This will be measured as a dichotomous (y/n) outcome if a new GI perforation or bleeding occurs at any time after randomization until 36 weeks PMA.

Time frame
From randomization through 36 weeks PMA
4

Regional distribution of lung aeration

this will be measured with electrical impedance tomography in a subset of patients

Time frame
From extubation through 5 days after extubation
