The Diaphragmatic Initiated Ventilatory Assist (DIVA) Trial
(DIVA)
What this study is about
DIVA is a pragmatic randomly assigned 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.
View original scientific description
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.
Interventions
DEVICE
NIV-NAVA
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.
DEVICE
NS-NIPPV
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.
Primary outcome measures
Extubation failure
Time frame: within the first 5 days (120 hours) post extubation
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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
