Clinical trial Recruiting at 30 sites Phase 3 Interventional Ages 1 Hour to 24 Hours

APC-0101 with noninvasive breathing support for preterm infants with respiratory distress syndrome

Official title: A Randomized, Controlled, Blinded, Parallel Group Study of the Safety and Efficacy of APC-0101 (SF-RI 1 Surfactant for Inhalation Combined With a Dedicated Delivery System) in Preterm Infants With Respiratory Distress Syndrome

Run by Aerogen Pharma Limited · NCT06776783 · Data updated 2026-11-12

This will test whether inhaled APC-0101 given with nCPAP/NIV helps preterm infants with respiratory distress syndrome breathe better than nCPAP/NIV alone.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are inborn preterm infants born at 26–33 weeks gestation, 1–24 hours old, weighing ≤2000 g and appropriate for gestational age, who are on nCPAP/NIV with FiO2 ≥ 0.24 and imaging consistent with RDS.

Probably not a fit

Infants who are already intubated or have received prior surfactant, those on excluded respiratory supports (e.g., high-flow >2 LPM, SiPAP/RAM cannula), extremely preterm infants outside the gestational window, or those with key exclusion conditions are unlikely to benefit from this approach.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a two-part, prospective, randomized, blinded, sham-controlled, multicenter Phase 3 study comparing inhaled APC-0101 plus noninvasive respiratory support (nCPAP/NIV) to nCPAP/NIV with a sham delivery. APC-0101 consists of an inhaled surfactant formulation delivered via a dedicated device and is given to eligible preterm infants soon after birth; the control group receives standard nCPAP/NIV without active surfactant. In Part 1 infants are followed until 40 weeks post-menstrual age or NICU discharge, and in Part 2 selected infants undergo follow-up through 24 months corrected age to capture longer-term outcomes. Randomization occurs within 1–24 hours of life for inborn infants of 26–33 weeks gestation who meet respiratory support and imaging criteria.

Why it matters

Potential benefit: If successful, the intervention could reduce the need for intubation and instilled surfactant and improve short-term respiratory stability and longer-term lung outcomes for some preterm infants.

How similar studies have gone: Previous small studies of aerosolized or inhaled surfactant have shown mixed but promising results, so the approach is plausible but not yet proven in large trials.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:

1. Inborn at the study site's hospital (i.e., not transferred from another hospital following delivery)
2. Gestational age at birth of 26 through 33 weeks PMA
3. Birth weight appropriate for gestational age (AGA, weight 3rd to 97th percentile on Fenton Growth Curve)
4. Birth weight ≤ 2000 grams
5. Post-natal age 1 to 24 hours at randomization
6. On nCPAP or NIV for at least 30 minutes with RSS = 1.4 - 2.0 to maintain SpO2 90-95% at randomization. RSS is calculated as (nCPAP cm H2O) × (FiO2) or as (NIV mean airway pressure cm H2O) × (FiO2).
7. FiO2 ≥ 0.24 at randomization
8. nCPAP or mPaw ≥ 6 cm H2O at randomization
9. Chest radiograph (CXR) or lung ultrasound compatible with RDS prior to randomization

Exclusion Criteria:

1. On SiPAP®, RAM® cannula, or high flow nasal cannula (HFNC) (\> 2 liters per minute \[LPM\]) at the time of randomization
2. Prior instillation of surfactant
3. Premature rupture of membranes (PROM) occurring \> 14 days before birth
4. Significant congenital/chromosomal anomaly (e.g., Pierre Robin syndrome, clinically significant congenital heart disease, or trisomy)
5. Pneumothorax
6. Other etiologies of respiratory distress
7. Enrollment in another interventional study with similar efficacy endpoints
8. Apgar score at 5 min of 0-3
9. Prior cardiopulmonary resuscitation (CPR) or epinephrine
10. Base Deficit \> 15 mEq/L on most recent arterial blood gas (not capillary blood gas, venous blood gas, or cord gas) prior to randomization. Note that arterial blood gas is not required prior to randomization.
11. Partial pressure of carbon dioxide (PaCO2) \> 65 mmHg on most recent arterial blood gas (not capillary blood gas, venous blood gas, or cord gas) prior to randomization.
12. Triplet or higher order multiple birth
