Is this trial a fit for you?

Likely a good fit

Ideal candidates are extremely premature infants born before 29 weeks who either have BPD at the 36-week assessment (Phase 0) or are 7–30 days old and still require respiratory support (Phase 1).

Probably not a fit

Infants with persistent hypoglycemia, lactic acidosis, feeding intolerance, significant renal or hepatic dysfunction, active infection, congenital anomalies preventing feeds, or those on palliative care are excluded and unlikely to benefit.

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

What this trial studies

This is an open-label, early-phase pilot trial using dose-escalation cohorts to study safety and tolerance of oral metformin in very preterm infants at risk for or diagnosed with BPD. Phase 0 enrolls older premature infants (born <29 weeks, postnatal age 8–22 weeks with BPD at 36 weeks) and gives metformin twice daily across four dose groups (5–25 mg/kg/day) for 3, 7, or 14 days. Phase 1 enrolls extremely premature infants (born <29 weeks, 7–30 days old who require mechanical ventilation or positive pressure at day 7) and gives once-daily metformin across four dose groups (15–25 mg/kg/day) for 3, 7, or 14 days. The primary focus is safety and tolerability, with clinical monitoring for adverse events and feeding/ metabolic effects at a single site.

Why it matters

Potential benefit: If successful, metformin could reduce lung injury and promote lung growth, potentially lowering BPD severity and the need for prolonged respiratory support.

How similar studies have gone: Using metformin to treat lung disease in premature infants is largely novel in humans, with limited clinical data but some supportive animal and preclinical studies.
