NCT05459298

Brief Summary

The objective of the study is to compare supplementation with vitamin D at 800 IU/day to usual care for the first 28 days after birth with respect to 25 (OH) vitamin D levels and indicators of likely or plausible effects of vitamin D supplementation on the function or structure of the lung, bones, immune system, and brain in extremely premature (EP) infants who are \<28 weeks gestational age (GA) or \<1000 grams of birth weight (BW). The study results will be analyzed as intention to treat Bayesian analyses (Frequentist analyses will also be performed).

  • Number of participants who are still on respiratory support

    22 to 26 months corrected age

  • Number of days of supplemental oxygen

    from time of birth to time of discharge (about 0 to 60 weeks after birth)

  • +31 more secondary outcomes

Study Arms (2)

Usual care plus placebo

ACTIVE COMPARATOR

Infants will receive placebo (normal saline) in the first 28 days after birth. Care will be unaffected and provided based on the judgment of the attending neonatal faculty and NICU policies and routine practices. When the infant receives about 120 to 160 mL/kg/day of fortified milk at 24 kcal/ounce, the infant will receive supplementation with 400 IU/day of vitamin D as usual care.

Dietary Supplement: PlaceboOther: Usual Care

Usual care plus vitamin D supplementation

EXPERIMENTAL

Infants will receive cholecalciferol 800 IU/day in the first 28 days after birth, given enterally four times per day (0.5mL per dose = 200 IU) until the infant is provided 400 IU/day (when feedings reach about 120 -160 mL/kg/day). At that point the study cholecalciferol will be reduced to 400 IU/day for a total supplementation of 800 IU/day.

Interventions

PlaceboDIETARY_SUPPLEMENT

Placebo is normal saline, given in the first 28 days after birth, prepared to have the same volume and appearance as vitamin D, which is a clear odorless solution.

Also known as: Normal saline
Usual care plus placebo

800 IU/day Vitamin D supplementation until 400 IU/day are provided as part of usual care (started when infants receive full feedings of about 120-160 mL/kg/day). At that point the intervention becomes a supplement of 400 IU/day above that given with usual care. In this way all infants in the intervention group receive 800 IU/day of vitamin D total supplementation in the first 28 days after birth with feedings.

Also known as: Cholecalciferol
Usual care plus vitamin D supplementation

Care will be unaffected and provided based on the judgment of the attending neonatal faculty and NICU policies and routine practices. When the infant receives about 120 to 160 mL/kg/day of fortified milk at 24 kcal/ounce, the infant will receive supplementation with 400 IU/day of vitamin D as usual care.

You may qualify if:

  • Infants born at \< 28 weeks gestational age (GA) or \<1000 grams birth weight (BW)
