Single-dose Prophylactic INdomethacin in Extremely Preterm Infants - A Multicenter Randomized Blinded Placebo-Controlled Trial (the SPIN RCT)
University of British Columbia
Summary
In Canada, about 900 babies each year are born very early (\<26 weeks of gestation) and have a high chance of dying or having a serious bleed in the brain. Families of these extremely preterm babies consider preventing severe brain bleeding as critical to their child's health and well-being. A medicine called indomethacin, when given intravenously in 3-doses, is known to reduce severe brain bleeding. But use of this drug is variable among clinicians working in the neonatal intensive care unit (NICU) due to (a) its side effects on the gut; (b) possible harm when used with other medications; (c) a notion that despite reducing brain bleeds, the child's long-term brain development is not improved. Emerging evidence suggests that a single low-dose indomethacin regimen may be equally effective in reducing severe brain bleeding as compared to a traditional 3-dose regimen. The investigators propose a blinded randomized controlled trial, a study design where babies born \<26 weeks will be randomly assigned within 12 hours of birth to either a single dose of intravenous indomethacin or similar looking placebo in the form a saline solution. The study will test if a single dose indomethacin regimen is effective in improving survival of these babies without the devastating complication of severe brain bleeding. In this study the care providers and researchers will be unaware as to which baby receives indomethacin and which baby receives placebo to ensure no one's expectations or biases can influence the results. The investigators will conduct the study in multiple NICUs across Canada, the United States and Australia in 2 phases: First, an internal pilot phase that will enroll 104 babies born \<26 weeks or \<750 g birth weight over a period of 1 year. If the investigators are successful in achieving their target enrolment in the pilot phase, they will move on to the second phase and continue enrollment up to a total of 500 babies born \<26 weeks or \<750 g birth weight over a period of 3 years. The total of 500 babies will include the 104 babies enrolled in the first phase of the study. This study will help the investigators determine in the most unbiased way whether a single dose of indomethacin given immediately after birth in the smallest babies born \<26 weeks of gestation can safely and effectively reduce severe brain bleeding.
Description
BACKGROUND \& IMPORTANCE In Canada, about 900 infants are born extremely preterm at \<26 weeks of gestation (GA); nearly four out of 10 of them do not survive or develop severe intraventricular hemorrhage (sIVH). Existing evidence shows that a 3-dose regimen of prophylactic intravenous indomethacin (0.1mg/kg/dose every 24h for 3 doses most commonly used clinically) results in a significant reduction in sIVH, an outcome deemed critical by families. However, use of the conventional 3-dose regimen has declined among clinicians due to perceived adverse effects on the gut, presumed lack of long-ter…
