Inhaled Beclomethasone to Prevent Chronic Lung Disease
Study Details
Study Description
Brief Summary
To test if inhaled glucocorticoids, early in the course of respiratory failure in premature infants, permit normal lung growth and differentiation, thus preventing development of bronchopulmonary dysplasia.

Detailed Description
BACKGROUND:
Bronchopulmonary dysplasia (BPD), a fibrotic/emphysematous lung disorder is a common sequela among extremely premature infants. The severity of BPD, but not incidence, has been reduced by surfactant therapy. BPD remains one of the most significant contributors to excessively prolonged hospital stays and, therefore, potentially avoidable costs. Research leading to a reduction in BPD morbidity should prove cost effective in the estimated 10,400 affected infants annually (40 percent of a projected 26,000 survivors of birthweights less than 1,250 grams).
Inflammation is a significant component of both clinical and experimental model BPD and is the subject of numerous basic science investigations begun since the empiric observation that BPD responds favorably to systemic steroids. The known side effects of systemic steroids have led to their cautious sequential controlled clinical investigation, initially for late treatment (at more than 30 days of age), then early treatment (two weeks), then very early treatment (seven days), and even prophylaxis (day one). The prophylactic clinical trial of inhaled steroids, starting at day three for 21 days, is a logical next step in this sequence of determining the least dangerous, yet effective means to prevent or treat the inflammatory components of BPD.
DESIGN NARRATIVE:
Multicenter, randomized, double-blind, placebo-controlled. The premature infants were randomized to beclomethasone or placebo on day three of life. Beclomethasone was delivered in a decreasing dosage, from 40 to 5 micrograms per kilogram of body weight per day, for four days. The primary outcome measure was bronchopulmonary dysplasia at 28 days of age. Secondary outcomes included bronchopulmonary dysplasia at 36 weeks of postmenstrual age, the need for systemic glucocorticoid therapy, the need for bronchodilator therapy, the duration of respiratory support, and death.
Clinical sites included the Boston Perinatal Center at the New England Medical Center Hospitals, the Baystate Medical Center in Springfield, Massachusetts, and the Pennsylvania Hospital in Philadelphia. The Data Coordinating Center was at Boston University School of Medicine. Support for the trial ended in April, 1999.
The study completion date listed in this record was obtained from the "End Date" entered in the Protocol Registration and Results System (PRS) record.
