About this study

Official title: Randomized Clinical Trial of Dexamethasone Therapy in Very-Low-Birth-Weight Infants at Risk for Chronic Lung Disease (CLD)

Infants who are on breathing support are often treated with steroids (dexamethasone); however, the best timing of therapy is not known. This trial looked at the benefits and hazards of starting dexamethasone therapy at two weeks of age and four weeks of age in premature infants.

Read the detailed description

Ventilator-dependent premature infants are often treated with dexamethasone. However, the optimal timing of therapy is unknown. We compared the benefits and hazards of initiating dexamethasone therapy at two weeks of age and at four weeks of age in 371 ventilator-dependent very-low-birth-weight infants (501 to 1500 grams) who had respiratory-index scores (mean airway pressure x the fraction of inspired oxygen) of greater than or equal 2.4 at two weeks of age. The primary outcome was the number of days from randomization to extubation not requiring reintubation (extubation score or death). The secondary outcomes were death before discharge from the hospital; the duration of assisted ventilation, supplementary oxygen therapy and hospital stay; the incidence of chronic lung disease (defined as the need for supplemental oxygen at 36 weeks postconceptional age by best obstetrical estimate) and rates of morbidity and mortality from respiratory causes during the first year. Additional secondary endpoints were hyperglycemia, hypertension, growth, bacteremia, necrotizing enterocolitis and upper GI bleeding.

The sample size of 370 was based on a 0.60 probability that the extubation score of late treatment was greater than early treatment, a 5% two-sided type 1 error, 85% power, and 10% treatment noncompliance.

Infants were randomized to either receive dexamethasone for two weeks followed by saline placebo for two weeks, or saline placebo for two weeks followed by either dexamethasone or additional placebo for two weeks (if they still met entry criteria). Dexamethasone was given at a dose of 0.25 mg per kilogram of body weight twice daily intravenously or orally for five days, and the dose then tapered.

The median time to ventilator independence was 36 days in the dexamethasone-placebo group and 37 days in the placebo-dexamethasone group. The incidences of chronic lung disease (defined as the need for oxygen supplementation at 36 weeks postconceptional age) were 66 percent and 67 percent, respectively. Dexamethasone was associated with an increased incidence of nosocomial bacteremia (relative risk, 1.5; 95 percent confidence interval, 1.1 to 2.1) and hyperglycemia (relative risk, 1.9; 95 percent confidence interval, 1.2 to 3.0) in the dexamethasone-placebo group, elevated blood pressure (relative risk, 2.9; 95 percent confidence interval, 1.2 to 6.9) in the placebo-dexamethasone group, and diminished weight gain and head growth (P less than 0.001) in both groups. Treatment of ventilator-dependent premature infants with dexamethasone at two weeks of age is more hazardous and no more beneficial than treatment at four weeks of age.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Dexamethasone EarlyDrug

    Tapering course of dexamethasone in doses given twice a day (0.25 mg per kilogram of body weight per dose for five days, then 0.15 mg, 0.07 mg, and 0.03 mg per kilogram per dose for three days each), followed by two weeks of saline.

  • Dexamethasone LateDrug

    Saline for two weeks, followed by either the same tapering two-week course of dexamethasone given to the first group, if the respiratory-index score was >=2.4 on treatment day 14, or an additional two weeks of saline

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Dexamethasone Early and Dexamethasone Late in people with Infant, Newborn and Infant, Low Birth Weight, run by NICHD Neonatal Research Network at 13 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of days from randomization to ventilator independence, defined as extubation not requiring reintubation, or extubation followed by elective reintubation for seven days or less so that the infant could undergo a surgical procedure (time frame: At hospital discharge). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00011362, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Mar 2019.
