About this study

The investigators propose the present study with the following aims:

  • to determine whether early patent ductus arteriosus (PDA) treatment with ibuprofen treatment at the onset of clinical symptoms is superior to late ibuprofen treatment only when symptoms of a hemodynamically significant PDA are present in the evolution of bronchopulmonary dysplasia (BPD) defined as duration of supplemental oxygen exposure during the first 28 days
  • to determine whether early PDA treatment with ibuprofen will be superior to late treatment with ibuprofen in efficacy of PDA closure, need for rescue therapy, need for PDA ligation and incidence of major complications of prematurity.

Hypothesis: Early pharmacologic closure of PDA with ibuprofen will improve respiratory course and reduce BPD as reflected by a reduction in duration of supplemental oxygen during the first 28 days of age vs. late pharmacologic treatment with ibuprofen.

Outcome variables: The primary outcome of this study is the number of days spent on supplemental oxygen by each infant during the first 28 days.

Other outcomes to be determined between groups include:

  • Mortality
  • Other respiratory variables: total days on supplemental oxygen, days on mechanical ventilation, oxygen dependence at 36 weeks post menstrual age, age at final extubation.
  • Other respiratory complications: pneumothorax, pulmonary interstitial emphysema, need for high frequency ventilation, pulmonary hypertension
  • Efficacy of PDA closure: number of courses of medication required, need for ligation
  • Other neonatal complications: intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL), retinopathy of prematurity (ROP), necrotizing enterocolitis (NEC), intestinal perforation, sepsis, renal dysfunction (oliguria, elevated creatinine)
  • Time to achieving full enteral feedings, time to regain birth weight, weight at discharge.
  • Length of hospital stay

What participants receive

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

  • Early ibuprofenDrug

    IBUPROFEN SCHEDULE: initial dose 10 mg/kg, then 2 doses 5 mg/kg each, after 24 and 48 h, slow IV infusion. Initial therapy is blinded. At PDA diagnosis, infants randomized to "early treatment" receive blinded ibuprofen. Infants randomized to "late treatment" receive blinded placebo. Hemodynamically significant PDA criteria: SIGNS OF PDA + pulmonary hemorrhage OR SIGNS OF PDA +: Pulmonary edema, plus a large heart on CXR + one of the following: Hypotension, Respiratory failure (due to PDA) defined as at least two of the following: Need for supplemental O2 > 50%; need IMV >40; need for PIP > 20; or need for HFOV. Once hemodynamically significant PDA criteria met, if echo is positive, infants from both groups can receive open label ibuprofen.

  • Late ibuprofen expectant group (placebo)Other

    Drug: Late ibuprofen expectant group (placebo): DOSING SCHEDULE: At PDA diagnosis infants randomized to "late ibuprofen expectant group" will receive blinded placebo. If hemodynamically significant PDA develops, infants now receive open label ibuprofen at an initial dose of 10 mg/kg, then two doses 5 mg/kg each, after 24 and 48 h, slow IV infusion. Signs of a hemodynamically significant PDA include: SIGNS OF PDA + pulmonary hemorrhage ALONE OR SIGNS OF PDA +: Pulmonary edema, plus a large heart on CXR + one of the following: Hypotension, Respiratory failure (due PDA) defined as at least 2 of the following settings: Need for supplemental O2 > 50%; need IMV >40; need for PIP > 20; or need for HFOV.

Initial therapy will be blinded. This group will then be eligible to receive unblinded, open label ibuprofen for a hemodynamically significant PDA include: SIGNS OF PDA + Presence of significant pulmonary hemorrhage ALONE OR SIGNS OF PDA +: Pulmonary edema, plus a large heart on CXR + one of the following: Hypotension, Respiratory failure (not due to something other than PDA) defined as at least two of the following respirator settings: Need for supplemental O2 > 50%; need IMV >40; need for PIP > 20; or need for HFOV.
Receives: Drug: Early ibuprofen
Late Ibuprofen expectant group (placebo)OtherLate ibuprofen expectant group (placebo): Ibuprofen schedule: At PDA diagnosis, infants randomized to "late expectant group" will receive blinded placebo. If hemo-dynamically significant PDA develops, infants now receive open label ibuprofen, initial dose of 10 mg/kg, then 2 doses 5 mg/kg each, after 24 and 48 h, slow IV infusion. Signs of a hemodynamically significant PDA: Signs of PDA + pulmonary hemorrhage alone or Signs of PDA + Pulmonary edema, plus a large heart on CXR + one of the following: Hypotension, Respiratory failure (due to PDA) defined as at least two of the following respirator settings: Need for supplemental O2 > 50%; need IMV >40; need for PIP > 20; or need for HFOV. Infants who had received placebo will ibuprofen for the first time (thus, "late" ibuprofen or expectant).
Receives: Other: Late ibuprofen expectant group (placebo)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Days Spent on Supplemental Oxygen During the First 28 Days.

    Measured: 28 days of life

Secondary outcomes (1)
  1. Number of Participants on Oxygen at 36 Weeks Postmenstrual Age

    Measured: at 36 weeks postmenstrual age

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted5 Dec 2008 (estimated)
  2. Study startNov 2007
  3. Primary completionAug 2010
  4. Study completionFeb 2011

Why it stopped: Lack of availability of IV ibuprofen as of 8/10 due to a manufacturer's recall

Questions about this trial

What is this clinical trial studying?

A study testing Early ibuprofen in people with Patent Ductus Arteriosus, run by University of Miami at 1 site 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 4 inclusion and 6 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: stopped early, as of the sponsor's last update on 5 Feb 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Yes. Results are posted in the registry (first posted 28 Nov 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Days Spent on Supplemental Oxygen During the First 28 Days. (time frame: 28 days of life). 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 NCT00802685, which also lists 1 linked publication.

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 5 Feb 2014.
