About this study

To compare the effectiveness of rectal vs. intravenous paracetamol in the medical treatment of significant PDA in neonates.

Read the detailed description

The ductus arteriosus (DA) is a vascular channel between the aorta and the pulmonary artery (PA). It diverts blood away from the lungs and directs it to systemic circulation during pregnancy.1 Therefore, its opening is necessary for the life of the fetus, but after birthing its closure is necessary. During pregnancy, the DA and the placenta produce vasodilators that keep the DA open, but, in term infants, as they are born, the number of contractile factors increases, the sensitivity of DA to prostaglandins decreases, and sensitivity to oxygen increases which causes ductal constriction. In contrast, in premature infants, DA sensitivity to vasodilators increases, although this sensitivity decreases with increasing neonatal age. Patent ductus arteriosus (PDA) is a major life-threatening problem in premature and low birth weight infants. In 60% to 70% of preterm and low birth weight infants, the DA remains open.

The choice of treatment depends on factors like PDA size, patient age, health status, and symptomatology. The types of treatment for Patent Ductus Arteriosus (PDA) include medical treatment involving medications to encourage closure, catheter-based intervention using minimally invasive procedures to block the ductus arteriosus, and surgical closure through a small chest incision.

Regarding the medical treatment, non-specific cyclooxygenase (COX) inhibitors (indomethacin, ibuprofen). These drugs work by inhibiting cyclooxygenase and stopping the synthesis of prostaglandins E2, F2a, I2, and thromboxane A2. This is followed by vascular smooth muscle constriction, local ischemia, angiogenesis, DA intima regeneration, wall fibrosis, and DA closure. Ibuprofen and indomethacin are standard treatments for PDA closure, but due to possible side effects in the gastrointestinal tract, kidney, chronic lung disease, thrombocytopenia, and hyperbilirubinemia, it is preferable to use acetaminophen/paracetamol with fewer side effects.

In addition, PDA closure may be associated with complications such as chronic lung disease, heart disease, neurodevelopmental disorder, and retinopathy of prematurity (ROP).1 Therefore, it is desirable to prescribe drugs with no contraindications and fewer side effects to close PDA. The effect of acetaminophen/paracetamol on PDA closure was first reported in 2011,6 and extensive studies on its effects have been performed since then.6,7,8 Due to its properties such as safety, availability, low price, lack of side effects related to nonsteroidal anti-inflammatory drugs (NSAIDs), and the fact that this drug has been used as an anti-inflammatory and analgesic treatment in infants for many years, acetaminophen will gradually replace NSAIDs for PDA medical closure.

Surgery for PDA closure is performed when treatment with COX inhibitors is contraindicated or unsuccessful.

Rectal administration of paracetamol involves inserting a suppository into the rectum for absorption into the bloodstream, offering the advantages of being less invasive and suitable for limited vascular access, while potentially causing slower and variable absorption; intravenous (IV) paracetamol, delivered directly into the bloodstream through a vein, ensures accurate dosing, rapid absorption, and consistent drug delivery, but requires established intravenous access and vigilant monitoring for potential adverse effects, with both methods having potential systemic side effects and varying efficacy in promoting PDA closure.

What participants receive

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

  • ParacetamolDrug

    All cases will be randomized simply by opaque closed envelop and treated with either rectal or intravenous paracetamol according to the following doses.

    • Rectal dose
    • Rectal paracetamol at a dose of 25 mg/kg body weight with started and then continued at a dose of 15 mg/kg body weight every 8 hours for 3 days (ten doses in total) in neonates weighing more than 1000 gm.11
    • The patient's weight is less than 1000 gm, the initial dose was 15 mg/kg body weight, and the suspense doses are 7.5 mg/kg body weight every 8 hours for 3 days (10 doses in total).11
    • Intravenous dose
    • Intravenous paracetamol dose 15 mg/kg body weight every 6 hours for 3 days (12 doses in total).12
    • After the 3-day follow up echocardiogram will be done.12 This will be the end of randomization for the purpose of the study.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Paracetamol in people with Patent Ductus Arteriosus, run by Soha mahmoud Hussien mahdy.

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 1 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 13 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Soha Ma Hussein, Msc. student (+2001061554768, sohamahdy25@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Assessment the rate of efficiency of Rectal and Intravenous Paracetamol in The Treatment of Patent Ductus Arteriosus (PDA) in Neonates (time frame: 1 year). 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 NCT06256211, which also lists 2 linked publications.

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