Trial summary

Despite improvements in neonatal care, birth asphyxia in term newborns remains a serious condition causing significant mortality and long-term morbidity, including cerebral palsy and mental retardation. Currently, no treatment exists to repair brain injuries secondary to neonatal asphyxia. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 0 minutes to 48 hours
  • All sexes
  • No healthy volunteers
  • Child

Who may be able to join

  • Male and female asphyxiated newborns meeting the criteria for induced hypothermia:
  • Gestational age ≥ 36 weeks and birth weight ≥ 1800 g
  • Evidence of fetal distress, such as a history of an acute perinatal event, a cord pH ≤ 7.0 or base deficit ≤ - 16 mEq/L
  • Evidence of neonatal distress, such as an Apgar score ≤ 5 at 10 minutes, a postnatal blood gas pH obtained within the first hour of life ≤ 7.0 or base deficit ≤ - 16 mEq/L, or a continued need for ventilation initiated at birth and continued for at least 10 minutes
  • Evidence of moderate to severe neonatal encephalopathy by an abnormal neurological exam and/or an amplitude-integrated electroencephalogram (aEEG) These newborns will receive whole-body cooling to an esophageal temperature of 33.5°C, initiated within the first 6 hours of life, continued for 72 hours, and then they were slowly rewarmed using standard protocol .
  • Evidence on a brain MRI performed on day 2 of life (while they are treated with hypothermia) of any type of brain parenchymal injury patterns typically encountered in asphyxiated newborns.
  • If they meet the criteria for hypothermia treatment and demonstrate brain injury on day 2 of life, they will be randomized to sildenafil or placebo treatment.

About this study

Official title: Sildenafil Administration to Treat Neonatal Encephalopathy (SANE) and Repair Brain Injury Secondary to Birth Asphyxia: A Randomized, Double-blind, Placebo-controlled Pilot Phase Ib Study

Despite improvements in neonatal care, birth asphyxia in term newborns remains a serious condition causing significant mortality and long-term morbidity, including cerebral palsy and mental retardation. Currently, no treatment exists to repair brain injuries secondary to neonatal asphyxia. The only available treatment for this condition is hypothermia that may prevent but not repair the development of brain injury. The success of this therapy is limited.

Sildenafil already is used with some newborns for other purposes (i.e., persistent pulmonary hypertension), but, surprisingly, its effect on the newborn brain has never been studied systematically. The findings of the investigators in the rat model of term neonatal encephalopathy demonstrated that the administration of sildenafil following asphyxia promotes brain injury recovery. Thus, the investigators hypothesize that sildenafil may improve neurodevelopmental outcome in term asphyxiated newborns, in whom hypothermia treatment has failed to prevent the development of brain injury.

Read the detailed description

Before being able to run a large multicenter randomized trial to prove this hypothesis, the investigators need to run a phase Ib pilot trial to ensure the feasibility and safety of using sildenafil in this population of newborns. Thus, for this phase Ib study, the investigators hypothesize that sildenafil can be safely used with term asphyxiated newborns treated with hypothermia. The investigators will test this hypothesis with the following specific aims:

  1. Safety (primary): ensure that sildenafil can be safely used in asphyxiated newborns treated with hypothermia;
  2. Tolerability (secondary): study the pharmacokinetics and pharmacodynamics of sildenafil in these newborns;
  3. Efficacy (exploratory): determine whether sildenafil improves neurodevelopment at 2 years of age, decreases brain injury on day 30 of life and decreases neuroinflammation.

What is being measured

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

  1. Serious adverse events

    Close monitoring for adverse events such as death, hypotension, persistent pulmonary hypertension, altered renal or hepatic function, etc to assess the safety of sildenafil

    Measured: Day 1 to 14 of life

Secondary outcomes (1)
  1. Plasmatic concentrations of sildenafil and N-desmethyl sildenafil

    To determine the tolerability of sildenafil (pharmacokinetics/pharmacodynamics)

    Measured: Day 2 to 10 of life

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Sildenafil and Ora-Blend in people with Neonatal Encephalopathy, run by McGill University Health Centre/Research Institute of the McGill University Health Centre at 1 site in Canada.

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 7 inclusion and 5 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 8 Feb 2022. 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 Canada. 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 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.

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?

Serious adverse events (time frame: Day 1 to 14 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 NCT02812433, which also lists 2 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 8 Feb 2022.
