Trial summary

There is no bedside imaging technique that can quantify dynamic bowel perfusion with high soft tissue contrast and sensitivity in necrotizing enterocolitis (NEC). Our goal is to assess the feasibility of utilizing contrast-enhanced ultrasound (CEUS) in bedside monitoring of bowel perfusion in NEC. Read more about this study

About this study

Official title: Evaluation of Bowel Perfusion With Contrast-Enhanced Ultrasound in Necrotizing Enterocolitis

There is no bedside imaging technique that can quantify dynamic bowel perfusion with high soft tissue contrast and sensitivity in necrotizing enterocolitis (NEC). Our goal is to assess the feasibility of utilizing contrast-enhanced ultrasound (CEUS) in bedside monitoring of bowel perfusion in NEC. Patients with suspected or diagnosed NEC will be recruited for the study. Following parental consent, the subject will undergo CEUS, performed separately from any clinically indicated conventional US, in the ICU. Subjects will be scanned with CEUS at two different time-points (at the time NEC is first suspected or diagnosed and at time of MRI scan). The CEUS scans will be interpreted by the sponsor-investigator.

The study will be conducted at one site, The Children's Hospital of Philadelphia. It is expected that up to 100 subjects will be enrolled per year, for up to two years, for a total enrollment of up to 200 subjects.

Read the detailed description

Early detection of ischemia and necrotic bowel which leads to perforation is vital in improving morbidity and mortality associated with NEC. Abdominal radiography, the standard imaging algorithm for monitoring of NEC, has a low sensitivity of 40% in the diagnosis of severe NEC with necrotic bowel. There is a dire need to introduce better imaging tools such as CEUS to the clinical setting that can detect NEC at an early stage and prompt therapeutic implementation. CEUS enables safe, serial monitoring of dynamic quantification of bowel perfusion at the bedside.

Sulfur hexafluoride lipid-type A microspheres (LumasonTM, Bracco Inc) is an FDA-approved ultrasound contrast agent. The study duration per subject will be approximately 15 minutes including the time to prepare LumasonTM contrast agent and perform the CEUS, as well as the 60 minute monitoring period after the first and second injection of LumasonTM. CEUS will be performed at the time of suspected or diagnosed NEC, and at the time of surgery (for subjects undergoing surgery as part of clinical care) or at short-term follow-up of clinical condition (approximately 1 week after the first scan) for a total of two CEUS exams of 1 hour and 15-minute duration each.

Injection of LumasonTM contrast agent will be performed via the existing peripheral intravenous line or central line using the FDA-recommended dose of up to 0.03 mg/kg. Contrast-agent injection will be performed twice per CEUS scan to ensure image quality and test reproducibility. In the case of more stable patients without an IV line, a peripheral IV line will be started to conduct the investigational CEUS. Two bolus injections will performed to evaluate for dynamic bowel perfusion and several 2-minute cine clips as well as static images will be acquired during the exam.

Qualitative analysis with visual assessment and quantitative analysis of the acquired CEUS scans will be performed and interpreted by the PI. The scans will be assessed for diagnostic quality of images, artifacts encountered, and the presence of additional contributory diagnostic information.

    Injection of Sulfur hexafluoride lipid-type A microspheres (Lumason) contrast agent will be performed via the existing peripheral intravenous line using the FDA-recommended dose of 0.03 mg/kg. Two bolus injections will be performed to evaluate for dynamic bowel perfusion and several 2-minute cine clips as well as static images will be acquired during the exam.

Study groups in NCT03549507
Study groupRoleWhat they receive
Contrast-enhanced UltrasonographyExperimentalIntravenous administration of contrast agent Sulfur hexafluoride lipid-type A microspheres before performing contrast-enhanced ultrasound (CEUS). In pediatric patients, after reconstitution 0.03 mL per kg is administered intravenously. The weight-based dose of 0.03 mL per kg will be repeated one time during a single examination. Following each injection, an intravenous flush of 0.9% Sodium Chloride is injected. The study duration per subject will be approximately 15 minutes including the time to prepare the contrast agent and perform the CEUS, as well as the 60 minute monitoring period after the first and second injection (if there are two injections of contrast) of the contrast agent.

What is being measured

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

  1. Early Detection of Altered Bowel Perfusion Using CEUS

    Comparison of bowel perfusion between normal subjects (those with suspected or at risk of necrotizing enterocolitis but turn out to be normal on imaging and clinical evaluation) versus NEC patients

    Measured: 2 years

Secondary outcomes (1)
  1. Number of Participants With Completed CEUS Exams, Categorized by Diagnostic-Quality Scoring System

    Scoring system of non-diagnostic (1), moderate artifacts degrading diagnostic quality (2), mild artifacts without degradation of diagnostic quality (3), and diagnostic (4).

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Sulfur hexafluoride lipid-type A microspheres in people with Necrotizing Enterocolitis of Newborn and Bowel Ischemic, run by Children's Hospital of Philadelphia 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 5 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: stopped early, as of the sponsor's last update on 12 Nov 2024. 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.

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?

Yes. Results are posted in the registry (first posted 12 Nov 2024). 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?

Early Detection of Altered Bowel Perfusion Using CEUS (time frame: 2 years). 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 NCT03549507, 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 12 Nov 2024.
