About this study

Official title: Contrast Enhanced Ultrasound (CEUS) Detection of Microvascular Perfusion Impairment in COVID-19 Pediatric Patients

Initial data from COVID-19 patients suggests that one of the primary causes of death is significant endothelial injury leading to blood clotting and impaired multiorgan microvascular perfusion. The current study uses a safe, convenient bedside imaging tool called contrast-enhanced ultrasound (CEUS) to estimate the extent of microvascular perfusion impairment in the heart, kidneys and/or brain of COVID-19 pediatric patients in vivo and assess the significance of imaging findings by correlating to clinical outcomes.

This pilot study will be conducted at one site, The Children's Hospital of Philadelphia. The investigators plan to enroll and evaluate 30 patients.

Read the detailed description

The current study uses a safe, convenient bedside imaging tool called contrast-enhanced ultrasound (CEUS) to measure the extent of microvascular perfusion impairment in the heart, kidneys and/or brain of COVID-19 pediatric patients and, as exploratory analysis, to assess the significance of imaging findings by correlating to clinical outcomes.

Sulfur hexafluoride lipid-type A microspheres (LumasonTM, Bracco Inc) is an FDA-approved ultrasound contrast agent. Contrast-enhanced ultrasound scan with a duration of approximately 15 minutes will be performed when a COVID-19 diagnosis has been made (or is highly suspected) according to established clinical procedures. One CEUS will be performed per patient, with up to 2 intravenous injections of the contrast agent. The dosing plan will be weight-adjusted, based on a dose of 0.03 mL/kg (with a maximum dose of 2.4 mL per injection). Organ perfusion will be evaluated in the heart, kidneys, and/or brain. Clinical outcomes during hospital stay will be collected for correlation to CEUS-based measures.

Conditions: Covid19, Multisystem Inflammatory Syndrome in Children (MIS-C)
Being tested: Sulfur hexafluoride lipid-type A microspheres
Keywords: Ultrasound, Contrast-enhanced ultrasound
Medical subject headings: COVID-19, pediatric multisystem inflammatory disease, COVID-19 related

What participants receive

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

Sulfur hexafluoride lipid-type A microspheresDrug
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 NCT04640038
Study group	Role	What they receive
Contrast-enhanced Ultrasonography	Experimental	Intravenous 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. Receives: Drug: Sulfur hexafluoride lipid-type A microspheres

What is being measured

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

Estimate the Proportion of Patients With Normal Perfusion Versus Area(s) of Hypoperfusion in Heart, Kidneys and/or Brain
Assess microvascular perfusion of the heart, kidneys and/or brain using CEUS in patients with confirmed or probable diagnosis of COVID-19.
A sufficient diagnostic quality to analyze the ultrasound examination was accomplished in three out of four patients.
Measured: 15 minutes.

Limitations and caveats (from the sponsor): Since this is an exploratory study with limited sample size, no absolute conclusions related to true microvascular impairment in MIS-C can be drawn. Whether heterogeneous results are due to the small sample, the timing of CEUS with regard to disease evolution and treatment, the use of concomitant medications, such as furosemide, a milder course of the disease, or the differing pathophysiology between MIS-C and primary COVID-19 infection in adults requires additional exploration.

Questions about this trial

What is this clinical trial studying?

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 1 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 30 Jul 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 8 Mar 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?

Estimate the Proportion of Patients With Normal Perfusion Versus Area(s) of Hypoperfusion in Heart, Kidneys and/or Brain (time frame: 15 minutes.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
