Contrast Ultrasound for Pediatric Trauma - Comparative Evaluation (CAPTURE Study)

This multicenter study aims to evaluate the accuracy of contrast-enhanced ultrasound (CEUS) in diagnosing abdominal solid organ injuries in pediatric patients. Up to 130 subjects will complete the study across approximately 5-10 sites in the US, with up to 30 patients in the training phase (3 per site) and 100 patients in the treatment phase of the study. All subjects will have had a CT scan as part of standard of care, confirming at least one solid organ abdominal injury. The study procedure will occur within 48 hours from time of injury. All subjects will have an abdominal ultrasound without contrast, followed by a contrast-enhanced ultrasound using the contrast agent Lumason. Ultrasound and contrast-enhanced ultrasound results will be compared to the CT scan results. The CT and ultrasound scans will be read locally and will undergo central review.

Study Overview

• Status: Completed
• Conditions: Abdominal Injury
• Intervention / Treatment: Drug: Lumason

Detailed Description

This is an interventional study which proposes to evaluate the accuracy of contrast-enhanced ultrasound (CEUS) in diagnosing abdominal solid organ injuries in pediatric trauma patients. Up to 130 subjects will be enrolled across approximately 5 to 10 sites in the US. Each site, including the coordinating center, will undergo the training phase; each site will enroll 3 participants in this phase successfully prior to entering the treatment phase. All subjects will have had a Computerized Tomography (CT) scan as part of standard of care, confirming at least one solid organ abdominal injury. All subjects will have an abdominal ultrasound without contrast, followed by a contrast-enhanced ultrasound using the contrast agent Lumason. Ultrasound and contrast-enhanced ultrasound results will be compared to the CT scan results. The study procedures will take place within 48 hours of injury. At conclusion of enrollment of all subjects a centralized review of CT vs. CEUS will occur to compare to real-time readings.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: All Study Participants; All subjects will have an abdominal non-contrast ultrasound performed. Lumason will then be administered at a dose of 0.03mL/kg up to a maximum dose of 2.4mL and a contrast-enhanced ultrasound will be performed. The dose will be given twice, for a total maximum dose per subject of 4.8mL	Drug: Lumason; Lumason will be administered at a dose of 0.03 mL/kg up to a maximum dose of 2.4mL injected into a peripheral intravenous catheter. An abdominal contrast enhanced ultrasound will be performed to look for solid organ injury. The will be given twice during the intervention, for a total maximum dose per subject of 4.8mL.; Other Names: SonoVue

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall CEUS/CT Concordance for all study participants	A patient is classified as having a "concordant" assessment if each organ identified by CT with injuries is exactly identified by CEUS, regardless of injury grade, by the local study site reviewer. Otherwise, a patient is classified as having a "discordant" assessment.	At the time the CEUS is performed, within 48 hours of injury

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Organ-specific CEUS/CT Concordance	For each organ, a patient's organ is classified as having a "concordant" assessment if the presence or absence of an injury as identified by CT is exactly identified by CEUS. Otherwise, a patient is classified as having a "discordant" assessment.	At the time the CEUS is performed, within 48 hours of injury
Grade-specific Overall CEUS/CT Concordance	A patient is classified as having a "concordant" assessment if each organ identified by CT with injuries is exactly identified by CEUS, AND within 1 grade of the injury as identified by CT. Otherwise, a patient is classified as having a "discordant" assessment.	At the time the CEUS is performed, within 48 hours of injury
Peritoneal Fluid CEUS/CT Concordance	A patient is classified as having a "concordant" assessment if the absence or presence of peritoneal fluid identified by CT is also exactly identified by CEUS. Otherwise, a patient is classified as having a "discordant" assessment.	At the time the CEUS is performed, within 48 hours of injury.
Real-time/Centralized CEUS Concordance	A patient is classified as having a "concordant" assessment if the absence or presence of injury for each organ identified by 'real-time' CEUS with injuries is also exactly identified by centralized interpretation of CEUS images.	At the time the CEUS is performed, within 48 hours of injury.
