Clinical Trial Summary

This study proposes to evaluate the accuracy of contrast-enhanced ultrasound (CEUS) in diagnosing abdominal solid organ injuries in pediatric patients. 146 subjects will be enrolled across approximately 8 sites in the US. 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.


Description:

This is an interventional study proposes to evaluate the accuracy of contrast-enhanced ultrasound (CEUS) in diagnosing abdominal solid organ injuries in pediatric patients. 146 subjects will be enrolled across approximately 8 sites in the US. 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.

Intervention

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.

Outcome

Type Measure Description Time frame Safety issue
Primary Proportion of Patients for Whom All Organs Identified by CT With Injuries Are Also Identified by CEUS, Regardless of Injury Grade. During analysis, results of contrast enhanced ultrasound will be compared to results of CT scan that was performed as part of clinical care to determine if the organs identified as injured by CT were also identified as injured by CEUS. At the time the CEUS is performed, within 48 hours of injury.
Secondary For Each Organ, the Proportion of Patients for Whom the Organ is Identified by CT and CEUS as Injured (Regardless of Grade). Results will be categorized by organ and analyzed to determine the percentage of injuries for each organ that were identified by CT that were also identified by CEUS. At the time the CEUS is performed, within 48 hours of injury.
Secondary Proportion of Injuries Identified by CEUS Which Are Within 1 Grade of the Injury Identified by CT. The grade for the severity of the injury as determined by CEUS will be compared to the grade for the severity of the injury as determined by CT scan. At the time the CEUS is performed, within 48 hours of injury.
Secondary Proportion of Patients Where the Absence or Presence of Peritoneal Fluid Identified by CT is Also Identified by CEUS. The presence or absence of peritoneal fluid as determined by CEUS will be compared to the presence or absence of peritoneal fluid as determined by CT scan. At the time the CEUS is performed, within 48 hours of injury.
Secondary Proportion of Patients With Agreement Between 'Real-time' and Centralized Interpretation of CEUS Images. The contrast-enhanced ultrasounds will be re-read by a centralized reviewer and the results compared to those from the real-time reading. At the time the CEUS is performed, within 48 hours of injury.
