|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||424 participants|

|Official Title:||A Phase 3 Multicentre, Randomised, Comparative Study of the Efficacy and Safety of the Ultrasound Contrast Agents Sonazoid™ and SonoVue® in Subjects With Focal Liver Lesions Undergoing Pre- and Post-Contrast Ultrasound Imaging|
|Actual Study Start Date :||May 11, 2014|
|Actual Primary Completion Date :||April 9, 2015|

Participants will receive single intravenous (I.V) bolus injection of Sonazoid™ 0.12 microliter (µL) microbubbles (MB)/kilogram (kg) body weight.
Single Dose of Sonazoid™ 0.12 µL MB/kg as I.V. injection.
Active Comparator: SonoVue®
Participants will receive single I.V bolus injection of SonoVue® 2.4 milliliter (mL).
Single Dose of SonoVue® 2.4 mL as I.V. injection.
- Percentage of Participants With Accuracy Improvement in Post-Contrast Versus Pre-Contrast Ultrasound (US) Examination for Diagnosis of the Target Lesion as Malignant or Benign Against the Reference Diagnosis (RD)/Standard of Truth [ Time Frame: Pre-administration up to 15 minutes post-administration ]Accuracy improvement was calculated by the number of participants with improved diagnoses from the pre-contrast diagnosis to the post-contrast diagnosis divided by the total number of participants, multiplied by 100. Assessments were done by 3 blinded readers. Efficacy population which included all participants who received Sonazoid™ or SonoVue®, for whom pre-contrast & post-contrast images were recorded, & for whom there was a reference standard contrast-enhanced computed tomography (CECT)/contrast-enhanced magnetic resonance imaging (CE-MRI) examination or biopsy.
- Number of Lesions Detected by Post-Contrast US Relative to Number of Lesions Detected by Pre-Contrast US (Both by Blinded Readers[BR]) and Number of Lesions Detected by Post-Contrast US (by BR) Relative to Number of Lesions Detected by RD (Investigators) [ Time Frame: Pre-administration up to 15 minutes post-administration ]For the cases that can be assessed by the blinded readers both pre- and post-contrast, differences were calculated between the Sonazoid™ and SonoVue® groups in the number of lesions detected during whole-liver imaging (post-contrast minus pre-contrast). The differences were also calculated between the Sonazoid™ and SonoVue® groups in the number of lesions (post-contrast minus reference diagnosis) detected during whole-liver imaging.
- Number of Participants With Diagnostic Confidence (Evaluated by Blinded Readers) in Pre-Contrast and Post-Contrast Ultrasound Examination Results [ Time Frame: Pre-administration up to 15 minutes post-administration ]Confidence in diagnoses from the pre- and post-contrast ultrasound examinations was evaluated based on 4-point scale: 0-Unknown (cannot make a judgement on level of confidence), 1- Not confident (another examination was required), 2- Probable (Would have more confidence if another diagnostic imaging test such as MRI or CT was performed), 3- Definite (Sufficient confidence to the extent that another diagnostic imaging test such as MRI or CT was unnecessary).
- Percentage of Participants With Accuracy Improvement in Post-contrast Versus Pre-contrast Ultrasound Examination for Lesion-Specific Diagnoses of the Target Lesion Against the Reference Diagnosis/Standard of Truth [ Time Frame: Pre-administration up to 15 minutes post-administration ]The accuracy improvement was calculated by the number of participants with improved diagnoses from the pre-contrast diagnosis to the post-contrast diagnosis divided by the total number of participants, multiplied by 100. Assessment was performed by 3 blinded readers.
