Clinical Trial Summary

The purpose of this study is to demonstrate the superiority of SonoVue®-enhanced ultrasound versus unenhanced ultrasound for characterization of Focal Liver Lesions using final diagnosis based on histology or combined imaging/clinical data as truth standard.


Description:

Unit of analysis for the outcome measures was the lesion, equivalent to the subject, since each subject had a single lesion that was to be characterized.

Eligibility Inclusion Criteria:

- Male/female.

- Provides written Informed Consent and is willing to comply with protocol requirements.

- Is at least 18 years of age.

- Has at least 1 focal liver lesion (FLL) (target lesion) requiring work-up for characterization. Target lesions may include those:

- Incidentally detected,

- In subjects with chronic hepatitis or liver cirrhosis,

- In subjects with known history of malignancy.

- Is scheduled for surgical removal or biopsy of the target lesion from 24 hours to 30 days after the SonoVue® administration OR

- In case tissue biopsy is not indicated nor surgery planned, is scheduled for or has performed a contrast-enhanced (CE) CT and/or CE-MRI of the target lesion from 30 days to 48 hours prior to or from 24 hours to 30 days after the administration of SonoVue®.

Exclusion Criteria:

- Has an acoustic window insufficient for adequate ultrasound examination of the liver.

- Has a FLL that cannot be identified with unenhanced ultrasound.

- Has received or is scheduled for antineoplastic chemotherapy or an invasive procedure in the time period between test procedures and truth standard assessments which may have modified the target lesion.

- Is receiving any other contrast medium, within the 48 hours before and up to 24 hours following the administration of SonoVue®.

- Has previously been enrolled in and completed this study.

- Known right to left cardiac shunt, bidirectional or transient.

- Has any known allergy to 1 or more of the ingredients of the investigational product (sulfur hexafluoride or to any components of SonoVue®).

- Has any contraindication to 1 of the planned imaging procedures (ultrasound, CT or MRI), e.g., implants, claustrophobia, inadequate medical conditions etc.

- Has received an investigational compound within 30 days before admission into this study.

- Has any medical condition or other circumstances which would significantly decrease the chances of obtaining reliable data, achieving study objectives, or completing the study and/or post-dose follow-up examinations.

- Is determined by the Investigator that the subject is clinically unsuitable for the study.

- Is a pregnant or lactating female. Exclude the possibility of pregnancy by:

- testing on site at the institution serum beta-human chorionic gonadotropin (ßHCG) within 24 hours prior to the start of SonoVue® administration,

- surgical history (e.g., tubal ligation or hysterectomy),

- post menopausal with a minimum 1 year without menses.

Outcome

Type Measure Description Time frame Safety issue
Primary Sensitivity: Percentage of True Positive Lesions Among All Malignant Lesions Per Truth Standard Sensitivity of SonoVue-enhanced ultrasound (SonoVue CE-US) versus unenhanced ultrasound (UE-US) for characterization of malignant focal liver lesions (FLLs), using the diagnosis provided by each of the 3 off-site assessors (blinded to patient data) for the Intent-to-Diagnose (ITD) population. Unit of analysis was the lesion, equivalent to the subject, since each subject had a single lesion that was to be characterized.
True positive: subject with a target lesion characterized as malignant by both ultrasonography and the truth standard.
Truth standard: contrast-enhanced computed tomography (CE CT) and /or contrast-enhanced magnetic resonance imaging (CE-MRI) examination OR tissue pathology/histology from surgical resection/biopsy OR 6-month follow up. Calculated as (number of true positive lesions/number of malignant lesions per truth standard) x 100.
24 hours to 6 months
Primary Specificity: Percentage of True Negative Lesions Among All Malignant Lesions Per Truth Standard Specificity of SonoVue-enhanced versus unenhanced ultrasound for characterization of benign FLLs, using the diagnosis provided by each of the 3 off-site assessors (blinded to patient data) for the ITD population. Unit of analysis was the lesion, equivalent to the subject, since each subject had a single lesion that was to be characterized.
True negative: subject with a target lesion characterized as benign by both ultrasonography and the truth standard.
Truth standard: CE-CT and /or CE-MRI examination OR tissue pathology/histology from surgical resection/biopsy OR 6-month follow up. Calculated as (number of true negative lesions/number of benign lesions per truth standard) x 100.
24 hours to 6 months
Secondary Accuracy: Percentage of True Positive and True Negative Among All Lesions The Accuracy of SonoVue-enhanced versus unenhanced ultrasound for characterization of malignant and benign FLLs, using the diagnosis provided by each of the 3 off-site assessors (blinded to patient data) for the ITD population Unit of analysis was the lesion, equivalent to the subject, since each subject had a single lesion that was to be characterized.
True positive: subject with a target lesion characterized as malignant by both ultrasonography and the truth standard.
True negative: subject with a target lesion characterized as benign by both ultrasonography and the truth standard.
Truth standard: CE-CT and /or CE-MRI examination OR tissue pathology/histology from surgical resection/biopsy OR 6-month follow up. Calculated as (number of true positive and true negative lesions/number of total lesions per truth standard) x 100.
24 hours to 6 months
Secondary Positive Predictive Value (PPV): Percentage of True Positive Lesions Among All Malignant Lesions Per Ultrasound Positive Predictive Value of SonoVue-enhanced versus unenhanced ultrasound for characterization of FLLs, using the diagnosis provided by each of the 3 off-site assessors (blinded to patient data) for the ITD population. Unit of analysis was the lesion, equivalent to the subject, since each subject had a single lesion that was to be characterized.
True positive: subject with a target lesion characterized as malignant by both ultrasonography and the truth standard.
Truth standard: CE-CT and /or CE-MRI examination OR tissue pathology/histology from surgical resection/biopsy OR 6-month follow up. Calculated as (number of true positive lesions/number of malignant lesions per ultrasound) x 100.

Unit of analysis was the lesion, equivalent to the subject, since each subject had a single lesion that was to be characterized.
True negative: subject with a target lesion characterized as benign by both ultrasonography and the truth standard.
Truth standard: CE-CT and /or CE-MRI examination OR tissue pathology/histology from surgical resection/biopsy OR 6-month follow up. Calculated as (number of true negative lesions/number of benign lesions per ultrasound) x 100.

Truth standard: CE-CT and /or CE-MRI examination OR tissue pathology/histology from surgical resection/biopsy OR 6-month follow up. Calculated as (number of correctly characterized lesions/number of lesions per truth standard) x 100.
