Renal Cell CarcinomaPhase 2NCT01062178
Efficacy of Ultrasound Contrast Agent to Assess Renal Masses
A Phase 2 study testing Definity in people with Renal Cell Carcinoma, run by University Health Network, Toronto at 1 site in Canada.
Trial summary
Patients with an incidentally discovered small renal masses (SRM) < 4 cm in diameter are included. All patients will undergo biopsy for tissue diagnosis. Most patients will be followed by imaging. Study intervention includes low MI US to be performed following both bolus and infusion injection of Definity contrast. Read more about this study

About this study
Official title: The Comparison of Accuracy of Contrast Enhanced Ultrasound on Diagnosis of Small Renal Masses and Distinguishing Renal Cell Carcinomas From Other Renal Masses, With Biopsy
Patients with an incidentally discovered small renal masses (SRM) < 4 cm in diameter are included. All patients will undergo biopsy for tissue diagnosis. Most patients will be followed by imaging. Study intervention includes low MI US to be performed following both bolus and infusion injection of Definity contrast. Presence and absence of vascularity, pattern of vascularity, and TIC values will be correlated with the final pathology to find features differentiating benign from malignant masses.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Patients with an incidentally discovered small renal masses (SRM) < 4 cm in diameter are included. All patients will undergo biopsy for tissue diagnosis. Most patients will be followed by imaging. Study intervention includes low MI US to be performed following both bolus and infusion injection of Definity contrast. Presence and absence of vascularity, pattern of vascularity, and TIC values will be correlated with the final pathology to find features differentiating benign from malignant masses.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Definity in people with Renal Cell Carcinoma, run by University Health Network, Toronto at 1 site in Canada.
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 1 inclusion and 0 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 8 Mar 2016. 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 Canada. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
biopsy (time frame: 12 to 18 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Mar 2016; AzTrials last refreshed its copy on 8 Nov 2026.
