Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • To be eligible for the present study, patients must meet the following criteria:
  • Able to provide written informed consent
  • Willing to comply with protocol requirements
  • At least 18 years of age
  • Have kidney disease, defined as either CKD II-VI, determined by estimated glomerular filtration rate (GFR) of <90 and derived from serum creatinine measurements, or albuminuria/proteinuria, determined by albumin to creatinine ratio or protein to creatinine ratio of >30mg/gm, or having received a kidney transplant
  • Have at least one kidney lesion identified but incompletely characterized on a non-contrasted US, CT, or MR exam for which the patient's provider recommends follow-up studies or further evaluation with an additional imaging tests.

Who cannot join

  • Patients who meet any of the following criteria will be excluded for enrollment:
  • Critically ill or medically unstable and whose critical course during the observation period would be unpredictable (e.g., chronic obstructive pulmonary disease (COPD) requiring oxygen)
  • Known hypersensitivity to sulfur hexafluoride or to any component of perflutren lipid (Definity®)

  • Active cardiac disease including any of the following:
  • Severe congestive heart failure (class IV in accordance with the classification of the New York Heart Association)
Show all 19Show fewer
  • Unstable angina.
  • Severe arrhythmia (i.e. ventricular tachycardia, flutter fibrillation; ventricular premature complexes occurring close to the preceding T- wave, multifocal complexes).
  • Myocardial infarction within 14 days prior to the date of proposed Definity® administration.
  • Uncontrolled systemic hypertension (systolic blood pressure (BP) >180 mm Hg and/or diastolic BP >100 mm Hg despite optimal medical management
  • Is in an intensive care setting
  • Has an unstable neurological disease (e.g cerebrovascular accident (including transient ischemic attacks (TIAs) within the 3 months before signing of informed consent
  • Has undergone an invasive procedure on kidney lesion (e.g. tissue biopsy, surgery, nonsurgical cytoreductive procedure) since identification of lesion via US without contrast
  • Has any other medical condition or other circumstances that would significantly decrease the chances of obtaining reliable data or of achieving the study objectives such as:
  • Mental illness
  • Drug abuse
  • Female patient who is pregnant or lactating (the possibility of pregnancy has to be excluded by negative serum or urine beta human chorionic gonadotropin results, obtained within 24 hours before the perflutren lipid administration, or on the basis of patient history, e.g.: tubal ligation, hysterectomy or a minimum of 1 year without menses)
  • Obesity that limits obtainment of acceptable images

About this study

Official title: Contrast-enhanced Ultrasound for Complex Kidney Lesion Diagnosis in Patients With CKD (CEUS CKD)

The purpose of this research study is to evaluate contrast-enhanced ultrasound for kidney malignancies

Read the detailed description

This is an investigator-initiated, prospective study designed to evaluate the accuracy of contrast-enhanced ultrasound (CEUS) with microbubble contrast agent (perflutren lipid; Definity®) to identify malignancy in patients with kidney disease, a known risk factor for kidney malignancy, in whom a conventional ultrasound (US) shows an indeterminate cystic kidney lesion.

The primary objective of the study is to estimate the sensitivity of CEUS in diagnosing kidney malignancy in patients with a risk factor for kidney malignancy and compare it to the current gold standard test in this patient population. Secondary analysis will include more optimal contrast-enhanced imaging with computed tomography (CT) or magnetic resonance imaging (MRI) in a subset of patients who can receive these studies. The study outcome will lead to immediate clinical application in patients with chronic kidney disease. Given the cost-effectiveness and adverse event profile, it has excellent potential to become established as first line diagnostics in the general patient population as well.

    Also called Definity®, Microbubble contrast agent

    Dosing per approved package label

Study groups in NCT02684435
Study groupRoleWhat they receive
Perflutren lipid microsphereExperimentalActivate by shaking for 45 seconds using VIALMIX. Use activated product within 5 minutes. Infusion: The recommended infusion dose for activated perflutren is via an IV infusion of 1.3 mL added to 50 mL of preservative-free saline. The rate of infusion should be initiated at 4.0 mL/minute, but titrated as necessary to achieve optimal image enhancement, not to exceed 10 mL/minute per P.I. approval
Receives: Drug: Perflutren lipid microsphere

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Lesions With a Change in Radiologist's Evaluation

    Lesions will be assessed for change in size, calcification, and septation based on Bosniak criteria (I, II, IIF, III, IV) to determine whether a lesion has progressed, regressed, or is stable.

    Measured: Baseline, 1 year

  2. Sensitivity of Qualitative Interpretations of CEUS in Diagnosing Kidney Malignancy

    PRELIMINARY RESULTS of sensitivity of qualitative interpretations of CEUS in diagnosing kidney malignancy in patients with CKD and a suspicious or indeterminate lesion on non-contrasted imaging compared to the truth standard

    Measured: Baseline, 1 year

  3. Specificity of Qualitative Interpretations of CEUS

    PRELIMINARY RESULTS of specificity of qualitative interpretations of CEUS in diagnosing kidney malignancy in patients with CKD and a suspicious or indeterminate lesion on non-contrasted imaging compared to the truth standard

    Measured: Baseline, 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Perflutren lipid microsphere in people with Chronic Kidney Disease and Cystic Kidney Disease, run by University of North Carolina, Chapel Hill at 2 sites in United States.

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 6 inclusion and 19 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 26 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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?

Yes. Results are posted in the registry (first posted 2 Jul 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Lesions With a Change in Radiologist's Evaluation (time frame: Baseline, 1 year). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02684435, which also lists 5 linked publications.

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 26 Sep 2019.
