Trial summary

This study is being done to test how effective cryoablation is in killing cancer cells. Cryoablation uses freezing temperatures to treat cancer. Cryoablation works by creating freezing temperatures within a needle probe. Read more about this study

About this study

This study is being done to test how effective cryoablation is in killing cancer cells. Cryoablation uses freezing temperatures to treat cancer. Cryoablation works by creating freezing temperatures within a needle probe. When this probe is inserted into a cancer, the freezing temperatures are used to try and kill the cancer. Unfortunately, the investigators don't know how well cryoablation works at destroying the cancer. This study will allow us to check to see how well cryoablation works for kidney cancers. After the investigators destroy the kidney cancers using cryoablation, the investigators will followup with you every 5-7 months to make sure the cryoablation worked and that the cancer was destroyed.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • percutaneous cryoablationProcedure or surgery

    All patients will have percutaneous image guided core biopsies of the treatment site and CT or MR imaging at approximately 5-7 months following the cryoablation. They will have repeat imaging every 5-7 months for a period of two years, and if there is evidence of recurrence (ablation zone increase > 5 mm or increased enhancement 15 HU), then repeat biopsy will be obtained. Imaging follow-up past the two year point will be at the discretion of the patient's physicians.

Study groups in NCT01012427
Study groupRoleWhat they receive
Patients with 3.0 cm or smaller renal cancerExperimentalThe interventions in this study are part of clinical care and include percutaneous image-guided biopsy, percutaneous renal tumor cryoablation, CT/MR imaging of the ablation bed, and repeat pathologic sampling of the tumor bed with percutaneous biopsy. The cryoablation is done as the therapeutic intervention in patients with small renal cancer. The CT/MR imaging is done to evaluate the treatment for residual disease after the ablation. The repeat biopsy (e.g. three cores) is done to confirm that the neoplasm has been eradicated. These patients have continued imaging, and if necessary, percutaneous biopsy to ensure no recurrent disease.
Receives: Procedure: percutaneous cryoablation

What is being measured

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

  1. To determine the efficacy rate after percutaneous renal cryoablation.

    Measured: 2 years

Secondary outcomes (4)
  1. To determine the complication rate of percutaneous renal tumor cryoablation.

    Measured: 2 years

  2. To correlate post-treatment imaging parameters of CT/MR with therapeutic cryoablation success.

    Measured: 2 years

  3. To assess the glomerular filtration rate changes associated with percutaneous renal cryoablation.

    Measured: 2 years

  4. To investigate predictors of efficacy after cryoablation.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing percutaneous cryoablation in people with Renal Cancer, run by Memorial Sloan Kettering Cancer Center at 1 site 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 16 inclusion and 6 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 5 Jan 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 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

To determine the efficacy rate after percutaneous renal cryoablation. (time frame: 2 years). 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 5 Jan 2016.
