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 to 80 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patient must have a minimum of 2.0 cm of non-ulcerated, non-inflammatory columnar-lined esophagus or squamous esophageal lined tissue suitable for ablation. A patient may be treated with up to 2 zones of ablation.
  • Patient is 18 to 80 years of age at the time of consent (inclusive).
  • Patient has provided written Informed Consent Form (IFC) using a form that has been approved by the Institution's reviewing IRB/EC.
  • Patient is willing and able to comply with all Clinical Investigation Plan (CIP) requirements.
  • Patient's esophagectomy is clinically necessary due to reasons unrelated to this study.
  • Patient is deemed operable per standard institutional criteria.

Who cannot join

  • Patient has a known history of unresolved drug or alcohol dependency that would limit ability to comprehend or follow instructions related to IFC, post treatment instructions or follow-up guidelines.
  • Patient refuses or is unable to provide written informed consent. - -
  • Patient has or is currently undergoing endoscopic ablation therapy within 4 cm from the proposed treatment area including, but not limited to cryospray therapy, laser treatment, photodynamic therapy, multi-polar electro coagulation, endoscopic mucosal resection, radiofrequency ablation or argon plasma coagulation.
  • Patient has esophageal narrowing limiting access to the intended site of ablation.
  • Patient is undergoing or has recently undergone chemotherapy (within 15 days or WBC below normal by institutional criteria or standards).
  • Patient is undergoing or has recently undergone radiation therapy which involved the esophagus (within 15 days or WBC below normal by institutional criteria or standards).

What participants receive

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

  • Cryoballoon AblationDevice

    Also called CryoBalloon Ablation System, cryoablation

    Device: CryoBalloon Ablation System(TM) C2 Therapeutics Inc. received FDA market clearance for the CryoBalloon Ablation System on September 29, 2010. The System is a Class II device "intended to be used as a cryosurgical tool for the destruction of unwanted tissue in the field of general surgery, specifically for endoscopic applications." (K101825)

Study groups in NCT01293448
Study groupRoleWhat they receive
InterventionExperimentalCryoBalloon ablation of esophageal tissue in patients scheduled for esophagectomy for reasons unrelated to the objective of the study.
Receives: Device: Cryoballoon Ablation

What is being measured

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

  1. Treatment effect

    The primary outcome measure is to evaluate the histological results (depth of injury) of a cryoballoon ablation system.

    Measured: Within 30 days of ablation procedure

Secondary outcomes (2)
  1. Post-ablation symptoms

    A secondary outcome measure is to evaluate post-ablation symptoms - number of participants with adverse events as a measure of safety and tolerability.

    Measured: Within 7 days of ablation procedure

  2. Post procedure pain

    The secondary objective of the study is to determine patient comfort post-procedure. Pain scores are measured on a numerical pain intensity scale.

    Measured: Within 7 days of ablation procedure

Questions about this trial

What is this clinical trial studying?

A study testing Cryoballoon Ablation in people with Barrett's Esophagus and Esophageal Cancer, run by Pentax Medical at 4 sites in 2 countries.

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 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 28 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States, Netherlands. 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.

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?

Treatment effect (time frame: Within 30 days of ablation procedure). 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 28 Apr 2022.
