Cryotherapy -BEATS-RF Ablation Trial

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01882478
Recruitment Status : Active, not recruiting

Brief Summary:
The purpose of this study is to determine whether cryotherapy is effective in the treatment of persistent high grade dysplasia (HGD) or early esophageal adenocarcinoma (IMCA) in patients who have not responded to radiofrequency ablation (RFA).

Condition or disease
Barrett's Esophagus With Persistent Dysplasia or Early Esophageal Adenocarcinoma Post Radio Frequency Ablation

Study Type : Observational
Estimated Enrollment : 15 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: CryoSpray Ablation for Barrett's Esophagus After Treatment Failure With Serial RadioFrequency Ablation
Study Start Date : June 2013
Estimated Primary Completion Date : June 2021
Estimated Study Completion Date : June 2021

failure to respond to RF ablation
patients undergoing endoscopic RF ablation therapy with persistent BE with HGD or IMCA despite 2 or more serial RF ablation treatment sessions

Primary Outcome Measures :
  1. Response [ Time Frame: 2 years ]
    To assess efficacy of achieving elimination of dysplasia in patients with RFA-refractory BE with HGD or IMCA

Secondary Outcome Measures :
  1. Predictors of response [ Time Frame: 2 years ]
    To identify potential predictors of CE-D and CE-IM in patients requiring rescue CSA treatment after failed RFA therapy

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
patients with persistent BE with HGD or IMCA despite 2 or more serial RF ablation treatment sessions in a cohort of patients undergoing endoscopic therapy.

Inclusion Criteria:

  • Age > 18 years old
  • Able to provide informed consent
  • Patients with unifocal or multifocal BE with HGD or IMCA who have failed at least 2 serial RFA therapy.
  • Patients who refused esophagectomy or deemed inoperable or whose BE dysplasia is not amenable to endoscopic mucosal resection (EMR) treatment alone due to: (1) extensive multifocal lesions (2) severe coagulopathy or any medical condition deemed high risk for EMR (3) patient refuses EMR
  • Patients with a nodular BE lesions may undergo clinically-indicated EMR and still be eligible for enrollment as long as they have BE-HGD lesion/s that are still candidate for ablative treatment

Exclusion Criteria:

  • Age younger than 18 years old
  • Life expectancy less than 12 months
  • Pregnancy
  • Presence of esophageal varices
  • Esophageal stricture precluding passage of an endoscope and suction tubing
  • Any procedure that has impeded normal gastric emptying or limited gastric volume distention, including but not limited to gastric bypass, stomach stapling, gastrojejunostomy or any disease state has significantly reduced the elasticity in the GI tract (e.g. Marfan's syndrome, Scleroderma or any Connective Tissue Disease)
  • Esophageal cancer (T2 and above)
