WavSTAT® Optical Biopsy System to Target Esophageal Biopsies

April 12, 2016 updated by: SpectraScience

A Prospective Evaluation of the WavSTAT® Optical Biopsy System to Target Esophageal Biopsies: An Adjunctive Tool to Assist the Endoscopist to Identify Dysplasia or Cancer

The purpose of this study is to demonstrate the clinical utility of the WavSTAT Optical Biopsy System as an adjunctive tool to improve the endoscopist's clinical sensitivity to identify dysplasia or cancer in the esophagus.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

In the clinical portion of this prospective study, the algorithm developed in the preclinical evaluation will be blindly tested using the pathologists' assessment of the biopsies as a gold standard to determine the clinical sensitivity and specificity of the WavSTAT Optical Biopsy System to identify dysplastic or cancerous tissue in the esophagus. In addition, the endoscopist's unaided clinical sensitivity and specificity to identify dysplasia or cancerous tissue will also be determined by recording the endoscopist's visual assessment of whether the physical biopsy has dysplasia or cancer or does not have dysplasia or cancer prior to performing the biopsy The endoscopist's assessment will be correlated and compared with the pathologist's interpretation. The clinical utility of the WavSTAT System to improve the endoscopist's clinical sensitivity to identify dysplasia or cancer in the esophagus will be evaluated by testing the hypothesis that the sensitivity of a WavSTAT-assisted endoscopic examination improves that of standard endoscopy alone.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients with Barrett's esophagus

Description

Inclusion Criteria:

  • The patient is between 18 and 80 years of age.
  • The patient is willing to sign an informed consent form.
  • The patient is a candidate for endoscopic examination
  • Female patients of child-bearing age, uncertain of pregnancy status, must have a negative pregnancy test.

Exclusion Criteria:

  • The patient has congenital deformities, which preclude a physical biopsy procedure during endoscopy.
  • The patient is pregnant or nursing by admission.
  • The patient has other contraindications for physical biopsy.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Determine sensitivity/specificity to identify dysplasia/cancer in the esophagus WavSTAT System alone, endoscopist alone/combination of WavSTAT and endoscopist. Sensitivity of the endoscopist will be compared to combination of endoscopist and WavSTAT.
Time Frame: 9-15 months estimated
9-15 months estimated

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 1, 2008

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
October 1, 2012

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
