Last verified: December 2015
A new method of breath collection for testing for Helicobacter Pylori infection has been developed by Exalenz. In this study, it will be compared to the gold standard- endoscopy results to prove its accuracy.

Condition Intervention Phase
Helicobacter Pylori Infection
Other: Breath Test Collection bags
Phase 3

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Diagnostic
Official Title: Clinical Validation Study to Evaluate Presence of H. Pylori With 13C-Urea Breath Test Using the Dual Mode BreathID® Hp System Compared to Congruent Biopsy Results

Primary Outcome Measures:
  • overall percent agreement [ Time Frame: 21 days ]
    The primary study endpoint is the performance measure (overall percent agreement) in initial diagnosis (presence/ absence of H.pylori) between biopsy results and bag mode breath test.

Secondary Outcome Measures:
  • overall percent agreement [ Time Frame: 21 days ]
    The performance measure (overall percent agreement) in post-therapy diagnosis (presence/ absence of H.pylori) between the Dual Mode BreathID® Hp System when using only one pair of IDkit:Hp™ TWO breath collection bags measured within 9 days and congruent biopsy results

Enrollment: 193
Study Start Date: January 2014
Study Completion Date: February 2015
Primary Completion Date: February 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Initial Diagnosis Cohort
Subjects with clinical indication of H.pylori infection will undergo breath test compared to routine clinical standard of care- endoscopy
Other: Breath Test Collection bags
Breath Collection bags will be used to collect breath of subjects before and after ingestion of 13-C breath test substrate
Other Name: IDKit Two

Detailed Description:
This study will validate a breath collection method by comparing a newly developed breath test kit, IDkit:Hp™ TWO using breath collection bags, to congruent biopsy results (a composite reference standard by analyzing specimens with microbial culture, histological examination and rapid urease test- RUT) in detecting H.Pylori

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Present with clinical indication of H. pylori and candidate for upper endoscopy
  • Have the ability and willingness to sign the Informed Consent Form for initial diagnosis cohort
  • Naive to treatment in the past 18 months
  • No known H.pylori status (no conclusive test results within last 6 months)

Exclusion Criteria:

  • Participation in other interventional trials
  • Antibiotics and/or Bismuth preparations within four (4) weeks prior to breath test
  • PPI (proton pump inhibitors) or H2 blockers within two (2) weeks prior to breath test
  • Pregnant or breastfeeding women
  • Allergy to test substrates
