Clinical Trial Summary

The purpose of this study is to collect human breath samples for use in a validation study intended to demonstrate equivalent clinical performance measures of new ABCA2 GIRMS (Automated Breath Carbon Analyzer-2 Gas Isotope Ratio Mass Spectrometer) instruments to the currently FDA-approved ABCA GIRMS (Automated Breath Carbon Analyzer Gas Isotope Ratio Mass Spectrometer) system. ABCA GIRMS systems are used to analyze the ratio of 13CO2 to 12CO2 in patient breath samples during the GEBT (Gastric Emptying Breath Test) procedure.

Description:

In this study the participants will be administered the FDA-approved GEBT test, which involves collecting breath samples prior to and after consumption of a non-radioactive carbon stable isotope (13C) labeled test meal. Breath samples will be collected at times consistent with FDA approved labeling. Participant's breath samples will be analyzed on the currently approved ABCA GIRMS and on the new ABCA2 GIRMS instruments. The values collected from both systems will be used to determine the clinical diagnostic agreement at each individual time points and percent agreement in diagnosis between the approved ABCA GIRMS and the new ABCA2 GIRMS.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Diagnostic agreement at each individual timepoints	Gastric emptying rates (kPCD) values compared between the validated ABCA GIRMS system and the new ABCA2 GIRMS systems for each GEBT post meal collection timepoint (45, 90, 120, 150, 180 and 240-minute timepoints) and the overall diagnosis	Up to 7 days per participant
Primary	Percent agreement in diagnosis	Diagnosis compared between the comparative method (ABCA GIRMS) and the candidate method (ABCA2 GIRMS) at each post meal timepoint and the overall diagnosis	Up to 7 days per participant
