The Exalenz BreathID® Hp Lab System is intended for use to non-invasively measure changes in the 1300/14CO2 ratio of exhaled breath, which may be indicative of increased urease production associated with active Helicobacter pylori (H. pylori) infection in the stomach.
The Exalenz BreathID® Hp Lab System is indicated for use as an aid in the initial diagnosis and post treatment monitoring of H. pylori infection in adult patients and pediatric patients ages 3-17 years old. The Exalenz BreathID® Hp Lab System consists of the appropriate IDkit: Hp™ kit, and the BreathID® Hp device. Auto Sampler and Lab Application.
To be administered by trained personnel as ordered by a licensed healthcare practitioner.
The BreathID® Hp Lab System is a non-invasive breath test system for detecting the presence of Helicobacter pylori (H. pylori). The system consists of an electro-optical medical device with embedded software designed to measure and compute the changes in ratio between 13002 and 1202 concentrations in the patient's exhalation, an Auto Sampler, a Lab Application, and a test kit. The IDkit Hp™ Two kit consists of:
- A 75mg 13C-urea tablet
- A 4.3g package of powdered Citrica (citric acid) ●
- Drinking straw
- Package Insert (Instructions for Use) ●
- Quick User Guide
- 2 Breath Sample Bags (Baseline and Post Ingestion) with bar code labels and a large Sample Transport Bag
Using bags for breath collection along with the Auto Sampler enables off site and deferred testing as well as testing of multiple breath sample bags sequentially in a batch. The BreathID® Hp Lab System measures and compute the ratio between 13CO2 and 12 CQ2 in the patient's exhaled breath before and after the ingestion of 13C-urea. The change in the 13CO2 / 12CO2 ratio before and after ingestion of 13C-urea is used to compute the Delta over Baseline (DOB).
The 13C measurement method for both the subject and the cleared (predicate) versions of the BreathID® Hp Lab systems is based on Molecular Correlation Spectroscopy™ (MCS) technology. MCS technology is based on the concept of optical absorption of specific radiation emitted from CO2 discharge lamps.
This document describes the 510(k) summary for the Exalenz BreathID® Hp Lab System, specifically focusing on expanding its indications for use to include pediatric patients aged 3-17 years old. The device is identical to its predicate, and the submission primarily addresses the expansion of the patient population.
Here's a breakdown of the requested information based on the provided text:
Acceptance Criteria and Device Performance Study
The primary purpose of this 510(k) submission was to expand the indications for use to include pediatric patients. Therefore, the "acceptance criteria" presented below are based on the secondary endpoint of the clinical validation study conducted for this pediatric population expansion, as the device itself is stated to be identical to a previously cleared one for adults. The study aimed to assess performance in pediatrics, supported by existing adult data.
1. Table of Acceptance Criteria and Reported Device Performance
Note: The document only provides performance metrics (Positive Percent Agreement and Negative Percent Agreement) against a stool antigen test for the pediatric study. It does not explicitly state pre-defined "acceptance criteria" numerical thresholds for these performance metrics for the pediatric population within this document. Instead, it states that "These study results met the predefined success criteria for confirming the safety... and for providing further evidence of BreathID Hp Lab System performance..." implying that the reported values were acceptable.
| Performance Metric | Acceptance Criteria (Implicit from Study Success Statement) | Reported Device Performance (Pediatric Population) |
|---|---|---|
| Positive Percent Agreement (PPA) | Evidence of performance to support expanded indication. | 93.3% [95% CI: 68.05%; 99.83%] |
| Negative Percent Agreement (NPA) | Evidence of performance to support expanded indication. | 100% [95% CI: 87.23%; 100%] |
Note on "Cut-off Point": The document mentions a "Cut-off Point" of "5.0 DOB per mil (post dose minus pre dose)" for determining positive/negative H. pylori infection. This is a classification threshold for the device's output, not a performance acceptance criterion in the same vein as PPA/NPA.
2. Sample Sizes and Data Provenance
- Test Set Sample Size:
- Screened: 54 subjects
- Enrolled (Full Analysis - FA set) for Safety Assessment: 53 subjects
- Completed full study protocol with evaluable breath and stool test endpoints: 42 subjects (This is the effective test set size for performance assessment.)
- Data Provenance: The study was prospective and conducted at 6 clinical sites that were geographically diverse (no specific countries mentioned, but given the FDA submission, it's likely U.S. or international sites adhering to relevant regulations).
3. Number of Experts and Qualifications for Ground Truth
The document does not explicitly state how many experts were used or their specific qualifications for establishing the ground truth for the test set. The ground truth was established by a central laboratory analyzing stool specimens with an FDA cleared H. pylori stool antigen test. While this implies expert analysis is involved in running and interpreting such a test, specific details about the individuals (e.g., number, board certification, years of experience) are not provided.
4. Adjudication Method for the Test Set
Not applicable. The ground truth was established using an FDA-cleared stool antigen test at a central laboratory, which is a definitive clinical test, not based on expert consensus requiring adjudication.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No, an MRMC comparative effectiveness study was not conducted. This device is a diagnostic test (breath test) with a determined cut-off for positive/negative results, not an imaging analysis system typically evaluated with MRMC studies for human reader improvement with AI assistance. The study compared the device's results to a established clinical ground truth (stool antigen test).
6. Standalone Performance Study (Algorithm Only)
Yes, the performance metrics (Positive Percent Agreement and Negative Percent Agreement) are presented as standalone performance of the BreathID® Hp Lab System, classifying patients as positive or negative based on its 5 DOB cut-off, compared to the stool antigen test. There is no human-in-the-loop component mentioned in its operation or the reported performance.
7. Type of Ground Truth Used
The type of ground truth used was an FDA cleared H. pylori stool antigen test, analyzed by a central laboratory. This is a laboratory/clinical test result considered a definitive diagnostic marker for H. pylori infection.
8. Sample Size for the Training Set
The document does not specify a sample size for a training set. The purpose of this 510(k) was to expand the indication for an already cleared and identical device. The "clinical validation" described is essentially a performance evaluation in the new (pediatric) population, not a de novo algorithm development or training. The device's underlying technology and cutoff (5.0 DOB) were already established and validated in adult populations (as per the predicate device K162150).
9. How Ground Truth for the Training Set Was Established
As there is no clear mention of a "training set" in the context of this 510(k) submission, the establishment of ground truth for a training set is not applicable here. The device's core functionality and diagnostic characteristics were presumably established during the development and clearance of the predicate device (K162150) for adults.

{6}------------------------------------------------
Comparison of Intended Use:
The intended use of the BreathID® Hp Lab System is substantially equivalent to its predicate; both are intended for the initial diagnosis and post treatment monitoring of H. pylori infection in patients, and both are prescription devices. The BreathID® Hp Lab System which is the subject device is indicted for use on both adult and pediatric patients
{7}------------------------------------------------
ages 3-17 years old, while the predicate device is only indicated for adult patients. In addition, the subject device has minor software and hardware changes which have no effect on the fundamental intended use or indications for use of the system nor do they alter the system diagnostic characteristics or raise any new safety issues.
Ingested Drug:
The ingested drug product used in the BreathID® Hp Lab System IDkit Hp™ Two kit, (13C-Urea tablet, 75mg and Citrica powder, 4g), was originally approved in NDA 21-314. The identical drug product with identical preparation and administration is used in the cleared predicate device BreathID® Hp Lab System kit.
Comparison of Technological Characteristics:
The BreathID® Hp Lab System shares with its predicate device the same technology. the same test substrate, and the same diagnostic capabilities. Both the subject and predicate systems, use the MCS technology (Molecular Correlation Spectroscopy) and measure the ratio of 13CO2/12CO2 in exhaled breath prior to and after administration of the test substrate (13C-Urea). The MCS technology measures the light absorbance by an infrared spectrometry, which is correlative to CO2 concentration in the breath sample. The output result in both systems is the Delta Over Baseline (DOB) and a positive/negative determination is based on the same assay cut-off (≥5 DOB).
Like its predicate device, the BreathID® Hp Lab System includes an analyzer device with embedded SW and a test kit. In addition, the subject system and predicate system also includes the Auto Sampler with its embedded SW and the BreathID® Lab Application with its Work Station. These components directly relate to the use of breath bags in the subject system, are designed for the convenience of the operator and are used in the FDA cleared predicate device (K162150). As with the predicate device, the subject system uses breath bags, where the breath is exhaled through the mouth into the bag.
Summary of Performance Testing:
Exalenz has performed extensive and well-executed verification and validation to verify the performance of the BreathID® Hp Lab System.
- Software Verification and Validation
Software testing was conducted to evaluate the performance of the subject system and to verify that it performs according to its specifications. Verifications involved functionality testing, timing analysis, integration with the hardware, and error detection and handling. Verification was achieved by design reviews, code walkthroughs, functional testing of sub-components and integration testing with the hardware. Additionally, the software was extensively verified at the system level.
{8}------------------------------------------------
Clinical Validation ●
A multi-center, non-randomized, open label study was conducted with the primary goal of confirming the safety of the 13C-urea substrate in pediatric subjects, and a secondary goal of assessing performance of the BreathID® Hp Lab System using breath sample bags in this population, compared to stool antigen testing. Supported by existing clinical performance in the adult population, device performance was assessed in a limited clinical study in a pediatric population as described below. The study was not powered to assess efficacy. A central laboratory analyzed the stool specimens with an FDA cleared H. pylori stool antigen test. The study was conducted at 6 clinical sites that were geographically diverse, differing in size (from small private clinics to large hospitals), diverse in experience representing both point of care testing as well as sites utilizing a clinical laboratory. Local site personnel were trained on administering the breath test. To represent point of care and clinical laboratory settings, the bagged sample analysis was performed either on site or at a central laboratory using a BreathID® Hp Lab System.
The primary study endpoint was to confirm the safety of the 13C-urea substrate using the standard dose of 75mg 13C-urea and 4g citric acid in the pediatric population. The safety endpoint included all adverse events (AEs).
The secondary endpoint was performance, assessed as the positive percent agreement and negative percent agreement between the BreathID® Hp | Lab System, applying the predefined threshold of 5 DOB, and the stool antigen test results.
Main Results
A total number of 54 subjects were screened. of which 1 subject was a screening failure prior to any study related procedure. Fifty-three subjects were enrolled (full analysis - FA set) and were followed for the safety assessment. Forty-two of them completed the full study protocol requirements for the FA set with evaluable breath and stool test endpoints.
Among the 53 pediatric subjects followed for the safety assessment, one adverse event of vomiting was experienced by one subject (1.89%) and resolved on the same day. There were no reportable major safety concerns due to adverse events.
The positive percent agreement between the breath test and the stool antigen test results was 93.3% [95% C1:68.05:99.83] and the negative percent agreement was 100% [95% CI: 87.23%;100%].
These study results met the predefined success criteria for confirming the safety of the 13C-urea substrate in the pediatric population, and for providing further evidence of BreathID Hp Lab System performance in this population taking into consideration prior supportive clinical performance in the adult population.
{9}------------------------------------------------
Conclusion:
The information submitted in this premarket notification is complete and demonstrates that the BreathID® Hp Lab System is as safe and effective as the predicate device and supports a substantial equivalence decision.
