Yes
The device description explicitly states that Cleerly LABS "utilizes machine learning and simple rule-based mathematical calculation components" and "applies deep learning methodology to identify high quality images, segment and label coronary arteries, and segment lumen and vessel walls."
No
Explanation: The device is described as a post-processing tool for viewing and analyzing cardiac CT data to aid in determining treatment paths, not for directly treating or preventing a disease or condition. It assists in diagnosis and assessment, but does not provide therapy.
Yes
Explanation: The "Intended Use / Indications for Use" section states that the software is used for "determining the presence and extent of coronary plaques (i.e. atherosclerosis) and stenosis in patients who underwent Coronary Computed Tomography (CCTA) for evaluation of CAD or suspected CAD." This activity, which involves analyzing medical data to identify disease, is a diagnostic function.
Yes
The device is described as a "web-based software application" and a "post-processing web-based software application" that analyzes existing CT data. There is no mention of accompanying hardware or hardware components being part of the device itself.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the human body. The description clearly states that Cleerly LABS analyzes cardiac computed tomography (CT) data, which are images generated by a medical imaging scanner, not biological samples like blood, urine, or tissue.
- The intended use is for viewing and analyzing imaging data. The software processes existing CT images to help medical professionals assess coronary arteries. This is a post-processing tool for medical imaging, not a test performed on a biological specimen.
While the software uses machine learning and provides measurements and reports, its core function is the analysis and visualization of medical images, which falls outside the definition of an In Vitro Diagnostic device.
No
The input document explicitly states "Control Plan Authorized (PCCP) and relevant text: Not Found," indicating no mention of PCCP approval or clearance.
Intended Use / Indications for Use
Cleerly LABS is a web-based software application that is intended to be used by trained medical professionals as an interactive tool for viewing and analyzing cardiac computed tomography (CT) data for determining the presence and extent of coronary plaques (i.e. atherosclerosis) and stenosis in patients who underwent Coronary Computed Tomography (CCTA) for evaluation of CAD or suspected CAD. This software post processes CT images obtained using any Computed Tomography (CT) scanner. The software provides tools for the measurement and visualization of coronary arteries.
The software is not intended to replace the skill and judgment of a qualified medical practitioner and should only be used by people who have been appropriately trained in the software's functions, capabilities and limitations. Users should be aware that certain views make use of interpolated data. This is data that is created by the software based on the original data set. Interpolated data may give the appearance of healthy tissue in situations where pathology that is near or smaller than the scanning resolution may be present.

Device Description
Cleerly LABS is a post-processing web-based software application that enables trained medical professionals to analyze 2D/3D coronary images acquired from Coronary Computed Tomography Angiography (CCTA) scans. The software is a post-processing tool that aids in determining treatment paths for patients suspected of having coronary artery disease (CAD).
Cleerly LABS utilizes machine learning and simple rule-based mathematical calculation components which are performed on the backend of the software. The software applies deep learning methodology to identify high quality images, segment and label coronary arteries, and segment lumen and vessel walls. 2D and 3D images are presented to the user for review and manual editing. This segmentation is designed to improve efficiency for the user, and help shorten tedious, timeconsuming manual tasks.
The user is then able to edit the suggested segmentation as well as adjust plaque thresholds, demarcate stenosis, stents, and chronic total occlusions (CTOs) as well as select dominance and indicate coronary anomalies. Plaque, stenosis, and vessel measurements are output based on the combination of user-editable segmentation and user-placed stenosis, stent, and CTO markers. These outputs are mathematical calculations and are not machine-learning based.
Cleerly LABS provides a visualization of the Cleerly LABS analysis in the CORONARY Report. The CORONARY Report uses data previously acquired from the Cleerly LABS image analysis to generate a visually interactive and comprehensive report that details the atherosclerosis and stenosis findings of the patient. This report is not intended to be the final report (i.e., physician report) used in patient diagnosis and treatment. Cleerly Labs provides the ability to send the text report page of the CORONARY Report to the user's PACS system.
Cleerly LABS software does not perform any functions that could not be accomplished by a trained user with manual tracing methods or other commercially available software. Rather, it represents a more robust semiautomatic software intended to enhance the performance of time-intensive, potentially error-prone, manual tasks, thereby improving efficiency for medical professionals in the assessment of coronary artery disease (CAD).

6. Substantial Equivalence
The subject version of Cleerly LABS has an identical intended use and similar operating principles and technological characteristics as the previously cleared predicate Cleerly LABS v2.0 (K202280) device. The subject device introduces modifications to the product labeling as well as changes to the device's operating principle (i.e., workflow) and minor incremental technological enhancements/changes. The modifications do not introduce any changes to the previously cleared existing algorithms or simple mathematical calculations (Cleerly LABS v2.0 (K202280)) and, consequently, could not significantly affect safety or effectiveness. Software testing demonstrates that the subject device Cleerly LABS continues to be safe and effective for its intended use and substantially equivalent to the predicate device Cleerly LABS v2.0.
In addition, the core functions of Cleerly LABS are supported by artificial intelligence, nonadaptive machine learning algorithms for CCTA processing and analysis. As a result, an administrative change to the product code has been introduced for the subject device.

9. Conclusions
The subject version of Cleerly LABS has the same intended use, indications for use, software algorithm and fundamental technology design as the predicate Cleerly LABS v2.0 (K202280). The modifications to the product labeling as well as changes to the device's operating principle (i.e., workflow) and minor incremental technological enhancements/changes do not raise different questions of safety or efficacy. No changes have been made to machine learning algorithms or simple mathematical equations. Software testing demonstrates that the subject device Cleerly LABS continues to perform as intended; therefore, the subject version of Cleerly LABS is as safe and effective as the predicate Cleerly LABS v2.0 (K202280). Thus, Cleerly Labs v2.0 is substantially equivalent.
