cmAngio is intended to process screening mammograms to aid a qualified interpreting physician in the current manual process of identifying Breast Arterial Calcification (BAC).

cmAngio, a proprietary artificial intelligence (AI) based software, is intended to detect, at the study and breast level, the presence or absence of Breast Arterial Calcifications (BAC), an incidental finding in both Full Field Digital Mammogram (FFDM) and Digital Breast Tomosynthesis (DBT) screening mammograms. The device also marks BAC segments on thumbnails of images for localization of BAC.

The software is intended to be used by qualified interpreting physicians in parallel with breast screening mammography workflow. The device is not intended for primary interpretation of digital mammography images as used for breast cancer detection. The device results should not be used alone to make any diagnosis and/or treatment decisions.

The provided FDA 510(k) Clearance Letter for cmAngio® (V1.6) does not contain the detailed information required to answer most of your questions about the acceptance criteria and the study that proves the device meets them. This document is primarily a clearance letter, indicating that the device has been deemed substantially equivalent to a predicate device and outlining regulatory obligations. It does not typically include the specifics of performance studies.

However, based on the information that is available, here's what can be extracted:

Indications for Use:

cmAngio is intended to process screening mammograms to aid a qualified interpreting physician in the current manual process of identifying Breast Arterial Calcification (BAC). It is an AI-based software intended to detect, at the study and breast level, the presence or absence of Breast Arterial Calcifications (BAC) in both Full Field Digital Mammogram (FFDM) and Digital Breast Tomosynthesis (DBT) screening mammograms. The device also marks BAC segments on thumbnails of images for localization. It is to be used by qualified interpreting physicians in parallel with breast screening mammography workflow and is not intended for primary interpretation or for making diagnosis/treatment decisions alone.

Given the typical content of a 510(k) clearance letter versus a full submission, the following information is not present in the provided text:

A table of acceptance criteria and reported device performance.
Sample size used for the test set.
Data provenance for the test set.
Number of experts used to establish ground truth for the test set.
Qualifications of those experts.
Adjudication method for the test set.
Whether a multi-reader, multi-case (MRMC) comparative effectiveness study was done.
The effect size of human readers improving with AI vs. without AI assistance.
Whether a standalone (algorithm-only) performance study was done.
The type of ground truth used (e.g., pathology, outcomes data).
The sample size for the training set.
How the ground truth for the training set was established.

To obtain this information, one would typically need access to the full 510(k) submission document, which includes the detailed clinical and technical performance studies. The clearance letter only summarizes the outcome of the FDA's review.

Dear Rekha Anand:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.
