Intended Use
Opulus™ Lymphoma Precision is a software device that uses a machine learning-based algorithm to automate segmentation and visualization of lesions along with automation of measurement of total metabolic tumor volume within whole-body FDG-PET/CT scans of patients with FDG-avid lymphomas. Opulus™ Lymphoma Precision is used to assist trained interpreting physicians with visualization of suspected lesions and calculation of total volume of all lesions in a body. This information can be used in addition to the standard of care image interpretation of FDG-PET/CT scans. Opulus™ Lymphoma Precision annotated images can be reviewed by an appropriately trained physician. The algorithm is assistive, and requires a radiologist review, who will make the final decision on FDG-PET/CT image interpretation.

Description of the training set, sample size, data source, and annotation protocol

The performance validation dataset was fully independent from the training and characterization datasets: FDG-PET/CT scans came from an independent set of patients and the manual reads were performed by an independent pool of radiologists. Further, the performance validation dataset was not available to the algorithm developers during the algorithm training.

Description of the test set, sample size, data source, and annotation protocol

The performance validation study of the Opulus™ Lymphoma Precision algorithm included 182 unique patients' FDG-PET/CT scans with various gender, ethnicity and age that were representative of the Intended Use and population for the algorithm. The respective FDG-PET/CT scans were obtained from multiple geographical locations across the U.S., Canada, Europe, Australia, and Taiwan, using scanners from different manufacturers and models including GE, Siemens, Philips.

Reference standard (ground truth) was established using three radiologists/nuclear medicine physicians with expertise in interpreting PET/CT scans from patients with FDG-avid lymphoma. The ground truth for each scan was based on the independent input from three radiologists randomly selected from a pool of nine radiologists.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The performance validation study was conducted using 182 unique patients' FDG-PET/CT scans. The objectives were to demonstrate agreement of TMTV quantitative estimates between aTMTV and manual (mTMTV) and accuracy in lesion segmentation by comparing aTMTV-generated contours and ground truth. The dataset was evaluated using metrics of absolute agreement between the Opulus™ Lymphoma Precision algorithm output and the ground truth TMTV under cubic root, as well as with the Dice Similarity Coefficient (DSC).

Key results: The mean difference between Opulus™ Lymphoma Precision algorithm and the ground truth was -0.20 cm (95% CI, cm: -0.50, 0.10) for TMTV values

Dear Aarti Shukla:

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.

1. DEVICE DESCRIPTION

Opulus™ Lymphoma Precision is an assistive tool which can be used by physicians to automate the labor intensive task of quantifying disease burden in whole-body FDG-PET/CT scans of patients already diagnosed with FDG-avid lymphomas. It does so by using a machine learning methodology to localize and segment FDG-PET activity ('hot-spots' on FDG-PET scans) of lymphoma lesions within a PET/CT image. Opulus™ Lymphoma Precision does not screen for or diagnose lymphoma. It is intended for patients already diagnosed with FDG-avid lymphoma.

The following is a list of key functionalities algorithm performs to accomplish the proposed intended use.

  • localization and segmentation,
  • visualization of lymphoma-related tumor lesions
  • quantification of Total Metabolic Tumor Volume (TMTV)

Opulus™ Lymphoma Precision aids the efficiency of medical professionals by automatically generating tumor boundary Regions of Interest (ROIs) and quantifying TMTV, which is a tedious task when performed manually. The physician has the option to accept/reject the output generated by the device. The user does not have the ability to modify the device output.

4. PERFORMANCE EVALUATION

Safety and performance of Opulus™ Lymphoma Precision have been evaluated and verified in accordance with software specifications and applicable performance standards through software verification and validation testing. The software verification and validation activities were performed in accordance with IEC 62304:2006/AC:2015 - Medical device software – Software life cycle processes, in addition to the FDA Guidance document, "Content of Premarket Submissions for Device Software Functions" June 14, 2023.

The performance validation study of the Opulus™ Lymphoma Precision algorithm included 182 unique patients' FDG-PET/CT scans with various gender, ethnicity and age that were representative of the Intended Use and population for the algorithm. The respective FDG-PET/CT scans were obtained from multiple geographical locations across the U.S., Canada, Europe, Australia, and Taiwan, using scanners from different manufacturers and models including GE, Siemens, Philips.

Reference standard (ground truth) was established using three radiologists/nuclear medicine physicians with expertise in interpreting PET/CT scans from patients with FDG-avid lymphoma. The ground truth for each scan was based on the independent input from three radiologists randomly selected from a pool of nine radiologists.

The objectives of the performance validation study were to demonstrate agreement of TMTV quantitative estimates between aTMTV and manual (mTMTV), confirming that there is an acceptable difference between aTMTV and mTMTV and accuracy in lesion segmentation by comparing aTMTV-generated contours and ground truth. The dataset was evaluated using metrics of absolute agreement between the Opulus™ Lymphoma Precision algorithm output and the ground truth TMTV under cubic root, as well as with the Dice Similarity Coefficient (DSC).
