TBS iNsight is a software provided for use as a complement to both DXA analysis and clinical examination. It computes the antero-posterior spine DXA examination file and calculates a score (Trabecular Bone Score - TBS) that is compared to those of the age-matched controls. The TBS is derived from the texture of the DXA image and has been shown to be related to bone microarchitecture. TBS iNsight provides as an option an assessment of 10-year fracture risk. It provides an estimate of 10-year probability of hip fracture and 10-year probability of a major osteoporotic fracture (clinical spine, forearm, hip or shoulder fracture). This estimate is based on the WHO's FRAX® Fracture Risk Assessment Tool, after adjustment for the TBS. The tool has been validated for Caucasian and Asian men and post-menopausal women between 40 and 90 years old. TBS provides information independent of BMD value: it is used as a complement to the data obtained from the DXA analysis and the clinical examination (questioning by the clinician about patient history, bioassay of bone resorption markers . . . ). The results can be used by a physician in conjunction with other clinical risk factors as an aid in the diagnosis of osteoporosis and other medical conditions leading to altered trabecular bone microarchitecture, and ultimately in the assessment of fracture risk. The TBS score can assist the health care professional in monitoring the effect of treatments on patients across time. Overall fracture risk will depend on many additional factors that should be considered before making diagnostic or therapeutic recommendations. The software does not disease, or recommend treatment regimens. Only the health care professional can make these judgments.

No
The description focuses on calculating a score based on image texture and integrating it with a known risk assessment tool (FRAX). There is no mention of AI/ML techniques like training, testing, or specific algorithms typically associated with these technologies. The performance studies describe clinical validation against existing data and cohorts, not the performance of an AI/ML model.

No
The software aids in diagnosis and risk assessment, and helps monitor treatment effects, but it explicitly states that it does not treat disease or recommend treatment regimens.

Yes

The intended use explicitly states that the results "can be used by a physician in conjunction with other clinical risk factors as an aid in the diagnosis of osteoporosis and other medical conditions leading to altered trabecular bone microarchitecture, and ultimately in the assessment of fracture risk."

Yes

The device is explicitly described as "software provided for use as a complement to both DXA analysis and clinical examination." It processes existing DXA image files and clinical data to calculate scores and fracture risk, without including any hardware components.

Based on the provided information, this device is NOT an IVD (In Vitro Diagnostic).

Here's why:

  • IVD definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • TBS iNsight's function: TBS iNsight analyzes images (DXA scans) of the spine. It does not analyze biological samples taken from the patient.
  • Intended Use: The intended use describes the software as a complement to DXA analysis and clinical examination, aiding in the diagnosis of osteoporosis and assessment of fracture risk based on image texture and clinical factors. This is distinct from analyzing biological markers in a sample.

Therefore, while TBS iNsight is a medical device used in diagnosis and risk assessment, it falls under the category of image analysis software rather than an in vitro diagnostic device.

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

The performance of TBS iNsight was evaluated via clinical studies covering the following:

  • Clinical Aspects FRAX adjusted for TBS: TBS is an independent clinical risk factor for fracture and can be used in association with WHO's FRAX® to adjust and improve the FRAX® probability of hip fracture and of major osteoporotic fracture in postmenopausal women and in men. This was demonstrated using 3 published studies and a report provided by the Frax group to Medimaps.
  • Clinical Aspects TBS iNstats: TBS iNsight provides a breakdown of the patients DXA exams based on their BMD and TBS values. The fracture risk in each cell has been evaluated based on a cohort of 29,000 Canadian women. Two studies have been used to demonstrate that the TBS categories of fracture risk computed from the Canadian study are applicable to the US population and another study to demonstrate that the TBS values of the population included in the Canadian study are similar to the normal TBS values of the US population.
  • Normative data: A US clinical study including Non-Hispanic white US women and men. Non-Hispanic black US women and men and Mexican women and men, aged 20 to 85 years has been conducted. The data provided from the Nhanes IV database, which is the reference database for the US. TBS values obtained for all lumbar vertebral combinations (L1, L2, L3, L4) decreased significantly with age. These decreases seen in lumbar spine TBS reflect the age-related microarchitecture changes at spine.

CONFORMITY TO RECOGNISED STANDARDS

TBS iNsight has been developed in accordance with the following product standards & FDA Guidance :

    1. IEC 62304:2006, Medical Device Software: Software Life Cycle Processes
  • II. ISO 14971:2007, Medical Devices: Application of Risk Management to Medical Devices
  • III. General Principles of Software Validation: Final Guidance for Industry and FDA Staff (2002)

  • V. Guidance for Industry - Cybersecurity for Networked Medical Devices Containing Off-the Shelf (OTS) Software (2005)

PERFORMANCE BENCH TESTING

No new bench testing since K121716.

CLINICAL TESTING

The performance of TBS iNsight was evaluated via clinical studies covering the following :

  • Clinical Aspects FRAX adjusted for TBS ● TBS is an independent clinical risk factor for fracture and can be used in association with WHO's FRAX® to adjust and improve the FRAX® probability of hip fracture and of major osteoporotic fracture in postmenopausal women and in men. This was demonstrated using 3 published studies and a report provided by the Frax group to Medimaps.
  • Clinical Aspects TBS iNstats ●

TBS iNsight provides a breakdown of the patients DXA exams based on their BMD and TBS values. The fracture risk is each cell has been evaluated based on a cohort of 29,000 Canadian women. Two studies have been used to demonstrate that the TBS categories of fracture risk computed from the Canadian study are applicable to the US population and another study to demonstrate that the TBS values of the population included in the Canadian study are similar to the normal TBS values of the US population.

  • Normative data ●
    A US clinical study including Non-Hispanic white US women and men. Non-Hispanic black US women and men and Mexican women and men, aged 20 to 85 years has been conducted. The data provided from the Nhanes IV database, which is the reference database for the US. TBS values obtained for all lumbar vertebral combinations (L1, L2, L3, L4) decreased significantly with age. These decreases seen in lumbar spine TBS reflect the age-related microarchitecture changes at spine.

Based on this clinical studies, no new questions arise regarding the safety and effectiveness of this device, which can be considered substantially equivalent to the predicate devices.

CONCLUSION

Medimaps group has demonstrated through the testings that the safety and effectiveness of TBS iNsight is not compromised and that they met all acceptance criteria, demonstrating that it can be considered substantially equivalent to the predicate devices.
