Clinical Study to Predict the Risk of Bone Fractures With the POROUS Ultrasound Device

ClinConnect Summary

This clinical trial is exploring a new ultrasound device called POROUS, which aims to better predict the risk of bone fractures in older adults. Osteoporosis is a common condition that weakens bones, making fractures more likely, but many people who might be at risk are not diagnosed because current methods, like DXA scans, can miss some cases. The POROUS device can provide a clearer, three-dimensional view of bone health without using radiation, and it may help identify issues earlier than traditional methods.

The study is looking for men and women aged 56 to 85 who may have risk factors for developing osteoporosis, such as a family history of fractures or certain medical conditions. Participants will undergo various assessments, including questions about their health, physical tests, and scans with both the POROUS device and DXA at the beginning and end of the study. They will be monitored for three years and contacted every six months to check on their bone health and any new fractures. This research is important as it could lead to better identification of individuals at risk for fractures who could benefit from treatment.

Eligibility criteria

• Inclusion Criteria:
• • Female or male individuals aged 56 to and including 85 years.
• • Written informed consent has been obtained.
• Assessment of risk factors for hip and vertebral fractures:
• • To avoid over- and under-recruiting with regard to the required sample size of participants with ≥ 2-fold increased age-and sex-adjusted risk for hip and vertebral fractures and participants with \< 2-fold increased age- and sex-adjusted risk, clinical risk factors necessary for the calculation of the risk for hip and vertebral fractures (based on the risk calculation scheme outlined in the DVO osteoporosis guideline) are assessed at Screening.

• • Hip fracture during the last year
• • Hip fracture \> 12 months ago
• • Humerus fracture
• • Pelvic fracture
• • Wrist (radius distal) fracture
• General risk factors:
• • Mother or father with hip fracture, if the participant is under 75 years of age

• • Individual is in custody by order of an authority or a court of law.
• • Close affiliation with an investigational site, e.g. employed at investigational site, close relative of an investigator, dependent person (e.g. student of the investigational site).
• Further, individuals who are being or have been treated within the indicated period prior to the beginning of the study with any of the following antiresorptive therapies are excluded from the clinical investigation:
• * Bisphosphonates (due to residual effects of bisphosphonates after discontinuation):
• • Intravenous (IV) zoledronate within the last 3 years.
