CT-Based Modeling of Bone Micro-Architecture and Fracture-Risk in COPD
United States560 participantsStarted 2019-02-26
Plain-language summary
The goal of this translational study is to establish a newly emerging CT-based tool for the characterization of changes in bone micro-architecture and assessment of their implications for fracture-risk in a population of COPD patients at risk for osteoporosis. The tool will be suitable and generalizable across emerging CT scanners from different vendors, and it will provide a more structurally-based assessment of osteoporosis and bone loss than is provided by simple bone density measures. The study will characterize the impact of different COPD-related factors on bone structure, and their implications for fracture-risk, leading to the development of a COPD-specific model for assessment of fracture-risk that will utilize patient-specific demographic, clinical and radiographic data, and CT BMD at the spine, as well as bone structural measures at the hip and/or ankle.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Current or former smoker, defined as having at least 10-pack year lifetime history
* Age: 45-90
Subjects will be stratified into groups based on COPD disease status: smokers with COPD and smokers without COPD.
Smokers with COPD will be further stratified into three groups: low emphysema (\< 3%), moderate emphysema (between 3 and 10%), and severe emphysema (\> 10%).
Exclusion Criteria:
* Pregnant or breast-feeding
* Metastatic Malignancy
* Currently receiving dialysis
* Any lower extremity fracture within the last year
* Any lower extremity fracture with hardware implant(s)
* History of bilateral tibia fractures
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
