Trial summary

The purpose of this protocol is to determine the risk of atypical femoral shaft (thigh bone) fractures after long term fracture prevention therapy with a class of drugs called "bisphosphonates", colloquially referred to as Alendronate, risedronate, Ibandronate, and Zoledronate.

About this study

The purpose of this protocol is to determine the risk of atypical femoral shaft (thigh bone) fractures after long term fracture prevention therapy with a class of drugs called "bisphosphonates", colloquially referred to as Alendronate, risedronate, Ibandronate, and Zoledronate.

In addition, the study is designed to find out which patient is most likely to develop this potential life changing complication and why. Finally, the results of this study will help clinicians to better understand the reason and thus tailor patient specific treatments…i.e., "the right treatment for the right patient for right duration."

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Prodromal bone deterioration (PBD)

    Determine the prevalence of PBD and/or Atypical Femoral Fractures (AFF) in patients with post-menopausal or glucocorticoid related osteoporosis, either treated with bisphosphonate (BP) for more than 2 years or never treated with a BP

    Measured: 5 years

Secondary outcomes (1)
  1. Diagnosis of PBD

    Refine diagnostic criteria for the diagnosis of PBD

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

An observational study of Osteoporosis and Atypical Femoral Fractures, run by Henry Ford Health System at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Prodromal bone deterioration (PBD) (time frame: 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02155595, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Mar 2019.
