Trial summary

Atypical femur (thigh bone) fractures (AFFs) are uncommon low-trauma fractures which often occur without warning, are highly debilitating, and are slow to heal. As physicians learn more about them, AFFs are increasingly being identified prior to a total break. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 30 to 100 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Female or male; ii. Over the age of 30; iii. Experienced an incomplete AFF that satisfies the diagnostic criteria as set forth by the American Society for Bone and Mineral Research (ASBMR) International Task Force on AFFs:
  • Atraumatic or low trauma incomplete stress fractures, defined as fractures sustained with minimal force, such as a fall from standing height;
  • From distal to the lesser trochanter to proximal to the supracondylar flare along the femoral shaft.
  • Radiographic confirmation of AFF features is required for a definitive diagnosis. Incomplete AFF features include cortical thickening, cortical beaking, and lucency line. Patients with cortical beaking without lucency line can be included.

Who cannot join

  • Peri-prosthetic fractures, ii. High trauma fractures, iii. Pathological fractures secondary to metastases or metabolic bone diseases other than osteoporosis, iv. Fractures that are not confirmed by radiological investigations, v. Contraindication to use of teriparatide such as:
  • pregnant or nursing mothers, or women who are planning on pregnancy within 1 year of completing teriparatide therapy,
  • hypersensitivity to teriparatide,
  • severe renal impairment,
  • multiple myeloma,
  • active cancer in past 5 years (other than non-melanoma skin cancer),
Show all 11Show fewer
  • primary hyperparathyroidism,
  • hypercalcemia,
  • Paget's disease or other conditions that may increase the risk for osteosarcoma,
  • Prior radiation therapy involving the skeleton, vi. Concomitant use of other osteoporosis therapies including bisphosphonates or denosumab (except calcitonin).
  • AFF patients with complete fractures on the contralateral side or patients with secondary osteoporosis will not be excluded.

About this study

Official title: Effect of Teriparatide on Fracture Healing in Patients With Incomplete Atypical Femur Fractures: a Randomized Controlled Trial

Atypical femur (thigh bone) fractures (AFFs) are uncommon low-trauma fractures which often occur without warning, are highly debilitating, and are slow to heal. As physicians learn more about them, AFFs are increasingly being identified prior to a total break. However, there's no evidence on the best way to treat these non-displaced AFFs. One option is teriparatide, an osteoporosis medication that can build new bone. Investigators will conduct a double blind randomized placebo controlled trial to examine whether teriparatide use in AFF patients with an incomplete break will help accelerate fracture healing and prevent surgical intervention. Co-primary outcomes include change in WOMAC scores from baseline to 12 months and number of participants requiring surgical intervention at 12 months. Investigators will recruit 60 women and men over the age of 30 who have experienced an incomplete AFF. Participants will be randomly assigned to either teriparatide (20 mcg/day) or placebo (using an identical injection pen) for up to 2 years. As AFFs are highly debilitating, a trial examining the use of Teriparatide in this population is urgently needed.

What is being measured

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

  1. Change in the modified The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)of the affected limb (the femur that has the incomplete AFF)

    Measured: baseline to 12 months

  2. The proportion of patients requiring surgical intervention

    Measured: baseline to 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Teriparatide 20 mcg in people with Non Displaced Atypical Femoral Fractures, run by University Health Network, Toronto at 1 site in Canada.

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 4 inclusion and 11 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 1 Jun 2023. 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 Canada. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Change in the modified The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)of the affected limb (the femur that has the incomplete AFF) (time frame: baseline to 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 1 Jun 2023.
