Personalizing Osteoporosis Care:
Atypical Femur Fracture (AFF) Clinical and Genetic Risk Factors Study (2018)

Fractures from osteoporosis are more common than heart attack, stroke and breast cancer combined

The current approach to preventing osteoporosis related fractures is to provide very different types of people similar types of bone medications in standard dosage, regardless of sex, age, or race, weight or health status. But not all patients experience the same benefits or side effects from treatment.  We want to understand why and how treatment can be more personalized in the future.

Medical researchers from across Canada are looking for volunteers to help them understand how to personalize osteoporosis care.

 

What is the Personalizing Osteoporosis Care: Atypical Femur Fracture (AFF) Clinical and Genetic Risk Factors Study?
This national study is examining the relationship between the use of bone medications and genetic makeup for the risk of developing an AFF.

Specifically we are looking at whether clinical or genetic factors influence the benefits or risks of bone medications, and possible side effects such as Atypical Femur Fractures (AFFs), a serious type of fracture that is not well understood.

Who should participate in this study?
We encourage you to participate if you are:

  • a woman over 18 years of age
  • have taken bone medications such as
    • Risedronate (Actonel)
    • Alendronate (Fosamax, Fosavance)
    • Etidronate (Didronel, Didrocal)
    • Zolendronate (Aclasta, Reclast)
    • Pamidronate (Aredia)
    • Prolia (denosumab)
  • Have or have not had an atypical femur fracture

What can I expect as a participant?
As a participant in this study, we would ask you to attend one of our collaborating centres in your area for a one-time visit, and provide the following:

  • Answer questions about your medical/family health history,
  • Blood samples for genetic testing, bone health blood tests, and other bone biomarkers,
  • Fingernail samples to examine protein structure,
  • X-rays of your femurs, either to confirm your AFF or to make sure you don’t have one,
  • Bone Mineral Density scan to assess the health of your bones.  

Why should you participate?
Osteoporosis can strike at any age and affect both women and men. 1 on 3 women and 1 in 5 men will suffer from an osteoporotic fracture during their lifetime.

The current approach to preventing osteoporosis fractures is a “one size fits all” approach. Drug therapies given to patients come in one standard dose, regardless of sex, age, race, and drug metabolism.

We aim to change this by understanding how people respond to medications based on medical history and genetics. With the results of this study, we can identify the best treatment with minimal side effects for each person.

Personalizing osteoporosis treatment is the next step in bone health!

Funding for this study is granted by the Canadian Institute for Health Research

Exercise study for men with prostate cancer

This study tests the effectiveness of 2 types of exercise program delivery methods for prostate cancer patients who are taking androgen deprivation therapy (ADT). By doing this research, we hope to better understand the benefits that different programs offer to patients and to find out which program types are most effective and practical. Ultimately, this research will assist in developing and delivering patient programs that focus on managing side-effect of  androgen deprivation therapy. This study is currently recruiting study participants. For more information please visit here

The Ankle Fractures and Bone-Muscle Quality Study

This 250-participant study will examine how various functional, imaging and questionnaire-type tools quantifying leg muscle, bone quality and physical function will help with future ankle fracture risk assessment and prevention.

You can participate if you:

  • Are a woman or man 50 years or older
  • Have never fractured an ankle
  • Do not have any implants at the ankle
  • Have no muscle or Achilles tendon disorders

  1. I am trying to find the research outcomes regarding the use of TNT (Nitro Glycerine) carried out by Toronto University in 2014/15 and undertaken by Dr Jamal. Do you have any pointers on this please at your Osteoporosis clinic? I received an email from their research assistant in Jan 2015 but the findings were never received.

    ‘We looked at 5 different formulations of Nitroglycerin (the ointment used in the previous study, a nitroglycerin patch, a pill-ISMO, and 2 different doses of sublingual tablets – 0.3 and 0.6). We want to see the effect of those formulations on bone formation and resorption, and also see the headaches and patient preference for a certain formulation. The formulation that has the best effect on the bone (and hopefully comes with less headaches and is mostly preferred by the patents) will be used in a larger study to prove that Nitroglycerin in preventing fractures in patients diagnosed with osteoporosis (and hopefully osteopenia). If you are interested, I will send you the results of the study as soon as they become available (end of December 2014 or beginning of January 2015).
