TOPAZ Trial

Join a Parkinson’s Study Without Ever Leaving Your Home

Did you know that people with Parkinson's disease (PD) have a higher risk of fractures?

Help us find a solution.
The TOPAZ study will test if a medicine called zoledronate can prevent fractures in people with PD. A team of doctors who are experts in bone health and PD are leading the study. The use of zoledronate in this study is investigational.

You can join if:

  • You have Parkinson's disease or Parkinsonism
  • Are 60 year old or older

The study is done from your home!

  • If you are eligible for the study, a nurse will come to your home to give you a short exam.
  • You'll receive a one-time dose of the study treatment (either zoledronate or a placebo)
  • During the study, we will contact you every four months to check if you have had any new fractures

Earn $100 upon enrollment and $50 per year during the study.

This study is endorsed by the Parkinson's Foundation and the Parkinson's Study Group.
