Official Title: TOPAZ Study, Trial of Parkinson's and Zoledronic Acid A Randomized Placebo-controlled Trial of Zoledronic Acid for Prevention of Fractures in Patients with Parkinson s Disease

A Study On:

Brain - Neurologic/ Psychologic

Parkinson Disease

Study Description

This home-based randomized clinical trial is designed to test the efficacy of ZA-5 mg in Parkinson's disease (PD) and parkinsonism patients. This trial will also address barriers to treatment of patients with PD and parkinsonism by providing rigorous evidence about whether ZA reduces fracture risk in patients with PD and parkinsonism, simplifying treatment by giving ZA at home without extra medical visits and BMD testing, and overcoming poor persistence with oral therapies because one infusion may prevent bone loss for at least 2 years. The outcome of this trial will demonstrate how a home-based fracture prevention can reach older PD patients who would not otherwise receive treatment to reduce their high risk of fractures.

Patients with PD will be recruited throughout the US by participating neurologists and health networks as well as the Parkinson's Foundation. Patients may also self-refer to the study. Interested patients can access study information on a study website (topaz.eurekaplatform.org) as well as through the Parkinson's Foundation Helpline. Patients who wish to enroll will be directed to an interactive electronic consent (eConsent). Following eConsent, participants complete a screening questionnaire (to confirm eligibility), followed by a baseline questionnaire. If a participant is determined to be eligible following these steps, they may be scheduled for a Telemedicine assessment to further confirm the PD or parkinsonism diagnosis, unless they have been referred directly from a participating neurologist. If confirmed, the participant will be mailed a supply of vitamin D3 800-1000 IU and instructed to take one vitamin D tablet every day for 2 months. Lastly, a Nurse Home Visit will be scheduled and conducted to confirm final eligibility, randomization, and administration of the study drug, if appropriate. Participants who are randomized will be contacted every 4 months for at least 2 years to determine if they have had any fractures.

Eligibility

Current Parkinson's Disease diagnosis or neurodegenerative parkinsonism diagnosis (including progressive supranuclear palsy, multiple system atrophy, cortical basal degeneration, vascular parkinsonism, dementia with Lewy bodies or another form of neurodegenerative parkinsonism) based on an expert assessment (neurologist diagnosis via medical records confirmation or Telemedicine Screening Assessment)

Willing and able to provide informed consent

History of hip fracture
Any use of a bisphosphonate drug within the last 12 months
Use of any other osteoporosis treatment (such as SERMs and denosumab) within the last 6 months
Tooth extraction or invasive dental procedures within the past 30 days or planned/scheduled extraction/procedure in the next 12 months

Non-ambulatory, i.e., unable to walk without assistance of another person.

Undergoing kidney dialysis
A diagnosis of multiple myeloma or Paget's disease
Unable to speak or read English sufficiently to complete informed consent
Any other criteria, which would make the patient unsuitable to participate in this study as determined by the study staff (e.g., an uncontrolled drug and/or alcohol addiction)

A female nurse attentively holds a tablet, ready to assist with patient care and medical information.

In the instance of parental permission, “You” refers to “Your child.”

Please read the information below and ask questions about anything that you do not understand. A
researcher listed above will be available to answer your questions.

You are being asked to participate in a clinical research potential participant database to identify
potential clinical research studies you may be eligible for. Participation in this database is voluntary.
You may choose to skip any question. You may refuse to participate or discontinue your involvement
at any time without penalty or loss of benefits. You are free to withdraw from this database at any
time. If you decide to withdraw from this database you should notify the research team
immediately.

You are eligible to participate in this study if you may be interested in participating in a research trial at UCI Health

We would like to interview you to learn more about your eligibility for current clinical research studies at UCI. The interview will last about 5-30 minutes, depending on the extent of your medical history.

Possible risks/discomforts associated with the database are hearing about potential clinical research studies that may not be of interest to you, invasion of your privacy, or a potential breach of confidentiality.

There are no direct benefits from participation in the database. However, this database may help inform you on clinical research studies that you may be eligible for. Participation in UCI clinical research studies help us gain important data and knowledge that may lead to improved treatment options for people with similar conditions to you in the future.

There are no alternative procedures available. The only alternative is not to participate in this study.

There is no compensation for your participation in this database.

There is no cost to you for participation in this database.

All information collected will be stored confidentially in a world-class securely-hosted application, “RealTime CTMS,” with robust data protections and encryption. This application has HIPAA compliant architecture and application rules to ensure data privacy and regulatory compliance.

Researchers will use your information to assess your eligibility for current and future clinical research studies at UCI. You may opt out at any time.

The research team, authorized UCI personnel, and regulatory entities, may have access to your study records to protect your safety and welfare.

While the research team will make every effort to keep your personal information confidential, it is possible that an unauthorized person might see it. We cannot guarantee total privacy.

Future Research Use
Researchers will use your information to conduct this study. Once the study is done using your information, we may share them with other researchers so they can use them for other studies in the future. We will not share your name or any other private identifiable information that would let the researchers know who you are. We will not ask you for additional permission to share this de-identified information

Data Retention - In accordance with UC Office of the President policy, information will be retained for 10 years after the end of the calendar year in which the research is completed.

If, during the course of this study, significant new information becomes available that may relate to your willingness to continue to participate, this information will be provided to you by the research team listed at the top of the form.

If you have any comments, concerns, or questions regarding the conduct of this research please contact the researchers listed at the top of this form
