Ambroxol as a novel disease modifying treatment for Parkinson’s disease dementia: a single-centre, randomized, double-blind, placebo-controlled trial
Why is this study needed?
- Current medications for the treatment of cognitive decline in Parkinson’s disease are helpful, but do not change the course of disease progression.
- Cognitive decline is one of the main contributors to decreased quality of life , as well as increased risk of institutionalization and mortality among individuals with Parkinson’s disease.
- The development of therapies that could delay memory loss in Parkinson’s disease is critical.
What is a clinical trial?
Clinical trial is a scientific investigation of a new therapy, such as new medication. Common questions addressed in clinical trials include:
- Is the medication safe and well- tolerated?
- Is the medication effective?
- What is the best dose?
Participation in clinical trials contributes to the development of new treatments for debilitating medical conditions such as Parkinson’s disease.
What is the Ambroxol Clinical Trial for Parkinson’s disease Dementia (PDD)?
The aim of this trial is to investigate the safety and tolerability of Ambroxol in individuals with PDD.
· Ambroxol is a cough medicine that has been available over the counter in more than 50 countries for over 30 years, but is not available in Canada or the USA.
· Ambroxol has an excellent safety record
· Ambroxol is thought to reduce the levels of a protein in the brain (i.e. alpha-synuclein) that is linked to the progression of Parkinson’s disease
What taking part in the Ambroxol clinical trial involve?
- If you decide to participate in this research, you will be invited for a screening visit, when the research team will assess your eligibility for the study
- If you are eligible for the study, you will be randomized into one of two groups: Ambroxol (1050mg) or placebo.
- The study will last 1 year and involve 11 visits to Parkwood Institute (London, ON)
- In these visits we will collect blood and urine samples to ensure safety. The study doctor will also exam you.
- At the beginning (month 0), middle (month 6), and end (month 12) the research team will assess your memory, thinking, movements, daily functioning and behaviour.
- An MRI will be done at the start and end of the study.
Can I participate in the Ambroxol clinical trial?
You may be eligible for the Ambroxol study if you:
- 50 years old or older
- If your Parkinson’s disease diagnosis preceded changes in memory and thinking by at least 1 year
- If you have a caregiver who sees you at least 4 times a week and is willing to be your study partner
- If you are taking appropriate medication for you Parkinson’s disease symptoms

Getting Older Adults Outdoors (GO-OUT) Study
Are you an older adult who wants to improve your ability to walk outdoors?
What is the GO-OUT study? We are a group of students, physical therapists and researchers from universities in Montreal, Toronto, Winnipeg & Edmonton. We wish to evaluate two programs to help seniors to walk outside more easily.
Who are we looking for? We are looking for adults aged 65 years and older who are interested in walking outside for exercise during the summer.
What will you have to do? You will participate in four evaluations spread out over one year. After the first evaluation, we will use a process that is like flipping a coin to assign you to one of two programs. The programs are:
GO-OUT Workshop & Coaching Program: This program involves a workshop and weekly coaching. Participants will attend an interactive workshop to learn strategies and skills to walk safely outdoors. You will move between stations at which you will practice using a step counter and Nordic walking poles; learn about fall prevention, and footwear, and perform balance exercises. Lunch will be provided. After the workshop, a coach will call you weekly for 10 weeks to coach you to walk outdoors.
GO-OUT Workshop & Outdoor Walking Program: This program involves the same workshop as described above, but you will also participate in an outdoor walking group, led by a physiotherapist, for 10 weeks. In the outdoor walking program, you will meet as a group in a nearby park, twice a week, for 10 weeks.
When and where will the programs run? The GO-OUT workshop will take place in June 2019. The weekly coaching and outdoor walking group will run from June to August, 2019. These dates are tentative. Please see below to get more information for your city.
Is there a cost to participate? No. The GO-OUT programs are FREE of charge as funding is provided through a grant. All participants will receive a free step counter and workshop workbook.

Rhythmic Speech Cueing as a Clinical Tool to Improve Hypokinetic Dysarthria in Individuals with PD
We are looking for people to participate in an experiment that studies how Parkinson’s Disease affects articulatory coordination in speech.
We target two groups of speakers to participate
1) Canadian-English speakers (age 18+) diagnosed with Hypokinetic Dysarthria due to Parkinson’s Disease.
2) Canadian-English speakers (age 18+) without Parkinson’s disease or any other neurogenic disorder
The goal of this study is to answer the question how (speech-) rhythm affects how people with Parkinson’s Disease move and coordinate their articulators, i.e., tongue, lips and jaw, required for linguistically correct productions. In addition, an important part of the proposed study will investigate how synchronizing with an external auditory cue affects speech production of individuals with and without Parkinson’s disease.
If you agree to participate in the study, you will be asked to produce a variety of speech tasks while your speech movements will be recorded using a state-of-the-art computerized movement tracking system (EMA). The session lasts approximately 2 hours in total. If you are interested, please contact us sending a personal message, or by email to set up an appointment.
We are looking forward to hearing from you.

You are invited to participate in a study entitled “Family Perspectives on Assisted Dying.”
Who we are:
We are a team of four researchers from the University of Toronto – two are student occupational therapists and two are professors at the university.
Why we are doing this:
Assisted dying is now an option for individuals eligible in Canada. The change in the law is intended to offer more options, but it may also make some people feel more concerned. There are checks and balances in place to try to prevent any improper use of assisted dying and to promote informed decisions made by the individual who is considering assisted dying.
While some researchers have examined family members’ support of assisted dying, we know very little about the attitudes and perspectives of family members regarding this issue and no research has been conducted to date in Canada. The purpose of this study is to gain further insight into the attitudes, perspectives and experiences of family members now that assisted dying is a legal option.
The findings of this study will contribute to recommendations for supporting both patients and their family members during the dying process.
Who we are asking:
We are asking family members (including close personal friends) who are or who have been involved in the care of individuals with a grievous and irremediable condition to participate in this study. The care recipient must be or have been eligible for health services in Canada. The care recipient does not or did not need to be eligible for assisted dying under the current law in Canada.
What we are asking:
This study asks for your thoughts on the how the legalization of assisted dying affects:
1) Your role in the care of someone who may or may not be considering a legal request for assisted dying;
2) The impact of this role on your health and well-being;
3) Your potential needs for support from the healthcare and social systems.
We will also be asking some general information about you (for example, age and education), but we will not be asking for information that can identify you.
How we’re asking:
We will be asking you to complete a telephone interview for this study by May 2018. We will need to arrange to contact you for the interview, but will delete your contact details once it is complete. We will record the interview anonymously- without any identifying details- so that we can transcribe it. We will ask you at the end of the interview if you still feel or wish your responses to be included – you can then ask to have it deleted if you wish for any reason.
The interview recording will be kept for transcription and then deleted. As we will not have any way to identify each recording, or the transcripts, there will be no way to delete it once it is added to the other responses. Any potentially identifying details will be de-identified or removed.
You also have the option to complete an online survey in place of the telephone interview. We are using a survey system called Survey Monkey. The survey asks for no identifying information from you – only some general demographics. We ask that you take care not to include any identifying details in the open comments sections. If any identifying details are included, we will omit them from any reports/publications/ presentations about this study.
The survey will be open until the end of May 2018. If you wish to withdraw from the survey once you have started it, you can simply click ‘discard’ at any time – this will remove any responses you have entered. Once you click ‘submit’, your responses cannot be removed.
To go to the survey, you can click on the web link below. The first page of the survey will repeat this letter – you can skip it and go to the second page where you will find the consent page.
Please feel free to forward this invitation to any others who are or have been in a position similar to you.
If you have any questions about the survey, please do not hesitate to ask either of the MSc student researchers:
or the professors:
This project has been approved by the University of Toronto Health Sciences Research Ethics Board. If you have any questions about your rights as a participant you may contact them via the Office of Research Ethics: firstname.lastname@example.org or 416-946-3273.

Evaluation of Parkinson’s disease questionnaire used by speech pathologists
The University of Sydney in Australia is conducting an online survey of Registered Occupational Therapists to examine the perceived knowledge, attitudes, behaviours, and barriers of occupational therapists regarding the use of psychological strategies in their practice with clients living with Parkinson’s disease.
This study involves the evaluation of a disease-specific questionnaire that assesses the physical and social effects of PD on speech, swallowing, communication. Determining the appropriateness and accuracy of this questionnaire will help health professionals to better understand the needs of persons with PD in order to provide appropriate care and support.
All potential participants will be invited to go to the questionnaire’s website. Upon opening the website, the participant will be asked to read a Participation Information Statement and to provide consent to proceed with the questionnaire. The questionnaire will take approximately 25 to 30 minutes to complete. The information gathered will be used to evaluate the appropriateness and accuracy of the questionnaire.
If the participant leaves their email address, we will contact them after 2 weeks and will ask them to complete a shorter questionnaire with fewer questions. This will take them approximately 10 minutes to complete.
While the study is primarily being conducted in Australia, the validation of the questionnaire is for a general English-speaking population. The study’s aim is on improving healthcare services and providing better resources for assessing Speech and communication symptom severity in Parkinson’s patients in Australia, but we hope to generalize this improvement for patients across English-speaking countries.

Toronto Western Hospital looking into the build-up of iron in the brains of people with Parkinson’s
Researchers at Toronto Western Hospital are looking for participants for the SKY study (Study of Parkinson’s Early Stage). They are taking a new approach to treating Parkinson’s disease by looking at the build-up of iron in certain regions of the brain among people with Parkinson’s disease. It is not known whether this build-up of iron is causing harm to the brain cells, or whether removing it may improve the motor symptoms of this disease or slow its progress. The SKY clinical study aims to address these questions.

Examining the Prevalence and Associations of Health and Mobility in Canadians
Here is a chance to participate in a study funded by the University of Waterloo International Research and Partnership Grant to examine the effects of health on mobility among Canadians. The aim is to determine how health as well as physical, cognitive and social factors influence injury rates including driving and fall related accidents. Findings from this project will lead to program and service development that address the needs of Canadians as they age. Follow up studies will be done in 5 year intervals to see how health, mobility, driving practices, the environment, activity levels and cognitive function have changed. Comparing data every 5 years will result in greater understanding of health and mobility trends among an aging population. For additional insight findings from this study will be compared to residents of France, who have completed the same survey.
- Over 45 years of age
- Complete a 90 question online survey about your health, attitudes and behaviours, mobility, social demographic factors, driving, falls and a few questions on memory, sleepiness and distraction
