Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study will be conducted online. Participants will be randomly allocated to one of two intervention groups (Arm 1, 2) or one control group (Arm 3: discussed in the next section). First, participants in Arms 1 and 2 will be asked to provide some background information (e.g., age, gender, stroke type/year) and details of their current physical, cognitive and emotional functioning. Immediately after this, participants will be asked to complete a brief survey (6 questions) about experimental stem cell treatments (e.g. perceived risks, benefits, accessibility, affordability).
Arm 1:
Participants in Arm 1 will then be directed via a web link to an information booklet produced by the International Society for Stem Cell Research (ISSCR). Topics covered in the booklet include: what are stem cells, the risks and benefits associated with different types of stem cell treatments, and the difference between treatments offered by private clinics and those offered within clinical trials. The booklet is expected to take approximately 30 minutes to read and participants will need to do so at that time. After confirming that they have read the booklet, participants will be asked to recomplete the previous survey about experimental stem cell treatments. The first stage of the study ends here for Arm 1. Participants will then be emailed 30-days after completing this stage to reconfirm their attitudes toward experimental stem cell treatments by completing the previously administered survey.
Arm 2:
Participants in Arm 2 will then be directed via a web link to watch a patient information video (1.17 minutes in length) produced by the Stem Cell Network. Topics covered in the video include: the current state of stem cell treatment research, the risks associated with having experimental stem cell treatments, and how researchers and regulatory bodies determine if treatments are safe and effective for patients to use. After confirming that they have watched the video, participants will be asked to recomplete the previous survey about experimental stem cell treatments. The first stage of the study ends here for Arm 2. Participants will then be emailed 30-days after completing this stage to reconfirm their attitudes toward experimental stem cell treatments by completing the previously administered survey.

Behaviour
Comparator / control treatment
Participants in Arm 3 will be asked to provide the same background information (e.g., age, gender, stroke type/year) and details of their current physical, cognitive and emotional functioning as Arms 1 and 2. Participants will also be asked to complete a brief survey (6 questions) about experimental stem cell treatments (e.g. perceived risks, benefits, accessibility, affordability). Following this, participants in Arm 3 will not be required to read or view any resources. Instead, they will be emailed 30-days after providing their initial responses to reconfirm their attitudes toward experimental stem cell treatments by completing the previously administered survey. Once this has been completed, participants in Arm 3 will be provided with web links to the booklet and video given to Arms 1 and 2.

Eligibility
Key inclusion criteria
English-speaking, adult, stroke survivors who have not previously had experimental stem cell injections, either as a treatment for their stroke/stroke-related symptoms (e.g. pain), or any other medical or neurological disorder, and who are able to provide consent (personally or via a third party).
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Stroke survivors aged less than 18 years (at time of survey) and/or have previously had experimental stem cell injections, either as a treatment for their stroke/stroke-related symptoms (e.g. pain), or other medical or neurological disorder.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will contact the holder of the allocation schedule (via email) who will be located at a central administration site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation).
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?

Type of endpoint/s
Efficacy
Statistical methods / analysis
A 3 x 3 mixed model analysis of variance (ANOVA) will be conducted to statistically compare the mean response scores for the patient information booklet (Arm 1), patient information video (Arm 2), and control (Arm 3) groups for four assessable items (perceived safety, effectiveness, accessibility, affordability of experimental stem cell treatments) across the three time points (i.e. pre-intervention, immediately post-intervention, 30-day post-intervention).

A minimum of 108 participants (i.e. 36 respondents per Arm) will be required to detect moderate effect sizes (F statistics greater than or equal to 0.25) between the three groups (patient information booklet, video, control) across three time points (pre-intervention, immediately post-intervention, 30-days post-intervention), with 80% chance at an alpha level of .05. However, allowing for an estimated 30% attrition rate (estimate based on previous survey), 159 participants will be recruited initially (i.e. 53 respondents per group).
