Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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
The intervention is a six-month text message support program in addition to usual care. Participants will receive four messages per week at random times and days for the duration of the program. Message topics include 1) general breast cancer information 2) social/emotional support, 3) diet/exercise and 4) medication adherence and side effects. The messages will be semi-personalised, where some contain the participant’s preferred name and are tailored for individual circumstances and preferences (eg. taking endocrine treatments or not). The messages are ‘one-way’, meaning that participants will not reply unless requesting withdrawal (‘STOP’). We have a purpose-built software system (software program and a centrally located research assistant with a clinical background) for safety monitoring of any replies and withdrawal (‘stop’) requests. A subset of participants (32/160) will wear accelerometers on their wrist for 7 days and resulting data will be used to validate the Global Physical Activity self-report scale.

Lifestyle
Comparator / control treatment
The control group will continue to receive usual care from their assigned health professionals, including access to breast care nurses, doctors and other allied health professionals. Participants in the usual care group will receive an initial text message welcoming them to the study, but they will not receive the text message support program. The control group will also receive a text-message reminder approximately six-months after their enrolment, notifying them that they will be contacted to schedule their six-month follow-up visit. Participants in the control group will be offered the opportunity to receive the intervention at the end of the study if they wish.

Can healthy volunteers participate?

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)
After the enrolment visit, participants will be randomly assigned to either usual care (control) or the text-message intervention group in a uniform 1:1 (control:intervention) allocation ratio, using a secured central computer-based randomisation service. For each participant, the computer system automatically produces a study identification number, which will be used on all study documents. Within three days after the enrolment visit, the computer system automatically sends the text message program to the participant. Therefore, the researcher conducting all face-to-face assessments remains blind to the study allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation using a randomisation table created by computer software with permuted blocks of 5 to minimise imbalances

Other design features
To validate the self-reported physical activity questionnaire, 20% (32/160) of participants will receive a second layer of randomisation, where they will be randomly assigned to wear a small (matchbox sized) accelerometer for seven days and return it to a member of the research team. Randomisation will be nested within each treatment arm at a ratio of 1:4, with permuted blocks of 5 to minimise imbalances. Sixteen participants with accelerometers will be in the text message intervention group and 16 participants will be in the control group.

Efficacy
Statistical methods / analysis
All analyses will be performed according to the intention-to-treat principle. Continuous variables will be summarised as means and corresponding 95% confidence intervals (CIs), or if the distribution is skewed, as medians and interquartile intervals. Categorical variables will be summarised as frequencies and percentages. Primary outcome will be compared between the intervention and the control groups at 6-months using analysis of covariance (ANCOVA), adjusting for the baseline measure of the primary outcome. A backward selection process will be performed to identify additional covariates. Similarly, for each of the secondary outcomes, ANCOVA, adjusting for the baseline value of the outcome, will be used to compare between the groups at 6-months, unless assumptions are violated, or the outcome variable is categorical, in which case appropriate analyses will be performed adjusting for baseline values. We will also investigate if changes in secondary outcomes are mediated by self-efficacy scores. A significance level of 0.05 will be used. All analyses will be undertaken using SAS 9.4 for Windows.
