Description of intervention(s) / exposure
The Remote-COR-B Intervention is an exercise intervention delivered using REMOTE technologies. Participants can take part anywhere they can access the internet.

The REMOTE- COR-B platform is comprised of a smartphone and wearable sensor (currently compatible with BioHarness 3, Zephyr Technology and the Polar10), and custom-built smartphone and web apps. The platform facilitates remotely supervised aerobic exercise prescription that is delivered, monitored and coached in real-time by a clinical exercise specialist.

The exercise specialists delivering the intervention will be qualified exercise professionals (either accredited exercise physiologists or physiotherapists) with experience and/or training in exercise prescription for cancer patients. All exercise specialists will be given an exercise prescription protocol to follow that will be updated as needed based on weekly check ins with trial staff.

Exercise prescription: Participants will be asked to participate in three remotely monitored aerobic exercise (e.g., walking, cycling) sessions per week for eight weeks with the aim of increasing cardiorespiratory fitness. The length of the session and exercise intensity will be individually tailored based on rate of perceived exertion (RPE, scale 0-10), objectively measured heart rate, medical history and symptoms reported prior to or during the exercise session.

Type: Walking is the preferred aerobic exercise mode but participants can choose other land-based exercise modes if preferred (e.g., cycling, jogging, rowing).

Frequency: There will be three remotely monitored sessions per week for eight weeks.

Duration: A minimum of 20 minutes each session will be completed where possible. The goal duration is 30-60 minutes.

Intensity: Exercise of at least a moderate intensity if advised.

Progression: The exercise principle of progressive overload will be used to facilitate continual improvement. It is recognised that in this setting maintenance of exercise dosage may reflect progression for some (e.g., those experiencing fluctuating, but persistent treatment-related side effects) and that small increments in intensity, load, duration and/or frequency will be used to generate overload as appropriate.

Participants will exercise with their smartphone (GPS enabled) and while wearing a heart rate sensor. The exercise specialist will monitor participants location, heart rate, RPE, and symptoms via a web-based platform, allowing them to provide individualised audio coaching, feedback and social support throughout the monitoring session, which is delivered to participants via earphones to optimise usability.

Outside of real-time interaction, participants receive 1-2 automatically generated push notifications per week containing general exercise education and behaviour change tips (1-4 sentences long). Topics include benefits of exercise for heart health, added benefits of incorporating flexibility and resistance-training exercises into weekly routines, strategies to overcome exercise barriers, increase exercise confidence, exercise enjoyment and develop long lasting exercise habits.

Participants can also review all recorded exercise performance data and set weekly intensity or duration goals (based on heart rate data) if they choose to. This is designed to be a brief task and is optional.

Participants will be considered adherent to the intervention if they complete at least 17 out of the 24 remotely-monitored exercise sessions (i.e., = 70%). This data is captured automatically by the intervention application.

Outcomes
Primary outcome [1] 328541 0
As embedding tailored exercise prescription into home-based programs is the key objective driving this program of work, the main outcome will be adherence to the tailored exercise sessions. This will be assessed in terms of percentage of exercise sessions completed (out of 24). This data is collected automatically via the heart rate sensor and the intervention application.

Eligibility
Key inclusion criteria
Participants must meet the following criteria to be included:
• Diagnosed with stage I-III breast cancer
• Be at risk of cardiotoxicity according to pre-determine criteria (taking treatment type and dose, as well as other common cardiovascular disease risk factors into account e.g., age, obesity, comorbidity)
• Have completed primary definitive anticancer therapy within the last 6 months (which may be surgery, radiotherapy or chemotherapy depending on if receiving adjuvant or neo-adjuvant treatment)
• Currently completing less than the REMOTE-COR-B target (target: greater than or equal to 150 minutes of moderate-vigorous intensity aerobic activity per week over 3 sessions or more per week; moderate-vigorous intensity exercise is defined as a score of 13 or above on the Borg Rating of Perceived Exertion (RPE) scale).
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 (Fully active, able to carry out pre-disease performance without restriction) – 2(Ambulatory and capable of selfcare but unable to carry out any work activities; up and about more than 50% of waking hours).
• Proficiency with the English language (Able to read and write in English to the extent they can read the information sheet, understand study directions and can meaningfully engage in the intervention).

Statistical methods / analysis
We aim to recruit 40 participants over nine months. This is equivalent to approximately 20-30% of the sample size needed in order to be adequately powered (80%) in our future definitive trial to demonstrate non-inferiority in V02 peak changes between groups (p value, 0.05); based on differences observed in our formative work.

This sample size is considered sufficient to test the feasibility of delivering the intervention, and of all other key trial parameters. Notably, with this sample size we will also have reasonable precision for estimating intervention adherence. For example, with n = 40, if the average adherence rate observed in the study is 70%, we can be sure with 95% confidence that the true population proportion is between 56% and 85%; 95%CI is ± 14.2. Given the potential reach of the intervention, and that adherence to current technology-based behaviour change programs is 50% this finding would warrant further investigation.


Data will be presented descriptively where appropriate; this includes for the majority of feasibility and acceptability outcomes, including the primary outcome (i.e., adherence to the intervention) as well as safety outcomes (e.g., number of adverse events, proportion of serious adverse events).

Changes over time in VO2 peak, patient-reported outcomes (quality of life and fatigue) and physical activity behaviour will be examined in exploratory analyses using mixed model repeated measures analyses. Unadjusted and adjusted models will be conducted, with adjustment for the following two baseline covariates in adjusted models: age and treatment pathway (adjuvant versus neo-adjuvant). Both adjusted and unadjusted models, as well as standardised coefficients will be reported with 95% confidence intervals to aid interpretation of clinical significance, rather than relying on p-values only. The unadjusted models will be considered the primary analysis. Choice of modelling link will be informed by residual diagnostics.
