Utility of At-home Monitoring of Exercise Capacity by App-based 6-minute Walk Test

United States63 participantsStarted 2020-07-01

Plain-language summary

* Evaluate for accuracy and reproducibility of data collected via the participant-operated Walk.Talk.Track. (WTT) app combined with Apple Watch during in-clinic, technician proctored 6MWT's. * Determine whether the WTT app on the Apple Watch can accurately collect information on distance traveled and heart rate (HR) during in-clinic 6MWT run by American Thoracic Society (ATS) guidelines * Determine whether participants can operate the WTT app and Apple Watch effectively to gather accurate data in a monitored and home-based setting * Prospectively monitor for changes in WTT app recorded 6MWT results following initiation of therapy in a treatment naïve cohort of PAH participants * Evaluate whether changes from baseline in 6 minute walk distance (6MWD) and heart rate recovery at one minute (HRR1) as well as other variables that have been associated with disease severity in PAH and left-sided heart disease (resting HR, heart rate variability \[HRV\], chronotropic index \[CI\]) can be identified before the 12-week follow up when comparing the treatment arm and the control arm * Evaluate whether changes from baseline in the HRR1, resting HR, HRV and/or CI are more evident in treatment responders when compared to treatment non-responders.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
