Scratch Behavior Under Standard of Care


Brief description of study

Wrist-worn accelerometers and associated data analysis platforms will provide quantitative and qualitative knowledge regarding the action of scratching and sleep quantity in a symptomatic Atopic Dermatitis (AD) population. The overall research aim is to evaluate the sensitivity of digital devices to capture drug-induced (standard of care treatments; SOC) quantitative changes in nighttime scratch and sleep quantity in AD subjects. In the current study, the investigators aim to evaluate the ability of wrist-worn accelerometers to detect significant and clinically meaningful changes in scratch behavior and sleep quantity in patients with symptomatic AD aged 2 to 75 years, receiving topical SOC treatment for AD. To evaluate this experimental paradigm, using wearable accelerometers, traditional patient-reported outcome measures/observer-reported outcome (ObsRO) (PRO/ObsRO), thermal videography and physician assessments of AD will be assessed in a well-controlled observational methodology study that has both an in-patient and out-patient portions within the study.

Detailed Study Description

This open label study is to evaluate the ability of a wrist-worn accelerometry device to detect scratch and sleep quantity changes in patients with Atopic Dermatitis (AD) receiving Standard of Care (SOC) treatment. Subjects, age 2 to 75 years, with symptomatic AD will be recruited.

The study will be comprised of an initial screening/baseline clinic visit when subject will be diagnosed with symptomatic AD, screened and enrolled in the study after signing an informed consent (or parents/guardians and assent when appropriate). The subject will start or modify a SOC treatment course at the physician's discretion, and thereafter will be followed up for a total of 2 weeks for the purposes of the study. During those 2 weeks, the subject will wear two wrist worn accelerometry devices. The subject will also have to complete daily PRO/ObsRO related to itch, sleeping habits, quality of life, and device comfort questionnaires (parent/guardian will complete as appropriate) and may also participate in an optional daily photography taken of a single lesion (optional and for adult subjects only 18-75 years of age). The subject will also be asked to come and stay overnight at the sleep clinic for an overnight between Days 1-3, for thermal video recording overnight. An optional additional night (immediately following the first clinic overnight; between days 2-4) with video and polysomnography (PSG) may occur (subjects must be 18-75 years of age to participate in this aspect of the study). The subjects will be asked to return to the clinic on days 8 and 15 for clinician-based assessments. At the completion of the study, Day 15 (+3 day) the subjects will return the devices, and will complete PRO/ObsRO questionnaires.
