Clinical Trial Summary

The purpose of the ROAM-DBS study is to compare the time needed to achieve a 1 point improvement Patient's Global Impression of change (PGIC) relative to the subject's status at the end of the ADROIT initial programming visit in subjects who receive programming updates via in-clinic sessions and subjects who additionally have the option of receiving programming updates via Virtual Clinic sessions. The study intends to demonstrate shorter times to achieve benefit in the Virtual Clinic cohort.

Description:

The ROAM-DBS study is a prospective, multi-center, randomized control, open-label, post-market cohort study intended to gather clinical data on the effect of the NeuroSphere Virtual Clinic feature (remote care) on the time needed to optimize DBS stimulation parameters after implant. The study will enroll up to 100 subjects from up to 15 centers in geographies where Abbott DBS systems with the Virtual Clinic feature are approved, which may include North America, and Europe. Subjects should be participants in the ADROIT study (NCT04071847). Subjects will be followed to a 3 month visit where the primary endpoint will be assessed. Subjects will be further followed for 1 year for final data assessment. Subjects will remain enrolled in ADROIT after the end of the ROAM study, and will complete the ADROIT 6 month and 1 year visits under that protocol. The study is expected to enroll subjects for up to 2 years, and complete all follow-up visits within 3 years.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Primary Efficacy Endpoint: The time to achieve a 1 point improvement Patient's Global Impression of change (PGIC) relative to the subject's status at the end of the initial programming visit	The PGI consists of 2 subscales, the first rating the severity of illness (PGIS) and the second evaluating the change in illness relative to a previous status (PGIC). The PGI scale evaluates all aspects of health and assesses if there has been a change in clinical status. The scale consists of two items, one scale rating severity of illness and one rating global improvement. Severity is rated from 1=normal/not at all ill to 7= extremely ill. Global improvement is rated from 1=very much improved to 7=very much worse. The questionnaire takes approximately 5 minutes to complete. The time needed to achieve a 1 point improvement Patient's Global Impression of change (PGIC) relative to the subject's status at the end of the initial programming visit in subjects who receive programming updates via in-clinic sessions and subjects who additionally have the option of receiving programming updates via Virtual Clinic sessions, will be compared.	PGIC will be collected within 2 days (48 hours) after completion of each programming visit
Primary	Primary Safety Endpoint: Rate of programming related adverse events for the Virtual Clinic cohort	The rate of programming related adverse events reported up to the Short Term (3 month) follow-up visit for the Virtual Clinic cohort will be summarized using counts and percentages.	At 3-months after initial programming visit
Secondary	Patient Global Impression (PGI)	The PGI consists of 2 subscales, the first rating the severity of illness (PGIS) and the second evaluating the change in illness relative to a previous status (PGIC). The PGI scale evaluates all aspects of health and assesses if there has been an improvement or decline in clinical status. The scale consists of two items, one scale rating severity of illness and one rating global improvement. Severity is rated from 1=normal/not at all ill to 7= extremely ill. Global improvement is rated from 1=very much improved to 7=very much worse. The clinical scores of virtual Clinic cohort will be compared to the in-clinic cohort.

Secondary	Parkinson's Disease Questionnaire (PDQ-39)	PDQ-39 questionnaire is a widely used validated questionnaire to measure PD-specific health status (16-17). The self-administered questionnaire consists of 39 questions and assesses how often the subject has experienced difficulties during the past month due to PD across 8 dimensions including mobility, activities of daily living, emotional well-being, social support, cognition, communication and bodily discomfort. Each question is rated on a 5-point ordinal scoring system ranging from 0=never to 4=always. Each dimension total score ranges from 0 (never have difficulty) to 100 (always have difficulty). The overall score is expressed by a Summary Index. Lower scores reflect better quality of life. The clinical scores of virtual Clinic cohort will be compared to the in-clinic cohort.

Secondary	Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS)	MDS-UPDRS questionnaire is a widely used validated questionnaire to assess the severity of Parkinson's disease. This questionnaire is composed of four sections, however, this study shall only utilize part III: motor examinations consisting of 33 scores based on 18 questions with several right, left or other body distribution scores. Each item is scored from 0 to 4, where 0 indicates normal, 1 indicates slight symptoms, 2 indicates mild symptoms, 3 indicates moderate symptoms, and 4 indicates severe symptoms. The total score is obtained from the sum of the corresponding item scores. Higher scores indicate greater impact of PD symptoms. The clinical scores of virtual Clinic cohort will be compared to the in-clinic cohort.	At 1 Year after initial programming visit
Secondary	Home Monitoring (Tremor)	Subjects will be provided with a home monitoring kit consisting of a smart watch and smart phone and will be instructed on how to use and charge the devices in order to monitor the prevalence and severity of tremor during activities of daily living. The supplied smart phone will also provide a diary function that subjects will use to maintain notes on symptoms and medications. The smart watch data provides time stamped data indicating the presence of tremor, and its severity (slight (< 0.1 cm), mild (0.1-0.6 cm), moderate (0.6-2.2 cm),strong (>2.2 cm) and absent during each one-minute interval). The Home Monitoring equipment is validated against physician assessments of tremor. Home Monitoring data is uploaded and stored in a secured cloud server.	At 3-months after initial programming visit
Secondary	Home Monitoring (Dyskinesia)	Subjects will be provided with a home monitoring kit consisting of a smart watch and smart phone and will be instructed on how to use and charge the devices in order to monitor the prevalence and severity of dyskinesia during activities of daily living.

The smart watch data provides the % of time in each 15 minute interval the subject experiences dyskinesia. The Home Monitoring equipment is validated against physician assessments of dyskinesia. Home Monitoring data is uploaded and stored in a secured cloud server.	At 3-months after initial programming visit
Secondary	"On Time" (time each day without troublesome symptoms or side effects) (derived from Home Monitoring)	"On Time" (time each day without troublesome symptoms or side effects) will be assessed by summing the daily intervals where Home Monitoring data does not measure tremor or dyskinesia	At 3-months after initial programming visit
