Assessing Tele-Health Outcomes in Multiyear Extensions of PD Trials

The Fox Insight MDS-UPDRS (Movement Disorders Society Unified PD Rating Scale) Part II score comprises patient-reported responses to 13 questions on motor experiences of daily living. Participants report their responses online through the Fox Insight web-based platform. The response to each question is assessed on a 5-point Likert scale ranging from 0 to 4 where higher scores imply worse symptoms. Part II scores may range from a minimum of 0 to a maximum of 52, with higher values meaning worse symptoms.

Time frame: Two years (0, 6, 12, 18, and 24 months)

The Smartphone Tapping Score is derived from a 30-second finger tapping task performed separately for each hand. The score ranges from 0 to 1 and higher scores are worse.

Time frame: Two years (0, 3, 6, 9, 12 , 15, 18, 21, and 24 months)

Population: Only subjects who consented and enrolled in the smartphone assessments are included in the analysis.

The response to each question is assessed on a 5-point Likert scale ranging from 0 to 4 where higher scores imply worse symptoms. Part II scores may range from a minimum of 0 to a maximum of 52, with higher values meaning worse symptoms.

Participants will be asked to complete (from home or other preferred environment) an hour-long Tele-visit that includes the Movement Disorders Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS), comprising MDS-UPDRS part 1a and (modified) part 3, as well as completion or confirmation of patient-reported component parts 1b and 2. The MDS-UPDRS is assessed on a 5-point Likert scale ranging from 0 to 4 where higher scores imply worse features. Parts I-III contain 59 total questions (13 in Part I, 13 in Part II, and 33 in Part III). Total scores are calculated as simple sums of component items with mean imputation by Part if no more than 1, 2, or 7 items are missing for Parts I through III, respectively. Total scores may range from 0 to 236, with 0 meaning no symptoms and 236 meaning worse symptoms.

Time frame: Two years (0, 12, and 24 months)

The Fox Insight EQ-5D (European Quality of life survey) is a standardized measure of health-related quality of life assessing five dimensions of health. It comprises five corresponding questions on mobility, self-care, pain, usual activities, and psychological status with three possible answers for each item (1=no problem, 2=moderate problem, 3=severe problem). A derived summary index score is higher with better health-related quality of life. A maximum of 1 corresponds to the best quality of life, whereas a score of 0 is intended to approximate a state equivalent to death, with values less than 1 corresponding to a state worse than death.

Time frame: Two years (0, 6, 12, 18, and 24 months)

The Geriatric Depression Scale (GDS) is a measure of depression completed by the participant online in Fox Insight. The scale has 30 yes/no questions, with each question having a maximum score of 1 and a total possible score ranging from 0 to 30. The higher the score, the greater the depression.

Time frame: Two years (0, 12, and 24 months)

The Non-motor Symptoms Questionnaire (NMS-QUEST) is a 30-question self-reported assessment. Each question is of a yes/no format with a score of 1 given to each yes answer, with total scores ranging from 0-30, with higher scores indicating a greater number of non-motor symptoms. Participants completed the assessment online in Fox Insight.

Time frame: Two years (0, 3, 6, 9, 12, 15, 18, 21, and 24 months)

The Parkinson's Daily Activities Questionnaire -15 (PDAQ-15) is a 15-item measure of activities of daily living (ADL) that are impacted by cognitive impairment in participants with Parkinson's disease. The PDAQ-15 is derived from the original 50-item scale and is completed by the participant in Fox Insight. Scores range from 0 to 60, with higher scores indicating better function.

Time frame: Two years (0, 3, 9, 15, and 21 months)

The Fox Insight PDQ-8 (Parkinson's Disease Questionnaire, short-form 8 item version) is a self-administered questionnaire used to measure quality of life in persons with Parkinson's disease. The response to each question is assessed on a 5-point Likert scale ranging from 0 to 4 where higher scores imply worse symptoms. Scores range from a minimum of 0 to a maximum of 32, with a higher score indicating a poorer quality of life.

Time frame: Two years (0, 3, 6, 9, 12, 15, 18, 21, and 24 months)

The Fox Insight Rapid Eye Movement Behavior Disorder (RBD) score is a patient-reported binary (no or yes) response to a single question of whether they act out their dreams while asleep. Participants report their response online through the Fox Insight web-based platform. The score value is dichotomous (or missing) and ranges from 0 (no symptom) to 1 (yes response).

Time frame: Two years (0, 3, 6, 9, 12, 15, 18, 21, and 24 months)

The Clinician Global Impression (CGI) is an observer-rated scale that measures illness severity (CGIS). The CGIS is rated on a 7-point scale, with the severity of illness scale using a range of responses from 1 (normal) through 7 (amongst the most severely ill patients).

Time frame: Two years (0, 12, and 24 months)

Participants will be asked to complete (from home or other preferred environment) an hour-long Tele-visit that includes the Movement Disorders Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS), comprising MDS-UPDRS part 1a (i.e., the first six questions of part 1). The MDS-UPDRS is assessed on a 5-point Likert scale ranging from 0 to 4 where higher scores imply worse features. Part 1a scores may range from a minimum of 0 to a maximum of 24, with higher values meaning worse disability.

Time frame: Two years (0, 12, and 24 months)

The Movement Disorders Society Unified PD Rating Scale (MDS-UPDRS) Part Ib is the patient-reported portion of Part I, and assesses non-motor experiences of daily living. The MDS-UPDRS is assessed on a 5-point Likert scale ranging from 0 to 4 where higher scores imply worse symptoms. Part Ib contains 7 questions, and its scores may range from a minimum of 0 to a maximum of 28, with higher values meaning worse symptoms.

Time frame: Two years (0, 12, and 24 months)

Participants will be asked to complete (from home or other preferred environment) an hour-long Tele-visit that includes the Movement Disorders Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS), comprising MDS-UPDRS (modified) part 3. This measure omits 5 questions related to rigidity and 1 question related to postural instability, with a range from 0 to 108. The MDS-UPDRS is assessed on a 5-point Likert scale ranging from 0 to 4 where higher scores imply worse features.

Time frame: Two years (0, 12, and 24 months)

The Montreal Cognitive Assessment (MoCA) assesses attention and concentration, executive functions, memory, language, visuoconstructional skills, conceptual thinking, calculations, and orientation. Points are awarded for the correct completion of MoCA tasks. Scores for each task are summed for a total score (range 0-30). Higher scores indicate greater cognitive capacity.

Time frame: Two years (0, 12, and 24 months)

The Schwab and England scale is a Site Investigator and subject assessment of the subject's level of independence. The subject will be scored on a percentage scale reflecting his/her ability to perform acts of daily living. Printed scores with associated descriptors range from 0% to 100% in increments of 5%, with higher percentages associated with more independence. A score of 0% implies vegetative functions such as swallowing, bladder and bowel functions are not functioning; bedridden. A score of 100% implies subject has full ability and is completely independent; essentially normal.

Time frame: Two years (0, 12, and 24 months)
