Evaluation of the Personal KinetiGraph™ (PKG™) to Improve Insight Into Parkinson's Disease Status

The primary objective is to understand the utility of Personal KinetiGraph movement recording system data in the clinical management of Parkinson's disease (PD) in routine clinical care at a movement disorders clinic. Specifically:

1. Measure medication use and clinical management plan changes in a large, multicenter cohort among participants undergoing a clinical assessment with an MDS in which the MDS reviews the participant's PKG during the clinical assessment in half of the enrolled participants (PKG + Group) and in half of the enrolled participants the MDS completes the clinical assessment without the PKG (PKG- Group). 2. Determine the association between frequency of medication changes, the PKG information, and other clinical assessments among participants with and without a PKG report of their PD motor status available to the clinician at the time of evaluation.

About this study

This is a prospective, multicenter, randomized controlled trial. The study consists of 3 phases as follows:

Randomization phase: subjects undergo screening, baseline, interim and 90-day follow-up visits

PKG+ Group (standard of care clinical evaluation plus use of PKG data)
PKG- Group (standard of care clinical evaluation without use of PKG data - the MDS is blinded to PKG data)
Randomization ratio will be 1:1 with assignments generated in advance of the start of the trial by the unblinded statistician who will provide a list containing group assignments that will be available in an Electronic Database (EDC) for site use.
The clinical investigator, study site staff, and subject will not be blinded to the randomization assignment during the randomization phase of the study
Open-label phase: at the end of the 90-day randomization phase visit for PKG- Group subjects, the MDS will report on the PKG and review it with the subject, the subject will complete follow-ups with the MDS using the PKG information during the clinical assessment following the same process as the PKG+ Group during the randomization phase
Extended open-label follow-up phase: annual follow-ups for all subjects at 1, 2, and 3 years during which the MDS will use the PKG information during clinical assessments for all subjects.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Able and willing to sign a written informed consent for study participation
Age 46 - 83 years at the time of consent (per PKG Indications for Use, see Technical Instructions Manual)
Responsive to dopaminergic medications

Exclusion criteria

Contraindication to increasing dopaminergic therapy, such as current or treated freezing gait, symptomatic postural hypotension, or bothersome hallucinations
Wheelchair bound or bedridden
Utilizing or planning advanced PD therapies (DBS, infusion, etc.)
History of delirium in the past year
In the investigator's or sponsor's opinion, subject has any unstable or clinically significant condition that would impair the participant's ability to comply with study requirements or interfere with interpretation of the study endpoints (e.g., subject able to complete PKG wear instructions per Patient Instruction Manual, or ability to comply with required study procedures and visit schedule)

Treatment and study plan

Personal KinetiGraph™ (PKG™)

Device

The Personal KinetiGraph™ (PKG™) Movement Recording System was developed by neurologists at the Melbourne-based Florey Institute of Neuroscience and Mental Health. The product is manufactured and marketed by Global Kinetics (GKC).

The Personal KinetiGraph™ (PKG™) Movement Recording System consists of the following:

A wrist-worn data logger designed to acquire data on the kinematics of movement disorder symptoms over a 6-10 day period.
An application to configure the data logger and transfer the acquired data at the end of a recording.
A series of algorithms that analyze the uploaded data, producing a report that is delivered to the clinician. The report contains objective data distinguishing the movement patterns consistent with tremor, bradykinesia, dyskinesia and immobility.

Primary outcomes

Evaluation of treatment changes with or without the use of PKG data

Time frame: 90 day

The proportion of patients in which the clinical management plan was changed in patients followed in the PKG- Group (clinician standard of care) compared to the PKG+ Group (clinician standard of care with the use of PKG data).
