- Registration Number
- NCT04381065
- Lead Sponsor
- Global Kinetics Corporation
- Brief Summary
The main objective of this study is to evaluate whether persons with Parkinson's disease (PwP) whose Parkinson's disease (PD) symptoms are uncontrolled have improved clinical patient outcomes and quality of life when managed with the aid of objective measurement and use of PKG target ranges compared to PwP treated using only standard of care (SOC) (medical history, physical examination).
- Detailed Description
This is a randomized controlled trial (RCT) to compare the value of the Personal KinetiGraph® (PKG®) System and SOC vs. the SOC alone for treatment of PwP. The study aims to evaluate clinical outcomes, quality of life outcomes, health economic benefits, duration of controlled status, and need for additional PD treatment through 3 years follow-up of PwP specifically treated to a target range when using the PKG data in the clinical management of PD in routine clinical care compared to those managed with SOC alone. All subjects will be treated by Movement Disorder Specialists and General Neurologists with expertise in PD. Both groups will be recommended to undergo treatment changes until they reach a "controlled state" that is determined by either the clinician using SOC (PKG- Group) or using recommended target ranges for PKG scores and SOC assessments (PKG+ Group). Investigators will utilize standard available treatments to manage these PwP in both groups.

Group Intervention Description PKG- Group Personal KinetiGraph® (PKG®) Watch For subjects in the PKG- Group, participants will wear the PKG watch prior to all study visits, however the investigator will not have access to the PKG report and will use standard of care to determine clinical treatment plans. PKG+ Group Personal KinetiGraph® (PKG®) System For subjects in the PKG+ Group, participants will wear the PKG watch prior to all study visits in which the study investigator will review and report on the PKG prior to the visit and use the information to guide the discussion with the subject during the clinical assessment.The PKG will be used to determine if the subject is in the target range or out of the target range based on scores provided by the PKG.
- Primary Outcome Measures
Name Time Method Change in Patient Outcomes using Movement Disorder Specialist - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) 4 months The change in MDS-UPDRS Total score at 4 months from baseline defined as sections I, II, III (per core lab measurement) and IV in PwP. The endpoint will be compared between subjects out of target at baseline for those who are treated with SOC and PKG data (PKG+ Group) versus those who are treated per SOC alone (PKG- Group).
- Secondary Outcome Measures
Name Time Method Number of Interim Visits 4 months Number of interim visits conducted from baseline to 4 months in each arm
Change in MDS-UPDRS total 1 year, 2 years, 3 years Change in MDS-UPDRS Total score from baseline. The Movement Disorder Specialist - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) evaluates motor and non-motor symptoms in persons with Parkinson's and consists of 4 parts with various questions and evaluations. Parts I and II (non-motor) each contain 13 questions/evaluations, Part III (motor) contains 33 and Part IV (motor) contains 6. Each question/evaluation score ranges from 0 (normal) to 4 (severe). Higher scores indicate a greater impact of Parkinson's disease symptoms (i.e., worse symptoms).
Change in MDS-UPDRS sub parts 4 months, 1 year, 2 years, 3 years Change in the non-motor (parts I and II) score and change in Part IV for the MDS-UPDRS from baseline. The Movement Disorder Specialist - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) evaluates motor and non-motor symptoms in persons with Parkinson's and consists of 4 parts with various questions and evaluations. Parts I and II (non-motor) each contain 13 questions/evaluations, Part III (motor) contains 33 and Part IV (motor) contains 6. Each question/evaluation score ranges from 0 (normal) to 4 (severe). Higher scores indicate a greater impact of Parkinson's disease symptoms (i.e., worse symptoms).
Change in PKG Dyskinesia score (DKS) 4 months, 1 year, 2 years, 3 years Change in the PKG reported DKS from baseline. A higher score represents more severe dyskinesia.
Change in Fluctuation Dyskinesia score (FDS) 4 months, 1 year, 2 years, 3 years Change in the PKG reported FDS from baseline. The higher the score, the more severe the fluctuation, and a FDS of 7.5-13 indicates controlled fluctuations.
Responder rate for total MDS-UPDRS 4 months Percent "responders" for total MDS-UPDRS based on a minimal clinically important change of \>4 points (Shulman LM, Gruber-Baldini AL, Anderson KE, et al. The Clinically Important Difference on the Unified Parkinson's Disease Rating Scale. Arch Neurol 2010: 67(1):64-70.). The Movement Disorder Specialist - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) evaluates motor and non-motor symptoms in persons with Parkinson's and consists of 4 parts with various questions and evaluations. Parts I and II (non-motor) each contain 13 questions/evaluations, Part III (motor) contains 33 and Part IV (motor) contains 6. Each question/evaluation score ranges from 0 (normal) to 4 (severe). Higher scores indicate a greater impact of Parkinson's disease symptoms (i.e., worse symptoms).
Change in PKG Bradykinesia Score (BKS) 4 months, 1 year, 2 years, 3 years Change in the PKG reported BKS from baseline. A higher score represents more severe bradykinesia.
Change in Percent Time in Tremor (PTT) 4 months, 1 year, 2 years, 3 years Change in the PKG reported PTT from baseline, max 100%. A PTT of \>1% indicates that tremor is present.
Change in Parkinson's Disease Questionnaire-39 questions (PDQ-39) 4 months, 1 year, 2 years, 3 years Change in the patient reported quality of life questionnaire PDQ-39 from baseline. The PDQ-39 is a 39-item self-report questionnaire, which assesses Parkinson's disease-specific health related quality of life issues across 8 dimensions. Each dimension total score range from 0 (never have difficulty) to 100 (always have difficulty). Lower scores reflect better quality of life.
Responder rate for PKG 4 months Percent "responders" by PKG (defined as BKS change of \>2 point improvement)
Change in MDS-UPDRS motor endpoints 4 months, 1 year, 2 years, 3 years Change in MDS-UPDRS Part III (per core lab measurement). The Movement Disorder Specialist - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) evaluates motor and non-motor symptoms in persons with Parkinson's and consists of 4 parts with various questions and evaluations. Part III is the motor examination and contains 33 questions/evaluations. Each question/evaluation score ranges from 0 (normal) to 4 (severe). Higher scores indicate a greater impact of Parkinson's disease symptoms (i.e., worse symptoms).
Change in Percent Time Immobile (PTI) 4 months, 1 year, 2 years, 3 years Change in the PKG reported PTI from baseline, max 100%. A PTI of \>5% is considered high.
