NCT05363046

Brief Summary

This study aims to evaluate the impact of the frequency of assessments on the variability over time, reliability, and compliance for the Parkinson's disease (PD) diary in patients with PD in whom medications do not provide adequate control of symptoms.

Outcome Measures

Primary Outcomes (3)

  • Change in Good ON-time as measured by the PD Diary.

    Standard deviation of change in ON-time without troublesome dyskinesia (Good ON-time) as measured by the PD diary.

    Baseline, 3, 6, 12, 18 and 24 months.

  • Individual participant variability for ON-time without troublesome dyskinesia (Good ON-time) as measured by the PD diary.

    Within-subject coefficient of variation for ON-time without troublesome dyskinesia (Good ON-time) as measured by the PD diary.

    Baseline, 3, 6, 12, 18 and 24 months.

  • Proportion of valid PD Diaries.

    Proportion of valid PD Diaries.

    Baseline, 3, 6, 12, 18 and 24 months.

Study Arms (2)

Group A

Participants will complete the PD diary on 3 consecutive days in 1 week.

Group B

Sampling MethodProbability Sample
Study Population

Parkinson's disease patients whose medications do not provide adequate control of their symptoms.

You may qualify if:

  • ≥39 to ≤70 years of age at signing of informed consent
  • Diagnosis of clinically established PD as defined by the Movement Disorder Society (MDS) Clinical Diagnostic Criteria for PD
  • Marked levodopa responsiveness at screening per investigator's judgment (eg, an estimated ≥30% improvement of MDS-UPDRS Part III score in the off-medication versus on-medication state)
  • A minimum of 3 years and a maximum of 10 years from time of PD diagnosis to the date of screening
  • Receiving optimized and stable PD medical therapy for ≥1 month prior to screening or demonstrated intolerance to PD medications per investigator's judgment in agreement with the medical monitor
  • ≥2 hours of average daily OFF-time assessed within 3 months of screening by PD diary or per investigator's judgment
  • Hoehn and Yahr Stage of 1 to 3 while on PD medication assessed within 3 months of screening or at screening
  • Normal cognition as determined by the investigator after review of relevant testing (eg, Montreal Cognitive Assessment score of ≥26, or ≥22 if no significant cognitive impairment as determined by neuropsychological testing)

You may not qualify if:

  • PD with risk of recurrent falls or only tremor-based symptoms
  • Diagnosis of primary mitochondrial disorder, epilepsy, stroke, multiple sclerosis, or clinical features suggestive of a neurodegenerative disease other than PD such as Alzheimer's disease
  • Any available evidence inconsistent with dopamine deficiency (eg, 18F-DOPA positron emission tomography \[PET\] or dopamine transporter single-photon emission computed tomography \[DAT-SPECT\] imaging if performed)
  • Moderately severe dyskinesia per investigator's judgment
  • Receiving dopamine receptor-blocking agents, including typical neuroleptics, prochlorperazine, and metoclopramide at the time of screening or within 3 months prior to screening
  • Treatment with intrajejunal or subcutaneous infusion therapies for PD within 2 months of screening
  • History of gene therapy or cell therapy
  • Prior surgical or radiation therapy to the brain, including deep brain stimulation and lesion therapy, or prior history of intradural spinal cord surgery
  • Receipt of another investigational therapy or device within 2 years of screening unless approved by the medical monitor
