NCT04764669

Brief Summary

The purpose of study is to demonstrate the pharmacodynamic (PD) effects of E2027 on cerebrospinal fluid (CSF) cyclic guanosine monophosphate (cGMP) in participants with DLB and PDD with and without amyloid copathology after 9 weeks of treatment.

Outcome Measures

Primary Outcomes (1)

  • Percent Change From Baseline in Cerebrospinal Fluid (CSF) Cyclic Guanosine Monophosphate (cGMP) at Week 9

    cGMP was measured in CSF samples using a validated liquid chromatography with tandem mass spectrometry (LC-MS/MS) method with a lower limit of quantitative at 0.500 nanogram per milliliter (ng/ml). Evaluation of cGMP following dosing of E2027 was based on relative percent change from baseline.

    Baseline, Week 9

Secondary Outcomes (7)

  • Number of Participants With Treatment Emergent Adverse Events (TEAEs), Severe TEAEs, Serious TEAEs, Adverse Events (AEs) Resulting in Study Discontinuation

    From first dose of study drug up to Week 16

  • Number of Participants With Treatment Emergent Orthostatic Hypotension

    Week 3, Week 6, Week 9, Week 12 and Week 16

  • Number of Participants With Post Baseline Treatment Emergent Orthostatic Tachycardia

    From first dose of study drug up to Week 16

  • Number of Participants With Markedly Abnormal Laboratory Values

    From first dose of study drug up to Week 16

  • Number of Participants With Post-Baseline Abnormal Electrocardiogram (ECG) Findings

    From first dose of study drug up to Week 16

  • +2 more secondary outcomes

Eligibility Criteria

Age50 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female, age 50 to 85 years, inclusive at time of consent
  • Meet criteria for probable DLB (as defined by the 4th report of the DLB Consortium) or meet criteria for probable PDD (as defined by the task force of the Movement Disorder Society).
  • Mini-mental state examination (MMSE) greater than (\>) 14 and less than (\<) 26 at Screening Visit
  • For DLB participants, have experienced visual hallucinations since onset of their DLB
  • If receiving acetylcholinesterase inhibitors (AChEIs), must have been on a stable dose for at least 12 weeks before Screening Visit, with no plans for dose adjustment during the study. Treatment naive participants can be entered into the study but there should be no plans to initiate treatment with AChEIs from Screening to the end of the study.
  • If receiving memantine, must have been on a stable dose for at least 12 weeks before Screening Visit, with no plans for dose adjustment during the study. Treatment naive participants can be entered into the study but there should be no plans to initiate treatment with memantine from Screening to the end of the study.
  • If receiving Parkinson's disease medications, must have been on a stable dose for at least 4 weeks before Screening Visit, with no plans for dose adjustment during the study.
  • Must have an identified caregiver or informant who is willing and able to provide follow up information on the participant throughout the course of the study.
  • Provide written informed consent.

You may not qualify if:

  • History of transient ischemic attacks or stroke within 12 months of Screening
  • Modified Hachinski Ischemic Scale \>4
  • Parkinsonian (extrapyramidal) features with Hoehn and Yahr Scale (HYS) stage 4 or higher
  • Any major psychiatric diagnosis, including schizophrenia, bipolar disorder and current major depressive disorder as per Diagnostic and Statistical Manual of Mental Disorders Fifth Edition
  • Geriatric Depression Scale (GDS) score \>8
  • Severe visual or hearing impairment that may interfere with the participant study assessments including cognitive testing
  • Any contraindications to lumbar puncture
  • History of deep brain stimulation or other neurosurgical procedure for Parkinson's disease
  • Has thyroid stimulating hormone (TSH) above normal range
  • Abnormally low serum vitamin B12 levels (\< the lower limit of normal \[LLN\]) for the testing laboratory
  • Contraindications to MRI scanning
  • Evidence of other clinically significant lesions that suggest a dementia diagnosis other than DLB or PDD on brain MRI at Screening
  • Other significant pathological findings on brain MRI at Screening
  • Hypersensitivity to E2027 or any of the excipients
  • A prolonged corrected QT interval calculated using Fridericia's formula (QTcF) as demonstrated by triplicate ECG at the Screening or Baseline Visit (that is, mean value \>450 millisecond \[msec\])
  • +14 more criteria
