Clinical Trial Summary

The purpose of this study is to determine the safety, tolerability and effect of JNJ-54861911 on level of amyloid-beta in Cerebrospinal Fluid (CSF) and plasma following 4 weeks of treatment in Japanese participants asymptomatic at risk for Alzheimer Dementia (ARAD) at the intended target dose range.

Description:

This is a multi-center (when more than one hospital or medical school team work on a medical research study), double-blind (neither physician nor participant knows the treatment that the participant receives), placebo-controlled (the experimental treatment or procedure is compared to an inactive substance), randomized (study medication assigned by chance), multiple dose, Proof of Mechanism (POM) study in Japanese participants ARAD. All eligible participants will be randomly assigned to 1 of 3 treatment groups (that is, placebo, JNJ-54861911 10 milligram [mg] or JNJ-54861911 50 mg once daily regimen). This study will consist of Screening Phase (8-week), Double blind Treatment Phase (4-week), and Follow-up Phase (2-week). The maximum study duration for a participant will be 14 weeks. Participant's safety will be monitored throughout the study.

Eligibility

Inclusion Criteria:

• Participant must have had sufficient education or work experience to exclude mental retardation based on Diagnostic and Statistical Manual of Mental Disorders 4th edition, Text Revision (DSM-IV-TR) and must be able to read and write and must have adequate hearing and visual acuity to complete the required psychometric tests

• Participant must have a Clinical Dementia Rating Scale- Japanese version (CDR-J) score of '0' and as such rated as normal

• Participant must have evidence of amyloid deposition as demonstrated by low Cerebrospinal Fluid (CSF) Amyloid (A)-beta 1-42 levels at Screening

• Participant must have a body mass index between 18 and 35 kilogram per square meter, inclusive, at Screening

• Participant must be otherwise healthy for their age group or medically stable with or without medication on the basis of physical examination, medical history, vital signs, and 12-lead electrocardiogram (ECG) performed at Screening or at Baseline

Exclusion Criteria:

• Participant has evidence of any brain disease other than potential very early signs of Alzheimer's disease (AD) or typical age related changes, or any other abnormality that could explain a possible cognitive deficit

• Participant has been diagnosed with dementia due to AD, due to other diseases, or with AD and contribution of other disorders (mixed dementia)

• Participant has evidence of familial autosomal dominant AD

• Participant has any contra-indications for Magnetic Resonance Imaging (MRI) (for example, prostheses, implants, claustrophobia, pacemakers, and others)

• Participant has a clinically significant abnormal physical- or neurological examination, vital signs or 12-lead ECG (including QTc greater than 450 millisecond for males and females, left bundle branch block, atrio-ventricular [AV] block second degree or higher, permanent pacemaker or implantable cardioverter defibrillator [ICD]) at Screening or Baseline, which in the opinion of the investigator is not appropriate and reasonable for the population under study
