A Safety and Tolerability Study of JNJ-54861911 in Participants With Early Alzheimer's Disease

Alzheimer's Disease Clinical Trial

Official title: A Phase 2a Randomized, Double-blind, Placebo-Controlled, Parallel-Group, Multi-center Study Investigating the Safety and Tolerability of JNJ-54861911 in Subjects With Early Alzheimer's Disease

Status Completed

Clinical Trial Summary

The purpose of this study is to evaluate the long-term safety and tolerability of JNJ-54861911 during 6 months of treatment in participants with early (predementia) alzheimer's disease (AD [degenerative disease of the brain characterized by the insidious onset of dementia, impairment of memory, judgment, attention span, and problem solving skills are followed by severe apraxias and a global loss of cognitive abilities]).

Clinical Trial Description

This is a double-blind (neither the researchers nor the participants know what treatment the participant is receiving), placebo-controlled (an inactive substance; a pretend treatment [with no drug in it] that is compared in a clinical trial with a drug to test if the drug has a real effect), randomized (study drug assigned by chance), multi-center (when more than one hospital or medical school team work on a medical research study), parallel-group study. The study consists of 3 Parts; Screening Phase of 90 days, double-blind Treatment Phase of 6 months and Follow-up Phase of 7 to 28 days following the last dose in Month 6. Eligible participants in the early (predementia) AD spectrum will be randomized to either Treatment group 1, 2 or placebo and participants who previously participated in study 54861911ALZ1005 will be enrolled in this study and will receive the same treatment as in study 54861911ALZ1005. The study duration for each participant will be approximately 10 months. Blood and cerebrospinal fluid (CSF) samples will be collected to evaluate the plasma pharmacokinetics of JNJ-54861911, as well as amyloid beta fragments. Participants' safety will be monitored throughout the study, including magnetic resonance imaging (MRI) and cognitive measures. ;
