Study Description

Brief 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]).

Condition or disease	Intervention/treatment	Phase
Alzheimer's Disease	Drug: JNJ-54861911, 10 milligram (mg); Drug: JNJ-54861911, 50 mg; Drug: Placebo	Phase 2

Detailed 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.

Outcome Measures

Primary Outcome Measures :

1. Number of Participants With Adverse Events (AEs) or Serious Adverse Events (SAEs) [ Time Frame: up to 10 months ]
   An AE is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; lifethreatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.

Secondary Outcome Measures :

1. Relationship Between Dose and Exposure of JNJ-54861911 With Safety [ Time Frame: Month 1 up to Month 6 ]
   Plasma and, if possible, CSF measurements will be taken to measure the concentration of JNJ-54861911. Population pharmacokinetic modeling (statistical modeling) will be used to derive individual pharmacokinetic parameters (e.g. Cmax, AUCtau, Tmax) in plasma and, if possible, in CSF. Incidence of adverse events and their timing of onset will be examined with regard to these concentrations to assess potential relationships between safety and exposure.
2. Percent Change From Baseline in Cerebrospinal Fluid (CSF) Amyloid Beta (ABeta) (1-37, 1-38, 1-40, 1-42) Levels and Soluble Amyloid Precursor Protein (sAPP) Fragments (sAPP-alpha, sAPP-beta), Total sAPP Levels [ Time Frame: Baseline and Month 6 ]
   The CSF samples will be obtained for measuring levels of different ABeta fragments such as ABeta 1-37, ABeta 1-38, ABeta 1-40, ABeta 1-42. ABeta fragments of different length are produced by cleavage of the APP by beta-secretase (BACE) and the gamma-secretase complex in the brain and excreted into CSF. For participants, who participated previously in study 54861911ALZ1005, the baseline CSF sample taken during that study may be used as baseline in this study.
3. Percent Change From Baseline in Plasma ABeta 1-40 Levels and sAPP Fragments (sAPP-alpha, sAPP-beta), Total sAPP Levels [ Time Frame: Baseline and Month 6 (Day 168) ]
   Plasma samples will be obtained for measuring levels of different ABeta fragments such as ABeta 1-37, ABeta 1-38, ABeta 1-40, ABeta 1-42. ABeta fragments of different length are produced by cleavage of the APP by beta-secretase (BACE) and the gamma-secretase complex in the different peripheral tissues, including white blood cells and can be measured in Plasma.
4. Relationship Between Changes in CSF and Plasma ABeta Species and sAPP Fragments With Safety [ Time Frame: Month 1 up to Month 6 ]
   ABeta species and sAPP fragments in plasma and CSF will be measured. Incidence of adverse events and their timing of onset will be examined with regard to these concentrations to assess potential relationships between safety and changes in the ABeta species and sAPP fragments.
5. Maximum Plasma Concentration (Cmax) of JNJ-54861911 [ Time Frame: Pre-dose on Day 1, post-dose on Day 28, 56, 84, 112, 140 and 168 ]
   The Cmax is the maximum observed plasma concentration.
6. Time to Reach the Maximum Plasma or CSF concentration (Tmax) [ Time Frame: Pre-dose on Day 1, post-dose on Day 28, 56, 84, 112, 140 and 168 ]
   The Tmax is the time to reach the maximum plasma or CSF concentration.
7. Area Under the Plasma/CSF Concentration-time Curve From Time 0 to tau Hours Post Dosing (AUCtau) [ Time Frame: Pre-dose on Day 1, post-dose on Day 28, 56, 84, 112, 140 and 168 ]
   AUCtau is the area under the plasma/CSF concentration-time curve from time 0 to tau hours post dosing. Time tau is the dosing interval.

• Participant has evidence of familial autosomal dominant AD. (Inclusion can be made upon written confirmation by sponsor, when the mutation is known and deemed not to be modulating Beta-secretase [BACE] cleavage)
• Participant with history or presence of significant depression as defined by the most current DSM criteria
• Participant has a clinically significant abnormal physical- or neurological examination, vital signs at screening or baseline (Day 1 predose)
