Brief Summary:
The purpose of this study is to evaluate the long-term safety and tolerability of JNJ-54861911 in participants in the early Alzheimer's disease (AD [progressive brain disease that slowly destroys memory and thinking skills, and eventually even the ability to carry out the simplest tasks]) spectrum that have completed a Phase 1b or Phase 2 clinical trial with JNJ-54861911, who are willing to continue their assigned treatment.

Condition or disease Intervention/treatment Phase
Alzheimer Disease Drug: JNJ-54861911, 10 mg Drug: JNJ-54861911, 25 mg Drug: Placebo Drug: JNJ-54861911, 5 mg Phase 2

Detailed Description:
Participants in the early Alzheimer's Disease (AD) spectrum, enrolled in ongoing or future clinical trials with JNJ-54861911 (Phase 1b or Phase 2 studies) will be provided the opportunity to participate in this study upon completion of their treatment period under the parent protocol. The study will consist of a Screening phase and 2 sequential treatment phases (a 12-month double-blind [DB] treatment phase [placebo controlled] and an open-label [OL] phase [active]) followed by an End-of-Treatment visit. Treatment in OL phase will continue until registration of JNJ-54861911; unless safety issues emerge as determined by the Data Review Committee (DRC) that would warrant termination of the study. Blood and cerebrospinal fluid (CSF) samples will be collected to evaluate the plasma and CSF pharmacokinetics of JNJ-54861911, as well as amyloid beta fragments. Participants' safety will be monitored throughout the study.

Primary Outcome Measures :
  1. Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious TEAEs [ Time Frame: Up to 3 years ]
    An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. TEAEs were events between administration of study drug and up to 3 years that were absent before treatment or that worsened relative to pre-treatment state. An serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.


Secondary Outcome Measures :
  1. Double-blind Treatment Phase (Period 1): Percent Change From Baseline in Cerebrospinal Fluid (CSF) Amyloid Beta (ABeta) (1-37, 1-38, 1-40, 1-42) Levels [ Time Frame: Baseline, Double-blind (DB) Day 1 and DB Week 52 ]
    CSF samples were obtained for measuring levels of different ABeta fragments such as ABeta 1-37, ABeta 1-38, ABeta 1-40, and ABeta 1-42. ABeta fragments of different length produced by cleavage of amyloid precursor protein (APP) by beta-secretase (BACE) and gamma-secretase complex in brain and excreted into CSF. Participants were classified as asymptomatic at risk: cognitively and functionally normal (Clinical Dementia Rating Scale score [CDR] =0), but with biomarker pattern consistent with early stage AD (preclinical stage); and prodromal: had some limited cognitive impairment (CDR =0.5), and still functionally normal, with biomarker pattern consistent with early stage (predementia) AD, but had as of yet no dementia (predementia stage). Here, 'Number analyzed=0' signifies that either CSF concentration was below lower limit of quantification for assay or sample was collected under parent study 54861911ALZ2002 (NCT02260674).

  2. Double-blind Treatment Phase (Period 1): Percent Change From Baseline in Cerebrospinal Fluid (CSF) Soluble Amyloid Precursor Protein (sAPP) Fragments (sAPP-alpha and sAPP-beta) Levels [ Time Frame: Baseline, DB Day 1 and DB Week 52 ]
    The CSF samples were obtained for measuring levels of different soluble amyloid precursor protein (sAPP) fragments (sAPP-alpha, sAPP-beta). Participants were classified as asymptomatic at risk: cognitively and functionally normal (CDR score =0), but with biomarker pattern consistent with early stage alzheimer's disease (AD) (preclinical stage); and prodromal: had some limited cognitive impairment (CDR =0.5), and still functionally normal, with biomarker pattern consistent with early stage (predementia) AD, but had as of yet no dementia (predementia stage). Here, 'Number analyzed=0' signifies that either CSF concentration was below lower limit of quantification for assay or sample was collected under parent study 54861911ALZ2002 (NCT02260674).

  3. Double-blind Treatment Phase (Period 1): Percent Change From Baseline in Plasma Amyloid Beta (ABeta) (1-38, 1-40, 1-42) Levels [ Time Frame: Baseline, DB Day 1, DB Week 24, and DB Week 52 ]
    Plasma samples were obtained for measuring levels of different ABeta fragments such as ABeta 1-38, ABeta 1-40, ABeta 1-42. ABeta fragments of different length were produced by cleavage of APP by beta-secretase (BACE) and gamma-secretase complex in different peripheral tissues, including white blood cells and were measured in plasma. Participants classified as asymptomatic at risk: cognitively and functionally normal (CDR score =0), but with biomarker pattern consistent with early stage AD (preclinical stage); and prodromal: had some limited cognitive impairment (CDR =0.5), and still functionally normal, with biomarker pattern consistent with early stage (predementia) AD, but had as of yet no dementia (predementia stage). Here, 'Number analyzed=0' signifies that either CSF concentration was below lower limit of quantification for assay or sample was collected under parent study 54861911ALZ2002 (NCT02260674).

  4. Double-blind Treatment Phase (Period 1): Percent Change From Baseline in Cerebrospinal Fluid (CSF) Tau Protein and Phosphorylated Tau (p-Tau) Protein Level [ Time Frame: Baseline, DB Day 1 and DB Week 52 ]
    The CSF samples were obtained for measuring levels of Tau protein and phosphorylated (p)-tau protein. Participants were classified as asymptomatic at risk: cognitively and functionally normal (CDR score =0), but with biomarker pattern consistent with early stage AD (preclinical stage); and prodromal: had some limited cognitive impairment (CDR =0.5), and still functionally normal, with biomarker pattern consistent with early stage (predementia) AD, but had as of yet no dementia (predementia stage). Here, 'Number analyzed=0' signifies that either CSF concentration was below lower limit of quantification for assay or sample was collected under parent study 54861911ALZ2002 (NCT02260674).

Enrollment in this study should be completed (Day 1 of double-blind [DB] treatment phase) as soon as possible, but within 6 weeks, following completion of their treatment period under the parent protocol. If not defined under the parent protocol, completion of the treatment period is defined as having completed all study related procedures of the last visit of the treatment period under the parent protocol. A screening phase of up to 12 weeks may be allowed following written approval of the Sponsor

If possible, an alternate informant meeting these criteria who can replace the primary informant should be identified prior to randomization

Exclusion Criteria:

  • Any condition or situation which, in the opinion of the Investigator, may put the participant at significant risk, may confound the study results, or may interfere significantly with participant's participation in the study
  • The use of concomitant medications known to prolong the QT/QTc interval
  • Participant has a history of moderate or severe hepatic impairment or severe renal insufficiency unless completely resolved for more than a year.
