Current Primary Outcome Measures  ICMJE
 (submitted: December 13, 2017)
  • Single Ascending Dose (SAD) (Part 1): Number of Subjects With Adverse Events as a Measure of Safety and Tolerability of JNJ-63733657 [ Time Frame: Up to Day 106 ]
    An adverse event is any untoward medical event that occurs in a subject administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.
  • Multiple Ascending Dose (MAD) (Part 2): Number of Subjects With Adverse Events as a Measure of Safety and Tolerability of JNJ-63733657 [ Time Frame: Up to Day 162 ]
    An adverse event is any untoward medical event that occurs in a subject administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.

Current Secondary Outcome Measures  ICMJE
 (submitted: December 13, 2017)
  • SAD (Part 1) and MAD (Part 2): Maximum Observed Serum Concentration (Cmax) of JNJ-63733657 [ Time Frame: Up to Day 106 (SAD) and up to Day 162 (MAD) ]
    The Cmax is the maximum observed serum concentration of drug JNJ-63733657.
  • SAD (Part 1) and MAD (Part 2): Time to Reach Maximum Observed Serum Concentration (Tmax) of JNJ-63733657 [ Time Frame: Up to Day 106 (SAD) and up to Day 162 (MAD) ]
    Tmax is defined as time to reach the maximum observed serum JNJ-63733657 concentration.
  • SAD (Part 1) and MAD (Part 2): Area Under the Serum Concentration-time Curve From Time Zero to Time of the Last Observed Quantifiable Concentration (AUC [0-Last]) of JNJ-63733657 [ Time Frame: Up to Day 106 (SAD) and up to Day 162 (MAD) ]
    AUC (0-last) is defined as area under the serum JNJ-63733657 concentration-time curve from time 0 to time of the last observed quantifiable concentration.
  • SAD (Part 1) and MAD (Part 2): Area Under the Serum Concentration-Time Curve From Time Zero to Infinite Time (AUC [0-infinity]) of JNJ-63733657 [ Time Frame: Up to Day 106 (SAD) and up to Day 162 (MAD) ]
    AUC (0-infinity) is defined as area under the serum JNJ-63733657 concentration-time curve from time 0 to infinite time.
  • MAD (Part 2): Area Under the Serum JNJ-63733657 Concentration-time Curve During a Dosing Interval (t) (AUC tau) [ Time Frame: Up to Day 85 (MAD) ]
    AUC tau is defined as area under the serum JNJ-63733657 concentration-time curve during a dosing interval (tau).
  • MAD (Part 2): Accumulation Ratio (R) [ Time Frame: Up to Day 162 (MAD) ]
    R is obtained by dividing AUC of JNJ-63733657 at two different time points.
  • SAD (Part 1) and MAD (Part 2): Total Systemic Clearance (CL) of JNJ-63733657 [ Time Frame: Up to Day 106 (SAD) and up to Day 162 (MAD) ]
    CL is a quantitative measure of the rate at which JNJ-63733657 is removed from the body. The total systemic clearance after intravenous dose is estimated by dividing the total administered dose by the plasma Area Under the Serum Concentration-Time Curve From Time Zero to Infinite Time (AUC[0-infinity]).
  • SAD (Part 1) and MAD (Part 2): Volume of Distribution at Steady-State (Vss) of JNJ-63733657 [ Time Frame: Up to Day 106 (SAD) and up to Day 162 (MAD) ]
    Vss is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug. Steady state Vss is the apparent volume of distribution at steady-state which is estimated by (D/AUC[0-infinity])*(AUMC[0-infinity])/AUC[0-infinity]) where D is the dose of study drug, AUMC(0-infinity) is the area under the first moment curve extrapolated to infinity and AUC(0-infinity) is the area under the serum concentration-time curve from time zero to infinite time.
  • SAD (Part 1) and MAD (Part 2): Terminal Half-Life(t[1/2]) of JNJ-63733657 [ Time Frame: Up to Day 106 (SAD) and up to Day 162 (MAD) ]
    t(1/2) is associated with the terminal slope (lambda [z]) of the semi-logarithmic drug concentration-time curve, calculated as 0.693/lambda(z).
  • SAD (Part 1) and MAD (Part 2): JNJ-63733657 Concentration in Cerebrospinal Fluid (CSF) [ Time Frame: Up to Day 57 (SAD) and up to Day 148 (MAD) ]
    CSF concentration assessment will be done to characterize the pharmacokinetics (PK) to estimate CSF concentration of JNJ-63733657.
  • SAD (Part 1) and MAD (Part 2): Number of Subjects With Anti-JNJ-6373365 Antibodies as a Measure of Immunogenicity [ Time Frame: Up to Day 106 (SAD) and up to Day 162 (MAD) ]
    Number of subjects with Anti-JNJ-63733657 antibodies will be evaluated in serum samples and potential CSF samples.
  • SAD (Part 1) and MAD (Part 2): Percent Change From Baseline in Total, Free, and Bound tau Biomarker Fragments in CSF [ Time Frame: Up to Day 106 (SAD) and up to Day 162 (MAD) ]
    Percent change from baseline in total, free, and bound tau (phosphorylation site) biomarker fragments in CSF will be evaluated to assess the effect of JNJ-63733657.

Official Title  ICMJE A 2-Part Randomized, Placebo-Controlled, Double-Blind, Single and Multiple Ascending Dose Study to Investigate Safety and Tolerability, Pharmacokinetics and Pharmacodynamics of JNJ-63733657 in Healthy Subjects and Subjects With Alzheimer's Disease
Brief Summary The purpose of this study is to assess the safety and tolerability of JNJ-63733657 following single ascending intravenous (IV) dose administration in healthy subjects (Part 1) and multiple ascending IV dose administrations in subjects with prodromal or mild Alzheimer's disease (AD) (Part 2).
Detailed Description Not Provided
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 1
Study Design  ICMJE Allocation: Randomized
Intervention Model: Sequential Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Condition  ICMJE Alzheimer Disease
Intervention  ICMJE
  • Drug: JNJ-63733657
    Subjects will receive single (Part 1) or multiple (Part 2) ascending dose levels of JNJ-63733657 intravenously.
  • Drug: Placebo
    Subjects will receive matching placebo intravenously.
Study Arms  ICMJE
  • Experimental: SAD (Part 1): Healthy Subjects
    In Part 1, single ascending intravenous (IV) doses of JNJ-63733657 or placebo will be administered to sequential cohorts (Cohorts 1 to 5) of healthy subjects on Day 1. The progression to the next (higher) dose level is dependent on acceptable safety and tolerability profile of JNJ-63733657 obtained after dose administration of the current dose level. Here, SAD indicates single ascending dose.
    Interventions:
    • Drug: JNJ-63733657
    • Drug: Placebo
  • Experimental: MAD (Part 2): Subjects With Alzheimer's Disease (AD)
    In Part 2, multiple ascending IV doses of JNJ-63733657 or placebo will be evaluated at three dose levels in sequential cohorts in subjects with prodromal or mild AD; 3 doses will be administered over a period of 8 weeks (Day 1, Day 29, Day 57). The starting dose will be decided based on the data from Part 1. Escalations will be done based on safety and tolerability similar to Part 1. Doses will not exceed those tested in Part 1. Here, MAD indicates multiple ascending dose.
    Interventions:
    • Drug: JNJ-63733657
    • Drug: Placebo
