Primary Outcome Measures:
  • Number of Participants with Adverse Events [ Time Frame: Up to Week 24 ] [ Designated as safety issue: Yes ]
    An Adverse Event (AE) is any untoward medical occurrence in a participant administered an investigational product. An AE does not necessarily have a causal relationship with the medicinal product. The investigator or sub-investigator reviews all laboratory findings and determines if they constitute an AE. In-patient observation assessments will be performed during 1 week post-dose, followed by the out-patient observation assessments in groups: 0.0006, 0.006, 0.04, 0.2 mg/kg up to the end of Week 8 and in groups: 1, 3, 6, 10 kg/mg) up to the end of Week 24.


Secondary Outcome Measures:
  • Maximum Observed Plasma Concentration (Cmax) [ Time Frame: Up to 24 Weeks post-dose ] [ Designated as safety issue: No ]
  • Time to Reach Maximum Observed Plasma Concentration (Tmax) [ Time Frame: Up to 24 Weeks post-dose ] [ Designated as safety issue: No ]
  • Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-t)] [ Time Frame: Up to 24 Weeks post-dose ] [ Designated as safety issue: No ]
    AUC (0-t)= Area under the plasma concentration versus time curve from time zero (pre-dose) to time of last quantifiable concentration (0-t).

  • Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - infinity)] [ Time Frame: Up to 24 Weeks post-dose ] [ Designated as safety issue: No ]
    AUC (0 - infinity)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - infinity). It is obtained from AUC (0 - t) plus AUC (t - infinity).

  • Plasma Decay Half-Life (t1/2) [ Time Frame: Up to 24 Weeks post-dose ] [ Designated as safety issue: No ]
    Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

  • Pharmacokinetic Parameter: Volume of Distribution (Vd) [ Time Frame: Up to 24 Weeks post-dose ] [ Designated as safety issue: No ]
  • Pharmacokinetic Parameter: Clearance (CL) [ Time Frame: Up to 24 Weeks post-dose ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: E6011 Drug: E6011
A single ascending dose (SAD) administration of E6011 is administered to 8 groups as a 30-minute intravenous infusion at a dose of either 0.0006, 0.006, 0.04, 0.2, 1, 3, 6, or 10 mg/kg. Each participant in each group will receive a single-dose only once. The study drug will not be administered to more than two participants on the same day, and the second participant must start the study treatment after at least a 2-hour interval from the start of the study treatment in the first participant. The subsequent ascending dose groups will start approximately at least every 3 weeks following the study treatment in the first participant of each group.
Placebo Comparator: E6011 Matching Placebo Drug: E6011 Matching Placebo
A SAD administration of E6011 Matching Placebo is administered to 2 participants in each of 8 groups as a 30-minute intravenous infusion at a placebo dose of either 0.0006, 0.006, 0.04, 0.2, 1, 3, 6, or 10 mg/kg. Each participant in each group will receive a single-dose only once. The study drug will not be administered to more than two participants on the same day, and the second participant must start the study treatment after at least a 2-hour interval from the start of the study treatment in the first participant. The subsequent ascending E6011 Matching Placebo dose groups will start approximately at least every 3 weeks following the study treatment in the first participant of each group.
