Primary Outcome Measures:
  • Safety assessments: based on frequency of Serious Adverse Events (SAEs), frequency of Adverse events (AEs), discontinuation due to AEs and dose reduction [ Time Frame: Within the first 70 day after first dose ] [ Designated as safety issue: Yes ]
  • Biomarker Measures: CSF levels of Tau N-terminal domain fragments [ Time Frame: Within the first 70 day after first dose ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Effects of BMS-241027 on CSF levels of the mid-domain Tau fragment [ Time Frame: Within the first 70 days after first dose ] [ Designated as safety issue: No ]
  • Effects of BMS-241027 on cognitive performance using computerized cognitive tests [ Time Frame: Weeks 3, 6 and 9 ] [ Designated as safety issue: No ]
  • Effects of BMS-241027 on connectivity MRI [ Time Frame: Within the first 70 days after first dose ] [ Designated as safety issue: No ]
  • Maximal observed plasma concentration (Cmax) of BMS-241027 in subjects with mild Alzheimer's disease [ Time Frame: Weeks 1, 4, and 9 ] [ Designated as safety issue: No ]
    Intensive pharmacokinetic parameter Cmax will be derived from subgroups of subjects at Week 7

  • Observed plasma concentration at 24 hours post dose (C24) of BMS-241027 in subjects with mild Alzheimer's disease [ Time Frame: Weeks 1, 4, and 9 ] [ Designated as safety issue: No ]
    Intensive pharmacokinetic parameter C24 will be derived from subgroups of subjects at Week 7

  • Time of maximal observed plasma concentration (Tmax) of BMS-241027 in subjects with mild Alzheimer's disease [ Time Frame: Weeks 1, 4, and 9 ] [ Designated as safety issue: No ]
    Intensive pharmacokinetic parameter Tmax will be derived from subgroups of subjects at Week 7

  • Area under the concentration-time curve in one dosing interval [AUC(TAU)] of BMS-241027 in subjects with mild Alzheimer's disease [ Time Frame: Weeks 1, 4, and 9 ] [ Designated as safety issue: No ]
    Intensive pharmacokinetic parameter AUC(TAU) will be derived from subgroups of subjects at Week 7

  • Safety assessments: based on vital sign measurements, ECGs and clinical laboratory tests [ Time Frame: Within the first 70 day after first dose ] [ Designated as safety issue: Yes ]
  • Effects of BMS-241027 on CSF levels of neurofilaments [ Time Frame: Within the first 70 days after first dose ] [ Designated as safety issue: No ]
