Further study details as provided by GlaxoSmithKline:

Primary Outcome Measures:
  • The temporal changes of amyloid beta levels in CSF after GSK933776 single dose administration in the patients with Alzheimer's disease and Mild Cognitive impairment [ Time Frame: 22 hours ]
    To compare the changes of amyloid beta levels between the baseline (9 hours) and after single dose of GSK933776 iv administration of 13 hours


Secondary Outcome Measures:
  • The temporal changes of total and free amyloid beta levels in plasma after GSK933776 single dose administration in the patients with Alzheimer's disease and Mild Cognitive impairment [ Time Frame: Two months ]
  • The temporal changes of Tau and phosphor Tau - 181 levels in CSF after GSK933776 single dose administration in the patients with Alzheimer's disease and Mild Cognitive impairment [ Time Frame: 22 hours ]
  • Estimated pharmacokinetic parameters of AUC, Cmax and Tmax in CSF and plasma at multiple time points with various intervals. [ Time Frame: three months ]
  • To assess the safety and tolerability after single dose of GSK933776 administration. [ Time Frame: three months ]
    The safety and tolerability measures are performed at screening, dosing day and follow up. The assessments included: • Adverse event reporting and safety laboratory data. • CNS Safety: MRI and MMSE. • CVS safety: ECG and vital signs. •Anti-GSK933776 antibodies.

Detailed Description:
This is a phase I, an open label, single dose and parallel group study to assess short term pharmacodynamics and safety of GSK933776. The effect on the beta amyloid levels will be assessed in early (MCI) and mild Alzheimer's disease (AD) patients after a single dose of GSK933776 by i.v. administration.
