Primary Outcome Measures:
  • Incidence of subjects meeting toxicity or intolerable dose criteria [ Time Frame: Duration of the study ]
  • Incidence of treatment emergent adverse events (TEAEs) categorized by severity and causal relationship to study drug [ Time Frame: Duration of the study ]
  • Incidence of ocular TEAEs identified by ocular examination, and spontaneously reported, categorized by severity and causal relationship to study drug [ Time Frame: Duration of the study ]
  • Incidence of systemic TEAEs identified by physical examination, changes in vital signs, ECGs, clinical laboratory assessments, and spontaneously reported, categorized by severity and causal relationship to study drug [ Time Frame: Duration of the study ]
  • Incidence of positive anti-drug-antibodies (ADA) [ Time Frame: Duration of the study ]

Secondary Outcome Measures:
  • Plasma RN6G concentrations will be measured and used in the determination of pharmacokinetic parameters after the first and after the sixth dose [ Time Frame: Days 1, 2, 7, 14, 19, 28, 45, 56, 75, 84, 103, 112, 131, 140, 141, 154, 168, 224, 304 ]
  • Change from baseline (absolute and %) of plasma Aβ(1-x)(total), Aβ(1-40), and Aβ(1-42) concentrations [ Time Frame: Days 1, 2, 7, 14, 19, 28, 45, 56, 75, 84, 103, 112, 131, 140, 141, 154, 168, 224, 304 ]
  • Change from baseline in clinical laboratory assessments, vital signs, and ECGs [ Time Frame: Duration of the study ]
