Current Primary Outcome Measures  ICMJE
 (submitted: December 22, 2015)
Incidence of Adverse Events (TEAEs) [ Time Frame: 4 weeks ]
For all AE summaries, if a patient had more than one AE within a preferred term, the patient was counted only once, at the maximum severity and with the closest relationship to study drug. If a patient had more than one AE within a SOC, the subject was similarly counted only once when reporting results for that SOC.
Original Primary Outcome Measures  ICMJE
 (submitted: February 12, 2013)
  • Incidence of treatment-emergent adverse events (TEAEs), [ Time Frame: 4 weeks ]
  • Changes from Baseline in neurological examinations [ Time Frame: 4 weeks ]

Current Secondary Outcome Measures  ICMJE Not Provided
Original Secondary Outcome Measures  ICMJE
 (submitted: February 12, 2013)
  • Plasma ELND005 concentrations [ Time Frame: 4 Weeks ]
    ELND005 PK profile to optimize PK model including patient population
  • Changes from baseline in vital signs [ Time Frame: 4 weeks ]
Current Other Pre-specified Outcome Measures
 (submitted: December 22, 2015)
  • Changes From Baseline in Abnormal Neurological Examination Results [ Time Frame: Baseline and 4 weeks ]
    Subjects with Abnormal Neurological Examination Results
  • Pharmacokinetic Assessment [ Time Frame: Baseline and 4 Weeks ]
    Mean Plasma ELND005 Concentrations- Cmax
  • Cognitive Outcome (RADD Total Score) [ Time Frame: Baseline and 4 Weeks ]
    Rapid Assessment for Development Disabilities (RADD) The RADD test was developed from the low-difficulty items from published intelligence tests (Walsh et al 2007). It was specifically developed for evaluation of individuals with intellectual disabilities and developmental disabilities. It is a validated and reliable cognitive screening instrument that can be rapidly administered. The RADD is composed of 76 items. Each item is scored as 0 (incorrect) or 1 (correct).The test assesses a wide range of functional abilities including receptive and expressive language, orientation, registration, recall, attention, self identification, motor skills, imitation, abstract reasoning, number skills, comprehension and short-term memory to give a total score. Scores are from 0 to 76. A higher total score is correlated with a higher Cognitive Impairment level.
  • Improvement in NPI Total Scores in Subjects With NPI Score ≥1 at Baseline Baseline [ Time Frame: Baseline and 4 weeks ]
    The Neuropsychiatric Inventory(NPI) (Cummings et al 1994) is a behavioral measure that assesses psychopathology in dementia patients. The NPI was administered at the Baseline Visit (Day 1) and at Day 28 (EOS) or ET. A decrease in score shows an improvement in symptoms.
