Misura Descrizione
Lasso di tempo
Number of Participants With Treatment-Emergent Adverse Events (AEs) or Serious Adverse Events (SAEs)
Lasso di tempo: Day 1 up to 6 months after last dose of study medication, assessed up to Month 24
An AE was any untoward medical occurrence in a participant who received study medication without regard to possibility of causal relationship. SAE: an AE resulting in any of following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent AEs are events between first dose of study medication and up to 6 months after last dose that were absent before treatment or worsened relative to pre-treatment state.
Day 1 up to 6 months after last dose of study medication, assessed up to Month 24
Number of Participants With Change From Baseline in Brain Magnetic Resonance Imaging (MRI) Abnormalities
Lasso di tempo: Baseline up to Month 24

Lasso di tempo
Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-cog) Score at Baseline
Lasso di tempo: Baseline
ADAS-cog is a structured scale assessing the severity of cognitive impairment in Alzheimer's Disease. It comprised of following 11 items (range): word recall (0-10), naming objects and fingers (0-5), following commands (0-5), constructional praxis (0-5), ideational praxis (0-5), orientation (0-8), word recognition (0-12), recall of test instructions (0-5), spoken language ability (0-5), word-finding difficulty (0-5), comprehension of spoken language (0-5). ADAS-cog total score was calculated as the sum of scores for the 11 items and ranged from 0 to 70. Higher total and individual item scores indicate greater cognitive impairment. Baseline was defined as the last assessment prior to the first study drug infusion.

Disability Assessment for Dementia (DAD) Score at Baseline
Lasso di tempo: Baseline
DAD is a functional assessment based on interview with the caregiver. It consisted of 40 items, 17 related to self-care and 23 items involving instrumental activities of daily living. Each item was scored as yes = 1, no = 0 and not applicable= N/A. A total score was obtained by adding the rating for each question and converting this to a total score out of 100. The items rated N/A were not considered for the total score. DAD total score ranged from 0 to 100, with higher scores indicating better functioning. Baseline was defined as the last assessment prior to the first study drug infusion.
