Limitations and caveats
An independent assessment concluded the trial was not likely to meet the primary endpoint upon completion and therefore, trial stopped for futility.

ListOutcomeTime frameDescription
PrimaryChange From Baseline in Alzheimer´s Disease Assessment Scale- Cognitive Subscale (ADAS-Cog13) ScoreBaseline, Week 78
ADAS-Cog13 (13-item version of ADAS Cog) is a psychometric instrument that evaluates word recall, ability to follow commands, constructional praxis, naming, ideational praxis, orientation, word recognition, memory, comprehension of spoken language, word-finding, and language ability, with a measure of delayed word recall and concentration/ distractibility. The total score of the 13-item scale ranges from 0 to 85, with an increase in score indicating cognitive worsening. Least Squares (LS) mean was determined by mixed-model repeated measures (MMRM) model with factors for treatment, visit, treatment-by-visit interaction, acetylcholinesterase Inhibitor (AChEI) use at baseline, pooled site, and covariates for baseline ADAS-Cog13 total score, age at baseline, and baseline ADAS-Cog13 total score-by-visit interaction.
SecondaryChange From Baseline in Alzheimer´s Disease Cooperative Study Activities of Daily Living Inventory Instrumental Items Score (ADCS-iADL)Baseline, Week 78
The ADCS-ADL is a 23-item inventory developed as a rater-administered questionnaire answered by the participant's caregiver. The ADCS-ADL measures both basic and instrumental activities of daily living by participants. The range for the ADCS-iADL is 0-59 with higher scores reflecting better performance. LS Mean was determined by MMRM model with factors for treatment, visit, treatment-by-visit interaction, AChEI use at baseline, pooled site, and covariates for baseline iADL score, age at baseline, and baseline iADL score-by-visit interaction.
SecondaryChange From Baseline in Functional Activities Questionnaire (FAQ) ScoreBaseline, Week 78
FAQ is a 10-item, caregiver-based questionnaire and was administered to the study partner who was asked to rate the participant's ability to perform a variety of activities ranging from writing checks, assembling tax records, shopping, playing games, food preparation, traveling, keeping appointments, traveling out of neighborhood, keeping track of current events and understanding media. FAQ total score was calculated by adding the scores from each of the 10 items. Each activity is rated on a scale from 0 to 3 (Never did and would have difficulty now=1; never did \[the activity\] but could do now=0; normal=0; has difficulty but does by self=1; requires assistance=2; Dependent =3). FAQ scale is 0 to 30, with higher scores indicating greater impairment. LS Mean determined by MMRM model with factors for treatment, visit, treatment-by-visit interaction, AChEI use at baseline, pooled site, and covariates for baseline FAQ total score, by-visit interaction and age at baseline.
SecondaryChange From Baseline on the Integrated Alzheimer's Disease Rating Scale (iADRS) ScoreBaseline, Week 78
The iADRS is a composite that measures both cognition and function. The iADRS comprises scores form the ADAS- Cog and the ADCS-iADL. The iADRS is calculated as a linear combination of the total scores of the ADAS-Cog13 (score range 0 to 85 with higher scores reflecting worse performance) and the ADCS-iADL (score range from 0-59 with higher scores reflecting better performance). The iADRS score ranges from 0 to 144 with higher scores indicating greater impairment. LS Mean was determined by MMRM with factors for treatment, visit, treatment-by-visit interaction, AChEI use at baseline, pooled site, and covariates for baseline iADRS13 total score, age at baseline, and baseline iADRS13 total score-by-visit interaction.
SecondaryChange From Baseline in the Clinical Dementia Rating - Sum of Boxes (CDR-SB) ScoreBaseline, Week 78
The CDR-SB is a rater administered scale and impairment is scored in each of categories: memory, orientation, judgment and problem solving, community affairs, home and hobbies and personal care. Impairment is scored on a scale in which no dementia = 0, questionable dementia = 0.5, mild dementia = 1, moderate dementia = 2 and severe dementia = 3. The 6 individual category ratings, or "box scores", were added together to give the CDR-Sum of Boxes which ranges from 0-18, with higher scores indicating greater impairment. LS Mean was determined by MMRM methodology with factors for treatment, visit, treatment-by-visit interaction, AChEI use at baseline, pooled site, and covariates for baseline CDR-SB score, age at baseline, and baseline CDR-SB score-by-visit interaction.
SecondaryTime to Progression as Measured by Loss of Clinical Dementia Rating (CDR) Global Score StageFrom Loss of 1 Global Stage through Week 78
The CDR global score is a composite score calculated using the Washington University CDR-assignment algorithm applied to the 6 individual domain box scores (Morris 1993). The memory domain is considered the primary category that drives the CDR global outcome, and all other domains are secondary. The CDR global score ranges from 0 to 3 (0 = no dementia, 0.5 = questionable dementia, 1 = mild dementia, 2 = moderate dementia, 3 = severe dementia).
SecondaryChange From Baseline in Neuropsychiatric Inventory (NPI) ScoreBaseline, Week 78
The NPI is a questionnaire administered to caregivers that quantifies behavioral changes. Each of the 12 behavioral domains the caregiver reports as present are scored for Frequency, scale: 1 (Occasionally) to 4 (Very Frequently), and Severity, scale: 1 (Mild) to 3 (Severe). If the domain is reported by the caregiver as 'Not Affected,' that domain is scored as 0. The individual domain scores are calculated by multiplying the frequency times the severity for each domain. NPI Total Score is calculated by adding the individual domain scores together for all 12 domains, with a scores range from 0 to 144, with higher scores indicating a greater severity of neuropsychiatric disturbance. LS Mean was determined by MMRM methodology with factors for treatment, visit, treatment-by-visit interaction, AChEI use at baseline, pooled site, and covariates for baseline NPI score, age at baseline, and baseline NPI score-by-visit interaction.
SecondaryChange From Baseline on the Mini-Mental State Examination (MMSE)Baseline, Week 78
The MMSE is an instrument used to assess a participant's global cognitive function. The MMSE assesses orientation to time and place, immediate and delayed recall of words, attention and calculation, language (naming, comprehension and repetition), and spatial ability (copying a figure). The range for MMSE total Score is 0 to 30, with a higher score indicating better cognitive performance. LS Mean was determined by MMRM methodology with factors for treatment, visit, treatment-by-visit interaction, AChEI use at baseline, pooled site, and covariates for baseline MMSE total score, age at baseline, and baseline MMSE total score-by-visit interaction.
SecondaryPercent Change From Baseline in Concentration of Cerebrospinal Fluid (CSF) Biomarker Amyloid Beta (Aβ)1-42Baseline, Week 71
Concentration of the peptide Aβ 1-42 in plasma measured by validated immunoassay. LS Mean was determined by Analysis of covariance (ANCOVA) with last observation carried forward (LOCF), terms for treatment, baseline biomarker and age at baseline.
SecondaryPercent Change From Baseline in Concentration of CSF Biomarker Aβ1-40Baseline, Week 71
Concentration of the peptide Aβ 1-40 in plasma measured by immunoassay. LS Mean was determined by ANCOVA with LOCF (last observation carried forward), terms for treatment, baseline biomarker and age at baseline.
