Outcome

Type Measure Description Time frame Safety issue
Primary Change From Baseline in Alzheimer´s Disease Assessment Scale- Cognitive Subscale (ADAS-Cog13) Score 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. Baseline, Week 78
Secondary Change From Baseline in Alzheimer´s Disease Cooperative Study Activities of Daily Living Inventory Instrumental Items Score (ADCS-iADL) 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. Baseline, Week 78
Secondary Change From Baseline in Functional Activities Questionnaire (FAQ) Score 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. Baseline, Week 78
Secondary Change From Baseline on the Integrated Alzheimer's Disease Rating Scale (iADRS) Score 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. Baseline, Week 78
Secondary Change From Baseline in the Clinical Dementia Rating - Sum of Boxes (CDR-SB) Score 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. Baseline, Week 78
Secondary Time to Progression as Measured by Loss of Clinical Dementia Rating (CDR) Global Score Stage 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). From Loss of 1 Global Stage through Week 78
Secondary Change From Baseline in Neuropsychiatric Inventory (NPI) Score 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. Baseline, Week 78
Secondary Change From Baseline on the Mini-Mental State Examination (MMSE) 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. Baseline, Week 78
Secondary Percent Change From Baseline in Concentration of Cerebrospinal Fluid (CSF) Biomarker Amyloid Beta (Aß)1-42 Concentration of the peptide Aß 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. Baseline, Week 71
Secondary Percent Change From Baseline in Concentration of CSF Biomarker Aß1-40 Concentration of the peptide Aß 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. Baseline, Week 71
Secondary Change From Baseline in CSF Biomarker Total Tau Cerebrospinal fluid samples were collected for analysis of concentration total tau. LS Mean was determined by ANCOVA with LOCF and with factors for treatment, baseline biomarker and age at baseline. Baseline, Week 71
Secondary Change From Baseline in CSF Biomarker Phosphorylated Tau Cerebrospinal fluid samples are collected for analysis of concentration of phosphorylated tau. LS Mean was determined by ANCOVA with LOCF and with factors for treatment, baseline biomarker and age at baseline. Baseline, Week 71
Secondary Change From Baseline in Brain Amyloid Burden Using Florbetapir Amyloid Positron Emission Tomography (PET) Scan Amyloid deposition in the brain is one of the defining neuropathologic findings of Alzheimer's disease. Florbetapir exhibits high affinity specific binding to amyloid plaques. The change from baseline was measured as average standard uptake value ratio (SUVr) in prespecified regions of interest (ROI) assessed by florbetapir amyloid PET imaging in a subset of participants. The Centiloid scale standardizes quantitative brain amyloid PET results to allow cross-tracer and cross-methodology comparisons. The Centiloid scale anchor points are 0 and 100, where 0 represents a high-certainty amyloid negative scan and 100 represents the amount of global amyloid deposition found in a typical AD scans. Florbetapir SUVr was converted to the Centiloid scale using the following conversion: Florbetapir Centiloids = 183 x SUVr - 177. LS Mean was determined by using ANCOVA methodology with terms for treatment, baseline biomarker and age at baseline. Baseline, Week 78
Secondary Change From Baseline in Regional Cerebral Blood Flow (rCBF) Using Florbetapir Perfusion Scan Florbetapir perfusion evaluated the regional cerebral blood flow (rCBF) as a biomarker of brain function and was performed at the same time as the amyloid florbetapir PET. Cerebral perfusion, especially in temporal and parietal areas, is reduced in AD and this pattern of hypoperfusion closely mirrors the hypometabolism pattern observed using FDG PET. Annualized change is derived as change at LOCF divided by (LOCF date - baseline date) multiplied by 365. LS Mean was determined by ANCOVA with LOCF (last observation carried forward) and with factors for treatment, baseline biomarker and age at baseline. Baseline, Week 78
Secondary Change From Baseline in Whole Brain Volume Magnetic resonance imaging (MRI) was used to evaluate the effect of lanabecestat on brain atrophy/whole brain volumes. Annualized change is derived as change at LOCF divided by (LOCF date - baseline date) multiplied by 365. LS Mean was determined by ANCOVA with LOCF and with factors for treatment, baseline volumetric magnetic resonance imaging (vMRI), intracranial volume and age at baseline. Baseline, Week 78
Secondary Population Pharmacokinetics (PK): Apparent Oral Clearance of Lanabecestat The apparent oral clearance of lanabecestat was estimated using a population approach. No covariate effects were assessed as part of this analysis. Predose, Week 4, 7, 19, 39, 45 and Week 71 post dose
Secondary Population PK: Central Volume of Distribution of Lanabecestat The central volume of distribution for lanabecestat was estimated using a population approach. No covariate effects were assessed as part of this analysis. Predose, Week 4, 7, 19, 39, 45 and week 71 post dose
