Clinical Dementia Rating Scale - Sum of Boxes (CDR-SB) Score
The CDR-SB is a numeric scale used to quantify the severity of symptoms of dementia. A qualified health professional assesses a participant's cognitive and functional performance in 6 areas: memory, orientation, judgment and problem solving, community affairs, home and hobbies, and personal care. The CDR scale gives a score from 0 to 3 for each of the 6 areas, with a lower value being desirable. The sum of these 6 areas, the CDR-SB score, can range from 0 to 18, with a lower value being desirable.

Number of Participants With Treatment Emergent Adverse Events (TEAEs) ^[2]

End point description

A TEAE was defined as an adverse event (AE) that began on or after the first study drug dose date and no more than 20 weeks after the last dose of study drug. An adverse event (AE) was defined as any untoward medical occurrence which does not necessarily have a causal relationship with this treatment. Serious AEs (SAEs) were defined as an event that results in death, is life-threatening, results in hospitalization or prolongs hospitalization, is a congenital abnormality, results in persistent or significant disability/incapacity, or is an important medical event. Events were rated in severity as mild, moderate, or severe, and were categorized as having a reasonable possibility or no reasonable possibility of relationship to study drug. Safety Dataset: participants who received at least 1 dose of study drug.

Change From Baseline Over Time in ADAS-Cog-14 Constructional Praxis Score

End point description

The ADAS-Cog was designed to assess the cognitive impairments most common in AD. The ADAS-Cog-14 includes the original 11 items from the ADAS-Cog-11 [1. Spoken language ability, 2. Comprehension of spoken language, 3. Recall of test instructions, 4. Word-findings difficulty in spontaneous speech, 5. Following commands, 6. Naming objects and fingers, 7. Constructional praxis, 8. Ideational praxis, 9. Orientation, 10. Word-recall task, 11. Word recognition task] and includes 3 additional tasks [12. Number cancellation task, 13. Delayed word recall task, 14. Executive functioning], for increased sensitivity in MCI patients. The Constructional Praxis Score of the ADAS-Cog-14 ranges from 0 to 5, with a higher score representing greater impairment. Intent-to-Treat Data Set: all randomized participants who received at least 1 dose of study drug. n=Participants with an assessment at given time point.

Change From Baseline Over Time in ADAS-Cog-14 Word Find Difficulty Spontaneous Speech Score

End point description

The ADAS-Cog was designed to assess the cognitive impairments most common in AD. The ADAS-Cog-14 includes the original 11 items from the ADAS-Cog-11 [1. Spoken language ability, 2. Comprehension of spoken language, 3. Recall of test instructions, 4. Word-findings difficulty in spontaneous speech, 5. Following commands, 6. Naming objects and fingers, 7. Constructional praxis, 8. Ideational praxis, 9. Orientation, 10. Word-recall task, 11. Word recognition task] and includes 3 additional tasks [12. Number cancellation task, 13. Delayed word recall task, 14. Executive functioning], for increased sensitivity in MCI patients. The Word Find Difficulty Spontaneous Speech Score of the ADAS-Cog-14 ranges from 0 to 5, with a higher score representing greater impairment. Intent-to-Treat Data Set: all randomized participants who received at least 1 dose of study drug. Participants with an assessment at given time point.

Change From Baseline Over Time in Functional Activities Questionnaire (FAQ) Score

End point description

FAQ measures level of assistance (functional disability) needed for carrying out instrumental activities in daily living (iADLs). FAQ score ranges from 0-30 and consists of 10 items (each scored from 0-3), which measure a specific iADL in the past 4 weeks: [1) writing checks, paying bills, keeping financial records; 2) assembling tax or business records; 3) shopping alone; 4) playing a game of skill; 5) making coffee or tea; 6) preparing a balanced meal; 7) keeping track of current events; 8) attending to and understanding a television program, book, or magazine; 9) remembering appointments, family occasions, medications; 10) traveling out of the neighborhood]. Performance in each category is rated from 0-3: 0=normal; 1=has difficulty, but does by self; 2=requires assistance; or 3=dependent. The FAQ was administered by a trained interviewer. Higher scores indicate a greater requirement of assistance. Intent-to-Treat Data Set. n=Participants with an assessment at given time point.

Change From Baseline Over Time in 24-Item Alzheimer's Disease Cooperative Study/Activities of Daily Living Scale Adapted for Patients With Mild Cognitive Impairment (ADCS-MCI-ADL-24) Total Score

End point description

The ADCS-MCI-ADL-24 is a 24-item, study partner-based assessment of activities of daily living designed specifically for AD patients and is completed by a trained rater. The scale assesses functional activities such as cooking, household chores, shopping, keeping appointments, social interactions and hobbies. Items are assessed according to whether they were performed in the past 4 weeks and, if so, some items are further assessed as to whether they were performed independently, with supervision, or with physical help. Scores on the ADCS-ADL-MCI range from 0 to 69, where higher score indicates greater capability to carry out activities of daily living. Intent-to-Treat Data Set: all randomized participants who received at least 1 dose of study drug. n=Participants with an assessment at baseline and given time point.

The RBANS is a 25-minute, standardized neurocognitive battery with North American population-based normative data. The RBANS measures five neurocognitive domains, with age-based scaling. Twelve subtests measure cognitive decline or improvement across the following domains: 1. Immediate Memory – List Learning and Story Memory, 2. Visuospatial/Constructional – Figure Copy and Line Orientation, 3. Language – Picture naming and Semantic Fluency, 4. Attention – Digit Span and Coding, and 5. Delayed Memory – List Recall, List Recognition, Story Memory, and Figure Recall. Total score can range from 40 to 160 with a higher score representing a better outcome.

Change From Baseline Over Time in Neuropsychiatry Inventory (NPI) Total Score

End point description

The NPI is used to assess changes in the participant's behavior that occurred in a defined period of time (4 weeks). The NPI assesses 12 behavioral domains on the dimensions of frequency and severity. Frequency is rated on a scale where 0 = absent, 1 = occasionally, 2 = often, 3 = frequently, 4 = very frequently. Severity is rated on a scale where 0 = absent, 1 = mild, 2 = moderate, 3 = severe. For each of the domains, 3 scores are obtained: frequency, severity, and total (product of frequency and severity; ranges from 0 to 12, with a lower score desirable). A total NPI score can be calculated by summing the domain total scores. Total Score ranges from 0 to 144 with a lower score desirable. Intent-to-Treat Data Set: all randomized participants who received at least 1 dose of study drug. n=Participants with an assessment at given time point.
