Improve memory and language


Improves and maintains cognition above baseline9

*SIB=Severe Impairment Battery. Evaluates cognitive performance in moderate to severe AD. It is a 40-item scale that is scored from 9 (greatest impairment) to 100.9

Results from a randomized, multicenter, double-blind, parallel-group, placebo-controlled US study investigating the efficacy of NAMENDA plus donepezil in patients with moderate to severe AD. Results shown are from OC analysis. The study involved 404 outpatients ≥50 years of age with an MMSE score of ≥5 to ≤14 points. Patients were randomized to treatment with NAMENDA (10 mg BID) or placebo added to a stable regimen of donepezil† (5 mg-10 mg/day) for 24 weeks. At week 24, 322 patients (172 NAMENDA, 150 placebo) completed the study.9

†Donepezil therapy could have been 6 months or longer prior to study entry.9


Significant benefits in functional communication and language4,9,11


Post hoc results from a randomized, multicenter, double-blind, placebo-controlled US study investigating the efficacy of NAMENDA plus donepezil in patients with moderate to severe AD. Results shown are from OC analysis. Language items from the SIB were consolidated into 3 subscales based on linguistic parameters. Items assessing functional communication from the ADCS-ADL19 and BGP were consolidated into one functional communication score. The study involved 404 outpatients >50 years of age with an MMSE score of ≥5 to ≤14 points. Patients were randomized to treatment with NAMENDA (10 mg BID) or placebo added to a stable regimen of donepezil (5 mg-10 mg/day) for 24 weeks. At week 24, 322 patients (172 NAMENDA, 150 placebo) completed the study.4,9


Enhancing patients' abilities to communicate socially and interact with others may increase connectedness with family members

§ADCS-ADL =Alzheimer's Disease Cooperative Study Activities of Daily Living Inventory. A comprehensive battery of 19 ADL items aimed at measuring the functional ability of patients with moderate to severe AD. ADCS-ADL14 item responses range from total independence to total disability.15

||BGP=Behavioral Rating Scale for Geriatric Patients. A 35-item, observer-rated scale for the assessment of functional and behavioral disturbances of geriatric patients. The care dependence subscale includes 23 items13,16


Proven efficacy in day-to-day function


Significant functional benefits in combination9

Results from a randomized, multicenter, double-blind, parallel-group, placebo-controlled US study investigating the efficacy of NAMENDA plus donepezil in patients with moderate to severe AD. Results shown are from OC analysis. The study involved 404 outpatients ≥50 years of age with an MMSE score of ≥5 to ≤14 points. Patients were randomized to treatment with NAMENDA (10 mg BID) or placebo added to a stable regimen of donepezil (5 mg-10 mg/day) for 24 weeks. At week 24, 322 patients (172 NAMENDA, 150 placebo) completed the study.9


Efficacy in key activities of daily living4,17

*Alzheimer's Disease Cooperative Study Activities of Daily Living19 (ADCS-ADL19) Inventory: A comprehensive battery of 19 ADL items aimed at measuring the functional ability of patients with moderate to severe AD. ADCS-ADL19 item responses range from total independence to total disability.15

Results from a randomized, multicenter, double-blind, parallel-group, placebo-controlled US study investigating the efficacy of NAMENDA plus donepezil in patients with moderate to severe AD. Results shown are from OC analysis. ADLs were consolidated into 4 subscales based on a factor analysis. The study involved 404 outpatients ≥50 years of age with an MMSE score of ≥5 to ≤14 points. Patients were randomized to treatment with NAMENDA (10 mg BID) or placebo added to a stable regimen of donepezil (5 mg-10 mg/day) for 24 weeks. At week 24, 322 patients (172 NAMENDA, 150 placebo) completed the study.4,9,17


Improve and delay behavioral symptoms


Delaying symptoms of agitation, irritability, and nighttime behavior can help make life more manageable for patients and their families


Improve symptoms


Significantly improves behavior9,18

Results of a randomized, multicenter, double-blind, parallel-group, placebo-controlled US study investigating the efficacy of NAMENDA in 404 patients with moderate to severe AD. Results shown are from OC analysis. Patients were ≥50 years of age with an MMSE score of ≥5 to ≤14 points. Patients were randomized to treatment with NAMENDA (10 mg BID) or placebo added to a stable regimen of donepezil (5 mg-10 mg/day) for 24 weeks. At week 24, 322 patients (172 NAMENDA, 150 placebo) completed the study.9,18

Caregivers report benefits in behavior4,9,18


Delay onset of symptoms


Delays onset of behavioral symptoms in asymptomatic patients9,18

Results of a randomized, multicenter, double-blind, parallel-group, placebo-controlled US study investigating the efficacy of NAMENDA in 404 patients with moderate to severe AD. Results shown are from last observation carried forward (LOCF) analysis. Patients were ≥50 years of age with an MMSE score of ≥5 to ≤14 points. Patients were randomized to treatment with NAMENDA (10 mg BID) or placebo added to a stable regimen of donepezil (5 mg-10 mg/day) for 24 weeks. At week 24, 322 patients (172 NAMENDA, 150 placebo) completed the study.9,18

*NPI=Neuropsychiatric Inventory. The NPI is designed to assess behavioral disturbances occurring in patients with Alzheimer's disease or other dementias. It is particularly relevant because it is rated on scripted questions administered to caregivers.19
