Embodiment 1

[0286] Treatment example 1: Memantine in patients with moderate to severe Alzheimer's disease behavioral consequences

[0287] Patients with moderate to severe AD were randomized to either placebo or 20 mg daily memantine for 28 weeks. The first efficacy variables were impressions of change based on clinician's interview plus information provided by caregiver (CIBIC-Plus) and Alzheimer's Disease Collaborative Study Activities of Daily Living Record (ADCS-ADL) altered for severe dementia. Secondary efficacy variables included severe impairment (SIB) and neuropsychiatric records (NPI). Treatment differences between baseline and endpoints were assessed. Incomplete observations take the most recent previous observation (last observation carried forward - LOCF). Results were also analyzed using only observed values ​​where missing values ​​were not replaced (analysis of observed cases (OC)). AD patients (N=252), (67% female, mean age=76 years) were randomized from 32 US clin...

Embodiment 2

[0318] Treatment example 2: In patients with moderate to severe Alzheimer's disease, memantine and Effects of co-administration of donepezil on behavioral outcomes

[0319]A 24-week, double-blind, placebo-controlled trial was conducted in moderate to severe Alzheimer's disease patients (N=404) undergoing donepezil therapy and randomized to memantine or placebo. Behavioral symptoms were assessed using the NPI at baseline, week 12, and the final visit (week 24). The trial has identified benefits of memantine on functional, cognitive and global measures. Statistical analysis was based on the ITT population using the carried forward last observation (LOCF) and observed cases (OC) approach.

[0320] Therapeutic benefit of memantine in combination with stable doses of commonly used AChEIs was observed on behavioral (NPI) measures in patients with moderate to severe Alzheimer's disease (MMSE mean at entry 10). Memantine treatment resulted in significant improvements compared to...

Embodiment 3

[0373] This example presents the results of five (5) clinical trials, two of which are described above in Example 1 (MZ-9065) and Example 2 (MD-02). In addition, the results of two additional trials, MD-01, MD-10 and MD-12 are presented.

[0374] MD-01: MD-01 is a trial evaluating memantine as monotherapy for 24 weeks in patients with moderate to severe AD. Approximately 350 patients participated. Efficacy was assessed using Severe Impairment (SIB), Assessment of Daily Living (ADL) and CIBIC-plus Scales.

[0375] MD-10: MD-10 is a randomized, double-blind, placebo-controlled evaluation of the safety and efficacy of memantine in patients with mild to moderate dementia of the Alzheimer's type. The primary endpoints of MD-10 are ADAS-cog and CIBIC-plus. Other endpoints of the MD-10 include ADCS-ADL, NPI and RUD (Resource Utilization in Dementia).

[0376] MD-12 : MD-12 is a randomized, double-blind, placebo-controlled evaluation of the safety and efficacy of memantine i...

Abstract

The present invention relates to the treatment of behavioral disorders, especially agitation, associated with a central nervous system (CNS) disorder, especially Alzheimer's disease (AD), cerebrovascular disease (VaD), or Down's Syndrome, in a mammal, comprising administering to said mammal an 1-aminocyclohexane, alone or in combination with a acetylcholinesterase inhibitor. In one embodiment, the 1-aminocyclohexane is memantine.

Description

technical field [0001] The present invention relates to the treatment of behavioral disorders associated with central nervous system (CNS) disorders, especially Alzheimer's disease (AD), cerebrovascular disease (VaD), or Down's syndrome in mammals, comprising the addition of 1-aminocyclic Hexane alone or in combination with an acetylcholinesterase inhibitor is administered to the mammal. Background technique [0002] Alzheimer's disease [0003] Dementia is a serious condition that affects up to 10% of individuals over the age of 65 and greater than 24% of those over the age of 85 (Hofman et al., Int. J. Epidemiol., 1991, 20:736-748; Jorm. and Jolley, Neurology, 1998, 51: 728-733; Lobo et al., Neurology, 2000, 54(Suppl. 5): S4-S9). Alzheimer's disease (AD) is an increasingly prevalent form of neurodegenerative disease, accounting for approximately 50%-60% of all cases of dementia in persons over the age of 65. AD is clinically characterized by progressive loss of memory,...
