15. Patients with swallowing difficulties.

Exclusion Criteria:

1. Any medical or neurological condition other than AD that could explain the patient's dementia (e.g., abnormal thyroid function tests, vitamin B12 or folate deficiency, posttraumatic conditions, syphilis, head injury, Huntington's disease, Parkinson's disease, subdural hematoma, normal pressure hydrocephalus, brain tumor) at baseline

2. Any other DSM-IV Axis 1 diagnosis that may interfere with the evaluation of the patient's response to study medication, including other primary neurodegenerative dementia, schizophrenia, or bipolar disorder

3. An advanced, severe, progressive, or unstable disease of any type that may interfere with efficacy and safety assessments or put the patient at special risk

4. Current diagnosis of an active skin lesion/disorder

5. Patients with a history of hypersensitivity to any ingredients of rivastigmine or carbamate derivatives

6. Each patient will be required to have a primary caregiver willing to accept responsibility for supervising treatment, assessing the patient's condition throughout the study, and for providing input into efficacy assessments.

Other protocol-defined inclusion/exclusion criteria may apply.

Intervention

Drug:
Rivastigmine Patch
Alzheimer's disease patient who is applicable to 1 step titration method (initial loading dose is a rivastigmine patch 9.0 mg/day and will be up-titrated after 4 weeks to reach the maintenance dose of 18 mg/day). Rivastigmine patch is a marketed drug, therefore the dose, dose regimen and titration scheme are in accordance with product label.

Outcome

Type Measure Description Time frame Safety issue
Primary MMSE Total Score: Change From Baseline to Week 8 and Week 24 (Full Analysis Set) Evaluation of the efficacy of rivastigmine patch with 1-step titration on cognitive function measured as change from baseline to week 24 in the total score of MMSE in mild to moderate Alzheimer's disease (AD) patients who failed to benefit from other cholinesterase inhibitors (ChEIs)
The MMSE is a screening test for cognitive dysfunction. The test consists of five sections (orientation, registration, attention-calculation, recall, and language); the total score can range from 0 to 30, with a higher score indicating better function. A positive change score indicates improvement from baseline.
Abbreviated Scale title: Mini Mental State Evaluation Minimum Score: 0 Maximum score: 30 Higher score indicated better cognitive function
baseline, weeks 8 and 24
Secondary MMSE Total Score: Change From Baseline to Week 8 and Week 24 Evaluation of the safety, tolerability of rivastigmine patch with 1-step titration for up to 24 weeks.
Per Protocol, The MMSE is a brief, practical screening test for cognitive dysfunction. The MMSE consists of 2 parts: language (time orientation, registration and attention) and performance (recall, response to written/verbal commands, writing ability and reproduction of complex polygons), and the total possible score is 30. Lower score indicates more severe impairment. It is the most common and simple cognitive scale for Alzheimer's disease.
Unabbreviated Scale : MMSE - Mini Mental State Evaluation:
Minimum values - 0 Maximum value - 30 Higher Value means a better outcome
Positive change score from baseline indicates improvement in cognitive function
baseline, weeks 8 and 24
Secondary Change From Baseline to Week 8 in Mini-Mental State Examination (MMSE) Total Score Evaluation of the efficacy of rivastigmine patch with 1-step titration measured as the MMSE score at week 8 for patients who had 1-step titration
MMSE total score: change from baseline to Week 8 and Week 24 for patients who had 1-step titration
Unabbreviated Scale : MMSE - Mini Mental State Evaluation:
Minimum values - 0 Maximum value - 30 Higher Value means a better outcome
Positive change score from baseline indicates better outcome
baseline and week 8
Secondary Change in Neuropsychiatric Inventory - 10 Item (NPI-10) Score From Baseline to Week 8 and Week 24 Evaluation of the efficacy of rivastigmine patch with 1-step titration measured as the Neuropsychiatric Inventory - 10 Item (NPI-10) score at week 8 and week 24.
Per protocol, Neuropsychiatric The NPI-10 total score is a sum of the 10 items, where the score for a domain is defined as the product of frequency (range: 1-4) and severity (range: 1-3). Each domain has a maximum score of 12 and all domains are equally weighted for the total score (thus the range for the total score is 0 to 120).
A higher score indicates more severe impairment.
Neuropsychiatry Inventory - 10 Minimum Score = 0 Maximum Score = 120
Higher Score indicates worse outcome
baseline, week 8, week 24
Secondary Change in QOL-AD Score From Baseline to Week 24 Evaluation of the efficacy of rivastigmine patch with 1-step titration measured as QOL-AD score at week 24.
Unabbreviated Scale Name: Quality of Life - Alzheimer's Disease Minimum Score = 13 Maximum Score = 52
Higher value indicates a better outcome
QOL-AD is a 13-item questionnaire to assess the quality of life of Alzheimer's patients from the perspectives of patients and their caregivers. It covers several aspects, for example, the perception of health status, mood, functional capacity, personal relationships and leisure, financial situation, and life as a whole. Each item is quantified using a Likert scale with score one classified as poor, and score four as excellent where total scores range from 13 to 52. A lower score indicates more severe impairment.
baseline and week 24
Secondary Change in J-CGIC Score From Baseline and at Week 24 Evaluation of the efficacy of rivastigmine patch with 1-step titration measured as the The Japanese-Clinical Global Impression of Change (J-CGIC) score at baseline and week 24
J-CGIC is a 7-grade investigator's impression scale: 1. Markedly improved, 2. Improved, 3. Slightly improved, 4. No change, 5. Slightly aggravated, 6. Aggravated, 7. Markedly aggravated
At week 24, 103 patients had available data
Total score is in the 0 to 56 range. Higher score means more severe impairment.
Unabbreviated scale title: Japanese -Cinical Global Impression of Change Minimum Score - 1 Maximum Score - 7

Secondary Change in as Modified Crichton Scale Score From Baseline to Week 4, 8, 16 and 24 Evaluation of the efficacy of rivastigmine patch with 1-step titration measured as Modified Crichton Scale score week 4, week 8, week 16, and week 24.
Modified Crichton Scale that assess basic activation of daily living, communication functions, and quality of life The following 7 items will be evaluated by caregiver. Total score is in the 0 to 56 range. Higher score means more severe impairment.
Unabbreviated Scale Title: Modified Crichton scale Minimum score = 0 Maximum Score = 56 Higher score indicates worse outcome
baseline, weeks 4, 8, 16, 24
Secondary Formulation Usability Questionnaire Form Score up to Week 24 Evaluation of the formulation usability of rivastigmine patch for up to 24 weeks as measured by the formulation usability questionnaire answered by caregiver.
The Formulation usability preference questionnaire had been used to compare the previous oral AD drugs versus the patch The caregiver selects one of the following answers (1. Very easy to use, 2. Easy to use, 3. No change, 4. Not easy to use, 5. Not easy to use at all, 6. Unknown).
This questionnaire data is used to assess if the usability of rivastigmine patch was preferred by the majority (> 50%) of AD patient caregivers or not.
Unabbreviated Questionnaire title:
Formulation Usability questionnaire Minimum Score = 1 Maximum Score = 6
A higher score indicates its not easy to use and worse outcome.
Up to week 24
