Primary Outcome Measures:
  • To measure the differences between galantamine and donepazil for sleep and attention, explore methods of measuring sleep in patients with Alzheimer's Disease (AD)and their caregivers and attention in AD patients; GI tolerance

Secondary Outcome Measures:
  • To assess the tolerability, overall effect, quality of life and safety of galantamine compared with donepezil

Enrollment: 63
Study Completion Date: May 2003
Detailed Description:

This is designed as a pilot (preliminary) study to evaluate the differences in effects on attention, sleep problems and gastrointestinal tolerance associated with Alzheimer's Disease with two different drugs at two different doses. Patients must have mild to moderate Alzheimer's Disease based on the National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria and a Mini-Mental State Examination (MMSE) score of 10 to 24. The trial will consist of a 2-week run-in phase, an 8-week assessment phase, and an extension phase of variable length (6 weeks to 54 weeks). During the study, patients will be randomized (assigned by chance) to receive either galantamine or donepezil. Galantamine will be given by mouth 4mg twice daily for Weeks 1-4 and then 8mg twice daily for Weeks 5-8 and beyond (for participants in the extension). The patients on donezepil will receive 5mg by mouth at bedtime for Weeks 1-4 and then 10mg at bedtime for Weeks 5-8 and beyond. Placebo tablets will be given so that each patient takes two capsules per dose in order to conceal the identity of the drugs. Neither the patient nor the physician will know which drug the patient is receiving. Drug effectiveness will be measured by change in overall functioning of the patient shown by the Clinician's Interview-Based Impression of Change Plus Family Input (CIBIC-Plus). Other tests to evaluate whether the drug is effective will include the change in results of attention tests (Simple Reaction Time [SRT], Choice Reaction Time [CRT], Verbal Series Attention Test [VSAT], and Stroop Test), and in sleep pattern tests (tests that measure movements during sleep [Actiwatch] and patterns of sleep such as the caregiver-completed Pittsburgh Sleep Quality Index [PSQI] and the Circadian Sleep Inventory for Normal and Pathological States [CSINAPS]). Measures of quality of life will include the Alzheimer's Disease Related Quality of Life Scale (ADRQL) and the caregiver-completed Allocation of Caregiver Time Survey (ACTS) and SF-12 Quality of Life Survey. Safety assessment and gastrointestinal tolerability will be based on recording the number and severity of unexpected and undesirable events as well as physical examination and vital signs. The exploratory study hypotheses are that galantamine will be superior to donezepil in improving attention, sleep patterns, and quality of life in patients with mild-to-moderate Alzheimer's disease and that it will be well tolerated by patients.

Patients will receive either galantamine 4mg twice daily by mouth or donepezil 5mg at bedtime . Then, either galantamine 8mg twice daily by mouth or donezepil 10 mg at bedtime by mouth (with placebo dose); the doses are continued into the double-blind extension phase (6 to 54 weeks).

  Eligibility

Ages Eligible for Study:   60 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Male or post-menopausal female out-patients diagnosed with Alzheimer's disease
  • Patients should have mild to moderate dementia as evidenced by a Mini-Mental State Examination score of 10-24 inclusive at screening
  • The patient must show a history of cognitive decline that has been gradual in onset and progressive over a period of at least six months
  • There must be evidence of sustained memory deterioration in an otherwise alert patient, plus additional impairment in at least one of the following five areas: orientation, judgement and problem solving, functioning in community affairs, functioning in home and hobbies, or functioning in personal care
  • The caregiver resides with the patient and is able to speak with the investigative team about the patient's activities, medication use and adverse events. In addition, the caregiver will participate in assessment interviews and complete questionnaires for themselves and the patients. The caregiver will monitor their own sleep, the patient's sleep, and complete questionnaires regarding sleep patterns and care giving activities

Exclusion Criteria:

  • Neurodegenerative disorders such as Parkinson's disease, Pick's disease or Huntington's chorea, Down's syndrome, Creutzfeldt-Jacob disease
  • One of the following conditions possibly resulting in cognitive impairment: acute cerebral trauma or injuries secondary to chronic trauma, hypoxic cerebral damage, e.g., post resuscitation (cardiac arrest, post anesthesia, secondary to severe self-poisoning episode, or secondary to severe hypovolemia)
  • Patients with the following medical conditions: any history of epilepsy or convulsions except for febrile convulsions during childhood, clinically significant: endocrine disease, metabolic disease, psychiatric disease, cardiovascular disease, peptic ulcer disease, hepatic disease, renal disease, pulmonary disturbances or urinary outflow obstruction
  • Use of any agent for the treatment of dementia (approved, experimental or over the counter agents) including patients who have previously received tacrin, donepazil, metrifonate, rivastigmine tartrate, galantamine, or memantine for treatment of Alzheimer's disease
