Rivastigmine Monotherapy and Combination Therapy With Memantine in Patients With Moderately Severe Alzheimer's Disease Who Failed to Benefit From Previous Cholinesterase Inhibitor Treatment

This study has been completed.

Novartis Identifier:
First received: October 5, 2005
Last updated: November 16, 2011
Last verified: November 2011
This is a prospective, multicenter, open-label study. Following screening and baseline assessments, eligible patients will be switched to rivastigmine and will enter the 16 week run-in rivastigmine treatment phase. After completion of assessments at the end of the run-in phase, patients who were not sufficiently stabilized on rivastigmine alone will receive add-on memantine to their rivastigmine treatment; patients who were stabilized on rivastigmine alone will have completed and be discontinued from the study.

Condition Intervention Phase
Alzheimer's Disease Drug: Rivastigmine, memantine Phase 4

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open-label Study to Evaluate the Efficacy and Safety of add-on Memantine [5-10 mg b.i.d (10-20 mg/Day)] to Rivastigmine [1.5-6 mg b.i.d. (3-12 mg/Day)] Treatment in Patients With Alzheimer's Disease Who Continued With Rivastigmine Treatment After a Previous Decline While on Donepezil or Galantamine Treatment

Secondary Outcome Measures:
  • Change in cognition at weeks 16 and 28 (end of period 1) compared to baseline
  • Change in caregiver burden at weeks 16 and 28 (end of period 1) compared to baseline
  • Change in behavior at weeks 16 and 28 (end of period 1) compared to baseline
  • Change in executive function at weeks 16 and 28 (end of period 1) compared to baseline

Enrollment: 204
Study Start Date: November 2003
Study Completion Date: June 2005
Primary Completion Date: June 2005 (Final data collection date for primary outcome measure)

Ages Eligible for Study:   50 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Outpatients who have probable Alzheimer's disease according to the DSMIV criteria
  • Patients treated with donepezil (5-10 mg ) or galantamine (16- 24 mg) for at least 6 months
  • Patients, in the investigator's clinical judgment, not stabilized on treatment with donepezil or galantamine

Exclusion Criteria:

  • Patients with evidence of severe or unstable physical illness, i.e., acute and severe asthmatic conditions, severe or unstable cardiovascular disorders, active peptic ulcer disease, hypersensitivity to cholinesterase inhibitors or memantine, clinically significant laboratory abnormalities or any patient with a medical condition which would prohibit them from completing the clinical trial
