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

Sponsored by:	Novartis
Information provided by:	Novartis
ClinicalTrials.gov Identifier:	NCT00234637

Purpose

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.

Criteria

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
