Descriptive Information
Brief Title ICMJE	Rivastigmine Monotherapy and Combination Therapy With Memantine in Patients With Moderately Severe Alzheimer's Disease Who Failed to Benefit From Previous Cholinesterase Inhibitor Treatment
Official Title ICMJE	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
Brief Summary	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.
