NCT01025466

  Purpose

The primary objective is to compare the tolerability between rivastigmine patch monotherapy and combination therapy with memantine in patients with Alzheimer's disease (AD). The secondary objective is to compare the efficacy and safety between rivastigmine patch monotherapy and combination therapy with memantine in patients with AD. The study hypothesis is that the tolerability of the combination therapy with memantine is not inferior to that of rivastigmine patch monotherapy in AD patients.

Arms Assigned Interventions
Active Comparator: rivastigmine patch monotherapy Drug: Rivastigmine transdermal patch
All patients start on a 5-cm2 rivastigmine patch and their dose is increased to a 10-cm2 patch after 4 weeks. Patients will be randomly allocated to 1 of 2 treatment groups of rivastigmine patch monotherapy and combination therapy with memantine at the baseline visit (week 9)and treated with the drugs for 16 weeks.
Other Name: exelon patch
Active Comparator: Combination therapy with memantine Drug: Rivastigmine transdermal patch (Exelon patch), memantine
All patients start on a 5-cm2 rivastigmine patch and their dose is increased to a 10-cm2 patch after 4 weeks. Patients will be randomly allocated to 1 of 2 treatment groups of rivastigmine patch monotherapy and combination therapy with memantine at the baseline visit (week 9)and treated with the drugs for 16 weeks.
Other Name: exelon patch, ebixa

Detailed Description:

Recently, the rivastigmine patch demonstrated efficacy comparable to the highest doses of rivastigmine capsules, with markedly improved tolerability profile. We hypothesized that combination of memantine and rivastigmine patch will be safe and well tolerated and result in more clinical benefit in patients with AD in comparison with rivastigmine patch monotherapy, for the mechanisms of the drugs are different.

  Eligibility

Ages Eligible for Study:   50 Years to 90 Years
