Clinical Trial Summary

The purpose of this study is to investigate whether the addition of galantamine to a commonly used antidepressant, escitalopram (Lexapro), will be useful in the treatment of memory and other thinking problems that are frequently seen in depression. At present, galantamine is approved for use in the treatment of Alzheimer’s disease or dementia, but not for use for the treatment of depression in younger patients.

Possible genetic effects of depressed individuals will also be studied. This study is involved in collecting blood from patients with depression. DNA, the genetic material in our cells, will be obtained from these blood samples. The DNA will be studied to determine the contribution of different genes to the development of depression. These blood samples are extremely useful to researchers who are trying to determine the genetic risk factors that may lead to depression.

Description:

HYPOTHESES/OBJECTIVES

Aim 1: To investigate whether patients treated with escitalopram in combination with galantamine will show a significantly greater improvement of depression compared to patients treated with escitalopram alone.

H1: Patients treated with escitalopram and galantamine combination will have significantly greater improvement on the Hamilton Depression Rating Scale (HDRS) and Clinical Global Improvement (CGI) scale compared to patients treated with escitalopram and placebo.

Aim 2: To investigate whether treatment with escitalopram in combination with galantamine will lead to a greater improvement of cognitive function in depressed patients compared to escitalopram alone.

H2: Patients treated with escitalopram and galantamine combination will have significantly greater improvement of scores on Selective Reminding Test (SRT) and Trail Making Test (TMT) than patients treated with escitalopram and placebo.

Study Design and Method:

This will be a randomized, single blind, parallel-group, placebo controlled study in which a total of 20 subjects, 10 in each arm: one arm would be escitalopram + galantamine treatment and the other arm will be escitalopram + placebo treatment. The subject will be blinded against the galantamine or placebo, but will be unblinded against escitalopram. The total duration of this study will be 10 weeks. After the baseline visit, patients will complete 8 weeks of the study medication.
