Clinical Trial Summary

Despite the availability of a wide range of antidepressant drugs, clinical trials indicate that 30% to 40% of patients with major depression fail to respond to first-line antidepressant treatment, despite adequate dosage, duration, and compliance. Moreover, in those patients who do experience symptomatic relief following conventional anti-depressant treatment, clinical improvement is not evident for 3-4 weeks. Thus, there is a clear need to develop novel and improved therapeutics for unipolar depression.

A previous study showed that the intravenous administration of scopolamine produces antidepressant effects. This study is designed to determine if scopolamine combine with Escitalopram produce antidepressant effects at an early stage.

Description:

This study is a randomized, double-blind, placebo-controlled clinical trial. Sixty-six outpatients (ages 18-45) with severe major depressive disorder (MDD) (17-item Hamilton Rating Scale for Depression total score greater than or equal to 20) are enrolled from Beijing Anding Hospital. All participants receive oral escitalopram 10 mg/d throughout the total of 4 weeks treatment. Meanwhile, they are randomized equally to one of three add-on treatment arms during the first three days: (1) intramuscular injection (i.m.) with saline (1 ml) at 9 am and 3 pm per day; (2) scopolamine (0.3 mg in 1ml saline, i.m.) at 9 am and saline (1 ml, i.m.) at 3 pm per day; (3) scopolamine (0.3 mg in 1ml saline, i.m.) at 9 am and 3 pm per day, respectively. Patients were assessed at baseline, day 2, day 3, day 4, day 7, day 14, and day 28 using 17-Item Hamilton Depression Rating Scale(HAMD-17), Montgomery-Asberg Depression Rating Scale(MADRS), Young Mania Rating Scale(YMRS), Generalized Anxiety Disorder-7(GAD-7), Quick Inventory of Depressive Symptomatology Self-report 16(QIDS-SR16) and Clinical Global Impression(CGI) by assessors masked to treatment assignments. The primary outcome measure was the time from randomization (baseline) to early improvement (at least 20% reduction in HAMD-17 score ). The second outcome measures were response rates (at least 50% decrease in the HAMD-17 at any visit from baseline), remission rate (HAMD-17 score≤7) at day 28, change in HAMD-17 score ,MADRS score, QIDS-SR16 score, GAD7 score and YMRS score from baseline to any visit, change in CGI-S from baseline to the end of the trial, and CGI-I score at any visit.
