Acupuncture and Escitalopram for Treating Major Depression Clinical Study (AE-TMDCS): protocol for a factorial randomised controlled trial.

Abstract

Major depressive disorder (MDD), the second leading cause of disability globally, is considered to be associated with a consequent deterioration in the quality of life and can lead to a major economic burden on medical service and suicide-related costs. Previous research has shown that acupuncture may be beneficial for treating MDD. However, there is a lack of rigorous evidence from previous studies comparing acupuncture with antidepressant medications. This study aims to assess the therapeutic potential of acupuncture in the management of depressive disorders. A multicentre, randomised, participant-blind, sham-controlled, 2×2 factorial clinical trial, Acupuncture and Escitalopram for Treating Major Depression Clinical Study, aims to compare the efficacy of acupuncture versus escitalopram in treating depression. This study will be conducted at three hospitals in China, enrolling 260 patients with moderate-to-severe major depression, as defined by DSM-5 criteria and Hamilton Depression Rating Scale (HDRS-17) Scores above 17. Participants will be randomly assigned in equal proportions to one of four groups (acupuncture/escitalopram, sham acupuncture/escitalopram, acupuncture/placebo and sham acupuncture/placebo) and undergo 30 sessions across 10 weeks. The primary outcome is change in HDRS-17 Score and secondary outcomes include BDI, Clinical Global Impression, Generalised Anxiety Disorder-7 and Mini-Mental State Examination Scores, alongside potential biological markers. Ethical approval for the study was granted by the Ethics Committees of the Seventh People's Hospital of Shanghai University of Traditional Chinese Medicine (2023-7th-HIRB-020), Shanghai Mental Health Centre (2022-86) and Shanghai Pudong New Area Hospital of Traditional Chinese Medicine (2023-003). Informed consent will be obtained from all participants. The study's findings are intended for publication in a scholarly journal. NCT05901571.
