October 6, 2017 updated by: Jin-Dong Chen, Second Xiangya Hospital of Central South University

Safety, Effectiveness, and Mechanism of Fish Oil as Adjunct Treatment for Major Depressive Disorder - a 12-month Randomized, Placebo Controlled Clinical Trial

In this proposed study, the investigators will evaluate the effects of fish oil add-on in treatment of major depressive disorder(MDD).

Intervention / Treatment

Detailed Description

Participants are randomly assigned to two groups (n=60): control (placebo, soybean) and fish oil (containing EPA 1440mg, DHA 960mg). The experimental groups will be compared to placebo to evaluate if it may benefit clinical symptoms, cognitive symptoms and metabolic markers in MDD patients. We also plan to investigate the changes in markers of inflammation at the same time.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: experimental group
the experimental group will be given 4 fish oil capsules (1g/one capsule)twice daily after two meals at roughly the same time each day,lasting for the first 6 months.fish oil capsule will be provided by the Hunan Kangqi100 Biological Technology Co.Ltd.
Dietary supplement: fish oil capsule
N-3 PUFAs is a kind of essential fatty acid,however the formation is too slow. Studies show that intakes of N-3 PUFAs is associated with MDD.It have to be got from food like deep-sea fishes. EPA and DHA are crucial for the body.Although studies have shown that reduced N-3 PUFAs were correlated with MDD, and patients with an elevated rate of N-6 PUFAs /N-3 PUFAs or a low level of DHA may be at higher odds for suicide. Trials on whether N-3 PUFAs is effective in the treatment of MDD is still controversial, which might be affected by several factors, such as dose, duration etc.. Now there is no large-scale randomized controlled clinical trial in determining the effects of N-3 PUFAs add-on in treatment of MDD.
Placebo Comparator: control group
the control group will be given 4 soybean oil capsules ( placebo capsule,1g/one capsule) twice daily after two meals at roughly the same time each day,lasting for the first 6 months.placebo capsule will be provided by the Hunan Kangqi100 Biological Technology Co.Ltd.The placebo capsule's appearance and flavor are made the exactly the same as the fish oil capsules .
Dietary supplement: soybean oil capsule
placebo capsule
