Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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
