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.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

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: Light therapy
In this group, participants will be exposed to the LED treatment device (light box) which delivers bright light and meanwhile medicated with just one particular antipsychotics drug(a mood stabilizer or an atypical antipsychotic drug)except of antidepressants.
Device: Bright Light therapy
In this group, participants will be exposed to the LED treatment device (lightbox) which delivers bright light and meanwhile medicated with just one particular antipsychotics drug(a mood stabilizer or an atypical antipsychotic drug)except of antidepressants.
Placebo Comparator: Control group
In this group, participants will be exposed to the same LED treatment device (light box) which delivers dim red light,which is considered to be biologically inactive, and meanwhile medicated with just one particular antipsychotics drug(a mood stabilizer or an atypical antipsychotic drug)except of antidepressants.
Device: dim Red Light therapy
In this group, participants will be exposed to the same LED treatment device (light box) which delivers dim red light,which is considered to be biologically inactive, and meanwhile medicated with just one particular antipsychotics drug(a mood stabilizer or an atypical antipsychotic drug)except of antidepressants.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Reducing rate of HAMD
Time Frame: Change from baselin to 2 weeks after
We used HAMD to evaluate the major state of depression.
Change from baselin to 2 weeks after

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Reducing rate of CGI
Time Frame: Change from baseline to 2 week after
We use CGI to evaluate the state of depression.
Change from baseline to 2 week after
