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

14 years to 66 years (Adult, Older Adult)

Accepts Healthy Volunteers

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
Change From Baseline to the End of Treatment (EOT) in the Montgomery Asberg Depression Rating Scale-10 (MADRS-10) Scores
Time Frame: Baseline and 5 weeks for Stage 1, Baseline and 6 weeks for Stage 2
The MADRS-10 scale is a clinician-administered questionnaire comprised of 10 items used to measure the severity of Major Depressive Disorder (MDD) symptoms. Scores range from 0 (no apparent symptoms) to 60 (most severe symptoms). Individual questionnaire items include: Apparent Sadness, Reported Sadness, Inner Tension, Reduced Sleep, Reduced Appetite, Concentration Difficulties, Lassitude, Inability to Feel, Pessimistic Thoughts, and Suicidal Thoughts.
Baseline and 5 weeks for Stage 1, Baseline and 6 weeks for Stage 2

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
Montgomery Asberg Depression Rating Scale (MADRS) Response Rate
Time Frame: Baseline and 5 weeks for Stage 1, Baseline and 6 weeks for Stage 2
The percentage of subjects demonstrating a MADRS-10 treatment response, defined as a >/= 50% reduction in MADRS-10 score from baseline to the end of the efficacy period (Week 5 for Stage 1, Week 6 for Stage 2). The MADRS-10 scale is a measure of the severity of Major Depressive Disorder (MDD) symptoms and includes the following 10 items: Apparent Sadness, Reported Sadness, Inner Tension, Reduced Sleep, Reduced Appetite, Concentration Difficulties, Lassitude, Inability to Feel, Pessimistic Thoughts, and Suicidal Thoughts. Scores range from 0 (no apparent symptoms) to 60 (most severe symptoms).
Baseline and 5 weeks for Stage 1, Baseline and 6 weeks for Stage 2
Montgomery Asberg Depression Rating Scale (MADRS) Remission Rate
Time Frame: 5 weeks for Stage 1, 6 weeks for Stage 2
The percentage of subjects achieving remission, defined as a subject with a score </= 10 at the end of the efficacy period (Week 5 for Stage 1, Week 6 for Stage 2). The MADRS-10 scale is a measure of the severity of Major Depressive Disorder (MDD) symptoms and includes the following 10 items: Apparent Sadness, Reported Sadness, Inner Tension, Reduced Sleep, Reduced Appetite, Concentration Difficulties, Lassitude, Inability to Feel, Pessimistic Thoughts, and Suicidal Thoughts. Scores range from 0 (no apparent symptoms) to 60 (most severe symptoms).the end of the efficacy period.
5 weeks for Stage 1, 6 weeks for Stage 2

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
