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.

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)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Female or male aged 18 to 65 years (inclusive).

  • Have a primary DSM-5 diagnosis of current MDD.

    1. The duration of the current MDE must be at least 12 weeks.
    2. Without psychotic or catatonic features.

Exclusion Criteria:

  • Psychiatric History:

    1. Diagnosis of DSM-5-defined lifetime bipolar disorder (I, II, or unspecified), schizophrenia, schizoaffective disorder, MDD with psychotic features, other psychotic disorder, or antisocial personality disorder; current (past month) obsessive-compulsive disorder; current (past month) posttraumatic stress disorder; current (past 3 months) anorexia nervosa; lifetime opioid or lifetime sedative-hypnotic use disorders, as confirmed by the MINI 7.0.2.
    2. Diagnosis of borderline personality disorder
    3. Patients with comorbid generalized anxiety disorder (GAD), social anxiety disorder (SAD), or panic disorder are excluded only if the GAD, SAD, or panic disorder is considered the primary psychiatric diagnosis, rather than MDD. (If MDD is the primary diagnosis, patients with comorbid GAD, SAD, and panic disorder are allowed for randomization).
  • Patients with treatment refractory MDD, ie, previously having in their lifetime failed ≥2 treatments with at least 2 different classes of antidepressants of adequate dose, duration, and treatment adherence

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
Montgomery Asberg Depression Rating Scale (MADRS)
Time Frame: Day 1 and Week 6
Change from Baseline (Visit 2) in the MADRS total score at Week 6. Scores range from 0 to 60. Lower scores indicate less depression.
Day 1 and Week 6

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
Clinical Global Impression of Severity (CGI-S)
Time Frame: Day 1 and Week 6
Change from Baseline (Visit 2) in the Clinical Global Impression of Severity Scale (CGI-S) score at Week 6. Scores range from 1 to 7. Lower scores indicate less severe illness.
Day 1 and Week 6
Sheehan Disability Scale (SDS)
Time Frame: Day 1 and Week 6
Change from Baseline (Visit 2) in the Sheehan Disability Scale (SDS) total score at Week 6. Scores range from 0 to 30. Lower scores indicate less impairment to activities.
Day 1 and Week 6

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
