AZD7268 Safety and Tolerability Study

April 11, 2012 updated by: AstraZeneca

A Phase II, Multi-center, Randomized, Double-bind, Double-dummy, Active and Placebo Controlled, Parallel Group Study to Assess the Efficacy and Safety of AZD7268 in Patients With Major Depressive Disorder

The purpose of this study is to prove the principle that treatment with AZD7268 reduces depressive symptoms in patients with Major Depressive Disorder (MDD) compared with placebo.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

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

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Provision of signed, written, and dated Informed Consent prior to any study specific procedures
  • Documented primary clinical diagnosis meeting criteria from the DSM-IV, Text Revision (APA 2000) for any of the following:
  • 296.2x Major Depressive Disorder, Single Episode, or
  • 296.3x Major Depressive Disorder, Recurrent

Exclusion Criteria:

  • Patients with a secondary DSM-IV Axis I disorder other than GAD or social anxiety disorder (as assessed by MINI), provided the primary diagnosis is MDD. This diagnosis should have been made at least 6 months before enrollment
  • Patients with a diagnosis of DSM-IV Axis II disorder which has a major impact on the patient's current psychiatric status
  • Patients whose current episode of depression started less than 4 weeks before enrollment

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-Åsberg Depression Rating Scale (MADRS) Total Score Change From Baseline to Week 4.
Time Frame: Baseline, Week 4
MADRS total score, sum of 10 item scores (each on a 0 (best value) to 6 (worst value)scale), assesses the severity of depressive symptoms on a continuous scale from 0 (the best) to 60 (the worst). Change from baseline was calculated as Week 4 value minus baseline value. [observed cases, Mixed Model Repeated Measurement (MMRM), Full Analysis Set (FAS)]
Baseline, Week 4

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-Åsberg Depression Rating Scale (MADRS) Response
Time Frame: Week 4
Number of patients with MADRS response at Week 4. MADRS response is defined as >=50% reduction in MADRS total score from baseline. MADRS total score, sum of 10 item scores (each on a 0 (best value) to 6 (worst value)scale), assesses the severity of depressive symptoms on a continuous scale from 0 (the best) to 60 (the worst). MADRS response at Week 4 is calculated using last observation carried forward (LOCF). [Full Analysis Set (FAS)]
Week 4
Montgomery-Åsberg Depression Rating Scale (MADRS) Remission
Time Frame: Week 4
Number of patients, who achieved MADRS remission at week 4. Remission is defined as a MADRS total score <= 10. MADRS total score, sum of 10 item scores (each on a 0 (best value) to 6 (worst value)scale), assesses the severity of depressive symptoms on a continuous scale from 0 (the best) to 60 (the worst). MADRS remission at Week 4 is calculated using last observation carried forward (LOCF). [Full Analysis Set (FAS)]
Week 4
Hamilton Rating Scale for Depression (HAM-D) Total Score Change From Baseline to Week 4.
Time Frame: Baseline, Week 4
HAM-D total score, sum of 17 item scores (each on a 0 to 2 or 0 to 4 scale), assesses the severity of depressive symptoms on a continuous scale from 0 (the best) to 52 (the worst). Change from baseline to Week 4 was calculated as Week 4 value minus baseline value. [observed cases, Mixed Model Repeated Measurement (MMRM), Full Analysis Set (FAS)]
Baseline, Week 4
Clinical Global Impression - Severity (CGI-S) Score Change From Baseline
Time Frame: Baseline, Week 4
CGI-S assesses global illness severity, i.e. the patient's current clinical state, on a continuous scale from 1 ("Normal, not ill") to 7 ("Among the most extremely ill patients"). Change from baseline to Week 4 was calculated as Week 4 value minus baseline value. [observed cases, Mixed Model Repeated Measurement (MMRM), Full Analysis Set (FAS)]
Baseline, Week 4
Hamilton Rating Scale for Anxiety (HAM-A) Total Score Change From Baseline
Time Frame: Baseline, Week 4
HAM-A total score, sum of 14 item scores (each on a 0 to 4 scale), assesses the severity of anxiety symptoms on a continuous scale from 0 (the best) to 52 (the worst). Change from baseline to Week 4 was calculated as Week 4 value minus baseline value. [observed cases, Mixed Model Repeated Measurement (MMRM), Full Analysis Set (FAS)]
Baseline, Week 4

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.
