A Non Interventional Study to Investigating the Ratio of Mis-diagnosed Bipolar Symptoms in Patient With Major Depressive Disorder (MDD) (Improve)

March 22, 2012 updated by: AstraZeneca

A Non - Interventional Study to Investigating the Ratio of Mis-diagnosed Bipolar Symptoms in Patient Diagnosed as With Treatment Resistant Major Depressive Disorder (MDD)

The study will only detect hypomanic symptoms in treatment resistant MDD patients by mean of HCL-32 administration. Further re-evaluation of MDD diagnosis is not a direct aim of the study. No efficacy and tolerability of pharmacological treatments will be assessed. Patients matching inclusion and exclusion criteria will be enrolled consecutively; each investigator will include the first 10 to 40 patients that will be visited as treatment resistant MDD.

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

Sampling Method

Non-Probability Sample

Study Population

Patients with treatment resistant major depressive disorder will be evaluated in order to assess the presence of hypomanic symptoms as cause of resistance.

Description

Inclusion Criteria:

  • Written informed consent form
  • Male and Female age: 18-65 years
  • Diagnosis of MDD according to DSM-IV TR (296.3 x Major Depressive Disorder, recurrent)
  • Treatment resistance defined as non-response to at least 2 antidepressants given in an ade

Exclusion Criteria:

  • Patients already participating in clinical trial or any other interventional study
  • Patients unable to understand HCL-32 item meaning

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
MDD
Patients with treatment resistant major depressive disorder will be evaluated in order to assess the presence of hypomanic symptoms as cause of resistance.

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
To define the potential bipolarity status in treatment resistant MDD patient population
Time Frame: 3 months
assessment of presence of hypomanic symptoms, in order to reduce diagnostic mistakes leading to outcome worsening
3 months
Hypomanic condition will be defined if the patient will give positive answer to at least 12 items of HCL32. HCL-32-positive patients is expected to be ranged between 4.3% and 21.3%. The difference between the means in the two groups will be estimated.
Time Frame: 3 months
3 months

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
Time Frame
To collect patient characteristics by evaluation of demographic information
Time Frame: 3 months
3 months
To collect disease characteristics by evaluation of the number of previous episodes, and the duration of current episode
Time Frame: 3 months

To collect information on the ongoing treatment

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.
