About this study

Official title: Retrospective Observational Study to Estimate the Duration of Initial Antidepressant Treatment in Patients With Recurrent Depressive Disorder Who Demonstrated a Suboptimal Response to Therapy: DIANA Study

This Non-Interventional Study (NIS) is intended to evaluate the duration of treatment with an initial antidepressant taken as monotherapy in patients in whom treatment was changed because of suboptimal response at physician's discretion. This will address unmet medical needs of patients with a depressive episode related to RDD (ICD-10, Version 2010), who have failed to respond adequately to initial treatment with an antidepressant and contribute to an understanding of the usual approaches that physicians adopt to monitor initial treatment efficacy in RDD (Recurrent Depressive Disorder). The study will also focus on second-line therapy in hard to treat patients, describing the different pharmacotherapeutic strategies.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Duration of treatment considered as time between initiation of antidepressant monotherapy and the alteration and/or augmentation of pharmacotherapy

    Primary objective: The primary objective of this NIS is to evaluate the duration of treatment with an initial antidepressant taken as monotherapy in patients in whom treatment was changed because of suboptimal response at physician's discretion.

    Measured: up to 6 months

Secondary outcomes (4)
  1. Pharmacotherapy strategy for the second line treatment

    Distribution of the various pharmacotherapy strategies following suboptimal response: (switch; augmentation; combination of switch and augmentation and discontinuation of pharmacotherapy) among the patients population.

    Measured: up to 6 months

  2. International Non-Proprietary Name (INN) of pharmacological agents prescribed for augmentation

    Rate of the different pharmacological agents prescribed for augmentation; rout of their administration; mean and median duration of courses of treatment

    Measured: Up to 6 months

  3. Doses of pharmacological agents used for augmentation

    Mean and median doses of pharmacological agents used for augmentation

    Measured: Up to 6 months

  4. Source of the patient's referral to a psychiatrist

    Distribution of various sources of the patient's referral to a psychiatrist (psychotherapist; neurologist; internist; physician of other speciality; psychologist; came himself; other; and not known

    Measured: up to 6 months

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Duration of treatment considered as time between initiation of antidepressant monotherapy and the alteration and/or augmentation of pharmacotherapy (time frame: up to 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Nov 2014.
