About this study

The purpose of this study is to determine whether Pioglitazone as an adjunct to Citalopram is effective in treatment of moderate to severe depression

Read the detailed description

Pioglitazone as a Ppar-gamma agonist is an anti diabetic drug. It was also shown that, it has certain anti inflammatory and neuro-protective effects. In recent years it has been proposed that Ppar-gamma agonists may have effects on mood and cognition. In animal studies and in one human case report as well as a pilot study on human subjects these drugs improved symptoms of depression. A randomized controlled and double blind design will provide further evidence for the efficacy of these drugs in major depressive disorder.

What is being measured

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

  1. Scores of Hamilton Depression Rating Scale (17 items) at the end

    Hamilton Depression rating scale is a 17-item scale. The questionnaire rates the severity of symptoms observed in depression such as low mood, insomnia, agitation, anxiety and weight loss. The questionnaire is presently one of the most commonly used scales for rating depression in medical research. The primary outcome measure is Scores on Hamilton Depression Rating Scale at the end (week 6)

    Measured: week 6

Secondary outcomes (2)
  1. Number of Adverse events in each group

    Measured: week 2,4,6

  2. Scores of Hamilton Depression Rating Scale (17 items)

    Measured: week 0,2,4

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Pioglitazone+Citalopram+Chlordiazepoxide in people with Major Depressive Disorder, run by Tehran University of Medical Sciences at 1 site in Iran.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 May 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Iran. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Scores of Hamilton Depression Rating Scale (17 items) at the end (time frame: week 6). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01109030, which also lists 5 linked publications.

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 9 May 2012.
