About this study

The aim of the study is to determine the influence of supplementation of probiotic Lactobacillus Plantarum 299V vs. placebo of probiotic during antidepressant monotherapy with SSRI (Selective Serotonin Reuptake Inhibitor) in patients with major depression.

Read the detailed description

For period of 8 weeks patient will receive probiotic Lactobacillus Plantarum 299V or its placebo as a supplementation of regular depression treatment with SSRI (Escitalopram or Sertraline). Psychometric and biochemical parameters will be monitored and evaluated. At day one, after 3 weeks (day 21) and after 8 weeks (day 56) of the study psychometric parameters will be measured such as Hamilton Depression Rating Scale, PSS-10 Scale, SCL-90 scale. At day one and after 8 weeks (day 56) of the study cognitive functions will be measured using: CVLT- California Verbal Learning Test, RFFT Ruff Figural Fluency Test, Stroop Test, Connecting Points Test (A and B), Attention and Perceptivity Test. At day one and after 8 weeks (day 56) of the study biochemical parameters will be measured such as: morning cortisol, pro and anti-inflammatory cytokines, tryptophan and its kynurenic pathway metabolites concentrations.

  3. Evaluation of psychometric parameters - Change in Symptom Checklist 90 Scale (SCL-90) from baseline at 3 weeks and 8 weeks of the study.

    Measured: At day one, after 3 weeks (day 21), after 8 weeks (day 56) of the study

Secondary outcomes (8)
  1. Cognitive functions evaluation - California Verbal Learning Test (CVLT)

    Measured: At day one, after 8 weeks (day 56) of the study

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Lactobacillus Plantarum 299v, Crystalline cellulose powder and Escitalopram in people with Depression and Anxiety Disorder, run by Medical University of Bialystok at 1 site in Poland.

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 1 inclusion and 9 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 7 Sep 2018. 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 Poland. 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 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.

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?

Evaluation of psychometric parameters - Change in Hamilton Depression Rating Scale from baseline at 3 weeks and 8 weeks of the study. (time frame: At day one, after 3 weeks (day 21), after 8 weeks (day 56) of the study). The study lists 3 primary outcomes in all. 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 7 Sep 2018.
