About this study

Official title: A Double-blind, Placebo-controlled Study Evaluating the Pharmacodynamic Effects of Two Fixed Doses of SSR149415 (250 mg Bid and 100 mg Bid) on Hypothalamic-pituitary-adrenal Axis Function in Outpatients With Major Depressive Disorder

Primary Objective:

  • To evaluate the effects of two fixed doses of SSR149415 (250 mg bid and 100 mg bid) on hypothalamic-pituitary-adrenal axis function in patients with major depressive disorder.

Secondary Objectives:

  • To evaluate the tolerability and safety of SSR149415 in patients with major depressive disorder.
  • To evaluate the efficacy of two fixed doses of SSR149415 compared to placebo in patients with major depressive disorder.
  • To evaluate plasma concentrations of SSR149415.
Read the detailed description

The study consisted of three segments (A, B and C). Segment A was a 1 to 4-week, drug-free, screening and baseline period. Segment B was a 4-week, double-blind period. After the last dose of double-blind study medication in Segment B, all patients had to enter Segment C, a 1-week drug-free, follow-up period.

The total study duration for one patient participating in all segments of the study was 6 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing VASOPRESSIN V1B RECEPTOR ANTAGONIST (SSR149415) in people with Major Depressive Disorder, run by Sanofi at 1 site in United States.

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 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 25 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 United States. 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?

Cortisol plasma concentration response to Corticotropin releasing factor (CRF) administration before and after 27 days of dosing (time frame: 4 weeks). 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 NCT01606384, which also lists 1 linked publication.

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 25 May 2012.
