What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Extramel 10 mg - 140 UI SODDietary supplement

    Subjects took one capsule of Extramel® 140 IU, or its corresponding placebo, daily over 12 weeks.

    Each volunteer was seen for the 3 visits:

    • visit V1, so-called inclusion visit (D0),
    • visit V2 at 28 days, tolerance of +/- 3 days, (D28) and
    • visit V3 at 84 days, tolerance of +/- 3 days, (D84).
  • Placebo - Excipient onlyDietary supplement

What is being measured

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

  1. Perceived Stress : Change from base line in Cohen PSS 14 scale at V2 and V3

    Evaluation performed by Cohen PSS 14 scale. It should be noted that in order to be included the patient had to present a minimum score of 30 on the Cohen scale.

    Measured: Evaluation performed at inclusion day (V1), after 4 weeks at D28 (V2) and then at the end of study visit on D84 (V3).

Secondary outcomes (6)
  1. Evaluation of evolution of Physical fatigue

    Evaluation performed by Prevost subjective fatigue scale and Ruffier test.

    Measured: Evaluation performed at inclusion day (V1), after 4 weeks at D28 (V2) and then at the end of study visit on D84 (V3).

  2. Evaluation of evolution of Intellectual fatigue

    Evaluation performed by Stroop test, Reverse Stroop test and 15-words Rey test.

    Measured: Evaluation performed at inclusion day (V1), after 4 weeks at D28 (V2) and then at the end of study visit on D84 (V3).

  3. Evaluation of evolution of pain

    Evaluation of subjects' perceived chronic pain (if existing), was performed using a simple visual analog scale (VAS).

    Measured: Evaluation performed at inclusion day (V1), after 4 weeks at D28 (V2) and then at the end of study visit on D84 (V3).

  4. Evaluation of evolution of subject Quality of life

    Evaluation of subjects' quality of life, was performed by using Quality of Life SF36 scale.

    Measured: Evaluation performed at inclusion day (V1), after 4 weeks at D28 (V2) and then at the end of study visit on D84 (V3).

  5. Evaluation of evolution of subject Quality of life

    Evaluation of subjects' quality of life, was performed by using Hamilton anxiety scale.

    Measured: Evaluation performed at inclusion day (V1), after 4 weeks at D28 (V2) and then at the end of study visit on D84 (V3).

  6. Evaluation of evolution of subject Quality of life

    Evaluation of subjects' quality of life, was performed by using Personnal stress profile questionnary.

    Measured: Evaluation performed at inclusion day (V1), after 4 weeks at D28 (V2) and then at the end of study visit on D84 (V3).

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Extramel 10 mg - 140 UI SOD in people with Life Stress and Fatigue, run by Robertet SA.

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 16 inclusion and 10 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 18 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.

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 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?

Perceived Stress : Change from base line in Cohen PSS 14 scale at V2 and V3 (time frame: Evaluation performed at inclusion day (V1), after 4 weeks at D28 (V2) and then at the end of study visit on D84 (V3).). 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 NCT01767922, 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 18 Jan 2013; AzTrials last refreshed its copy on 31 Oct 2026.
