About this study

Official title: Randomized, Double-blind, Placebo-controlled Trial to Assess the Impact of Probiotics on Skin Hydration in Adolescents and Young Adults with Mild Acne Vulgaris.

The goal of this clinical trials is to test the impact of probiotics on skin hydration in adolescents and young adults with mild acne. The hypothesis of this study is that the probiotic formulation is superior to placebo in improving the skin hydration in adolescents and young adults with minimal acne after 12 weeks of consumption.

Read the detailed description

This pilot study is a monocentric, randomized, double-blind, placebo-controlled, parallel-arm study. The product allocation will be performed using a dynamic randomization algorithm designed to minimize imbalance between the 2 arms, within the strata defined by 3 factors: age, Global Acne Evaluation (GEA) score and sex.

60 participants (adolescents and adults) with mild acne vulgaris will be recruited for this study, according to the following inclusion and exclusion criteria.

There will be a total of 3 study visits: V1 (screening and randomization), V2 (mid-study follow-up), and V3 (end-of-study). The study will last a total of 12 weeks.

What is being measured

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

  1. Corneal hydration after 12 weeks

    The primary endpoint of the study is to compare the absolute change of the hydration level of the facial cornea between baseline (visit V1) and visit V3, assessed with Corneometer® CM825 on the forehead expressed in arbitrary units (a.u.) ranging from 0 to 120 (<30: very dry skin; 30-40: dry skin; >40: normal hydrated skin).

    Measured: 12 weeks

Secondary outcomes (8)
  1. Corneal hydration of the forehead after 6 weeks

    The absolute change of the hydration of the facial cornea measured on the forehead with Corneometer® CM825 (expressed in a.u.) between V1 and V2, ranging from 0 to 120 (<30: very dry skin; 30-40: dry skin; >40: normal hydrated skin)).

    Measured: 6 weeks

  2. Transepidermal water loss of forehead skin

    The absolute change of the transepidermal water loss (TEWL) measured on the forehead with Tewameter® TM300expressed in g/h/m² (0-10: very healthy; 10-15: healthy; 15-25: normal; 25-30: stretched skin; >30: critical), between V1 and each visit (V2, V3).

    Measured: 12 weeks

  3. Symptoms of acne on face

    The absolute change of acne vulgaris symptoms (face and back) assessed with the Échelle de Cotation des Lésions d'Acné (acne grading scale; ECLA) scale between V1 and each visit (V2, V3), expressed in a.u, ranging from 0 to 5 on the face (0: no lesions; 1: <5; 2: 5-9; 3: 10-19; 4: 20-40; 5: > 40 lesions), and ranging from 0 to 3 on the back (0: absent; 1: few; 2: moderate; 3: important).

    Measured: 12 weeks

  4. Sebum levels on face

    The absolute change of sebum level (expressed in μg/cm²) measured with Sebumeter® SM815 between V1 and V3, ranging from 0 to 350, on the forehead (<100: dry skin; 100-220: normal skin; >220: oily skin).

    Measured: 12 weeks

  5. Disability caused by acne

    The absolute change of disability caused by acne assessed with the Cardiff Acne Disability Index (CADI) score (expressed in a.u., range 0-15) between V1 and each visit (V2, V3).

    Measured: 12 weeks

  6. Impact on quality of life

    The absolute change of overall Quality of Life, general health and four quality of life domains (Physical, Psychological, Social Relationships and Environment) assessed with six sub-scores of the World Health Organization Quality of life questionnaire - Brief version (WHOQoL-BREF) (expressed in a.u., item scores range 1-5, transformed scores range 0-100) between V1 and each visit (V2, V3).

    Measured: 12 weeks

  7. Self-assessment of acne level on face and back

    The absolute change of self-assessment acne level assessed with a visual analogue scale (VAS, range 0-10) between V1 and each visit (V2, V3).

    Measured: 12 weeks

  8. Self-assessment of treatment satisfaction

    The global study product satisfaction assessed with a visual analogue scale VAS (range 0-10) at V2 and V3.

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Probiotic in people with Acne Vulgaris and Hydration Acne, run by Lallemand Health Solutions at 1 site in France.

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 10 inclusion and 24 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 20 Sep 2024. 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 France. 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?

Corneal hydration after 12 weeks (time frame: 12 weeks). 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 20 Sep 2024.
