About this study

Official title: EVALUATION of the EFFICACY and TOLERABILITY of TESTED FORMULA VS. HYDROQUINONE 4% in the TREATMENT of FACIAL MELASMA OVER 3 MONTHS

This study aims at assessing the non-inferiority of tested formula facial serum (2039125 03) versus hydroquinone 4% over 3 months for treatment and then 3 months for maintenance ofwomen subjects presenting facial melasma.

Read the detailed description

Topical treatments are usually used first line. Among a high number of molecules claiming a depigmenting effect, hydroquinone used at various concentrations (typically 2 to 5%) is the most widely used skin depigmenting product and is considered, up to now, the gold standard when used at 4-5%.

Hydroquinone is sometimes combined in the Kligman's trio, with topical tretinoin and topical steroids, which remains the best initial treatment for melasma in terms of efficacy.

This randomized , two-arm study is carried out with a new cosmetic formulation developed with the aim of acting on facial hyperpigmentation.

This clinical trial is conducted in accordance with the protocol, the HELSINKI declaration (1964) and subsequent amendments, and/or the International Council on Harmonization (ICH) Good Clinical Practices (GCP)/ and in compliance with applicable regulatory requirements.

Statistical Analysis:

  • Primary Efficacy Analysis: The primary performance endpoint is the difference between tested formula facial serum (2039125 03) versus hydroquinone 4% in mean change from baseline in modified Melasma Area Severity Index (mMASI) score at D84. A non-inferiority followed by a superiority evaluation will be assessed.
  • Sensitivity analyses The same analysis will be repeated on the FAS population. Missing values (i.e. data of patients who dropped out the study or with no evaluable data) will not be imputed for this analysis.

Depending on the results of the baseline characteristics description, other sensitivity analyses could be performed by adding other relevant baseline covariables to the model.

. Safety Analysis: no statistical analysis will be performed on safety. The data are presented descriptively.

Categorical data are summarized using the number and percentage of patients in each category. Continuous data are summarized using the arithmetic mean, Standard Deviation (SD), Q1, Q3, minimum, median and maximum values.

Regarding the sample size determination, there was no formal calculation. A number of 104 patients , 52 patients in each group was considered sufficient to meet the study objective.

What is being measured

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

  1. Change in mMASI scoring

    The mMASI is calculated using 3 components: four regions of the face (forehead, right malar, left malar and chin); area of involvement for each region (using a scale from 0 to 6): darkness compared to the surrounding normal skin for each area (evaluated using a scale from 0 to 4).

    Measured: From baseline to 3months

  2. Evaluation of Global Tolerance

    The investigator evaluates the tolerance using a 5-point skin reaction scale (0 represent No local intolerance ; 4 represent a Very severe signs or symptoms of intolerance)

    Measured: From 1month to 3 months

Secondary outcomes (4)
  1. Change in Investigator's Global Assessment (IGA)

    The investigator evaluates the severity of melasma using a 4-point scale (from 0 (cleared, almost cleared) to 3 (severe (markedly darker than the surrounding normal skin)).

    Measured: From baseline to3 months

  2. Change in Subject Global Assessment of Improvement (SGAI)

    The subject evaluates the change on a 6-point scale from -1 (worsened) to 4 (totally cleared).

    Measured: From 1month to 3 months

  3. Change of Quality of life

    Subjects evaluate about the impact of melasma on the quality of life. On a scale of 1 (not bothered at all) to 7 (bothered all the time), the subject's rate how they feel. MELAS Qol scores range from 7 to 70, with a higher score signifying worse quality of life.

    Measured: From 1month to 3 months

  4. Change of stigmatization evaluation

    Subjects evaluate about the impact of melasma on stigmatization evaluation. On a scale of 1 (not bothered at all) to 7 (bothered all the time), the subject's rate how they feel. MELAS Qol scores range from 7 to 70, with a higher score signifying worse quality of life.

    Measured: From 1month to 3 months

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?

Change in mMASI scoring (time frame: From baseline to 3months). The study lists 2 primary outcomes in all. 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 NCT06787846, 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 22 Jan 2025.
