Study summary

The objective of this study is to evaluate the efficacy, cosmetic acceptability and improvement of the stigmatization of the tested product (2039125 03) used bis in die (BID) for 3 months in adult patients suffering from mild to moderate melasma, or mild to moderate acne induced post-inflammatory hyperpigmentation, or solar lentigo.

Read the detailed description

Hyperpigmentation is a common skin condition in which the colour of the skin becomes darker. These changes result from an excess of melanin production, distribution, or transport which can be caused by various internal and external factors such as genetic predisposition, hormonal changes, inflammation, acne, ultraviolet (UV) exposure.

Typical hyperpigmentation disorders include post-inflammatory hyperpigmentation, melasma and solar lentigines.

This open, single-centre, three-arm study is carried out with a new cosmetic formulation developed with the aim of acting on facial hyperpigmentation and used under normal conditions of use with before/after comparisons.

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:

  • Efficacy Analysis: in each group, the quantitative parameters are analyzed using a mixed-effect model. This model includes Time and baseline as fixed effects. Patient are added as random effect. The comparisons between post-baseline time-point and baseline are performed whatever the interaction results using a Dunnett adjustment. Degrees of freedom for the comparisons are approximated by the Kenward-Roger method.
  • 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 20 patients in each group was considered sufficient to meet the study objective.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • all phototypes
  • only one of the following pigmentary conditions on the face: epidermal or mixed, mild to moderate melasma; mild to moderate acne-induced PIHP; solar lentigo
  • female patient of must use one of the reliable methods of and agree not to change it during the study
  • patient agreeing not to be exposed to ultraviolet radiation (UV), natural (sun) or artificial (tanning salon), during the study

Exclusion criteria

Exclusion Criteria:

  • female patient who gave birth less than 3 months prior to Day 0, who is pregnant, breast-feeding or who plans to become pregnant during the study
  • male patient with beard or facial hair, which would interfere with clinical evaluation or clinical procedure baseline)
  • patient with any inflammatory dermatosis of the face such as seborrheic dermatitis, rosacea etc.
  • severe melasma, dermal melasma
  • patient with facial pigmentary disorders other than those described in inclusion criteria
  • patient who has used topical depigmenting agents such as hydroquinone and derivatives, glycolic acid, kojic acid, retinoids and derivatives, azelaic acid, niacinamide within 1 month prior to Day 0/Baseline visit
  • patient who has used systemic treatments such as tranexamic acid and oral melatonin within 1 month prior to Day 0/Baseline visit;
  • patient who has used drugs inducing pigmentation such as tetracyclines, fluoroquinolones, antiepileptics within 1 month prior to Day 0/Baseline visit
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

Primary outcomes

  1. IGA score for patients with melasma or acne induced post-inflammatory hyperpigmentation (PIHP)

    the hyperpigmentation is measured on a scale from 0 (cleared, almost cleared) to 3 (severe (markedly darker than the surrounding skin)

    Time frame: from baseline to Day84

  2. modified Melasma Area and Severity Index (mMASI) for patients with melasma

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

    Time frame: from baseline to Day 84

  3. Post-Acne Hyperpigmentation Index (PAHPI)

    The PAHPI total score is the sum of all 3 weighted scores: median lesion size (from 2 \[\< 3mm\] to 8 \[\> 10 mm\], median lesion intensity (from 3 \[slightly darker than surrounding skin,\] to 9 \[significantly darker than surrounding skin\] and number of lesions (from 1 \[1-15\] to 5 \[\> 60\]. Total score ranges from 6 to 22.

    Time frame: from baseline to Day 84

  4. solar lentigo pigmentation scale

    the solar lentigo pigmentation scale evaluates the pigmentation using the following scale: from 0 (no pigmentation) to 10 (brown+).

    Time frame: from baseline to Day84

Secondary outcomes

  1. colorimetry measures

    Skin color is measured using the L\*a\*b\* color space (L\* represents lightness, a\* its position between green and red, b\* its position between blue and yellow).

    Time frame: from baseline to Day84

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jun 2024 (actual). Primary completion is estimated for Mar 2025, 9 months after the start.

Of 27 industry-sponsored interventional studies with no phase under Hyperpigmentation, half reached primary completion within 3 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 10. This study's planned 9 months is above that.

Counting every sponsor, half of 64 studies reached it within 7 months; a quarter within 3 and three quarters within 25.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 6, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
