Clinical Trial 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.

Description:

Hyperpigmentation is a common skin condition in which the color 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 (i.e. 60 patients in total) was considered sufficient to meet the study objective.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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 (markedly darker than the surrounding normal skin).	from baseline to Day84
Primary	modified Melasma Area and Severity Index (mMASI) for patients with melasma	the mMASI is calculated using 3 components: four regions (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 6).	from baseline to Day 84
Primary	Post-Acne Hyperpigmentation Index (PAHPI)	The PAHPI total score is the sum of all 3 weighted scores: median lesion size (form 2 [< 3mm] to 8 [> 10mm], 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.	from baseline to Day 84
Primary	solar lentigo pigmentation scale	The solar lentigo pigmentation scale evaluates the pigmentation using the following scale: from 0 (no pigmentation) to 10 (brown+).	from baseline to Day84
Secondary	colorimetry measurements	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).	from baseline to Day84
Secondary	stigmatization questionnaire	The patients are asked to answer the 17 questions of the stigmatization questionnaire using six different responses: very often, often, sometimes, rarely, never, not concerned.	from baseline to Day84
Secondary	local tolerability assessment by the investigator	The clinical signs (erythema, dryness and desquamation) are evaluated using 5-point rating scales: from 0 (no signs of irritation (no erythema/dryness/desquamation)) to 3 (severe signs of irritation (erythema/dryness/desquamation)).	Day28; Day56; Day84
Secondary	local tolerability assessment by the patient	the subjective symptoms (itching/tingling/burning sensation) are evaluated using 5-point rating scales: from 0 (no itching/tingling/burning sensation) to 3 (severe itching/tingling/burning sensation).	Day28; Day56; Day84
