About this study

Official title: Evaluation of the Cutaneous and Ocular Tolerance of RV4857A Sunscreen Product and Its Efficacy Against the Recurrence of Lesions Post Sun Exposure in Subjects With Facial Acne

The aim of this study is firstly to assess the tolerance of the sunscreen RV4857A-CD2110 after 28 days and 57 days of at least a twice daily on the study areas, secondly to assess anti-imperfection efficacy after 28 days and 57 days of use and its efficacy against recurrence of acne lesions post-sun exposure.

Read the detailed description

This is a monocentric study on adults and adolescents with acne prone skin on the face. This open-labelled study aim first to assess the dermatological and ophthalmological tolerance of the investigational sunscreen product RV4857A formula CD2110 after 28 days and, dermatological tolerance after 57 days of at least a twice daily on the study areas, under normal conditions of use, on 40 subjects intending to have a minimum of 10 days per month of sun exposure duration ≥ 1h, in the time slot 11am-4pm and intending to have a minimum of 4 swimming sessions (sea or swimming pool) during at least the first month of the study.

Secondary objectives :

  • To assess the anti-imperfection efficacy of the product during the summer
  • To assess the "non" rebound effect (non recurrence of acne) one month after stopping the application of the sunscreen and without any sun exposure at D85 (difference between D85 and D0)
  • To evaluate the impact on Quality of Life of subjects through CADI and DLQI questionnaires (or CDLQI questionnaire for adolescent from 12 to 16 years-old) completed at baseline, D29 and D57

The study includes 4 visits :

  • Visit 1: Inclusion visit (D1)
  • Visit 2: Intermediate visit (D29)
  • Visit 3: Intermediate visit "end of summer" (D57), a Stop the application of the sunscreen product (and stop sun exposure) between Visit 3 and the end of the study Visit 4: End of study visit in autumn (D85)

The theoretical study duration for each subject will be 85 days with at least 57 days of product use. The study interest areas are Face and Neck.

Study groupRoleWhat they receive
RV4857A armApplication of the product before and during each sun exposure, at least twice a day. During sun exposures, the applications were renewed as often as necessary, in particular after swimming, perspiring, towelling, in order to ensure a good protection. On days of bad weather, the product was applied in the morning and at the beginning of the afternoon.

What is being measured

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

  1. Assessment of the dermatological physical signs

    The assessment of the dermatological physical signs is based on a visual examination

    Measured: Change from Baseline to 30 minutes after product application, to 29 and 57 days later

  2. Assessment of the dermatological functional signs

    The functional signs is assessed by questioning the subject

    Measured: Change from Baseline to 30 minutes after product application, to 29 and 57 days later

  3. Assessment of the ophthalmological physical signs

    The assessment of the ophthalmological physical signs is based on a dermatologist visual examination

    Measured: Change from Baseline to 30 minutes after product application, to 29 and 57 days later

  4. Assessment of the ophthalmological functional signs

    The functional signs is assessed by questioning the subject

    Measured: Change from Baseline to 30 minutes after product application, to 29 and 57 days later

  5. Assessment of the Tear film Break Up Time (BUT)

    The tear film break-up time is a test to measure the relative stability of the pre-corneal tear film. This examination is performed by the same Ophthalmologist thanks to a biomicroscope after blinking (using a chronometer). The measured time will be expressed in seconds

    Measured: Change from Baseline to 30 minutes after product application, to 29 and 57 days later

  6. Assessment of global tolerance assessment (dermatogical assesment), a 5-point scale

    • Excellent: no functional nor physical signs related to the investigational product observed or reported by the subjects
    • Very good
    • Good
    • Moderate
    • Bad

    Measured: Change from Baseline to 29 and 57 days later

    • Good
    • Moderate
    • Bad

    Measured: Change from Baseline to 29 days later

    by statistical comparison of open and closed comedones counted by the investigator on the face before and after 28 days of application of investigational product

    Measured: Change from Baseline to 29 days later

  5. Change of the acne severity, assess by Global Acne Evaluation (GEA) on a 6-point scale

    • 0: Clear
    • 1: Almost clear
    • 2: Mild
    • 3: Moderate
    • 4: Severe
    • 5 : Very Severe

    Measured: Change from Baseline to 29, 57 and 85 days later

  6. Evaluation of the global acne evolution on a 6-point scale

    -1: Worsening, 0: No change,

    1. Mild improvement,
    2. Moderate improvement,
    3. Good improvement,
    4. Very good improvement
