Exploratory Study to Evaluate the Efficacy of the Cosmetic Product RV3895A on Re-epidermised Scars Following Burns and Surgical Stitches in Adults, Adolescents and Children Over a 6-month Follow-up Period

This study is exploratory, non-comparative and open-label, conducted in France. It aims to provide insights into the effectiveness and safety of RV3895A - RY1774, potentially benefiting participants by improving scar appearance and quality of life.The aim of this study is to evaluate the efficacy of the cosmetic product RV3895A - RY1774 on re-epidermised scars of the face and body following burns and surgical stitches in adults, adolescents and children over a 6-month follow-up period.

Patients are divided into 2 groups:

• Group 1: adults with:
• Subgroup 1A: adults with post-burn scar(s)
• Subgroup 1C: adults with post-surgical scar(s) requiring stitches to be inserted and removed if applicable (in the case of non-absorbable stitches).
• Group 2: children and/or adolescents including children aged 2 to 7 years inclusive with:
• Subgroup 2A: children/adolescents with post-burn scar(s)

The study consists of 4 visits:

Visit 1: Inclusion (Day 1), Visit 2: Intermediate visit (Day 22), Visit 3: Intermediate visit (Day 85), Visit 4: End-of-study visit (planned or anticipated) (Day 169 )

INCLUSION CRITERIA :

• Male or female

  • For subgroups 1A and 2A: Located on the body and/or face
  • For sub-group 1C: Located on the upper limbs and/or neck and/or face
  • For group 1A: spread over an area less than or equal to 30% of the body surface area
  • For group 1C: spread over an area less than or equal to 15% of the body surface area
  • For group 2: spread over an area less than or equal to 10% of the body surface area
  • For sub-groups 1A and 2A: deep 2nd degree burns, whether grafted or not and/or in the 3rd degree graft(s) with limited cutaneous involvement and preservation of underlying structures
  • For sub-group 1C: post-surgical suture requiring stitches to be inserted and removed if applicable (case of non-absorbable stitches)

• Topical corticosteroid and/or immunosuppressants treatments applied on the studied scar(s) within 2 weeks before the inclusion visit or planned during the study
• Silicone-based scar treatment/product(s) applied within the wound healing phase to the studied scar(s)
• Any other scar care product(s) (emollient, etc.) applied on the studied scar(s) within the week before the inclusion visit*
