NCT05271708 - Explore the Short- and Mid-term Effects of Fespixon in Scar Cosmesis Following Cervical or Abdominal Surgery | Crick

Overview

The aim of this study is to evaluate the efficacy of the Fespixon cream for prevention and/or appearance reduction of different types of linear scars during the 12-week treatment phase, which is assessed by the blinded independent evaluator.

Methods: This study was designed as a prospective, double-blind, placebo-controlled trial involving 50 patients with linear scars. Bounded by the midpoint of the scar, each patient received a topical scar formulation consisting of fespixon cream on one side of scar, and placebo cream on the other side of scar. Treatment was given twice a day for 84 days. Assessments of the scars were performed at visit 1, 2, 3 following the onset of topical application using three methods: a clinical assessment using the Vancouver Scar Scale/ modified Vancouver Scar Scale, a photographic assessment to establish before and after treatment improvements, and at the end of the study period, patients completed a final satisfaction questionnaire.

Outcomes

Primary Outcomes

VSS total scores at Day 1 and Week 12 assessed by 3 blind evaluators

The VSS scores, assessed by 3 blind evaluators, changed from Day 1 to Week 12 will be used as an objective evidence.

Time frame: 12-week

Secondary Outcomes

mVSS individual scores at Day 1 and Week 12 assessed by a Principal Investigator

The mVSS scores, assessed by a Principal Investigator, changed from Day 1 to Week 12 will be used as an auxiliary evidence.

Time frame: 12-week

Hue feature-Red values via digital analysis at Day 1 and Week 12

1\. Using the data of Day1 as baseline, relative Δ ratio represents the difference of Δ ratio between Week 12 and Day1 out of baseline. NOTE1: Relative Δ ratio = (Week 12 Δ ratio - Day1 Δ ratio)/ Day1 Δ ratio NOTE2: Difference ratio= Δ ratio = Δ(scar-skin)/skin

1\. Using the data of Day1 as baseline, relative Δ ratio represents the difference of Δ ratio between Week 12 and Day1 out of baseline. NOTE1: Relative Δ ratio = (Week 12 Δ ratio - Day1 Δ ratio)/ Day1 Δ ratio NOTE2: Difference ratio= Δ ratio = Δ(scar-skin)/skin
