Primary Outcome Measures:
  • Local Tolerability Was Analyzed in Terms of Worst Score Post-Baseline. [ Time Frame: Week 4 ]
    Total Sum Score (TSS) is the sum of the 4 local tolerability scores for dryness, erythema, scaling and stinging/burning evaluated at each visit [None=0, Mild=1, Moderate=2 and Severe=3]. In consequence, it ranges from 0 [better outcome] to 12 [worse outcome]and was calculated for each study visit.
