A randomised, open-label, parallel-group, multicentre, comparative study to compare the efficacy and safety of Exufiber® with Aquacel® Extra™ dressings in exuding venous and mixed aetiology leg ulcers.

The performance and safety of Exufiber® gelling fibre and Aquacel® Extra™ Hydrofiber® wound dressings were compared for the management of chronic, exuding leg ulcers. The 6-week study (≤ 24 weeks in a subgroup of subjects) was a randomised, open-label, parallel-group, multicentre, non-inferiority design. Adults (n = 248, 30-97 years of age) were randomised to either Exufiber® or Aquacel® Extra™ dressing. The dressings were applied at baseline and evaluations of wound condition and performance of the dressing were recorded at 1, 2, 3, 4, and 6 weeks. The primary efficacy endpoint was the percentage reduction in wound area at 6 weeks relative to baseline, in the per protocol (PP) population. A median relative reduction of 50% for Exufiber® (n = 100) vs 42% for Aquacel® Extra™ (n = 107) was demonstrated in the PP population (P = 0.093) and confirmed in the intention-to-treat population. As the mean and 95% confidence interval for the difference in relative wound area reduction between groups at 6 weeks was -29.4% (-63.5; 3.2), and the lower limit did not exceed 12%, non-inferiority of Exufiber® was concluded. Both dressings were well tolerated and no safety concerns were identified in both groups. Clinicians' satisfaction with the dressings was higher for Exufiber® than for Aquacel® Extra™ in terms of ease of use and management of exudate, slough, and blood.
