Trial Outcomes & Findings for Oleogel-S10 in Wound Healing of Inherited Epidermolysis Bullosa (BEB-10) (NCT NCT01294241)

NCT ID: NCT01294241

Last Updated: 2018-01-23

Results Overview

The primary end point was the progress of reepithelialization from baseline to either Day 14 ('recent wounds') or Day 28 ('chronic wounds') of the EB wound (half) treated with Oleogel-S10 and non-adhesive wound dressing (Mepilex®) intra-individually compared to the other wound (half) covered with non-adhesive wound dressing only (intra-individual comparison). Two independent experts were blind to treatment and assessed efficacy based on chronological series of cropped and coded photographs by wound (half) that were taken before start of treatment, during wound dressing changes and at the end of treatment on Day 14/Day 28. They evaluated each series and decided whether 1 wound (half) reepithelialized faster than the other ('winner'), or whether there was no difference in reepithelialization.

Participant Flow

Participants were enrolled from 03 Nov 2010 to 14 Jun 2011 at 1 center (University Medical Center Freiburg) in 1 country (Germany).

12 wounds in 10 participants (2 cycles of treatment in 2 participants) were treated with study medication. The reepithelialization was compared intra-individually in either 2 halves of an Epidermolysis bullosa (EB) wound ≥10 cm2 and ≤200 cm2 in size or in 2 EB wounds ≥5 cm2 in size, i.e. the total number of participants was 10 in the overall study.

PRIMARY outcome

Timeframe: 14 days for 'recent wounds', 28 days for 'chronic wounds'

Population: 12 wounds in 10 participants (intra-individual comparison, 2 cycles of treatment in 2 participants) were evaluated by assessors that were blind to treatment. 'Undecided' wounds that were either evaluated controversially (n=2) or as being equal (n=2) were excluded from the analysis of the primary efficacy variable.

The primary end point was the progress of reepithelialization from baseline to either Day 14 ('recent wounds') or Day 28 ('chronic wounds') of the EB wound (half) treated with Oleogel-S10 and non-adhesive wound dressing (Mepilex®) intra-individually compared to the other wound (half) covered with non-adhesive wound dressing only (intra-individual comparison). Two independent experts were blind to treatment and assessed efficacy based on chronological series of cropped and coded photographs by wound (half) that were taken before start of treatment, during wound dressing changes and at the end of treatment on Day 14/Day 28. They evaluated each series and decided whether 1 wound (half) reepithelialized faster than the other ('winner'), or whether there was no difference in reepithelialization.

All Study Participants
n=8 Wounds
Intra-individual comparison of two treatments: One half of an EB wound ≥10 cm2 and ≤200 cm2 in size or 1 EB wound ≥5 cm2 in size was treated with Oleogel-S10 and non-adhesive wound dressing. The other wound (half) was covered with a non-adhesive wound dressing only (Mepilex®) as standard of care control.
Non-adhesive Wound Dressing Only
The other half of an EB wound ≥10 cm2 and ≤200 cm2 in size or 1 EB wound ≥5 cm2 in size was treated with non-adhesive wound Dressing only as control.
Intra-individual Difference in Reepithelialization of Wound (Halves) at Day 14 in 'Recent Wounds' or Day 28 in 'Chronic Wounds'
Faster healing of wound treated with Oleogel-S10

SECONDARY outcome

Timeframe: Day 7±1

Population: As 2 participants received 2 cycles of treatment each, 12 wounds were treated with study medication.

The secondary endpoint was the intra-individual difference in median percentage of wound epithelialization at Day 7±1. Sizes of wound areas were measured using a digital wound evaluation program from the EB Center at the Department of Dermatology, University Medical Center Freiburg.
