Trial Outcomes & Findings for Investigation of the Clinical Performance of Biatain Fiber Ag on Venous Leg Ulcers (NCT NCT05873257)

NCT ID: NCT05873257

Last Updated: 2025-06-03

Results Overview

Wound area will be measured by obtaining photos of the wounds and measure these afterwards. A planimetric software will be used where the wound is photographed with a ruler of known dimensions placed at the skin near the wound edge and the image is transferred to a computer and opened in the planimetric software. The ruler is used for calibration of linear dimensions at the image. Once the wound border is manually traced with a computer mouse the area of wound is calculated and displayed.

PRIMARY outcome

Timeframe: 4 weeks

Population: The primary analysis was based on subjects exposed to investigational device and with reliable baseline assessment of wound area. One subject was omitted (entire wound not captured on photo at baseline). The last observation 'on-treatment' was used in the analysis. The sensitivity analysis was conservatively based on the entire ITT population also including a subject with an unreliable wound area assessment at baseline. The analysis was performed as the primary analysis.

Wound area will be measured by obtaining photos of the wounds and measure these afterwards. A planimetric software will be used where the wound is photographed with a ruler of known dimensions placed at the skin near the wound edge and the image is transferred to a computer and opened in the planimetric software. The ruler is used for calibration of linear dimensions at the image. Once the wound border is manually traced with a computer mouse the area of wound is calculated and displayed.
