- Conditions
- Wound
- Interventions
- Device: Fibrillar collagen powder dressing
- Registration Number
- NCT03723577
- Lead Sponsor
- Medline Industries
- Brief Summary
Patients who meet the inclusion criteria will be provided with fibrillar collagen powder dressing. The powder dressing will be used in accordance with its label. After cleansing the wound by the clinical site staff, the powder is placed directly on the wound, and then the wound will be covered with an appropriate moisture retentive secondary dressing. Patients will visit the clinic twice a week to have the powder re-applied. Wound evaluations will take place once a week at the outpatient clinic, with the intervention lasting up to twelve weeks. Concurrent standard of care, such as compression for venous ulcers, will be provided.

- Primary Outcome Measures
Name Time Method Change in wound size over twelve week period Baseline to 84 days
- Secondary Outcome Measures
Name Time Method Change in Bates-Jensen Wound Assessment Tool Baseline to 84 days The Bates-Jensen Wound Assessment tool score will be used to assess the wound's status throughout the study. The Bates-Jensen Wound Assessment tool measures wound status. The wound size score ranges from 0 to 5. The wound depth score ranges from 0 to 5. The wound edge score ranges from 0 to 5. The wound undermining score ranges from 0 to 5. The necrotic tissue type score ranges from 1 to 5. The necrotic tissue amount ranges from 1 to 5. The exudate type score ranges from 1 to 5. The exudate amount score ranges from 1 to 5. The skin color surrounding wound score ranges from 1 to 5. The peripheral tissue edema score ranges from 1 to 5. The peripheral tissue induration score score ranges from 1 to 5. The granulation tissue score ranges from 1 to 5. The epithelialization score ranges from 1 to 5. The total score from these sub-scores added together is used as the total BWAT score. For all sub-score values, a value of 0 or 1 is a better outcome.
Change in reported pain level Baseline to 84 days The pain score will be recorded with a verbal numeric pain rating scale from 0-10.
