Clinical Trial Summary

This study seeks to demonstrate the performance of Negative Pressure Wound Therapy on chronic wounds such as diabetic foot ulcers and venous leg ulcers.

Description:

This study seeks to demonstrate the performance of Negative Pressure Wound Therapy on chronic wounds such as diabetic foot ulcers and venous leg ulcers. The primary objective of the study is to demonstrate the performance and safety of Avelle Negative Pressure Wound Therapy on wound and wound fluid management when used in accordance with the instructions for use. Participation in the study is anticipated to be two weeks. The Avelle™ NPWT System will be used for two weeks and participants will be seen for study visits during this time. Study participants will need to visit the doctor's office up to five times and, at a minimum, will be required to see the health care provider three times, dependent on the condition of the wound. Each visit is anticipated to last for approximately 45 to 60 minutes.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The reduction in wound size of the target wound between baseline and end of study	Area reduction will be assessed by measuring the wound area at Day 0, Day 6 (+/- 1 day), and Day 7 (+/- 1 day)	14 days
Secondary	Wound Healing Status	Assessment of wound progression between baseline and 14 day visit. Wounds will be assessed as healed or progressing towards healing by the investigator.	14 days
Secondary	Assessment of Skin	Assessment of condition of surrounding skin and signs of infection around the wound using a standardized wound assessment tool (as captured within study database)	14 Days
Secondary	Rate of Device Related Adverse Events	Assessment of rate of device related adverse events (ADE) associated with the dressings	14 days
