2. Willing to comply with all study procedures and expects to be available for the duration of the study
3. Male and females ≥ 18 years of age and ≤ 75 years of age

   Types of burns include the following:

   • Scalding including from hot water, cooking oil, grease
   • Flame
   • Flash
   • Contact
5. Subjects who have staged surgical procedures planned e.g., one procedure to excise the burn injury and a later procedure to prepare the wound bed and apply an autologous skin graft.
6. The minimum total area across all lesions to have NovoSorb® BTM applied is 3% TBSA
7. Females, who are non-pregnant, naturally postmenopausal, or who agree to use effective contraceptive methods throughout the course of the study.

1. Has a known hypersensitivity to polyurethane
2. Only a non-burn injury has been experienced by the subject including soft-tissue degloving and friction burn/crush, i.e., road rash
3. Multiple traumas, i.e., significant traumatic injury to a solid organ in addition to skin
4. Presence of a medical condition with a life expectancy of less than 12 months, such as advanced malignancy
5. Presence of a medical condition that might interfere with treatment evaluation; or require a change in therapy including but not limited to, significant immune deficiency, or skin or vascular diseases in the area of the wound
6. For females - has known or suspected pregnancy, planned pregnancy, or during lactation
7. Has exposure to any other investigational agent within the last 6 months
8. Has exposure to any other treatment/device that will interfere with NovoSorb® BTM integration

9. Anticipated inability to perform wound care and follow-up procedures

   10. Anticipates of a level of non-compliance 11. The use of off-label treatments for full-thickness / deep-dermal burns is not

   permitted

   12. Clinical signs of wound infection at areas to be potentially treated using NovoSorb®

   BTM that in the opinion of the investigator may compromise safety and study objectives

   13. The use of NovoSorb® BTM on the face and in the perineum area is not permitted
