Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This clinical trial studies whether a disposable negative pressure wound therapy (dNPWT) device, SNaP Wound Care System (Ultraportable Mechanically Powered Negative Pressure Wound Therapy) (SNaP), promotes wound healing in the lower limbs in patients that have undergone Mohs micrographic surgery (Mohs surgery) for non-melanoma skin cancer. Mohs surgery is a surgical technique used to treat skin cancer. Individual layers of cancerous tissue are removed and examined under a microscope one at a time until all cancerous tissue has been removed. It is an important part of removing skin cancer, but it often leads to soft-tissue defects and reconstructive challenges, especially in high-tension areas like the lower limbs. Typically, these wounds are managed by leaving them open and allowing them to heal from the base up or are reconstructed by transferring healthy skin from another part of the body. Negative pressure wound therapy (NPWT) is a wound dressing system that continuously or intermittently applies subatmospheric pressure to the surface of a wound to draw out fluid and promote healing. The SNaP device is a dNPWT device for lower leg wound healing designed for increased portability and ease of use outside of a hospital setting. It is a modification of traditional NPWT devices that uses springs to generate pressure, making it lighter and more user-friendly than traditional devices that rely on electrically powered pumps. This may be a more effective way to promote wound healing in the lower limbs following Mohs surgery for non-melanoma skin cancer.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVE:

I. To compare wound healing duration between the two groups, aiming to provide insights into the potential benefits of dNPWT for lower limb wounds in a clinical setting.

OUTLINE: Patients are randomized to 1 of 2 groups.

GROUP 1: Patients undergo dNPWT with SNaP device following standard of care (SOC) Mohs surgery and attend follow-up visits with re-application of SNaP device over 30 minutes once a week (QW), as needed until complete wound healing is achieved, for up to 12 weeks. Patients also receive education regarding SNaP device application and informational/educational SNaP device handouts on study.

GROUP 2: Patients undergo SOC wound care with non-adherent dressing following SOC Mohs surgery and attend follow-up visits with non-adherent dressing changes over 30 minutes QW, as needed until complete wound healing is achieved, for up to 12 weeks. Patients also receive education on SOC wound dressing changes on study.

After completion of study intervention, patients are followed up at week 12.
