Mohs Micrographic Surgery

Topical timolol, a β2-Adrenergic receptor (B2AR) antagonist, has demonstrated promise in wound healing over the past several years. The majority of the literature has evaluated the use of topical timolol to shorten wound healing time in chronic wounds of non-surgical etiologies. To date, there are no prospective randomized clinical trials evaluating the role of topical timolol for shortening wound healing time in acute open surgical wounds. Therefore, the purpose of this study is to determine whether or not topical timolol solution decreases time to wound healing in patients with defects after Mohs Micrographic Surgery (MMS) that cannot be closed with sutures and are left to heal by second intent. The research team also will look to determine if there is a difference in cosmesis of wounds treated with topical timolol compared to those treated with the standard of care. The present study will primarily focus on wounds in the distal lower extremity as these are most commonly left to heal by secondary intent

A multicenter, prospective, randomized controlled clinical trial assessing the efficacy of a novel cellular, acellular, matrix-like product (CAMP) plus standard of care versus standard of care alone in the management of post-mohs micrographic surgery defects.

The purpose of this research study is to evaluate the efficacy and safety of topical timolol 0.5% for secondary intention wound healing following 1) Mohs micrographic surgery, 2) standard surgical excision, OR 3) electrodesiccation and curettage (ED\&C). Please note that healing by secondary intention refers to when a wound heals naturally without surgical closure. To evaluate the efficacy of topical timolol 0.5%, 220 participants will be recruited. Participants will be placed into one of two groups: The treatment group or the control group. 1. The treatment group will receive a topical timolol 0.5% solution, which will be applied to their wound daily for 12 weeks. 2. The control group will receive standard care with the addition of hydrogel, which will also be applied to their wound daily for 12 weeks. During this 12-week period, both groups will be required to upload photos of their wound healing to their MyChart account at weeks 3, 6, 9, and 12. These photos will be reviewed by the investigator to assess wound healing. Re-epithelialization and earlier complete wound healing will be compared between both groups to determine the efficacy of topical timolol 0.5% solution compared to the standard of care.
