Study of EB-001 in Facial Scar Reduction

Study Overview
=================
Brief Summary
-----------------
This study will evaluate the safety and efficacy of EB-001 in improving wound healing and reducing scar formation in patients undergoing Mohs surgery for skin lesions in the forehead area following a single treatment of EB-001 when injected into the muscles underlying the incision area.

Detailed Description
-----------------
This study will evaluate the safety and efficacy of EB-001 in improving wound healing and reducing scar formation in patients undergoing Mohs surgery for skin lesions in the forehead area following a single treatment of EB-001 when injected into the muscles underlying the incision area. The safety objective is to determine the safety and tolerability of single treatment of EB-001 when injected into facial muscles underlying a surgical wound during Mohs surgery. The efficacy objective is to evaluate the efficacy of a single treatment of EB-001 when injected into the facial muscles (frontalis) underlying the surgical wound in improving wound healing, and reducing scar formation.
