study of eb-001 in facial scar reduction

Conditions: Mohs Surgery

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.

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.
