AlloSource30 enrolled

Overview

This is a prospective, histologic analysis of biopsied tissue obtained from participants who have undergone a pre-pectoral breast reconstruction or augmentation surgery with expander placement and AlloMend® Acellular Dermal Matrix. AlloMend® Acellular Dermal Matrix graft incorporation with surrounding native soft tissue using histological assays characterizing host cell infiltration, neovascularization, inflammation, and host replacement of ADM collagen will be studied.

The purpose of this study is to evaluate the incorporation of AlloMend® Acellular Dermal Matrix with native surrounding tissue by obtaining up to three, 1 cm diameter biopsies per breast. The samples will then be transported to AlloSource Research and Development Labs for slide preparation and histologic analysis. This study will be performed at one (1) clinical center in the United States.

Outcomes

Primary Outcomes

AlloMend® Acellular Dermal Matrix graft incorporation when used in a soft tissue application

The primary endpoint being evaluated in this study is AlloMend® Acellular Dermal Matrix graft incorporation when used in a soft tissue application. The endpoint will be analyzed from biopsied tissue samples taken during the exchange of expander to permanent breast implant using histological assays characterizing host cell infiltration, neovascularization, inflammation, and host replacement of ADM collagen.

Time frame: At expander/implant exchange surgery; typically 1-3 months post expander placement
