DESCRIPTION (provided by applicant): Seromas are a common post-operative complication particularly prevalent following ablative and reconstructive surgeries. Without timely intervention post-operative seromas can lead to significant patient morbidity including infection, tissue necrosis, permanent cystic cavities, reduced limb mobility and permanent disfigurement. The high incidence of seroma formation and the resulting increase in patient morbidity has led to the widespread use of drainage to treat seromaafter formation. The last several decades have also seen the development and implementation of several clinical and experimental preventative treatment strategies; however, to date no preventative strategy has shown clinically relevant efficacy and seromarates remain at unacceptably high levels. Consequently, there is a clear need for a clinically effective, preventative seroma treatment. The current STTR funded research effort will lay the foundation for the commercialization of a new class of biomaterialfor the prevention of seroma, thereby enhancing patient health through improved patient outcomes and reduced patient morbidity. Preliminary studies have shown that a novel coblock polymer in hydrogel form, consisting of a methoxy polyethylene glycol (MPEG) block and a block of the polycarbonate form of dihidroxyacetone (pDHA), has shown efficacy in preventing seroma formation. Through the completion of research and development tasks during Phase I/II efforts, a compelling data set will be compiled on thebiocompatibility, the efficacy and the mode of action of MPEG-pDHA in seroma prevention. This data set will support the entry of MPEG-pDHA into the FDA's regulatory process. A significant preliminary data set demonstrating the clinical utility of MPEG-pDHA hydrogels in seroma prevention has been developed. Key features of this biomaterial are: in vitro and in vivo biodegradation (within 24h in vitro and 3 das in vivo) into biocompatible products, and successful elimination of seroma in an accepted animal model of radical mastectomy. Phase I efforts will focus on determining the range of efficacy of MPEG-pDHA in vivo and on evaluating its biocompatibility using FDA accepted in vitro and in vivo biocompatibility testing standards. The key tasks are listed below: Task 1 - Synthesize and characterize the MPEG-pDHA polymers to be used during the Phase I study. Task 2 - Determine the range of efficacy in vivo using a model involving the harvesting of the rat latissimus dorsi muscle. Task 3 - Use FDA accepted ISO 10993 standards to quantify biocompatibility through in vitro cytotoxicity, genotoxicity, systemic toxicity, and hemocompatibility studies and local toxic effects after implantation through in vivo animal studies. PUBLIC HEALTH RELEVANCE: Seroma formation is a common post-operative complication that diminishes patient health and for which there are no accepted preventative treatments. The current STTR funded research effort aims to advance the development of a new biodegradable material for the prevention of seroma and thereby improve patient health through improved surgical outcomes.
