Excellarate and Tissue Repair Company's GAM Technology

The Excellarate topical gel employs TRC's Gene Activated Matrix(TM) technology and is designed to provide localized and sustained cellular release of platelet-derived growth factor-BB protein (PDGF-BB). Sustained delivery of PDGF-BB directly at the wound site is believed to stimulate angiogenesis and granulation tissue formation through the recruitment and proliferation of cells such as monocytes, fibroblasts and endothelial cells, which are necessary for the stimulation of a variety of wound healing processes. A previous Phase 1/2 clinical trial showed that Excellarate appeared to be safe and well-tolerated and resulted in a high rate of complete wound closure.

Gene Activated Matrix(TM) (GAM) technology is designed to provide a therapeutic level of protein synthesis at a particular site in the body and can be used in soft tissue such as skin, ligament, tendons and cartilage, as well as hard tissue such as bone. The technology is distinctive in that it is an immobilized form of local gene delivery that allows for control of gene dispersion. GAM consists of a biocompatible matrix comprising a gene or DNA vector encoding a growth factor or other therapeutic protein. For tissue repair, the application method involves placement of a GAM gel directly onto a wound site. TRC's studies have shown that proliferative cells in the body can migrate into the GAM, take up the immobilized vector and gene and then transiently express the encoded therapeutic protein. Compared with topical applications of proteins, this in situ expression method significantly prolongs the local availability of therapeutic protein to the cells involved in tissue repair. TRC's GAM technology may have potential utility in several clinical indications where protein therapeutics have
