Protein Polymer Technologies, Inc. (PPTI), a development stage biotechnology company, engages in the research, development, production, and clinical testing of medical products based on its proprietary protein-based biomaterials and tissue engineering technology. It primarily focuses on developing technology and products to be used for soft tissue augmentation, tissue adhesives and sealants, wound healing support, and drug delivery devices. Through its proprietary technology, the company produces molecular weight polymers that can be processed into a variety of material forms, such as gels, sponges, films, and fibers. In addition, PPTI is developing an injectable product based on one of its patented silk-elastin polymers for use as a urethral bulking agent for the treatment of female stress urinary incontinence; an injectable dermal augmentation product, which is in pilot human clinical testing for the treatment of contour deficiencies due to aging and environmental exposure and disease, such as acne and cancer, and surgery; and an injectable protein-based formulation based on PPTI’s proprietary tissue adhesive technology for the repair of damaged or deteriorated spinal discs.
