Protein Polymer Technologies Reports Third Quarter 1999 Financial Results

    SAN DIEGO, Nov. 10 -- Protein Polymer Technologies, Inc. (Nasdaq: PPTI), reports today its financial results for the third quarter ended September 30, 1999.  For the quarter, the Company had a net loss applicable to common shareholders of $827,000 ($0.06 a share), versus a net loss of $1,529,000 ($0.14 a share) for the comparable period a year ago.  For the nine month period ended September 30, 1999, the net loss applicable to common shareholders was $3,243,000 ($0.26 a share) as compared to $7,662,000 ($0.73 a share) for the same period in 1998.  The net loss and loss per share amounts include accumulated and distributed dividends related to the Company's preferred stock.  The reduction in losses for both the three and the nine month periods was due primarily to cost cutting measures implemented during the quarter, and to the completion of preclinical studies and initial regulatory filings in preparation for beginning human clinical trials of the Company's injectable hydrogel implant for the treatment of female stress urinary incontinence, scheduled to start next month.
    Operating expenses for the quarter were $784,000 and $3,117,000 for the nine month period, as compared to $1,508,000 and $4,368,000 for the same periods in 1998.  The decrease was due primarily to planned cost cutting measures taken in the third quarter, and to reduced research and development expenses following the completion of preclinical testing and the filings associated with the Company's Investigational Device Exemption (IDE) obtained from the U.S. Food and Drug Administration (FDA) in May 1999.  The approved IDE requested permission to initiate human clinical trials of PPTI's injectable urethral bulking agent for the treatment of female stress urinary incontinence.
    PPTI's cash balance as of September 30, 1999 was $998,000.  At planned spending levels this amount is expected to meet the Company's anticipated capital requirements until February, 2000.
    The Company plans to raise additional funds for continuing operations through private or public offerings and collaborative agreements.  In addition, the Company is continuing to pursue other strategic alternatives. However, there can be no assurance that any of these fundings will be consummated in the necessary time frames needed for continuing operations or on terms favorable to the Company.  If adequate funds are not available, the Company will be required to significantly curtail its operating plans and may have to sell or license out significant portions of the Company's technology or potential products.
    "Our financial results for the quarter reflect a reduction in outside expenditures due to planned reductions in operating expenses and the completion of preclinical testing; additional development expenditures will be required for impending clinical testing and product registration with the FDA," said J. Thomas Parmeter, PPTI's President and Chief Executive Officer. "While our ability to proceed is entirely dependent on identifying additional sources of working capital, there is continued interest in our programs by potential partners, and we are currently pursuing a number of opportunities. We are in discussions with potential strategic partners for each of the soft tissue augmentation products, and in our redefined surgical adhesives and sealants program, we are seeking to create a partnering relationship for the development of a new injectable Spinal disc repair product for the treatment of lower back pain, although there is no assurance that these efforts will ultimately lead to a strategic alliance."
    Protein Polymer Technologies, Inc., is a San Diego-based company focused on developing products to improve medical and surgical outcomes.  From its inception in 1988, PPTI has been a pioneer in protein design and synthesis, developing an extensive portfolio of proprietary biomaterials.  These genetically engineered biomaterials are high molecular weight proteins, processed into products with physical and biological characteristics tailored to specific clinical performance requirements.  Targeted products include urethral bulking agents for the treatment of stress urinary incontinence, dermal augmentation products for cosmetic and reconstructive surgery, surgical adhesives and sealants, adhesive fillers for repair of Spinal discs, scaffolds for wound healing and tissue engineering, and depots for local drug delivery.
