Protein Polymer Technologies Reports First Quarter 2001 Financial Results

    SAN DIEGO, May 15 -- Protein Polymer Technologies, Inc. (OTC Bulletin Board: PPTI), reports today its financial results for the first quarter ended March 31, 2001. For the quarter, the Company had a net loss applicable to common shareholders of $940,000 ($0.05 a share), versus a net loss of $548,000 ($0.04 a share) for the comparable period a year ago. The net loss, and the net loss per share amounts include accumulated dividends related to the Company's preferred stock.
    Contract and licensing revenue, and product and interest income totaled $92,000 for the first quarter ended March 31, 2001, compared to $403,000 for the same period last year. The decrease in contract and licensing revenue primarily represents the one time sale in the first quarter of last year of the Company's in vitro cell culture business to Sanyo Chemical Industries, Ltd. of Kyoto, Japan.
    Operating expenses for the quarter were $963,000, as compared to $882,000 for the same period in 2000. The increase in operating expenses was due to increased clinical start up costs and regulatory expenses stemming from the recent approval of the Company's Investigational Device Exemption by the U.S. Food and Drug Administration (FDA). The IDE approval allows the Company to initiate human clinical trials of its tissue augmentation agent for use in cosmetic surgery and dermatology to correct dermal contour deficiencies (facial lines, wrinkles, and scars) caused by aging or disease. Expenses are expected to continue to rise in subsequent quarters due to the increased expenditures for clinical testing and patient follow-up for both the dermal product, and for the continuing clinical trials of the Company's urethral bulking agent for the treatment of female stress urinary incontinence.
    PPTI's cash balance as of March 31, 2001 was $2,022,000. In combination with anticipated additional contract and license payments, and revenue projected for the delivery of clinical testing materials, this amount is expected to meet the Company's anticipated capital requirements until January 2002.
    "We are generally pleased with the Company's progress toward commercializing its tissue augmentation technology, but our ability to complete U.S. clinical testing of both the incontinence and the dermal product is dependent on identifying additional sources of working capital," said J. Thomas Parmeter, PPTI's President and Chief Executive Officer. "Over the course of the year, the Company may seek to raise additional funds for continuing operations through private or public offerings, and through additional collaborative agreements. In addition to our recent alliances with Genencor International to develop industrial applications of the technology, and with Spinal Wave, Inc. for the development of a new injectable Spinal disc repair product for the treatment of lower back pain, we are in discussions with other potential strategic partners for commercializing the soft tissue augmentation products."
