Protein Polymer Technologies Reports Fourth Quarter and Year End 1998 Financial Results

    SAN DIEGO, Mar. 9 -- Protein Polymer Technologies, Inc. (Nasdaq: PPTI), reports its financial results for the fourth quarter and year ended December 31, 1998.
    For the fourth quarter of 1998, the Company had a net loss applicable to common shareholders of $1,520,000, or $.14 per share, versus a net loss of $1,316,000, or $.13 per share, for the comparable period in 1997.  For the year ended December 31, 1998, the Company had a net loss applicable to common shareholders of $9,183,000, or $.88 per share, versus a net loss of $4,887,000, or $.52 per share, for the comparable period in 1997.  The difference in year end results is due primarily to a non-cash, "imputed dividends" expense that resulted from the sale and issuance of the Company's Series E Convertible Preferred Stock which raised $5.4 million in April and May of 1998.  Excluding the effect of the imputed dividends, the net loss applicable to common shareholders for 1998 would have been $5,638,000 ($.54 per share).
    Contract revenues, interest and product income totaled $74,500 for the fourth quarter of 1998, compared to $174,000 for the same period in 1997.  For the year, these revenues totaled $256,000, compared to $723,000 for the same period in 1997.  The decrease reflects reduced contract revenue in 1998. Operating expenses for the fourth quarter were $1,526,000, as compared to $1,419,000 for the same period in 1997.  Operating expenses for the year totaled $5,894,000, compared to $5,177,000 for the same period in 1997.  For both the fourth quarter and the year, the increased expenditures were due primarily to regulatory filings and preclinical testing in preparation for clinical trials of the Company's soft tissue augmentation products.
    As of December 31, 1998, the Company had $1,380,000 in cash and cash equivalents which the Company believes is sufficient to fund its operations through April, 1999.  The Company is pursuing a number of alternatives to meet the continuing capital requirements of its operations, such as collaborative agreements and equity financings.
   Last December, the Company filed with the U.S. Food and Drug Administration an Investigational Device Exemption ("IDE") for the use of its urethral bulking agent as a treatment for women suffering from stress urinary incontinence.  Approval of this IDE is required prior to beginning clinical trials.  In addition, the Company expanded its efforts toward filing an IDE in mid-1999 for use of its dermal bulking agent in cosmetic and reconstructive surgery applications.
   "Our financial results for both the fourth quarter and fiscal year reflect the necessary costs associated with bringing our soft tissue augmentation products to the clinic," said Dr. J. Thomas Parmeter, PPTI's President and Chief Executive Officer.  "We expect to continue to spend at this level or higher, to the extent capital is available, as we prepare to conduct clinical trials with our incontinence product later this year."
   "Our product pipeline is stronger and better defined than ever before," Dr. Parmeter added.  "Our bulking agents are ready for clinical trials, pending FDA approval, and we've directed the focus of our surgical adhesive technology toward the treatment of lower back pain through Spinal disc repair. We are currently in various stages of discussion with potential strategic partners for both our soft tissue augmentation products and our surgical adhesive product opportunities."
   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, scaffolds for wound healing and tissue engineering, and depots for local drug delivery.
