EXHIBIT 99.1 FOR IMMEDIATE RELEASE NASTECH ANNOUNCES FOURTH QUARTER AND 2003 FINANCIAL RESULTS -CASH AND INVESTMENTS GROWS 278% AND R&D SPEND GROWS 47% FROM PRIOR YEAR- BOTHELL, WA, MARCH 10, 2004 -- Nastech Pharmaceutical Company Inc. (Nasdaq: NSTK), today announced a net loss of $5.9 million, or $0.50 per share for the quarter ended December 31, 2003, compared to a net loss of $5.8 million, or $0.57 per share for the fourth quarter of 2002. Total revenue for the fourth quarter of 2003 was $911,000, a decrease of $846,000 from the fourth quarter of 2002. This decrease in revenue was partially offset by a $606,000 decrease in operating expenses. Comparing expenses in Q4-2003 to Q4-2002, research and development expense grew $2.3 million due to clinical trials and other expenditures in support of our R&D programs, general and administrative expense decreased $1.6 million and sales and marketing expense decreased $662,000. Net loss for the full year 2003 was $2.1 million, or $0.20 per share, compared to a net loss of $13.5 million, or $1.34 per share, for 2002. For 2003, total revenue was $19.4 million compared to $8.9 million for 2002. The increase in revenue for 2003 resulted primarily from a divestiture agreement with Pharmacia under which Nastech reacquired all rights to Apomorphine Nasal Spray for Sexual Dysfunction, and thereby recognized $16.3 million in connection with the divestiture and collaboration agreements, compared to $7.4 million related to the collaboration agreement in the same period of 2002. Nastech ended 2003 with $25.1 million in cash, cash equivalents and investments compared to $9.0 million at December 31, 2002. "During 2003 and early 2004, we accelerated our most advanced and nearest-term commercialization opportunities, including Calcitonin Nasal Spray for osteoporosis, Apomorphine Nasal Spray for sexual dysfunction, and PYY Nasal Spray for obesity," stated Steven C. Quay, M.D., Ph.D., Chairman, President, and Chief Executive Officer. "The significant improvement in our working capital as compared to the end of 2002 will help us achieve our near-term operating goals for these important programs." RECENT CORPORATE HIGHLIGHTS - PYY 3-36 Nasal Spray for Obesity In January 2004, Nastech initiated a Phase I-B dose-range finding study in overweight healthy subjects. Today, the Company announced the successful completion of this Phase I-B study. Results indicate that PYY significantly reduces appetite, and significantly reduces calorie intake both at the lunch meal 60 minutes after administration as well as for the entire 24-hour period. PYY administration was well tolerated, with an acceptable side effect profile. Detailed findings from this study will be discussed on today's conference call. - Apomorphine Nasal Spray for Sexual Dysfunction Today, Nastech announced that its Phase II Maximum Tolerated Dose clinical trial reached completion and the results identify a dose that is safe and well tolerated that is significantly above doses demonstrated in prior studies to produce efficacy in erectile dysfunction. The results of this study support moving forward with this sexual dysfunction clinical development program. Detailed findings from this study will be discussed on today's conference call. Nastech will seek a commercialization partner for this program before commencing Phase 3 clinical trials. - Calcitonin Nasal Spray for Osteoporosis Nastech's ANDA filing was accepted for review by the FDA in February 2004. Nastech is seeking a commercialization partner for this product. - Tight Junction and siRNA Technologies In February 2004, Nastech received a world-wide, non-exclusive license to the Fire et al. patents and patent applications titled "Genetic Inhibition by Double-Stranded RNA" (including U.S. Patent # 6,506,559 B1) from the Carnegie Institute of Washington, D.C. Nastech is using small interfering RNA (siRNA) technology in its tight junction research and to develop therapeutics based upon siRNA technology. The Company will discuss its research programs in these areas on today's conference call. CONFERENCE CALL INFORMATION Dr. Steven C.
