PRESS RELEASE: Nastech Pharmaceutical Company Says to Cut Workforce

Nastech Pharmaceutical Company Says to Cut Workforce

BOTHELL, Wash., Nov. 13 -- Nastech Pharmaceutical Company Inc. ("Nastech") (Nasdaq: NSTK - News) announced today its corporate restructuring initiatives aimed at reducing operating expenses and enhancing shareholder value. Nastech will seek to establish its subsidiary, MDRNA, Inc., as an independent, separately financed company as was announced today, and will concentrate on Phase 2 clinical and partnered programs as well as cost containment strategies for the near-term.

"The steps that Nastech is taking will better position the Company to achieve our near-term goals as well as reduce our operational expenses while ensuring that we retain our key capabilities for long-term growth," stated Steven C. Quay, M.D., Ph.D., Chairman, President and CEO of Nastech. "The establishment of MDRNA as an independent company will better serve our shareholders by providing a structure that will help unlock the value of Nastech's RNAi assets as well as expedite the development of new therapeutics based on this exciting new technology. Furthermore, by having Nastech concentrate on our core drug delivery technologies and our most advanced clinical programs it will enable us to make the greatest progress with the resources that are available."

First, Nastech plans to concentrate its resources on its Phase 2 clinical development programs that are currently ongoing or planned including PYY3-36 Nasal Spray for obesity, Insulin Nasal Spray for type 2 diabetes, and PTH1-34 Nasal Spray for osteoporosis.

Secondly, as announced today, Nastech will move forward with the process of establishing MDRNA as an independent company. The new structure will give Nastech the ability to pursue independent investment to fund MDRNA's operations. Nastech plans to pursue such funding in the near-term, subject to market conditions, and expects to retain significant ownership in MDRNA following such financing. In addition, Nastech intends, subject to change based on market conditions or future change in strategy, to thereafter issue a dividend to Nastech's shareholders of a portion of the MDRNA equity held by Nastech, and to effect the public trading of those securities through a Form 10 filing.

The planned change in corporate structure will enable Nastech to continue its focus on the development of peptide and protein drug delivery technologies while better positioning MDRNA for strategic alliances and direct investment as it develops RNAi therapeutics targeting a broad range of diseases. The establishment of MDRNA as an independent company will also allow it to be better compared and valued relative to other companies in the field of RNAi therapeutics.

Finally, Nastech is implementing a workforce reduction plan as soon as feasible to align with the Company's development and clinical plans, which will help to conserve cash, cash equivalents and investments which as of September 30, 2007 were $58.1 million.
