(NASDAQ: EMIS) today announced results for the second quarter ended June 30, 2004. The Company also highlighted its progress in development programs using its proprietary eligen(R) drug delivery technology. Emisphere reported a net loss of $8.8 million, or $0.48 per share, for the quarter ended June 30, 2004, as compared to a net loss of $11.4 million, or $0.63 per share for the quarter ended June 30, 2003. Total operating expenses were $7.7 million for the 2004 second quarter, a decrease of $3.0 million, or 28%, compared to the same period last year. Total operating expenses include research and development costs of $3.7 million, a decrease of $1.7 million or 31%, compared to last year's second quarter. General and administrative expenses were $2.8 million, essentially equal to general and administrative expenses for the same period last year. Depreciation and amortization expenses were lower in the second quarter than last year due to the surrender of a portion of the leased space at the Tarrytown facility and the resultant reduction in the cost basis of leasehold improvements. For the quarter ended June 30, 2004, other expense, which includes investment income, interest expense and loss on sale of fixed assets, was $1.2 million compared to $0.9 million for the same period last year. Weighted average shares outstanding for the quarter ended June 30, 2004 and June 30, 2003, were 18.4 million and 18.0 million, respectively. As of June 30, 2004, Emisphere held cash, cash equivalents and investments totaling $30.2 million. Emisphere filed a shelf registration with the Securities and Exchange Commission on July 8, 2004, to sell in one or more offerings up to five million shares of its common stock. The Company plans to use the proceeds from the shelf offering for general corporate purposes, including further development of its lead clinical programs. Michael M. Goldberg, M.D., Chairman and Chief Executive Officer of Emisphere Technologies, Inc., commented, "We made significant progress during the second quarter in our research and development efforts, both internally and in collaboration with our partners. Our heparin program has advanced, and we are now preparing to initiate discussions with the U.S. Food and Drug Administration (FDA) for a new pivotal clinical trial comparing our soft gelatin capsule formulation with the current injectable treatment. In addition, other research programs we have undertaken, both with and without potential partners, have led to licensing discussions and new relationships with other major pharmaceutical companies. We consider these ongoing discussions and interest as validation of our proprietary eligen(R) technology." PRODUCT DEVELOPMENT UPDATE FOR SECOND QUARTER 2004 Oral Heparin During the second quarter, Emisphere initiated a clinical trial in the United States as part of its oral heparin program, with the purpose of selecting an oral solid formulation of unfractionated heparin (UFH), an antithrombotic/anticoagulant, for use in late-stage clinical trials. In a separate release issued today, the Company announced that it has selected a soft gelatin capsule formulation from the aforementioned trial to move forward into broad clinical testing. With this formulation, Emisphere plans to initiate discussions with the U.S. Food and Drug Administration (FDA) to outline an aggressive clinical development program, comparing the selected formulation with the currently marketed injectable low molecular weight heparin product. Oral Insulin On June 5th, Emisphere presented the results from a multiple-dose clinical study of an oral insulin tablet using its eligen(R) technology at the 64th Scientific Sessions of the American Diabetes Association. The study was conducted at PROFIL institute, an internationally recognized diabetes research center in Germany. The results from this study indicated that treatment with Emisphere's oral insulin over a fourteen day period was well-tolerated, led to improvements in post-prandial blood glucose concentrations and tended to improve fasting blood glucose concentrations and insulin resistance with no hypoglycemic events, an adverse complication that is often associated with injected insulin and other anti-diabetic treatments. Emisphere continues discussions with several potential partners for its oral insulin program while simultaneously continuing to advance the program's development. THE ELIGEN(R) TECHNOLOGY Emisphere's broad-based oral drug delivery technology platform, known as the eligen(R) technology, is based on the use of proprietary, synthetic chemical compounds, known as EMISPHERE(R) delivery agents, or "carriers". These molecules facilitate or enable the transport 2 of the therapeutic macromolecules across biological membranes such as those of the gastrointestinal tract, and exert their desired pharmacological effect. Emisphere's eligen(R) technology makes it possible to orally deliver a therapeutic molecule without altering its chemical form or biological integrity. ABOUT EMISPHERE TECHNOLOGIES, INC. Emisphere Technologies, Inc. (Nasdaq: EMIS) is a biopharmaceutical company pioneering the oral delivery of otherwise injectable drugs. Emisphere's business strategy is to develop oral forms of injectable drugs, either alone or with corporate partners, by applying its proprietary eligen(R) technology to those drugs or licensing its eligen(R) technology to partners who typically apply it directly to their marketed drugs. Emisphere's eligen(R) technology has enabled the oral delivery of proteins, peptides, macromolecules and charged organics. Emisphere and its partners have advanced oral formulations or prototypes of salmon calcitonin, heparin, insulin, parathyroid hormone, human growth hormone and cromolyn sodium into clinical trials. Emisphere has strategic alliances with world-leading pharmaceutical companies. For further information, please visit www.emisphere.com.
