(Nasdaq: ANDS), a biopharmaceutical company committed to advancing patient care by discovering, developing and commercializing novel small molecule, anti-infective medicines for the treatment of hepatitis C virus, hepatitis B virus and bacterial infections, today reported its financial results for the quarter ended March 31, 2004. "The first quarter of 2004 was very productive for Anadys. We continued to advance our clinical and pre-clinical programs surrounding the isatoribine family of compounds, including the continuation of the on-going clinical trial of isatoribine itself. Interim results of the isatoribine study have demonstrated proof of concept through hepatitis C virus reduction. In addition, we have initiated clinical trials of the first oral prodrug of isatoribine," said Kleanthis G. Xanthopoulos, Ph.D., Anadys' President and Chief Executive Officer. "The isatoribine family of compounds continues to be a significant focus of our development efforts. We are on track to nominate a second oral prodrug of isatoribine, with optimized pharmaceutical properties, during the second quarter of 2004. We also are advancing our discovery programs to continue building a pipeline of compounds for the treatment of HCV, HBV and antibacterial infections. Our achievements during the first quarter culminated in our initial public offering, which closed on March 31, 2004." RECENT HIGHLIGHTS - Anadys initiated a Phase I clinical trial of ANA971, its first oral prodrug of isatoribine. Anadys previously announced interim results from an on-going clinical trial of isatoribine which established proof of concept that a compound interacting with TLR-7 can reduce viral load in HCV infected patients. - Anadys exercised an exclusive option with LG Life Sciences ("LGLS") and entered into a joint development and license agreement with LGLS for the global development of ANA380 (LB80380), a compound for the treatment of HBV infection, which is currently in Phase II clinical trials. - Anadys announced the achievement of its first research milestone under its drug discovery collaboration with Amgen. - Anadys closed its initial public offering of common stock, raising gross proceeds of approximately $49 million. - Anadys and LGLS recently announced the completion of a Phase I/IIa clinical trial of ANA380 (LB80380), results of which provide further encouragement for the continued development of ANA380 (LB80380) as a therapy for chronic HBV infection. FINANCIAL RESULTS The Company reported revenues of $683,000 for the first quarter of 2004 compared to $562,000 for the first quarter of 2003. The net loss applicable to common stockholders was $7.6 million for the first quarter of 2004, compared with the net loss applicable to common stockholders of $7.7 million for the same period in the prior year. Basic and diluted net loss per common share was $3.77 in the first quarter of 2004, compared to $6.00 for the same period in 2003. Pro forma basic and diluted net loss per common share (assuming that the conversion of preferred stock to common stock that was automatically effected in conjunction with the IPO took place as of the original date of issuance) was $0.49 in the first quarter of 2004, compared to $0.56 for the same period in 2003. Cash, cash equivalents and securities available-for-sale totaled $51.1 million at March 31, 2004 compared to $14.5 million as of December 31, 2003, an increase of $36.6 million. This increase resulted primarily from our initial public offering of 6,250,000 shares of common stock for proceeds to us of $39.0 million, net of underwriting discounts and offering expenses. In addition on March 31, 2004, we closed the sale of an additional 215,000 shares of our common stock pursuant to the exercise by the underwriters of an over-allotment option which resulted in additional net proceeds to us of $1.4 million. Subsequent to March 31, 2004, we sold an additional 528,950 shares of common stock pursuant to the exercise by the underwriters of the over-allotment option, bringing the total net proceeds from the initial public offering to $43.9 million.
