PRESS RELEASE: Anadys Pharmaceuticals, Inc. to Cut Jobs, End Hepatitis B Drug Development

Anadys Pharmaceuticals, Inc. to Cut Jobs, End Hepatitis B Drug Development

SAN DIEGO, Aug. 1 -- Anadys Pharmaceuticals, Inc. , a biopharmaceutical company committed to the development and commercialization of novel medicines for the treatment of hepatitis C virus (HCV) infection and cancer, today reported its financial results for the second quarter ended June 30, 2007 and announced a strategic restructuring and refocusing.

"In response to the decision to discontinue the development of ANA975 for the treatment of hepatitis C virus infection, announced last week, we have restructured the Company to focus on our two key compounds that we believe have the highest commercial potential, ANA598 for hepatitis C and ANA773 for cancer," said Lawrence C. Fritz, Ph.D., president and chief executive officer of Anadys. "With our cash balance of $69 million, we believe we have the resources to carry these two compounds forward to achieve meaningful clinical milestones."

Strategic Restructuring

In connection with the decision to discontinue the development of ANA975, Anadys has undertaken a strategic restructuring comprising the following elements:

-- Focus its resources on the development of ANA598, a direct antiviral compound for the treatment of hepatitis C, and ANA773, a TLR7 agonist prodrug for cancer; -- Discontinue further development of ANA380, a nucleotide analog for the treatment of hepatitis B virus (HBV) infection, with all rights to this compound returning to LG Life Sciences; -- Halt all work on early discovery projects; and -- Effect an immediate reduction in force of 1/3 of the Company's employees.

The organization will retain a strong preclinical and clinical development infrastructure, core chemistry capabilities and a streamlined administrative staff. The Company expects that the reduction in force will generate annual savings of between $4 and $5 million. The Company will incur a one-time cash charge of approximately $0.8 million as part of severance arrangements.

About ANA598 and ANA773

ANA598 was nominated by Anadys in June 2007 for clinical development as an orally-administered direct antiviral for the treatment of HCV infection. ANA598 is a small-molecule, non-nucleoside inhibitor of the NS5b polymerase. Anadys plans to file an IND for ANA598 in the first half of 2008. ANA773, an oral TLR7 agonist prodrug, is in development as an oral therapy for the treatment of certain cancers. Anadys plans to file an IND for ANA773 in the second half of 2007.

"By restructuring, Anadys will be able to focus on the development of ANA598 and ANA773, wholly-owned development assets that we believe are attractive and exciting opportunities," said Dr. Fritz. "Our new streamlined organization is designed to optimize the efficient use of our solid cash position and enable us to achieve key clinical milestones that we believe are attainable in the next 12 to 18 months."

Financial Results

Anadys reported revenues of $1.3 million for the second quarter of 2007, compared to $1.6 million for the second quarter of 2006. Revenues for the quarter were primarily derived from the amortization of the $20 million up-front payment and the $10 million IND milestone payment each of which were received from Novartis during 2005. Operating expenses were $9.3 million for the quarter, compared to $9.8 million for the second quarter of 2006. This decrease was primarily attributable to a decrease in development costs associated with ANA975 which was placed on clinical hold in June 2006, partially offset by an increase in pre-clinical development costs associated with ANA598, a small-molecule, non-nucleoside inhibitor of the NS5b polymerase. Included as a component of Anadys' operating expenses was non-cash share-based expense of $1.0 million and $1.5 million for the three months ended June 30, 2007 and 2006, respectively.

Net loss was $7.0 million for the second quarter of 2007, compared to $7.1 million for the second quarter of 2006. Basic and diluted net loss per common share was $0.24 in the second quarter of 2007, compared to $0.25 for the same period in 2006. Non-cash share-based expense resulted in a $0.04 and $0.05 increase in basic and diluted net loss per share for the three months ended June 30, 2007 and 2006, respectively.

Revenues for the six months ended June 30, 2007 were $2.4 million compared to $3.1 million for the same period in the prior year. Revenues for the six months ended June 30, 2007 were primarily attributed to the amortization of the $20 million up-front payment and the $10 million IND milestone payment each of which were received in 2005. For the six months ended June 30, 2007, Anadys reported a net loss of $13.7 million compared to $12.9 for the same period last year. Basic and diluted net loss per common share was $0.48 for the six months ended June 30, 2007, compared to $0.45 for the same period in 2006.

As of June 30, 2007, the Company's cash, cash equivalents and securities available-for-sale totaled $68.8 million.
