Anadys Pharmaceuticals, Inc. Reports Fourth Quarter and Year-End 2010 Financial Results and Highlights

SAN DIEGO, March 3, 2011 /PRNewswire/ -- Anadys Pharmaceuticals, Inc. (Nasdaq: ANDS), a biopharmaceutical company dedicated to improving patient care by developing novel medicines for the treatment of hepatitis C, today reported its program highlights and financial results for the fourth quarter and year ended December 31, 2010.

"As we begin 2011, we believe Anadys is well-positioned to create value in the evolving HCV landscape," said Steve Worland, Ph.D., President and CEO of Anadys. "Last year, we demonstrated important safety and efficacy parameters for ANA598 in combination with current treatment over twelve weeks. We look to extend these results with the recently initiated Phase IIb study which should set the stage for Phase III development. Additionally, we plan to advance ANA773, our oral interferon inducer being developed as a pan-genotypic agent for HCV."

Development Program Highlights

ANA598

• Phase IIb Study Underway Dosing has begun in the Phase IIb study of ANA598 in combination with pegylated interferon and ribavirin (SOC) for the treatment of chronic hepatitis C (HCV). ANA598, the Company's direct-acting antiviral (DAA), is being tested in both treatment-naive patients and patients who failed a prior course of therapy with interferon and ribavirin. Approximately 275 patients are expected to be enrolled in the study. The primary endpoint of the study is Sustained Virological Response 24 weeks after patients complete treatment, known as SVR24.
• 2011 Milestones The Company expects to receive Week 8 antiviral response data for treatment-naive patients by the end of the second quarter of 2011, Week 12 antiviral response data for treatment-experienced patients in the third quarter of 2011 and Week 24 antiviral response data for both groups in the fourth quarter of 2011.

ANA773

• Planned Phase IIa Study In late 2010 the Company announced plans to resume development of ANA773 in HCV as a complement to DAAs in potential all oral regimens. The next planned study is a 28-day study of ANA773, in combination with ribavirin in the first cohorts and as triple therapy in combination with ribavirin and a DAA in subsequent cohorts. Anadys intends to conduct this Phase IIa study of ANA773 in Europe and expects that up to approximately 75 patients will participate in the trial, inclusive of the DAA cohorts. ANA773 is the Company's oral, small-molecule inducer of endogenous interferons that acts via the TLR7 pathway.
• 2011 Anticipated Milestones Anadys intends to commence the ANA773 28-day study during the second quarter of 2011 and expects to receive 4 week viral load data for ANA773 plus ribavirin in the fourth quarter of 2011.

Financial Results and Highlights

As of December 31, 2010, Anadys' cash, cash equivalents and securities available-for-sale totaled $38.0 million compared to $20.5 million as of December 31, 2009. The increase in cash, cash equivalents and securities available-for-sale reflects the receipt of net proceeds of $34.7 million from the Company's completed equity financings in June and October of 2010, partially offset by the Company's cash utilization during the year to fund operations.

Total operating expenses were $4.5 million for the fourth quarter of 2010, compared to $5.6 million for the fourth quarter of 2009. Included as a component of operating expenses were non-cash, share-based expenses of $0.3 million and $0.4 million for the fourth quarter of 2010 and 2009, respectively.

Research and development expenses were $2.8 million for the fourth quarter of 2010, compared to $4.0 million for the fourth quarter of 2009. Included as an offset to research and development expenses in the fourth quarter of 2010 is a $0.5 million grant Anadys was awarded under the U.S. government's Qualifying Therapeutic Discovery Project program. The remaining decrease was primarily attributable to a $0.5 million decrease in ANA598 development costs and a $0.4 million decrease in ANA773 development costs.

General and administrative expenses were $1.7 million for the fourth quarter of 2010, compared to $1.6 million for the fourth quarter of 2009. The general and administrative expenses were relatively consistent for the fourth quarter of 2010 when compared to the fourth quarter of 2009.

Anadys' net loss was $2.4 million for the fourth quarter of 2010, compared to a net loss of $4.3 million for the fourth quarter of 2009. Included in the net loss for the fourth quarter of 2010 is a $2.0 million gain resulting from a decrease in the Company's common stock warrant liability from September 30, 2010 to December 31, 2010. The liability is associated with warrants that were issued in connection with our "registered direct" offering in June 2009. Basic and diluted net loss per common share was $0.04 in the fourth quarter of 2010, compared to $0.11 in the fourth quarter of 2009.

For the twelve months ended December 31, 2010, Anadys reported a net loss of $16.3 million, compared to $27.3 million for the twelve months ended December 31, 2009. Basic and diluted net loss per common share was $0.38 and $0.81 for the twelve months ended December 31, 2010 and 2009, respectively.

2010 Data Presentations

• AASLD 2010, Oral Presentation results through 12 weeks from a Phase IIa study of ANA598 were reported. ANA598 added to SOC accelerated the rate of viral clearance, with comparable response at ANA598 doses of 200 mg bid and 400 mg bid. ANA598 also showed an excellent resistance profile and safety profile through 12 weeks of dosing in the study, with reported adverse events being typical for patients treated with interferon and ribavirin alone, although conclusions regarding safety cannot be made until results in more patients over longer duration are known. Positive preliminary SVR data were also presented.
• AASLD 2010, IL28B Poster data showed that the addition of ANA598 to SOC has the potential to confer beneficial effect on HCV patients regardless of IL-28B genotype.
• EASL 2010 and ICAR 2010, Preclinical Posters presented data showing enhancedantiviral activity and suppression of resistance when ANA598 is combined in vitro with other anti-HCV agents that act through diverse mechanisms, including protease inhibition, polymerase inhibition (both nucleoside and non-nucleoside inhibitors) and cyclophilin inhibition (a host target).
