Idenix Pharmaceuticals, Inc. Reports Third Quarter and Nine Month 2011 Financial Results and Provides Pipeline Update

CAMBRIDGE, Mass., Nov. 2, 2011 /PRNewswire/ -- Idenix Pharmaceuticals, Inc. (NASDAQ: IDIX), a biopharmaceutical company engaged in the discovery and development of drugs for the treatment of human viral diseases, today reported unaudited financial results for the third quarter and nine months ended September 30, 2011. At September 30, 2011, Idenix’s cash and cash equivalents totaled $64.7 million.

Third Quarter and Nine Month 2011 Financial Results
For the third quarter ended September 30, 2011, Idenix reported total revenues of $2.6 million, compared to total revenues of $3.8 million in the third quarter of 2010. The Company reported a net loss of $11.7 million, or a loss of $0.12 per basic and diluted share, for the third quarter ended September 30, 2011, compared to a net loss of $12.9 million, or a loss of $0.18 per basic and diluted share for the third quarter ended September 30, 2010.

For the nine months ended September 30, 2011, Idenix reported total revenues of $7.7 million, compared to total revenues of $7.8 million in the nine months ended September 30, 2010. The Company reported a net loss of $33.9 million, or a loss of $0.39 per basic and diluted share, for the nine months ended September 30, 2011, compared to a net loss of $45.4 million, or a loss of $0.65 per basic and diluted share for the nine months ended September 30, 2010. The $11.5 million reduction in net loss in 2011 was due primarily to $5.5 million of lower expenses related to devoting fewer resources to our protease inhibitor and non-nucleoside polymerase inhibitor programs during 2011, $3.1 million lower salaries and personnel related costs, $2.6 million of lower costs related to the timing of clinical trials of IDX184 and $2.2 million of non-recurring restructuring expenses in 2010. Offsetting these amounts was an increase of $3.7 million in expenses related to the preclinical development of our NS5A drug candidates.

2011 Financial Guidance
The Company expects that its current cash, cash equivalents and the anticipated royalty payments associated with product sales of Tyzeka®/Sebivo® (telbivudine) will be sufficient to satisfy its cash needs into at least the second quarter of 2012. This guidance assumes no additional milestone payments, license fees, reimbursement for development programs and no financing activities.

Operational Highlights

IDX184 Program
The Company’s lead program, IDX184, is a pan-genotypic oral nucleotide polymerase inhibitor that has shown potent antiviral activity in both preclinical and clinical studies. IDX184 is a proprietary liver-targeted prodrug of 2'-methyl guanosine monophosphate with a high barrier to resistance in vitro.

In July 2011, the Company initiated enrollment of 100 HCV-infected patients into a 12-week Phase IIb clinical trial of IDX184 in combination with pegylated interferon and ribavirin. The Company will report an interim analysis from this study after the first 30 patients have completed 28 days of treatment. The Company initiated dosing of the first 20 patients, and is currently enrolling the remaining ten patients. There have been no safety signals to date. Based on the current rate of enrollment, the Company expects to complete one month dosing of the first 30 patients in December 2011, and anticipates releasing interim one month safety and antiviral activity data for the first 30 patients from the Phase IIb trial early in the first quarter of 2012.

Discovery Programs
IDX719, the Company’s lead NS5A inhibitor candidate, has shown potent and broad genotypic activity. The Company expects to submit regulatory filings by year end 2011 and begin the clinical program in early 2012.

The Company’s novel nucleotide program continues to make significant progress and has generated many preclinical compounds. Given the progress of the Company’s nucleotide prodrugs, the Company is reallocating discovery and development resources from its protease inhibitor program to the nucleotide program. The Company will continue to evaluate potential partnerships and licensing agreements for its protease inhibitor drug candidates and related intellectual property.
