CAMBRIDGE, Mass., Oct. 30, 2013 (GLOBE NEWSWIRE) -- 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 ended September 30, 2013.

HCV Pipeline Review

Nucleotide Inhibitor Program

  • IDX21437, a next-generation uridine nucleotide prodrug inhibitor, has received approval to enter clinical trials in Canada and Belgium. Idenix has initiated enrollment for the healthy volunteer portion of a phase I/II clinical trial. Extensive preclinical testing for IDX21437 demonstrated favorable antiviral activity across genotypes 1-6 and a safety profile which supported advancement into clinical trials.
  • Idenix is conducting additional preclinical work as requested by the United States Food and Drug Administration for IDX20963, a uridine nucleotide prodrug candidate.

Samatasvir (IDX719), NS5A Inhibitor Program

  • All patients (n=63) have completed enrollment in Part A of the phase II 12-week HELIX-1 clinical trial evaluating an all-oral, direct-acting antiviral (DAA) HCV combination regimen of samatasvir, Idenix's once-daily pan-genotypic NS5A inhibitor, and simeprevir, a once-daily NS3/4A protease inhibitor jointly developed by Janssen R&D Ireland and Medivir AB, and ribavirin in treatment-naive, non-cirrhotic, genotype 1b or 4 HCV-infected patients. SVR4 data for patients in Part A of the study are anticipated to be available in the fourth quarter of 2013. Part B of the ongoing HELIX-1 clinical trial includes exploratory cohorts which have been added to evaluate the safety and antiviral activity of a 25 mg dose of samatasvir in genotype 1b-infected patients and of a 100 mg dose of samatasvir in genotype 6-infected patients.
  • Idenix is planning to initiate a second 12-week phase II clinical trial in collaboration with Janssen Pharmaceuticals, Inc., HELIX-2, which will evaluate the 3-DAA combination of samatasvir, simeprevir and TMC647055, a once-daily NS5B non-nucleoside polymerase inhibitor boosted with low-dose ritonavir being developed by Janssen R&D Ireland, with and without ribavirin in genotype 1-infected patients who are either treatment-naive or have previously relapsed after treatment with pegylated interferon and ribavirin.

"A key objective for our development teams has been to commence a clinical trial for our nucleotide prodrug program this year," said Ron Renaud, Idenix's President and Chief Executive Officer. "Based on the differentiated profile we've seen in our preclinical research, we believe IDX21437 has strong potential to be a key component of a fixed-dose all-oral pan-genotypic regimen, specifically in combination therapy with our NS5A inhibitor."

Mr. Renaud continued, "We are also pleased with the progress of the phase II program for samatasvir. The ongoing HELIX-1 study is building the safety and antiviral efficacy profile for samatasvir as part of a 12-week all-oral treatment regimen and supporting future combination studies, including the 3-DAA HELIX-2 study, as well as the evaluation of a pan-genotypic combination with IDX21437 in 2014."

Third Quarter and Nine Months Ended 2013 Financial Results

For the third quarter ended September 30, 2013, Idenix reported total revenues of less than $0.1 million, compared to total revenues of $32.3 million in the third quarter of 2012. The Company reported a net loss of $34.0 million, or $0.25 per basic and diluted share, for the third quarter ended September 30, 2013, compared to a net income of $4.3 million, or $0.03 per basic and diluted share for the third quarter ended September 30, 2012.

For the nine months ended September 30, 2013, Idenix reported total revenues of $1.0 million, compared to total revenues of $69.3 million for the nine months ended September 30, 2012. The Company reported a net loss of $93.6 million, or $0.70 per basic and diluted share, for the nine months ended September 30, 2013, compared to a net loss of $9.7 million, or $0.09 per basic and diluted share for the nine months ended September 30, 2012. The change in net loss was mainly due to additional revenue as a result of the recognition of $36.1 million of deferred revenue in the first quarter of 2012 related to the termination of the license agreement with ViiV Healthcare Company. Additionally, there were increases of $12.9 million in research and development expenses mainly due to the advancement of our drug candidates and $8.5 million in general and administrative expenses mainly due to patent interference and litigation costs.

2013 Financial Guidance

At September 30, 2013, Idenix's cash and cash equivalents totaled $148.8 million. The Company continues to expect that its current cash and cash equivalents will be sufficient to sustain its operations through December 2014. This guidance assumes no milestone payments or license fees, no reimbursement for development programs and no financing activities.
