Idenix Pharmaceuticals Reports Second Quarter and Six Month 2013 Financial Results

CAMBRIDGE, Mass., Aug. 7, 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 second quarter ended June 30, 2013.

HCV Pipeline and Business Review

Samatasvir (IDX719), NS5A Inhibitor Program

  • In May 2013, Idenix initiated the phase II HELIX-1 12-week clinical trial evaluating an all-oral, direct-acting antiviral (DAA) HCV combination regimen of samatasvir (IDX719), Idenix's once-daily pan-genotypic NS5A inhibitor, and simeprevir (TMC435), a once-daily protease inhibitor jointly developed by Janssen R&D Ireland and Medivir AB. Treatment-naïve, non-cirrhotic, genotype 1b or 4 HCV-infected patients are enrolled in one of three treatment groups receiving 50, 100, or 150 mg samatasvir once-daily for 12 weeks in combination with simeprevir plus ribavirin.
  • The first cohort of patients (n=29) has completed enrollment. The Data Safety Monitoring Board has reviewed all data relating to this cohort up to 28 days of treatment and recommended that the study continue enrollment, which is now underway.
  • The treatment regimen has been well tolerated and there have been no treatment-related serious adverse events in the clinical trial to date.
  • Rates of sustained virologic response measured four weeks after the end of treatment (SVR4) will be available for the first cohort of patients in the fourth quarter of 2013.
  • A second trial (HELIX-2) of samatasvir, simeprevir and TMC647055, a once-daily non-nucleoside polymerase inhibitor boosted with low-dose ritonavir being developed by Janssen, is expected to begin enrolling genotype 1 or 4 treatment-naïve HCV-infected patients in the third quarter of 2013.

Nucleotide Inhibitor Program

  • In June 2013, Idenix announced a request from the United States Food and Drug Administration (FDA) for additional preclinical safety information for IDX20963, Idenix's lead uridine nucleotide prodrug candidate. Pending potential resolution of this request, the initiation of clinical testing of IDX20963 in the U.S. is on hold. Idenix has supplemental preclinical work ongoing and is compiling data to respond to the FDA's communication. The Company is simultaneously pursuing a clinical development strategy for IDX20963 outside the U.S.
  • Additionally, Idenix plans to file a regulatory submission to initiate clinical trials for a second uridine nucleotide prodrug inhibitor in the second half of 2013.

"In the second quarter, we saw significant progress of our lead HCV development program, samatasvir, and continue to be on track to report data from the first patient cohort in the fourth quarter of this year," said Ron Renaud, Idenix's President and Chief Executive Officer. "We remain committed to our HCV nucleotide franchise, and we are actively pursuing additional paths forward with the ultimate goal remaining the evaluation of an all-oral internally developed pan-genotypic combination regimen including samatasvir and a nucleotide inhibitor."

Second Quarter and Six Months Ended 2013 Financial Results

For the second quarter ended June 30, 2013, Idenix reported total revenues of $0.1 million, compared to total revenues of $1.4 million in the second quarter of 2012. The Company reported a net loss of $28.9 million, or $0.22 per basic and diluted share, for the second quarter ended June 30, 2013, compared to a net loss of $25.4 million, or $0.23 per basic and diluted share for the second quarter ended June 30, 2012.

For the six months ended June 30, 2013, Idenix reported total revenues of $1.0 million, compared to total revenues of $37.1 million for the six months ended June 30, 2012. The Company reported a net loss of $59.7 million, or $0.45 per basic and diluted share, for the six months ended June 30, 2013, compared to a net loss of $13.9 million, or $0.13 per basic and diluted share for the six months ended June 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 $4.7 million in research and development expenses and $6.1 million in general and administrative expenses mainly due to patent interference and litigation costs.

2013 Financial Guidance

At June 30, 2013, Idenix's cash and cash equivalents totaled $177.6 million. The Company continues to expect that its current cash and cash equivalents will be sufficient to sustain its operations into at least the second half of 2014. This guidance assumes no milestone payments or license fees, no reimbursement for development programs and no financing activities.
