CAMBRIDGE, Mass., May 1, 2014 (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 first quarter ended March 31, 2014.

HCV Pipeline Review

  • In April 2014, Idenix reported positive seven-day proof-of-concept data from a phase I/II clinical trial for IDX21437, the Company's lead uridine-based nucleotide prodrug candidate. The trial demonstrated that IDX21437 was well tolerated and exhibited potent pan-genotypic activity with mean maximal viral load reductions of 4.2 - 4.3 log10 IU/mL for treatment-naïve genotype 1, 2 and 3 HCV-infected patients in the highest dose group (300 mg) for seven days. Based on these findings, the 300 mg dose of IDX21437 has been chosen for an anticipated phase II combination study of IDX21437 with samatasvir, Idenix's pan-genotypic NS5A inhibitor. This phase II study is expected to initiate mid-2014.
  • Further, under a collaboration with Janssen Pharmaceuticals, Inc., Idenix is evaluating samatasvir, simeprevir and TMC647055/r in a phase II clinical program. HELIX-1 recently reported safety and sustained virologic response rate (SVR4) findings at a medical meeting, and HELIX-2 is expected to report SVR4 data in the second half of 2014. In this phase II program, samatasvir-containing regimens have been administered to more than 140 patients for 12-week treatment durations and have been safe and well tolerated to date.
  • Additionally, in April 2014, Idenix initiated enrollment for the healthy volunteer portion of a phase I clinical trial of IDX21459, a follow-on, uridine-based nucleotide prodrug candidate, in Europe. IDX21459 has shown a favorable preclinical profile including potent, pan-genotypic activity and favorable safety with respect to cardiac, mitochondrial and genotoxicity assessments.

"Idenix continues to make strong progress in advancing our multiple clinical trials with a key goal of initiating a combination study of IDX21437 with samatasvir for an all-oral pan-genotypic regimen for HCV," said Ron Renaud, Idenix's President and Chief Executive Officer. "The nucleotide prodrug/NS5A inhibitor combination could play a major role in HCV treatment due to a number of factors, including the scarcity of this combination, the potential to deliver the convenience of once-daily dosing with one pill, and the potential to be safe and potent with a high barrier to resistance and limited drug-drug interaction concerns. Importantly, we believe our combination has the potential to provide an additional treatment option for patients, physicians and payers in the evolving HCV landscape."

Registered Direct Offering

In January 2014, the Company issued 16.4 million shares of its common stock to Baupost Group, L.L.C. through a registered direct offering under a shelf registration and received $106.6 million in net proceeds.

First Quarter 2014 Financial Results

For the first quarter ended March 31, 2014, Idenix reported total revenues of $(3.0) million, compared to total revenues of $0.9 million in the first quarter of 2013. The Company reported a net loss of $34.1 million, or $0.24 per basic and diluted share, for the first quarter ended March 31, 2014, compared to a net loss of $30.8 million, or $0.23 per basic and diluted share for the first quarter ended March 31, 2013. In the first quarter of 2014, the Company recorded a charge against revenue related to the impact of the stock subscription rights of Novartis Pharma AG, which is described in more detail in the Company's quarterly report on Form 10-Q for the quarter ended March 31, 2014.

2014 Financial Guidance

At March 31, 2014, Idenix's cash and cash equivalents totaled $205.0 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 2015. This guidance assumes no milestone payments or license fees, no reimbursement for development programs and no financing activities.
