News Release - July 13, 2007
Valopicitabine Development Program Placed on Clinical Hold in the United States
CAMBRIDGE, Mass., July 13 (HSMN NewsFeed) -- Idenix Pharmaceuticals, Inc. (Nasdaq: IDIX ) today announced that after discussions with the United States Food and Drug Administration (FDA) the development program of valopicitabine (NM283) for the treatment of hepatitis C has been placed on clinical hold in the United States based on the overall risk/benefit profile observed to date in clinical testing."We are disappointed with the FDA's perspective on the program and are working with Novartis to evaluate our options for valopicitabine," said Jean- Pierre Sommadossi, Ph.D., chairman and chief executive officer of Idenix. "We remain committed to building a leading antiviral franchise and will continue to focus on ensuring a successful launch of Tyzeka®/Sebivo® and on advancing our pipeline. We have a novel non-nucleoside reverse transcriptase inhibitor being evaluated in phase I clinical testing for the treatment of HIV. Additionally, we have a comprehensive HCV discovery effort, which includes a second-generation nucleoside polymerase inhibitor that is being evaluated in IND-enabling preclinical testing and novel HCV non-nucleoside polymerase inhibitor and HCV protease inhibitor programs."
As of June 30, 2007, Idenix had approximately $160 million of cash, cash equivalents and marketable securities.
"Over the next few weeks, we will be taking a critical look at our expenses with the goal of investing in programs that we believe will create shareholder value," said Ronald Renaud, chief financial officer of Idenix. "Our balance sheet is strong and we believe that we have enough cash to fund early clinical development of the pipeline."
