~~Anidulafungin~~On ~~Phase~~February 324, ~~Clinical~~2005, ~~Trial~~the ~~Update~~Company announced that it has received the acceptance to file notification and been granted priority review status by the FDA for the Company’s New Drug Application (“NDA”) for dalbavancin, a novel antibiotic for the treatment of complicated skin and soft tissue infection.

• Operator: Introduces Mr. George Horner, Vicuron Pharmaceuticals Inc.’s Chief Executive Officer.

• George Horner: Thank you for joining us this morning. Also on today’s call with me is our Chief Financial Officer Dr. Dov Goldstein and Chief Medical Officer, Dr. David Krause.

• Before I begin my formal remarks, first let me start with our safe harbor statement. During the course of this conference call, we will state our beliefs and make projections and other forward-looking statements regarding future events of Vicuron. We wish to caution you that such statements are predictions and expectations and actual events or results may differ materially. We refer you to Vicuron’s publicly filed SEC disclosure documents for a detailed description of the risk factors affecting our business, especially the Forms 10-Q and 10-K. These documents identify important factors that could cause our actual results to differ materially from our predictions and other forward-looking statements.

• Today we are pleased to announce phase 3 results demonstrating superiority of anidulafungin over fluconazole in invasive candidiasis/candidemia, the most common hospital-acquired fungal infection.

• The study compared anidulafungin to fluconazole, a current standard of care, and was designed to show non-inferiority. Anidulafungin was superior to fluconazole in the primary endpoint which was global response at the end of intravenous therapy in the microbiological intent-to treat population.

• Anidulafungin also demonstrated non-inferiority or superiority in all secondary endpoints, including response at the two-week and six-week follow-up visits after completion of therapy.

• Anidulafungin was well tolerated in the study, with a comparable side effect profile to fluconazole.

• Invasive candidiasis and candidemia are infections caused by Candida, which can invade various organs or the bloodstream. Candida is the fourth most common cause of bloodstream infections, and the most common fungal cause. Invasive Candida infections are more common in people who are immunocompromised, such as those with cancer, organ transplants or burns. Such infections are associated with high mortality in these critically ill patients.

• Now I will turn to the clinical trial results.

• This was a double-blind, multi-center, randomized Phase 3 trial examining anidulafungin compared to fluconazole, a standard of care agent.

• We studied a 100 mg daily dose of anidulafungin preceded by an initial 200 mg loading dose of anidulafungin versus a 400 mg daily dose of fluconazole preceded by an initial 800 mg loading dose of fluconazole, in 256 patients with invasive candidiasis/candidemia.

• Patients received daily IV infusion of either anidulafungin or fluconazole for 10 to 42 days. The primary endpoint was global assessment of composite clinical and microbiological response at the end of IV therapy in the microbiology intent-to-treat population.

• Success in the global response at end of IV therapy in the microbiology intent to treat population was 75.6 percent (96/127) with anidulafungin and 60.2 percent (71/118) with fluconazole, a statistically superior difference in favor of anidulafungin. (95 percent confidence interval of the difference: 3.85, 26.99)

• The secondary endpoint of success in the global response at two-week follow up visit in the microbiology intent to treat population was observed in 64.6 percent (82/127) of patients in the anidulafungin arm and 49.2 percent (58/118) of patients in the fluconazole arm. This also demonstrated statistical superiority. (95 percent confidence interval of the difference: 3.14, 27.68)

• The secondary endpoint of success in the global response at six-week follow up visit in the microbiology intent to treat population was observed in 55.9 percent (71/127) of patients in the anidulafungin arm and 44.1 percent (52/118) of patients in the fluconazole arm demonstrating non-inferiority. (95 percent confidence interval of the difference: -0.6, 24.28)

• Anidulafungin demonstrated comparable tolerability to fluconazole in the study.

• We are very pleased with these trial results.

• With these data Vicuron is on track to file a New Drug Application for invasive candidiasis/candidemia in the third quarter of this year and to complete submission of an amendment to the esophageal candidiasis NDA in the second quarter.

• We will continue to work closely with the agency and update you all as necessary.

• We believe that these exciting new results demonstrating the superiority of anidulafungin should enable us to competitively position anidulafungin, if approved by the FDA, as an important new option to battle invasive fungal infections due to Candida.

• Thanks for your time this morning. I will now open up the call to questions.
