Romark Laboratories Initiates Phase II Study of Nitazoxanide in Treatment-Naive Patients With Chronic Hepatitis C Genotype 1 Trial Marks Third Study in Company's STEALTH C Clinical Program to Evaluate

Nitazoxanide in the Treatment of Chronic Hepatitis C



    TAMPA, Fla., April 18 /PRNewswire/ -- Romark Laboratories, a privately
 held biopharmaceutical company, today announced that it has begun enrolling
 patients in a U.S. clinical trial to evaluate nitazoxanide for the
 treatment of chronic hepatitis C. Preliminary data from the study is
 expected in the second half of 2008.
 
     The study, STEALTH C-3 (Studies to Evaluate Alinia for Treatment of
 Hepatitis C), is a Phase II randomized, double-blind, placebo-controlled
 clinical trial designed to evaluate the safety and efficacy of nitazoxanide
 in combination with peginterferon alpha-2a (Pegasys(R), Roche) and
 ribavirin (Copegus(R), Roche) in treatment naive patients with chronic
 hepatitis C infected with genotype 1.
 
     The primary objective of STEALTH C-3 is to evaluate sustained virologic
 response (SVR) with a treatment regimen of 4 weeks of nitazoxanide lead-in
 therapy followed by 48 weeks of standard of care plus nitazoxanide versus 4
 weeks of placebo lead-in followed by 48 weeks of standard of care and
 placebo. The trial will enroll 60 patients at 15 centers in the U.S.
 
     "Earlier clinical studies in patients with chronic hepatitis C infected
 with genotype 4 have shown that nitazoxanide improves virologic response
 rates when used in combination with standard of care," said Dr. Emmet B.
 Keeffe, Chief Medical Officer of Romark. "This study and our ongoing
 STEALTH C-2 trial, are designed to evaluate the effect of treatment with
 nitazoxanide plus standard of care in patients with genotype 1. Future
 clinical trials will explore new combinations and treatment durations,
 including current and emerging HCV therapies."
 
     STEALTH C Clinical Development Program
 
     STEALTH C-3 is the latest in a series of clinical trials aimed at
 gaining a broad understanding of how nitazoxanide may benefit patients with
 chronic hepatitis C genotype 1 when used in combination with peginterferon
 and ribavirin. Other studies in the STEALTH C program include the
 following:
 
 
-- STEALTH C-2, a randomized, double-blind, placebo-controlled trial currently enrolling up to 60 patients in the U.S. with chronic hepatitis C genotype 1 who have previously failed to respond to the standard of care with peginterferon and ribavirin. This trial is designed to evaluate the effectiveness and safety of nitazoxanide administered 500 mg twice daily for 4 weeks followed by nitazoxanide plus standard of care for 48 weeks compared to placebo for 4 weeks followed by standard of care plus placebo for 48 weeks. -- STEALTH C-1, an international study in 120 treatment-naive and interferon-experienced patients with chronic hepatitis C genotype 4. Interim results from the randomized controlled Phase II clinical trial were presented at the 58th Annual Meeting of the American Association for the Study of Liver Diseases (AASLD) in Boston, MA and demonstrated that 79 percent of interferon-naive patients with chronic hepatitis C genotype 4 receiving nitazoxanide plus the standard of care had a sustained viral response (SVR) at 12 weeks following treatment, compared to 43 percent of patients receiving the standard of care without nitazoxanide. The patients treated with nitazoxanide also experienced no relapse and no more side effects than patients who received the standard of care. Final study results (SVR-24) will be presented at the European Association for the Study of the Liver (EASL) in April 2008.

About Hepatitis C Hepatitis C is a blood-borne infectious disease that is caused by the hepatitis C virus (HCV). It is the most common cause of chronic hepatitis in the U.S. and may eventually lead to cirrhosis, liver cancer and liver failure. The disease is transmitted by contact with HCV-infected blood. A large majority of those infected do not show symptoms, but fatigue, abdominal pain and nausea can be common. The current standard treatment of care, peginterferon and ribavirin, is effective in about half of all patients treated. According to the Centers for Disease Control, HCV affects an estimated 4.1 million Americans. About Romark Laboratories Romark Laboratories (www.romark.com), a privately held biopharmaceutical company, has discovered and developed a new class of small molecule antivirals known as thiazolides. The Company is developing nitazoxanide, the first of the thiazolide class, for the treatment of chronic hepatitis C, and is developing other new thiazolides for treating viral diseases including chronic hepatitis B. Alinia(R) (nitazoxanide) is approved by the U.S. Food and Drug Administration and marketed by Romark for the treatment of infections caused by Cryptosporidium or Giardia.
