The accepted standard treatment of relapsing multiple sclerosis consists of medications for disease symptoms, including treatment for acute exacerbations. However, currently there is no therapy that alters the progression of physical disability associated with this disease. The purpose of this study was to determine whether interferon beta-1a could slow the(More)
BACKGROUND In patients with chronic infection with hepatitis C virus (HCV) genotype 1, treatment with peginterferon alfa and ribavirin for 48 weeks results in rates of sustained virologic response of 40 to 50%. Telaprevir is a specific inhibitor of the HCV serine protease and could be of value in HCV treatment. METHODS A total of 334 patients who had(More)
BACKGROUND Current therapy for chronic hepatitis C virus (HCV) infection is effective in less than 50% of patients infected with HCV genotype 1. Telaprevir, a protease inhibitor specific to the HCV nonstructural 3/4A serine protease, rapidly reduced HCV RNA levels in early studies. METHODS We randomly assigned patients infected with HCV genotype 1 to one(More)
BACKGROUND & AIMS VX-950 specifically inhibits the NS3.4A protease of hepatitis C and has antiviral activity in vitro. This phase I, placebo-controlled, double-blind study evaluated the antiviral activity, pharmacokinetics, and safety of VX-950 in patients with chronic hepatitis C (CHC). METHODS Thirty-four patients with genotype 1 CHC were randomized to(More)
The Multiple Sclerosis Collaborative Research Group trial was a double-blind, randomized, multicenter, phase III, placebo-controlled study of interferon beta-1a (IFNbeta-1a; AVONEX) in relapsing forms of multiple sclerosis. Initial magnetic resonance imaging results have been published; this report provides additional results. Treatment with IFNbeta-1a, 30(More)
BACKGROUND/AIMS While combination of peginterferon-alpha (PEG-IFN) and ribavirin (RBV) therapy is the current standard of care for chronic hepatitis C (CHC), only 44-51% of genotype-1 patients achieve a sustained virological response (SVR), and both agents produce treatment-limiting toxicities. In the hepatitis C virus (HCV) replicon system, merimepodib(More)
Fasting and postprandial stomach acid production were low in 16 of 37 Bangalees convalescing from cholera or non-vibrio cholera. Gastric juice of hypochlorhydric patients did not kill cholera vibrios in vitro, whereas that from normochlorhydric patients rapidly killed vibrios in concentrations up to 10(10)/ml. To determine whether hypoacidity resulted from(More)
UNLABELLED Merimepodib (MMPD) is an orally administered, inosine monophosphate dehydrogenase inhibitor that has shown antiviral activity in nonresponders with chronic hepatitis C (CHC) when combined with pegylated interferon alfa 2a (Peg-IFN-alfa-2a) and ribavirin (RBV). We conducted a randomized, double-blind, multicenter, phase 2b study to evaluate the(More)
BACKGROUND AND OBJECTIVE A phase III double-blind, placebo-controlled clinical trial demonstrated that interferon beta-1a (IFN beta-1a) (Avonex, Biogen) significantly delayed progression of disability in relapsing MS patients. The primary clinical outcome was time from study entry until disability progression, defined as > or = 1.0 point worsening from(More)
