BACKGROUND & AIMS SCH 503034 is a novel and potent oral hepatitis C virus (HCV) protease inhibitor. In this phase Ib study, we assessed safety parameters and virologic response of combination of SCH 503034 plus pegylated (PEG) interferon (IFN) alpha-2b in patients with HCV genotype 1 infections who were previously nonresponders to PEG-IFN-alpha-2b +/-(More)
Assessment of QT interval prolongation is often used for assessing the cardiac safety of a new drug. However, the correction of the QT interval for varying heart rates has potential bias due to various different correction factors. This article proposes a maximum likelihood (ML) approach for calculating the appropriate individual correction factor using the(More)
An algorithm was developed and tested for differentiating between the spatial distribution of large arrays of surface electromyographic (LASE) data from subjects with and without low back pain (LBP). The surface EMG data from 62 channels were collected from the low back of 161 healthy and 44 acute (less than 6-weeks) LBP subjects in three minimum stress(More)
The inability to measure borders and variation in the number of 1-mm cross sections acquired from an identical length of vessel in serial intravascular ultrasound (IVUS) pullbacks represents potential errors in calculating volumes by IVUS. In a clinical IVUS trial, the percentage of nonmeasurable lumen and external elastic membrane borders, and the percent(More)
