The amyloid-β peptide (Aβ)-in particular, the 42-amino acid form, Aβ1-42-is thought to play a key role in the pathogenesis of Alzheimer's disease (AD). Thus, several therapeutic modalities aiming to inhibit Aβ synthesis or increase the clearance of Aβ have entered clinical trials, including γ-secretase inhibitors, anti-Aβ antibodies, and amyloid-β precursor(More)
STUDY OBJECTIVE To analyze the pharmacokinetics of posaconazole administered as prophylaxis for invasive fungal infection (IFI) in neutropenic patients receiving chemotherapy for acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS). DESIGN Pharmacokinetic subanalysis of a phase III, prospective, randomized, multicenter, evaluator-blinded(More)
3535 Background: SCH 727965 is a potent and selective inhibitor of the cyclin-dependent kinases CDK1,2,5 and 9 with IC50's of < 5nM. SCH 727965 induces apoptosis in a broad array of tumor cell lines, causes tumor growth inhibition or regression in various xenograft models, and has a greater therapeutic index than flavopiridol in an in vivo screening model.(More)
CXCR3 is a chemokine receptor, upregulated upon activation of T cells and expressed on nearly 100% of T cells in sites of inflammation. SCH 900875 is a selective CXCR3 receptor antagonist. Thrombocytopenia and severe hemolytic anemia with acanthocytosis occurred in rats at doses of 75, 100, and 150 mg/kg/day. Massively enlarged spleens corresponded(More)
Oral temozolomide is approved in many countries for malignant glioma and for melanoma in some countries outside the USA. This study evaluated the exposure equivalence and safety of temozolomide by intravenous infusion and oral administration. Subjects with primary central nervous system malignancies (excluding central nervous system lymphoma) received 200(More)
Recently, the US Food and Drug Administration (FDA) approved the first two drugs (pirfenidone and nintedanib) indicated for the treatment of idiopathic pulmonary fibrosis (IPF). The purpose of this analysis was to leverage publicly available data to quantify comparative efficacy of compounds that are approved or in development. An analysis-ready database(More)
As BMS-820836 causes dose-dependent heart rate increases, QTcI, QTcF, QTcB, and QT beat-to-beat methods were compared in this thorough QT study in healthy subjects. Two parallel groups of subjects (n = 60 per group) received 2 mg (maximum therapeutic) or 4 mg (supratherapeutic) of BMS-820836 once daily for 14 days with uptitration. Another 60 subjects(More)
BACKGROUND A fixed-dose combination of daclatasvir (DCV; hepatitis C virus NS5A inhibitor), asunaprevir (ASV; non-structural protein 3 inhibitor), and beclabuvir (BCV; non-structural protein 5B inhibitor) is approved in Japan for hepatitis C virus genotype 1. OBJECTIVE The objective of this study was to assess the combination's drug-drug interaction(More)
BACKGROUND AND OBJECTIVE Daclatasvir is a potent, pangenotypic once-daily hepatitis C virus (HCV) NS5A inhibitor that is approved for the treatment of chronic HCV infection. The objective of this analysis was to characterize the pharmacokinetics of daclatasvir in subjects with chronic HCV infection. METHODS A population pharmacokinetic (PPK) model was(More)
Para-aminohippuric acid (PAH), an indicator of renal plasma flow, is a commonly used marker of organic anion transport by the kidney. An analytical method for PAH using HPLC was developed. The method is simple, fast and requires a minimum amount of organic solvent. Sample preparation involved protein precipitation with zinc sulfate. Para-amino benzoic acid(More)
