RATIONALE Nucleotide analogs are highly polar and ionic, which impose great challenges on bioanalysis. Ion-pairing liquid chromatography/tandem mass spectrometry (LC/MS/MS) is the predominant reported approach for such compounds. Assay ruggedness of ion-pairing LC/MS/MS methods was often a challenge due to the potential contamination of the ion source of(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)
Dasatinib (Sprycel) is a potent antitumor agent prescribed for patients with chronic myeloid leukemia (CML). To enable reliable quantification of dasatinib and its pharmacologically active metabolites in human plasma during clinical testing, a sensitive and reliable liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and(More)
The objectives of this study were to evaluate the safety, tolerability and pharmacokinetics (PK) of BMS-986001 as a single oral dose in healthy male subjects. Sixty-four healthy male subjects were randomized to receive a single dose of BMS-986001 or placebo in this single-blind, placebo-controlled, sequential ascending-dose study. There were eight treatment(More)
