With globalization of the pharmaceutical industry, newly approved drugs nearly always become available worldwide, including the 3 major pharmaceutical regions: the United States, Europe, and Japan. One might think that these drugs would have the same recommended dosing throughout the world, but this appears not to be true in many instances. The objective of(More)
Heterogeneity in the underlying mechanisms of disease processes and inter-patient variability in drug responses are major challenges in drug development. To address these challenges, biomarker strategies based on a range of platforms, such as microarray gene-expression technologies, are increasingly being applied to elucidate these sources of variability(More)
One approach to delivering cost-effective healthcare requires the identification of patients as individuals or subpopulations that are more likely to respond to an appropriate dose and/or schedule of a therapeutic agent, or as subpopulations that are less likely to develop an adverse event (i.e., personalized or stratified medicine). Biomarkers that(More)
PURPOSE Risks and benefits of marketed drugs can be improved by changing their labels to optimize dosage regimens for indicated populations. Such postmarketing label changes may reflect the quality of pre-marketing development, regulatory review, and postmarketing surveillance. We documented dosage changes of FDA-approved new molecular entities (NMEs), and(More)
Interindividual variation in pharmacodynamic (PD) response to drugs is an ongoing area of research for drugs in clinical development, pre- and postapproval. To characterize how pharmacogenomic (PG ) variations can serves a predictor of differences in PD outcomes, the pharmaceutical industry has incorporated PG /PD analysis into clinical drug development.(More)
