Abstract

In this chapter, we introduce statistical applications used in the design and analysis of a high throughput in vitro screening assay, QTiSA-HT (an acronym for QT-inotropy-Screening Assay-High Throughput), a proprietary in vitro platform used to characterize concentration-dependent effects of drugs that affect cardiac repolarization and contractility. Specifically, we discuss the design and analysis of cumulative, ascending dose concentration response studies, calculation of appropriate sample sizes, and the use of statistical significance tests and equivalence margins to provide robust estimates of true drug effects based on both concurrent and historical vehicle-control data. The goal of this chapter is to showcase how we search for solutions to real scientific problems arising in early phases of drug safety screening using statistical methods and tools.
