This new class and generation of IVD includes pharmacogenetic tests and genetic tests for heritable markers, in vitro diagnostic multivariate index assays, expression profiling test system for cancer diagnosis, and drug metabolizing enzyme genotyping system, and many others. On the other hand, IVD is the most promising area for biotechnology and biopharmaceutical industry in Taiwan due to its relatively inexpensive cost and short duration for clinical development. Despite of its emerging importance for biotechnology industry in Taiwan and as well as in the world, few attention has been paid to statistical evaluation of the performance and characteristics of IVD. In this three-year project, we will develop statistical methods on the design and analysis in the following three areas: (a) evaluation of precision, and (b) evaluation of bioequivalence of nasal aerosols and nasal sprays, (c) evaluation of linearity and linear range. For evaluation of precision, under the design recommended by the approved guideline EP5-A2 of Clinical Laboratory Standard Institute (CLSI), we will develop testing procedures for determining whether the within-device variation and between-laboratory device are within the pre-specified limit. For evaluation of bioequivalence of nasal aerosols and nasal spray, due to nuisance parameters involving with mean and variances, we will apply the modified large sample (MLS) method and the method of the generalized pivotal quantities (GPQ) to derive the upper confidence limit of the linearized criteria proposed by the guidance of the US Food and Drug Administration. For evaluation of linearity and linear range of IVD, we will develop statistical methods for determination of the number of concentrations and intervals and spacing between concentrations under the design suggested in the approved CLSI guideline EP6-A of with respect to different criteria for evaluation of linearity such as average deviation from linearity (ADL), sum of squares of deviations from linearity, and coefficient of variation of deviations from linearity (CVDL). In addition, sample size estimation will be explored. Simulation studies will be conducted to evaluate the size and power of the proposed methods. In addition, the proposed methods will be illustrated with the real data.體外診斷醫療器材精密度體外生物相等性線性In vitro diagnostic devicelinearityprecisionbioequivalence體外診斷醫療器材品質評估之統計理論與方法學之研究
