高變異藥物生物等效性評價確切樣本量計算
[Abstract]:Objective to study the exact sample size calculation method for bioequivalence evaluation of highly variable drugs (BE). Methods based on the principle of two-sided test and statistical distribution theory for evaluating the bioequivalence of conventional 2 脳 2 cross-design, the method of accurate sample size estimation was expounded. To analyze the methodological implications of the Food and Drug Administration (FDA) and European Drug Administration (EMA) guidelines for the study of highly variable drugs (BE). A method for calculating the exact sample size under two repeated cross designs for bioequivalence evaluation of highly variable drugs was derived. By means of SAS programming, the exact sample size list of different parameter setting under two repeated cross design is calculated, and compared with the results of the formula approximation method published in the literature, the difference law is analyzed. The result is that the EMA guidelines are more stringent than the FDA guidelines in adjusting bioequivalence limits using reference agents' variations in vivo, so it requires a larger sample size under the same parameters. Compared with the results of the approximate method in literature, when the ratio of geometric mean (GMR) is 1, the sample size of the exact method is larger than that of the approximate method, but for the case of GMR not equal to 1, the exact method is generally less than or equal to the approximate method. In this paper, the SAS program code for exact sample size calculation under EMA guidelines is also given, which can easily realize the exact sample size calculation under different parameter settings. Conclusion the exact sample size calculation method of the FDA and EMA guidelines for the study of bioequivalence evaluation of high variant drug BE is based on rigorous statistical theory and provides a concise and practical SAS program code. It is hoped to provide methodological support for the determination of sample size for the study of high-variant drug BE.
