| その他関連情報/Other related information | 【中間解析】
本試験では、全体の半分の症例(125例目)が試験終了した時点で、試験薬の有効性が試験計画段階の予想よりも優れているかどうかを評価し、試験中止の判断を行うことを目的に中間解析を1度実施する。中間解析の結果、AST-120内服群と非内服群、Mg内服群と非内服群のいずれかで、Pocock型のα消費関数による優越性が認められた場合、独立データ解析委員の判断を仰ぎ、試験を早期中止する。 |
[Sample size analysis and Interim Analysis]
We estimated that a sample size of 222 patients (111 in each group) would provide a power of 90% at an overall two-sided alpha error level of 0.05 to detect a 30% relative reduction in the percent change in CAC scores in the magnesium oxide group compared to the control group, given that an annual percent change in CAC score among pre-dialysis diabetic CKD patients was 14% according to a previous study. Assuming a dropout rate of approximately 10%, we planned to enroll a total of 250 patients. An interim analysis for efficacy was to be performed after a half of the planned number of patients (i.e., 125 patients) reached the end of the study, with use of the Lan-DeMets alpha-spending-function approach (Pocock type). According to a result of the interim analysis, an independent data monitoring committee determines whether the study should be continued or prematurely terminated. |
