Abstract

In new drug development studies or clinical trials, zero-dose control is needed in general to determine the lowest dose level for a new drug which can act with our bodies. When the lowest dose level compared with zero-dose control has significant difference in effect, it is referred as minimum effective dose(MED). We propose, in this paper, parametric sequential test using updated control to identify the minimum effective dose(MED) level. Monte Carlo Simulation is adapted to examine the power and experimental significance levels of the proposed method with other methods.

신약 개발 연구 또는 임상시험에서 개발된 약이 0용량 대조군과 비교해 유의한 효과 차이가 있어 신체에 반응할 수 있는 최소 복용량을 결정하는데, 이 최소 복용량을 최소 효과 용량(Minimum Effective Dose; MED)이라 한다. 이 논문에서는 최소 효과 용량을 확인하기 위하여 업데이티드 대조군을 이용한 모수적 축차 검정법을 제안하였다. 또한 모의 실험을 통하여 기존의 검정법과 제안한 검정법의 실험유의수준(experimental significance level)과 검정력(power)을 비교하였다.
