A + B Escalation Design without Dose De-escalation
A + B升级设计无剂量降级
译者:生物统计家园网 机器人LoveR
描述----------Description----------
The general A+B designs without dose de-escalation. There are A patients at dose level i.
一般的A + B设计没有剂量降级。在剂量水平,我有一个病人。
(1) If less than C/A patients have dose limiting toxicity (DLTs), then the dose is escalated to the next dose level i+1.
(1)如果低于C / A患者有剂量限制性毒性(DLTS),然后剂量升级到下一个剂量水平,我+1。
(2)If more than D/A (D>=C) patients have DLTs, then the previous dose i-1 will be considered the maximum tolerable dose (MTD).
(2)如果有多个D / A(D> = C)患者有双腔,那么前面的剂量I-1将被视为最大耐受剂量(MTD)。
(3)If no less than C/A but no more than D/A patients have DLTs, B more patients are treated at this dose level i.
(3)如果不低于C / A,但不超过D / A患者有双腔,B患者治疗剂量水平,我在此。
(4)If no more than E (where E>=D) of the total A+B patients have DLT, then the dose is escalated.
(4)如果没有超过E(E> = D)的总的A + B患者有DLT,然后剂量升级。
(5)If more than E of the total of A+B patients have DLT, then the previous dose i-1 will be considered the MTD.
(5)如果有比E,A + B组患者的总有DLT,则先前的剂量I-1将被认为是MTD。
