随机方法(请说明由何人用什么方法产生随机序列):

总共评估600mg,750mg和900mg 3个剂量组。该阶段采用“3+3剂量递增原则”进行剂量递增,在每个剂量组所有受试者均完成第一周期给药后的安全评估并确定安全后方可递增到下一个剂量组。剂量限制毒性(DLT)观察期为第一周期的首次给药至给药后第28天,计划在第二周期第一天访视时完成DLT观察期,并由研究者进行总体评估。剂量递增流程图见附件13 剂量递增流程图。每个剂量组将入选最少3例可评价受试者,最多6例可评价受试者,本阶段的受试者数目预计约为9-18例。剂量递增或下降及MTD的确定将根据以下原则进行: (1) 如果在每个剂量组的前3例可评价受试者中未观察到DLT,可进行剂量递增。 (2) 如果在每个剂量组的前3例可评价受试者中观察到1例DLT,则这个剂量组将增加到6例可评价受试者。如果在6例可评价受试者中仅观察到1例DLT,则可进行剂量递增。 (3) 如果在一个剂量组,2例或2例以上发生DLT,不论入组几例受试者,该剂量定义为不可耐受剂量,应停止该剂量组的入组,并停止后续剂量递增。
