[Translation] A multicenter, open-label, single-arm phase I dose-finding and dose-expansion clinical study: Evaluating the safety, tolerability, pharmacokinetic characteristics and preliminary efficacy of XS-03 tablets in patients with advanced solid tumors with RAS mutations
主要目的:剂量爬坡阶段:评价XS-03片在RAS突变晚期实体瘤患者中的安全性和耐受性。确定XS-03片的最大耐受剂量(MTD)和/或II期临床研究推荐剂量(RP2D)。剂量扩展阶段:评价XS-03片在RAS突变晚期实体瘤患者中的初步疗效。次要目的:剂量爬坡阶段:确定XS-03片单次、多次口服给药后的药代动力学特征(PK)。初步评估XS-03片在RAS突变晚期实体瘤患者中的疗效。剂量扩展阶段:评价XS-03片在RAS突变晚期实体瘤患者中的安全性;确定XS-03片单次、多次口服给药后的药代动力学特征。
[Translation] Primary objective: Dose escalation phase: Evaluate the safety and tolerability of XS-03 tablets in patients with RAS-mutated advanced solid tumors. Determine the maximum tolerated dose (MTD) and/or recommended dose (RP2D) of XS-03 tablets for Phase II clinical studies. Dose expansion phase: Evaluate the preliminary efficacy of XS-03 tablets in patients with RAS-mutated advanced solid tumors. Secondary objective: Dose escalation phase: Determine the pharmacokinetic characteristics (PK) of XS-03 tablets after single and multiple oral administration. Preliminary evaluation of the efficacy of XS-03 tablets in patients with RAS-mutated advanced solid tumors. Dose expansion phase: Evaluate the safety of XS-03 tablets in patients with RAS-mutated advanced solid tumors; Determine the pharmacokinetic characteristics of XS-03 tablets after single and multiple oral administration.
