[Translation] An open-label, dose-escalation, and dose-expansion Phase I/II clinical study to evaluate the safety, tolerability, pharmacokinetic characteristics, and preliminary efficacy of LM-108 for injection alone or in combination with toripalimab in patients with advanced solid tumors
I 期剂量递增阶段主要目的:评估 LM-108 单药或联合特瑞普利单抗在晚期实体瘤患者中的安全性和耐受性、确定最大耐受剂量( MTD)和/或 II 期推荐剂量( RP2D)。次要目的:评价 LM-108 单药或联合特瑞普利单抗的药代动力学(PK)特征;评价LM-108的免疫原性;评价LM-108单药或联合特瑞普利单抗的 初步抗肿瘤活性;评价生物标志物表达水平与LM-108单药或联合特瑞普利单抗抗肿瘤活性的相关性。Ⅱ期剂量扩展阶段主要目的:评估LM-108单药或联合特瑞普利单抗在晚期实体瘤患者中的客观缓解ORR)。次要目的:评估 LM-108 单药或联合特瑞普利单抗在晚期实体瘤患者中的缓解持续时间(DOR),疾病控制率(DCR),无进展生存期(PFS)以及总生存期 OS;评估 LM-108 单药或联合特瑞普利单抗在晚期实体瘤患者中的安全性和耐受性;评估 LM-108 单药或联合特瑞普利单抗在晚期实体瘤患者中的药代动力学特征;评价 LM-108 的免疫原性;评价生物标志物表达水平与 LM-108 单药或联合特瑞普利单抗抗肿瘤活性的相关性。
[Translation] The main purpose of the Phase I dose escalation phase is to evaluate the safety and tolerability of LM-108 alone or in combination with toripalimab in patients with advanced solid tumors, and to determine the maximum tolerated dose (MTD) and/or Phase II recommended dose (RP2D). Secondary objectives are to evaluate the pharmacokinetic (PK) characteristics of LM-108 alone or in combination with toripalimab; to evaluate the immunogenicity of LM-108; to evaluate the preliminary anti-tumor activity of LM-108 alone or in combination with toripalimab; and to evaluate the correlation between biomarker expression levels and the anti-tumor activity of LM-108 alone or in combination with toripalimab. The main purpose of the Phase II dose expansion phase is to evaluate the objective response (ORR) of LM-108 alone or in combination with toripalimab in patients with advanced solid tumors. Secondary objectives: To evaluate the duration of response (DOR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) of LM-108 alone or in combination with toripalimab in patients with advanced solid tumors; to evaluate the safety and tolerability of LM-108 alone or in combination with toripalimab in patients with advanced solid tumors; to evaluate the pharmacokinetic characteristics of LM-108 alone or in combination with toripalimab in patients with advanced solid tumors; to evaluate the immunogenicity of LM-108; and to evaluate the correlation between biomarker expression levels and the anti-tumor activity of LM-108 alone or in combination with toripalimab.
