MRG004A的作用机制十分精准：首先通过抗体部分识别并结合癌细胞表面过度表达的TF抗原，随后抗原-抗体复合物 通过受体介导的内吞作用进入癌细胞内部，在溶酶体内经蛋白酶降解释放出细胞毒素MMAE，进而导致癌细胞死亡。 这种"生物导弹"式的靶向递送机制能够最大限度提高药物在肿瘤部位的浓度，同时减少对正常组织的毒性。 8月1日，国家药品监督管理局药品审评中心(CDE)最新公示，乐普生物-B(02157)自主研发的靶向组织因子(TF)的抗体 偶联药物(ADC)MRG004A正式启动针对胰腺癌的三期临床试验。这一重要进展标志着这款创新药物距离上市又迈出了 关键一步，也为胰腺癌这一"癌王"的治疗带来了新的希望。 | 登记号 CTR20253026 | | | --- | --- | | 相关建记号 CTR20221675 | | | 药物名称 MRG004A | | | 药物类型 生物制品 | | | 临床申请受理号 企业选择不公示 | | | 适应症 晚期胰腺癌 | | | 试验专业题目 | MRG004A联合最佳支持治疗对比安慰剂联合最佳支持治疗在晚期脚腺癌中的随机对照,双盲、多中心Ⅲ期临床研究 | | 试验通俗题 ...
