靶向双肿瘤相关抗原（tumor-associated antigen，TAA）的双抗ADC（bispecific ADC）具有多种潜在抗肿瘤优势：

1. 同时靶向双肿瘤驱动分子，克服耐药性；

2. 识别双TAA共表达的肿瘤细胞，增加靶向肿瘤特异性，降低脱靶毒性；

3. 双靶点组合产生新的内吞动力学机制，更高效的杀伤肿瘤。

基于RenLite平台的双抗ADC构建

百奥赛图双抗ADC平台优势

1. RenLite来源的共同轻链抗体易于构建双抗分子，且性质稳定易于后期开发，显著降低了CMC工艺开发难度
2. 靶点敲除（KO）小鼠免疫获得的抗体表位丰富，多物种交叉且物种间亲和力接近
3. 候选靶点多，多物种检测药效和毒性，开发周期短成功率高
