百奥赛图将在会议上公布多项自主研发全人单抗、双抗、双抗ADC新药的研究成果，以及创新动物模型在药物评价中的应用研究，并在会议现场设立展台#1043。
一、多项新药研究及技术平台成果
1.TNFR2非阻断型全人抗体药物（1C3）
标题：1C3, a Novel Non-blocking Anti-human TNFR2 Antibody Generated From RenMice, Exhibits Promising Anti-tumor Activity and Safety in Syngeneic Tumor Models in Humanized TNFR2 Mice
话题：Immunology
编号：2907
展示时间：Tuesday, April 12th 9:00 AM-12:30 PM Poster Session
简介：1C3是一款新型TNFR2非阻断治疗抗体，能够促进CD8+ T细胞增殖，增加肿瘤微环境中效应T细胞的比例。该药物由百奥赛图与宝船生物合作开发，经百奥赛图自主研发RenMice小鼠进行抗体发现，B-hTNFR2小鼠体内高通量筛选获得。临床前研究表明1C3单药及与PD-1或PD-L1抗体联用在小鼠肿瘤模型中均有良好的抗肿瘤活性。
2.Her2-Trop2全人双抗ADC（YH012）
标题：YH012, a Novel Bispecific Anti-HER2 and TROP2 Antibody-Drug Conjugate, Exhibits Potent Antitumor Efficacy
话题：Immunology
编号：4256
展示时间：Wednesday, April 13th 9:00 AM-12:30 PM Poster Session
简介：YH012是一款百奥赛图自主研发的HER2-TROP2全人双特异性抗体偶联药物（双抗ADC）。HER2与TROP2在胃癌、结直肠癌、膀胱癌和乳腺癌等多种肿瘤上共表达。临床前研究中，HER2-TROP2 BsAb与母本单抗相比增加了内吞活性，而单价HER2或TROP2单抗内吞活性降低，YH012较单抗HER2/TROP2-ADC具有更强的体外细胞杀伤活性。YH012在非小细胞肺癌和胃癌CDX小鼠模型体内均显示出良好的抗肿瘤活性。
3.PD-1-CD40 双特异性抗体（YH008）
标题：YH008, a PD-1-CD40 Bispecific Antibody, Inhibits Tumor Growth In Vivo Through PD-1-Dependent Activation of CD40 Signaling
话题： Immunology
编号： 5615
展示形式：E-Poster
简介：YH008是一款抗PD-1/CD40 Fc沉默的IgG1亚型双特异性抗体。临床前研究中，YH008在B-hPD-1/CD40小鼠B16F10肿瘤模型中显示出剂量依赖的抗肿瘤活性，该抗体以PD-1依赖的方式激活CD40，促进树突细胞增殖和活化，增加肿瘤浸润CD8+ T细胞/Treg细胞比率。在100 mg/kg的高剂量下，YH008未升高B-hPD1/hCD40小鼠血液中的肝酶。同样，在食蟹猴剂量递增研究中未观察到显著不良事件。YH008目前处于临床前开发阶段，预计于2022年递交IND申请。
4. 新型TCRm抗体药物开发平台
标题：Generation of TCR-like fully human antibodies against HLA-antigen-peptide complexes using HLA transgenic RenMice
话题：Therapeutic antibodies
编号：2885
简介：百奥赛图建立了基于HLA/RenMice小鼠的TCRm抗体开发平台，能够很好的针对胞内抗原靶点进行高通量的TCRm抗体开发，较天然TCR相比，TCRm抗体具有更高的亲和力和特异性。
5.规模化抗体新药开发-“千鼠万抗”计划（RenMice HiTS Platform）
标题：Identifying New Therapeutic Antibodies Using Knockout Mice Expressing Human Immunoglobulin Variable Domain Genes
话题：Experimental and Molecular Therapeutics
编号：1891
