AACR2022丨百奥赛图将公布多项新药研究进展及创新模型临床前研究数据
2022.03.30





2022年美国癌症研究协会(AACR)年会即将于4月8-13日在美国New Orleans召开。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
