TNF抗体新药有望助力NASH细胞疗法

2018-04-12 药明康德 药明康德

开发肝细胞疗法的医药公司Promethera Biosciences日前宣布收购瑞士生物医药公司Baliopharm AG。此次收购补充了Promethera的药物管线,添加了特异性结合肿瘤坏死因子受体1(TNF-R1)的抗体候选药物。这种新型治疗策略与Promethera独特的肝细胞疗法相结合,可为患有非酒精性脂肪性肝炎(NASH)和患有其他潜在严重肝病的患者提供更好的治疗选择。

开发肝细胞疗法的医药公司Promethera Biosciences日前宣布收购瑞士生物医药公司Baliopharm AG。此次收购补充了Promethera的药物管线,添加了特异性结合肿瘤坏死因子受体1(TNF-R1)的抗体候选药物。这种新型治疗策略与Promethera独特的肝细胞疗法相结合,可为患有非酒精性脂肪性肝炎(NASH)和患有其他潜在严重肝病的患者提供更好的治疗选择。

Promethera是肝细胞药物领域的领导者,该公司领先的临床项目源自其专利细胞技术平台HepaStem,旨在从其免疫调节和抗纤维化特性中受益。除了基于细胞的药物管线,该公司还开发抗体技术,以补充和丰富治疗选择。

Baliopharm专注于开发治疗类风湿关节炎、克罗恩病、银屑病和多发性硬化症等自身免疫性疾病和癌症的新型抗体疗法。Baliopharm的抗体管线由两种选择性TNF-R1拮抗剂Atrosab和Atrosimab,以及抗CD20/CD95的双特异性抗体Novotarg组成。

由于TNF-α通路和TNF-R1与许多炎症性疾病,包括导致纤维化的慢性肝病有关,所以治疗性抗体不管是作为单独疗法,还是与Promethera的细胞疗法技术HepaStem联用都是一种有价值的策略。通过此次收购,Promethera获得了Baliopharm的全部抗体开发项目,特别是建立独特的下一代选择性TNF-R1抑制剂,包括新型抗体候选药物Atrosimab。

“收购Baliopharm为我们的细胞管线添加了非常有前途的抗体资产,通过我们专有的联合治疗选择,使NASH治疗策略多样化。随着细胞疗法HepaStem在这一适应症中向临床试验迅速发展,以Atrosimab为代表的互补性和潜在协同性方法加强了我们的产品组合,从知识产权和科学的角度来看具有极高的价值和独特性,”Promethera总裁兼首席执行官John Tchelingerian博士说:“凭借今天的收购,Promethera重申了自己的承诺,并进一步实现了自己的愿景。利用基于细胞和生物驱动的方法,成为严重肝病领域领先的药物开发机构。”

Baliopharm首席执行官Andreas Herrmann博士评论说:“今天的声明证明强大的科学是我们使用新型抗体Atrosimab进行下一代抗TNF-R1开发项目的基础。Promethera有能力推动Atrosimab的开发,探索独特的组合策略,在未来为NASH患者提供更好的治疗选择。”

我们期待此次收购能够为治疗包括非酒精性脂肪肝炎在内的多种严重肝病开发更多新疗法。
