项目摘要

DESCRIPTION (provided by applicant): The manufacturing of recombinant coagulation factor VIII is a complex, labor and capital intensive endeavor. Of the recombinant proteins currently marketed, coagulation factor VIII is manufactured with the lowest efficiency and is by far the most expensive on a per unit mass basis with a pharmacy price of $10,000,000 per gram. The goal of the current application is to develop a product technology and a manufacturing process that can improve the production volume and pharmacy price of factor VIII biologics. Expression Therapeutics has developed and patented two technologies, a bioengineered factor VIII transgene that demonstrates 100-fold greater expression than standard human factor VIII, and a high performance baby hamster kidney-derived (BHK) cell line, designated BHK-MS, that can be cultured and expanded indefinitely and at high density in serum-free medium under suspension bioreactor conditions. In the current application, we propose to complete pre-clinical manufacturing, product characterization and pharmacology and toxicity studies necessary to submit an Investigational New Drug application.

描述（由申请人提供）：重组凝血因子VIII的生产是一项复杂的劳动力和资本密集型奋进。在目前市售的重组蛋白中，凝血因子VIII的生产效率最低，并且在每单位质量的基础上是迄今为止最昂贵的，每克的制药价格为10，000，000美元。本申请的目标是开发能够提高因子VIII生物制剂的生产量和制药价格的产品技术和生产工艺。Expression Therapeutics已开发并获得两项技术的专利，一种是经生物工程改造的因子VIII转基因，其表达量是标准人因子VIII的100倍，另一种是高性能幼仓鼠肾衍生（BHK）细胞系，命名为BHK-MS，该细胞系可在悬浮生物反应器条件下在无血清培养基中以高密度无限培养和扩增。在当前申请中，我们建议完成提交研究性新药申请所需的临床前生产、产品表征以及药理学和毒性研究。
