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的制造是一项复杂，劳动和资本密集型努力。在当前销售的重组蛋白中，凝血因子VIII的效率最低，是迄今为止最昂贵的人 /单位质量，药房价格为每克10,000,000美元。当前应用的目的是开发一种产品技术和制造过程，该过程可以提高VIII生物制剂的生产量和药房价格。表达治疗学已经开发并获得了两种技术，即一种生物工程因子VIII转基因，表现出比标准人类因子VIII的表达大100倍，而高性能的婴儿仓鼠肾脏（BHK）细胞系，被指定为BHK-MS，可以无限期地培养和扩展，并在悬浮液中均可培养和扩展。在当前的应用中，我们建议完成临床前制造，产品表征以及药理学和毒性研究，以提交研究新药应用。
