描述（申请人摘要）：酶缺乏 β-葡萄糖醛酸酶导致一种进行性衰弱和致命的疾病， 粘多糖代谢称为MPS VII或Sly病。 第一个被酶法鉴定的MPS， humans人类and animal动物models模型.关于治疗这种疾病的大量资料 存在于小鼠模型中，没有将基准研究转化为人类患者 部分原因是MPS VII的明显罕见。的 这项研究的长期目标是开发一种酶 MPSVII患者的辅助治疗。这项工作将由 在第一阶段开发高产细胞系， 第二阶段完整的商业化过程。该战略将利用 为MPS I酶替代开发的现有设施和程序 计划迅速转移到生产符合GMP的酶。工作 这将为申请IND和酶的临床试验奠定基础 MPS VII患者的替代治疗。 拟定商业应用： 从这项工作中产生的酶和过程可用于生产酶和 治疗患有粘多糖病VII的患者，这是一种严重的，危及生命的遗传性疾病， disorder.

DESCRIPTION (applicant's abstract): The deficiency of the enzyme beta-glucuronidaseleads to a progressive debilitatingand fatal disorder of mucopolysaccharidemetabolism known as MPS VII orSly disease.This disorderwas the first MPS to beidentified enzymatically and has been studiedextensively in humansand animalmodels. Thoughextensive data on thetreatment of thedisease exists in the mousemodel, no translation of the benchresearch to human patients has ever occurred due inpart to the apparent rarity of MPS VII. The keylong-term objective of this research is thedevelopment of an enzyme replacementtherapy for MPSVII patients. Thework will be accomplished by developing a highly productive cell line in phase I followed by thedevelopment of a complete commercial process in phase II. The strategy will exploit existing facilities and procedures developed for MPS I enzyme replacement program to rapidly move to theproduction of enzyme in GMP compliance. The work would thus set thestage for filing of an IND and a clinical trial of enzyme replacement therapy in MPS VII patients. PROPOSED COMMERCIAL APPLICATION: The enzyme and process created from this work can be used to produce enzyme and treat patients suffering from Mucopolysaccharidosis VII, a serious, life-threatening genetic disorder.
