项目摘要

DESCRIPTION (provided by applicant): HCV is responsible for 60% of the cases of chronic hepatitis and 50% of cases of cirrhosis, end- stage liver disease, and liver cancer. An effective vaccine has proved elusive and the preferred therapy with pegylated interferon is effective in less than 50% of patients with genotype 1 and 75% of patients with genotypes 2 or 3. Clearly, new treatment alternatives are needed. Interest in HCV IRES RNA as a drug target is reflected by the increasing number of small and large pharma companies pursuing that goal. MetalloPharm has created a novel platform technology (metallodrugs) that has the potential to irreversibly destroy the HCV IRES RNA. The specific aims are directed toward selection of a lead and back-up drug candidate for IND-enabling pre- clinical testing following validation of cellular mode of action against IRES RNA and uptake mechanisms; assessment of PK, toxicity and efficacy data; and exploration of methods to improve serum half life.

描述（由申请人提供）：HCV造成60％的慢性肝炎病例和50％的肝硬化病例，末期肝病和肝癌。事实证明，一种有效的疫苗难以捉摸，使用叶甲状干扰素的首选治疗在不到50％的基因型1和75％的基因型2或3患者中有效。显然，需要新的治疗替代方法。对HCV IRES RNA作为药物目标的兴趣反映了越来越多的小型制药公司追求该目标的大型制药公司。金属载体创造了一种新颖的平台技术（冶金），该技术有可能不可逆地破坏HCV IRES RNA。具体目的是针对选择铅和备用药物候选药物，用于在验证针对IRES RNA和摄取机制的细胞作用模式后，进行临床测试。评估PK，毒性和功效数据；以及探索改善血清半衰期的方法。
