A dual acting drug for enhancing radiotherapeutic benefit

摘要： 这项名为“增强放射性益处的双重作用药物”的建议， 旨在提供新化合物EWA001可以保护 在体内模型中，正常肺组织受到辐射诱导的损伤， 保护肿瘤组织电离辐射对放射性肺损伤的防护 辐射，特别是辐射诱发的肺炎和纤维化，是一种未满足的需求， 考虑到超过三分之二的患者将接受放射治疗， 在他们的癌症治疗过程中，这种并发症限制了他们的治疗。 治疗，甚至导致死亡。目的1：研究EWA001对肿瘤细胞的作用 LLC和人肿瘤异种移植物在体外和体内结合辐射。在目标2中，我们 将研究EWA001在预防和减轻放射性肺损伤方面的有效性 小鼠损伤。目前，还没有药物可以最大限度地减少辐射毒性， 正常组织而不干扰其抗肿瘤作用，并且该数据旨在导致 成功的第二阶段应用，我们将进一步开发临床前数据， 治疗放射性肺毒性和肺炎有效药物。

ABSTRACT: This proposal entitled "A dual acting drug for enhancing radiotherapeutic benefit" is designed to provide proof of concept evidence that the novel compound EWA001 can protect normal lung tissue from radiation-induced damage within an in vivo model without appreciably protecting neoplastic tissue. The protection of radiation induced lung toxicity from ionizing radiation and in particular, radiation induced pneumonitis and fibrosis, is an unmet need that may benefit thousands of patients considering that more than two thirds will receive radiation therapy during the course of their treatment for cancer with such complications limiting treatment or even resulting in death. In aim 1, we will examine the effect of EWA001 in tumor LLC and human tumor xenografts in vitro and in vivo in conjunction with radiation. In aim 2, we will investigate EWA001's efficacy at protecting against and mitigating radiation induced lung injury in mice. Currently, there is no drug available that would minimize radiation toxicity to normal tissue without interfering with its anti-tumor effect and this data is designed to lead to a successful phase II application where we will further develop the pre-clinical data towards an effective drug to treat radiation induced lung toxicity and pneumonitis.
