项目摘要

DESCRIPTION (provided by applicant): Lung infections with Pseudomonas aeruginosa are a significant health problem for patients with bronchiectasis and cystic fibrosis. A vaccine against P. aeruginosa would be useful to prevent colonization and infection. Adenovirus vectors are efficient vaccine platforms for genetic vaccines and we have developed various Ad-based vaccines expressing the P. aeruginosa OprF protein. Our prior studies established that, the chimpanzee-based Ad vector (AdC7) expressing OprF and a peptide motif (RGD) that enhances infection of immune cells administered directly to the lung provides long term immunity and protection against P. aeruginosa. This project aims to evaluate AdC7RGD.OprF following administration to the lung in another rodent model and then develop a GLP-clinical AdC7RGD.OprF vector, including toxicology and efficacy evaluation in non-human primates. This would then lead to the clinical development of an AdC7-based vaccine for a clinical study.

描述（由申请人提供）：铜绿假单胞菌肺部感染是支气管扩张和囊性纤维化患者的一个重要健康问题。针对铜绿假单胞菌的疫苗将有助于防止定植和感染。腺病毒载体是基因疫苗的有效疫苗平台，我们已经开发了各种表达铜绿假单胞菌OprF蛋白的基于Ad的疫苗。我们先前的研究证实，表达OprF和肽基序（RGD）的基于黑猩猩的Ad载体（AdC 7）增强直接施用至肺的免疫细胞的感染，提供针对铜绿假单胞菌的长期免疫和保护。该项目旨在在另一种啮齿动物模型中评估AdC7RGD.OprF在肺部给药后的效果，然后开发GLP-临床AdC7RGD.OprF载体，包括在非人灵长类动物中的毒理学和疗效评估。然后，这将导致基于AdC 7的疫苗的临床开发用于临床研究。
