中文摘要
项目摘要/摘要:HPV是全球10%的女性癌症的必要原因,包括
99%的宫颈癌。 宫颈癌的发病率因地理区域和经济水平的不同而有显著差异。
发展中国家,其中85%以上发生在发展中国家。针对hrHPV的成功预防性接种
类型可以预防发育异常,从而宫颈癌。HPV疫苗接种和宫颈癌的全球估计数
按地区和收入水平进行的筛查显示,对许多较贫穷的妇女人口几乎没有提供任何服务。
国际吧有13种hrHPV类型加上一组11种可能致癌的类型。许可的HPV疫苗
所有针对HPV 16和HPV 18的疫苗,其中一种还针对宫颈癌中接下来的五种最常见的类型。以来
它们并不针对所有与癌症相关的HPV类型,即使在接种疫苗的妇女中也必须保持筛查,
增加了医疗费用。 此外,HPV疫苗严格的冷链要求提供了严重的
在发展中国家提供这些服务的障碍。我们的总体目标是开发一种负担得起的HPV疫苗
这两个扩展的保护范围,所有癌症相关的HPV类型,并在环境中是稳定的,
温度在这里,我们通过两项创新来实现这一目标:1)展示基于L2-Arg的保护性表位(RG 1),
其在HPV 16 L1 VLP表面上的独特位置上对于HPV是保守的,产生单一抗原,
广泛保护的HPV疫苗技术,RG 1-HPVVLP,和2)RG 1-HPVVLP疫苗在明矾上配制,
包埋在通过调节冻干和制剂参数形成的玻璃状有机基质中,
控制冰晶成核速率、玻璃化转变温度和其它材料性质,从而
防止在加工、运输和储存过程中降解。
假设1:冷链储存特性是目前HPV疫苗分销的重要障碍,
而研制一种含有热稳定佐剂的粉状RG 1-RG 1VLP疫苗将解决这一问题

英文摘要
Project Summary/Abstract: HPV is a necessary cause of 10% of all cancers of women globally, including
99% of cervical cancers. Rates of cervical cancer vary markedly by geographic region and level of economic
development, with >85% occurring in developing countries. Successful prophylactic vaccination against hrHPV
types can prevent dysplasia and thus cervical cancer. Global estimates of HPV vaccination delivery and cervical
screening by region and income level show virtually no significant delivery to many poorer populations of women
worldwide. There are 13 hrHPV types plus a group of 11 possibly carcinogenic types. Licensed HPV vaccines
all target HPV16 and HPV18, and one also targets the next five most common types in cervical cancer. Since
they do not target all cancer-associated HPV types, screening must be maintained even in vaccinated women,
adding to medical costs. In addition, the stringent cold-chain requirements of HPV vaccines provide a serious
impediment to their delivery in developing countries. Our overall goal is to develop an affordable HPV vaccine
that both extends the breadth of protection to all cancer-associated HPV types, and is stable at ambient
temperature. Here we address this goal with two innovations: 1) displaying an L2-based protective epitope (RG1)
that is conserved for HPVs in a unique position on the surface of HPV16 L1 VLPs, producing a single antigen,
broadly protective HPV vaccine technology, RG1-VLP, and 2) the RG1-VLP vaccine is formulated on alum and
embedded in glassy organic matrices formed by adjusting lyophilization and formulation parameters in order to
control ice crystal nucleation rates, glass transition temperatures, and other material properties and thereby
protect against degradation during processing, shipping and storage.
HYPOTHESIS 1: Cold chain storage properties are a significant barrier to the distribution of current HPV vaccines,
and the development of a powdered RG1-VLP vaccine including adjuvant that is thermostable will address this
need. Specific Aim 1: Develop a GLP freeze-dry protocol for a powder formulation of RG1-VLPs in alum and
study its in vitro temperature stability, and in murine models its immunogenicity and protective efficacy in
comparison to Gardasil9.
HYPOTHESIS 2: RG1-VLP vaccination is safe and well tolerated. Specific Aim 2: To perform a Dose Escalation
Phase I Trial of the Safety and Immunogenicity of thermostable RG1-VLP in 36 healthy female volunteers with
the inclusion of a control Gardasil9 arm in the study.
HYPOTHESIS 3: RG1-VLP vaccination of healthy women induces broadly protective serum antibody. Specific
Aim 3: To analyze the levels of protective antibodies in the serum of patients from the phase I study induced by
RG1-VLP vaccination or Gardasil9. We will utilize the passive transfer assay to measure protective responses,
as well as L2 and L1 VLP ELISA and in vitro neutralization assays to quantify antigen-specific neutralizing
antibody titers in serum.
