丙型肝炎病毒的即时核酸快速检测
CrossLife Technologies Inc.
项目总结/摘要
每年约有50万人死于丙型肝炎相关的肝病[1]。
丙型肝炎病毒可引起急性和慢性肝炎感染[1 - 2]。随着时间的推移,
慢性丙型肝炎可导致严重的健康问题,包括肝损伤,肝衰竭,
甚至肝癌。早期发现可以挽救生命。如果抗体测试是反应性的,
需要额外的基于核酸(RNA)的测试,以确定一个人目前是否
感染了丙型肝炎如果RNA测试是阳性的,这意味着一个人目前有
丙型肝炎,应该和医生谈谈,治疗这种疾病。
迫切需要敏感和特异性的床旁(POC)诊断,
丙肝病毒。基于核酸的POC检测有可能提供及时、敏感和
准确诊断HCV,以提供适当的护理和治疗-特别是在环境中
没有强大的临床实验室支持。POC检测法用于区分
哪些HCV血清阳性患者被感染,并确定患者是否有
开发持续的病毒学应答(SVR)将使治疗患者成为可能。
在当今高效泛基因型HCV治疗方案的全球基础上。
因此,我们的目标是开发一种快速,多重测试,检测和基因型所有
在需要时在<30分钟内检测六种HCV基因型,
非实验室环境和非技术人员。我们的专有测试利用了
新型探针反应化学,其允许DNA或RNA的多重检测,

英文摘要
Rapid, Point-of-Care Nucleic Acid Test for HCV
CrossLife Technologies Inc.
Project Summary/Abstract
Approximately 500 000 people die each year from hepatitis C-related liver diseases [1].
The hepatitis C virus can cause both acute and chronic hepatitis infection [1-2]. Over time,
chronic Hepatitis C can cause serious health problems including liver damage, liver failure,
and even liver cancer. Early detection can save lives. If the antibody test is reactive, an
additional nucleic acids based (RNA) test is needed to determine if a person is currently
infected with Hepatitis C. If the RNA test is positive, this means a person currently has
Hepatitis C and should talk to a doctor and treating the disease.
There is an urgent need for sensitive and specific point-of-care (POC) diagnostics for
HCV. Nucleic-acid based POC tests have the potential to offer timely, sensitive and
accurate diagnosis of HCV for imparting proper care and treatment – especially in settings
without robust clinical laboratory support. The availability of a POC assay to distinguish
which HCV seropositive patients are infected and ascertain whether patients have
developed a sustained virologic response (SVR) will make it possible to treat patients on
a global basis in the current era of highly effective pan-genotypic HCV regimens.
Therefore, we aim to develop a rapid, multiplex test that detects and genotypes all
six genotypes of HCV at the point-of-need in < 30 minutes and is appropriate for
non-laboratory settings and non-technical personnel. Our proprietary test exploits a
novel probe reaction chemistry that allows multiplexed detection of DNA or RNA without
sample purification, making it operable as a simple, hand-held test. Patient samples to be
input directly into the device without pre-processing and a disposable cartridge carry out
amplification of all targets and reports visible results that can be read by eye. We expect
a sensitivity (>90%) and specificity (>90%) to the qRT-PCR data on the same samples.
We will also conduct a large-scale validation and obtain World Health Organization (WHO)
expedited review approval and recommendation for procurement on our product and
market it first to non-governmental organizations (NGO) such as the Doctors Without
Borders or the Gates Foundation. We will obtain USFDA 510 K clearance in Phase 3 in
order to market our product in the U.S.
