研究概览
简要总结
The purpose of this study is to evaluate the safety and clinical characteristics of a quantity of human rhinovirus Type 16 (HRV-16) in healthy volunteers. This source of HRV-16 will be subsequently used in viral challenge studies with new compounds that are intended to treat respiratory diseases.
详细描述
This is an open-label study in which all participants know the investigational substance being tested. Participants will be inoculated in the nose with HRV-16 and evaluated for the occurrence of cold symptoms and other indicators. There will be 3 phases: a screening phase, an HRV-16 infection phase, and a follow-up phase. The dose of virus being tested in this study has been previously used in other challenge studies. The total length of participation in the study will be about 4 weeks. Participant safety will be monitored.

结局指标
主要结局
Clinical symptoms to HRV-16
时间窗: 6 days
Clinical symptoms to HRV-16 will be assessed using the Cold Symptom Assessment form, which is a 5-point scale of the severity of cold symptoms.
Serological Response
时间窗: Approximately 4 weeks
Blood samples will be evaluated for serum-neutralizing antibody titer levels to HRV-16.
次要结局
- The number of adverse events(Approximately 4 weeks)
