Respiratory Syncytial Virus Human Challenge in Healthy Adult Volunteers

United States32 participantsStarted 2015-07-21

Plain-language summary

Background: \- Respiratory syncytial virus (RSV) can cause respiratory infections. Some of these can be life-threatening, especially in young children, the elderly, and people with weak immune systems. Researchers want to study RSV infection in a hospital setting in healthy adults. They want to use what they learn to test new treatments or vaccines in the future. Objectives: \- To study how the body responds to RSV. Eligibility: \- Healthy volunteers ages 18-50 Design: * Participants will be screened under another protocol. * Participants will have: * Medical history * Physical exams * EKG. Heart rhythm is measured with small sticky patches on the chest, arms, and legs. * Chest x-ray * Pulmonary function tests. This measures how much air a person can move into and out of the lungs. * Blood and urine tests * Nasal washes and/or nasal swabs. For the wash, the nose will be rinsed with a sterile liquid. For the swab, the inside of the nostril will be rubbed with a cotton swab. * Participants will have two, possibly three, follow-up outpatient visits, approximately 1, 2 and 6 months after receiving the dose of RSV. * Participants will stay in the hospital under isolation for 7 or more days after getting the virus. * The average stay is 10 days. Participants cannot leave the isolation unit. They cannot have visitors. * The virus should cause a mild to medium cold. * Participants will fill out a symptom card every day in the hospital and for 1 month after. * Participants will have 2 follow-up visits, 28 and 56 days after leaving the hospital. * Female participants who are sexually active must remain abstinent or use an effective form of birth control for 1 month before and after getting the virus.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Collection and assessment of expected and unexpected AEs.

Timeframe: Safety will be assessed continuously during inpatient and outpatient phases of the study through Day 56
