Brief Summary
Human metapneumovirus (HMPV) is a virus that can cause respiratory illness. In older adults, those with asthma, infants, and children, illness can be severe, but in healthy adults the virus frequently causes no symptoms. The National Institute of Allergy and Infectious Diseases (NIAID) is working to develop a vaccine for HMPV that could be given to infants. Before potential vaccines can be tested, information about how HMPV affects healthy adults is needed. This study will examine the effects of exposure to HMPV in healthy adults.

Outcome Measures
Primary Outcomes (3)
Frequency of challenge virus (rHMPV-SHs) infection, defined as virus shedding in respiratory secretions or serological evidence of HMPV infection
Measured at baseline and on Days 1 to 9
rHMPV-SHs shedding, as measured by peak virus titer, mean sum of daily virus titers, and total duration of shedding
Measured at baseline and on Days 1 to 9
Frequency and severity of respiratory illness
Measured at study completion
Secondary Outcomes (6)
Magnitude, frequency, and duration of serum and nasal wash antibody responses induced by rHMPV-SHs
Measured at baseline and on Days 28, 120, and 180
Correlation between virus shedding and severity of clinical illness
Measured at study completion
Cytokine and chemokine concentrations in nasal wash samples and relationships between cytokine/chemokine induction, viral replication, and illness
Measured at study completion
T-cell mediated and innate immune responses
Measured at baseline and on Days 8, 28, and 180
Whether HMPV infection induces characteristic gene expression patterns in cells obtained from blood or nasal wash
Measured at baseline and Days 3, 5, 7, 8, 28, and 180
- +1 more secondary outcomes
Study Arms (1)
HMPV challenge virus
EXPERIMENTALParticipants will receive the HMPV challenge virus.
Interventions
Single dose of 10\^6 plaque forming units (PFU) of recombinant HMPV small hydrophobic genes (rHMPV-SHs)
Eligibility Criteria
You may qualify if:
- General good health, without significant medical illness, physical examination findings, or significant laboratory abnormalities as determined by the investigator
- Available for the duration of the trial
- Female subjects must agree to use effective birth control methods for the duration of the study
You may not qualify if:
- Pregnant
- Currently breastfeeding
- Evidence of clinically significant diseases in the nervous system, heart, lungs, liver, autoimmune system, or kidney or involving rheumatism, as determined by medical history, physical examination, or laboratory studies, including urine testing.
- Clinically significant alanine aminotransferase (ALT) levels, as determined by the principal investigator (PI)
- Behavioral or cognitive impairment or psychiatric disease that, in the opinion of the investigator, affects the ability to understand and cooperate with the study protocol
- Human metapneumovirus (HMPV) specific serum immunoglobulin A (IgA) titer greater than 1:50
- HMPV-specific nasal wash IgA titer greater than 1:50
- Positive urine drug toxicology test indicating narcotic use
- Medical, occupational, or family problems as a result of alcohol or illicit drug use during the past 12 months
- Other condition that, in the opinion of the investigator, would jeopardize the safety or rights of a subject participating in the trial or would render the subject unable to comply with the protocol
- History of hypersensitivity reactions
- Diagnosis of asthma or reactive airway disease within the past 2 years
- Positive result on test for HIV
- Positive result on test for hepatitis C virus (HCV)
- Positive result on test for hepatitis B virus surface antigen (HBsAg)
- +10 more criteria
