Roughly half of asthma sufferers experience such an exacerbation each year. Most of these events are triggered by viral infections, usually the common cold virus (rhinovirus).\n\nA key part of the body's defence against viral infections is to produce antiviral proteins called 'interferons', which have a myriad of effects to stop viruses. Previous work on cells taken from volunteers with asthma and healthy controls and infected with rhinovirus in the lab suggests interferon production is impaired in asthma. However when human volunteers with asthma are infected with rhinovirus, high levels of interferon are found a few days later - along with high numbers of virus. Whether the high virus numbers are the result of an initially weak interferon response, with subsequently unchecked viral replication leading to exaggerated interferon levels, is unknown as no one has measured interferons early in infection.\n\nBy infecting volunteers with asthma and healthy controls with rhinovirus at a known time, only done in a handful of centres worldwide, we will be able to measure interferons within hours of infection and well before symptoms develop."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '55 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Potential participants will be identified from hospital outpatient clinics, primary care, spirometry sessions/clinics, other research projects, and advertisements.', 'healthyVolunteers': True, 'eligibilityCriteria': "For Asthma group:\n\nInclusion Criteria:\n\n* Age 18-55 years\n* Doctor diagnosis of asthma\n* Previous asthma exacerbation\n\nExclusion Criteria:\n\n* Smoking history over past 12 months\n* Sinonasal disease, including current symptoms of allergic rhinitis\n* Asthma exacerbation or an upper respiratory viral infection within the previous six weeks\n* Current or concomitant use of oral steroids, monoclonal antibodies or nasal sprays\n* Neutralising antibodies to rhinovirus (RV)-16\n* Clinically significant diseases other than asthma which, in the opinion of the investigator, may either put the patient at risk because of participation in the study, influence the results of the study, an/or the patient's ability to take part in it\n* Inability to understand written or verbal information in English\n\nFor healthy control group:\n\nInclusion Criteria:\n\n• Age 18-55 years\n\nExclusion Criteria:\n\nAs for Asthma group and in addition:\n\n• History of asthma"}, 'identificationModule': {'nctId': 'NCT05050903', 'briefTitle': 'Early Antiviral Responses to Rhinovirus Infection in Asthma', 'organization': {'class': 'OTHER', 'fullName': 'Imperial College London'}, 'officialTitle': 'Early Antiviral Responses to Rhinovirus Infection in Asthma', 'orgStudyIdInfo': {'id': '21SM6879'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Asthma', 'interventionNames': ['Other: Rhinovirus infection']}, {'label': 'Healthy controls', 'interventionNames': ['Other: Rhinovirus infection']}], 'interventions': [{'name': 'Rhinovirus infection', 'type': 'OTHER', 'description': 'Inoculation with rhinovirus-16', 'armGroupLabels': ['Asthma', 'Healthy controls']}]}, 'contactsLocationsModule': {'locations': [{'zip': 'W2 1NY', 'city': 'London', 'state': 'Greater London', 'status': 'RECRUITING', 'country': 'United Kingdom', 'contacts': [{'name': 'Research Fellow', 'role': 'CONTACT', 'email': 'imperial.magic@nhs.net', 'phone': '020 7594 3751'}], 'facility': "Imperial College Respiratory Research Unit, St Mary's Hospital", 'geoPoint': {'lat': 51.50853, 'lon': -0.12574}}], 'centralContacts': [{'name': 'Research Fellow', 'role': 'CONTACT', 'email': 'imperial.magic@nhs.net', 'phone': '020 7594 3751'}], 'overallOfficials': [{'name': 'Sebastian Johnston', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Imperial College London'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Imperial College London', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
