Sisunatovir will be given as multiple doses during the treatment period. RSV is a highly contagious virus that can lead to serious lung infections in patients with reduced ability to fight infection. Most vulnerable populations include babies, the elderly and patients that have received a bone marrow transplant.\n\nThis study is seeking healthy participants who are:\n\n1. Aged 18 to 45 years old and will agree to the use of highly effective methods of contraception.\n2. with a body mass index (BMI) of 18.0 to 30.0 Kg/m2 This study will consist of 2 cohorts of 33 participants each. In both cohorts participants will be exposed to the challenge virus on study day 0. Cohort 1 will receive either 200 mg of sisunatovir or placebo (looks the same as sisunatovir but contains no active medicine) 2 times a day for 5 days. Cohort 2 will receive either 350 mg of sisunatovir or placebo 2 times a day for 5 days. Participants will start taking the study medicine upon confirmation of RSV infection (or evening of Day 5 if not positive to RSV). The study medicine will be administered 12 hours apart (or twice daily). Each participant will remain in the quarantine unit until discharge on Day 12.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '45 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age 18 to 45 years, inclusive\n* In good health with no history of major medical conditions\n* A total body weight ≥ 50 kg and a body mass index (BMI) of \\>/=18kg/m2 and \\</=30kg/m2\n\nExclusion Criteria:\n\n* Evidence of any clinically significant or currently active major medical condition\n* Positive for Human Immunodeficiency Virus, active Hepatitis A, B or C test\n* Significant nose or nasopharynx abnormalities\n* Abnormal lung function\n* History or currently active symptoms suggestive of upper or lower respiratory tract infection'}, 'identificationModule': {'nctId': 'NCT03258502', 'briefTitle': 'A Study to Learn About the Effects of Multiple Doses of Sisunatovir on People With Respiratory Syncytial Virus (RSV) Infection', 'organization': {'class': 'INDUSTRY', 'fullName': 'Pfizer'}, 'officialTitle': 'A Randomised, Phase 2a, Double-Blind, Placebo-Controlled Study To Evaluate The Safety, Pharmacokinetics And Antiviral Activity Of Multiple Doses Of RV521 Against Respiratory Syncytial Virus Infection In The Virus Challenge Model', 'orgStudyIdInfo': {'id': 'REVC002'}, 'secondaryIdInfos': [{'id': 'C5241002', 'type': 'OTHER', 'domain': 'Alias Study Number'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'RV521', 'description': 'RV521 drug substance in capsule for oral administration', 'interventionNames': ['Drug: RV521']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Placebo', 'description': 'Micro-crystalline cellulose in capsule for oral administration', 'interventionNames': ['Drug: Placebo']}], 'interventions': [{'name': 'RV521', 'type': 'DRUG', 'description': 'RV521 drug in capsules', 'armGroupLabels': ['RV521']}, {'name': 'Placebo', 'type': 'DRUG', 'description': 'Placebo in capsules', 'armGroupLabels': ['Placebo']}]}, 'contactsLocationsModule': {'locations': [{'city': 'London', 'country': 'United Kingdom', 'facility': 'hVIVO Services Ltd', 'geoPoint': {'lat': 51.50853, 'lon': -0.12574}}], 'overallOfficials': [{'name': 'Pfizer CT.gov Call Center', 'role': 'STUDY_DIRECTOR', 'affiliation': 'Pfizer'}]}, 'ipdSharingStatementModule': {'url': 'https://www.pfizer.com/science/clinical_trials/trial_data_and_results/data_requests', 'ipdSharing': 'YES', 'description': "Pfizer will provide access to individual de-identified participant data and related study documents (e.g. protocol, Statistical Analysis Plan (SAP), Clinical Study Report (CSR)) upon request from qualified researchers, and subject to certain criteria, conditions, and exceptions.
