It is intended to replicate, as closely as is possible in healthcare insurance claims data, the trial listed below/above. Although many features of the trial cannot be directly replicated in healthcare claims, key design features, including outcomes, exposures, and inclusion/exclusion criteria, were selected to proxy those features from the trial. Randomization is also not replicable in healthcare claims data but was proxied through a statistical balancing of measured covariates according to standard practice. Investigators assume that the RCT provides the reference standard treatment effect estimate and that failure to replicate RCT findings is indicative of the inadequacy of the healthcare claims data for replication for a range of possible reasons and does not provide information on the validity of the original RCT finding."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'maximumAge': '120 Years', 'minimumAge': '12 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'This study will involve a new user, parallel group, propensity score-matched, retrospective cohort design comparing budesonide-formoterol versus budesonide alone.

The initial eligible cohort entry date was the first date after July 21, 2006 for both the databases investigated (IBM MarketScan, Optum CDM). The last date eligible as cohort entry date was the end of available data for IBM MarketScan and Optum CDM. The following eligible cohort entry dates were included:\n\n* IBM MarketScan: July 21, 2006 - December 31, 2018 (end of available data)\n* Optum CDM: July 21, 2006 - June 30, 2020 (end of available data)\n\nInclusion Criteria:\n\n* ≥12 years of age\n* Documented clinical diagnosis of asthma for ≥1 year prior to randomization\n* History of at least one asthma exacerbation in the previous year (but none in the 4 weeks prior to randomization. An asthma exacerbation was defined as an event requiring treatment with systemic corticosteroids or requiring hospitalization (i.e. an inpatient stay or \\>24-hour stay in the observation area of an emergency room or local equivalent)\n* Receiving either:\n\n 1. A stable dose of ICS alone or in combination with a LABA, leukotriene receptor antagonist or other maintenance therapy/therapies for ≥4 weeks prior to randomization (any patient maintained on a stable high-dose ICS with or without a LABA or LTRA or other maintenance therapy/therapies was required to have an ACQ6 total score of \\<1.5 at screening) OR\n 2. A stable dose of LTRA or xanthine monotherapy (for ≥4 weeks prior to randomization) or daily SABA (in the 4 weeks before randomization but ≤8 puffs a day on two consecutive days, or ≥25 puffs in one day, in the 7 days prior to screening). Patients on LTRAs, xanthines, or daily SABA, were eligible only if they recorded an ACQ6 total score of ≥1.5, and in the investigator's clinical judgment, the patient's asthma severity could have justified treatment with ICS or ICS/LABA combination\n\nExclusion Criteria:\n\n* A history of life-threatening asthma (defined as an asthma episode that required intubation and/or was associated with hypercapnia requiring non-invasive ventilatory support)\n* One of the following:\n\n 1. Any asthma exacerbation requiring systemic corticosteroids within 4 weeks prior to randomization OR\n 2. \\>4 separate exacerbations OR\n 3. \\>2 hospitalizations (an inpatient stay or \\>24- hour stay in the observation area of an emergency room or local equivalent) due to asthma in the previous year\n* Received systemic corticosteroids for any reason in the 4 weeks prior to randomization\n* Had an ongoing asthma exacerbation requiring systemic corticosteroids\n* Concurrent respiratory disease (chronic obstructive pulmonary disease, chronic bronchitis, emphysema, idiopathic pulmonary fibrosis, bronchiectasis, and/or any pulmonary disease)\n* A smoking history of \\>10 pack-years\n* Respiratory infection or other viral/bacterial illness\n* Pregnancy (current/planned) and lactation\n* Malignancy (with the exception of basal cell carcinoma) within the 5 years prior to study commencement\n* Omalizumab or any other monoclonal/polyclonal antibody use in the 6 months prior to randomization\n* Concomitant β-blocker use\n* Drug/alcohol abuse"}, 'identificationModule': {'nctId': 'NCT04892732', 'briefTitle': 'Replication of the D58 Asthma Trial in Healthcare Claims Data', 'organization': {'class': 'OTHER', 'fullName': "Brigham and Women's Hospital"}, 'officialTitle': 'Replication of the D58 Asthma Trial in Healthcare Claims Data', 'orgStudyIdInfo': {'id': '2018P002966-DUP-D58'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Budesonide', 'description': 'Reference Group', 'interventionNames': ['Drug: Budesonide']}, {'label': 'Budesonide-formoterol', 'description': 'Exposure Group', 'interventionNames': ['Drug: Budesonide-Formoterol']}], 'interventions': [{'name': 'Budesonide', 'type': 'DRUG', 'description': 'Budesonide dispensing claim is used as the reference group.', 'armGroupLabels': ['Budesonide']}, {'name': 'Budesonide-Formoterol', 'type': 'DRUG', 'description': 'Budesonide-Formoterol dispensing claim is used as the exposure group.', 'armGroupLabels': ['Budesonide-formoterol']}]}, 'contactsLocationsModule': {'locations': [{'zip': '02120', 'city': 'Boston', 'state': 'Massachusetts', 'country': 'United States', 'facility': "Brigham and Women's Hospital", 'geoPoint': {'lat': 42.35843, 'lon': -71.05977}}], 'overallOfficials': [{'name': 'Shirley Wang, PhD, ScM', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': "Brigham and Women's Hospital"}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': "Brigham and Women's Hospital", 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Assistant Professor', 'investigatorFullName': 'Shirley Vichy Wang', 'investigatorAffiliation': "Brigham and Women's Hospital"}}}}
