Imaging Study of the Lungs During an Allergic Asthma Attack
NCT01547286 · View on ClinicalTrials.gov ↗
Study Summary
Asthma is a disease of rapidly increasing incidence that already affects more than 17 million people in the United States alone. It has long been known that areas of severely reduced airflow occur in asthma and contribute significantly to the impairment of gas exchange in this disease. However, the extent to which local blood flow changes during an asthmatic attack is unclear. The purpose of this study is using Positron Emission Tomography - Computed Tomography imaging to evaluate how the blood flow changes in the lungs during an asthma attack induced by allergens.
Interventions
- BIOLOGICAL Standardized Cat Allergen Extract and Standardized Dust Mite Allergen
- RADIATION Computed Tomography imaging, functional Positron Emission Tomography imaging
- DRUG Nebulized methacholine inhalation

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01547286
The ClinicalTrials.gov registry entry for NCT01547286 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 7 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Massachusetts General Hospital, which has 1,948 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Asthma appearing as the primary indexed condition, and to 3 interventions — of which Standardized Cat Allergen Extract and Standardized Dust Mite Allergen is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01547286 reports 1 study location spanning 1 distinct geographic area — top geographies include Massachusetts. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
