Official title
Phase 1 Study of Dermatophagoides Farinae Inhalation in Humans
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this research study is to learn more about the effect of inhaled dust mite allergen extract on airway responses in allergic individuals with mild asthma. Information learned from this study will be used to identify a safe dose range of D Farinae extract for use in inhalation challenge studies. This study will also help determine how inhalation of the allergen affects mucociliary clearance (MCC) which is a measure of how quickly mucus clears from the airway.
