New treatment option for Asthma
Official title Pilot Study to Identify the Mediators and Inflammatory Cell Surface Receptors Involved in Allergic Airway Inflammation
ClinicalTrials.gov ID: NCT00595491
What this study is testing
What is Bronchoscopy, Segmental Allergen Challenge, and Broncheoalveolar Lavage?
Bronchoscopy, Segmental Allergen Challenge, and Broncheoalveolar Lavage is an investigational medicine, being studied as a potential treatment for asthma.
Also referred to as One of 3 Standardized allergen extracts will be used:, Standardized Cat Hair Extract.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- Asthma is a heterogeneous disorder in which multiple potential inflammatory pathways contribute to airway obstruction. The biological basis for airway inflammation is the subject of intensive investigation.
- Phase 1: an early, usually small safety study
