About this study
Official title: Not a Drug Trial. We Are Using Anti-IgE to Examine the Role of Pulmonary Mast Cells in Asthma
We are using anti-IgE to investigate the role of pulmonary mast cells in asthma.
Read the detailed description
Subjects with mild allergic asthma are examined before, immediately after and 2 months after a course of treatment with anti-IgE. The following are examined: Allergen skin tests, allergen induced asthma, peripheral blood basophils, pulmonary bronchial mucosal mast cells.
- Conditions
- Asthma
- Being tested

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
XolairDrug
Patients are administered Xolair
| Study group | Role | What they receive |
|---|---|---|
| xolair | Experimental | This is a single arm, parallel study examining differences of therapeutic outcomes of Xolair. Xolair is being examined as an intervention that might change the outcome of immunization. Receives: Drug: Xolair |
What is being measured
The primary outcome is the main question the study is designed to answer.
Anti-KLH Antibody. This is Measured by ELISA and Expressed as ELISA Units Which Are Derived by Dilution of Serum Samples Until the Result Falls on a Linear Portion of the Response Curve. Final Values Are Derived From ELISA Units and the Serum Dilution
Asthma and control patients are immunized with KLH. Mean levels of anti-KLH antibody as described above. This is measured by ELISA and expressed as ELISA units which are derived by dilution of serum samples until the result falls on a linear portion of the response curve. Final values are derived from ELISA units and the serum dilution
Measured: 6 months

Who may be eligible to take part?
The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 27 Sep 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Anti-KLH Antibody. This is Measured by ELISA and Expressed as ELISA Units Which Are Derived by Dilution of Serum Samples Until the Result Falls on a Linear Portion of the Response Curve. Final Values Are Derived From ELISA Units and the Serum Dilution (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Sep 2019; AzTrials last refreshed its copy on 27 Oct 2026.
