Trial summary

In the past, doctors separated people with asthma into two groups, those with "allergic asthma" (about 2/3rds of people) and those with "non-allergic asthma". These labels are not much used now as the treatments for all people with asthma don't depend on this classification. Read more about this study

About this study

Official title: Cross Sectional Study to Evaluate and Associate Clinical and Laboratory Features of People With Allergic and Non-allergic Asthma

In the past, doctors separated people with asthma into two groups, those with "allergic asthma" (about 2/3rds of people) and those with "non-allergic asthma". These labels are not much used now as the treatments for all people with asthma don't depend on this classification. However, new treatments for asthma may become available and the classification may again become important. It could be useful for clinicians to know how to identify which patients are likely to benefit from particular treatments.

Additionally, some new blood tests are becoming available and some of these might help to categorise the type of asthma people have. What the study hopes to do is to identify patient features which make a diagnosis of "allergic asthma" more likely and to see which new blood tests are most likely to be helpful in confirming this diagnosis.

Questions about this trial

What is this clinical trial studying?

An observational study of Asthma and Allergy, run by National Services for Health Improvement Ltd at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 6 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 5 Dec 2013. 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 Kingdom. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Serum periostin level (time frame: 1 day). 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 5 Dec 2013.
