About this study

Official title: Depigmented and Polymerised Allergenic Extract of Dermatophagoides Pteronyssinus as Antiasthmatic Treatment for Children With Slight Allergic Asthma to Mites

The objective of this trial is to evaluate the clinical effectiveness of the administration of a depigmented and polymerized allergen extract Dermatophagoides pteronyssinus in children with allergic asthma due to this mite

Read the detailed description

Immunotherapy is a specific treatment for allergic diseases. Unlike conventional pharmacological treatment, immunotherapy is the only treatment that could modify the natural course of allergic disease. This is a prospective double-blind placebo controlled study with three arms of treatment: placebo and two active (one of the active arms will receive subcutaneous immunotherapy and the other one will receive sublingual immunotherapy).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Symptom and medication scores

    Measured: 1 year per patient

Secondary outcomes (6)
  1. Comparison between sublingual and subcutaneous administration route, quality of life, cost-effectiveness, dose response prick-test, inflammatory markers, exhaled nitric oxide, inflammatory markers in exhalate bronchial condensate, use of health resources

    Measured: 1 year per patient

  2. QoL

    The Paediatric Asthma Quality of Life Questionnaire (PAQLQ) was developed to measure the functional problems (physical, emotional and social) that are most troublesome to children with asthmaQuestionnaire" E. Juniper

    Measured: 1 year

  3. Cost-effectiveness

    Measured: 1 year

  4. Dose response prick-test

    Measured: 1 year

  5. Inflammatory markers

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing DEPIGOID Dermatophagoides pteronyssinus and Polymerized TOL of Dermatophagoides pteronyssinus in people with Allergic Asthma, run by Laboratorios Leti, S.L. at 1 site in Spain.

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 5 inclusion and 9 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: stopped early, as of the sponsor's last update on 8 Mar 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 Spain. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Lack of recruitment). Results are not available in the source record.

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?

Symptom and medication scores (time frame: 1 year per patient). 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 8 Mar 2019.
