August 1, 2023 updated by: Universitaire Ziekenhuizen KU Leuven

WP3-Influence of Cromones on EVH-test in Young (Elite) Athletes Who Tested Positive for EIB (=Exercise Induced Bronchoconstriction)

This is a randomized, double-blinded, placebo-controlled trial of nebulized Sodium Cromoglycate (SCG) (Lomudal®) versus NaCl0.9% in athletes (11-18 year) with exercise-induced bronchoconstriction (EIB).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Screening and diagnosing EIB (studied by investigators in WP1 (s59778) and WP2 (s61602) of granted FWO-TBM project (T001417N)) in young athletes would only be useful if a safe and effective treatment is available. Sodium Cromoglycate (SCG) has a very nice safety profile but is less effective when compared to inhaled corticosteroids in asthma patients. However, SCG has been shown to be especially effective in exercise-induced asthma and to reduce metabolite secretion in athletes due to hyperpnoea. Although commercial interest in the drug has fainted, from a clinical point of view, it remains the ideal candidate to be used in adolescents with features of EIB at risk to develop asthma in whom today no treatment would be initiated.

This clinical trial (s63147), which is WP3 of the FWO-TBM project, is a randomized double-blinded trial with subjects who tested positive for the diagnosis of EIB in either WP1 or WP2. Subjects who gave assent and whose parents gave consent will be randomized (1/1) in a double-blinded trial to receive either (arm 1) Sodium Cromoglycate (SCG) (Lomudal®) or (arm 2) placebo, both 4X1 ampulla (2 mL) in aerosol daily, during 6 months.

During the previous trials, several tests were already performed. If subjects want to participate in this trial and the previous tests were more than 1 month ago, some tests will be repeated as a baseline: questionnaires, spirometry (with reversibility test) and EVH-test. After 3 months, regular intake as well as potential side effects will be evaluated. After 6 months, in addition to questionnaires, clinical examination and spirometry with reversibility test, the EVH-test will be repeated. Subjects will also be offered the possibility to repeat (as they did for WP1 and WP2) a blood and sputum sampling at 6 months. Afterwards, subjects will have the option to continue open-label treatment for 6 months.

The investigators want to investigate the influence of SCG on EVH-test in young athletes who tested positive for EIB.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

11 years to 18 years (Child, Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in percentage maximal fall of FEV1 after EVH-test compared to baseline maximal fall
Time Frame: 6 months
Individual's paired change in percentage maximal fall of FEV1 in relation to EVH-test between baseline values and values after 6 month treatment with sodium cromoglycate or placebo.
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Difference in symptom perception on a scale 0 to 5, with 5 maximum score per symptom
Time Frame: 6 months
Symptom perception will be assessed by a questionnaire (scale: no, very mild, little, moderate, serious, very serious) . Comparison will be done per individual and between both arms.
6 months
Asthma development
Time Frame: 6 months
Asthma development will be assessed by the occurrence of a positive reversibility test during the trial and compared between both arms.
6 months
Biomarkers in blood/sputum (optional)
Time Frame: 6 months
Change in expression of inflammatory markers and markers of epithelial damage after 6 months of treatment in blood and sputum (e.g. CC16, uric acid, IL1-B, ...)
