OM-85 in recurrent respiratory infections in children with wheezing lower respiratory tract diseases
Résumé de l'étude
The medication being studied in this trial is called OM-85 (hereafter referred to as the "investigational product"). OM-85 is a medication that enhances the body's immune defense. This study aims to investigate whether the investigational product is safe and effective in preventing respiratory infections (nose, throat, and lung). The efficacy of the investigational product in recurrent respiratory infections has already been demonstrated, but the efficacy of short-term treatment needs to be confirmed and the effects of long-term treatment evaluated, in children aged between 6 months and 5 years with wheezing lower respiratory tract diseases. In order to assess efficacy, the investigational product must be compared with a placebo. This is a capsule that looks like the investigational product but contains no active ingredient. Neither the parents nor the children nor the investigator/sponsor will know which study medication (either the investigational product or the placebo) the children are taking. The children will be randomly assigned (like drawing lots) to 1 of 3 treatment groups. These treatment groups are referred to as the BV-12 arm, BV-3 arm, and placebo arm: • BV-12 arm: Children in this treatment group receive the investigational product for 10 consecutive days per month for 12 consecutive months. • BV-3 arm: Children in this treatment group receive the investigational product for 10 consecutive days per month for 3 consecutive months. They then receive the corresponding placebo for 10 consecutive days per month for 9 consecutive months. • Placebo arm: Children in this treatment group receive the placebo for 10 consecutive days per month for 12 consecutive months.

Intervention étudiée
During the screening visit, it will be determined whether the children are eligible to participate in the study before treatment with the study medication begins. This screening visit will take place at the trial center during the first visit (Visit 1), within 20 days prior to or on the same day as the collection of baseline values/random assignment to the treatment group, which occurs at Visit 2. The treatment phase (months 1 to 12) includes the following visits: o The visit for the collection of baseline values/assignment to the treatment group (Day 1/Visit 2) takes place at the trial center. It may coincide with the screening visit but may also take place on another day. o Three visits at the trial center (months 3, 6, and 12/Visits 3, 4, and 5) o Monthly virtual visits in the form of phone calls (months 1, 2, 4, 5, 7, 8, 9, 10, and 11) The observation phase (months 12 to 18; the first day of the observation phase begins after Visit 5 is completed) includes the following visits: o Two virtual visits in the form of phone calls (months 14 and 16) o End-of-study visit at the trial center (month 18/Visit 6) During this study, the following examinations and measures will be performed: • Collection of the children's medical history and demographic data, as well as a questionnaire on previous medications prior to entry into the study • Monitoring of the children's vital signs (including blood pressure, heart rate, and body temperature [measured in the ear]), measuring the height and weight of the children, and performing a complete physical examination • Assessment of all adverse effects of the study medication during the study • Completion of a diary including questionnaires, either in paper form or as an electronic diary • At Visits 2, 5, and 6, nasal swabs (nasal secretions) will be taken from the children to establish baseline values (the initial amount before the study medication begins) of biomarkers (a test that provides information on how cells behave). • At Visit 2, mandatory blood samples will be taken from a vein in the children's arms; at Visits 5 and 6, blood samples may be taken (voluntarily/optionally). The following blood tests will be performed on the blood samples: o Genomics (a form of genetic testing of DNA). This is a voluntary measure that is only performed at Visit 2. o Determination of the number of certain blood cells, particularly the eosinophil count in the blood. Eosinophils are immune cells involved in the development of allergies and asthma. o Immunoglobulin E (IgE). IgE is a specific type of antibody that is produced in larger amounts by the immune system in allergic patients and can specifically recognize allergens (substances that trigger allergies). o Transcriptomics (study of RNA molecules in a cell), which allows for the recognition of the overall response of the body to the study medication and the identification of biomarkers of the response to the study medication. The total amount of blood taken at each of the above-mentioned visits is approximately 4.5 ml. The maximum amount of blood taken for the purposes of the study is approximately 13.5 ml.

Maladie en cours d'investigation
Recurrent respiratory infection with wheezing lower respiratory tract diseases
(BASEC)
Children of both sexes aged 6 months to 5 years inclusive. For children aged ≥ 1 year: ≥ 4 respiratory infections (according to the report of the parents or the legal representative of the participant [i.e., the guardian]), including ≥ 2 lower respiratory tract diseases with wheezing episodes (of which ≥ 1 episode required hospitalization or medical consultation) within 12 months prior to enrollment in the study. OR For children aged < 1 year: ≥ 2 respiratory infections (according to the report of the parents or the legal representative of the participant), including ≥ 1 lower respiratory tract disease with wheezing episode (of which ≥ 1 episode required hospitalization or medical consultation) within 6 months prior to enrollment in the study. The parents or legal representative of the study participant have given the required written consent after being informed. The written consent must have been obtained before study-related procedures, including preliminary measures, can be performed. (BASEC)
Critères d'exclusion
Anatomical abnormalities of the respiratory tract. Other chronic respiratory diseases (e.g., tuberculosis, cystic fibrosis). Any autoimmune disease. (BASEC)
