Allergic rhinoconjunctivitis due to birch pollen is a seasonal problem which manifests as a combination of nasal symptoms (such as congestion, runny nose, sneezing, itching of the nose) and ocular symptoms (such as red, itchy and watery eyes). For several birch-allergic patients, allergic rhinoconjunctivitis occurs with an oral allergy syndrome. The purpose of this study is to demonstrate the safety and efficacy of the study drug (STALORAL Birch 300 IR) in children and adolescents with birch pollen-induced allergic rhinoconjunctivitis, with or without asthma, when treated before and during the pollen season. Approximately 699 children will participate in this study. The study will be conducted worldwide in approximately 100 medical sites in about 14 countries. The total duration of the study will be approximately 20 months.

Eligibility | Inclusion Criteria: 1. Able to sign and date the informed consent/assent form prior to any trial-specific procedure. Patients may check a box on the assent form if they are unable to provide a signature. (Parents and/or authorised legal representative(s) will have to give written informed consent for minors in their custody) 2. Covered by a health insurance system as per local regulation. Demographics and Medical History 3. Aged =5 to =17 years old at the randomisation visit. 4. Documented, physician diagnosed, clinically relevant history of moderate to severe ARC induced by birch pollen (with or without asthma) despite having received treatment with symptom-relieving medication during at least 1 previous birch pollen season for ages 4 through 6 or at least 2 previous birch pollen seasons for ages 7 through 17 years at screening. 5. A Retrospective ARC Total Symptom Score (TSS) based on the previous birch pollen season = 12 out of a maximum possible score of 18 AND a retrospective score of at least 30 on a general Visual Analog Scale (VAS) (0-100) on the severity of symptoms as evaluated by the patient or by the parent/authorised legal representative if the patient is not able to perform the assessment, at screening (i.e., more than 4 months before the pollen season). Screening Tests and Evaluations 6. Positive Skin Prick Test (SPT) to Betula pendula at screening visit (the SPT is considered positive if it results in a wheal diameter = 3.0 mm [with positive control (histamine) = 3.0 mm and negative control = 0 mm]). The Sponsor will accept to include patients who have a documented positive SPT in their medical records if this SPT was performed during the previous 6 months preceding the screening visit at the same investigational site in which they are enrolled. 7. Positive specific Immunoglobulin E (IgE) to pollen allergens of Betula pendula at screening (CAP-RAST birch pollen allergens specific IgE = 0.7 kU/L). 8. Patients with non-clinically relevant co-sensitization to other inhalant allergens such as e.g., grass/rye, mites or animal dander can be enrolled, but only if: -the CAP-class with the referring allergen has to be at least 2 CAP-classes below the CAP-class for birch, and/or - the SPT-wheal has to be 2 mm smaller than the SPT-wheal for birch, and - clinical symptoms* and exposure to these allergens during the 2 IMP treatment periods are not anticipated (based on the clinical judgement and medical records) e.g., by not having regular contact the respective animal such as cat at home. *Relevant clinical symptoms of respiratory allergy are 4 nasal symptoms (runny nose, blocked nose, sneezing, itchy nose), associated or not to 2 eye related items (itchy eyes, watery eyes), associated or not to asthma (mainly cough, wheezing, shortness of breath). 9. Negative urine pregnancy test on all female patients of childbearing potential or who have had their first menarche prior to randomisation. Lifestyle Considerations 10. Internet access at home or via a portable device so that patients or the parent/authorised legal representative can complete the e-Diary in a dedicated application on a mobile phone daily via internet. Patients will start scoring at randomisation, i.e., 4 months before the pollen season. Exclusion Criteria: Medical History 1. Any clinical deterioration of asthma (i.e., asthma exacerbation) that resulted in emergency procedure/treatment or treatment with systemic corticosteroids within 3 months prior to randomisation. 2. For patients =7 years old: Reduced lung function at randomisation defined as Forced Expiratory Volume in 1 second (FEV1) < 70% of the predicted value. For patients with asthma, this is assessed on the patient's usual asthma medication following at least a 6-hour wash-out of Short-Acting Beta Agonists (SABAs), a 12 hour wash-out of Long-Acting Beta Agonists (LABAs) and a 24 hour wash-out for ultra-LABAs. Note: This criterion does not need to be fulfilled if the patient is <7 years old, as s/he cannot perform reproducible FEV1 manoeuvres despite coaching and is not considered as having a diagnosis of asthma. 3. Uncontrolled asthma with asthmatic therapies consistent with steps 4 or 5 as defined by Global Initiative for Asthma (GINA) 2022 received within 12 months prior to entry in the trial. Asthmatic patients with asthmatic therapies consistent with steps 1, 2 or 3 must be controlled (i.e. patients with controlled, mild and moderate asthma are eligible). 4. Oral inflammations such as oral lichen planus, oral ulcerations or oral mycosis. 5. Acute or chronic inflammatory or infectious upper airway diseases (excepted mild to moderate asthma) including recurrent acute or chronic sinusitis. Note: Patients with fever, flu or an upper respiratory tract infection at Visit 1 (screening visit) must be treated appropriately. They can be randomised at Visit 2 (randomisation visit) only if the infectious episode is resolved. 6. History of eosinophilic oesophagitis. 7. A relevant history of systemic allergic reaction (e.g., anaphylaxis with cardiorespiratory symptoms, generalised urticaria or severe facial angioedema) that, in the opinion of the Investigator, may constitute an increased safety concern. 8. Any disease that prohibits the use of adrenaline (e.g., hyperthyroidism). 9. Any severe, uncontrolled disease that, upon Investigator judgment, could increase the risk for trial patients (including but not limited to cardiovascular insufficiency, any severe or unstable lung diseases, endocrine diseases, clinically significant renal or hepatic diseases, haematological disorders, diseases of the immune system including autoimmune diseases and immune deficiencies of current clinical relevance, active malignancies). Screening Tests and Evaluations 10. Any significant abnormal laboratory parameter or alteration in vital signs that could increase the risk for the patient, in the opinion of the Investigator. Medication 11. Ongoing treatment with prohibited treatment as listed in Section 8.2.3 or any allergen immunotherapy product including Specific Immunotherapy (SIT), or past full courses of SIT against birch pollen terminated for less than 5 years or past courses of SIT for other allergens terminated for less than 6 months prior to start of randomisation. 12. Patients requiring continuous treatment with systemic corticosteroids for any indications. 13. Patients requiring continuous treatment with ß-blockers or with Monoamine Oxidase Inhibitors (MAOIs). 14. Treatment with an immunosuppressive (Anatomical Therapeutic Chemical code L04 or L01) within 3 months prior to the screening visit. 15. Hypersensitivity to any excipients of the IMP or placebo, or contraindication to the use of RMs (i.e., antihistamine and nasal corticosteroids). 16. Patients following a strict low sodium diet as the IMP treatment contains 590 mg of sodium chloride per vial in a 10 mL solution. 17. Inability to adhere to the washout periods as defined by the protocol, with respect to screening and to refrain from using the medications indicated until after the trial is complete. 18. Patients who would be likely to require prohibited concomitant therapy during the trial or who are anticipated to require using of such agents during the trial. Any medication given for an AE will be permitted. Other 19. Breastfeeding females (lactating). 20. Sexually active females of childbearing potential or who have had their first menarche prior to randomisation who are not taking and/or willing to use either 1 highly effective contraceptive method or 2 clinically acceptable contraceptive methods until the end of the trial (depending on the local regulation): - Abstinence - Acceptable highly effective methods of contraception 1. Non-cyclic, stable dose (monophasic) combined oestrogen-progestin oral hormonal contraception associated with consistent inhibition of ovulation. Oral contraceptives containing oestrogens should be in stable use for at least 12 weeks prior to Screening. 2. Desogestrel based progestin only contraception associated with consistent inhibition of ovulation; this includes oral, injectable, and implantable methods 3. Intravaginal and transdermal hormone delivery methods 4. Intrauterine device (with or without hormone elution) - Clinically acceptable methods of birth control 1. Male or female condom with or without spermicide 2. Norethindrone-based progestin-only oral contraceptives 3. Cap, diaphragm, sponge with spermicide. 21. Participation in any clinical trial within 30 days prior to the screening visit. 22. Change in residence between geographical regions since the last birch pollen season or anticipated relocation away from the geographical region during the pre-determined birch pollen seasons for more than 2 weeks. 23. Patients who are non-compliant and/or uncooperative, in the Investigator's opinion. 24. Possible dependency of the patient or patients' parents/authorised legal representative(s) on Sponsor or Investigators/sub-Investigators or trial personnel. |
